| HaltingState | i was at burning man and found company that did the CNC routing for 'lost hotel', but they outsource their aluminum CNC /routing to other companies |
| HaltingState | i am almost giving up and going to shenzhen china or buying my own CNC machine |
| ohsix | ah buns |
| ohsix | techshop is opening a space in LA soon, i thought they were already there |
| ohsix | they're in sf, san jose, menlo park though~! |
| ohsix | http://www.techshop.ws/tools_and_equipment.html :< |
| ohsix | HaltingState: it is like a gym except they have tools and a workspace |
| HaltingState | ohsix, is there a directory!? wtf |
| sammyb | man i love this communal workspace movement which is happening now |
| sammyb | fucking awesome stuff |
| HaltingState | ohsix, i am googling 'club company' cnc, cant find anything; am i using wrong keyword |
| ohsix | i was thikning of techshop |
| ohsix | hackerspaces.org have regional listings of other types of clubs or schools or whatever |
| hjf | guise |
| hjf | i want to make a BIG SMPS |
| hjf | like |
| hjf | 500W |
| hjf | 50V 10A |
| jnewt | i cannot get this circuit to work: http://tinyurl.com/p2crt92 |
| ohsix | why tinyurl, that's kind of shady |
| hjf | any idea what ic can i use for this |
| bulaia | how is tinyurl shady |
| jnewt | how specific do the components need to be? i have a .047uf in place of .1uf, 2.2uf in place of 1uf and fdc6420c mosfet |
| ohsix | why would you obfuscate a url you can just post |
| ohsix | this isn't twitter |

| jnewt | http://www.lakehomes.com/ |
| jnewt | http://www.landwatch.com/ |
| jnewt | wtf |
| jnewt | i quit |
| hjf | jnewt: try two .047s in parallel for ~0.1uF and 2 2.2uF in series for ~1uF |
| ohsix | so it is |
| hjf | jnewt: and make sure you're connecting your P and N mosfets right |
| jnewt | hjf: do you think that would cause it to not work, small variations for that? i've checked the mosfet |
| hjf | jnewt: no idea |
| jnewt | i can't really understand what the different node signals should be to trace the issue. i understand the concept, but that's about as far as my brain can get |
| hjf | guise |
| hjf | anyone know a big bad smps ic i can use |
| hjf | i found some TDAsomething but it's only 250W |
| hjf | i need 400 cause i'm macho |
| ohsix | you would use a small one and big switching elements |
| hjf | i have big BIG switching elements |
| hjf | like |
| hjf | from old plasma PSU boards |
| hjf | those things are beautiful |
| hjf | good luck finding a cap that's not a nichicon in there |
| flyback | CE# |
| flyback | does that mean it's grounded to enable |
| flyback | cause I want to kill the firmware on this old router to use as switch only |
| hjf | flyback: yes # is bullshit for 'NOT' |
| ohsix | my friend works in 'power' and they've got big bins of coke can nichicon stuff all over the place |
| flyback | so if I cut this trace will that do it? |
| jnewt | my problem is, it comes on in the 'on' state, even though i tied the gate cap to the input voltage to i 'think' pull the pfet high, thereby blocking the curretn flow |
| hjf | ohsix: http://i.imgur.com/m2QC7zO.jpg |
| ohsix | nice |
| ohsix | http://i.imgur.com/ga7jDuS.jpg |
| ohsix | i was looking for a picture of the nippon chemi-con (not nichicon) parts they had but then i asked myself what i was doing |
| ohsix | they are big, the end |
| ohsix | http://en.wikipedia.org/wiki/The_Unreasonable_Effectiveness_of_Mathematics_in_the_Natural_Sciences |
| hjf | hm |
| hjf | ST recommends L6566 |
| hjf | but it needs Litz everywhere in the transformer |
| SuperBrainAK | hjf what are you making/doing? |
| SuperBrainAK | how does the ic determine the wattage? shouldnt it go to some mosfet or something? |
| SuperBrainAK | bedtime, gl with whatever you are making hjf |
| Casper | hjf: what is a good thru-hole opamp that is bellow the rail input with rail to rail output, suitable for single supply and very low input voltage? as in current shunt amplifier |
| hjf | Casper: i use max4080 but it's not TH. its SOIC so you can adapt easily |
| hjf | ah no, max4080 needs like several volts |
| hjf | you can use INA199 i think, |
| hjf | max4081 can do it but it's not signle supply |
| hjf | also wtf |
| hjf | some client sends me a message to my FB business page: |
| masteraccurate | gooooooood morning dudes! :) |
| hjf | 'i would like to know if you'll be at the convention next week and if you'll be taking stuff to sell' |
| hjf | and i'm like |
| hjf | dude |
| hjf | i'm open 300 days a year |
| masteraccurate | question: someone of you is using sedo.com for selling domaims? |
| hjf | and you cunt want me to go and work on a sunday so you will buy shit from me |
| hjf | when i just looked at your fucking FB profile and it's full of pics in a place like 8 blocks from here |
| Casper | hey hjf! it's advertisement!!! |
| hjf | dude. DUDE. |
| hjf | Casper: yeah i know but it's expensive advertisement. you have to pay for the place, for the things that get lost, the things that get stolen.. and dealing with retard kids for 2 days 12 hrs day |
| hjf | fuck that shit |
| hjf | i'm too old for that |
| Casper | man this will be a very painfull order to sort out.. |
| hjf | how much is this keychain? |
| hjf | $2 |
| hjf | oh, and this one? |
| hjf | $2 |
| hjf | and this one? |
| hjf | $2 |
| hjf | and this one? |
| hjf | dude they all have a price tag, see ? |
| Casper | I'm restocking on resistors |
| hjf | ooooooooh i didnt see thanks |
| Casper | I'm low on most values< |
| hjf | and this o. oh here's the price. it's $2 |
| hjf | THIS ONE!! THIS ONE DOESN'T HAVE A PRICE TAG. HOW MUCH IS IT? |
| hjf | $2 like all the others |
| hjf | ooh. ok thanks bye |
| hjf | FUCK man |
| hjf | who the fuck are they |
| hjf | price tag inspectors |
| genewitch | humans |
| genewitch | humans that vote |
| hjf | genewitch: no, they're kids |
| hjf | but still |
| hjf | fucking idiots |
| genewitch | time is irrelevant, i am sure they'll vote sometime |
| hjf | like not kid kids |
| hjf | they are like 16 |
| hjf | which is worse cause they're able to breed at that age |
| Casper | 24 resistors values.. |
| hjf | Casper: from digikey? |
| Casper | I hope the packages will be identified |
| Casper | yes |
| hjf | Casper: they are, they come in individual bags with a label |
| hjf | Casper: but why dont you buy on obay |
| hjf | ebay |
| hjf | the assorted resistor thing |
| hjf | 5000 resistors for like $10 |
| Casper | most likelly won't have the values I want |
| hjf | cause it's fucking annoying to go to digikey. search the value. check 'in stock only' 'cut tape' '0805 size'....etc |
| hjf | then sort by price, choose the cheapest.. |
| hjf | and repeat for the next 23 values you need |
| Casper | it's done already |
| Casper | don'T forget the quantity |
| hjf | quantity is 100 dude |
| hjf | next up is 250 but who needs 250 resistors |
| hjf | unless you're buying .1uF caps |
| hjf | those you buy in 500 |
| RoBo_V | Morning Guys ! |
| mrdata | yep |
| hjf | and 0603 size |
| hjf | cause fuck trying to fit a 0805 near a .5mm TQFP |
| hjf | unles you're azonenberg and do like 0003000001 size |
| mrdata | in units for RC timing constants |
| azonenberg | hjf: 0805, lol |
| azonenberg | the only reason to use 0805 is a) high-power ish resistors |
| mrdata | 100 ohm? |
| azonenberg | and b) really high capacitance that you cant get smaller |
| azonenberg | also i buy 0.1 uF caps in qty 10,000 |
| hjf | azonenberg: c) high caffeine intake |
| azonenberg | after the last order of 1000 ran out |
| azonenberg | Lol, thats a justification too i guess |
| hjf | azonenberg: 10K? dont they come in 4K a box? |
| azonenberg | in which case i say cut back, man up, and learn to do 0402 |
| azonenberg | hjf: The 0.1 uF caps i have come in reels of 10k |
| azonenberg | meant to feed right into a PnP |
| hjf | azonenberg: come on i dont have solder mask |
| hjf | azonenberg: i ordered some 1812 caps today |
| hjf | 2.2uF 100V large enough to fit a fat trace under it |
| Polesch | I hate darlingtons!! |
| hjf | azonenberg: http://i.imgur.com/sttiJCA.png |
| intranick | they're not your darlings, Polesch ? |
| Polesch | Nope |
| Polesch | Are variacs generally rated in RMS or p-p? |
| Casper | hjf: is there some cheap ttl-usb serial modules on digikey? |
| Casper | I guess I'm better china order them |
| anton02 | Casper: should i use a certain PCB thickness if I'm using 3oz copper? |
| Casper | anton02: do you require special thickness? |
| anton02 | no |
| anton02 | well, depends on what thickness influences |
| t4nk518 | halo. |
| t4nk518 | I am looking to interface a 16bit dac with msp430f5529 board. |
| t4nk518 | my application is to make 0 to 50v digital power supplly and i need .01 precision. |
| Casper | anton02: board thickness mainly influence the weight and flexibility |
| t4nk518 | i found 16 bit dac pmod single channel peripheral module in digilent site. but its output is given to SMA connector. |
| Xark | t4nk518: For audio use, you may prefer http://www.xess.com/shop/product/stickit-audioio/ |
| t4nk518 | I will need to connect output of dac to opamp circuit for converting it into 0 to 50 v. is there any way to takE SMA connector out to another circuit. |
| t4nk518 | not audio use. i am looking to make 0 to 50 v digital supply. |
| Xark | t4nk518: Gotcha. |
| jpa- | t4nk518: 0.01 what? volts? better make sure your DAC is very linear then |
| Xark | t4nk518: What is wrong with a cable with a SMA connector on it? |
| jpa- | t4nk518: why not just use a DAC chip? |
| t4nk518 | i am looking for 16 bit dac for that precision. |
| jpa- | just being 16 bit does not guarantee the linearity |
| jpa- | 0.02 % linearity is quite rare AFAIK |
| Casper | what is some good thru-holes opamp that is good for current shunt amplification? |
| Casper | nite |
| jaggz- | night Casper |
| sndp_12 | is there any SMA out to pcb header type connector available. |
| sndp_12 | i need to take output of DAC with SMA OUT to another circuit.. |
| sndp_12 | halo |
| jpa- | eh, just take a SMA connector and solder to it? |
| archivist | you can get pcb mount sma sockets |
| AkashicLegend | is it worth my time learning about karnaugh maps |
| AkashicLegend | or can I skip them |
| LeelooMinai | AkashicLegend: I am programming for very long time and never used them - imho they have zero practical value. |
| AkashicLegend | got it I'll gloss over them |
| AkashicLegend | they seem more theory than practical |
| LeelooMinai | AkashicLegend: Unless someone will ask you to implement them - but that's unlikely:) |
| AkashicLegend | to use microcontroller or even build cpu with logic gates it is not nescessary to know them |
| AkashicLegend | right |
| archivist | for electronic design you may well want them to minimise the part count |
| LeelooMinai | But no one sane will do it by hand |
| archivist | sure they do |
| LeelooMinai | They are not sane then:p |
| AkashicLegend | Think I'll skip them. Quartus does the same job. |
| AkashicLegend | In 2 seconds. |
| archivist | designers are sane they have to be |
| AkashicLegend | I can never beat the speed of a computer. |
| archivist | a computer may not have the best solution, just one it found |
| LeelooMinai | archivist: You want to beat computer at optimising gates? |
| joze | can I assume that all minimelf resistors are 0.25W? |
| joze | or at least over 0.125W? |
| Mr_Sheesh | Look at the datasheet for them? |
| joze | i have a roll of old leaded ones and can't find one |
| archivist | LeelooMinai, do you think a computer would ever use a 7474 as an inverter to save money |
| LeelooMinai | archivist: You can use what you want and still use computer to optimized the final circuit. |
| archivist | we had a spare 7474 and needed an inverter, one less chip needed |
| LeelooMinai | optimize* |
| archivist | I think you miss the point |
| LeelooMinai | archivist: I thought your point is that doing such optimisation on paper is useful. |
| archivist | you need to know how in order to do |
| LeelooMinai | No you don't - you can use software |
| Mr_Sheesh | Best to know how anyways |
| archivist | using a crutch means you are never fully skilled |
| soil-d | well karnaugh maps a re useless when big but it's not like uber complex to not take the time and understand them :P even if you forget it |
| LeelooMinai | In this case I would say no - it's a mechanical procedure that will not give you anything valuable over just using software to do that |
| archivist | using software does not make you clever |
| LeelooMinai | archivist: But using right tools does:) |
| archivist | software is not always the right tool! |
| caesius | archivist: yeah screw software ;) |
| soil-d | it's not an excuse to not understand something |
| LeelooMinai | archivist: And doing things by hand is not always the right idea too. |
| LeelooMinai | Unless you have boundless brain that can learn everything there is in the world. |
| soil-d | especialy something you can learn in few hours |
| archivist | remember I do both manual and cnc |
| LeelooMinai | soil-d: In that few hours I can think of just about anything that would be more useful than learning those maps. |
| soil-d | like what hanging on irc ? |
| LeelooMinai | soil-d: If you get some useful info out of it - why not? :) |
| day | soil-d: if your irc time is paid. yes. |
| LeelooMinai | Truely, I don't understand the point here - learning enything there is without deliberation does not sound like a wise strategy to me. |
| caesius | so I got marked down for knowing perl in a software interview today.. |
| bulaia | lol what |
| day | he has seen the dark side. we can not let him corrupt our minions :D |
| LeelooMinai | caesius: You see - my point exactly:) |
| bulaia | wtf is so bad about perl |
| bulaia | i cant stand python nazis |
| bulaia | if you cant read my code, get a refund on your brain |
| intranick | LeelooMinai: hihi |
| LeelooMinai | caesius: Maybe the marker thought 'PERL, ha! - this person needs to learn how to spend time learning more useful things than that' :p |
| archivist | perl! the nice thing about perl is you can just slam your fists at the keyboard at couple of times, and you have something that runs and does something, you just wont know what and the maintenance of it will be impossible |
| archivist | |
| bulaia | yea like art history |
| caesius | bulaia: yup, agree |
| archivist | 0001ACTION checks caesius's hobbies and marks down any kicking balls about 0001 |
| LeelooMinai | PERL is good if you want to make some crazy one-liner or something like that, that will process some text, otherwise it's just an ugly language. |
| intranick | its a nice language for its simplicity imo |
| soil-d | mmm |
| bulaia | i can make beautiful things with its ugliness |
| caesius | I dunno, i like that it reads like a natural language |
| soil-d | perl looks to me for people with down syndrome |
| caesius | do this for this or die .. |
| spybert | There are many ways to code in perl, it`s a matter of style |
| soil-d | i felt rather atacked by someone just ranting on some language i actualy like now i feel i have to be an ass :( |
| caesius | yeah I don't mind ppl with valid objections to perl, but it irks me when ppl are like 'perl sucks!' 'why?' 'I dunno thats just what everyone else says' |
| day | LeelooMinai: i disagree. imo python is ugly |
| LeelooMinai | PERL became popular mostly because at that time there were not many alternatives to scripting languages like that |
| LeelooMinai | But that was long time ago:) |
| bulaia | python is annoying |
| soil-d | i looked at perls syntax and it's clearly nmore crap then pythons |
| jacekowski | scripting languages suck |
| caesius | yeah python is weird. let me have whitespace, and a swtich statement then we'll start talking |
| jacekowski | performance is always an issue |
| day | the missing $%@ variable tags and the forced indenting is super annoying |
| jacekowski | and with perl you have compatibility issues as well |
| bulaia | thank you day |
| jacekowski | so extension for 5.5.1 will not work with 5.5.2 |
| bulaia | i get by fine with perl for my light stuff |
| spybert | caesius: The thing with job interviews is that they might be testing your personality with deliberately obnoxious questions |
| bulaia | idc to learn anything else. |
| bulaia | i dont use it for my job |
| day | oh and dont forget the forced () for a stupid print() command in python 3 |
| caesius | spybert: yeah, you're probably right. suffice to say I didnt put up much of a fight, just said i'd learn whatever they used |
| jacekowski | day: ??? |
| jacekowski | day: that makes the whole thing a lot nicer |
| soil-d | and also flase |
| jacekowski | day: it's still a function and as a function you have () |
| day | jacekowski: you want to check something real quick: print variable. NOPE |
| caesius | damn software jobs. if anyone knows of any hardware roles in NZ, let me know ;) |
| spybert | caesius: Most positions are filled by people with contacts inside the company. Others are interviewed simply to make it look legit |
| jacekowski | people not using brackets should be shot |
| jacekowski | and i mean that for any languages |
| jacekowski | C, python, perl, |
| day | its kinda hard not to use brackets in C |
| LeelooMinai | caesius: FOr them it was probably like a guy trying for a job as professional car driver and putting 'Vehicle of choice - Yugo' on the application. |
| jacekowski | you can do something like if (foo) bar(); |
| jacekowski | day: which will work fine if bar is a proper function |
| jacekowski | day: but if bar is a macro, things will go wrong |
| day | jacekowski: but you can replace certain brackets by others :P array[i][j] *(*(array+j)+i) |
| jacekowski | as well as ternary operators |
| day | and as always: the amount of pointers determines the skill level. aka more pointer more good |
| jacekowski | what about people coding in c# |
| LeelooMinai | Unless a language does not have pointers - then it's pointless. |
| day | to learn it |
| day | correct |
| jacekowski | c# will hate you for using pointers |
| LeelooMinai | Java does not have pointers too |
| day | references are a last resort i guess. |
| LeelooMinai | day: Let it be a pointer to you that pointers are not determinant of a skill level:) |
| day | the java boys are running wild |
| bulaia | ok this conversation got silly |
| LeelooMinai | day: Peconceptions, preconseptions |
| nightw0lf | LeelooMinai hello :) |
| Haxxa | How would I go about making a audio switch that automatically switches when one input in playing and another is not |
| Haxxa | like when one input goes high it switches to it |
| archivist | Haxxa, you sense the amount of signal to do the switching |
| Haxxa | yes how? |
| Haxxa | could this be donewith a basic mc |
| archivist | a diode and a level detector |
| archivist | a few caps resistors and a comparator, and a switching device (relay or whatever) |
| Haxxa | switching is done and set up with relay (audio quality) |
| Haxxa | anyway I can do this without touching the source signal (affecting quallity) |
| archivist | how are you going to deal with quiet periods (relay clicks) :) |
| Haxxa | ;) |
| Haxxa | It only switches once a day |
| Haxxa | but manually doing so is undesirable |
| archivist | methinks you are confused about what you want |
| Haxxa | when I play from my computer it plays through speakers |
| Haxxa | when I play from my dac it plays through speakers |
| Haxxa | no manual switching or mixing |
| morski_pas | and what when it plays from both? |
| caesius | LeelooMinai: lol |
| caesius | well this was an embedded role so not quite but I get your point |
| caesius | where are all of the VCO design roles. transmitter/receiver design roles. SOMEWHERE in the world must be doing them! |
| archivist | I dont think I have seen VCO as a separate job |
| caesius | we have VCO designers at work |
| LeelooMinai | Very Clumsy Operator? |
| intranick | me puts LeelooMinai in a box |
| caesius | but they are disappearing daily. in fact most of hardware eng is |
| archivist | 0001ACTION teaches intranick how to use irc /me0001 |
| archivist | all the jobs are being exported to cheaper places |
| intranick | 0001ACTION ships LeelooMinai to china0001 |
| Mr_Sheesh | India and Ireland for lots of embedded jobs |
| LeelooMinai | That would be nice - all those nice cheap parts and then being executed for using internet |
| Mr_Sheesh | India MIGHT be a lil safer than China.. |
| LeelooMinai | With all those cobras running around - I don't know |
| ohsix | 'designed and assembled in the usa by tobacco experts' LOOOOOOOOOOOOOOOL |
| ohsix | electronic cigarette ads are insane |
| intranick | lol |
| Mr_Sheesh | I'd just carry a snake stick. LOL |
| LeelooMinai | I would have a mongoose in the pocket |
| Mr_Sheesh | 0001ACTION watches LeelooMinai turn into a crazy mongoose lady :p0001 |
| LeelooMinai | Or on a leash, yes |
| Mr_Sheesh | (Ofc I'd probably classify as a crazy cat guy, so, eh, whatever.) THat works. |
| intranick | 0001ACTION wonders how many cats LeelooMinai has0001 |
| LeelooMinai | Just one, abandoned by my sister |
| intranick | you sure its not like 6? |
| intranick | you seem like a crazy cat lady :D |
| ohsix | there are normal cat ladies |
| Mr_Sheesh | I have 2 ATM, both rescues to some extent (Older one from humane society from a hoarder house, younger one had constipation as a kitten and was freaking out from that, as they see everything as 'an animal' so she thought an invisible monster was biting her gut..) There are normal cat guys too |
| LeelooMinai | Yes, those with only 5 cats |
| ohsix | have you looked at animal hoarding, it is some sort of weird projection of responsibility |
| intranick | oh trust me ohsix LeelooMinai is crazy |
| ohsix | heh |
| intranick | 0001ACTION would not give LeelooMinai a machine gun for fear of culling of the male species0001 |
| ohsix | maybe start with a handshake |
| Mr_Sheesh | I think it's something rage-related, the people who hoard animals do NOT take good care of them, mine from the hoarder house is SO damn happy to be here, she trills at me if I do about anything - Poke her with my holly wood cane, she gnaws on it, purring and trilling.. She's pretty spoiled now :) |
| LeelooMinai | Yes, well, some people do not really judge what is good or bad for animals. They will feed them food that will kill them thinking they do a good did, or try to domesticate wild animal, etc. |
| Mr_Sheesh | I can tell she didn't have clean water ever (used to beg for fresh water any time I got near a faucet) or food (she used to beg for food even tho she had the food hopper and wet food 2x/day etc.) I've heard of vegans trying to feed their cat only veggies, that's a different form of crazy |
| ohsix | ergh |
| LeelooMinai | Or keep some wild creature then let it go and the creature will die because it has not learned to live in the wild. |
| ohsix | they can't even live on a diet of veggies |
| LeelooMinai | lol at vegetarian cat |
| Mr_Sheesh | I know; They NEED taurine etc. and they're carnivores, not omnivores |
| ohsix | need energy drinks |
| intranick | LeelooMinai: you know im just picking on you for fun right? |
| LeelooMinai | 0001ACTION imagines two ladies talking wghile drinking tea and one saying with pride 'All my cats are vegetarians'0001 |
| Mr_Sheesh | Francine also loves wheatgrass, she just noms that when I get her one :) INdoor-only cats as I'm in an apartment |
| LeelooMinai | Cats eat grass so they can throw up actually:) |
| frimend | http://en.wikipedia.org/wiki/Cat_food#Vegetarian_or_vegan_food |
| frimend | 'Vegetarian cat food must be fortified with nutrients such as taurine and arachidonic acid that cats, as obligate carnivores, cannot synthesize from plant materials.' |
| Mr_Sheesh | Also for the vitamins and minerals. She doesn't throw the grass up, but she loves the plant to death, pulls it out of the pot, gnaws on it, cheek rubs it to death LOL |
| intranick | i have a vegan friend that will kick anyone's ass whom tries to make their cats vegetarian |
| intranick | he will take an axe and put it in the back of their heads. cats are obligate carnivoures, we are not. |
| frimend | Cats can metabolize many vegetarian foodstuffs. |
| evilbetty | i saw a dead cat this morning |
| frimend | Why are your friend such a crazy person? |
| Mr_Sheesh | I'm easier, I'd just catnap the cat from that insane person |
| intranick | cats can matabolize some things from vegetarian foodstuffs |
| intranick | but they require high octane fuel |
| evilbetty | lol at hippies forcing thzir food habbits on cats |
| evilbetty | or even children |
| Mr_Sheesh | Yeah that's what 'Obligate carnivore' means |
| intranick | if you try to give them only vegetarian foodstuffs |
| ohsix | is someone even suggesting that vegetarian diets in cats are ok? |
| intranick | they fucking die. |
| intranick | ohsix: a lot of people have tried. and lost their cats. |
| evilbetty | some hippies and vegan scum is |
| Yotson | eh? cats can live fine on vegetarians. |
| frimend | ohsix: I'm saying that one doesn't need to be so extreme, in either case. |
| Yotson | oh wait.. |
| frimend | It's not black/white. |
| evilbetty | its not the first time i hear this, i even think they shouldnt force their eating habbits on their own nongrownup kids |
| frimend | People here are obviously extrely emotional about the issue. |
| Mr_Sheesh | Humans can handle a veggies-only diet, but, you need to supplement for humans with extra protein; Feeding cats unsupplemented veggies will cause malnourishment, so I'd just take the cat away from that IDIOT. |
| frimend | evilbetty: Are you serious? Any diet you give your kid is 'forced' upon them. |
| intranick | cats are designed to run off meat |
| intranick | humans are designed to run off whatever the fuck we find |
| intranick | we have it lucky |
| Mr_Sheesh | Yep we're omnivores but we need SOME extra protein if just eating JUST veggies |
| evilbetty | ah well |
| Mr_Sheesh | I have vegetarian friends and they use protein powder to keep healthy; I've eaten many different diets, 'Diet for a small planet' recipes are pretty good and I've eaten a lot of that fare :) |
| evilbetty | i dont really care as long as they shut the fuck up when they come to a bbq |
| frimend | Mr_Sheesh: I got news for you. Vegtables contain protein. |
| frimend | lol |
| evilbetty | but thats not just veggies, thats those tofubitches that come to a bqq to then bitch on the food |
| Mr_Sheesh | frimend - Yes, just not enough for humans, in the usual mix we eat |
| frimend | >_< |
| evilbetty | they keep calling emails that contain a virus fishing emails in the official comms |
| frimend | beef: 26%, oats 17% |
| Mr_Sheesh | I am allergic to Lima beans of all things; I just forewarn the hosts and then eat anything they've said is OK that they have. Being an ass is being an ass, I won't go there LOL |
| evilbetty | a virus email is not the same as a phishing email |
| ohsix | who is people here |
| ohsix | being emotional |
| ohsix | don't get scurvey |
| evilbetty | they're emotional because they need a good piece of meat :p |
| evilbetty | im not emotional, i just hate vegetables guitars and djembees :p |
| evilbetty | and unwashed hair |
| frimend | Painting up a ridiculed stereotype and attacking that, to justify your own eating habits? |
| nnumerals | what are europes top electronics dealers? |
| Mr_Sheesh | nnumerals - Farnell, RS, hmm who else |
| Mr_Sheesh | 0001ACTION is in the US so I've seen them but not dealt w/ them0001 |
| nnumerals | ic |
| nnumerals | what about retailers |
| nnumerals | where do you buy a tv n shit |
| Mr_Sheesh | look on http://findchips.com/ and what is the name of that other similar site? Hmm in the UK there's that one, dang what IS their name |
| nnumerals | http://globalpurchasing.com/top-50-distributors/top-50-electronics-distributors-2012 |
| Mr_Sheesh | Maplin |
| nnumerals | any in mainland europe? |
| evilbetty | those stereotypes are not ridiculous, i have them over my door nearly every week |
| Mr_Sheesh | (Maplin.co.uk) they sell a lot of varied electronics. IDK, sorry |
| nnumerals | hm |
| evilbetty | well they are ridiculous, but they're doing lots of effort for it |
| nnumerals | thx |
| evilbetty | last time they were doing a drumcircle with djembees at 4am |
| ohsix | these boots let you jump higher |
| frimend | evilbetty: Ok, the thing I have a issue with is this basically: 'think they shouldnt force their eating habbits on their own nongrownup kids |
| frimend | ' |
| evilbetty | jumping boots? |
| frimend | evilbetty: Anyone who gives their child the same food as they eat themselves, do that. |
| evilbetty | yes, you can have issues as much as you want, i dont feel like discussing your hippie crap at all |
| evilbetty | you could use this time of nondiscussing for taking a shower |
| frimend | You feeding your child bbq meat, would be 'forcing your eating habits' on it. |
| evilbetty | i dont have children |
| Yotson | even better, don't get kids. |
| frimend | evilbetty: totally beside the point. |
| ohsix | get aids |
| ohsix | what's the line between 'force' and 'teaching them how to eat at all' |
| frimend | evilbetty: You are acting stupid in a way which I dislike. |
| ohsix | frimend: as are you, that's why evilbetty is saying these things |
| ohsix | have other peoples kids |
| ohsix | for lunch |
| evilbetty | lets go save the rainforest |
| ohsix | more like the blameforest am i ite |
| frimend | ohsix: I try to keep my worldviews at least internally consistent. |
| frimend | ohsix: If that offends, I'm glad it does. |
| Yotson | are you a computer? (and even than..) lol |
| ohsix | frimend: yea i'm not sure it's about the world view or the being offensive |
| ohsix | the indignity! |
| Mr_Sheesh | Hmm I think I see a ceiling cat :p |
| evilbetty | impossible |
| evilbetty | i applied vaseline to the ceiling when noone was looking |
| evilbetty | and 1 spot of superglue :p |
| Mr_Sheesh | Well, we'll see. Claws aren't impressed by that :P |
| waressearcher2 | may of you familiar with that home made EMP device made out of disposable camera, you just plug a coil to it, but is there a way to direct that EMP ? otherwise you need to put device right onto that coil, is there a way to make that EMP reach farther away from coil ? |
| evilbetty | i was doubting this morning if i should stop my car and poke the dead cat with a stick, or continue to work |
| evilbetty | i may have made the wrong choice, work isnt being fun today |
| ohsix | gesticular cancer |

| evilbetty | im not interested at all in your bs |
| Mr_Sheesh | 0001ACTION just sheeshes0001 |
| frimend | evilbetty: I'm just being friendly, replying to your joke. |
| evilbetty | letme check what ebay returns with 'anti-cat' as search |
| evilbetty | ill be friendly putting you on ignore then |
| frimend | Have a field day. |

| evilbetty | no matter what you look for on ebay, some screen protectors for phones will sneak in your results |
| evilbetty | i need those chinese 100W led lenses |
| evilbetty | i dont think they actually bundle very well tho |
| Haxxa | I have a bed and I want either side to have an audio jack (3.5mm) but I only have one input, can I just solder left, right, ground together to make a y cable - there will never be two devices plugged in only one at at time either side of the bed or will this add noise? |
| ohsix | Haxxa: yes |
| Haxxa | I can or no I can't |
| Haxxa | Or it will add noise |
| ohsix | yes you can |
| zap0 | what if china invaded somewhere, and political sanctations were enforced, and you couldn't buy stuff from china ? |
| ohsix | the possible sources of noise won't be any greater than just having a long cable |
| evilbetty | headphone outputs are pretty loaded i wouldt worry for noise |
| ohsix | i have sort of the same thing, but i put the lead above th ebed and it works at any place on the bed :> |
| ohsix | can hang up the headphones too |
| Haxxa | sure - and really the only form of noise will be from the jack touching soething else |
| zap0 | Haxxa, is the sockets you use make-break connectors? cause some are. be careful |
| Haxxa | I was going to get some audio connectors and do this on a breadboard - unnessersary but saves me messing around with cables to solder |
| veek | crud - i tried contacting a nvocc for shipping but they told me to go to dhl |
| zap0 | Haxxa, some sockets short the tip/ring to ground when there is no plug inserted. |
| veek | and shipping may be reaaly cheap but customs documentation is horrendous |
| Haxxa | ah, good point |
| Haxxa | zap0 do these- http://www.ebay.com.au/itm/5-Pcs-3-5mm-Headphones-Audio-Stereo-Jack-Power-Socket-PCB-Panel-Mount-Soldering-/301194799362?pt=LH_DefaultDomain_15&hash=item46209be902&_uhb=1 |
| zap0 | Haxxa, maybe. |
| Haxxa | zap0 can you link me to some that don't and are easy to solder to protoboard? |
| evilbetty | just get a premade y-cable |
| zap0 | nope. |
| zap0 | i do technology; not shopping. |
| Haxxa | http://www.ebay.com.au/itm/Earphone-Y-Splitter-3-5mm-Jack-2-Plug-Audio-AUX-Cable-Auxiliary-Stereo-Adapter-/111323175867?pt=AU_Electronics_Portable_Audio_Accessories&var&hash=item19eb60dbbb&_uhb=1 |
| Haxxa | slitter cable right should work just as well |
| Haxxa | for my purpose |
| Mr_Sheesh | If you want the least noise then a shielded cable, or, 2 twisted pairs (ground + Left and ground + Right) are best |
| Mr_Sheesh | but headhpones are driven hard enough that a ribbon cable should be OK anyways |
| ohsix | how is two ground paths along the entire cable better than one |
| Mr_Sheesh | Can leave one of the 2 disconnected at the jack end |
| evilbetty | *yawn* |
| Haxxa | cool I will just get a splitter seems like overcomplexing something simple |
| Haxxa | and yes I make up words |
| Haxxa | I was going to buy $50 mixer - :0 sometimes brain is turned off |
| evilbetty | oh boy |
| evilbetty | i wonder why they rehired this annoying dude |
| evilbetty | evrry time i go smoke he follows me and im tired of him, i was glad he left |
| ss23 | evilbetty: He likes you! |
| LeelooMinai | He must have fallen in love with evilbetty's charming IRC personality |
| scrts_w | and he gets a boner when the smoke goes out of your mouth |
| Mr_Sheesh | Quit playing so hard to get, evilbetty |
| veek | is there an easy way to plot a graph from a table of values - cut and paste and click, presto: http://imgur.com/XxS0V3A |
| ohsix | you can already be good at gnuplot, plplot, or have excel or mathematica |
| veek | gnuplot doesn't have a gui so i got to vi and switch back and forth |
| veek | i just want a quick paste and click solution - that's key |
| ohsix | have you tried pasting it into wolfram alpha and see what it does? |
| veek | lemme check plplot |
| ohsix | plplot is the same, just more |
| Evidlo | I like using octave for this kind of thing |
| veek | ugh. . yeah api library |
| veek | ah okay lemme check |
| ohsix | yea octave/r has stuff |
| Evidlo | What does the data look like when you paste it into a text file? |
| ohsix | then you end up entering it into that, but at least you can do math-y things when you do |
| ohsix | i want something like a fog machine that excretes marshmallow |
| veek | Evidlo, well all the spaces and commas will f! things up |
| veek | so i got to tr all that which is a pain to type |
| Evidlo | veek: no they won't |
| Evidlo | use data=dlmread('file.txt','t') |
| Evidlo | veek: actually use dlmread('file.txt',' ') |
| Evidlo | lern2matlab |
| t4nk213 | hi can anybody help me to understand how this circuit work http://zpostbox.ru/sine_wave_signal_generator.html |
| evilbetty | itq just a DAC followed by a voltage follower as buffer |
| ohsix | if he knew matlab surely the question need never have been asked |
| evilbetty | google R2R dac for info on how to make a DAC with resistors |
| t4nk213 | where does the shift regester get is data |
| t4nk213 | ? |
| Mr_Sheesh | 47hc4094 tho? More likely a 74HC4094 :P The counter does it on its own, by design, IIRC those are a Johnson Counter |
| t4nk213 | ok |
| evilbetty | and dont expect much from it |
| Mr_Sheesh | Maybe not tho, it's late LOL - Way past tired here. It'd be OKish but not a perfect sine wave generator |
| Mr_Sheesh | easy tho :) |
| blown | hi. |
| blown | how are they! |
| medfly | woo |
| medfly | got a breadboard |
| medfly | COMPONENTSESESES |
| blown | ! |
| raffahacks | I've bought a HDMI VGA converter yesterday in a good electronics shop for 15$, but i get no signal.. |
| medfly | what are those reisstors I have that are brown and look woody rather than off white |
| medfly | some of them are gigantic |
| ohsix | ELECTRONS |
| evilbetty | more-watt-resistors |
| evilbetty | or chinese crap |
| evilbetty | they're probably 1W or so, maybe more |
| ohsix | wire wound resistors? |
| Mr_Sheesh | Or maybe older carbon composition resistors? |
| ohsix | they have a not official common name that doesn't help with what they are |
| evilbetty | those are generally brown but shiny |
| medfly | too many weird looking resistors |
| medfly | I'll take only the ones that look familiar |
| evilbetty | ol |
| evilbetty | just look at the color code |
| evilbetty | i also have brown and green resistors between my blue ones |
| medfly | I'm just curious. I cant use them cause the wires are too dang big |
| Mr_Sheesh | Oh noes, a resistor racist :P I have a friend who is so color blind it's not funny, he has a TOUGH time with the color code |
| medfly | so probably manny many watts |
| nnumerals | lol @ Mr_Sheesh |
| Mr_Sheesh | Sounds like high wattage resistors ya |
| ohsix | heh when did vishay buy dale |
| evilbetty | get him a dmm |
| medfly | it's just as much work to use a meter |
| Mr_Sheesh | He has one, but keeps wanting me to read the in-circuit resistors in circuits he's trying to fix |
| evilbetty | invent him a device |
| Mr_Sheesh | and he gets some WEIRD ones |
| evilbetty | a resistor value detecting camera |
| evilbetty | does he measure them in circuit? |
| raffahacks | I opened the converter, and an hdmi pin was disconnected.. |
| raffahacks | Guess which one? |
| Mr_Sheesh | I need a mini portal thing that can just pop the resistor free, measure it, pop it back in place. No, he knows not to rely on those values; He's a good soldering tech but not an EE at ALL |
| evilbetty | the hdmi one |
| Mr_Sheesh | power or ground? |
| raffahacks | The RED one! |
| jacekowski | oh no |
| evilbetty | its gonna explode in your face |
| jacekowski | cut the green one quickly |
| evilbetty | the red one is the wire for porno |
| Mr_Sheesh | LOL |
| medfly | can I just shove this resistor into this multimeter or is that too ghetto |
| evilbetty | yes and no |
| medfly | fuck it, I'll google a color code thing |
| evilbetty | if you shove it in, hold it in place with a finger touching both legs you're altering the resistanc :p |
| Mr_Sheesh | they have ATmega 328-based devices on ebay now, $20 or less - that measure L C R transistors Diodes FETs etc., pretty interesting, I may get one |
| evilbetty | i bet you can find the code for free for an AVR |
| blown | where's flea |
| nnumerals | Mr_Sheesh: link |
| raffahacks | Is the red pin in hdmi something else, or does it mean it isn't powered? |
| evilbetty | it means that happened to use a red wire |
| evilbetty | it does not mean anything else as long as you dont give meaningful info |
| Mr_Sheesh | nnumerals - http://www.ebay.com/itm/271594280462 is one |
| nnumerals | iigh |
| raffahacks | evilbetty: like? |
| evilbetty | like a pic, or a mention of where the red wire was once connected |
| FreezingCold | man hearing my alarms felt like a bag of bricks being dropped on my head |
| medfly | what's the point of having a cap on a dc source? |
| medfly | is that absolutely necessary? |
| raffahacks | There was seeedstudio written on it |
| ohsix | it has a lower esr! |
| medfly | (I can't find a cap) |
| evilbetty | as buffer for current draws, to remove AC on top of the DC, .. |
| raffahacks | I will send a picture later |
| Viper-7 | medfly: usually to reduce noise, often not *required* |
| Viper-7 | some dc is less dc than others :P |
| medfly | ok good |
| evilbetty | actually $15 isnt that bad for a board with a zif socket and lcd display i guess :pp |
| medfly | wanna power this LM339N thing |
| medfly | it's a comparator |
| raffahacks | I can say it was black, it had a hdmi and a vga and the hdmi was covered with (fake?) gold |
| evilbetty | you need at least a 100nF cap as close as possible to the IC |
| medfly | what |
| evilbetty | decoupling cap, google it |
| Viper-7 | meh, noisy in, noisy out |
| raffahacks | Viper-7: do you own viper-7.com? |
| Viper-7 | raffahacks: yeah |
| evilbetty | i have a domain that expires in 2 days :p |
| evilbetty | im gonna let it expire tho |
| raffahacks | Your codepad is very used then! |
| evilbetty | i removed all mailboxes and content like 2y ago |
| medfly | I want to know if something is within X and X+0.01V, but X could be anything for all I care |
| medfly | so I guess I need a cap |
| Viper-7 | raffahacks: haha cheers ;) glad you like it :) |
| raffahacks | Evilbetty: which is your website? |
| evilbetty | 0.01v? meh |
| evilbetty | http:/str0.be |
| evilbetty | with an extra / |
| fbs | woo nginx |
| fbs | dat hipster |
| raffahacks | So you will have a visitor this year |
| evilbetty | http://light.str0.be/la.png for the actual content :p |
| ohsix | isn't it the hipster that calls it out |
| evilbetty | i used to use cherokee webserver |
| fbs | ok u got me |
| raffahacks | 0001ACTION prepares a flame shield0001 |
| Viper-7 | medfly: 10mV isnt much, you'd probably want some kind of cap there :/ but try without if you have to, no raptors will attack you :P |
| ohsix | i heard you had some sort of server that spoke http |
| evilbetty | thats weird |
| evilbetty | i rarely heard servers speak |
| medfly | frankly, if I could consistently tell if it's at some voltage, I don't need the second comparison |
| Viper-7 | medfly: if the thing generating the signal voltage is using the same supply as the comparator, its less of an issue too |
| raffahacks | Viper-7, are you a web dev? |
| Viper-7 | used to be |
| raffahacks | Server side? |
| Viper-7 | of course |
| Viper-7 | and server clustering and such |
| medfly | so I have 3 10uF caps, 1uF, 2.2uF.. |
| Viper-7 | medfly: 1uF will do for a start |
| evilbetty | 10µF at board power input and 100nF close to the IC |
| evilbetty | im sticking to that 100nF :p |
| medfly | I could stick ultiple of 'e |
| medfly | 'em |
| blown | maggot drive |
| Viper-7 | a smaller one would be better |
| medfly | smaller |
| medfly | ok |
| blown | medfly: tell me some more about your breadboard |
| medfly | so look for a non electrolytic? |
| raffahacks | Can you explain me how does a domain registration work? I have a heliohost subdomain, and i want to register it on eu.org |
| Viper-7 | any little ceramic or such you have |
| Viper-7 | yeah |
| evilbetty | 50nF 220nF, something ceramic (not an elcap) thats around 100nF |
| fbs | eu.org? |
| raffahacks | It's a cute registrar |
| evilbetty | .eu.org is from the 90s :p they accept email |
| raffahacks | Free domain.eu.org |
| fbs | you go to a registrar that has eu.org and give them a stack of cash |
| fbs | they give you the domain |
| evilbetty | my advice is if you dont want to buy a domain pick a fun one from one of the thousands of domains on afraid.org |
| Viper-7 | raffahacks: well theres two parts, your registrar (who controls the name), and your DNS hosting (which controls which name points to which server, subdomains and such) |
| medfly | there's this small thing that reads '103m' what does that mean |
| raffahacks | Luckily I'm european :) |
| Viper-7 | the migration process is usually to setup the DNS hosting on your new provider, with whatever records you want |
| ohsix | how does the internet work |
| evilbetty | 103 = 10nF |
| evilbetty | m should be the % error |
| medfly | ah |
| medfly | as in |
| evilbetty | 103 = 10 + 3 extra zeros pF |
| medfly | 10^(-3) uF? |
| raffahacks | Viper-7: listening |
| medfly | oh |
| medfly | ok |
| evilbetty | 104 would be 10 0000 pF so 100nF |
| Viper-7 | then edit your old domain at the registrar, pointing it to the new DNS servers |
| medfly | so 10nF and 10uF is good? |
| Viper-7 | making your new DNS server live |
| ohsix | raffahacks: can you have him tell you about the internet in private |
| evilbetty | 471 would be 470 and 470 would be 47 (thats the misleading one) |
| raffahacks | Eu.org asks me for 2 main nameservers |
| Viper-7 | then signup for the domain at the new provider, letting them handle transition of the name between registrars, and have them use the new DNS service they provide when its done |
| medfly | just as a dc thing |
| evilbetty | 10nF may be a tad small for decoupling but better than nothing |
| Viper-7 | yes, a dns hosting provider should give you multiple dns server addresses |
| medfly | 10nF + something else ? |
| medfly | I have 1uF |
| Viper-7 | medfly: 104 (100nf) would be ideal |
| raffahacks | ohsix, sorry, ok |
| evilbetty | raffahacks: if you dont know how to use your own nameservers i really advice you afraid.org, where you can just add your records to their nameservers |
| Viper-7 | but 103 + 1uF would be a huge improvement over nothing :P |
| evilbetty | like i said earlier, the larger electrocap at the boards power input |
| ohsix | raffahacks: it's ok, it's just the two of you and it's not electronics is all, and i'm just some guy |
| evilbetty | or wherever |
| FreezingCold | if I have two fractions on either side, can I flip both of them? Like 1/A +1/B = 1/C |
| evilbetty | and the nF ones close to the ICs |
| FreezingCold | Can I make that B + A = C |
| Viper-7 | raffahacks: dont mind ohsix, he had some sand surgically grafted to his vagina back in the 80s and its getting real sore |
| FreezingCold | wrong chan |
| ohsix | FreezingCold: heh |
| Mr_Sheesh | I use 104's (100nF) a lot on many boards, with 1-10uF caps here and there, it is a PAIN to trace down a decoupling problem, and caps are cheap; If you're making 10000000's of something, decrease the caps last so you can develop without power issues :P |
| fbs | FreezingCold: that would be 1/(1/a+1/b) = c |
| evilbetty | like china |
| evilbetty | remove decoupling caps until it just works in lab conditions : |
| evilbetty | but not at home anymore :p |
| Viper-7 | medfly: yeah, common practice is basically to put a 100nF cap next to everything that uses power :P |
| ohsix | Viper-7: lets talk about the diets of cats instead |
| Viper-7 | grab a bunch of those when you can |
| FreezingCold | fbs: heh how does the 1/ get on top there? |
| Viper-7 | ohsix: how do you make a siren? |
| ohsix | FreezingCold: 1/c |
| medfly | righto |
| fbs | FreezingCold: 1/x on both sides |
| medfly | so now I need somethin gto supply DC |
| medfly | I think that having a power supply for this might be overkill |
| Solarlux | Hello anyone knows WHats name of surface mapping technology industral robotics? |
| Viper-7 | ohsix: tie a cat up by it's tail to a clothes line and whack it with a cricket bat |
| evilbetty | this is what happens if you didnt plan decoupling caps in your design :p http://cdn.instructables.com/F4B/M500/FTY4C7O5/F4BM500FTY4C7O5.MEDIUM.jpg |
| FreezingCold | fbs: Thanks |
| medfly | dc supply |
| medfly | rather |
| ohsix | it is not often i see a math questoin i can answer myself!!1olol |
| evilbetty | but seriously, look at this: http://nw2s.net/wp-content/uploads/2014/05/a006-decouple.jpg every IC a decoupling cap, and they dont do it for prettiness |
| Solarlux | Hello Viper and evilbetty |
| evilbetty | its there for a reason |
| evilbetty | allo |
| Viper-7 | Solarlux: hi, and no idea :P |
| Solarlux | Like industral robots what map parts on surface |
| ohsix | i've left in decoupling caps for prettiness |
| evilbetty | professionality :p |
| medfly | what's a less bulky way to get DC than to use a DC supply |
| medfly | do I get a battery.. |
| evilbetty | anyway point is, every once in a while we have ppl trying to avoid them |
| evilbetty | dont do it :p |
| fbs | FreezingCold: you could jus fill in number |
| ohsix | wanting things to be symmetrical when they nearly are has wasted a lot of my life |
| smeding | evilbetty: to the point where, in the days of 74xx series logic, you had those sockets with caps built in :) |
| ohsix | or did you |
| evilbetty | i know |
| FreezingCold | medfly: 18650 cell :p |
| ohsix | they did have standard power pin positions |
| fbs | FreezingCold: like 1/3+1/4 = 7/12, with your answer you get 3+4 = 12/7 |
| Viper-7 | if decoupling caps were so important, we'd have like a 10 ohm or more resistor before every cap + IC |
| medfly | these two things are 1 mega ohm :3 |
| evilbetty | nothing sexy like axial ceramic caps |
| Mr_Sheesh | Also, use nice THICK power traces if you do a 1 or 2 layer PC board, don't make a 12'x12' PC board with 12 mil traces 2 yards long for 5VDC and expect it to freaking WORK right. I've seen that. It was bad LOL |
| Viper-7 | normally as a filter, they're just using the trace resistance :/ |
| medfly | actually, do I even need resistors.. |
| raffahacks | FreezingCold: type fake ultrafire on google pics and you will be scared for those 10 cells you bought yesterday for 15usd.. :) |
| Viper-7 | medfly: no, they're a myth invented by 'the man' to waste money in circuits |
| medfly | I do not :D |
| FreezingCold | raffahacks: lol |
| medfly | I just have this trigger signal and I wish I could have like a pulsey thingie whenever it crosses a certain voltage |
| raffahacks | Have you seen? |
| medfly | the signal is a ramp |
| evilbetty | lol |
| evilbetty | that reminds me of those trustfire flame batteries |
| evilbetty | how much fire can you have in 1 liio |
| Viper-7 | pulsey thingie heh |
| Viper-7 | medfly: why do you need a pulse? |
| evilbetty | pulse jet |
| medfly | Viper-7: want it to be the trigger for another supply |
| medfly | I'm not sure what the comparator will output |
| Viper-7 | but. is a rising edge not enough? |
| evilbetty | a 0 or 1 |
| Viper-7 | you need both a rising and falling edge? |
| medfly | Viper-7: it's a ramp I want to take a middle value.. |
| Viper-7 | yes |
| medfly | do you think I should take the start? |
| Viper-7 | and when you hit the desired value |
| Viper-7 | the comparator output will turn on, and stay on |
| FreezingCold | raffahacks: yep |
| Viper-7 | until the value drops below the desired point |
| medfly | Viper-7: what are we discussing |
| medfly | yes that is exactly what I want |
| Viper-7 | if you want to turn that solid on output into a pulse, you'll need another chip after the comparator |
| Viper-7 | or a change in design |
| blown | 0001ACTION waves to smeding0001 |
| ohsix | where we're going we won't be needing resistors |
| medfly | rising edge is fine |
| medfly | ohsix: correct :P |
| Viper-7 | ok, well job done then :P |
| Viper-7 | find or make a reference voltage |
| medfly | it outputs 36V, wtf |
| medfly | what do I do with that / |
| Viper-7 | what does? |
| ohsix | put it on your junk |
| medfly | oh that's absolute maximum |
| Viper-7 | heh yeah |
| medfly | I wanna see what the comparator will output |
| medfly | 36V is probably risking damaging my equipment :[ |
| Viper-7 | its an open collector output |
| Viper-7 | its either connected to ground or left floating |
| Viper-7 | you can use a pull-up resistor to whatever signal level you want |
| medfly | so you're saying try to make sense of what the device actually does eh |
| Viper-7 | with reason (try not to exceed Vsupply of the comparator) |
| fbs | as long as its below maximum |
| medfly | schematic makes it looks like it won't exceed Vcc |
| medfly | but I'm scared about damaging things.. |
| medfly | maybe I shouldn't be, this signal source is kinda meh |
| fbs | stop being a pussy |
| Viper-7 | for the input voltage thats fine |
| Viper-7 | use a voltage divider |
| medfly | fbs: dude, shit here is expensive |
| fbs | so? |
| ohsix | heh |
| medfly | no way it'll exceed supply voltage right? |
| fbs | if it burns you repair it |
| medfly | fbs: no |
| Viper-7 | whats 'it' ? |
| medfly | if it burns I never come back here :P |
| medfly | 'we can't trust you with this equipment' |
| ohsix | if it burns fbs is volunteering to pay for it |
| Viper-7 | the input voltage? which you're sourcing from god knows where? maybe. |
| raffahacks | evilbetty: trustfire flames aren't too bad, i've read.. |
| FreezingCold | raffahacks: http://www.aliexpress.com/item/Lowest-Price-New-1PCS-5V-Mini-USB-1A-Lithium-Battery-Charging-Board-Charger-Module-b7-TK0458/1834351723.html |
| medfly | it's a common emitter tho |
| medfly | at the output stage |
| medfly | dammit |
| medfly | Y U NO LOGICS |
| raffahacks | I was thinking of buying 4 |
| medfly | it might output more than the power supply voltage! |
| Viper-7 | 0001ACTION blinks0001 |
| FreezingCold | raffahacks: I bought 4 :D |
| medfly | I guess I can use a voltage divider |
| raffahacks | FreezingCold: are they bad? |
| medfly | before checking whether it does that |
| Viper-7 | medfly: you're worried about the comparator output being higher than the supply voltage? o.O |
| medfly | and then checking whether it does that |
| Viper-7 | that wont happen. |
| medfly | Viper-7: yes |
| medfly | Viper-7: I am worried |
| medfly | yeah, it'll saturate.. hopefully? |
| FreezingCold | raffahacks: I dunno, I assume I'm going to burn out one or two being an idiot. I want to use them to 'recover' cell phone batteries that drop below 3.6V |
| medfly | the input might be higher than the supply voltage.. literally nothing I'm supplying is higher than it could handle. but I should check |
| Viper-7 | medfly: you should divide the input to be *always* within Vsupply and ground of the comparator |
| medfly | why? |
| ohsix | so that concern you have goes away |
| medfly | I could use a diode I guess |
| medfly | so ghetto |
| Viper-7 | but unless you do something really bad there, the output will always just be open collector, so either grounded or not - add your own pull-up resistor to the Vsupply |
| Viper-7 | medfly: use two resistors. a voltage divider |
| raffahacks | Is it real that every laptop battery contains many good 18650s? |
| ohsix | there's a butterfly called 'purple brown-eye' |
| medfly | woo hoo |
| fbs | raffahacks: no |
| medfly | not only is this thing a diode |
| medfly | it's also a zener diode! |
| medfly | :D |
| Viper-7 | medfly: what voltage tho? :P |
| ohsix | raffahacks: a 6 cell battery is common, they're not 18650s but a smaller one, i think |
| medfly | 5.6V |
| medfly | first I will check what output I need to give |
| raffahacks | I mean old laptops |
| raffahacks | With thick batteries |
| ohsix | google shows tons of 18650s |
| ohsix | eh, they might even be nicds, nimh |
| ohsix | google knows what laptop i have and is showing mostly batteries for mine, heh |
| medfly | I can't believe I manage to get things done with how lazily I'm working |
| raffahacks | Omg NO! |
| raffahacks | I HATE NiCds |
| ohsix | man the x61 battery looks tarded |
| ohsix | cadmium tastes great, what's to hate |
| raffahacks | Their ghost is following me! |
| raffahacks | A car battery sized nicd will contain 1ah |
| fbs | atleaest you have one follower |
| ixxie | yo |
| ixxie | any discrete time dynamical systems wizards in the house? |
| ohsix | that guy on youtube |
| ohsix | what is your question? |
| raffahacks | And a CAR-sized one, 1.2v 3ah |
| blown | the mos fet |
| raffahacks | They are big, heavy, bad, have memory effect, small volts and amps. |
| medfly | damn this stupid manual for not mentioning maximum voltage |
| ohsix | what manual? |
| raffahacks | Do you know now why i have cadmium? |
| medfly | Agilent 33220A waveform generator |
| medfly | that's where my output goes :P |
| medfly | it says I should input TTL levels |
| FreezingCold | man university is weird. We're learning how to calculate all these fun voltage and current rules that get really complex, yet we haven't touched a DMM in real life yet |
| FreezingCold | that seems so.. sad :( |
| FreezingCold | by 'we' I mean the rest of the class |
| FreezingCold | me and my trusty UNI-T have a good relationship |
| medfly | my university ha you go through 2 years of gruelling mathematics and physics classes before the first electronics lab |
| medfly | if it can handle TTL surely it can handle an input which is at most 5.6V |
| medfly | right? right? |
| FreezingCold | medfly: that's sad, playing with the stuff is the majority of the fun! |
| ohsix | FreezingCold: heh, they aren't doing anything unusual |
| medfly | right. |
| ohsix | what use is a meter for something if you don't know if that value is correct? |
| FreezingCold | ohsix: I know, I was told there wasn't much hands on in university, but I was surprised by it stil |
| medfly | I'm at university right now looking through a pile of unsorted resistors some of which are soldered together |
| medfly | pretty hands on |
| FreezingCold | third year IIRC? |
| ohsix | by the time you know what you're doing, they'll have stuff to do |
| ohsix | you'll have to write a thesis and shit brah |
| ohsix | On some rare x86 targets, setjmp doesn't save the registers in all circumstances. In those cases, GCC doesn't allocate any variables in registers unless they are marked register. |
| ohsix | wat u say |
| tlvb | After unpacking (after a move) my i2c interfaced light sensor (tsl2561+breakout board) I get no sensor readings (all zeroes all the time), with code that I know to have previously worked, I have tried switching out the mcu to no avail as well, is there anything left but to consider the sensor/breakout board borked and getting a new one (or considering a different sensor)? |
| Celerity_ | 0001ACTION is miffed about paypal not working with debit cards due to government regulations0001 |
| ohsix | man there are so many things |
| ohsix | tlvb: does the initialization sequence or any register you can read actually work? |
| Celerity_ | 0001ACTION feels chained without ebay0001 |
| ohsix | Celerity: argentina? |
| Celerity | ohsix: Worse, India |
| ixxie | ohsix my question is regarding the use of eigenvalues to identify stability in non-linear systems |
| Celerity | wtf Government! |
| anton02 | every time i log on i have to ghost my user. wonder why |
| ohsix | oh, similar things are going on in argentina |
| ohsix | ixxie: go for it |
| Celerity | but they have hyperinflation crisis, here we're chill about the economy |
| anton02 | do you guys prefer mica or niobium capacitors |
| ohsix | anton02: an irc bot from bulgaria seems to be using the name when you aren't |
| ixxie | so when one linearizes the system and finds the eigenvalues, one identifies stability of the equilibrium locally |
| ixxie | but it can happen that this doesn't quite fit the global story |
| FreezingCold | anton02: boooooo |
| anton02 | ohsix: inside this channel? |
| ixxie | say - the leading eigenvalue is outside the unit circle but stable cycles occur |
| ixxie | right? |
| Celerity | And shit is literally triple the cost on local websites as compared to ebay. the 10DOF IMU on ebay is ~$8.5, on a local site it's closer to ~$22 |
| ohsix | ixxie: https://www.youtube.com/user/ControlLectures/videos :< |
| ohsix | anton02: no, you can use /whowas nick and the irc server will tell you about them |
| ohsix | ixxie: right |
| Celerity | if you don't 'believe' in credit cards this country just killed innovation. |
| ohsix | ixxie: but that is like the only question i can probably answer heh |
| ohsix | hmmm |
| ohsix | brian douglas might not have been the thing i was reading/watching about discrete time stuff |
| tlvb | ohsix: I have little experience with i2c communication, so I don't exactly know what to check for, the device id register have never read correctly (if my interpretation of the data is correct), but given that I got the sensor to get me data, and that it was a sparkfun breakout I figured that was a minor/non-issue |
| Celerity | The Reserve Bank of India issued a blanket 'No debit cards shall be allowed for international online transactions.. ever' |
| ixxie | ohsix so I should ignore the link? xD |
| Celerity | how the hell am I supposed to buy parts! |
| ohsix | tlvb: ah that's a bummer, the sensor could be damaged or something, reading a register rules out the connection being bad |
| ohsix | ixxie: i'm just not sure what video it may have been, they aren't sorted into discrete and continuous, he covers both when it is notable |
| ohsix | all the root locus stuff is that, i think |
| ohsix | The root locus method can also be used for the analysis of sampled data systems by computing the root locus in the z-plane, the discrete counterpart of the s-plane. |
| darsie | morgen |
| ohsix | yep |
| ixxie | hmmm this control systems language is like a whole other universe for me xD |
| ixxie | I come from a biomathematics background |
| ohsix | nice |
| ohsix | that's one of the reasons youtube is awesome |
| ohsix | mit open courseware has stuff on systems, with video lectures; i haven't watched any of those but the format makes them generally more comprehensive if you have the time to start from the beginning |
| tlvb | ohsix: well this was from before it stopped working, I might not actually do sufficient checks of anything but the adc data in the current code rev..I should probably do that..However given that I have ruled out glitchy connections to the board, and that i have tried known-to-be-working code..hm I guess there is a slight chance of a broken pad/trace or something else that's potentially fixable if I |
| tlvb | get no data /at all/ |
| ohsix | tlvb: i'm paralyzed by the sheer numbers of things it could be |
| ohsix | since the code and stuff are ~the same from when it worked, i'd have to check the link, then the initialization and making sure the device was working from a communication standpoint |
| ohsix | starting over fresh and just trying to read the chipid might be worth doing |
| tlvb | perhaps it's not as obvious as I think it is that when I write 'previously working code' I mean a complete firmware for the interfacing microcontroller, as in everything sent to and received from the sensor from power up and onward |
| Celerity | guys, is there a place where I can buy shit using google wallet? |
| ohsix | google play |
| ohsix | and nfc stuff |
| ohsix | hmmmmmmmmmm |
| medfly | FreezingCold: last year, doing final project |
| ohsix | anything using google checkout |
| Celerity | no i mean electronics |
| Celerity | it seems the cheapest place is ebay |
| drac_boy | hi |
| nofxx__ | wtf is a 'fast fuse' ? SSR guy saying I should use 'fast fuse' instead of a normal fuse |
| evilbetty | one that trips fast i guess |
| nofxx__ | not sure its 'fast fuse' in english. |
| nofxx__ | literal translation |
| jpa- | nofxx__: yes, it is |
| evilbetty | http://electronics.stackexchange.com/questions/25055/slow-blow-vs-fast-acting-fuse |
| jpa- | 'slow fuse' is the other alternative |
| evilbetty | slow blow :p |
| medfly | this isngular normal wire I found will function as 5 different wires in the circuit :P |
| medfly | 0001ACTION chops it up more0001 |
| nofxx__ | thanks, results was all about fireworks hehe |
| zap0 | a wet string is a fast blow fuse, when compared with a piece of train track. |
| drac_boy | is it ever unusual or actually sometimes normal to for example have a gigabit controller being paired with a fast ethernet phy? |
| evilbetty | woop |
| ohsix | nofxx__: fast is fast, slow will handle overcurrents and stuff for a while before failing |
| evilbetty | they wanna cut towns off the grid during winter |
| evilbetty | govt provided a plan, but its uneadable (probably on purpose) |
| evilbetty | and their govt site crashed from the visitors |
| drac_boy | heh.doesn't sound very good evilbetty? :) |
| evilbetty | they wanna do it between 17 and 19h |
| evilbetty | just when you wanna eat |
| nofxx__ | ohsix, I see.. darn fluke's expensive fuse should be fast.. I've removed quickly after I realized probe was on A |
| nofxx__ | not a chance =P |
| ohsix | what is it supposed to do? save money? |
| evilbetty | save energy |
| ohsix | nofxx__: yea it is to protect sensitive equipment |
| ohsix | is most energy used at dinner time or something? |
| evilbetty | because of some sabotage in one of our nuclear plants |
| ohsix | nofxx__: other stuff is sensitive too, but might have peak inrush current or something very temporary and you don't want the fuse to go because of that |
| evilbetty | in winter the peak is around 17h when it gets dark and ppl come hom from work yes |
| drac_boy | anyway one other thing tho..I forgot the name for some reason but what is it called if you for example had only one single pcie lane but wanted to use two or more devices on it tho? (which means some sort of splitting/sharing yeah) |
| evilbetty | ah well |
| evilbetty | i guess ill need a UPS for my modem :p |
| ohsix | drac_boy: another bus |
| ohsix | like, a bus extension |
| Jazzdude | evilbetty: may I ask where that is? |
| ohsix | the bus extender shows up as one pci device and keeps track of the BARs/cache/whatever of the stuff behind it |
| nofxx__ | evilbetty, building a DC UPS, very nice idea, no stupid invertion, not much thing on it |
| nofxx__ | lets make an open hardware |
| evilbetty | .be |
| nofxx__ | plug modem/wifi, all one (with laptops and tablets) needs |
| evilbetty | $10 250Ah usb batter pack :p |
| Jazzdude | evilbetty: and one of your *nuclear* power plants has been sabotaged and there's nothing in the news all over europe?! |
| nofxx__ | nah, needs to be more fun, like you can plug a solar panel hehe |
| ohsix | evilbetty: seems like it would be huge news if someone sabotaged a power plant, nevermind a nuclear one |
| drac_boy | ohsix.mm bus extension..guess that name makes sense |
| drac_boy | ty anyway.just trying to sort out how to get around this cpu having only one single pcie lane to use :-s |
| evilbetty | it was huge news |
| evilbetty | but it may be a lie |
| ohsix | heh they call them switches |
| evilbetty | for all we know they spread news about sabotage just to prepare us for power autages for putting money in their pocket |
| ohsix | i specifically avoided calling them that because i wasn't sure |
| ohsix | eh |
| ohsix | you aren't in the power business to line your pockets |
| evilbetty | here they are |
| ohsix | drac_boy: it will be expensive and slow to do it, what do you want more pci express devices for? |
| evilbetty | in fact when they released the pocket filling energy monopoly over 50% of customers left the main power company |
| medfly | so,there are batteries, but they are 9v |
| ohsix | you have a choice of power suppliers? |
| medfly | am I insane for thinking of using two 1Mohm resistors as a voltage divider |
| medfly | yes |
| medfly | I don't think you understand how both over and under equipped this place is :P |
| medfly | well, I can find two identical 200 ohm things |
| ohsix | medfly: yea a 1mohm resistor divider will be very noisy and the actual division part will suck |
| medfly | wouldn't I need a high power resistor if I connect it directly to battery? |
| medfly | I just need like, 5v ish |
| medfly | there's 200 ohm resistors I can take |
| medfly | is that too low |
| ohsix | you need a regulator to do that if the supply is unregulated |
| evilbetty | lol |
| Yotson | ohsix, here in NL the electricity and the wires to transport it are owned by different companies. So yeah, you can pick any supplier you want. (not sure about BE) |
| evilbetty | LG employees damaged samsung devices on ppurpose in some mall |
| anton02 | does it matter what type of capacitor you connect to the Cboost pin on SMPSs |
| drac_boy | ohsix because I'll likely need one onboard and one minipcie at the minimum . not sure if there'll be more or not but 2-3 lanes being required seem most likely |
| ohsix | Yotson: yea but why would you ever pick the one that was't the lowest price or something |
| ohsix | drac_boy: right, you have no alternative, usb or anything? |
| Yotson | ohsix, good point. But they 'diversify' their offerings. green, cheap, made by gnomes, .. you can get the precise elec. you want. .. XD |
| xata | Hello |
| medfly | what can I connect to a 9V battery without damaging it |
| medfly | fuck it I'm going to get a power supply like a normal person |
| medfly | dc supply |
| drac_boy | ohsix.you'll have to put a pcie-usb controller unless you wanted to use one of these non-pci counterpart if any exists (I only know of a few for ethernet alone atm tho) |
| xata | Got troubles with NAND SLC. I am trying to make a read-write access to NAND using STM32F1. Identification data can be read ok, But when i try to read something from memory banks it sends 0xBF instead of 0xFF. Also if i try writing something to NAND, and than readt that byte it is still 0xBF. What this can be? Hardware failure? Timing troubles? Something i don't know about NAND? |
| mr_boo | xata: what do you mean with 'NAND'? |
| mr_boo | xata: ah it's a flash memory |
| xata | This could be failure of bit 6, but it is ok, and is working ok when in identification data stage |
| xata | Yup, nand flash, like used to be used in ald usb flashdrives |
| mr_boo | xata: check supply voltages. data can be corrupted if too low voltage is applied |
| xata | mr_boo: it is standart 3.3, straight from uC. Maybe it could be overcurrent, gotta check dat |
| mr_boo | xata: what uc btw? |
| Evidlo | So I just bought an ESR meter. Anyone have a good rule of thumb for how far the cap should be off it's value on the ESR table? |
| evilbetty | a few centimeters |
| Evidlo | Percentage |
| mr_boo | xata: is there a way to be sure what the flash memory data is? can it be reset to just zeroes or ones? |
| xata | mr_boo: no, it can't be because write does not work, i have to chec aybe there is hardware way to blank the memory. under uC i mean stm32f1 on development board. anyway power id ok, checked with oscilloscope |
| Solarlux | Gear lift power |
| Solarlux | How can i say it in other words? |
| evilbetty | use the force |
| anton02 | By recommended they probably mean minimum recommended given the following, right? A capacitor must be connected from pin 3 to the switch output, pin 1. This capacitor boosts the gate drive to the |
| anton02 | internal MOSFET above Vin to fully turn it ON. This minimizes conduction losses in the power switch to maintain |
| anton02 | high efficiency. The recommended value for C Boost is 0.01.uF |
| Solarlux | For example how much power need to lift something with gear |
| Solarlux | energy maded by gear |
| nofxx__ | Solarlux, it's a ratio, you won't find nothing on the stone |
| nofxx__ | you can lift 2t with this baby http://www.casadoconstrutor.com.br/uploads/equipamento/talha-manual-1-tonelada.jpg |
| nofxx__ | and not even sweat heh |
| drac_boy | sorry but remind me again what one normally does with SMBus? |
| nofxx__ | gears are the mechanical op amps |
| Solarlux | Thanks |
| Solarlux | I look at your given pic nofxx_ |
| SpeedEvil | nofxx__: gears are mechanical transformers. |
| SpeedEvil | opamps are more pressure controled valves. |
| JFK911 | drac_boy: diddle disk backplanes |
| SpeedEvil | Or a couple of clutches |
| Solarlux | http://youtu.be/kbUfitBQZW8 for example i make gear mechanisms what need driven with electric motor |
| drac_boy | jfk911..umm..? |
| Solarlux | What calculations works work with gears and power and speed of gears? |
| evilbetty | bah disgusting ppl here |
| SpeedEvil | Speed of rotation of a gear meshing with another gear is simply the relative diameters of the two gears. |
| Solarlux | Ok |
| evilbetty | what about the number of teeth? |
| SpeedEvil | So if you have a gear with 10cm diameter meshing with one with 5cm - the revolutions will be twice on the 5cm gear |
| Solarlux | rpm |
| SpeedEvil | And the torque is half on the 5cm gear |
| Solarlux | 10+5cm diameter gears |
| Solarlux | 2 gears one 10 and another 5 cm |
| Solarlux | ratio 1:2 |
| Solarlux | ? |
| evilbetty | i know for rc helis the number of teeth matter |
| Solarlux | 2:1? |
| SpeedEvil | The number of teeth don't matter |
| SpeedEvil | Solarlux: work it out - it's just the consequence that the edges don't slip |
| evilbetty | bah not again |
| Solarlux | Ok |
| mr_boo | is it hard to implement S/PDIF output in software on an Arduino? |
| SpeedEvil | probably impossible |
| evilbetty | freenode is depressing lately, both its stability and its users :p |
| Solarlux | I want connect electric knowledge with mechanical knowledge |
| drac_boy | mr_boo depends how big of a stream you want but for simple matters it should already be possible with most 16bit cpus |
| mr_boo | drac_boy: if i only could find a library for that |
| drac_boy | big surround may be ofc easier with a nice 32bit |
| mr_boo | drac_boy: btw have you ever worked with serial sigma-delta audio DACs? |
| drac_boy | mm anyway about me asking about displayport..well.its because I'm not sure if I'm able to find the right place (VESA's own limited slideshow files says almost nothing anyway) but does anyone even know if its possible to use displayport with only one single video lane? (its just a small 720p screen so) |
| drac_boy | mr_boo nope sorry |
| Jazzdude | mr_boo: do you have a question about using serial dacs? |
| R0b0t1 | https://www.youtube.com/watch?v=vAYEaIrDok8 |
| R0b0t1 | not at all relevant, but yeah. |
| mr_boo | Jazzdude: yeah i wonder if the master clock _must_ be synced with the word clock |
| Jazzdude | mr_boo: that depends on the DAC. Some require synching, some encourage synching and some do their own PLL business |
| davesleep | zup. how do i test if a speaker driver is broken |
| davesleep | one minute. actually |
| mr_boo | Jazzdude: i'm not getting anything from my CS4382 DAC from Cirrus Logic |
| Jazzdude | mr_boo: datasheet url? |
| davesleep | i get a beep when i test - driver + |
| mr_boo | Jazzdude: http://www.cirrus.com/jp/pubs/proDatasheet/CS4382_F2.pdf |
| Jazzdude | ok, so what do you feed it? |
| davesleep | okay. no i dont |
| jubei | Hello. I want to connect 4 potentiometers to the arduino. I'm wondering how I should wire the pots' 3rd pin, the VCC input. I should take from arduino's VCC and put that to all 4 pots in parallel? |
| davesleep | right. if i test using my multimeter, a speaker driver from + to - |
| mr_boo | Jazzdude: i was trying with a master clock from a PWM output and i'm using 32kHz samplerate |
| davesleep | should i be getting a beep? |
| Celerity | my 2004's 120gb IDE finally gave up the ghost. RIP. |
| Celerity | I think I may be able to only salvage the BLDC motor |
| R0b0t1 | heh |
| Celerity | everything else on the board seems to be custom parts with no easily available datasheet |
| Celerity | hi R0b0t1 ! |
| drac_boy | 2004? thats barely even much wear at all |
| R0b0t1 | yeah you usually can, but they're not good for much |
| R0b0t1 | fun to spin though |
| mr_boo | Jazzdude: i'm thinking it might go into mute mode and mute output due to poor master clock sync but that is a guess |
| Jazzdude | mr_boo: pwm? The master clock is several MHz. What kind of PWM are you driving that with? |
| mr_boo | Jazzdude: from Arduino Due and PWM freq is about 8.192MHz |
| drac_boy | celerity..yeah hdd pcbs are often very specific . even a batch from 2006 can be different enough to be incompatible with the earlier batch from eg 2002 in some cases |
| Celerity | drac_boy: this was an IDE used when I didn't know computer best practices such as never turning it off. I'd say he had a decent run. |
| mr_boo | Jazzdude: all i've got from it is a weak periodic noise |
| JyZyXEL | damn ikea wins again, no one told me i would be constantly hitting my knees a steel pipes when they sold me this office table |
| Celerity | The shiny platter is attractive but I don't know what I'll do with it |
| drac_boy | thats why failed-pcb-but-good-drive generally are only worth a specialized recovery if you really had only one copy of something mportant |
| drac_boy | celerity..umm what do you mean about 'best practices'? |
| davesleep | basically if my multimeter isnt picking up anything when i test the driver across the terminals |
| davesleep | it means the speaker driver is dead? |
| Celerity | nah, I'm good. It was almost failing so all data was pulled out long ago. |
| Jazzdude | mr_boo: section 6.6: The sample and LR clock must be derived from the master clock |
| R0b0t1 | Celerity: Heh, I had an uncle with a drive he never spun down. I think the power went out or something once and to spin it back up he had to open it and use his fingers |
| Jazzdude | mr_boo: you'll need proper clocking in any case if you expect good audio quality |
| R0b0t1 | still worked to get the data off though |
| Celerity | drac_boy: I've heard that computers/electronics in general live longer if you dont kill the power |
| mr_boo | Jazzdude: i haven't got any signal at all from it |
| drac_boy | celerity thats just hogwash tbh |
| Jazzdude | mr_boo: yes, that is because it cannot synch to your sample input |
| Celerity | R0b0t1: now, THAT is a champ |
| mr_boo | Jazzdude: but it may be broken |
| drac_boy | I actually got a 1.2gb hd that still works and its only had short power-on cycles |
| Jazzdude | mr_boo: I doubt it. I would be very surprised if you got this working with a PWM clock and a non-synchronized sample/LR clock |
| Jazzdude | mr_boo: do you derive the LR clock from the PWM clock? |
| R0b0t1 | drac_boy: It's probably true for disks, other stuff is suspect. But stuff with bad build quality is likely to have problems exacerbated by thermal cycling, which is why the myth persists. |
| R0b0t1 | It's not REALLY a myth, but it relies on someone having fucked up. |
| mr_boo | Jazzdude: i'd like to but don't know how to do that on an uc |
| R0b0t1 | (Do things properly and it's a non-issue.) |
| Jazzdude | mr_boo: a clock divider can be done by simply having a high performance counter running and taking the 9th bit output |
| Jazzdude | mr_boo: that will divide by exactly 256. Use that clock to drive the samples from your uC |
| drac_boy | r0b0t1..good point.I've generally never bought cheap-priced things ever for as long as I can recall. its silly how some people ask me why I'm spending so much money when in fact I'm likely spending A LOT LESS than they are with their short-sighted brains |
| drac_boy | not trying to offend anyone here ofc, just my own personal experience ^^ |
| mr_boo | Jazzdude: yeah and then a pin interrupt to feed a new sample. thanks |
| mr_boo | Jazzdude: you're the man |
| Jazzdude | mr_boo: but seriously, think about getting a proper clock. PWM is usually not very reliable for this |
| Jazzdude | mr_boo: with a clock generator IC this is very easy to do |
| Celerity | drac_boy: I'm too poor to be cheap :P /hi-five |
| R0b0t1 | drac_boy: Oh yeah definitely |
| g0z | drac__boy: get into arcade game collecting then you'll face that problem a lot :P |
| Celerity | Buy once, but buy well. |
| frimend | I agree with the idea of buying quality. |
| sexyboy | hey, can overvoltage be caused by a electric company guy on purpose? |
| frimend | But most of the time, not buying at all is even better. |
| sexyboy | i mean, is this in the guy power |
| Celerity | which is why regardless of wealth a toyota/honda//lexus/acura are the optimal cars |
| drac_boy | celerity..yeah its silly how for example person A could buy something for $4 then buy it again a few months later etc while person B buys something for $10 and keep it for more than a year |
| drac_boy | a bit oversimplified example but anyway ^^ |
| Celerity | drac_boy: That's the Samuel Vimes Boots Theory :P |
| sexyboy | anyone? |
| Jazzdude | mr_boo: also if you're using the arduino due, you should probably use direct port access instead of the pin read/write functions provided by the library. That will improve timing a lot |
| mr_boo | Jazzdude: doing that already |
| drac_boy | and celerity funny that you would mention cars . I actually have been working on several many toyota engines (have 3 of them myself personally) |
| frimend | sexyboy: They can do whaterver they want, they have the POWER! |
| frimend | ha ha ha |
| drac_boy | only got one single non-toyota engine and its a 'newer' vw non-turbo diesel block |
| sexyboy | frimend: bus seriously, would that guy be able to cause overvoltage in an apartment by doing something in the electricity box? |
| Celerity | drac_boy: working means? are you a mechanic? |
| mr_boo | Jazzdude: i'm using a timer interrupt to generate new samples hence the difficulty to obtain 256X that freq |
| Celerity | or is it your own |
| frimend | sexyboy: I would expect that some power company guys could do that, in some appartment blocks, with some electricity boxes. |
| flyback | CANUCK_boy |
| drac_boy | celerity bit of both basically |
| Celerity | ok |
| frimend | Under some circumstances, with certain modificaitons.. etc etc. |
| sexyboy | frimend: do you ever do not troll? |
| Celerity | I've got a friend who swears by VW |
| Celerity | he's got a Polo |
| frimend | sexyboy: You ask a impossible question, you get bad answer. |
| sexyboy | impossible? |
| drac_boy | celerity basically its more of a 'need a better engine in your old pickup? well if you can leave it here I could try have a look' sort of private sideline thing rather than an actual garage business |
| drac_boy | you follow me? |
| Celerity | ofcourse! |
| drac_boy | and as for vw..well.. |
| Celerity | japanese cars are cheap to run |
| Celerity | can't say that about vw here (india) |
| frimend | No car at all, is cheaper than a cheap car. |
| drac_boy | I do like the older jetta's and the real beetle (not that crappy front water-cooled engine one! hah) but thats as far as it goes with vw for me tho |
| frimend | Way cheaper. |
| Celerity | frimend: obviously |
| drac_boy | especially as they seem to lack any rwd-or-rwd/4wd chassis for most part |
| flyback | Celerity, did you lose a hd? |
| mr_boo | Jazzdude: btw do you think the DAC mutes the audio when it considers the master clock to be pooly synced with word clock? |
| mr_boo | Jazzdude: otherwise i should get poor audio quality at worst |
| frimend | I would like a new version of the CV2 to be made.. |
| Celerity | flyback: well, yeah. a 2004 120GB IDE Seagate |
| flyback | important data on it? |
| Celerity | nope |
| frimend | http://www.lowtechmagazine.com/2008/06/citroen-2cv.html |
| flyback | oh ok |
| Celerity | everything was out |
| frimend | Quality, simplicity. |
| frimend | Cars nowadays come with a gazillion extras. |
| flyback | save it and play with tmos if it still twitches |
| Celerity | We don't have many French cars here. |
| Jazzdude | mr_boo: it probably doesn't even start converting without a proper sync. But once it locks on, the clock quality has big influence on the audio quality. |
| Celerity | tmos, flyback ? |
| flyback | tmos is a hd os |
| Celerity | oh |
| flyback | you just need a ttl uart usb cable |
| drac_boy | celerity mind you its probably just me and the particular roads around here but I generally hate most fwd cars because of them being rather difficult to keep on the road in a literal sense |
| flyback | it's right off the jumper pins |
| Celerity | flyback: like the guy that installed Linux *on* his HD? |
| flyback | yeah I dunno about that |
| Celerity | drac_boy: ESP no go? |
| davesleep | can someone recommend me a brand of solder flux |
| davesleep | i keep buying bloody plumbers flux |
| drac_boy | celerity if you got some lead weight bags sitting next to the radiator . it probably could work . otherwise watch out |
| flyback | davesleep, NO NO NO |
| davesleep | yes. |
| davesleep | yes yes yes. |
| flyback | plumbers = acid = CANUCKED PCB |
| Celerity | lol |
| davesleep | loLL yeah i mean i know that |
| flyback | kester btw |
| davesleep | and i keep buying that sht by accident |
| flyback | you can get flux pens on ebay cheap |
| fbs | some spit works fine |
| flyback | the only thing that bites ass about flux pens is they are useless for hot touch up |
| davesleep | i dont mind paying proper price, i just keep buying random / wrong rubbish |
| flyback | no I mean they are cheap but good |
| Jazzdude | mr_boo: do you have a resource that lists the arduino due i/o ports? |
| flyback | like $6/pen |
| Celerity | flyback: I bought a ~$40 pen. |
| flyback | you might want a small bottle of liquid or paste also for hot touch up of a tricky joint etc |
| flyback | you can't use the pens cause it will melt |
| mr_boo | Jazzdude: http://www.robgray.com/temp/Due-pinout-WEB.png |
| drac_boy | celerity btw just asking..manual and/or automatic transmission preference? |
| flyback | but pre soldering aPPLYING the pens own your 'canuck' |
| flyback | 0001ACTION trips drac_boy over0001 |
| flyback | I recommend a 186 rosin and then a noclean or something other one |
| drac_boy | 0001ACTION kicks flyback in the rear :P0001 |
| flyback | Celerity, india is a neat country |
| Jazzdude | mr_boo: thanks. How do you access the ports in code? |
| Celerity | drac_boy: I prefer an automatic |
| drac_boy | celerity ic heh ok |
| davesleep | im gonna try and solder this joint without any flux |
| davesleep | but it may end up messy as fk |
| mr_boo | Jazzdude: by a PIO controller software |
| mr_boo | Jazzdude: then i can switch individual pins |
| flyback | Celerity, http://www.scribd.com/doc/30994307/Diag-Commands-Alpine |
| drac_boy | manual alone here (what with cheaper maintenance, one less fluid to worry about, and being able to hold engine rpm on any inclines) but mm yeah |
| Celerity | drac_boy: not for the lack of knowing how to drive a stick but the traffic here is so bad that it doesn't make sense. If I were given awesome roads with virtually no traffic, I'd love a SMG. |
| flyback | probably not the most up to date Celerity |
| beaky | hello |
| beaky | how do i polish aluminum |
| flyback | Celerity, http://www.msfn.org/board/topic/158484-solution-seagate-barracuda-72007-pataide-diagnostic-serialuart-port/ |
| beaky | make it sparkling chrome |
| Celerity | drac_boy: Well, the maintenance sure, but practicality auto kinda wins. |
| Celerity | flyback: :O |
| Jazzdude | mr_boo: do you have an example? I have a due too but never came around to look at the actual port programming |
| flyback | samsung have something similiarf |
| drac_boy | celerity is your town a bit like dublhi-something (sorry I can't spell) with everything looking like total chao but in a organized way strangely especially with noone following lane lines? |
| flyback | not nearly as nice though |
| Celerity | drac_boy: I'm in Mumbai |
| mr_boo | Jazzdude: http://forum.arduino.cc/index.php/topic,175617.0.html |
| flyback | beaky, yeah good question to ask and btw #1 don't use chrome chemicals on al |
| Jazzdude | mr_boo: thanks! |
| flyback | use polishing compounds for al |
| drac_boy | celerity..what was the name of that major city again anyway? I'm surprised I forgot how to spell it now |
| evilbetty | bleh |
| beaky | flyback: are they food safe |
| Celerity | I've been told that traffic discipline here is the best as compared to other places but honestly it aint so great. No lanes, constant honking, indicator is completely optional, what else! |
| evilbetty | dumb ppl are convinced i am wrong and i am concinved they are |
| Celerity | drac_boy: Do you mean New Delhi? |
| flyback | beaky, I am sure you can find food safe polishing compounds |
| Celerity | flyback: I shall look into it. My USB to UART is kind of like 3 timezones away |
| flyback | 0001ACTION bites Celerity 0001 |

| drac_boy | celerity ah yeah. delphi ofc . wasn't that the same city a very rich man had a very tall tower with tampered-cone-shape top built a few years ago in the lust for 'tallest building'? |
| Celerity | what? |
| flyback | hang on I will show you |
| flyback | https://www.youtube.com/watch?v=6BkVc8mVUmI |
| Celerity | drac_boy: I believe you're talking about mumbai or are you talking about Dubai, where beaky lives? |
| Celerity | flyback: well lamington is kinda neat |
| flyback | Celerity, also I guess mushroom farming is popular there |
| flyback | that's cool |
| Celerity | I need to go there since I need a new hard drive |
| Celerity | is that you? |
| flyback | hell no |
| Celerity | lol |
| flyback | 0001ACTION is austistic he's never lived in a house more than 20 mins from the last one0001 |
| flyback | i'mm still living with grandma at 40 |
| drac_boy | mm know what..let me see if theres even a list of very tall buildings..one sec.. |
| Celerity | drac_boy: Burj Khalifa |
| Encrypt | Hello there o/ |
| flyback | pa here, usa |
| beaky | i love electronics |
| Celerity | oh |
| Celerity | we all love you too beaky |
| flyback | we are the mushroom capital of my country though |
| flyback | mmmm |
| Celerity | flyback: you have amazon, trust me it's way better than manish market |
| flyback | been a while since I had some some good portabella |
| Celerity | I've actually never bought a mushroom since I came here |
| drac_boy | celerity..ah right..yeah it was Burj I must had been thinking of . almost 830m tall 0_0 |
| davesleep | what am i actually looking for |
| Celerity | That's the tallest building |
| davesleep | with the flux |
| drac_boy | arab..mm |
| flyback | Celerity, and yes I am talking about the food mushrooms |
| flyback | drug mushrooms are stupid |
| Celerity | ping beaky about that drac_boy |
| xDR1TeK | howdy |
| flyback | beaky, cool, feel free to idle here any time :) |
| drac_boy | oh and even arab has the tallest HOTEL too o_o |
| Celerity | flyback: I tried an awesome mushroom in Dubai last year. It was flowery, and in a gravy tasted AWESOME |
| drac_boy | 355m tall . I can't imagine the view from the upper rooms |
| Celerity | I don't know the name though |
| xDR1TeK | arab suck balls |
| flyback | davesleep, there's a few other good flux brands besides kester |
| Celerity | drac_boy: I've been to dubai, and it's pretty tall |
| drac_boy | celerity yeah if I remember and I see beaky I'll ask him about his own opinions :) |
| davesleep | gah there are loads of flux pens |
| Encrypt | On OshPark website, I can see: 'They’re 1.6mm thick (0.063 inches) with 1 ounce copper on both sides.' about the PCB they manufacture |
| flyback | Celerity, mushroom growing can also be very cheap |
| Encrypt | What is the copper thickness then? |
| davesleep | http://www.amazon.co.uk/Kester-186-Rosin-Plate-Welding-Repair/dp/B00KCR7RTS |
| flyback | you can bucket grow some of them |
| davesleep | is that what im looking for? |
| flyback | yep |
| flyback | but I would also get one non 186 |
| Celerity | flyback: no idea. didn't try. |
| Encrypt | Is it 1 ounce per square inch? |
| flyback | for stuff that is too hard to clean rosin off |
| medfly | sweet. I have DC voltage. I feel like a winner |
| drac_boy | celerity anyway I'll stick to 1-5 floor high things myself but to our own ;) |
| mr_boo | is it possible to let a pwm clock trigger a software interrupt when overflowing? |
| flyback | Celerity, well I mean for some poor areas of india it's very cheap to do and still make a few $$ |
| Celerity | flyback: now that you told me about manish market, I think I should make a trip there instead of relying on ebay. |
| flyback | well ebay is good also |
| flyback | I like how they sell all the motors salvaged from dead printers etc at the market |
| Celerity | I can't buy stuff on ebay.com with an Indian debit card because of RBI's ruling for Paypal |
| flyback | som eof those older ones are bulletproof |
| flyback | nice steppers |
| Celerity | oh yeah, no one gives out shit here for free. |
| flyback | even sometimes 20 yr old steppers from a large dead copy machine |
| flyback | you just pop in 2 new bearings |
| flyback | good to go |
| dongs | looking for a ~30-40pin board to board connector that should work with ~200mhz clock and cheap. pin pitch not less than .5mm preferred, no dip |
| drac_boy | celerity..I don't ever want to touch either paypal or ebay due to their questionable anti-customer face sometimes..but to our own personal choices |
| flyback | the bearings just get tired from wear and eating toner |
| drac_boy | :-> |
| davesleep | oh, i want one that i DONT have to clean |
| Celerity | drac_boy: but what other option do I have if you want to buy electronics online |
| drac_boy | celerity many |
| flyback | davesleep, they make plenty of noclean ones |
| davesleep | mate. 30 quid |
| flyback | but yo ushould still have 1 186 |
| Celerity | drac_boy: even most chinese retailers use paypal instead of wallet |
| davesleep | its just for repairing my headphones for now |
| flyback | btw if you mix 50/50 acetone/isopropyl it melts rosin right off |
| flyback | do not spill on plastics |
| davesleep | there's little space to clean and it's surrounded by plastic XD |
| flyback | 951 is a noclean I dunno if I like that one it evaporates too fast for me to unsolder shit |
| flyback | 2231 is one of their newest |
| flyback | Celerity, you can get cp2102's for like $5 us but $2 china |
| flyback | fine for a lot of stuff |
| flyback | like hd talking |
| Celerity | what's a cp2102? |
| flyback | nothing beats ftdi but they aren't bad at all |
| flyback | better than pl2303 shit |
| flyback | ttl uart |
| Celerity | oh those |
| Celerity | nice |
| flyback | i'd get the cp2104 |
| Celerity | ok |
| flyback | has 4 gpio also |
| flyback | I am rebuilding 4-5 old laptopds |
| Celerity | flyback: the prices have increased since that video |
| flyback | p2/p3 boosted ram to 512mb and put in a usb 2.0 card |
| flyback | just to use as dedicated serial terminals for things like talking to hd's etc |

| mr_boo | scrts: datasheet didn't mention it |
| x-fak | hello |
| scrts_w | mr_boo: what device? |
| dhrosa_ | mr_boo: not reliably: http://www.allaboutcircuits.com/vol_4/chpt_3/10.html |
| dhrosa_ | mr_boo: depends on the device, your datasheetwill have an input threshold voltage |
| mr_boo | scrts_w: CD4020 binary counter |
| R0b0t1 | mr_boo: CMOS is a gate construction technology that can be designed to run at a variety of voltages |
| R0b0t1 | your part is designed to run at a subset of all the possible CMOS voltages |
| scrts_w | mr_boo: the inputs must not exceed VDD+0.5V |

| medfly | so, am I being stupid |
| darsie | Do you think a 'dead', bulged Li-ion battery is a fire/explosion risk? The cover is bulged with gas, but the actual battery inside doesn't feel deformed. |
| medfly | I have this thing that is a ramp between 0-10V, and I connected a zener diode across it, then tried to measure it |
| dhrosa | probabluy |
| medfly | shouldn't the zener diode short it whenever the voltage is above its cutoff (5.6V in this case) and then I'll get a 0-5.6V ramp? |
| Hyratel1 | darsie, yes, its' a fire rist |
| Hyratel1 | risk |
| darsie | thx |
| Hyratel1 | put it in a firebag and take it to a battery recycling center |
| x-fak | dhrosa , i bought this one: http://uk.rs-online.com/web/p/tweezers/0549628/?searchTerm=549-628& |

| Hyratel1 | yeah, tip |
| Hyratel1 | don't |
| darsie | :) |
| darsie | thx |
| dhrosa | the lithium in a primary cell is actually pretty recoverable apparently |
| medfly | help :( |
| dhrosa | not from rechargable ones iirc |
| darsie | It's a rechargable. |
| dhrosa | medfly: yes that's should should happen |
| dhrosa | medfly: instead whathappens? |
| Hyratel1 | darsie, don't |
| darsie | Hyratel1: Cause of the Li or of other ingredients? |
| Hyratel1 | they're a very unstable fire-explosion risk |
| Hyratel1 | which is why hobby aviation requires firebags when charging them in the field |

| flyback | you DEFINTELY want non magnetic tweezers |
| medfly | guys |
| darsie | Is it bad to charge Li-ion batteries with rectified 50 Hz AC pulsing DC at 0.5 C average current? |
| waressearcher2 | what is the difference if I connect few light bulb in serial or in parallel ? |
| medfly | what happens if I have a diode across a 0-10V ramp |
| flyback | UH DARSIE |
| x-fak | flyback , i bought those one: http://uk.rs-online.com/web/p/tweezers/0549628/?searchTerm=549-628& |
| medfly | I feel like I should get a 0-5V ramp |
| flyback | IT'S BAD TGO CHARGE LIION WITH REGULATED POWER EVEN |
| medfly | why is this not happening :( |
| x-fak | but i got them for 7€ here |
| flyback | use a dedicated charger or at least build one with a charger ic |
| flyback | DO |
| flyback | NOT |
| flyback | *CANUCK* |
| flyback | WITH |
| flyback | LITHIUM BATTERIES |
| darsie | flyback: What's wrong with regulated power? |
| evilbetty | why not? |
| flyback | except lithium phosphate |
| evilbetty | if they dont take advice let their house burn down, they'll learn |
| R0b0t1 | raffahacks: Read the docs/google for it. Usually there's a kernel module involved (if your board runs a full OS). |
| flyback | darsie, cause there's so many ways to blow it up |
| medfly | :( |
| dhrosa | darsie: because you don't just charge a li-ion with regulated power |
| x-fak | flyback , i also ordered a AOYUE Int936 soldering station, do you know this one? |
| flyback | no but x-fak it's better than unregulated shit that I used all my life and didn't know better till about 7 yrs ago |
| darsie | flyback: As long as you don't exceed 4.2 V or 0.7 C. |
| flyback | the iron on my 968 was too weak 35w so I bought a 50w one |
| darsie | flyback: I'm monitoring I and V. |
| flyback | 968A has a 70w now |
| evilbetty | once you bought crappy chinese soldering stations its too late asking people's opinion about it isnt it? :p |
| flyback | darsie, still I highly recommend you do this with a mcu or chasrger ic |
| x-fak | flyback , it is one of those hakko 936 clone out there |
| flyback | don't fuck around |
| flyback | x-fak, yeah like I have |
| flyback | not the greatest but not bad |
| darsie | flyback: I don't have one. Hmm, actually I do .. for 18650 batteries. But here I have come bare cells from a died notebook battery. |
| darsie | s/come/some |
| flyback | you can't just limit current and voltage and charge them forever |
| flyback | they detonate when they hit 100% |
| raffahacks | I think i made a mistake buying it instead of raspberry pi. Many more function, but 1/100000 community |
| x-fak | flyback i got it for 45€, a hakko one would be more around 100€ i think |
| flyback | they won't just bleed off heat like nicd, lead, etc |
| flyback | x-fak, trust me, it's still amazing compared to unregulated pencil irons |
| darsie | flyback: Current is within limits and I'll take action at 4.2 V. |
| flyback | you will like it |
| flyback | darsie, JUST BE careful |
| R0b0t1 | I mean they catch on fire but it's not like napalm shoots out of them |
| flyback | remember if you try to put out a lithium fire with co2 or water it bends them over and canucks oxygen in the eh-hole |
| flyback | R0b0t1, actually yes it can |
| darsie | flyback: Sure, I don't want to damage them. I just want to know if pulsing DC is bad. |
| flyback | i'm not worying about damaging them |
| flyback | I worrying about you being dead or your kids |
| flyback | another thing to do |
| flyback | go to home depot etc |
| flyback | get a cheap ceramic or stone flower pot |
| darsie | My life sucks anyways and I don't have kids. |
| x-fak | flyback , i bought it because i had a set of 12 hakko tips which i could mount because of the special tip system hakko uses, so i will mount my hakko tips on this AOYUE station |
| evilbetty | like i said, let them burn their house down , they'll believr you after |
| flyback | x-fak, yeah I can use hakko tips also |
| flyback | in fact I might try some |
| Hyratel1 | darsie, yeah, you should only ever use a microchip charger for LiIon |
| flyback | I wonder if the tips I get are junk |
| darsie | I'm stressing my 1.5 A power supply to 1.9 A. |
| flyback | anyways gtg |
| darsie | flyback: thx. cu |
| Hyratel1 | darsie, Lithium Ion batteries are Not To Be Fucked With |
| x-fak | i watched the very good review of EEVblog about the Yihua 936, i wish i could find one for 16$ lol, i think its close to the AOYUE one |
| Hyratel1 | also LiPoly |
| `Nerobro | Aw, come on. They're fun to make burn |
| darsie | Hyratel1: uC chargers don't do it any better then what I do manually. |
| flyback | WRONG |
| flyback | EVERYONE COVER THERE EYES |
| darsie | flyback: you gtg ;p |
| flyback | darsie, STUPID CANUCK |
| flyback | darsie, STUPID CANUCK- |
| Hyratel1 | darsie, sorry, I call bullshit |
| flyback | darsie, STUPID CANUCK- |
| raffahacks | darsie: on ebay 5pcs 5v micro usb li ion charger modules for 2$, don't risk |
| darsie | lol |
| Hyratel1 | flyback, ENOUGH |
| `Nerobro | they work. they're just really slow |
| flyback | darsie, YOU DON'T FUCKING GET IT |
| flyback | 100% IS BOOM |
| darsie | no |
| darsie | Tell me. |
| flyback | there's no opps this is warm etc |
| darsie | What's wrong with 1.88 A and 3.95 V? |
| raffahacks | flyback: please.. |
| flyback | cause if you miss stopping it at 100% |
| flyback | they detonaTE |
| darsie | Ok, I won't miss it. |
| darsie | And they will explode at best, not detonate. |
| p0g0 | isn't detonate and explode sort of the same thing? |
| darsie | just sort of. Detonation happen at supersonic speed, IIRC. |
| Celerity | so do we want a detonation? |
| darsie | No. Not atm. |
| Celerity | 0001ACTION hands out the supercharger plug0001 |
| Celerity | 0001ACTION puts the plug away0001 |
| raffahacks | WOW! I will build a cheap liion bomb! |
| darsie | I'll switch to my 18650 Li ion charger at 4.2 V for the final charge. |
| Hyratel1 | we warned you |
| darsie | Yes. But you didn't tell me whether rectified AC ripple DC is bad. |
| evilbetty | i need director responsibilities |
| evilbetty | i need to fire 80% of my colleagues |
| Hyratel1 | darsie, yes we did |
| flyback | http://www.youtube.com/watch?v=bZ8IsMRFM5o |
| flyback | I might do this |
| Hyratel1 | and the answer is 'very bad' |
| raffahacks | My friend connected a laptop batt to the ac plug.. |
| darsie | Hyratel1: Ok. But I don't trust that answer. I think you just said that cause you think manual charging is bad, generally. |
| evilbetty | if i had such friends i wouldn't announce it in public |
| flyback | darsie, and that's just a coin cell |
| flyback | you idiot |
| R0b0t1 | p0g0: Detonate involves the material breaking down due to a shockwave, explode can be contained conflagration. |
| p0g0 | 0001ACTION pedantlically notes that the first 3 english web dictionaries I looked at define 'detonate' as an explosion0001 |
| raffahacks | My idiot friend |
| Hyratel1 | darsie, *facepalming across the sky* |
| evilbetty | say neighbour |
| raffahacks | My neighbour.. |
| SpeedEvil | Detonate - in the scope of explosives - means 'a propagating exothermic reaction occurring at more than the speed of sound in the material. |
| Hyratel1 | p0g0, that's common, not scientific |
| evilbetty | i kicked out dumb friends, and also those smarter than me |
| R0b0t1 | p0g0: SO WRONG |
| p0g0 | SpeedEvil: thx |
| evilbetty | i have 1 left |
| Hyratel1 | a gas detonation is a turbulent deflagration |
| waressearcher2 | anyone seen evilbetsy ? |
| evilbetty | deflatulence |
| darsie | flyback: That cell has a steel case which may build up more pressure. I just have a plastic bag around it. |
| SpeedEvil | Hyratel1: gas explosions canbe supersonic |
| flyback | darsie, http://www.youtube.com/watch?v=k9mcNvOGKtI |
| flyback | this is your FAIL ON LITHIUM |
| waressearcher2 | haven't seen her in a while, after I add her to ignor list |
| flyback | any questions? |
| Hyratel1 | SpeedEvil, yes, usually enabled by a turbulent flame front |
| p0g0 | RoBo_V: beat me, I am only reporting a verifiable fact- search up 'detonate vs explode english definition' |
| p0g0 | oops |
| p0g0 | ^ R0b0t1 |
| SpeedEvil | Hyratel1: No - due to IR emissions triggering the next bit |
| medfly | how sensitive is TTL stuff |
| medfly | can I put in around 10V? |
| SpeedEvil | no |
| SpeedEvil | 0-5V in |
| medfly | ok |
| raffahacks | His battery didn't explode! Luckily for his life it was a Sony Vaio.. |
| Celerity_ | darsie: The thing is, this is one of those, 'If you have to ask, you probably shouldn't be doing it' kind of situations. |
| raffahacks | But not for his purse! |
| medfly | SpeedEvil: I tried to put a diode across between the + and gnd and I got mostly nothing :(( |
| darsie | flyback: That plane battery burst in flames, no explosion. |
| dhrosa | medfly: which direction did you put it |
| Celerity_ | Li-Ion + improper energy delivery mechanism = No battery + No operator |
| medfly | it's a zener diode. does it matter? |
| dhrosa | medfly: a zener has a 0.6V drop in one direction, and V_z (I think5.6V for your application) |
| dhrosa | medfly: yes aboslutely |
| raffahacks | Sorry for my stupid question, but has ac plugs got polarity? |
| dhrosa | medfly: they behave differently in each direction |
| flyback | http://www.youtube.com/watch?v=UnDoyft8E8U |
| flyback | OWNS YOUR 'CANUCK' |
| flyback | nicely done |
| dhrosa | medfly: if you wire it like a normal diode, it has a 0.6V drop like a normal diode |
| flyback | sound effects module etc |
| raffahacks | They cannot! |
| flyback | that's sweet |
| dhrosa | medfly: if you wire it in reverse, it has a5.6V drop |
| medfly | ok |
| medfly | so I put it in reverse? |
| medfly | okay.. |
| dhrosa | yes |
| medfly | let's see |
| raffahacks | But they have some kind of polarity, haven't they? |
| dhrosa | raffahacks: whay do? |
| waressearcher2 | what about my bulbs ? |

| beaky | ah never thought of batteries |
| beaky | is there a way to get my stm32f334 to bootstrap itself off batteries |
| p0g0 | switch the power on |
| beaky | or should i just use a linear regulator |
| beaky | (like the onboard one that gives 3v3) |
| evilbetty | a resistor divider |
| p0g0 | 0001ACTION heads off to move a small horde of steel, g'day all0001 |

| beaky | evilbetty: thats bad since it wont regulate and also has high output impedance |
| beaky | oh |
| flyback | http://www.youtube.com/watch?v=XxZsuOLOzr8 |
| beaky | what about thermal and OC protection |
| evilbetty | get thing enough wire |
| evilbetty | thin |
| evilbetty | no seriously |
| evilbetty | i would use 2 batteries |
| darsie | manual Li ion battery charging: http://www.bksys.at/bernhard/temp/P1130318.JPG |
| evilbetty | keep 1 batttery at 3.3v with some monitoring, and use the 2nd one to charge the first one if it drops below 3.3v |
| evilbetty | and a resistor to discharge it if iy goes above 3.3c |
| beaky | lol |

| kdosa | what kind of tool (PSU) do I need to adjust the phase shift between AC vold and current? |
| dhrosa | kdosa: |
| evilbetty | a crapacitor? |
| dhrosa | oops |
| dhrosa | kdosa: what exactly are you trying to do |
| kdosa | I need it to calibrate for an electricity meter, it requires a known voltage, current and phase shift |
| dhrosa | kdosa: capacitors and inductors provide phase shift |
| kdosa | dhrosa, does it matter what is the value of capacitance as long as it conforms the voltage rating? |
| dhrosa | kdosa: the phase shift depends on the capacitance and the frequency of the signal |
| kdosa | dhrosa, thank you. |
| t4nk810 | can anybody explain this to me i am new in electronics http://www.nxp.com/documents/application_note/AN97032.pdf |
| dhrosa | t4nk810: explain what exactly |
| t4nk810 | ok |
| archivist | you want an entire app note explaining! |
| SpeedEvil | It's a monitor |
| SpeedEvil | It explains how it works |
| SpeedEvil | A CRT monitor |
| archivist | ask a better question |
| SpeedEvil | That |
| t4nk810 | i know it monitor i dont understand parts of it |
| Rab | Side note, this is a pretty good circuit description. |
| archivist | how should we guess what you want to know |
| SpeedEvil | t4nk810: why are you trying to understand it? |
| t4nk810 | ok |
| jeremyabel | monring |
| jeremyabel | morning even |
| t4nk810 | first of all where is data input |
| SpeedEvil | t4nk810: what data input do you mean? |
| t4nk810 | thr video signal |
| SpeedEvil | t4nk810: this is not a digital monitor - it's analog |
| evilbetty | haha |
| t4nk810 | ok why using eeprom |
| evilbetty | colleague calls from station 'all trains are cancelled' |
| evilbetty | and panic broke out among the ppl still in the office |
| evilbetty | those by train anyway |
| mr_boo | theBear: around? |
| SpeedEvil | t4nk810: because it's got microcontrollers in it |
| SpeedEvil | t4nk810: and to hold config data |
| Rab | t4nk810, I don't believe the video input is actually included in the description. Everything I see is oriented toward low-level monitor control. |
| SpeedEvil | It is - it's a compelte monitor design - with BNC RGB and sync inputs |
| SpeedEvil | (can also do composite) |
| evilbetty | 22 inch Sun CRT ? |
| evilbetty | if you put 2 of those on your rear seats in winter you have double the traction of your rear wheels |
| Polesch | I got myself my first variac, supposedly with isolated outputs |
| Rab | SpeedEvil, the video controller is a TDA4885. But the schematics don't appear to include that section. (It is shown in the block diagram, though.) |
| hjf | heh i wanted to make a SMPS for my audio amplifier |
| hjf | seems like i'm gonna have to just use a transformer |
| hjf | http://www.ti.com/lit/ug/slou293c/slou293c.pdf |
| hjf | look at that motherfucker |
| evilbetty | do we have to |
| jeremyabel | guys my game dev partner just told me we're all wrong about ohms law |
| jeremyabel | it's really 'vidjagames = illustions*raditude' |
| evilbetty | wrong type of humour for this channel i guess |
| jeremyabel | whateverrrrrr |
| hjf | that is some complicated PSU. dang |
| evilbetty | exacrlt what i thought when i saw your joke |
| hjf | $150 for the EVM shit |
| jeremyabel | evilbetty: wasn't even my joke! I just liked it is all |
| jeremyabel | I FIGURED IT'D BE FUN TO SHARE OK?! |
| hjf | jeremyabel: calm yo tits |
| evilbetty | or shake em good |

| theBear | wrong type of humour for people that don't own dice with more than 17 sides |
| evilbetty | that includes me |
| evilbetty | i own no dice |
| evilbetty | i wouldnt know why |
| theBear | why you don't own them ? cos you ain't a d+d nerd, dude ! |
| evilbetty | i know |
| evilbetty | i wouldnt know why to own dice that is |
| mr_boo | theBear: hi |
| theBear | oh, there is that (the real and original) diceman concept, that's a reason to have one or two |
| theBear | but 2-6 sides is more than enough |
| theBear | ho |
| hjf | theBear: http://i.imgur.com/PaPjD4r.jpg |
| mr_boo | theBear: i spoke to a guy on this forum and he concluded that the DAC i'm using need to have the master clock and sample clock in sync |
| theBear | i even found it in the datasheet late lastnight |
| theBear | page 9 maybe, under clock sources or sync or something |
| Polesch | Can you make a full-wave rectifier that works on o-250 VAC universally? Four big diodes and a couple of 400V caps? |
| theBear | hjf, heh, but i can pretend you're cool and those are for professsional reasons |
| mr_boo | theBear: so now i've used a digital counter to derive the sample clock from the master and even the bit clock |
| hjf | theBear: these are for sale |
| theBear | mmm, tradition DOES often know best |
| theBear | hjf, <nudge nudge wink wink> oh i know buddy, i know |
| mr_boo | theBear: if i tie the data pin high or low doesn't affect output at all |
| mr_boo | theBear: do you think i can finally pronounce the part dead |
| hjf | theBear: hey, $1 each! |
| theBear | what data pin, and under what conditions, and i'd like at least a suspected cause of death before i give you that permission |
| theBear | hjf, but, i want ones with chamfered edges and at most 6 sides, i should get a discount ! |
| theBear | ooh, or howbout pensioners discount ? |
| theBear | have you got a 4 sided one ? or a 3 sided one ? |
| hjf | theBear: 4, 6, 8, 10, 12, 16, 20 |
| theBear | i want a 3 sided one ! |
| hjf | 100 too but i dont stock em |
| theBear | have you got one loaded for 17 black that can replace a roulette wheel ? |
| Scott0_ | hjf: I didn't break it :P |
| hjf | theBear: thats not D+D nerddom |
| mr_boo | can someone recommend a digital audio interface board with say 4 channels of 24-bit audio output |
| hjf | Scott0_: what was it |
| theBear | and i ain't no d+d nerd ! and double negative makes it doubley true ! |
| Scott0_ | its supposed to show 0mA for when there's an alarm |
| hjf | Scott0_: told ya |
| Scott0_ | hjf: there's also a secret programming document they don't send customers |
| evilbetty | lol |
| mr_boo | an audio shield is available for the arduino due but it only has two channels (stereo) |
| theBear | oh, basic alarm system eh ? |
| Scott0_ | which I used to put it into a simulation mode |
| evilbetty | ram attacks quadcopter and its owner :p |
| Scott0_ | theBear: no, a $4000 electromagnetic flow meter |
| hjf | mr_boo: you could make your own with any PC audio CODEC (ALC 88x) |
| theBear | hmm, sounds like a basic alarm system |
| theBear | htf does that work ? water isn't magnified |
| hjf | TIL magnified |
| theBear | actually yeah, that's why i got a handful of salvaged pc codecs (and one from a warrantied pcb in a shitty modern marshall amplifier) in the other room |
| mr_boo | hjf: i don't wanna make the board myself if i don't have to |
| theBear | all you need is a blowtorch and a soundcard or a mobo or a dead laptop |
| theBear | oh, and the most important ingredient.. maaaaaaad skills, yo ! |
| hjf | mr_boo: i mean i made my own, it was really easy and single sided. you put the codec + a xtal, then break out all the otehr pins |
| hjf | mr_boo: do you etch boards at home? i can send you the Eagle files for the one i made. dunno if all these have the same pinout. maybe they do |
| hjf | mr_boo: and the chip and xtal you can get from any old motherboard for free |
| theBear | ok, i gonna go watch some more skinny fresh prince and blind woody from cheers movie |
| mr_boo | hjf and theBear this is my CS4382 that i blowtorched from a board http://www.carmi.se/misterstarshine/img/conv_1.jpg |
| theBear | cataracts at a glance |
| theBear | ahh, the board from the other night pre bypass.. nobbad |
| hjf | mr_boo: cute but doesn't that need a xtal? |
| mr_boo | hjf: i needs a master clock but i think i've killed it while blowtorching it off the Audigy card |
| theBear | and practice your soldering, we talking more consistant amounts left on the joint, and not letting the flux run out (stop smoking) before you take the iron away |
| hjf | mr_boo: you used like, actual fire? |
| theBear | anyway, tv, plus i gotta recline more, my doctor stabwound stopped getting better everyday, and i think i can do better than that |
| mr_boo | hjf: i shielded away the chip and heated until the part precisely loosened |
| blkcat | the pin at the very top left is about what you want |
| blkcat | a lot of those joints have waaay too much solder |
| mr_boo | however the color of the pins got somewhat yellowish dark in places |
| hjf | mr_boo: you probably killed it. you should get a heat gun |
| theBear | hjf, i've used both post-mapp style plumbers torches, and most recently for some 3.5mm jacks and a couple chips i used a bbq sized gas bottle + tube -> traditional jewellers torch |
| mistry | hello, i am looking for a gpio expander for a microcontroller based project. which is the most easy-to-find chip? |
| hjf | theBear: i used that for soldering fat wire |
| theBear | blkcat, except the ones with holes in them, tho they owuld be ok if the flux was still there |
| SpeedEvil | mistry: another microcontroller |
| theBear | yeah, io expanders are so 80s |
| SpeedEvil | mistry: practically - the right solution is generally to pick a microcontroller of a similar series with more pins |
| anton02 | how come capacitors dont have current ratings, only voltage |
| hjf | theBear: star grounds for my audio amplifier. 1mm wire on a 5x5cm board = LOTs of dissipation so impossible to do with my wimpy iron |
| SpeedEvil | anton02: they do have current ratings. |
| SpeedEvil | anton02: in the datasheet generally - or expressed as wattages or .. |
| mr_boo | hjf: what are your specifications of your shield? |
| hesperaux_ | hjf, 5x5cm? iteadstudio? |
| hesperaux_ | good morning all |
| hjf | hesperaux_: no, like, a 5x5cm bare board |
| anton02 | SpeedEvil: oh okay, thanks |
| mistry | SpeedEvil : if i have a very large requirement then? |
| hesperaux_ | ah nvm |
| hjf | mr_boo: nothing really. just the AC97 codec, a crystal, and breakout everything to the outside. audio inputs/outputs capacitor coupled. 6 channels |
| hesperaux_ | mistry, how many I/O do you need? |
| hjf | mistry: for output only you can use shift registers |
| mr_boo | hjf: i can get those from old motherboards right? |
| hjf | well, for input only too, but 74HC595 is really easy to find |
| mistry | hjf : good idea |
| hjf | mr_boo: yes |
| SpeedEvil | mistry: 'very large' ? |
| mr_boo | hjf: could i have your eagle files? |
| hjf | mr_boo: wait |
| mr_boo | hjf: multilayer board? |
| ShadowJK | fluke is sellong ir camera for 500 eur, except it's not a 'camera', and displayed temp is average of entire viewfinder. sure looked like 32x32 or better with visible ligjt overlay though |
| hjf | mr_boo: no |
| Polesch | ShadowJK, Flir One for the iPhone |
| ShadowJK | iphone is aroind 700 eur |
| mr_boo | hjf: double sided? |
| SpeedEvil | ShadowJK: the flir one is SPI imager |
| Polesch | ShadowJK, can use it on many phones or even standalone |
| hjf | mr_boo: nope. single sided |
| SpeedEvil | with source code available |
| hjf | mr_boo: hjf.com.ar/codec.rar |
| SpeedEvil | Polesch: no, you can't |
| SpeedEvil | Polesch: only iphone |
| SpeedEvil | Polesch: and it doesn't work standalone |
| ShadowJK | Fluke VT02 |
| SpeedEvil | (with stock firmware) |
| hjf | mr_boo: dont worry about the capacitors, they are just the .1uF decoupling caps and some 10uF local power caps |
| hjf | mr_boo: and the 'top' layer (red traces) are wire jumpers |
| ShadowJK | yeah but because fluke and only 500 i might be able to get $work to pay :D |
| Polesch | mikeselectricstuff has a video on Flir One |
| hjf | mr_boo: remember this talks AC97, not I2S |
| mr_boo | hjf: yeah i use the same approach |
| mr_boo | hjf: haven't used any codec before |
| mr_boo | hjf: hope it is easy and efficient to program on the Arduino Due |
| hjf | mr_boo: i used it with an FPGA |
| hjf | that pin header was supposed to be compatible with xilinx's spartan-3 starter kit |
| mr_boo | hjf: thanks for the eagle files |
| ikarus | 'Professional Low Noise Microphone Cable' I am pretty sure out of all those lies I may be able to trust one |

| ShadowJK | it's kinda fun going to trade fair when the salespeople that usually say 'fuck off' on the phone suddeböy talk with you |
| ShadowJK | .suddenly |
| evilbetty | sissyboy |
| hjf | mr_boo: but do yourself a favor and go to the hardware store and get a heat gun |
| hesperaux_ | i don't know what to do guys |
| hesperaux_ | -_-' |
| mr_boo | hjf: i have a heat gun. i was just stupid that i used the mini torch |
| hesperaux_ | i have a little time, but can't shake the desire to sit here and stare |
| hesperaux_ | how do I productivity? |
| ShadowJK | get a boss |

| hesperaux_ | lol |
| hesperaux_ | i have one, but i'm not leaving for work for another hour or two |
| loonquawl | get depressed and interested in philosophy |
| hesperaux_ | xD |
| mistry | SpeedEvil , hjf : thanks |
| hjf | hesperaux_: productivity you say? http://i.imgur.com/WwTcNBT.jpg |
| hesperaux_ | that could work, but i as hoping to code something up |
| hesperaux_ | hjf, that's a lap dog |
| hesperaux_ | why do huge labs always do that lol |
| hjf | hesperaux_: luckily this one is a small one |
| hesperaux_ | indeed, but much larger than a normal small dog |
| evilbetty | lol |
| hjf | you'd have to be lucky to find a pure lab on the street |
| hesperaux_ | my g/f's dog does that too |
| hjf | this one is nagging me to go for a walk |
| hesperaux_ | they do that |
| hesperaux_ | hence, i prefer cats :P |
| evilbetty | an article that many women demand some personal time without their men, but that they dont give their men some time for their own |
| hjf | hesperaux_: our 2 cats were stolen |
| hesperaux_ | D: |
| hesperaux_ | who steals cats wtf |
| hjf | hesperaux_: i wish i knew |
| evilbetty | some dumbass or a craey cat woman |
| hesperaux_ | fail |
| hesperaux_ | that sucks hjf |
| evilbetty | no sane person would want cats |
| hesperaux_ | lol |
| hesperaux_ | i never understood the intensity of feeling regarding cat people vs. dog people |
| evilbetty | this is internet |
| evilbetty | what else is there to understandµ |
| hesperaux_ | i guess |
| hesperaux_ | why is my nick stupid |
| hesperaux | there |
| hesperaux | geez, today is a day for sleeping |
| ikarus | wonder if DX sells a dirt cheap chinese version of those machine warning lights (pole mounted availible in many colours) |
| mr_boo | hjf: how do i connect it if i want only three 24-bit signals at 32kHz samplerate? |
| evilbetty | i think i got 1 or 2 of those lights |
| evilbetty | in orange |
| ikarus | evilbetty: heh |
| ikarus | I want a traffic light one hooked up the status monitoring system |
| evilbetty | i like the stacked ones |
| evilbetty | yes those |
| mr_boo | hjf: maybe i can read that up in the datasheet for the part |
| mr_boo | hjf: anyway many thanks |
| ketas | i wonder if there are usb cables with 90 degrees angle cable (aligned either way related to plug).. with minimal plug size? |
| ketas | or i need to make my own |
| Rab | ketas, I've seen mini-USB cables of that sort. |
| ketas | such plugs are nice if you want to charge something in backpack or pocket.. without much stress on sockets |
| xDR1TeK | hiiiiii |
| Rab | I see micro and regular USB flavors exist as well. |
| ketas | Rab: i have seen angled plugs.. but they are so big |
| SpeedEvil | ketas: I've been looking on-and-off for this for some years |
| SpeedEvil | ketas: I've seen no purchasable ones |
| Rab | Well, define minimal. You need a certain amount of overmolding to get reasonable strain relief. |
| xDR1TeK | Speedy, nice bling |
| ketas | usb 3g adapter is also where you want it |
| SpeedEvil | http://www.dx.com/p/reverse-qi-wireless-charger-pad-universal-wireless-charger-receiver-for-micro-usb-cellphone-312805 |
| SpeedEvil | Is the closest I've seen |
| ketas | Rab: how much of strain relief the 'strain relief' actually provides? |
| xDR1TeK | moderate |
| ketas | Rab: i've seen some cases where it actually works |
| SpeedEvil | ketas: the primary probem isn't the strain relief - it's the massive lever |
| Rab | ketas, here's an example of r/a micro..is this too large? http://sgcdn.startech.com/005329/media/products/gallery_large/UUSBHAUBXRA.B.jpg |
| ketas | SOME! |
| ketas | damnit, can't view that in moment |
| SpeedEvil | There is no good reason for the plug to be ~20mm long after the port |
| SpeedEvil | ketas: it's a ~20mm long or so right-angle plug |
| SpeedEvil | that is - it sticks out 20mm |
| xDR1TeK | ok |
| xDR1TeK | 20mm |
| xDR1TeK | we got it |
| ketas | cable is much cheape that device |
| ketas | cheaper |
| Rab | Apple provide plugs (magsafe, etc) with very minimal strain relief, and it always seems to be a weak point. |
| ketas | magsafe breaks? |
| ketas | wtf |
| hesperaux | https://www.thetileapp.com/ <--- what kinda transmitter do you think this uses? |
| hesperaux | ketas, hell yes, just not at the 'mag' part |
| Rab | Magsafe apparently breaks all the time, at the cable. |
| hesperaux | ^ |
| hesperaux | i went through 5 chargers under warranty |
| hesperaux | I tried 4 different ways of winding/storing the thing. eventually just loosely coiled it |
| Rab | Which is really sad, because it seemed like such a great improvement. |
| xDR1TeK | hesperaux RFID |
| hesperaux | the rubber insulation crap they use sucks itself out of the strain relief |
| xDR1TeK | but for that NFC |
| ketas | i've seen it come loose easily.. well like designed.. unsure about breaking |
| evilbetty | lol |
| hesperaux | xDR1TeK, it's got a pretty big range though |
| synx508 | I've had a Macbook since 2007 and never had a magsafe fail in any way |
| hesperaux | synx508, mine is a late 2007 model |
| evilbetty | chihuahua died from a baseball player that hit a homerun and the ball fell outside the field on the dogs head |
| xDR1TeK | hesperaux strange, but yes |
| synx508 | maybe I'm doing it wrong |
| hesperaux | i had every piece of hardware replaced under warranty for the laptop except the LCD |
| synx508 | heh |
| synx508 | I've had 1 battery, that is |
| synx508 | it |
| hesperaux | hard drive, DVD drive, battery, 5 chargers, bottom case (because they were nice), and motherboard/vid card |
| hesperaux | so much fail |
| blkcat | my work MBP has a magsafe 2 connector and the cable insulation has cracked and broken just past the strain relief |
| hesperaux | it is not long for this world blkcat |
| synx508 | the apple store volunteered a replacement case on my wife's macbook but she refused because, I think, she liked her stickers |
| hesperaux | lol |
| hesperaux | xD |
| Rab | Other Apple plugs with minimal strain relief experience similar problems, e.g. Lightning. |
| ketas | well, i can be more careful with that small plug but i'm sure moderate strain relief can be put there.. it's not like you need to swing it around constantly |
| hesperaux | when mine got sent to texas for mobo repairs, they were kind enough to just fix everything they saw wrong with it. there was a dent in the case so they replaced it. their warranties are really good |
| hesperaux | had to pay for the Nvidia defect though because during the coverage period for the law suit I took very good care of the thing (never played games). Then it died right after the warranty |
| ketas | i might need to make my own plugs.. |
| synx508 | the mbp is considerably less reliable than the mb |
| xDR1TeK | hesperaux they say: Tile casts a signal across a 100-foot radius |
| xDR1TeK | that is long |
| hesperaux | ketas, you'd be surprised how little that matters. Mine have all gotten jacked up from simple movement of the wire pulling the insulation out of the strain relief |
| hesperaux | xDR1TeK, yeah i know. It's cool but why iphone only, once again.. |
| synx508 | the imac seems to be about the worst Apple product though |
| ketas | take plug.. trim it.. put it in silicone |
| hesperaux | also, no servicable battery or wireless charging |
| synx508 | for breaking a lot |
| xDR1TeK | mmmmmmmmm |
| hesperaux | synx508, i blame their case design |
| xDR1TeK | The app supports up to 8 Tiles |
| hesperaux | plastic is a much better material for laptop cases even if it does look bad/crack |
| synx508 | yes, I think that's it, they simply assumed light use, so when people hammer them they overheat |
| xDR1TeK | so, maybe bluetooth or wifi, but i read somewhere they are tethered |
| ketas | hesperaux: do you pull on cable a lot? |
| xDR1TeK | so it has to be RFID for long range |
| hesperaux | the metal stores heat, even if it does conduct it, making it uncomfortable. the metal also transfers shock into the parts better than plastic |
| ketas | hesperaux: i know apple has so soft cables |
| hesperaux | ketas, I tried various methods of using/storing the magsafe charger to avoid the problem. nothing worked |
| ketas | meh |
| synx508 | apple cables are fairly terrible, i'm not sure why my own magsafe cables seem to survive |
| hesperaux | the connector design is absolutely awesome |
| ketas | do cables usually break for you |
| synx508 | not for me, I'm fairly careful |
| hesperaux | nah, only a couple of micro cables over time |
| synx508 | I don't use the 'magsafeness' |
| ketas | hmm |
| hesperaux | i don't tightly coil my cables or put the connectors under stress if i can help it |
| ketas | strange |
| hesperaux | if i'm going to use my phone and it's charging, i take the cable out ot avoid smashing the strain relief for example |
| ketas | well it's just metal and plastic.. eventually it goes |
| xDR1TeK | man, definitly bluetooth |
| xDR1TeK | When you begin searching for a lost item, your phone tracks the signal strength of your Tile. As you get closer, the app's tracking circle fills in, giving you a clear indication of your progress. |
| ikarus | heh |
| hesperaux | i liked the 180 degree magsafe design, but it probably isn't very good cuz it tends to want to stay attached a lot more than the 90 degree design (old one). I guess the new ones are 90 degree again |
| ikarus | I just want a bunch of antennas in my room for tracking of random items |
| hesperaux | xDR1TeK, and yet 1 year battery life somehow.. >_> |
| xDR1TeK | welllll |
| xDR1TeK | fuk donno |
| xDR1TeK | this is crazy |
| synx508 | knowing where stuff is, that's going to be the next big thing |
| xDR1TeK | who other than apple |
| synx508 | micro-location, I suppose they'll call it |
| hesperaux | things that subsidize our human stupidity are the next big thing |
| hesperaux | i forgot = product. I lost it = product. I don't understand = product |
| hesperaux | I'm bored = product. I'm indecisive = product |
| synx508 | retrospective backups, that'd be a good seller |
| hesperaux | retrospective? what is that? |
| ketas | hesperaux: that's why i want low profile usb with soft cable.. it's amazing how stiff and big some usb cables are.. it moves the DEVICE! |
| hesperaux | what a name |
| synx508 | backups for people who didn't do backups |
| hesperaux | ketas, hehe |
| hesperaux | synx508, how does that work? FS snapshots? |
| synx508 | rebuild from surveillance you didn't know you'd opted into, or something |
| synx508 | still, I think people would pay |
| ketas | ask nsa |
| synx508 | they'd be in a good position to offer it |
| synx508 | if it's all true |
| xDR1TeK | but seriously, what a wonderful website |
| hesperaux | yeah that was a good joke i heard |
| hesperaux | it was a first world problems meme - 'My hard drive crashed and I lost my thesis.. And the NSA wouldn't give me their backup copy' |
| synx508 | seems they don't understand capitalism. |
| hesperaux | lol |
| hesperaux | the government not understanding capitalism? |
| hesperaux | xD |
| synx508 | they're not allowed to, are they? US constitution or something, forbids them |
| synx508 | run as a business, that is |
| hesperaux | yeah, i know |
| synx508 | unlike Britain, where everything is sold off |
| FreezingCold | meh, that was a boring morning |
| hesperaux | yeah i know |
| hesperaux | i woke up later than planned and have to leave for work soon. :( |
| hesperaux | such sadness and regret |
| medfly | so, I tried the entire day to do this stupid thing with a fucking zener diode, and I just found a good connector.. TURNS OUT WE DON'T NEED IT |
| hesperaux | at least snuffeluffegus is here |
| medfly | ~_~ |
| hesperaux | medfly, o/ sounds like fun |
| snuffeluffegus | wot |
| hesperaux | you got paid to do something useless? |
| snuffeluffegus | I'm not here |
| hesperaux | snuffeluffegus, your name is pleasing to the eye |
| snuffeluffegus | I'm there, with you, behind you, all around you. |
| FreezingCold | all I did today was write a stupid math test |
| FreezingCold | kind of annoying |
| snuffeluffegus | I'm in your closet eating your ramen. |
| hesperaux | snuffeluffegus is the matrix |
| Slade-- | hesperaux, dont most people get paid to do something useless |
| hesperaux | fffuuuu not my ramen |
| hesperaux | Slade--, yap |
| medfly | who knew connecting MERELY A DIODE AND JUST LOWERING THE DANG VOLTAGE is so damn hard! |
| medfly | I think that the BNC to crap connector I used was bad |
| hesperaux | because engineering |
| medfly | bnc to just random wire which is made by someone ripping off the bnc end of a cable and soldering bits was probably bad |
| snuffeluffegus | Wire cutters + electrical tape = universal connector? |
| medfly | indeed |
| medfly | unless its high frequency |
| medfly | then you should probably wrap it back in conductive tape |
| A124 | Or small. |
| snuffeluffegus | nah who needs shielding |
| snuffeluffegus | Just dump higher wattage through. |
| A124 | 0001ACTION would get a joke about mom.0001 |
| snuffeluffegus | Irradiated nuts never hurt anyone. |
| A124 | snuffeluffegus: Ever tried to irradiate hazelnuts and eat them? |
| snuffeluffegus | So I do need to restate that. Wire cutters + electrical tape + amplifier = universal connector? |
| snuffeluffegus | <medfly> indeed |
| snuffeluffegus | lol didn't mean to copy you medfly |
| medfly | lol. |
| medfly | well, 'we could juts radiate a little bit' |
| snuffeluffegus | A124, Can't say I have. |
| zigggggy | snuffeluffegus!!!!!! |
| zigggggy | 0001ACTION hugs snuffeluffegus0001 |
| snuffeluffegus | zigggggy, !! |
| zigggggy | :D |
| zigggggy | hesperaux do you rememeber snuffeluffegus from sesame street? |
| snuffeluffegus | I am in lovew with this song http://youtu.be/DD0A2plMSVA |
| hesperaux | no, but i googled him just a minute ago and was happy |
| zigggggy | hesperaux :D |
| hesperaux | i didnt' watch sesame street much as a kid |
| zigggggy | oh :( |
| zigggggy | you missed snuffy |
| hesperaux | i did, mostly |
| hesperaux | i saw it once or twice |
| snuffeluffegus | It's ok I'm still here brotha |
| snuffeluffegus | :P |
| zigggggy | :D |
| hesperaux | lol |
| zigggggy | snuffy is all grown up now hesperaux |
| zigggggy | 0001ACTION hugs snuffy's trunk0001 |
| hesperaux | so he's as big as Clifford? |
| zigggggy | he's as big as an elephant! |
| hesperaux | Clifford was awesome |
| snuffeluffegus | Oh watch out I just railed some coke, so my trunk is like suuupperrr sensitive right now. |
| hesperaux | lol |
| zigggggy | :O!!!!!!!!!!!!! |
| FreezingCold | man this fucking power company wants me to go in person to show my ID |
| zigggggy | omg |
| FreezingCold | it's an hour walk |
| FreezingCold | no, I'm not fucking going :p |
| snuffeluffegus | Feels good man. |
| zigggggy | FreezingCold fax it |
| hesperaux | FreezingCold, send them a Selfie of you with your ID ;P |
| zigggggy | #selfie |
| snuffeluffegus | lol |
| zigggggy | snuffeluffegus do you take selfies? |
| snuffeluffegus | add one of those hi /b/ photos |
| hesperaux | FreezingCold, and you gotta do the anime peace sign pose |
| FreezingCold | zigggggy: I emailed it and they said they got it, but wouldn't accept it |
| zigggggy | lol |
| snuffeluffegus | or do it like infidel style with a newspaper and tied to a chair |
| hesperaux | haha |
| ketas | hugglefungus |
| snuffeluffegus | Eh not regularly |
| snuffeluffegus | I don't have much soul left, so I can't go letting cameras steal the little bit on the daily. |
| FreezingCold | zigggggy: This is part of my reply 'If there is no one capable of operating a printer, I can optionally fax my identification as well.' |
| xDR1TeK | are germans still nazzi? |
| ketas | snuffeluffegus: give you soul to us |
| snuffeluffegus | Not most of them. They're now one of the most tolerant countries in the world. |
| snuffeluffegus | Probably a great place to live. |
| FreezingCold | oh wait, got an even better way to say it |
| snuffeluffegus | http://youtu.be/MkTcyT-5NZw |
| FreezingCold | 'If [name] Power does not have the technological capacities of operating a printer, I can optionally fax my identification as well.' |
| FreezingCold | :> |
| FreezingCold | I'm aware I'm an asshole, but sadly that's the only way anything is going to change. |
| snuffeluffegus | FreezingCold, it |
| ketas | s/fax/fux/ |
| snuffeluffegus | 's necessary sometimes. |
| FreezingCold | ketas: fux? |
| snuffeluffegus | lol fux his id? |
| snuffeluffegus | That may be uncomfortable. |
| FreezingCold | snuffeluffegus: I still can't believe they expect *anyone* to go their stupid office just to let them photocopy ID |
| snuffeluffegus | It's probably a verification issue. |
| ketas | id should be digital |
| ketas | ! |
| ketas | fuckers |
| snuffeluffegus | It's be solved if the world would finally just adopt gpg or x.509 for verifying e-mail authors. |
| FreezingCold | snuffeluffegus: I've opened $2k to $10k credit services online before |
| snuffeluffegus | It'd** |
| FreezingCold | Never visited an office |
| hesperaux | off to work gents |
| hesperaux | see ya |
| medfly | so, here's a weird thing |
| hagbard | fuck x.509 |
| medfly | I've got a signal which is 10-15MHz (sweep) going through a 16m cable |
| medfly | RG58 |
| hagbard | 50ohm, great |
| medfly | it changes amplitude in an inconsistent manner :-( |
| hagbard | you know, if you're asking for advice, anyone would need more details. |
| ketas | how come every country in world probably had passport.. and only few of them contain digital means of remotely identify it's owner |
| ketas | has |
| hagbard | like, how are you measuring the amplitude? whats terminating this cable |
| medfly | ketas: locally we fight it because the initiative to introduce it comes with a huge violation of privacy |
| ketas | well s/passport/citizen id of some kind/ |
| medfly | I am pushing it into an oscilloscope directly |
| hagbard | and can you define insonsistent? why would it be varying in the first place? whats your signal source? |
| hagbard | whats the scope's input impedance? 50ohm or 1megohm? |
| medfly | it's a pretty good signal generator. I have tried it with a 1-2m cable and it doesn't cuse the same thing. |
| FreezingCold | ketas: mine is remote |
| medfly | cause* |
| medfly | I'm not sure |
| hagbard | look on the front of the scope. |
| hagbard | near the BNCs, it should say. it's important |
| medfly | 1M ohm. |
| Scott0_ | anyone know of a modbus master software? |
| tawr | brb |
| medfly | but it doesn't do this for the 1m cable |
| Scott0_ | I need one and I can't wait for a response from a guy in denmark :P |
| hagbard | medfly: well, i cant speak to that. i still think it's reflection. which would make sense, 10mhz is 30 meters and 16m is half that |
| medfly | hmm |
| medfly | could be. |
| hagbard | medfly: do you have a bnc T and 50ohm terminator you can put on? |
| medfly | yes. |
| hagbard | try it. |
| hagbard | because in my math just now i forgot to account for the velocity factor of rg58 which means 16m isnt as close to 1/2wl |
| ketas | medfly: privacy issues that arise from id, wtf |
| ketas | medfly: how come you could fuck things up like that |
| hagbard | ketas: i know, right? it's a transmission line ffs |
| Casper | What is a good single suply opamp for sensing shunt voltage? so need to have rail to rail input and a low offset.. expected gain would be around 100.. many opamp have a 4-10mV offset.. so half a volt or more of offset once amplified.. unacceptable.. |
| hagbard | uhh, AD8237 i think? |
| hagbard | !google analog ad8237 |
| hagbard | bah. |
| Casper | thru hole? |
| medfly | looks normal now |
| medfly | thanks |
| medfly | ketas: they want to take biometric data of each citizen and have it on the id |
| medfly | ketas: and also store all this data in a giant database |
| hagbard | medfly: wait, what? i was totally guessing. sweet. you're welcome? |
| FreezingCold | wtf, this chinese seller gave me a tracking number for a $3.40 product |
| hagbard | medfly: incidentally, everything i know about coax and transmission lines i learned from w2aew's channel on youtube |
| hagbard | Casper: i doubt it. |
| FreezingCold | that's a first |
| FreezingCold | oh, looks like it might be a fake? |
| hagbard | ? |
| hagbard | the tracking code? |
| hagbard | lemme guess, you just received the code and it doesnt apppear in the database yet. check tomorrow |
| FreezingCold | well it appears in this weird WeDo postal site |
| FreezingCold | but not china post.. which it was shipped from |
| theBear | WeirDo post eh, i like it |
| ketas | medfly: i'm not entirely sure how this is that bad.. so in addition to picture they also store fingerprint? |
| medfly | yes |
| theBear | did somebody say nightclub -> police state ? |
| medfly | and they also store this data in a database |
| medfly | which is a bigger issue |
| medfly | we don't trust government databases to remain secure |
| ketas | it would be fine without fingerprint? |
| theBear | and regarding reflections, propogation rates are different in various cables vs air |
| medfly | no the whole point of it being a digital ID is to have the biometric data |
| Casper | hagbard: do you knows of any thru-hole ones? |
| theBear | here it's privately stored and (usually) shared |
| ketas | medfly: seems wrong |
| theBear | just another good reason to start removing my fingerprints again |
| medfly | I don't understand |
| evilbetty | bleh |
| medfly | what on earth do you intend to store on a passport besides picture, information, and maybe biometric data? |
| theBear | i kinda wanna try that one where you cut them off then jigsaw them all up and sew them back together |
| dhrosa | medfly: nude pics |
| theBear | lol |
| ketas | medfly: though i don't get why this is bad? |
| theBear | but i was very young when i worked out which common household chemicals remove fingerprints effectively and much less painlessly than burning them off with acid every few months |
| medfly | biometric data also includes other things besides fingerprints |
| theBear | ketas, i don't like anyone having information about me in 2 or more categories, because i don't agree with all local laws |
| ketas | like what? |
| ketas | dna? |
| theBear | at least a dna fingerprint, i would guess |
| medfly | eyes |
| medfly | dna is too hard to obtain atm |
| theBear | err, it is ? |
| medfly | for millions of people? yes |
| medfly | too expensive |
| bulaia | i give dna samples for free |
| ketas | well, i still don't get it.. fingerprinta and more is just advanced picture |
| evilbetty | so does your mom |
| theBear | hey it's bulaia ! i just saw hawaii on tv and i thought of you |
| snuffeluffegus | You can be identified by like just 3-5% of your face being visible |
| ketas | it makes sense that id contains 'pictures' |
| theBear | ketas, in theory storing/sharing all that stuff impinges on your civil rights/freedoms, but in reality that's only an issue in the case of corruption or rule-breaking |
| medfly | if your bank thinks your fingerprint is an ID |
| snuffeluffegus | By your gait / posture / build |
| medfly | it would really suck if someone could just capture the meaningful info it uses to identify |
| ikarus | I've used keyboard timings when typing in specific texts as biometric ID |
| theBear | pfft, i can't be idenitfied that easily, and on paper i'm several ghosts |
| ikarus | works amazingly well |
| theBear | ikarus, you know macgyver can listen to someone type a password in the next room and workout what it is ! |
| medfly | could make it a hassle with police |
| medfly | they'd always pick up like 200 people whose fingerprints match up to something they found |
| ikarus | theBear: I've actually been tempted to write a system for that |
| medfly | that's not a normal and acceptable situation |
| theBear | medfly, well see in most countries that would fit somewhere between entrapment and 'the fifth' |
| dhrosa | I plead the second |
| medfly | you mean in the US and is police identifying your fingerprint in a crimescene not a viable reason for questioning everywhere? |
| ketas | medfly: stupid bank, then |
| theBear | ikarus, that reminds me, years ago now the fbi had a HUGE research project/results with some fancy nickname that was all about sniffing things like mains inputs and leakage off of random computer-ey cables for spying |
| theBear | medfly, no, i used a us term, which i quoted, and stand by my statement and wording |
| dhrosa | wait no, I plead the third |
| ikarus | theBear: the codeword for the counter for that is known as TEMPEST |
| medfly | ok, gtg |
| theBear | i don't think i know the third |
| ikarus | theBear: no idea what the applied one is |
| theBear | yeah, tempest, that sounds like something they would choose |
| ikarus | theBear: unlike the brits who are actually smart about codewords and randomize them |
| xDR1TeK | bye all |
| dhrosa | theBear: the third ammendment says that you're not obligated to house soldiers in your home in times of peace |
| dhrosa | actually at any time |
| theBear | i been considering and pre-experimenting a lot recently regarding some spying related stuff, including extensive work on derivitives and cures and approaches for things like the old 'listening' via a laser pointer on a window |
| evilbetty | is there ever peace anyway |
| dhrosa | it's a rather non-controversial ammentmend:p |
| dhrosa | ammendment |
| theBear | dhrosa, wow, really ? i bet it wouldn't work in times of invasion.. wars are all about the taking over peoples houses. have we learned nothing from the chronicles of yip man, hogan, or 'allo allo?' ? |
| theBear | oh i bet people like this 3rd, it sounds real nice |
| theBear | evilbetty, not when americans are involved :) |
| dhrosa | theBear: american civilians have no obligation to house soldiers |
| dhrosa | it's something that was more relevant around the time of the revolution :p |
| theBear | dhrosa, oh i believe you, and i understand your original wording, i just don't see it stopping the guys with guns from using your house |
| theBear | is it just re: local soldiers, or foreign ones too ? |
| dhrosa | local |
| dhrosa | can't stop foreign ones from barging in with guns |
| theBear | i wonder what the old geneva convention has to say on that stuff, or miranda |
| dhrosa | :p |
| theBear | don't care much, i just enjoy exercising my comprehension muscle.. an increasingly uncommon passtime in modern society, it would seem :( |
| theBear | i heard we have a constitution recently.. should probly findout what it says one day |
| theBear | of course this isn't proof of my willful ignorance, that's no secret, but it IS proof that you can learn a lot from television |
| theBear | i know all kinds of presidential terms and orders and quotes and crap from cartoons and the odd movie, but i don't even know who runs this country at the moment |
| dhrosa | theBear: the rich |
| theBear | i remember them popping up on tv a couple days ago and thinking 'heh, how about that, wonder when that dude took over' |
| theBear | pfft, if yer gonna be all thinking outside the box like that, nah, the rich here are too busy pretending they got culture to run anything.. people like me, and of course the bikies, run this country |
| FreezingCold | obama seems chill |
| FreezingCold | he cares too much about jobs though |
| corecode | shill |
| theBear | i do like that i seen him smoking and low-fiving a janitor dude |
| theBear | and he's way less offensive to the eye than the first-something-someone we got shortly afterwards |
| theBear | and to the ear |
| theBear | he's got a good smile |
| FreezingCold | theBear: low fiving sounds like an innuendo |
| theBear | heh, i like the boy ! |
| theBear | oooooooohhhh ahhh ! too soon ? |
| FreezingCold | smoking as in cigs or weed? |
| theBear | FreezingCold, err, in YOUR endo |
| theBear | lol, he's the president, noone's getting away with spreading pictures of him smoking weed all over the world :) |
| theBear | i'm a member of the pro-smoking lobby here since right around when they started.. i like smoke |
| FreezingCold | uh, there is a photo.. |
| theBear | it's almost bad enough to make me start voting |
| theBear | heh, that's even more awesome |
| theBear | and voting is compulsory at pain of prosecution here |
| FreezingCold | heh, I'm anti-pot |
| theBear | but err, i'm not aware of that |
| corecode | why? |
| corecode | FreezingCold: meaning you don't take it? |
| corecode | FreezingCold: or you think nobody should be allowed to take it? |
| theBear | FreezingCold, c'mon man, not everyone is awesome and somehow immune to the negative effects of alcahol like me |
| FreezingCold | corecode: Same reason I'm pro prohibition |
| corecode | FreezingCold: because it is ridiculous? |
| theBear | you WHAT !?!?!?! i dunno if we can be friends anymore, plus, i'm not sure i can trust a man who doesn't drink or smoke |
| FreezingCold | theBear: I drink |
| theBear | oh, so err, you against taxes then ? |
| FreezingCold | Totally |
| FreezingCold | But I'm also against social services.. |
| theBear | and that's why you into prohibition and against weed ? |
| FreezingCold | theBear: prohibition would have been great if it worked; it causes more harm than good. With weed there's still a chance of controlling it |
| FreezingCold | controlling = getting rid of |
| corecode | lol? |
| FreezingCold | cops are way too relaxed about it though |
| corecode | loonie friday |
| corecode | thursday even |
| FreezingCold | corecode: You disagree that alcohol is harmful to society overall? |
| corecode | FreezingCold: yes |
| JFK911 | corecode must be canadian |
| corecode | i do not have numbers |
| FreezingCold | corecode: What about all the deaths and lost working hours due to alcohol? |
| JFK911 | ive never met a teetotaler nuck |
| corecode | it does have negative effects on individuals, for sure |
| theBear | i'm very against social services tho in recent years i have taken into account that they kinda are necesarry in the case of crippleness.. assuming of course that we ARE a civilised people and don't want our sick to just starve in the streets.. at the same time, it makes me feel guilty even tho i had no hand in the matter, yeah, i don't really approve of social services at all |
| theBear | socialist hospitals and medicines tho, i'm into that |
| ossifrage | Anyone know of a company that sells LEDs smaller then 0402s? |
| corecode | but it might also have positive effects, like increased creativity, socializing, etc. |
| FreezingCold | theBear: the only social service I'm okay with is giving just enough to live plus whatever education you want |
| corecode | FreezingCold: you think society is just for working? |
| FreezingCold | theBear: I'm still on the fence about public health care.. I guess it's good overall |
| theBear | but alcahol has very positive effects for people like me, net and gross (so far so good) .. not to mention how psychotic and dangerous i am on (likely, not entirely proven due to time and health constraints) the medications that are supposed to help someone as crazy as me |
| JFK911 | theBear: what meds are you on |
| FreezingCold | corecode: No, but it's something you have to consider |
| Rab | ossifrage, plenty of companies sell raw dies. Mounting them might be a problem though. |
| JFK911 | your contention is a bit wacky theBear. ethanol, the positive poison |
| corecode | FreezingCold: i do not think so |
| theBear | FreezingCold, eduction i'm into socialism, but i don't feel someone who doesn't have a job should get ANYTHING, regardless if they quit, were fired, made redundant or anything else |
| ossifrage | Rab, the problem with wirebonding is the yield, especially for what I'm looking at doing (large LED count) |
| JFK911 | theBear: what if they are crippled. let em die? |
| JFK911 | theBear: what if they are crazy. let em commit crimes? |
| FreezingCold | theBear: the issue with not forcing them into education is then they usually turn to begging and crime (theft mostly) |
| Rab | ossifrage, makes sense. How large is large count, BTW? |
| ossifrage | Rab, rohm does have a picoled package 1mm x 0.6mm x 0.2mm, but thy are painful |
| FreezingCold | theBear: otherwise you have to have gated communities for the employed people like in africa =/ |
| corecode | no social net -> employers have too much power, de facto slavery |
| ossifrage | Rab, ~800 |
| theBear | JFK911, right now tapentadol and tramadol and paracetamol and codeine and pregablin and err, probly a few others, but i always been fairly high range classic manic depressive with fairly sociopathic tendancies |
| JFK911 | the issue is getting the right balance of rights, employers and landlords vs. individuals who may not be able to defend themselves |
| theBear | JFK911, well, that's tricky, cos i'm crippled, and if i die like i often want to it'll make some people sad who don't deserve it |
| FreezingCold | corecode: I think we're moving more towards an individualism market; each person has to be looking out for themselves and marketing themselves correctly |
| corecode | FreezingCold: why? |
| corecode | because you say so? |
| JFK911 | theBear: arent those all for pain? codeine can be fun if you take a bunch of it, but if its mixed with paracetamol you dont want to take a whole bunch |
| FreezingCold | corecode: [14:41:41] <FreezingCold> corecode: I think |
| FreezingCold | I have no facts to back that up |
| FreezingCold | zero |
| FreezingCold | na-da |
| theBear | JFK911, but if i don't become usefull again in a year or two i ain't gonna be happy about the idea of a lifetime pension, deep down i think i feel the useless SHOULD just die |
| ossifrage | Rab, the other problem with wireboding is protecting the bond wires, not sure how well they would survive a silicone overmold |
| JFK911 | theBear: it's difficult idea to grasp if you used to be 'productive.' but you arent a robot, anyone who criticizes you for not working is a dick |
| theBear | JFK911, yeah they are, i stopped taking/trying different (VERY time consuming due to slow onset and weening times) antidepressants and similar things over 10 years ago now |
| corecode | ossifrage: what are you trying to do? |
| JFK911 | theBear: yeah psych rx are very disruptive and definitely not for everyone. cannabis actually has comparatively few side effects |
| theBear | JFK911, i know i'm a dick, but that's how i feel.. not that i'm shit for not working, but that me or anyone else doesn't deserve a free ride just 'cos they're of little value |
| JFK911 | there is a theory of cannabis induced psychosis though. |
| theBear | JFK911, heh, i know that too, but both with prices and age, i'm back to almost exxclusively alcahol these days |
| ossifrage | corecode, working on a discrete LED display |
| JFK911 | theBear: You paid taxes your whole life. Therefore you should regret receiving government services *less* |
| theBear | and i'm 99.999% psychosis proof |
| corecode | ossifrage: maybe china can help you? |
| Rab | ossifrage, I've seen wirebonded LED strip assemblies which suffered dramatic failure rates. The boards (IMS) could flex, and there was a clear flexible overmold of some type. The bond wires just couldn't take it. |
| cheater | Rab, have you finally killed your efnet troll cave dead enough that you are forced to seek new pastures? |
| corecode | they have a lot of bonders |
| JFK911 | theBear: Unlike someone who washed ashore you actually contributed |
| Rab | cheater, what a pleasant surprise! |
| theBear | JFK911, meh, there's roads and hospitals and modest-co-pay medications, buses and trains and shops and whorehouses and parks.. pissed off with the hundreds of thousands too lazy/stupid to get work that get a free ride on it tho |
| JFK911 | theBear: here in usa its rather difficult to get a 'free ride' |
| synx508 | and there are no social problems in the USA as a result! |
| theBear | and i try to be useful, i sure spend a lot more time helping here whiel i'm subsidised, but my usefull doesn't makeup for my food costs |
| cheater | Rab, I will not give in to your trollology |
| ossifrage | Rab, that is my thought, gluing raw die to flex and then wirebonding them, bending that assembly around a support structure and then injection molding silicone over the top would have a pretty high fail rate |
| JFK911 | theBear: ive seen how much they'd give a person, and compared to minimum wage, it doesn't seem like fun |
| Rab | cheater, good for you. |
| JFK911 | now there are people who lie and cheat it, and live it up |
| synx508 | in the UK we call those people politicians |
| JFK911 | you can't have an expensive car and get food benefit, for instance, but i've seen people pay with a benefit card and in the grocery parking lot they have an old car with a fresh glittery paint job and $5000 wheels |
| ossifrage | So I'm back to finding the smallest possible packaged LEDs |
| theBear | JFK911, maybe, but over here it's so damned easy that people with real quantifiable medical problems like me have to do quartely face to face interviews to check we aren't cheating the cripple system, regular people who just quit or got fired get nearly as much indefinately with nearly no scrutiny outside of getting a few random business owners to scribble that they failed an interview now and again |
| Rab | ossifrage, but larger than Rohm PicoLED-mini? Or cheaper? |
| cheater | ossifrage: at that point you're looking for bonding wire that can flex well enough. The metal needs to be soft enough, and the enamel needs to take flexing as well, and be chemically resistant to what you're molding it into. |
| JFK911 | theBear: this must be frustrating to see. |
| theBear | JFK911, heh, quick head maths say that even with modern fulltime (32-38 hour weeks ? pfft !) on the full disabled pension with medicine and similar little additions, and considering that min wage here for most jobs at an adult age is pretty decent, i'm at about half that income |
| ossifrage | rab, I have no clue what the high volume price of the rohm picoleds would be, the factory in china I'm working with is very closed lipped about component pricing |
| theBear | JFK911, meh, don't shoot the messenger, they let me reschedule when i can't actually walk/etc to get there, i'm just grateful i ain't starving and am relatively comfortable (at least pain wise) |
| ossifrage | cheater, I suspect that wirebonding is beyond what the factory I'm working with could handle |
| theBear | the social system is actually quite painless here if you can just be polite and honest and not be screaming and swearing and having a punchup with your defacto and kids while yer at the office |
| JFK911 | they say cannabis also works for pain but i never experienced this effect myself. i think i had a toothache once and it didnt help any |
| theBear | apparently that isn't as easy as i make it sound, 'cos 99/100 people you see there act that way, but i have no problem with it |
| bulaia | depends on the person and the pain |
| bulaia | it's both worked and not worked for me |
| JFK911 | yes i probably had the wrong kind of pain. i can see that it might help for gastrointestinal problems |
| cheater | ossifrage: oh, i thought you said you wanted to do it yourself. |
| bulaia | when it works it's less of a painkiller and more of a pain distraction |
| theBear | JFK911, some pain it helps more than others, and a lot like codeine and light opiate doses in general, it's as much letting you ignore it more easily as it is taking it away |
| JFK911 | i like codeine as a sex aid |
| ossifrage | cheater, no this is not something I could do myself |
| JFK911 | just a little numb, then the fun lasts for hourrrs |
| JFK911 | make wife happpy |
| cheater | ossifrage: i've seen people do 3d pcbs at productronica 2014 |
| cheater | but that's expensive. |
| theBear | tooth pain it never helped me, but on a good day if someone shares a joint with me, i often notice that everything doesn't actively hurt for a change, which is awesome |
| JFK911 | theres no really good reason for it to be banned |
| JFK911 | if i drink i get sick and act stupid |
| theBear | JFK911, hehe, no shit, good idea :) i used to (and still technically do, i assume <grin>) use a similar approach but based on more partydrugs than codeine |
| ossifrage | cheater, at one point I was messing around with discrete led displays on my own, but now I'm doing it for an actual product |
| JFK911 | im going to try the e cigs instead of real tobacco soon, hopefully it might help with quitting |
| Polesch | How can I tell if my variac has isolated outputs or not? |
| theBear | if i drink i feel less painful, and can concentrate and can explain things better, and even just sometimes, exhibit aritificial empathy, which is impressive when you don't like msot people or society, and are 95% sociopathic naturally |
| theBear | Polesch, you asked that yesterday ! these guys are useless ! |
| Polesch | I did not ask that! |
| theBear | Polesch, erm, easy way i spose would be to unplug it and measure resistance from input to output socket/jacks |
| theBear | oh, someone did |
| Polesch | I just asked what it was |
| theBear | like, word for word |
| Polesch | I found a variac online yesterday, someone local, just bought it without knowing much about it |
| cheater | ossifrage: so you want to do a flex pcb then? |
| theBear | 'Sep 04 04:19:29 <Ammonia> If a variac is said to have 'isolated outputs' what does that mean?' told ya |
| The_Coolest | https://www.adafruit.com/product/2086 |
| theBear | not you tho |
| theBear | don't advocate flex-anything ! they're too effed ! |
| Polesch | theBear, I am Ammonia aswell. |
| theBear | also most variacs only have a single output |
| theBear | woah dude, tricky |
| ossifrage | cheater, yeah LEDs on the top side of the flex, drivers on the bottom (with underfill) |
| Polesch | The resistance across the outputs on my variac is 3.3-3.5 Ohm |
| Rab | Polesch, what's the resistance between input and output? If it's truly isolated, there should be virtually no reading. |
| theBear | heh, that's a cool little kit@adafruit.. and for reference, basically EXACTLY what they hide in potting compound (that makes the component physically unsound also) in those $200+ 'opamps' with those silly audiophool mic preamps |
| Polesch | I can try that |
| theBear | Polesch, what rab said, no one said across one side |
| theBear | tho without thinking too hard or reference material, technically a variac can't be isolated |
| theBear | that'd have to be a variable transformer, where a variac is from memory a 'variable autotransformer' .. kinda like a tapped inductor, half a trannsformer |
| theBear | heh, less than meets the eye |
| Polesch | I get no resistance measurements across input and output |
| Rab | Polesch, here's a schematic of a typical variac: http://www.afcaforum.com/attachment.php?id=53771 |
| theBear | that sounds isolated |
| Polesch | It did flicker to 300 M Ohm once, but OL on both |
| theBear | mmm, that schem agrees with what i said poorly a couple lines back |
| Polesch | I do have a nanosiemens function, can try that |
| Rab | Might have an added winding for isolation, or something. |
| theBear | and that flicker on the meter is likely just a cap or maybe a mov or something, just there to stop the output side floating to silly voltages on its own, and generally make the thing legal |
| Polesch | Slightly unrelated, but do anyone know why multimeters have problems measuring resistance across large inductors? |
| theBear | Rab, sounds like it, tho i maintain that technically a variac is that schem, and therefore cannot be isolate |
| theBear | d |
| Polesch | The seller online said the variac had isolated outputs, but I can't find nay markings or text on it that would indicate such |
| Rab | http://www.amazon.com/Variac-Variable-Transformer-Isolation-1000va/dp/B006NGC6HU |
| Polesch | I only see that the output is protected with a fuse |
| theBear | Polesch, erm, i haven't noticed particularly, oh, you probly mean large value, not large physically, but it'd have to do with the approach/timing the meter uses to 'probe' resistance, and the inductor fooling it |
| jpa- | most people aren't that careful between the difference of 'variac' and 'variable transformer' |
| theBear | heh, i always liked the classic red variacs like that |
| Polesch | Right, I have no idea on the differences |
| theBear | hmmm, good price on deoxit d5 |
| Polesch | This thing is made in Sweden anyway |
| Rab | Polesch, can you see a brand/model number? |
| Polesch | Yeah, Lübeck Vario SR54-220/260T |
| theBear | i can almost see it from here |
| theBear | hmm, are those us sockets on a 220/260v variac ? |
| Polesch | Standard European, but made when we had 220 VAC mains instead of 230 |
| cheater | ossifrage: you could perhaps use a display lens, the display will be smaller on the front panel than it really is |
| cheater | it's just a wedge of clear plastic |
| theBear | wow, euro has a standard plug eh ? that new with the new money or i'm just dumb ? |
| cheater | fairly thick |
| cheater | theBear: definitely dumb. don't even ask. |
| ossifrage | cheater, think wearable device |
| theBear | cheater, aww, you could be nice about it :( |
| cheater | ossifrage: external or internal? |
| Polesch | Rab, the model number on the device is 'TYP 237', the other model was the transformer itself |
| ossifrage | LOL |
| cheater | theBear: don't want to give false hopes. |
| theBear | being dumb definately makes me smile |
| cheater | :) |
| theBear | that's more like it |
| jeremyabel | godddammmit linear technologies why are your parts expensive |
| cheater | Polesch: if you open it up, you should see two transformers, one is round (that's the variac) and one is rectangular (that's the isolation transformer) |
| Polesch | Only one big one here |
| jeremyabel | 'oh, this one fits my specs perfectly! oh wait it's 2x the price of the previous solution I was using..' |
| theBear | perhaps my only real life goal that sticks thru the years is giving myself enough braindamage to be as unaware and happy as those assholes i see walking in the street |
| cheater | pic? |
| Rab | Polesch, I can't find anything online..sorry. |
| cheater | Polesch: i wouldn't trust it to be isolated. But maybe you're not seeing part of it. |
| ossifrage | cheater, the design actually may use the structural frame as a light guide/mask |
| veek | man! quite a few chinese shipping agents are absolutely rotten and deceitful! that lying biatch tried to rip me a new anus! FYI: Ocean Freight is around USD 15/cbm/RT (cubic meter or 1ton which-ever) which is really low and this money goes to the carrier; what gets you are the DOCumentation charges for the B/L (bill of lading) USD 50 supposedly (but that's for a whole container) what a NVOCC issues is a House BL; |
| theBear | Polesch, i really can't think of anything that your earlier measurements wouldn't notice, i suppose you could grab your nearest huge dc supply or battery, and see if you can put a huge offset on the output side of the thing without all yer breakers exploding |
| ossifrage | but my big issue right now is figuring out how to get the pixel pitch down to the bare minimum |
| theBear | veek, that IS cheap ! |
| veek | theBear, untill they sprout you a new anus which is why its cheap |
| cheater | ossifrage: not with discrete devices, i believe. |
| veek | actual FCL containers are around USD 800-1300 and more. USD 15/RT is the bait |
| theBear | meh, i go about things in non-recommended ways.. only time i ever needed/used BIG (by the cube) shipping the international container yard and several companies headquarters were literally in my backyard, i had a mid level employee for hints and tips and intros, and i dealt directly with the last company in the chain, the one that owns the trucks and decides what goes in them and where |
| theBear | so to sum up, NOONE rips a new anus on the bear, and i got no idea, i believe you |
| FreezingCold | veek: what do you import? |
| theBear | on reflection, if i leaned right forward the thing the doctor made in my back would look a lot like a first vagina, or right now like a 'circumsized' vagina |
| theBear | heh, that's abit graphic, sorry |
| veek | FreezingCold, nothing thank the lord! |
| FreezingCold | veek: ah, what caused the curiosity into the prices? |
| theBear | also female 'circumsision', NOT cool |
| cheater | theBear: porn or didn't happen |
| theBear | and hard to spell |
| theBear | nah, still too dopey to get pictures all the way from a phone in my pocket to the server in the next room, maybe later |
| theBear | later in the year that is |
| jeremyabel | http://www.st.com/web/en/resource/technical/document/datasheet/CD00000460.pdf so I'm trying to understand this comparator here |
| jeremyabel | on page 8, typical applications, figure 8 |
| veek | FreezingCold, and they don't tell you about destination port charges either. that's even trickier - you can get hit real bad for USD 100 compulsorily (you have to pay - it's got to do with the D/O [some sort of order]) |
| theBear | for a bit i had this amazing overly configgable any-transport-you-can-think-up syncey thing working on my phone, but those days are long gone |
| jeremyabel | if +Vref > -Vref, then +5V appears at Vo, is that what's going on here? |
| FreezingCold | veek: so how much would a full 40 foot crate cost to ship to miami? |
| dn4 | how easy is it to product half a million volts? |
| dn4 | s/product/produce |
| jeremyabel | at what current? |
| theBear | i looked up my bigbrother logs a few months ago, i got my location/height/batt % and reception everywhere i went for the past several years in 15 min intervals in there |
| jeremyabel | you can just rub some balloons together to get some major kilovolts if you want :P |
| theBear | dn4, pretty easy to produce, tricky part is stopping it from turning into lightning and getting away |
| theBear | jeremyabel, i'd rub them on my head, cos i like to live dangerously :) |
| jeremyabel | you rebel you! |
| veek | FreezingCold, well i wanted some l00t and i though i'd buy 1/2 a kg as a trial so i enquired. your better off buying FCL AND don't ever tell them you are an individual - cook up some company (so much for honesty is the best policy) |
| jeremyabel | theBear: you up on comparators? |
| theBear | without a cause, all i need is a tight white shirt and a olde motorbike |
| jeremyabel | lol |
| theBear | jeremyabel, mmm, above average |
| jeremyabel | trying to understand them |
| jeremyabel | http://www.st.com/web/en/resource/technical/document/datasheet/CD00000460.pdf |
| FreezingCold | veek: they do something as small as half a kilo? What's FCL? |
| theBear | keep questions simple tho, definate subconscious responses, i can't think on all these pills |
| veek | FreezingCold, dunno about 40' but the FCL quote i got for 20' from Evergreen was. umm USD 800-1300 i think let me confirm |
| jeremyabel | page 8, figure 8, can you explain what that's doing? |
| jeremyabel | I understand it's comparing +V and -V |
| theBear | mmm, the old 339 eh |
| jeremyabel | indeed |
| jeremyabel | I'm looking at the 239 but I guess it's the same |
| JFK911 | veek: does that include brokerage and everything else? |
| FreezingCold | veek: not bad |
| JFK911 | shipping is hard/hassle |
| jeremyabel | theBear: not really sure what the diff between 139, 239, and 339 are |
| theBear | umm, they're a lot like an opamp but notice page 2 fig 2 that you got an 'odd' output, in this case a common collector aka npn to gnd, sometimes/often there is also a diode, internal or discrete, that's why they got the pullup in that example |
| jeremyabel | temp range it seems |
| FreezingCold | what rocks about ordering directly without a shipping container is that you don't usually pay customs |
| FreezingCold | here in canada the postal people just say 'fuck it' |
| FreezingCold | takes them too much time to read every package |
| FreezingCold | so they only do it for large shipments |
| theBear | jeremyabel, it'll be on there somewhere, but pretty sure it's hmmm, nah, what you said |
| veek | FreezingCold, O/F：USD850/1300/1300, subject to DIH、CIC/D |
| jeremyabel | theBear: at the last page or so |
| jeremyabel | page 17 |
| theBear | FreezingCold, don't you mean fuck eh, buddy ('you're not my buddy, friend !' 'i'm not your friend, guy !') |
| jeremyabel | 139 are -55 to 125, 239 are -40 to 105, 339 are 0 to 70 |
| theBear | jeremyabel, yeah got it, usually last page or specs or title explain that kinda multi-p/n stuff |
| FreezingCold | theBear: they say 'fuck it' in reference to your package, not you |
| hjf | i finally replaced that stupid HDMI cable |
| hjf | http://i.imgur.com/l6VbrHX.jpg |
| hjf | more dramatic version: http://i.imgur.com/etH0b3W.jpg |
| theBear | FreezingCold, oh, i meant that in regards to a package |
| FreezingCold | =/ |
| theBear | i know if i was canadian i'd say buddy and house and eh ALL the time |
| jeremyabel | theBear: now what's LT's version of the 339.. so I can plug it in to ltspice here |
| jeremyabel | need to figure out my reference voltage |
| theBear | jeremyabel, ummmmmmmmm, i dunno, i only use linear for those special one-of-a-kind chips, everything else i use the most commonly available (which also usually means i got them already) |
| jeremyabel | darn |
| theBear | type comparator lt into something with google autocomplete |
| theBear | it's my new favourite net-info-wrangling trick |
| theBear | hehe 'if you die in canada do you die in real life ?' gotta love the autocomplete |
| evilbetty | ok |
| jeremyabel | lol |
| jeremyabel | theBear: http://ltwiki.org/?title=Adding_a_permanent_component_to_LTspice well this works too! |
| theBear | hangon, are you telling me the lt in spice stands for linear tech ? |
| theBear | and look at that, it's a synonym for the 3rd result in my not-web-search |
| theBear | damn i'm amazing |
| jeremyabel | :P |
| jeremyabel | are you a wizard? |
| jeremyabel | bearwizard |
| hjf | hah my cousin's husband is an idiot |
| theBear | hehe i'm like osama, a kinda dirty wizard santa claus character |
| hjf | i mean the guy is completely useless. he doesn't know how to even operate a DRILL |
| FreezingCold | hjf: of course, he married into your family |
| theBear | oooh burn ! |
| hjf | the guy can't drill a hole in a wall, jesus |
| hjf | the guy is only child from a rich family |
| FreezingCold | I don't see what's wrong with that? |
| hjf | so he's just an overall douche |
| FreezingCold | he's just never done it before |
| hjf | FreezingCold: yes but he doesn't want to |
| theBear | well that's cool, tell him to use his inheritance to pay someone useful, like you to drill the hole |
| hjf | my cousin is a lot. a LOT wealthier than him |
| FreezingCold | hjf: maybe he isn't as dumb as he seems then |
| theBear | course he doesn't .. it's noisy and he might get dust on his crocodile polo shirt or his tennis shoes ! |
| hjf | like, the guy's father have a store in some town, |
| hjf | my cousin's father owns the largest electronic retail store int he country with like 350 locations |
| JFK911 | wow |
| theBear | does it sell those crocodile polo shirts ? it's been too long, i need one again |
| jeremyabel | lol |
| hjf | but guess what |
| hjf | my cousin |
| FreezingCold | hjf: you should have married her first, you probably knew her first too |
| theBear | hehe |
| hjf | a woman obviously.. SHE CAN DRILL A FUCKING HOLE |
| FreezingCold | okay, I'll stop myself there |
| hjf | so anyway |
| FreezingCold | hjf: I'm so tempted to make a drilling joke.. But I'll hold myself back |
| theBear | speaking of women, and drilling effing holes <grin> nah, too easy |
| hjf | he comes today to ask me about fiscal receipt printers |
| FreezingCold | ha, theBear couldn't resist |
| hjf | and tells me he wants to start a business |
| jeremyabel | loool |
| theBear | fiscal receipt printers, as opposed to those regular receipt printers eh |
| FreezingCold | hjf: argentina IIRC? |
| hjf | theBear: yes, they are special here in .ar, obviously. they have a ROM |
| theBear | err wha ? why |
| hjf | theBear: you get LX-300 OR LX-300F which costs 10 times more cause of that ROM |
| jeremyabel | wtf is in the ROM? |
| FreezingCold | hjf: I doubt it, but ever been to Panama? |
| theBear | here you just buy any one from any company in the world, stick in your logo and *bam* |
| hjf | theBear: so all receipts you print are stored in ROM |
| hjf | FreezingCold: no |
| hjf | so anyway |
| theBear | pfft, i bet che never had a rom in his receipt printer |
| hjf | the guy asks me about that |
| hjf | because he wants to start a business |
| hjf | and not worry about stock |
| hjf | he will have employees |
| hjf | a stock control software |
| hjf | so he doesn't need to go to work |
| hjf | and just go to the store like once a week to check the stock |
| hjf | .. |
| theBear | meh, people ask me about taxes, i never even done a return, but i still know all about it.. there ain't no helping fool |
| theBear | s |
| jeremyabel | lol |
| hjf | this dude is like 30 |
| hjf | never worked in his life |
| FreezingCold | hjf: that goes for most graduate students too :p |
| theBear | i'm like 30(ish) and i may never work again in my life :( |
| theBear | lol |
| hjf | and he wants to start a business.. but not go to work |
| theBear | FreezingCold, they get what he said AND what i said :) |
| hjf | i was there the other day with them and he comes out and goes like |
| FreezingCold | theBear: man I still don't get why you aren't able to find tons of work online, you're a smart dude |
| hjf | oh they called us from HSBC they want us to go talk about some investment proposal |
| theBear | thats how rich people think, spend money to make money, actually do ANY work for that money ? out of the question ! |
| hjf | and i go like. is this guy for real? |
| hjf | and say 'ah yes, investment funds. i have my money on that. i'm getting 180% annual return' |
| hagbard | 180%? really? |
| hjf | fuck you, asshole. you think you're something? dude you never worked in your life. i live off dad's money too but at least i can drill a hole |
| theBear | FreezingCold, cos i can't sit anywhere i can type for very long, some days more than others, and i ain't as sharp in my conscious thinking or as fast generally as i should be |
| hagbard | 0001ACTION thinks . o O ( bullshit. )0001 |
| hjf | hagbard: yes when economy is in shit, you get those crazy numbers |
| hjf | hagbard: we have like 40% annual inflation |
| FreezingCold | hjf: heh, that's risky then |
| theBear | damn ! that's almost as much inflation as my marlboros |
| hagbard | hjf: the economy's been shit for 80 years, the only way people get those numbers is by stealing, fraud, or scam. |
| FreezingCold | I checked, I can get like a 20% interest rate on a month to month basis if I put my money in an iranian bank :p |
| theBear | hmm, how they drive that much inflation ? govt got the old cash-photocopiers running fulltime or what ? |
| hagbard | I'm just barely old enough to remember australes. |
| FreezingCold | theBear: how long do you manage to spend on IRC? I'm not telling you to leave us, but you seem to be able to spend a bit of time here? |
| hjf | theBear: 100 billion pesos las month |
| theBear | FreezingCold, getting better recently, but i can never sit more than maybe 20mins without at least a little walk and a stretch, and if i do it takes a lot more than that to get back to not very uncomfortable |
| theBear | hjf, holy eff balls ! |
| FreezingCold | theBear: how about a tech support job? |
| hjf | hagbard: http://www.fondosalpha.com.ar/Site/frmFactsheets.aspx |
| FreezingCold | theBear: you can be a bluetooth headset douchebag! |
| theBear | mmm i dunno, i hate people, and windows, and ain't fond of osx |
| hjf | hagbard: click on 'alpha acciones' and see the evolution of that thing |
| bobo1on1 | you basically hate everything |
| theBear | traditionally employers have been wise enough to keep me away from customers as much as possible, it just works better that way |
| theBear | bobo1on1, nah, just common os's and ya know, humans |
| R0b0t1 | animals |
| R0b0t1 | animals are nice and predictable |
| theBear | i like flowers and animals, and musics |
| R0b0t1 | people? nah. |
| hagbard | hjf: wow, that's the first time I've seen someone embed a PDF in a webpage. |
| bobo1on1 | ok, just let me know if you develop a fond hatred of spoons for example |
| jeremyabel | theBear: whatcha listening to these days? |
| bobo1on1 | or sand |
| jeremyabel | lol |
| bobo1on1 | nobody hates sand |
| theBear | bobo1on1, no way man ! |
| jeremyabel | theBear loves his spoons |
| theBear | jeremyabel, ummmmm, been a bit lazy but i think i'm still on the various obscure and 'classic' techno bits and pieces i got off a backpacker buddies hd |
| FreezingCold | theBear: you do any Android dev stuff for fun? |
| jeremyabel | word |
| theBear | i think i can still play the spoons if it helps |
| hagbard | FreezingCold: What do you do for fun? |
| theBear | FreezingCold, haven't quite set up the full dev env and hello-worlded yet, but i know the os/linux side of things, and manufacturer eccentricites almost inside out these days |
| FreezingCold | theBear: want a $10 contract? :p |
| theBear | tho in most cases i do have reservations about charging for software, even a couple bucks |
| jeremyabel | theBear: why? |
| jeremyabel | it's your effort, you should get paid for it |
| theBear | umm, if you don't demand a tax-invoice, and can get the money into the country, meh probly, but until i get over this surgery i am dangerously stupid |
| jeremyabel | how's getting over the surgery going? |
| FreezingCold | theBear: uh I listed it through elance |
| hagbard | theBear: Donations into a paypal account may work well enough. Leave the money in the paypal account and use it whenever you need to buy something that accepts paypal? |
| theBear | jeremyabel, other people do similar effort and thus all these computers and devicey things surrounding me work for free, like technical/general knowledge, i always kinda felt instinctively that software should be free |
| FreezingCold | theBear: elance can go through paypal |
| theBear | mmm, gettin there, gotta walk and irc a bit less this week, but basically aight |
| hjf | hagbard: you know Soda Stereo? |
| jeremyabel | theBear: might I ask what it was surgery for? I'm not up on your medical issues, I guess |
| hagbard | no, I'm sorry. |
| jeremyabel | if you're comfortable sharing |
| theBear | mmm, i got half a paypal account, got pissed off between the not accepting a prepaid credit card and the problems people have had |
| FreezingCold | hagbard: read a lot |
| theBear | but when i smart enough to program, i'm smart enough to work that out |
| FreezingCold | hagbard: plan different ideas/concepts that probably won't happen, but fun to think about |
| FreezingCold | theBear: I think you can link your bank account |
| hagbard | theBear: You have to accept that paypal doesn't want to be laundering money or hiding money for terrorists. |
| FreezingCold | theBear: you don't need a credit card for paypal, you can use a Visa Debit card fine |
| hagbard | theBear: But, yeah, I can appreciate that being obnoxious. |
| hagbard | FreezingCold: I think he meant someone was trying to pay him, with paypal, using a prepaid credit card? |
| theBear | yeah, until people get bored of it i don't mind repeating things (you repeat yourself a LOT in hospital land, like whole story to every person you see).. had some err, laminectomy and a big micro discectomy bout 3 weeks ago |
| blocky | if i want to simulate analog circuits (<10 transistors, to start with) from linux via command line and editing netlists, which spice do i want to use? |
| jeremyabel | gurpgork: niiiiice |
| Netwizard | https://i.imgur.com/zzlzHKR.jpg |
| Netwizard | soooo |
| Netwizard | good or bad? |
| theBear | FreezingCold, mmm, in my world visa/mastercard is 'creditcard', regardless of modern realities, and if it comes to it they can probly have my 'can afford to get screwed' second visa numbers, but i'd kinda rather not.. their modern terms document is ridiculous, as is their treatment of all kinds of people/things they don't approve of |
| R0b0t1 | blocky: There's basically one spice with a bunch of front ends. |
| FreezingCold | hagbard: an easy trick if you live in tourist city is to go to the currency printing/mint and buy coins at face value with the card; then go to your local bank and deposit them |
| theBear | blockh34d, probly ngspice, but basically what R0b0t1 said |
| FreezingCold | theBear: just link a debit card and a bank account. Make the debit card attached to the same bank account you like, then you're only risking one account |
| theBear | FreezingCold, so um, what kinda job would it be if i'm compis mentis before someone else does it ? |
| blocky | are any of them free? |
| blocky | or do i need to bug someone in the university to get me a license |
| FreezingCold | theBear: I had it listed for two weeks and nobody submitted a decent proposal. I'm trying to find/make a logo.bin file to flash on my nexus 7 that hides the stupid 'unlocked bootloader' logo thingy. I got a logo.bin from my Moto G that does that, but I doubt they're the same |
| hagbard | blocky: I think some of them are. |
| theBear | FreezingCold, yeah, that's what i said :) and i only put JUST enough cash on it anytime i'm expecting a charge, partly for protection, and partly cos i got pissed off at utilities and isp kinda companies that insist on visa/auto-charging instead of billing even their longtime customers, and moreso the way that i would put 20bucks on the card, walk up to the shops and find the isp had grabbed it with their monthly random-time-charging |
| theBear | FreezingCold, interesting, you mean in the hboot screen right ? |
| FreezingCold | theBear: yeah I think that's it |
| theBear | hmmm, i didn't know you could have a logo OR overwrite that, but remind me when i forget, i like little challenges like that, and due to my electronics background, often find that level stuff more straightforward than computer dudes |
| hagbard | theBear: I'm similar to you in that regard. |
| theBear | why you wanna do it ? to sell, or just cos you don't like it showing that or what ? |
| FreezingCold | theBear: I don't get how it works, because somehow the stock logo.bin detects the bootloader is unlocked or something |
| theBear | FreezingCold, we talking normal boot or when you hold maybe vol up and power and get a text only bootloader kinda screen ? |
| FreezingCold | theBear: the normal boot that says 'Google' |
| theBear | i never seen a nexus up close, but ooooh, ok, that should be way easier |
| theBear | you tried just a generic startup animation replacer ? an app that is |
| theBear | oh actually, at a guess it doesnt' detect it, it just prints it on top |
| bobo1on1 | I wish samsung would release android 4.4 for my galaxy s4 mini already |
| bobo1on1 | bluetooth a2dp is fucked on android 4.2.2 |
| theBear | hmm, getprop might show something |
| R0b0t1 | Can you even do that? I thought the firmware was supposed to make it impossible to tamper without leaving a mark |
| R0b0t1 | without serious RE |
| hjf | guise |
| hjf | where can i buy litz wire |
| hjf | but in like |
| hjf | small quantities |
| R0b0t1 | the internet |
| hjf | like 200 grams or so |
| bobo1on1 | ebay? |
| theBear | bobo1on1, last week i got REAL carried away with a galaxy ace/cooper, tried everything from stock 2.3.x's up to 4.4.? and at the moment sitting on a 4.3.something that does awesome bt keyboard, which is rare in any version and config |
| hjf | bobo1on1: i need it to be a real place that can give me a receipt |
| bobo1on1 | oh |
| theBear | a lot of ebay sellers are real these days |
| theBear | othwerwise electronical places is where i'd try, like rs/farnells/etc |
| FreezingCold | theBear: I think even my HTC Incredible got 4.x or something insane |
| bobo1on1 | you can just print out the paypal receipt |
| hjf | bobo1on1: no like, it cannot be the paypal receipt, it has to be a real one |
| hjf | for customs bullshit |
| bobo1on1 | oh |
| theBear | FreezingCold, haven't even setup the big/fast new sdcard i got, but hot damn it's running fast and smooth and comfortable on teh 4.3 nice and cutdown.. and it's a LOW spec phone |
| hjf | thats why i can't order from china |
| R0b0t1 | hjf: What makes it a real receipt? |
| R0b0t1 | The law has to say somewhere, certainly? |
| R0b0t1 | Packing slip might/usually count(s). |
| hjf | R0b0t1: it has to have the name and address of the seller and some tax id |
| bobo1on1 | I get a ridiculous amount of 'free gift' packages from china :) |
| theBear | in this country just scribbbling 'tax receipt' and a business tax-reg-no somewhere on it makes it official |
| ShadowJK | hm |
| ShadowJK | I shouldn't go to exhibitions |
| ShadowJK | now I'm pondering buying 3 fluke meters :o( |
| theBear | hmm, maybe i can smuggle electronics and hitech gear into argentina for a living |
| chris_99 | haha bobo1on1 |
| hagbard | theBear: In his country, any opportunity an official has to potentially get a bribe or some kickback, they'll probably accept it. |
| hjf | theBear: in this country you have to get your receipts (factura) printed at a registered print shop, |
| theBear | i don't bribe, i take pride in my rule bending |
| theBear | hjf, ooh, maybe i can borrow your cousin in laws fiscal printer :) |
| R0b0t1 | hjf: lolwhat |
| hjf | theBear: the print shop will go into the tax agency's website and request an authorization to print receipts for you |
| cheater__ | hagbard: what country is that? |
| evilbetty | why not export to a country where the ppl can actually pay you :p |
| R0b0t1 | that is patently ridiculous |
| hjf | evilbetty: you have to pay to export...... |
| R0b0t1 | I really wonder what their justification was for requiring print shops to be authorized. |
| FreezingCold | theBear: anyway, just find a 1920x1200 logo.bin with the stock google logo; as long as the bootloader unlocked logo below disappears, I'm happy |
| hjf | R0b0t1: receipts are numbered |
| hagbard | cheater__: It's the continent, really. South America. |
| theBear | why not live on the couple feet of spare room near the tv and pay rent in beer and cigarettes |
| R0b0t1 | I mean, if I qualify something as official, even if I wrote it, that just means it's easier for me to perjure myself |
| theBear | FreezingCold, that's what i was saying, i don't think it will, the logo is printed OVER anything, then again, that's just a SLIGHTLY educated guess |
| hjf | R0b0t1: i could go into many print shops and just print the same number receipts several times, and keep a 'real' one for tax purposes and give fake receipts to my clients |
| FreezingCold | theBear: it somehow disappeared on my moto g; let me DCC you the stock and replacement logo |
| evilbetty | dcc lol |
| theBear | hmm, i let you try, but i think my dcc forwarding is still broke |
| evilbetty | i suddenly feel in the 90s |
| bobo1on1 | I use a client that does not support dcc :) |
| FreezingCold | theBear: see it? |
| hjf | btw a receipt is an actual form |
| theBear | unless you're not nat'd |
| R0b0t1 | hjf: So you're telling me the revenue service isn't smart enough to figure out fraud with copious hand-holding? |
| hjf | not just any piece of paper |
| theBear | mmm |
| hagbard | FreezingCold: Nexus 7 or Nexus 7 (2013) |
| R0b0t1 | without* |
| evilbetty | does dcc work for anyone with a nat router and no manual changes to the irc client settings |
| FreezingCold | hagbard: 2013. |
| bobo1on1 | evilbetty: no |
| theBear | yeah, they all failed, hmm, 403 forbidden ? wait |
| evilbetty | and afaik since the 21st century everyone has a nat router |
| FreezingCold | theBear: fuck it, I'll sprunge them |
| hjf | R0b0t1: the revenue service is able to just go into your bank account and collect taxes |
| R0b0t1 | hjf: I mean in the US if I sold you something and scribbled down my name and a price it'd probably be acceptable as a legal document |
| FreezingCold | theBear: er I might not be able to sprunge half a meg.. |
| cheater | you know, given the amount of money the US jet set has, i'm surprised there isn't an enclave somewhere in south america where coke, lsd, and all the other vices are perfectly legal |
| evilbetty | just put it in the cloud |
| hjf | R0b0t1: if i deposit money into my own account, i pay a tax (0.16%) |
| hjf | R0b0t1: if i withdraw money from the same account I PAY THE SAME TAX AGAIN |
| theBear | FreezingCold, try one more time |
| theBear | dcc |
| hjf | R0b0t1: if i wire money betwen two accounts of mine. GUESS |
| evilbetty | thats in every country |
| bobo1on1 | a bank transfer tax? that is just ridiculous |
| theBear | heh nah, but it was closer to working, gimme a moment |
| evilbetty | if you have money you pay for it, if its not per transfer its in some other way |
| FreezingCold | theBear: let me just give you them via sprunge k? |
| hjf | bobo1on1: yes. |
| theBear | yeah k, i thought you said it was too big or something |
| evilbetty | i pay over 40% of taxes on my salary |
| hjf | bobo1on1: but it;s there. they put it in 2001 for the crisis, 'economic emergency law', |
| R0b0t1 | hjf: lol. |
| R0b0t1 | hjf: that's thoroughly insane |
| theBear | was gonna see if i can htaccess allow upload to my webserver, or just give yer a scp login |
| FreezingCold | theBear: curl -s http://sprunge.us/ARLR base64 -d xz -d > stocklogo.bin |
| bobo1on1 | sure, taxes on your salary, but taxes on moving money around is just evil |
| hjf | the government says we are better than ever.. |
| FreezingCold | theBear: md5sum is 187908e994f5b42710d13dbb5126d6d2 |
| hjf | but they keep pushing the economic emergency law 1 more year every time |
| evilbetty | its the same, i also pay for storing my money |
| cheater | hjf: where is that? |
| hjf | Argentina |
| bobo1on1 | I would move money around in single cent transfers just to fuck with them |
| theBear | curl, oldschool, surprised i still got it installed :) |
| evilbetty | then again ill kindly pass for south america:p |
| FreezingCold | bobo1on1: I do that a lot but not to fuck around with people :p |
| hjf | bobo1on1: its rounded to one cent |
| bobo1on1 | down or up |
| theBear | FreezingCold, looks good |
| hjf | up of fucking course |
| bobo1on1 | hehe |
| hjf | dude |
| hjf | the government is full of thieves |
| hjf | they are ahead you |
| FreezingCold | theBear: okay that's the stock logo for the moto g, let me send you the 'hacked' version with no unlocked bootloader |
| hjf | R0b0t1: you know whats worse? ANY country can do that. we just do it because we're worse. but the US has even more awful 'provisions' that would scare the shit out of you |
| hagbard | FreezingCold: It looks like the unlocked bootloader warning screen is put there by the bootloader itself. |
| bobo1on1 | we have high tax on inheritance |
| hjf | sounds like my government is crazy but the US just doesn't need to do it. but it very well could |
| hjf | bobo1on1: dude you have that bullshit corporate tax that keeps all your companies outside |
| evilbetty | why do you have to hide youur bootloader? |
| bobo1on1 | so you save money that already has taxes paid over it, then you die, taxes have to be paid again |
| hagbard | FreezingCold: Also, the moto g and the asus nexus 7 aren't really the same thing. |
| hjf | bobo1on1: yes but like this woman said: that's the government taking money over your dead body. who gives a fuck |
| R0b0t1 | hjf: Well, I'm aware of things that are like you describe in the US, but they're typically associated with high-volume business.. not a small business or two people interacting |
| shrdlu- | hjf, I heard that Argentina has realised it has vast shale gas reserves |
| R0b0t1 | weird |
| FreezingCold | hagbard: theBear can probably throw it up on a hex editor and see what's changed maybe? |
| hjf | shrdlu-: and we need 25 billion dollars to exploit them. would you lend us? |
| hagbard | FreezingCold: How would that help your Nexus 7? |
| theBear | i'll look into that if he doesn't get excited and solve it before i can focus good |
| hjf | shrdlu-: the government has 27 billion dollars in the central bank reserve. thats it |
| bobo1on1 | you could exploit a small bit, make money, exploit more |
| theBear | but i got some other basics to check first too, also grab a getprop export for me while we at it, on the nexus |
| bobo1on1 | standard business practice |
| hagbard | FreezingCold: I don't have either device, but they're not related. It's like looking at changes in a ford engine to fix a chevrolet one. |
| evilbetty | are you installing ubuntu mobile lol |
| hjf | R0b0t1: small businesses (like me) haev our own 'small taxpayer' thing. i pay a single tax that covers everything. $80/mo allows me to bill up to $20K/yr |
| shrdlu- | hjf, you need to get your ass down there with a pick axe and a siphon |
| hagbard | FreezingCold: I don't mean to dissuade you; but it doesn't seem to make a lot of sense. |
| theBear | hagbard, probably slightly related, pretty sure a bootloader can't print over the bootlogo from outside-os in android land, and very few companies bother to show unlocked outside of the bootloader/hboot/fastboot screens |
| theBear | and it don't gotta make sense to him, i just need a handful of hinty facts |
| hjf | shrdlu-: what for? we gave these to Chevron in a secret contract to perpetuity |
| shrdlu- | oh :( |
| hagbard | theBear: Fair enough. |
| shrdlu- | chevron are fucking evil |
| shrdlu- | is |
| evilbetty | and crazy |
| hjf | R0b0t1: i have a bank account in the US. since i'm not a citizen, the IRS takes 30% of all i make in interests there |
| evilbetty | you should have used swiss :p |
| hagbard | or bahamas |
| Loshki | hjf: no reciprocal tax relief agreement? |
| hjf | evilbetty: do the swiss allow you to open a bank account via email? :P |
| evilbetty | nah switserland is releasing many names these days to financial inspections of the countries pp are from |
| hjf | Loshki: i dont wnt my government knowing i have that |
| hjf | also guyd |
| hjf | guys |
| hjf | delaware |
| evilbetty | so no more switzerland |
| hjf | lol delaware |
| evilbetty | delaware sounds like a cookie factory |
| Loshki | hjf: hiding money from the government? They *love* that.. |
| theBear | 'well howdy pardner, we're in texas , yeehaw !' 'we're in .. delaware' |
| hjf | delaware is us' homegrown fiscal paradise |
| theBear | hehe, that early mike myers, genius |
| evilbetty | :o |
| theBear | kinda like that matrix dude before the matrix when he did cool movies |
| evilbetty | i never saw the matrix |
| evilbetty | i remember i turned the first one off because it bored me |
| theBear | but you SHOULD see 'so i married an axe murderer' ! and bill and teds bogus journey |
| hagbard | hjf: yes, lol delaware. delaware is very much one of the more ridiculous states in th eunion. |
| hjf | theBear: how about point break |
| hjf | i mean dude |
| hjf | i coul open a company in delaware myself |
| hjf | i think i should do that, just for shits and giggles |
| theBear | hjf, umm, i dunno, that's one of the ones that if i did see it, it was right in the peak of my drug and alcahol abuse, and at best i got hazy images of a hallway/living room |
| theBear | a shop that sells shits and giggles ? |
| evilbetty | lol |
| hjf | theBear: it's the one where he jumps off a plane and grabs the guy with the parachute mid-air |
| evilbetty | are those even comedies? |
| hjf | evilbetty: no..it's serious |
| evilbetty | meh |
| evilbetty | i only watch comedies |
| theBear | hjf, lots of movies done that now :) |
| theBear | evilbetty, good boy :) |
| hjf | i wonder what would happen if i ever request a US tourist visa and they find about my company in delaware |
| evilbetty | guantanamo |
| theBear | you'll be labelled a terrorist and sent to the bay |
| hjf | i refuse to go through the US visa process |
| hjf | i should get my italian passport |
| evilbetty | get one from a nonnoisy country :p norway or so, you'll be welcome everywhere :p |
| hjf | to get a us visa you need to prove you don't want to go live there |
| hjf | evilbetty: argentine passport is allowed everywhere except US, canada and australia |
| evilbetty | ok |
| hjf | 3 months in the EU, 6 months in the UK even |
| hjf | so anyway, i'll probably get my request denied if i try to get a us visa |
| evilbetty | who'd wanna stay here 3 months, or 6 months in uk :/ |
| hjf | cause like, i dont have a house, car, 'real job', wife |
| evilbetty | and us |
| hjf | i'm 31 and living with my parents. they will probably stamp my passport DENIED |
| hjf | you know how they give you a visa there? you have to leave your pasport at the US embassy |
| hjf | and 2-3 weeks later they will return it with the visa, that takes 1 full page of your passport |

| theBear | hi beaky ! |
| beaky | hello theBear |
| evilbetty | youtube comedy |
| evilbetty | usually with a video resolution to cry for |
| evilbetty | little fockers on tv |
| theBear | it's real comedy, cartoon network are just assholes so you only get little chunks on the tube |
| evilbetty | not my type of comedy, but i may as well leave it on |
| evilbetty | it got dark early very fast |
| evilbetty | im still stuck with the idea that if it gets dark its 22h |
| evilbetty | but its not even 21h yet |
| theBear | damn, you got the daylight savings or you living with polar bears ? |
| evilbetty | hehe i assume daylight savings will kick in soon |
| evilbetty | not sure |
| evilbetty | to save the day! |
| theBear | holy crap it gets dark late tehre |
| evilbetty | mcpixel saves the day |
| theBear | i like mc chris |
| evilbetty | mcpixel is cooler :p |
| evilbetty | he's a ginger that saves ppl by getting rid of the bomb |
| theBear | mc chris is a cartoon voice artist AND a novelty/joke famous mc |
| theBear | my buddy in teh other channel even met him ! |
| blockh34d | also, his backback has jets |
| evilbetty | ok |
| blockh34d | i heard he's hilarious |
| theBear | they've got the bomb ? |
| blockh34d | bought some weed from a friend once |
| blockh34d | immediately kicked him out of the dressing room after |
| blockh34d | 'ok now get out' |
| evilbetty | full of washing powder |
| theBear | lol |
| evilbetty | you have a dressing roomù? |
| theBear | doesn't everybody ? |
| blockh34d | he did |
| blockh34d | he's mc chris |
| evilbetty | isnt a dressing room a separate room with a mirror and racks of dresses? |
| blockh34d | i think normally that would be lame, getting ejected like that, but when mc Chris does it its funny |
| blockh34d | cause he's hilarious |
| evilbetty | is it really |
| evilbetty | i generally get annoyed by people that find themselves funny and act like it |
| evilbetty | eccept when its me ofc |
| blockh34d | sure |
| blockh34d | maybe its something about his voice |
| theBear | nah, he's a jester, awesome people find him funny, and he was gonna act like that anyway :) |
| blockh34d | its just really hard to take seriously |
| evilbetty | test |
| theBear | his voice is a big factor |
| evilbetty | everything froze except irc |
| theBear | if google hadn't effed youtube so hard i'd have a link by now |
| blockh34d | theBear: yah, its right in line with the ATHF sort of humor |
| evilbetty | pfft |
| evilbetty | i need an arduino |
| theBear | pretty sure he was in athf, shake maybe, he plays the dude that is inside shake in one of the post modernist bits |
| evilbetty | i need to decode some IR but dont feel like writing my own code |
| blockh34d | theBear: Yeah i think he's one of the moonites? something like that |
| theBear | pffft, you need lirc or a real avr and the stock rc5 lib from avr-c |
| theBear | hmmm, i can see him being grrr (the little one) |
| evilbetty | that would be nice but its not rc5 :pp |
| blockh34d | errr |
| theBear | i been getting scary good at picking cartoon voices recently |
| blockh34d | Mitnicknock and ERRR |
| theBear | evilbetty, what then, sony protocol '? |
| blockh34d | They are from THE MOON |
| evilbetty | samsung & nec |
| theBear | ignignot |
| evilbetty | samsung is same as nec with a different startpulse tho |
| theBear | their vertical leap is beyond all comprehension ! |
| blockh34d | theBear: oh thanks i can never remember how to spell his name |
| blockh34d | hahaha |
| theBear | https://www.youtube.com/watch?v=h7c97JnBhbM selection of mc chris parts in sealab |
| theBear | i dunno if that's how you spell it, but that's how you say it |
| blockh34d | Jazz Cola, best episode |
| shrdlu- | joan rivers died |
| blockh34d | of sealab |
| theBear | shrdlu-, holy crap ! i saw her and her daughter on tv just last night |
| evilbetty | ok ill click it |
| blockh34d | aww, she was fun i'll miss her |
| evilbetty | but i really hope its worth it |
| blockh34d | such a funny sense of humor |
| cheater | that's a human being? |
| evilbetty | bleh |
| theBear | blockh34d, i'm quite fond of the mouse-head robots and legend of baggypants (monster hesh/golf) |
| blockh34d | oh i dont know the first one but the second is a classic you're right |
| evilbetty | no audio, and without sound i dont wanna be watching cartoons about male cheerleaders :p |
| blockh34d | i think jazzcolor was the first time most people heard the bobafette song |
| blockh34d | jazzcola i mean |
| theBear | no audio ? wtf ? adultswim effing you or just google effing the tube ? |
| evilbetty | are you prepared to be the gothfocker? the goatfucker? the gothfocker. |
| evilbetty | no audio cable plugged into pc |
| theBear | oh, work, yeah heh |

| cheater | 0001ACTION puts evilbetty's arm in a blender0001 |
| cheater | did that for you |
| blockh34d | UPGREYDD |
| evilbetty | i have a titanium arm |
| blockh34d | does it blend? |
| evilbetty | no |
| blockh34d | that doesnt sound right |
| evilbetty | well |
| blockh34d | pretty sure everything but Chuck Norris blends |
| evilbetty | it doesnt get blended |
| evilbetty | it sure blends |
| cheater | bored |
| blockh34d | k |
| cheater | booooreeeed |
| evilbetty | then make me some code |
| theBear | ooh titanium chameleon, all blending with stuff |
| evilbetty | samsung ir decoding code |
| theBear | samsung ? they use rc5 |
| evilbetty | they dont |
| theBear | the two in the next room do, or rc something at least |
| evilbetty | they use nec with a different startpulse like i said 5 min ago |
| theBear | well i didn't listen then |
| evilbetty | i noticed |
| theBear | ! |
| theBear | why don't you tell me what you really think |
| evilbetty | because im trying to be polite today :p |
| theBear | 0001ACTION imagines betty going mental on the other side of the world0001 |
| theBear | aww, i'm not, but i was nice to begin with <grin> |
| evilbetty | lol |
| evilbetty | Step 5: Your C-Based Project Should Be On C: Drive |
| theBear | damn i gotta learn to stash alachol like the alcaholics in movies.. i'm all sober, that's the problem today |
| blockh34d | theBear: check the toilet tank |
| blockh34d | also in the overhead lights |
| theBear | blockh34d, i always thought that was the best one in movies, but only ever did it myself at old old work |
| theBear | i had my own office and ensuite toilet :) |
| blockh34d | i keep wishing someone would use a prosthetic arm as like, a kegerator or something |
| Loshki | Between the sofa cushions. In the filing cabinet. Under the vacuum cleaner (safest place in our house. It'll *never* be discovered). |
| blockh34d | little arm shaped flask |
| evilbetty | lol |
| theBear | now that's what my walkin' stick needs, a flask ! i'd use that WAY more than a silly sword |
| blockh34d | for sure |
| evilbetty | an arm shaped flask reminds me of this http://img.photobucket.com/albums/v493/scubastza/Blog%20Stuff/funky.jpg |
| Loshki | Little British Joke: Q) where do the French hide their money? A) under the soap |
| evilbetty | not very safe for sork |
| evilbetty | not very unsafe either |
| bobo1on1 | theBear: get a hollow walking stick |
| bobo1on1 | which you can drink out of |
| theBear | in schwarzennegers action blockbuster 'red heat' there's a dude with a pegleg full of coke, till arnie tears it off and smashes it on the floor of the cafe they in |
| theBear | Loshki, lol |
| blockh34d | evilbetty: hahah what a funky kids bracelet! |
| blockh34d | can you imagine the poor kid that gets that as a gift and decides to wear it to school |
| theBear | bobo1on1, it's already hollow ! and well, obviously that you can drink out of, that's what flask are for |
| evilbetty | her son didnt wear it much :p |
| blockh34d | 'back to school gift' |
| evilbetty | lol |
| hjf | joan rivers died |
| hjf | omg |
| theBear | why people keep saying that ? |
| evilbetty | who |
| hjf | how am i going to laugh at the red carpet now |
| hjf | evilbetty: that evil bitch who laughed at celebrities clothes |
| theBear | lol @ bracelet |
| blockh34d | hjf: i dunno, she's irreplacable |
| evilbetty | didnt she do some soap? |
| blockh34d | maybe betty white can step in for a while |
| theBear | i dunno, that voice was gold, and she acted increasingly in her later years |
| bobo1on1 | so apparently there is an ongoing investigation how it could happen that joan rivers got cardiac arrest during surgert |
| blockh34d | carry the torch of hilarious old gals on the red carpet |
| theBear | betty white doesn't sound like a jewish zombie at all ! |
| bobo1on1 | well, maybe it's because she's fucking 81 years old |
| blockh34d | she could |
| blockh34d | betty white has a lot of range |
| blockh34d | and can drop an f-bomb like no other |
| evilbetty | anyuway with craigs you never know if its a joke or not i guess |
| ShadowJK | They put a tube down her nose and it accidentally dislodged coke |
| theBear | i'm barely over a 3rd of that age and i had to sign something that said i understand that can happen during an operation, everyone knows that |
| blockh34d | i blame that icebucket challenge |
| theBear | i miss the golden girls |
| blockh34d | no real rational reason why |
| blockh34d | i just hate that shit |
| blockh34d | she did the icebucket thing a week beforehand |
| evilbetty | whats the name of that long running soap again |
| evilbetty | bold and beautiful woop |
| theBear | miz doob-wah and the ever lovely bea |
| theBear | ShadowJK, heh |
| blockh34d | yah, such a mold-breaker of a show |
| Loshki | I am not to be revived unless I can do an hour of stand-up. -- Joan Rivers |
| theBear | hmm, friend of mums did that icebucket thing on the weekend at work, wonder if he's dead too |
| evilbetty | wow |
| blockh34d | previously i think people just assumed that when actresses hit 40 they get recycled or launched into the sun or something |
| evilbetty | 2014 must be the year of the new tv programs |
| theBear | blockh34d, err, previously they did :) |
| evilbetty | i never saw so many new tv programs at once after summer |
| evilbetty | i even saw some funny things :p |
| Loshki | It's like the Japanese soft drink approach to TV shows.. |
| theBear | i don't mind this cougartown show |
| blockh34d | well thank-the-spaghetti-monster for the golden girls then, cause older ladies crack me up with their comedy, I guess cause you expect them to be all prim and polite |
| blockh34d | whats her name from grandmas boy |
| blockh34d | grandmas boy kinda reminds me of golden girls |
| theBear | grandmas boy ? |
| blockh34d | oh hell ya |
| blockh34d | you gotta watch that shit |
| evilbetty | lol |
| blockh34d | like 3 times on repeat at least |
| blockh34d | catch up with the rest of the world |
| theBear | i don't wanna catch up with them, but i'll watch this |
| blockh34d | you could never catch up with me at watching grandmas boy |
| blockh34d | i have the high score |
| blockh34d | love that movie |
| evilbetty | lol geeks |
| theBear | yeah, well err, it's quite possible i know every sealab and aqua teen episode word for word, including the aqua something you know season and the un-beeped version of the fcc rant about tattooing a gorilla in guatamala |
| evilbetty | trying to beat eachother in watching the same movie the most |
| drac_boy | hi |
| theBear | pfft, i never watched it, and i won in the cartoon watching category for 500 points, what is awesome ? i ain't no geek, yo |
| evilbetty | normal nongeek ppl saw police academy the most |
| blockh34d | theBear: nice. I actually build an e-helmet |
| evilbetty | lol |
| blockh34d | eDork is my fav ATHF |
| blockh34d | also Super Model |
| theBear | i saw all 3 police academies a lot in the 80s, but since then cartoons came into their element |
| evilbetty | all 3? |
| Sendoushi | hey guys. help me here. for guitar pedals which NPN transistor would you use? Something easy for a noob to use |
| theBear | blockh34d, heh, can you text message and express your electronic emotions via your forehead ? |
| Loshki | I've seen every doctor who episode ever. Started when I was 5 years old.. |
| evilbetty | never saw dr who |
| theBear | Sendoushi, whatever is lying around without more info, you know, bc3 or bc5 something maybe, ?n2222 maybe |
| blockh34d | theBear: Yes I can, in a variety of fonts. Also, it has a power antenna |
| Sendoushi | hmm ok then |
| Loshki | evilbetty: you need to fix that.. |
| Sendoushi | so i'll buy just the cheapest |
| theBear | i been missing monkey magic recently, and do i remember seeing an ad for the musical vesion recently ? |
| drac_boy | just wondering but any light suggestions on a nice audio codec for mobile purpose? (onboard speaker/mic, external line-out source, and one digital output source as well) |
| theBear | blockh34d, awesome ! |
| drac_boy | apparently the intel HDA needs an external codec so |
| theBear | drac_boy, probly anything you see in pcs or lappies |
| evilbetty | metal 2n2222a ones :p |
| theBear | hda is actually more of a protocol/bus standard than an actual 'card' |
| drac_boy | thebear mm so realtek? |
| blockh34d | theBear: i'm just kidding it does neither of those things but it is incredibly dorky looking |
| theBear | most of them made up of 2 or 3 chips |
| theBear | drac_boy, or crystal |
| drac_boy | thebear..thats what I was starting to suspect when I saw it mentioning for external codec |
| Loshki | evilbetty: try the episode called 'blink'. It's fairly standalone. You'll know after that if you want to see more.. |
| blockh34d | theBear: http://s13.postimg.org/kvykdw2dz/IMG_2521.jpg |
| drac_boy | crystal? didn't know that still existed hmm..ty going look up now :-> |
| evilbetty | you forgot the tinfoil head part |
| theBear | http://www.carmi.se/misterstarshine/img/conv_1.jpg here's one boo made earlier |
| evilbetty | is that an old or new dr who? |
| theBear | blockh34d, hehehe, i like it |
| blockh34d | if i ever make a housing its going to have an uncanny resemblence to the eHelmet |
| theBear | blockh34d, does it have nightrider lights where the filter used to go ? |
| blockh34d | and i really will put a motorized useless antenna on it |
| blockh34d | it should |
| evilbetty | what does uncanny mean? |
| blockh34d | i will put that on the list of upgrades |
| evilbetty | i read this a lot lately |
| evilbetty | also with comics |
| blockh34d | it means xmen is awesome |
| blockh34d | actually means 'unnaturally awesome' |
| evilbetty | right |
| theBear | uncanny, like umm, unsettlinglym aybe |
| evilbetty | wat :p |
| blockh34d | seems to normally have a positive tone |
| theBear | like, err, amazingly maybe |
| blockh34d | like 'that is freakish but cool' |
| theBear | it's commonly used as a measure of how much two things are alike |
| evilbetty | its it invented in a comic or so? :p |
| blockh34d | it was part of the title of the Xmen comic |
| theBear | no, it's a real word :) |
| theBear | oh, the uncanny xmen |
| blockh34d | for a while, maybe still is. The Uncanny X-Men |
| theBear | heh, old school, back when dragonball hadn't yet grown a z |
| evilbetty | thats a long time ago |
| evilbetty | already as a small kid dbz irritated me on tv |
| blockh34d | for a while I owned the first 12 xmen |
| blockh34d | comics |
| theBear | me too, i liked very few cartoons until i grew up and learned to appreciate them |
| blockh34d | not the actual xmen |
| evilbetty | the ones not worth much? :p |
| theBear | uncanny (German: Das Unheimliche, 'the opposite of what is familiar') that's a good one |
| blockh34d | evilbetty: no they were pretty pricey. Got a good deal at a comic show once |
| theBear | http://en.wikipedia.org/wiki/Uncanny |
| evilbetty | i have the first duffman comic :p |
| theBear | wow, no wonder it's so hard to define, it's a complex meaning |
| theBear | herm, heimliche is familiar ? |
| evilbetty | and a graph with a moustache |
| theBear | http://en.wikipedia.org/wiki/Uncanny#mediaviewer/File:Mori_Uncanny_Valley.svg yeah, that's gold ! |
| theBear | everything is improved with a moustache |
| evilbetty | lol |
| drac_boy | mm Cirrus..been a long time I ever heard that name |
| drac_boy | what was that last time I ever saw cirrus.oh yeah an old vga agp card that only had 2D capacity alone yet |
| theBear | i suspect you mean pci, and yeah, they oldschool, i got one right here, think i had one in the xt days too |
| evilbetty | agp is not old :p |
| theBear | definately 286 days |
| blockh34d | Engage TURBO Mode |
| evilbetty | i had a trident with 512kB ram:p it kicked ass :p |
| evilbetty | trident 9000 or so |
| blockh34d | i think i had one of those too actually |
| drac_boy | thebear.actually it was agp..you had to wonder how many 2D-only cards ended up in the early agp era |
| blockh34d | back in 3d studio R4 days |
| ikarus | Trident 8900 ISA |
| theBear | drac_boy, not many, most of the companies that made them had already died |
| ikarus | I still own that one |
| evilbetty | 16bit isa |
| ikarus | drac_boy: AGP ? i740 Intel was 2D only |
| theBear | consider there were LOTS of pci and isa 3d accell overlay cards, but i can't think of a single agp one |
| drac_boy | thebear.yeah..and beside agp bandwidth was kinda wasted on not having 3D included too |
| theBear | mmm, to an extent, things like full def dvds and hd stuff killed a pci in a hurry |
| evilbetty | i assume you can control your own isa vga card with an mcu |
| drac_boy | thebear thats a very tiny group of users tho |
| theBear | mmmm, this grandmas boy movie looks good in the gimage machine |
| blockh34d | theBear: it really is a classic |
| drac_boy | pci replaced isa rather easily only because there was actually plenty of everyday things that could easily choke on even the best 16bit isa buses |
| theBear | meh, my voodoo 2 and tseng 4000 are classics |
| evilbetty | back in the days you had another slot for videocards |
| evilbetty | forgot the name |
| drac_boy | evilbetty likely it was just the same slots but maybe with a dedicated bus |
| blockh34d | i only remember PCI and then AGP and then PCI-Express |
| blockh34d | there was another? |
| evilbetty | isa and something |
| drac_boy | mind you there was one pci oddity that I do recall of.. the B&W G3 may had several pci slots but you always explictly put your pci video card in the first slot as it was 'paired' for high bandwidth . the other slots got lower priority |
| theBear | herm, way back you mighta had a vesa-local (vl) bus, that was like a pci extra-slot in front of 16bit isa slots |
| drac_boy | thebear.I believe that was generally stuffed with storage controller cards for most part |
| drac_boy | just like pci-x never saw much of any non-storage useage either |
| Rab | http://en.wikipedia.org/wiki/File:KL_ATI_Mach_64_VLB.jpg |
| theBear | maybe, i couldn't afford storage controllers back then, but i did eventually get a video card for it |
| theBear | that was way before pci |
| drac_boy | but anyway thebear..I think my point was..audio, tv tuner, most data streams, etc all still can be done within the pci bus .. so it still has quite plenty of uses |
| evilbetty | maybe it was just e-isa |
| drac_boy | compared to isa which late on was easy to choke out |
| theBear | wow, that musta been an early mach64 |
| theBear | evilbetty, vl bus, like that last link |
| evilbetty | its one of them anyway |
| theBear | mmmm, pci gets real tight with even a single full pal def and framerate video running in realtime uncrompressed, need all kindsa tuning and a decent hw buffer on yer capture to not bottleneck and choke regularly |
| evilbetty | vl or eisa |
| drac_boy | oh and if anyone's wondering.its official.. Ricoh doesn't even sell any card controllers anymore . only Ti still has relative products for expresscard/cardbus controllers |
| theBear | hmm, isn't eisa just 16bit isa |
| drac_boy | thebear..umm.I dunno what you're talking about because a 720p tv source and 1394a card could coexist on same bus and never shoot each others down |
| theBear | heh, i ain't used a laptop card since before ricoh was into the business :) |
| evilbetty | http://i.stack.imgur.com/ualb8.jpg :p |
| Rab | theBear, EISA was 32 bit. |
| theBear | drac_boy, try it while that bus shares with storage and north/south bridge and even a tiny base load and talk to me again, and remember raw is MUCH bigger than dtv data streams if that what you thinking about |
| drac_boy | rab whatever happened to eide? (not same thing I know but the mention of the 'E' letter had me wondering) |
| evilbetty | anyway its not that important |
| Rab | Weird stuff: http://en.wikipedia.org/wiki/File:KL_ELSA_Winner_1000_ISA_EISA.jpg |
| theBear | Rab, damn, i forgot a slot :( |
| theBear | drac_boy, everything started supporting the additions and it just got called ide again |
| evilbetty | SLI! |
| theBear | hehe, upside down upside down mr squiggle |
| drac_boy | thebear..you're thinking that a bridge somehow can know what a *400mhz* ram is yet not know what pci slots are..try again? |
| theBear | ooooh, sip ram modules |
| drac_boy | ;) |
| evilbetty | oh lol i didnt see the other connector |
| theBear | drac_boy, what ? |
| evilbetty | are you sure they're ram |
| evilbetty | i assulmed they were resistor arrays where you dont put ram |
| theBear | evilbetty, yep, graphics card, that age, sip, ram |
| drac_boy | heh evilbetty |
| evilbetty | ok |
| theBear | very rare |
| evilbetty | and worth nothing! |
| evilbetty | 0001ACTION removes his ! key0001 |
| dhrosa | hmm, how to cut through steel cable |
| dhrosa | the thin shit used on bike shifters |
| evilbetty | with my included key remover tool :p |
| evilbetty | waterjet |
| theBear | and i'm saying that 33mhz bus with variable latencies and associated overhead % changes, and absolutes like storage governor timeouts and deadlines, that pci is tight for a lot of stuff |
| drac_boy | just curious but does 'stereo aid mono line-level' mean anything specific? |
| theBear | dhrosa, depends what ya got, i tend to use my mini-boltcutters recently |
| evilbetty | it sounds chinese |
| theBear | sounds kinda hearing loop related |
| Rab | I heard PCI was technically pretty crappy. As in, max length was four slots before signal reflections started causing problems..if you saw a MB with more than four slots it had two PCI controllers. |
| drac_boy | well thats what it says near bottom http://www.cirrus.com/en/products/cs4202.html |
| Rab | And that's why moving cards to different slots sometimes helped. |
| theBear | Rab, the 2 controllers for over 4 slots isn't strictly true, but all that makes sense |
| drac_boy | rab actually two controllers would perhaps be because of it being a high-bandwidth board where someone actually was running several highend cards at once |
| drac_boy | but most cheap atx boards did with just one because very few users ever really were bothering |
| drac_boy | mind you some tyan boards did have three due to the heavy uses of scsi-raid cards etc |
| theBear | especially early on, and depending on bios and os even today (in my world) juggling slots for all kinds of enumeration and pnp-style-assignments like irqs makes sense often |
| evilbetty | lol |
| synx508 | horrible memories of hard-wired IRQs that shared with things that weren't compatible |
| evilbetty | with a circus music |
| theBear | the old alpha boxes had all kinds of bridges, pci and other weird fairly specific/proprietry kinda interfaces |
| evilbetty | ratataratarara tarata |
| Rab | I think PCI might have relied on reflections for timing, but I don't know much about it. |
| drac_boy | (then again Ultra 320 Raid was exactly why tyan had 2-3 slots per full controller cards) |
| theBear | meh, pci is still a fairly basic/traditional bus, 33mhz standard, 32 datalines on normal, decent address space, discrete (yet shared) irq lines |
| FreezingCold | fuck yeah I passed my entrance exam |
| Rab | synx508, I was just thinking about that the other day. Sound cards and IDE controllers with a million unmarked jumpers to choose address/IRQ..better not lose one! |
| drac_boy | but home users..well..heck the Promise TX133 cards barely even used half of the given bus width at all |
| theBear | hooray ! are you inside now ? |
| hagbard | uhh, most enterprise motherboards had multiple PCI busses anyways. |
| theBear | that's cos the promise cards were slow :) |
| drac_boy | thebear.not really.it was the hds that were the limit |
| theBear | drac_boy, oh yeah, how quickly we forget :) |
| drac_boy | it explains why even although ATA133 existed most hds still were only marked as ATA100 |
| evilbetty | promise woop, that was the brand i was thinking of a few days ago but couldnt remember |
| drac_boy | and anyway thebear did you see that cirrus link above? |
| hagbard | drac_boy: we had an Intel E7500 based board - actually, it's in my basement - every 2 PCI or PCI-X slots were on a seperate bus. |
| theBear | they were starting to get into on-hd 'big' buffers at that stage too, no command queing in ata but still the extra cable speed didn't hurt, also often sharing a single ide bus between two devices |
| theBear | umm nup |
| drac_boy | evilbetty Promise still makes budgetary controller cards to today .. if you just wanted lazy JBOD expansion then that was who you bought |
| drac_boy | but for real raid..adaptec/etc are better off |
| evilbetty | i was treing to remember the raid controller on my p4 |
| synx508 | I was using SCSI-UW (or was it UW2?) when those promise cards came out. They were so pathetic. |
| theBear | i still got a couple dac960 scsi2 raid cards soemwhre, they were AWESOME |
| theBear | drac_boy, heh it totally does. i suspect that means mono headphone output |
| drac_boy | synx.heh.scsi was more toward Adaptec . I can't recall of anyone else that even did it well at all :-> |
| Shawn286 | Howdt |
| evilbetty | i got a hw raid card with ultra scsi here too somewhere, and 2 15k disks |
| Shawn286 | *Howdy :D |
| evilbetty | but i dont use it |
| evilbetty | its in a dell server thats just qstanding against the wall |
| drac_boy | thebear.ty anyway, if '6-channel playback' means analog audio then I think I probably like that codec chip |
| synx508 | I had a 4G IBM disk, which ran hotter than anything I've used since |
| Shawn286 | fixed a couple bad solder connections, and replaced a power cable in my laptop's ac adapter :D |
| synx508 | I gave it a dedicated 120mm fan |
| Shawn286 | no more laptop shutoffs when I move the ac adapter |
| theBear | drac_boy, can't think what else it could mean, and it matches similar spec pc output specs |
| hagbard | Oh, god, HW raid adapters were so slow back then. i960 based crap |
| theBear | erg, stretching can do no more, i gonna watch a movie |
| Shawn286 | anyone here familiar with DipTrace? |
| theBear | hagbard, other people probly had post 4gb sized scsi drives, but those 960 things kicked ass on big arrays of shitty old disks |
| drac_boy | hagbard mind you I kinda skipped x86 computers on and off back then . still somewhat doing it to today :-> |
| synx508 | i960 was developed for something else entirely wasn't it? RADAR or something? |
| hagbard | theBear: yeah |
| hagbard | theBear: Fair enough |
| theBear | seacrest out |
| drac_boy | wonder how old the adaptec 6405E card must be anyway |
| hagbard | I suppose an i960 doesn't suck so bad compared to a TI SuperSparc @ 35MHz. :) |
| theBear | my adaptec 29?? and err, 27?? are pretty old |
| hagbard | synx508: Maybe the i860? It was supposed to be the fpu monster. |
| hagbard | theBear: 2940 |
| theBear | hot damn it took a long time to build glibc and gcc on a supersparc, even with dual 60mhz procs |
| evilbetty | i960, wasnt that one in the xray machine teardown on mikeselec |
| hagbard | theBear: or 2940UW, 2940U2W, then it went 29160/39160, 29320/39320. |
| theBear | yeah, 2940 |
| theBear | the other one was older, similar setup but scsi1/10mb max |
| synx508 | I had a 2940U2W, then a 39160 I believe |
| hagbard | I remember reading mailing lists, knowing nothing, and insisting on a Symbios or buslogic scsi card, 'Because that's what Linus used.' |
| theBear | i still use the 2940 if i ever use the scanner |
| hagbard | synx508: the 39160 was dual bus, and 64bit pci-x |
| theBear | anyway, gotta recline, for health, l8r |
| hagbard | theBear: take it easy. |
| theBear | you can rely on that ;-) |
| hagbard | synx508: The frustrating thing of the 39160/39320 were vhdci connectors. |
| hagbard | theBear: watch the jason scott presentations! |
| hagbard | theBear: I'll get you the youtube link. |
| drac_boy | mm sorry to ask but any thought on what 'single-ended output' could mean on an audio chip? |
| hagbard | theBear: https://www.youtube.com/watch?v=KSWqx8goqSY&index=1&list=PLx_a2qpaf00U7gVa38PvvsquRNFZ9zOvT |
| dhrosa | drac_boy: as opposed to differential |
| hagbard | drac_boy: not differential |
| hagbard | drac_boy: Like proaudio XLR's |
| drac_boy | sorry but I'm a bit naive to certain audio things .. whats non-differential audio? or is that just another term for unbalanced? |
| hagbard | unbalanced, yes. |
| drac_boy | ahhh.think I get it now ty hagbard |
| synx508 | oh, this card seems to be a LSI Logic 213230, whatever that is. It's 64 bit but single bus. Pretty sure I have a 39160 somewhere |
| hagbard | drac_boy: it's like SE/LVD scsi |
| hagbard | synx508: IMHO, the LSI was a better adapter. |
| drac_boy | hagbard I had to ask because a smaller Cirrus chip basically is Serial Input on the host side and Single-Ended on the audio source side . but its making sense now tho |
| drac_boy | again ty :) |
| drac_boy | 0001ACTION will have to see if the Intel HDA is indeed some sort of serial bus as to go with this little codec chip0001 |
| hagbard | drac_boy: Yes, but it's not as easy to use as AC97 |
| drac_boy | hagbard since you mentioned it now - I had to mention: isn't it funny how a lot of people always called scuzzy a 'black magic' or 'voodoo' only because they are having a bad day trying to get anything to work? :P |
| drac_boy | me I've never had any problem with various types of scsi setups..maybe I just knew what I was doing or simply got lucky all the times :p |
| hagbard | drac_boy: Because they didn't read the manual and learn how to terminate their bus properly? |
| drac_boy | heh? |
| hagbard | The same deal with IDE and CSEL/Cable Select |
| drac_boy | 0001ACTION throws a very thick RTFM bible at the direction of hagbard's head0001 |
| drac_boy | like that? ^^^ |
| hagbard | People didn't bother to learn how it worked to use it properly - wihch is insane, because it's incredibly straightforward. |
| hagbard | drac_boy: I didn't have problems either - but I would read the manual. |
| drac_boy | Cable Select..wasn't that the one where the ide ribbon was traced out in a certain way that channel 0 was always going to be master and channel 1 was slave? |
| hagbard | drac_boy: I mean, I had trouble finding a 3944 - the HVD version of the 3940 and an HVD terminator to run an old DLT tape drive. |
| hagbard | drac_boy: Yes, basically. |
| drac_boy | I've never ever came across such ribbons myself but I've heard about it nevertheless |
| hagbard | drac_boy: you have. |
| hagbard | drac_boy: In fact, I bet you that every single IDE cable you have works that way. |
| shrdlu- | * GentileBen is now known as SirCrispinTheJew |
| hagbard | drac_boy: there was rarely a visible cut in the cable. |
| drac_boy | I generally only had 1-2 ide drives per system at the time anyway (so it was either cdrom on primary master or hd on primary master and cdrom on secondary master) |
| hagbard | drac_boy: Sure, I don't mind. |
| drac_boy | did sometimes use single-channel ribbons tho |
| drac_boy | (oddly enough it was dell systems salvaging that provided most of them) |
| hagbard | sure, super-shorty's. |
| synx508 | I've got one of those nice 3ware IDE RAIDs in a box here. It was the only decent IDE RAID |
| hagbard | Also could get stupidly long ones out of Macs |
| hagbard | synx508: Yeah, agreed. |
| drac_boy | hagbard well I liked them better because I -never- had any kind of slave drives anyway (any extra hds was always off the pci scsi card anyhow) |
| hagbard | Sure. |
| drac_boy | say hagbard I'm just asking but what sort of drives do you like to buy these days whether for yourself and/or for others you're helping out? |
| drac_boy | and as for that 'not as easy as AC97' remark earlier on.well..I don't mind it if it means a smaller footprint seeing I don't need much fancy audiowork |
| drac_boy | but yeah if it was going take another hour to program.I'll probably skip it for sure |
| hagbard | drac_boy: Drives for anything in particular? |
| drac_boy | yeah |
| hagbard | drac_boy: Generally, SSDs. Samsung or Intel SSDs. |
| FreezingCold | so stupid question incoming. |
| FreezingCold | Can I use three 3.3V voltage regulators together to get 9.9V? |
| hagbard | drac_boy: For 3.5' drives, basically bigass SATAs. I still have some machines at work with 12 or 48 4TB drives. |
| hagbard | drac_boy: I loathe optical drives. |
| FreezingCold | I don't even have an optical drive |
| hagbard | drac_boy: I haven't been able to muster the courage to throw away my tape drive collection. |
| SpeedEvil | I have a decent optical drive. It can do 0.4G for three months. |
| hagbard | drac_boy: https://dl.dropboxusercontent.com/u/99642288/2014-03-20%2013.47.34.jpg |
| drac_boy | hagbard mm.for me its generally seagate constellation on most systems with exception of some old samsung hds for any laptops needing replacement drives |
| DusteD | I was disappointed when I looked for new motherboards, there's no god-damn floppy controllers on them any more! |
| hagbard | drac_boy: The SAS or SATA variants of the constellations? |
| drac_boy | and system with no optical drive = either it gets one or its going into the for-scrapper junk bin . sorry but thats just the way it is around here ^_^ |
| drac_boy | dusted heh :) |
| drac_boy | dusted why do you still need disk drives btw |
| soil-d | or even worse trying a sata dvd-rom with a windows for it to tell you afther loading to put in dvd-rom drivers |
| drac_boy | hagbard sas variant |
| soil-d | :P |
| hagbard | drac_boy: Yeah, I don't think they're worth the expense unless they're in a dual-controller storage array |
| hagbard | and those storage arrays have not served us well. |
| drac_boy | hagbard mm I dunno but its always been one card with 2 hds here (although a while ago I finally offered the option for four hds instead but not surprisingly very few people are picking that) |
| drac_boy | to our own I guess |
| hagbard | drac_boy: Were you aware that the purpose for SAS on nearline disks is for when they're attached to multiple controllers simultaneously? |
| hagbard | Like, storage arrays with failover backup controllers |
| drac_boy | I don't use nearline so dunno about that ^ |
| hagbard | I thought you said you used constellation drives, my bad. |
| drac_boy | its pure sas |
| hagbard | Yeah. |
| drac_boy | might be the other series do have nearline but I wouldn't know |
| hagbard | No, constellation drives are nearline. Wether they have sata or sas, they're still nearline. |
| hagbard | The point was simply, if you're using them in regular machines or servers, you can use the singleported sata variant instead of paying for premium sas when you can't even use the second port. |
| hagbard | The controller on the drive, actually, is the same chip. |
| drac_boy | anyway hagbard about audio again heh.this is what I had been looking at http://www.cirrus.com/en/products/cs4270.html |
| hagbard | which is what amuses me. |
| drac_boy | still have to check if PCM is on the intel side |
| hagbard | drac_boy: hrm. not sure if I follwo 'PCM is on the intel side?' |
| drac_boy | heh sorry..I meant that I still had to check if the 'intel hda' thing had a matching pcm bus for to go with that codec |
| hagbard | drac_boy: yeah.. quite different busses. |
| hagbard | drac_boy: Basically, the intel hda bus is considerably more complicated. |
| hagbard | drac_boy: http://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/high-definition-audio-specification.pdf |
| anonnumberanon | I can't seem to get the current density vector J from this magnetic field intensity vector H(x,y): y^2 ax -x^2 ay |
| anonnumberanon | I find 0 for the vector J |
| anonnumberanon | I took the curl of H and I get 0 |
| anonnumberanon | can anyone help? |
| anonnumberanon | am I right? |
| dhrosa | hmm, let's see |
| dhrosa | to the wolfram |
| anonnumberanon | because after that I need to integrate that vector but if it is 0 then the integration will not be interesting at all.. |
| dhrosa | you don't integrate the curl |
| anonnumberanon | no i didn't say that |
| dhrosa | oh |
| anonnumberanon | i said i took the curl of H to get J |
| dhrosa | sorry |
| anonnumberanon | and then I integrate J in order to get the circulation of H around a loop of wire |
| mbwe | hi everybody i am looking for simple linux software to do electronic network drawing, i tried dia, but don't like how its working, any idea's? |
| jeremyabel | kicad |
| jeremyabel | is pretty much the defacto linux electronic design software, at least open-source-wise |
| theorbtwo | Not so open source wise, cadsoft eagle. |
| jeremyabel | yeah, they have a free hobbiest version |
| jeremyabel | uncommercial hobbiest, that is |
| jeremyabel | I use the paid hobbiest version, personally |
| blocky | how capable is ngspice? |
| blocky | is it pro quality? |
| FLHerne | mbwe: There's Qucs, but it's a bit unfinished still I think |
| jeremyabel | is Flixel on linux? |
| jeremyabel | I can't remember |
| mbwe | jeremyabel: theorbtwo i am talking about this kind of drawings http://upload.wikimedia.org/wikipedia/commons/thumb/b/b4/Ohm%27s_Law_with_Voltage_source_TeX.svg/220px-Ohm%27s_Law_with_Voltage_source_TeX.svg.png i thought that kicad was more for pcb disign etc, its not i want to simulate something only make drawings of the teachers example |
| jeremyabel | yeah |
| jeremyabel | kicad does schematics too |
| jeremyabel | you need a schematic before doing a board layout |
| mbwe | true, jeremyabel :) |
| jeremyabel | I'm not sure what they use to make for teachers examples though |
| jeremyabel | like with the nice fonts and lines and all |
| mbwe | dunno, somebody sugested to use an svg program like inkscape to that kind of drawings |
| jeremyabel | yeah you could if you wanted total control |
| jeremyabel | find some library of symbols you could use |
| jeremyabel | depends on the visual fidelity you want |
| jeremyabel | like if you want it too look pro and like textbook stuff, I have no idea what they use for that |
| jeremyabel | I wonder if there's a font for those symbols anywhere |
| analognoise | Its probably done with Circuitikz |
| jeremyabel | ahhh yes that looks like it |
| analognoise | ..which is a huge fucking pain in the ass. |
| jeremyabel | http://www.texample.net/tikz/examples/tag/circuitikz/ |
| jeremyabel | aw |
| jeremyabel | good god |
| jeremyabel | http://www.texample.net/media/tikz/examples/TEX/mosfet.tex |
| jeremyabel | LaTeX for circuits.. |
| analognoise | If you want post script high quality outputs, try xcircuit |
| analognoise | At some point you probably actually want to do the circuits part, rather than spend more time fucking with latex. |
| mbwe | oke cool, let me have a look |
| analognoise | just my 2c |
| Shawn286 | is the pcb channel dead? |
| jeremyabel | there's a pcb channel? |
| ahmadexp | emitter coupled logic is the best |
| beaky | i like analog logic |
| beaky | infinite states, infinite ways things can go wrong |
| beaky | with digital, sure its finite states, but combinatorial ways things can go wrong |
| enthd | how do you encode a signal |
| enthd | er |
| enthd | I have a set of N symbols which I need to be able to make distinct within some radius in C |
| enthd | how do I represent each symbol? |
| dhrosa | radius? |
| enthd | e.g. if I had 4 total symbols I could use QPSK |
| SpeedEvil | There are many different possibe encodings. |
| jaggz 2 | I wonder what I'd need to do to modify my stove so it can go below it's minimum temp (of 250 or whatever) |
| enthd | dhrosa: I only have some finite amount of power so I can only transmit up to some certain magnitude |
| jaggz 2 | 250f |
| tawr | anyone into knives / collect them / edc? |
| enthd | SpeedEvil: this is true |
| SpeedEvil | enthd: it's almost a pointless question. |
| Shawn286 | jeremyabel, yes there is, it appears balrog and I are the only ones that have said anything int here |
| Shawn286 | *in there |
| SpeedEvil | enthd: Which encoding is best depends on the signal frequency, the transmission environment, recievr complexity, acceptability of errors, .. |
| R0b0t1 | 'You have a Galileo V1 kit allocated from the Windows Developer Program!' |
| R0b0t1 | o/ |
| SpeedEvil | For example - if you're in an environment with lots of multipath - high frequency modulations may get completely shredded by that. |
| SpeedEvil | And you need to use OFDM or something |
| SpeedEvil | R0b0t1: gallileo v1? |
| tawr | RoBo_V, did you get it? they stopped sending them out |
| beaky | R0b0t1: is that the intel arduino thing |
| R0b0t1 | Well I think it's compatible with Wiring but it's also capable of running .NET code, iirc. |
| beaky | wow |
| R0b0t1 | Or whatever you compile for it. |
| R0b0t1 | SpeedEvil: Yes. Or was that a specific question? |
| azonenberg | tawr: I have several but i'd hardly call it a collection |
| SpeedEvil | R0b0t1: I was wondering what it was - I forgot |
| SpeedEvil | Oh - the crappy arduino thing |
| azonenberg | tawr: my two main ones i carry frequently are my leatherman wave and a victorinox swiss army knife, forget the model |
| R0b0t1 | Ah. |
| azonenberg | then for lab use, a scalpel with #11 disposable blades |
| R0b0t1 | SpeedEvil, it's like 2W and afaict has way better utilization of those 2W for computation than comparable ARM-based processors. |
| tawr | R0b0t1, not sure of that |
| SpeedEvil | minnowboard max ++ |
| tawr | CERN uses arm clusters for data acquisition / parsing |
| SpeedEvil | Though today - 'regular' motherboards are coming in under 10W |
| SpeedEvil | http://www.ebuyer.com/630828-gigabyte-ga-j1900n-d3v-intel-celeron-j1900-2ghz-vga-dvi-hd-audio-mini-itx-ga-j1900n-d3v |
| tawr | azonenberg, mind looking one up to see what you think about it? |
| R0b0t1 | SpeedEvil: Well yeah but this one's free! |
| azonenberg | tawr: maybe in a bit, kinda busy |
| R0b0t1 | tawr: I'll look into that, but I suspect it's due to customized silicon. |
| R0b0t1 | SpeedEvil: Yeah, I actually looked at those. It's not quite in the power/size bracket I would consider the Atom/Quark to be in. |
| SpeedEvil | RoBo_V: not quite |
| SpeedEvil | RoBo_V: but getting there |
| SpeedEvil | And - wel - my haswel I3 is at 22W right now - with a 5 year old PSU and .. |
| tawr | azonenberg, no worries bud |
| tawr | R0b0t1, have you seen the Vida mini-pc that just came out? |
| R0b0t1 | No |
| R0b0t1 | Link? I'm getting paperback porn. |
| tawr | http://www.newegg.com/Product/Product.aspx?Item=N82E16856501007 |
| R0b0t1 | Ahh neat |
| tawr | runs on 5v, dual core celeron, 32gb emmc |
| tawr | there is a new version coming out with 64gb instead (since there is no way to upgrade storage or ram) |
| tawr | but they are $130 on newegg with all the discounts, built in bng/bt4, dual monitors |
| tawr | i kind of want one just ot have one at that price |
| R0b0t1 | And has a mini-PCIe slot. |
| tawr | i believe it's taken up by the bgn/bt module |
| tawr | but i did not research too heavily |
| R0b0t1 | I picked some $50-with-$20-rebate AMD board b/c I needed a full PCIe slot. |
| R0b0t1 | http://www.latticesemi.com/en/Products/DevelopmentBoardsAndKits/ECP5PCIExpressDevKit.aspx - in a bit |
| lachesis | can anyone suggest an approachable writeup about usb charging? maybe as part of a datasheet or something? i'm reading the USB Battery Charging 1.2 test spec, and I feel like scooping my eyeballs out.. |
| jeremyabel | ooh sxy |
| tawr | the thing that caught my eye was you can run it from a 5v usb powerpack |
| enthd | Find the (an) n-partition of a circle meeting the following criteria: 1) The boundaries are a union of finitely many closed, simple, (finitely) piecewise smooth contours. no weird uncountable physically unrealizable cantor crap 2) the sum of arclengths of the each partition's contours' pieces is minimized |
| jeremyabel | whoa there mr. geometry |
| jeremyabel | there's the man I'm looking for! |
| GPF_1 | really. |
| GPF_1 | I have no money |
| tawr | lachesis, what do you need exactly |
| jeremyabel | GPF_1: a few days ago I mentioned I was having problems programming my avr cause I had another chip sharing the SPI pins, and you mentioned some stuff about using resistors but I forget exactly what it was |
| lachesis | tawr: mostly, how to implement the protocol to negotiate charging current; also, how to find devices that are compliant |
| Viper-7 | jeremyabel: its a cosine from god! |
| lachesis | (2) could be handled by (1) + a protocol sniffer |
| jeremyabel | Viper-7: lolol |
| GPF_1 | if you use a resistor network to the device that is using the SPI, you maybe able to overide it via the programmer. |
| tawr | lachesis, well, how in depth do you need |
| tawr | you can just 'force' 1A or 500ma with known resistor dividers on data pins for android/ios |
| GPF_1 | that is, if it is a loading problem. |
| lachesis | tawr: yeah, i want to see where that stuff is specified |
| tawr | it is not lachesis |
| jeremyabel | Viper-7: got me a 2V reference zener, modified your schematic, using Vin-28k+2k+2k+2k+33k-GND |
| tawr | it was proprietary and you have to nda to get the datasheets |
| jeremyabel | took me like 2 hours to figure out the damn terms that worked |
| lachesis | isn't there a standard now? |
| tawr | everyone else just reverse engineered it via trial and error |
| tawr | not for anything over 500ma that i'm aware of |
| lachesis | tawr: this is what i'm reading right now |
| lachesis | https://web.archive.org/web/20120119183605/http://www.usb.org/developers/devclass_docs/USB_Battery_Charging_1.2.pdf |
| tawr | anything over 500ma is proprietary and implemented, everyone copied apple and that's the 'unofficial' setup |
| jeremyabel | GPF_1: I 'maybe' able to? What would prevent me from doing so? |
| SpeedEvil | Everyone diddn;'t copy apple |
| SpeedEvil | tawr: then there are 'charger' standards since ~2011 |
| tawr | but android copied apple. a lot of aftermarket ROMS for android allow you to ignore the charger and just suck 100% of what's available |
| GPF_1 | you need to know the minimum current needed for the SPI device that is connected onboard. |
| lachesis | tawr: and wikipedia has 'Additionally, there is a Battery Charging Specification (Version 1.2 December 2010), which increases the power handling capability to 1.5 A but does not allow concurrent data transmission.[21] The Battery Charging Specification requires that the physical ports themselves be capable of handling 5 A of current[citation needed] but the specification limits the maximum current drawn to 1.5 A.' |
| tawr | yes SpeedEvil i'm aware, but in this case it's a bit more complicated |
| GPF_1 | possibly pull up R's will fix your problem. |
| jeremyabel | GPF_1: I shall investigate |
| GPF_1 | you do that. |
| GPF_1 | :) |
| tawr | when adafruit created the mintyboost she cataloged what it took to find out the chargign current setup |
| jeremyabel | cause I'd rather not like, have jumpers for freaking 4 pins hanging around |
| GPF_1 | if you had a scope, you could see what is going wrong with the signal. |
| tawr | and it was impossible without a NDA and she gives more information about that from her mintyboost page |
| jeremyabel | GPF_1: I do have one of those. |
| jeremyabel | and a logic analyzer |
| GPF_1 | then look to see the difference between the signals loaded and uploaded. |
| jeremyabel | word |
| lachesis | tawr: yeah, i've read the mintyboost page - seemed like an overly complicated solution that was just begging for someone to standardize :) |
| tawr | ? one of us has it backwards :P |
| GPF_1 | it's possible your onboard SPI is acKing.. |
| GPF_1 | or back talking. |
| Viper-7 | jeremyabel: yep i like it :D |
| GPF_1 | when it should not be. |
| lachesis | also, mintyboost only works at '5V output @ 500mA output' |
| SpeedEvil | tawr: mintyboost is old |
| jeremyabel | Viper-7: yeah, starting to get the hang of it. Verified everything in LTSpice, works like a charm |
| lachesis | SpeedEvil: can you link me to a charger spec or similar document? |
| tawr | lachesis, their new universal 5v boost power supply |
| tawr | has the resistor setup for 1A output for ios |
| tawr | err 1.5A and they tell you what the setup is |
| tawr | powerboost 1000 -- iirc |
| lachesis | tawr: powerboost does look nifty |
| jeremyabel | Viper-7: I power the comparator off the 3.3V regulated supply, not the battery, yeah? |
| Viper-7 | yeah |
| jeremyabel | cool |
| tawr | lachesis, im about to purchase one actually |
| Viper-7 | preferably with decoupling caps and such |
| tawr | to run it off a 3,400mah 18650 cell |
| jeremyabel | of course |
| lachesis | tawr: i just bought a xiaomi 10400 to keep in my bag as a power source for my cell phone |
| lachesis | way more consumer, but cheap as can be |
| lachesis | need to take it apart to make sure it isn't counterfeit, but it looks good on the outside |
| Slade- | when talking about propulsion, what is a low-pressure-ratio fan? |
| [3]nertia | Quadcopter? |
| Slade- | i mean i guess it'd be a fan with a low tip speed, but i dont know what else they'd do to it to make it noteworthy |
| SpeedEvil | https://www.youtube.com/watch?v=alZhcFSyoE0 - mike is awesome |
| Slade- | slower, but heavily angled? |
| darsie | Slade-: There is also #radiocontrol . |
| genewitch | what's the best way to clean electronics that possibly got rainwater inside? |
| darsie | genewitch: What device? |
| genewitch | MPPT solar controller |
| SpeedEvil | under power? |
| genewitch | No |
| darsie | ##radiocontrol * |
| SpeedEvil | Remove battery/power - place in oven at 60C for a day |
| Slade- | darsie, this has nothing to do with radio control? |
| SpeedEvil | If you can get the PCB out - place in oven at 95C for a few hours |
| genewitch | that dries it, should i put it in distilled water first |
| Slade- | darsie, think they'd know or something? |
| darsie | Slade-: k. They also talk about model air planes, I think. |
| genewitch | SpeedEvil, alright i'll try that |
| Slade m | darsie: yea. Reading a nasa presentation. So not really model planes |
| SpeedEvil | Slade m: the pressure ratio is simply the ratio of pressures on each side of a compressor |
| SpeedEvil | Once you get above a fairly small limit, this requires more than one fan |
| Slade m | SpeedEvil: I thought that too but they are electrically powered fans |
| SpeedEvil | Slade m: same applies |
| SpeedEvil | https://www.youtube.com/watch?v=Or6mIaSWZ8g |
| SpeedEvil | (not directly relevant) |
| Slade m | SpeedEvil: hmm. So nothing to do with spin speed? I mean I guess curve would matter |
| SpeedEvil | loosely related |
| SpeedEvil | higher speed, higher maximum pressure before a fan stalls |
| SpeedEvil | till you hit mach 1 |
| genewitch | actually only the very top looks like it got any water in it |
| genewitch | LCD isnt damaged or anything |
| Slade m | Ya. The paper is talking about mach 0.8 with low pressure fans. I can't even visualize that |
| genewitch | inverter looks clean too |
| genewitch | man i hate making cables |
| maicod | hi I tried using my 3.5 inch HDD mounting screws on an SSD (I didnt force it) but the holes of the SSD seem slightly narrower. is that correct ? |
| SpeedEvil | Slade m: exhaust pressure is a proxy for exhaust speed |
| genewitch | maicod, the mount screws are on the bottom |
| genewitch | and i think they're fine, not coarse |
| maicod | genewitch: yeah I saw the holes on the bottom but my screws don't seem to fit and those are the ones I normally use to mount a 3.5 hdd |
| Slade m | SpeedEvil: so you think they are using electrically powered turbines? |
| genewitch | HDD screws are coarse, i think you need fine, like cdrom screws |
| maicod | oh OK |
| maicod | I thought you meant 'they are fine' as in they are ok :) |
| maicod | sorry language prob:) |
| genewitch | some people say 'case screw' instead of 'coarse screw' but whatever |
| maicod | thanks for the help genewitch |
| maicod | genewitch: I'll get a 3.5 to 2.5 adapter and it comes with screws so I guess those will fit |
| maicod | wonder if they also fit in the bracket of my desktop (the outer ones) |
| SpeedEvil | Slade m: i have no idea |
| Slade-- | SpeedEvil, instead of speculating, its page 7 of this that i was struggling with http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20100036222.pdf |
| SpeedEvil | Look at the videos |
| Slade-- | 'The propulsion |
| Slade-- | system utilizes superconducting electrically |
| Slade-- | driven, distributed low-pressure-ratio (1.35) |
| Slade-- | fans with power provided by two remote |
| Slade-- | superconducting electric generators based on a |
| Slade-- | conventional turbofan core engine design' |
| Slade-- | ack sorry |
| genewitch | Slade--, i hate blogs too |
| Slade m | genewitch: pdf |
| Slade m | Hmm. So this means they are using a turbine to generate the electricity to be used to spin other turbines used for propulsion? |
| Slade-- | and they stress the use of supercapacitor in everything to demonstrate how it wont be terribly lossy? |
| hjf | class D is interesting.. |
| hjf | i was trying to build this amp wit TAS5630, |
| hjf | butthen i read about TAS5631 which is PWM input |
| hjf | and i thought ..wtf? why would you have a chip that converts analog to pwm and a separate chip for the power stage |
| hjf | turns out they have chips that receive digital audio directly (I2S) and convert to PWM |
| hjf | then you add a power stage |
| hjf | so you never have line-level analog audio |
| hjf | i wonder if i could use one of those PWM ICs and external MOSFETs |
| hjf | would be a lot easier than using this 44-pin power SMD thing |
| Slade-- | SpeedEvil, thanks for trying to explain :) |
| hjf | pretty awesome too since it can receive 24/192 data |
| jeremyabel | aw yeah pizza time |
| hjf | jeremyabel: what time is it |
| jeremyabel | pizza time! |
| lost_soul | :o no beer? |
| jeremyabel | nah, still more work to do |
| jeremyabel | normally yes |
| SpeedEvil | Slade-: this is working on technologies that may be 40 years out |
| SpeedEvil | Slade-: working out possible efficiencies of far-term propulsion |
| Slade- | SpeedEvil, yea. which was what i was interested in :) |
| FreezingCold | not baddd |
| FreezingCold | I get about ~3.9ms of a ping with powerline |
| FreezingCold | we're on different power meters too |
| Slade- | SpeedEvil, still doesnt make exact sense to me. but :) |
| nicexe | I need to drive 2 servo motors at 6.8V. My source is a 12V battery. Should I go with a step down converter or with a variable regulator? |
| Firehopper | most servos are most happy at 4.8 to 6volts. and not much above. |
| Firehopper | if your talking rc hobby servos. |
| GPF_1 | are you talking about steppers? |
| Firehopper | theres some high voltage servos that are happy at 8.4 but those are pricey |
| GPF_1 | from the talk it looks like it is just a simple PM motor with servo mechanics attached. |
| nicexe | ok lets say I need 6 volts. should I gow with a step down converter opr a variable regulator? |
| nicexe | *go |
| Firehopper | prolly a smps is best for that. |
| GPF_1 | does this servo have a position sensor? |
| nicexe | yes |
| Firehopper | servos tend to be power hungry |
| GPF_1 | use a buck current regulator. |
| GPF_1 | for the motor that is. |
| GPF_1 | with battery things, that helps to keep a constant max supply to the servo. |
| GPF_1 | however, the electronics on the server needs to be separated. |
| nicexe | wouldn't a regulator have a constant output voltage? |
| GPF_1 | SUre. |
| GPF_1 | I guess you could use a buck switcher in voltage mode. |
| ohsix | buns |
| GPF_1 | but you do need to good size cap on the output for those inrush moments so the buck switcher does not get upset. |
| nicexe | how much capacity should I seek for? |
| GPF_1 | how mnay amps total are you supplying? |
| GPF_1 | that dopends on the number of servos. |
| Firehopper | RIP joan rivers, passed away today at 1:17pm est in new york. |
| blight | hall sensors are nice :D |
| Firehopper | http://www.hollywoodreporter.com/news/joan-rivers-dead-legendary-comedienne-728845 |
| linux_probe | 0001ACTION feels dead after car wreck, sleeping whilst driving = no bueno it seems0001 |
| linux_probe | the sudden stop in a ditch was bad |
| GPF_1 | yes, the car tends not to go where you want it to with your eyes closed. |
| GPF_1 | Joan Rivers was a good looking woman for her aga. |
| nicexe | GPF_1: I.. don't know. Only one servo will work at a time. I have 2 of those http://www.servodatabase.com/servo/towerpro/sg-5010 |
| linux_probe | yeah, didn't work out so well for me, stupidest yet I was less than 1/8 mile from house on my own street >_> |
| Dazed_ | Any suggestions for an IC or something that can communicate over the same two wires that provide power to a device? For example, I would like to use the 12V (could be AC or DC) power lines to do RS485 communication with other devices connected to the same power rail. Ideally, I could throw a $1 IC into the project and call it good. Is that a hopeless pipe dream? |
| ikarus | Dazed_: hopeless pipedream |
| ikarus | that's not going to be a single cheap IC |
| GPF_1 | nicexe' that servo must has some tall gears in it, a 3 pole motor is kind of |
| GPF_1 | corse. |
| GPF_1 | of you know what I mean.? |
| GPF_1 | I have a few 3 pole DC brushed PM motors. |
| nofxx__ | Dazed_, was taking a look on data over power stuff, pretty abandoned |
| nofxx__ | wireless wins |
| nofxx__ | was even thinking it would be more reliable, but looks like suffers more than wireless (data over power) , but was looking over home AC lines |
| nofxx__ | Dazed_, what I've seen with pretty success is the use of eth cables, (4 non used in < gigabit connection) for power or RS485 |
| nofxx__ | or telephone |
| Dazed_ | interesting. This would be for an application in underground mines. Supposedly they do have a wireless system that works in that environment, but I don't have any details about what it is or 'networking' with it. I figured data over power would be a good way to minimize the wiring costs, since each unit on the network already needs power wires. |
| hagbard | I do believe they often use radio for communications in mines using what's called, 'leaky coax' |
| HTT-Bird | Dazed_: mine apps generally use a leaky coax system, and it would not be terribly hard to adapt that to some sort of leaky waveguide at microwave frequencies |
| hagbard | leaky coax >> leaky bladder |
| HTT-Bird | the main problem is protecting against the specter of flammable gases being ignited by whatever system is put in |
| drac_boy | hi |
| hagbard | drac_boy: sup |
| drac_boy | to get analog audio to eg a pci bus would had been a DAC right? (as in opposite of ADC) |
| drac_boy | or am I thinking backward |
| hagbard | DAC is for playing back music |
| hagbard | It's Digital to Analog. |
| hagbard | an adc is for recording. |
| drac_boy | right..long day so my memory is.well..yeah |
| drac_boy | ty |
| hagbard | what are you trying to do? |
| drac_boy | oh bit tired to do anything major now but just taking a quick look at what it might have taken to do dedicated audio interface before I.well..jut read some casual magazines then fall asleep? :-> |
| hagbard | drac_boy: dedicated audio interface for something in particular? |
| ikarus | drac_boy: real audio interfaces are external (for (electrical) noise reasons) |
| ohsix | . |
| ohsix | you know how badly a computer would fail fcc stuff if that were true and insurmountable |
| Dazed_ | Thanks for the leads, maybe I can dig around and find something about leveraging the existing systems. |
| drac_boy | ministereo in&out to a digital data bus with little parasitic overhead (sorry if thats not even a word but you get the idea) to the main cpu? mind you I hate these stupid winaudio and winmodem cards as they really have no actual purpose for existing in the first place at all but thats just what *I* think! |
| ikarus | drac_boy: and the one I use is nothing more then a USB 2.0 interface chip, an Atmel AVR (ATMega162) and a bunch of high quality DACs, ADCs and clock sources |
| ikarus | oh and the really expensive bit of fancy FET microphone preamps and such |
| ohsix | and not that most people will notice, or it matters; but usb audio class does some funky stuff ;D retiming in one of two places, and the OS usually sucks at it |
| hagbard | I use fake ones mounted in my computer. |
| drac_boy | atmel? hmm haven't checked them for anything for a long time.maybe I should take a look.. |
| ikarus | ohsix: this one doesn't use usb audio class |
| ohsix | even if it doesn't the problems are the same, or worse |
| ikarus | ohsix: however that does make it's drivers interesting to say the least |
| ohsix | at least with the usb audio class you know |
| hagbard | ohsix: dude, I bet ikarus has a full onb ocxo for his master clock. |
| ikarus | hagbard: if only :P |
| ikarus | but the driver does adjust it's clock based on the clock in the interface |
| ikarus | which is part of what makes the driver funky |
| hagbard | it's not just a fifo that the computer keeps topped up when it falls below a watermark? |
| ikarus | it also hogs one of the high quality interrupt sources on the host because of that |
| hagbard | because if there's anything a preemptive, multitasking operating system is bad at, it's deterministic timing. |
| ohsix | heh? |
| ikarus | hagbard: hence you throw in a HPET and a RT kernel |
| ohsix | the usb controller? |
| ohsix | the rt kernel does nothing notable that isn't already in mainline |
| ohsix | all you get with the patch anymore is upper and lower irq handlers |
| ikarus | I didn't buy it for this stuff btw, I just needed to tie a condenser microphone to my PC and have it work |
| flyback | hagbard, sounds like a veneral disease |
| hagbard | flyback: some argue it is. |
| ikarus | and at 90 euros, it was a pretty good deal |
| ohsix | there's nothing a usb device can do to hog an irq |
| ohsix | what makes one high quality and low quality? |
| drac_boy | hmm 8bit or 8bit+32bit avrs parameter filtering.. |
| ohsix | what are you looking at drac_boy? |
| dhrosa | drac_boy: in between, 20 bit@ |
| dhrosa | ! |
| drac_boy | ohsix oh I was just idly looking up the avr re audio . I'll have to say for $2-$3 bulk it sounds interesting |
| dhrosa | what's the weirdest word size that was popularly used |
| dhrosa | ? |
| drac_boy | dhrosa hmm one sec as I kinda recall something. |
| ohsix | motorola had a bunch of bit slice processors, you could pick |
| ohsix | there are cheaper mcu's too; though 2$ for an audio thing isn't bad |
| ohsix | i'd probably use some soc with usb in it, one of st's or something |
| flyback | what kind of audio |
| flyback | I read up on that motorola 14500 or whatever it was |
| flyback | wasn't really that much of a cpu |
| flyback | more like ladder logic or something vagely mcuish |
| flyback | but like 70's or so |
| drac_boy | ah took me a while but dhrosa here you go https://en.wikipedia.org/wiki/ND-5000 specifically the ND-505 version to be sold to russia at the time |
| drac_boy | while it may have been designed as a 32bit cpu . it still nevertheless only ran in 31bit mode permamently |
| FreezingCold | so managed to download pretty much all of my semester's textbooks |
| FreezingCold | woot woot |
| flyback | that doesn't really matter |
| ohsix | the arm is '31 bit' |
| flyback | CANUCK |
| ohsix | they use one bit to flag thumb |
| drac_boy | although..I wonder how many people resoldered the broken trace back on |
| FreezingCold | I can't believe people would pay for textbooks |
| flyback | too much dick sizing contest in mcu/cpu world sometimes |
| ohsix | the textbooks you buy for school are great |
| drac_boy | ohsix agreed |
| Casper | man that digikey order will be a royal pita to sort.. |
| flyback | CANUCK |
| FreezingCold | ohsix: but I got the same ones.. |
| FreezingCold | just they fit in my tiny tablet :D |
| ohsix | heh |
| ohsix | best of luck to you |
| FreezingCold | what's wrong with ebooks? |
| ohsix | diagrams and stuff are often set up for facing pages |
| drac_boy | freezingcold 1. where do I write? and 2. is it actually the legal one and not something that was likely rewritten by some random someone? |
| flyback | wow |
| ohsix | nothing is wrong, but when you need the real book for something, it is pretty shabby alternative |
| flyback | so many canucks chatting at once |
| FreezingCold | drac_boy: on paper. I don't write in my real books either |
| flyback | 0001ACTION bleeds out his eyes0001 |
| FreezingCold | drac_boy: what do you mean 'legal' one? |
| FreezingCold | who rewrites ebooks..? |
| drac_boy | ohsix heh..I have the same thing with certain magazines too..sometimes I have to literally put the magazine down and flip it to fold out a 2-page picture for a moment then flip it back and continue reading |
| drac_boy | freezingcold lot of people do.and pass it off as realistic copycats |
| drac_boy | even without that theres the problem of eg amazon/etc who seem to think its ok to strip ebooks at random notice anytime too |
| FreezingCold | these are all ripped ebooks. |
| flyback | hagbard, |
| flyback | that's why I really like those arm soc's that have a normal arm core and also a m0 core |
| GPF_1 | in otherwords, you ripped someone off? |
| flyback | you could use the m0 to handle the deterministic timing shit :) |
| FreezingCold | GPF_1: Correct, for the purpose of learning |
| GPF_1 | you don't need to learn to be a crook, that normally is born in you. |
| drac_boy | gpf_1 well said :) |
| ohsix | heh |
| ohsix | copyright infringement is not stealing |
| FreezingCold | ohsix: it's actually legal to pirate books for university in Canada.. |
| ohsix | they provide them? |
| GPF_1 | Maybe if the book is not published in CA. |
| ohsix | i don't see how going to university can be any sort of legal exception |
| drac_boy | mm looking at these avr's I'm starting to wonder if I could use them to work around the SoC having no pci bus to use for things like wifi.. |
| FreezingCold | no, the university would get sued to shit if they were known to allow it |
| ohsix | then it is not legal |
| FreezingCold | ohsix: pirating content for personal education is legal |
| FreezingCold | so for the individual it's legal |
| drac_boy | which bill quoted that freezingcold |
| ohsix | drac_boy: avr, really? |
| ohsix | you'd also have a serial wifi module or something expensive, too? |
| flyback | canuck_boy |
| drac_boy | ohsix wifi is pretty easy n cheap..the only problem is lack of bus for it |
| flyback | get what to do without pci? |
| flyback | usb? ethernet? wifi? they make them with a gpio, i2c, etc interface |
| flyback | 0001ACTION punts canuck_boy into orbit0001 |
| ohsix | it is a bit silly to try and manage peripherals you need at the edge and not change the thing you hook it up to |
| FreezingCold | drac_boy: looking it up.. |
| flyback | they make some damn fine chips infct |
| drac_boy | ohsix tell that to the companies..especially to allwinner for still having no bus host or anything at all |
| flyback | even when doing awefull pio they tried to make it perform as well as possible |
| drac_boy | freescale does have just one single pcie host but .. meh I'm not interested in trying to use a plx bridge chip |
| flyback | CANUCK_BOY |
| flyback | what are you trying to do |
| flyback | I might have seen it already |
| flyback | and fuck I am having a reaction to this shot this time |
| FreezingCold | drac_boy: http://laws-lois.justice.gc.ca/eng/acts/c-42/page-18.html |
| FreezingCold | 'Fair dealing for the purpose of research, private study, education, parody or satire does not infringe copyright.' |
| FreezingCold | > research, private study, education |
| FreezingCold | covered three times over lol |
| ohsix | drac_boy: if allwinner is the problem .. i don't follow |
| hesperaux | 'fair dealing'? |
| ohsix | FreezingCold: 'fair dealing' |
| FreezingCold | sounds fair to me |
| ohsix | sounds like a legal term to me |
| hesperaux | quite |
| drac_boy | ohsix..yeah and if you read more than one line you'll see that its not as clearcut anymore |
| FreezingCold | ohsix & hesperaux : http://www.usask.ca/copyright/basics/copyright-law/exceptions/index.php |
| FreezingCold | it's a case-by-case basis |
| FreezingCold | nobody has gone to court in a very long time, so none of those laws have even been tried really |
| ohsix | Fair dealing is an enumerated set of possible defences against an action for infringement of an exclusive right of copyright. Unlike the related United States doctrine of fair use, fair dealing cannot apply to any act which does not fall within one of these categories. |
| ohsix | drac_boy: eh? i'd read all the lines up to the point i'd typed that |
| hesperaux | i live in the US so it doesn't make any difference to me anyway |
| hesperaux | US law: you arrr a pirate |
| drac_boy | heh hespraux |
| ohsix | FreezingCold: http://en.wikipedia.org/wiki/Fair_dealing#Canada 'six principle criteria' |
| Shawn286 | copper pours are generating over static vias, when I am telling them to connect to them >.< |
| Shawn286 | can soemone help with this issue? |
| ohsix | suffice it to say what you are doing is not a-priori legal because reasons, but only when it has been evaluated by a court and deemed not legal |
| ohsix | loose talk man! |
| ohsix | it is kind of gross what the other things are in the bill that added the education stuff |
| Shawn286 | oh, thermal settings?? |
| Shawn286 | thats just confusing, but instead of using the settings I set in the copper pour tool, it lets me ovveride, and upon updating copper pours, they are connected |
| Shawn286 | weird |
| drac_boy | mm going let you talk about coppers..I'm going |
| Guest85687 | Coopering around? |
| Guest85687 | What software is that? |
| ohsix | infused olive oil is gr8 for sandwiches |
| Solarlux | Data direction output = 0 input = 1? |
| Solarlux | In microcontrollers? |
| Shawn286 | _abc__, I am learning to use a neat application suite called DipTrace |
| Shawn286 | :) |
| _abc__ | Ah i heard about it. Here I think.. |
| hesperaux | i like DesignSpark |
| hesperaux | pretty nice and free |
| hesperaux | Solarlux, usually that's the case |
| hesperaux | Solarlux, datasheet always says |
| teus_ | hmm, i have my amplifier at never more than 10% of the volume here |
| teus_ | what voltage divider do i need to limit the audio signal at 20% of the range of the amp |
| Solarlux | 0 input or 1? |
| Solarlux | For example |
| Solarlux | I want write it in my bootepad |
| Solarlux | and mmemorize |
| hesperaux | read the datasheet |
| Casper | teus_: you know that.. the volume button isn't linear? |
| teus_ | yes |
| teus_ | something about 20log |
| teus_ | i suck terribly at this |
| Casper | so if you set it to 1/10 that is not 10% |
| Shawn286 | yea, well so far everyones ignoring me when asking _abc__ :( |
| ohsix | hesperaux: i'll have to try and remember that |
| teus_ | i know |
| hesperaux | eh? remember what? |
| ohsix | designspark |
| hesperaux | ah. yeah |
| ohsix | what's the deal with the activation thing if it is free? |
| teus_ | hhmm i should know the gain of hte amp to know anything sensible |
| hesperaux | activation is free |
| hesperaux | you have an account for it cuz it can download models/symbols from their library online |
| hesperaux | the program is unrestricted |
| cne | hi, i'm doing a basic circuit theory question (just ohm's law and kirchhoff's current law) and i've confused myself a little bit. in the context of http://puu.sh/blZZr/2460491361.png, how exactly is it determined that R_a = 1? i tried working through it but failed |
| hesperaux | apparently RS/Allied have a couple of other free CAD tools too |
| ohsix | yea they say all that on the web page, getting parts is good enough for me |
| teus_ | i think ill start with -20dB |
| ohsix | tracking usage is probably something you'd want to do to develop it too |
| hesperaux | yeah |
| hesperaux | it's surprised me how many things are in the library, but i've had to make a few symbols before. They have a video tutorial on youtube for how to make your own symbols |
| cne | from what i can tell, the voltage drops across the three branches are equal so 18 V = 6i_x is consistent with the given i_x = 3 A |
| Solarlux | For example myvariable = (int)PORT4.DR.BIT.BIT0; |
| Solarlux | PORT4.DR.BIT.BIT0; how can i ma |
| cne | the current thru the R_a branch would therefore be 18/R_a no? which leads me to using kirchhoff's current law to state |
| Solarlux | PORT4.DR.BIT.BIT0; this value its only number |
| Solarlux | Why itcan access Direction register? |
| cne | the 13 A splits into i_x, 18/R_a, and the given 8 A ergo 13 A = i_x + 18/R_a + 8 A |
| cne | so 13 A = 11 A + 18/R_a therefore R_a = 9 ohms |
| cne | but the given solution states R_a = 1 ohm and i have absolutely no idea where i went wrong |
| ohsix | hesperaux: yea i see a lot of good in being connected with someone like rs, they've got 3d parts and shit from the vendors already |
| hesperaux | yeah |
| hesperaux | not a fan of their pricing, lol, but i'll take the free software xD |
| cne | http://puu.sh/blZZr/2460491361.png the problem again in case anyone feels generous enough to help me |
| ohsix | https://play.google.com/store/apps/details?id=com.theophrast.droidpcb&hl=en heh |
| ohsix | i hate what mobile has done to games and shit, but i like to see original small scale software and how they end up doing a 'big thing' on a small device |
| hesperaux | cne, you need to use loop equations as well as node equations in order to come up with a sufficient number of equations to solve for variables vx and Ra |
| ball | What has mobile done to shit? |
| Bird lappy | ball, mobile's kind of forced games to oversimplify |
| hesperaux | i like those though. when i play a mobile game i want to be able to start and stop it at any time |
| Bird lappy | in some of the same ways the early consoles and arcade machines did |
| hesperaux | i play a lot of puzzly or tower defense type games though |
| The_Coolest | So I'm debating if I should have a ferrite bead in front of the DACs digital VDD pin + cap or not |
| cne | hesperaux: we don't need to solve for v_x, do we? |
| hesperaux | cne, i think you can use thevenin/norton simplification too |
| hesperaux | 0001ACTION hasn't thought about it that much0001 |
| Bird lappy | The_Coolest, go ahead and slap it in there |
| HaltingState | how do i tap a screw with a cnc machine? is there a bit for this? |
| Guest86407 | hello all. |
| Bird lappy | what should I look for if my nodal/mesh equations appear right, but cancel out excessively (or not enough) when I try to solve them? |
| hesperaux | HaltingState, don't think you'd usually use a cnc for that, unless it's a lathe |
| HaltingState | i have a hole and i want it to be threaded |
| hesperaux | and you'll need a die cutter |
| hesperaux | oh you mean tap a hole, ok |
| The_Coolest | Bird lappy these are the beads i got http://www.digikey.com/product-detail/en/CIM21J252NE/1276-6377-1-ND/3973849 |
| Guest86407 | i'm trying to simulate an AWGN channel of some complex channel strength, with some SNR. |
| Shawn286 | gah, I can't figure out how to remove copper pour's empty spaceing |
| Guest86407 | how much gaussian noise do I add to the signal, post multiplication with the channel strength? |
| cne | hesperaux: to solve for v_x shouldn't it just be the 18 V drop across the parallel branches + the drop across the first resistor (V = 13 A * 5 Ohms = 65 V) for a total of v_x = 83 V? |
| hesperaux | HaltingState, i've done that on a lathe, manually. don't know if it can be done with CNC without really good brushless drives |
| cne | hesperaux: i'm familiar w/ those but we're expected to solve it using just KCL and Ohm's law |
| hesperaux | either way you can try to use a tap and have it drill and back off really fast. might ruin the part though |
| cne | it's a practice example in the textbook btw |
| Bird lappy | cne: nodal *IS* KCL+Ohm's law, in a nutshell |
| hesperaux | cne, i see that it gives you the answers so i'm not concerned with that ;) I have to look at this more carefully. It's been years |
| hesperaux | i've had a bit of scotch too, so who knows how correct i'll be :P |
| The_Coolest | Bird lappy any idea if these beads are any good? |
| Guest86407 | so say, for example, I want to simulate a channel with strength '0.5-0.5j' and SNR 5. What gaussian distribution do I add to it to get that SNR? |
| ohsix | hesperaux: lots of people like tower defense and stuff |
| hesperaux | you know that 10A is split between RA and 18V supply (I believe it is possible for current to flow into the 18V supply) |
| ohsix | with the markets and the price points (free to play, 99c) you get a shitload of clones and the same stuff people like over and over again |
| hesperaux | yeah that is true |
| hesperaux | some clones are better than the original though |
| ohsix | there's nothing new, i've had a thing for like a year and i've yet to find something better than like, youtube; to even have the thing |
| hesperaux | everyone's trying to make a buck (exactly a buck :P) |
| ohsix | this is with a lot of concious effort to check everything visible out, and stuff that isn't too |
| The_Coolest | ohsix all you need is to make enough bucks |
| hesperaux | i've got a couple of android apps in progress, but they are things that aren't done right in existing apps |
| zigggggy | 0001ACTION gives hesperaux 99 cents0001 |
| hesperaux | zigggggy, dude thanks brah |
| zigggggy | :) |
| hesperaux | 0001ACTION buys bitcoins with the 99 cents0001 |
| zigggggy | :O |
| The_Coolest | 0001ACTION steals 30 cents from hesperaux0001 |
| hesperaux | lol |
| ohsix | when you find something that is ok it fits its price point and it is over, or it is something like an infinite run game that never finishes, or you'd have to play a thousand hours to unlock everything |
| Frogging101-chan | Shitcoins. |
| zigggggy | hi frogging |
| hesperaux | The_Coolest, too late I used a really good key |
| The_Coolest | :[ |
| zigggggy | turn that frown upside down The_Coolest |
| ohsix | you shouldn't want to play a game that just unlocks stuff to play the same game slightly different, it is the only type of addictive gameplay that i entertain even a little; because i can't help it |
| The_Coolest | hesperaux all those app stores usually take 30% from every transaction |
| The_Coolest | zigggggy I'm bummed |
| hesperaux | cne, you can figure out what v_x is by: 18V - 13A*5ohm - vx = 0 |
| ohsix | i play them at least long enough to see that they're bullshit, then use a cheat engine to get the iap/coins whatever to see the end game (pro tip, there never is an end game, they schedule the unlocks so releases stay ahead of anyone playing it the way they intend) |
| The_Coolest | all i need is a couple more deals like i just struck to get the $ to fix my car |
| hesperaux | The_Coolest, didn't know that. huh. |
| hesperaux | 0001ACTION will charge .99USD + .3*.99USD0001 |
| The_Coolest | heh |
| ohsix | bp found grossly negligent in deepwater disaster |
| ohsix | penalty up to 18 billion dollars |
| ohsix | https://www.google.com/finance?q=bp&ei=PxkJVJD0HcariQLhtIDwBQ heh |
| cne | yeah hesperaux thats what i ended up doing :p |
| hesperaux | cne, doesn't seem like the right answer to me but i'm slightly buzzed right now so eh |
| jnewt | need some help troubleshooting a phone line. i have two lines coming into the house. if i plug my 'test phone' into the outside socket i get a dial tone. Inside, only one of the lines has a dial tone. do i need to call telco? |
| ohsix | hesperaux: how easy is it to get svg shapes into designspark? |
| cne | but i'm not sure how knowing v_x helps me discover what R_a should be |
| hesperaux | cne, that equation inherently assumes that no current flows into the 18V supply I think |
| cne | oh |
| hesperaux | ohsix, i don't know if that's possible. You draw them in the app itself |
| jnewt | i don't know how to check each line at the outside box |
| cne | hmm |
| hesperaux | cne, i'm pretty rusty. sorry. This is embarrassing :) |
| hesperaux | it tells you that ix is 3A too, so you can verify vx that way. 13A*5 + 6*3A = vx |
| jnewt | everything i google says that if i have a dialtone at the box, the problem is wiring in the house. can't google up how to check each line outside |
| hesperaux | that says that v_x is 83V, which isn't the same as from the other equation, so one of those is wrong |
| Bird lappy | The_Coolest, no |
| ohsix | hesperaux: ohhhhh the registration is for the user support forums too, clever |
| cne | they both say 83 i thought |
| hesperaux | ohsix, didn't realize that. nice |
| cne | the only difference is that you replaced 18 with 6*3 |
| Bird lappy | ohsix, ya. the weirdo thing about Deepwater Horizon is that what happened there could happen *anywhere* |
| hesperaux | cne, nah, before I had a sign flipped |
| cne | ty btw hesperaux |
| The_Coolest | Bird lappy no as in no idea? or no as in they are no good |
| Bird lappy | The_Coolest, no idea |
| cne | oh ic |
| hesperaux | cne, no problem; hopefully i am useful here |
| ohsix | Bird lappy: welllll it is a bit of a stretch to say that, but it definitely was plausible and did happen there |
| Bird lappy | ohsix: the Deepwater Horizon BOP very likely activated in deadman during the initial stages of the disaster |
| hesperaux | anyway, if you know the voltages and the current in the outer loop, you should be able to combine the two middle resistances (RA, 6) |
| Bird lappy | but since an earlier manual action had blocked the flow of oil onto the platform if only briefly |
| Bird lappy | pressure buildup in the pipe string caused it to buckle, preventing the blind shear ram from shearing it |
| ohsix | it has been a while since i cared to remember what happened, that sounds familiar tho |
| Bird lappy | had the pipe not buckled, it'd still have been a messy situation with the fire up top |
| hesperaux | since you'd know the resistance up top (5ohm) and the two voltages on the outside, you should be able to use the final nodal equation to solve for RA |
| cne | hesperaux: why is the sign different between those two equations you came up with? |
| hesperaux | let me see if it works. i'll try to write it on paper |
| Bird lappy | but the ensuing ecological disaster would have been a total non-event. |
| cne | hm |
| hesperaux | cne, not sure. i might be dumb. 18V was a voltage rise, but the current across 5ohm was a drop, and going into the vx supply is another drop (-, -) |
| hesperaux | 0001ACTION gets a paper0001 |
| ohsix | hesperaux: they make you add a company name and title when you activate |
| hesperaux | one thing that annoys me is that it says the 18V supply 'delievs' 8A. Not sure what that means exactly |
| hesperaux | ohsix, i put like Mr. Me and TheAwesomeCompany or something |
| hesperaux | I put BS in there |
| ohsix | did |
| ohsix | this is the kind of thing that an mx revo is impossible for, need middle mouse button agh |
| hesperaux | it doesn't have a middle button? fail |
| ohsix | is there no way to pan without it? |
| hesperaux | what are you panning? |
| ohsix | yea it has a wheel, you can middle click it but it is so hard to do that i just don't consider it to have a middle mouse button |
| hesperaux | lol |
| cne | hesperaux: i guess they just mean 8 A passes thru it |
| cne | odd terminology |
| cne | 8 A from + to - in accordance with PSC |
| hesperaux | ah, ok |
| hesperaux | if that's true, then you know the current across RA, and the voltage at that node |
| hesperaux | which means you know RA |
| hesperaux | it's just 10 A into RAtop = 8A + RA_current |
| hesperaux | and you know the voltage at that node is 18V |
| hesperaux | doesn't give the right answer though |
| hesperaux | 0001ACTION goes back to paper0001 |
| cne | when i work it |
| cne | i keep getting R_A = 9 Ohms |
| hesperaux | yeah that's why one of our assumptions is wrong |
| ohsix | heh designspark can't import dxf files with splines |
| cne | i'm not a catholic so i'm open to the idea the book is wrong hesperaux :p |
| hesperaux | lol |
| hesperaux | cne, i'm going to a system use loop equations to solve it |
| cne | ok |
| cne | im gonna use one of those interactive circuit solver applets |
| cne | and see if it agrees |
| ohsix | this is a good reason to get a new mouse, awesome |
| ohsix | i was hung up on liking the wheel on the revo |
| cne | cne: i think the 8 A is supposed to be -8 A |
| cne | that gives R_A = 1 Ohm |
| hesperaux | ah, see that's telling you that the current flows into the supply |
| hesperaux | not a good circuit to live by |
| hesperaux | but i'm bothered by the solution. seeing if a system of eqn's will find the answer properly |
| flyback | hey gigs |
| jeremyabel | hey flyback |
| T1960CT | Hello, does anyone here know of a way to get USB or networking capabilities ported through any of the following ports?: PS/2, Serial 9pin, VGA or 25pin parallel? |
| jeremyabel | timbur: you can get Serial through serial or 25 pin parallel |
| ohsix | serial 9 pin has slip connection |
| jeremyabel | and USB via serial |
| ohsix | sounds like you have a very bad situation and should do anything else first |
| T1960CT | I cant find anywhere that has the right gender for it |
| jeremyabel | lol yeah |
| cne | hmm hesperaux |
| T1960CT | It's all cables to get older port connections on new hardware not the other way around |
| jeremyabel | ohsix: decoupling opamp supply, 1µF ceramic should do it? |
| ohsix | jeremyabel: no idea |
| ohsix | heh |
| Shawn286 | T1960CT, I give my old hardware internet through SLIP |
| jeremyabel | godddddd |
| ohsix | gotta calculate it, that value is probably sufficient but i couldn't say |
| Shawn286 | via serial ports |
| jeremyabel | I'm so tired of calculating today! |
| jeremyabel | literally spent 3 hours with my head in my calculator today.. |
| hesperaux | cne, why would they say the 18V supply delivers 8A of current, and then label the current i_x and 13A current on the diagram |
| XDS2010 | question: are there any competitive products to the new JBL Pulse ? |
| flyback | I so want to murder chris tucker in this movie |
| hesperaux | are they trying to be vague about the direction of the 8A current on purpose? |
| ohsix | XDS2010: ##electronics != consumer electronics, try #hardware |
| jeremyabel | flyback: you're not understanding the words that are coming out of his mouth? |
| XDS2010 | ohsix: sorry thanks |
| Bird lappy | T1960CT, yeah, SLIP/PPP over serial is your best bet |
| R0b0t1 | XDS2010: The what is a JBL Puls? |
| R0b0t1 | We can figure out how you measure its efficacy |
| flyback | I want to put my hands around his neck and never let go till the worms are all dead |
| XDS2010 | R0b0t1: its pulse |
| R0b0t1 | and then you can decide if it's a good idea to buy |
| XDS2010 | |
| R0b0t1 | NO, PEON - PROVIDE DATA |
| cne | hesperaux: i'm guessing so |
| R0b0t1 | It shows me you're not a complete asshat |
| cne | they're probably testing my knowledge of PSC |
| XDS2010 | R0b0t1: calling me names won't help you |
| hesperaux | cne, PSC? |
| R0b0t1 | XDS2010: I never called you an asshat, is the issue - merely suggested a way to test if you are an asshat. |
| jeremyabel | I did hear him call you a douchecanoe though |
| jeremyabel | behind your back, after math class |
| hesperaux | probably because that word sounds fun |
| T1960CT | Do you think something like this would work on different OS's? (experimenting a little) http://www.ebay.com/itm/New-9-Pin-Serial-Port-to-RJ45-Cat5-Ethernet-LAN-Adapter-Cable-/390666272325?pt=LH_DefaultDomain_0&hash=item5af5863e45 |
| XDS2010 | R0b0t1: and anyways its a new product i wouldn't know how to describe it. its more or less a portable bluetooth speaker with LED synthesizer visualizer in the front |
| WeatherOnDVR | <-- useful? |
| R0b0t1 | That's a picture of a cable. |
| R0b0t1 | What? |
| Bird lappy | T1960CT, that's likely a pinout adapter, of the type you use with a rollover RJ-45 cable for making console hookups to Cisco routers and the likes |
| R0b0t1 | Check the pinout of your device and the pinout of that cable. |
| hesperaux | T1960CT, they use those cables for RS485 |
| R0b0t1 | It's available, somewhere. |
| ohsix | windows won't do internet sharing over serial anymore |
| hesperaux | we have some smart PDUs at the old datacenter i worked at that use those for communication |
| cne | hesperaux: passive sign convention |
| cne | hold on let me install a proper irc client brb |
| T1960CT | Well it says serial to cat5 so wouldnt I be able to plug it directly into my router? |
| hesperaux | cne, oh, you mean choosing a direction of current and sticking by the convention for all your calculations? |
| Bird lappy | no |
| hesperaux | T1960CT, absolutely not |
| ohsix | >current direction |
| hesperaux | just cuz the wires touch doesn't make it an ice cream truck |
| R0b0t1 | T1960CT: Maybe. What's on the other end of the serial to cat5 cable? |
| hesperaux | you can put that on your next cafe press shirt - my permission given |
| ohsix | i smelled a hazard in answering |
| jeremyabel | I mean, what if it was an icecream truck? |
| T1960CT | Hahaha ok, I really dont know about hardware, as you can tell |
| ohsix | away! |
| jeremyabel | lol |
| R0b0t1 | T1960CT: Pictures? Link to google results? |
| T1960CT | For the computer I'm using? |
| hesperaux | china's idea when they put up this listing: 'it converts the thingy for 9pin serial to the thingy for rj45, so we'll call it an ethernet LAN adapter cable' |
| hesperaux | i seriously have like 8-10 of these in my bin |
| hesperaux | i think cisco uses them |
| Bird lappy | +1 hesperaux |
| Bird lappy | and yes, I remember them from networking labs |
| R0b0t1 | 0001ACTION blinks0001 |
| R0b0t1 | T1960CT: The serial cable goes directly into the computer? What on the computer? |
| hesperaux | they use some kinda custom shit to communicate with the cable. Maybe they thought router console would be better using a serial port, rather than another rj45 on a switch with 48 other ports (to avoid confusion perhaps) |
| hesperaux | whatever the case amy be, I lost the game |
| T1960CT | R0b0t1: do you mean the OS or the hardware? I dont have a cable for it yet, I'm looking for one to get it online. |
| hesperaux | cne_, i see you are back. |
| hjf | check out my groud plane guise |
| hjf | http://i.imgur.com/l5F2eL3.jpg |
| hesperaux | from before: cne_, oh, you mean choosing a direction of current and sticking by the convention for all your calculations? |
| R0b0t1 | T1960CT: What are you plugging the cable into? You should be able to identify a part. |
| hesperaux | dude your ground plane is so groundy |
| R0b0t1 | Not software, but a physical thing. |
| hesperaux | much ground. such plate. wow |
| hjf | top side: http://i.imgur.com/6kOT8Fg.jpg |
| R0b0t1 | T1960CT: Barring special hardware you will not be able to do what you want. |
| R0b0t1 | You're looking for hardware that might be special. |
| hesperaux | hjf, you left some flux there bro |
| hesperaux | nice delicious sticky flux |
| R0b0t1 | GLORIOUS NO-CLEAN FLUX? |
| hesperaux | i hate how sticky it gets |
| hjf | R0b0t1: no that's for fags i use rosin |
| R0b0t1 | DEATH TO THE HERETIC |
| hesperaux | lol |
| hesperaux | hjf, question: did you make this board at home? |
| R0b0t1 | T1960CT: You might have to take the case off, get a screwdriver I guess. |
| R0b0t1 | And/or lots of pictures. |
| hjf | hesperaux: yes |
| hesperaux | cne_, this problem makes me upset in a detrimental, I-remember-this-crap kinda way |
| hesperaux | hjf, nice man. what method did you use for that? |
| hesperaux | i'm guessing photolith |
| hjf | hesperaux: toner transfer |
| hesperaux | hjf, you get more street cred |
| hesperaux | nice job |
| hesperaux | done that before and it's a bitch |
| hesperaux | one time I made a PERFECT transfer. etched the board all out |
| T1960CT | https://www.filepicker.io/api/file/wbvorA7HQViP94GZWCCw |
| T1960CT | This is what I have available |
| hesperaux | realized later when I went to solder it that the IC was backwards. Which means the transfer was mirrored. |
| hesperaux | i raged hard |
| hjf | hesperaux: i do that sometimes. thats why i add text |
| hesperaux | T1960CT, yeah no it won't work for htat |
| hesperaux | hjf, there you go |
| hjf | hesperaux: i use vinyl for toner transfer |
| T1960CT | Fuck so is there no way whatsoever to make this work? |
| hjf | and GreenTRF |
| R0b0t1 | T1960CT: Contextualize picture pls. |
| R0b0t1 | I dunno maybe |
| R0b0t1 | probably not |
| hesperaux | T1960CT, is your goal to provide LAN to the laptop? |
| hesperaux | if so, then there's no way to make it work |
| R0b0t1 | It's one of those things I assume you'd know about if it was possible, b'cus, that's how this thing usually works. |
| cne_ | haha hesperaux |
| cne_ | i have another one maybe you can help me with :p |
| cne_ | this one i'm stumped on |
| T1960CT | Damnit |
| hesperaux | cne_, i'll take a look but no guarantees |
| hesperaux | energy levels decreasing |
| hesperaux | hjf, i used these expensive-ass transparencies. You know, the kind for overhead projectors that you can print on with a laser printer? |
| hesperaux | 40 bucks for one box of em |
| hagbard | I like the huge gaping hole in the side of that laptop. |
| hesperaux | they work really crappily because they are so stiff that when you try to pull them off, they shear the toner off the board and it stays on the sheet |
| hesperaux | hagbard, that's for the SSD bro |
| cne_ | hesperaux, http://puu.sh/bm38f/8ec6e4c199.png |
| hagbard | hesperaux: haha, no way, That's for the fiber optic port |
| hjf | hesperaux: yes. try the vinyl one day |
| hesperaux | ohhh yeah |
| SpeedEvil | hesperaux: 'i raged hard' |
| hesperaux | fiber. nice |
| hesperaux | SpeedEvil, ? |
| SpeedEvil | hesperaux: take the board, glue it to a blank bit of FR4 - and then sand off the top bit of FR4 doewn to the copper |
| hesperaux | SpeedEvil, ahahah |
| hesperaux | genius |
| cne_ | hesperaux, i applied kirchhoff's current law to the node where I_B, I_E meet to write I_B + 150*I_B + I_C = I_E |
| hesperaux | +5000 street cred for that |
| hesperaux | what the hell kind of circuit is this crap |
| cne_ | hesperaux, but i have no idea how to relate I_C, I_E to solve |
| yan_ | hi, i'm trying to get some intuitive understanding for basics and capacitors specfically. can someone ellucidate why the capacitor in this circuit has any effect on the signal going into the second buffer?: http://i.imgur.com/Te9aHni.png |
| hesperaux | damn, a BJT model. That's actually a thing. |
| Bird lappy | T1960CT, I'd use an old Linux box with an Ethernet card and a serial port as a SLIP or PPP to Ethernet bridge |
| cne_ | hesperaux, it's a basic model for a bjt transistor (I_B, I_C, I_E being base/collector/emitter currents) |
| hesperaux | cne_, you'll get to do that one a lot in circuits 2 |
| SpeedEvil | yan_: a capacitor doesn't like voltage changes - it resists them by needing to be charged or discharged |
| hesperaux | cne_, ok so your nodal equation that you said sounds right to me, first of all |
| yan_ | SpeedEvil: i understand that part, but why does the the current 'take that path'? (not sure how to phrase it correctly). isn't the path through the second buffer the path of least resistance? |
| T1960CT | Bird lappy: What about this though: http://www.ebay.com/itm/Xircom-Parallel-Port-10Base-T-Ethernet-LAN-Adapter-PE3-10BT-Module-Cable-/201134340611?pt=US_Laptop_Network_Cards&hash=item2ed48a7a03 |
| Bird lappy | o.O wow |
| SpeedEvil | yan_: no |
| hesperaux | cne_, you can also claim that IC*1K + IE*1K = V2, since IE and IC are defined as the actual currents right there |
| SpeedEvil | yan_: current does not take 'the path of least resistance' |
| SpeedEvil | yan_: current takes _all_paths_it_can_ |
| SpeedEvil | yan_: in proportion to the resistance of those paths |
| SpeedEvil | yan_: also - the input of a buffer like that has 'infiinite' resistance - it draws amost no current - nanoamps |
| yan_ | SpeedEvil: sure, wasn't phrasing myself accurately initially, but after ~5RC time, the capacitor will not have any effect, right? |
| hesperaux | it's unfortunate that 'the path of least resistance' is a thing |
| R0b0t1 | >universe is pretty great except for thermodynamics |
| hesperaux | cne_, my brain tends to explode when I see the voltage source connected between two subcircuits, but I guess just ignore that and use the nodal equations and loop equations for each half |
| yan_ | SpeedEvil: have not considered that CMOS logic (incl. buffers) have super high internal resistance, but makes sense |
| hesperaux | R0b0t1, thermo bothered me. it was very simple and yet I failed hard |
| hesperaux | yan_, nevertheless, that's not why the capacitor affects that circuit, primarily |
| cne_ | <hesperaux> cne_, you can also claim that IC*1K + IE*1K = V2, since IE and IC are defined as the actual currents right there |
| hesperaux | yan_, the capacitor will look more and more like a wire the more discharged it is (even though electrons don't actually jump across a capacitor, but that's physics). hence, for large capacitors like the 1000uF in the diagram, if the current sags for a significant amount of time, the capacitor will lose enough charge for the voltage to decrease. When the voltage decreases across the capacitor, the first buffer will source current to fill it back |
| hesperaux | up again (so current 'flows' to ground through the cap). Man that's got to be my worst explanation ever |
| cne_ | right but i don't know V2 so i'm not sure the extent to which that is useful |
| cne_ | i had taht written down tho |
| hesperaux | cne_, perhaps you can solve for I_B though, using the left hand side of the diagram? |
| cne_ | so you just gave me the loop equation yes hesperaux ? |
| hesperaux | cne_, yeah |
| cne_ | hesperaux, i mean the left side is just V_1, R_1, R_2 with no actual values |
| hesperaux | I see a relationship between the two sides via IB |
| hesperaux | cne_, you know that V1 = R1*I1+R2*I2, right? and you know that I1 - IB = I2 for the left side |
| yan_ | hesperaux: i understand the physics behind a charging/discharging capacitor, i'm just struggling to build an intuition of how it effects voltage across itself. i realize that at t=0, it has no charge and will begin to build its internal field, but i don't understand why that causes the voltage between A and B to be 0 at t=0. |
| cne_ | hesperaux, i see V1 = R1I1 + R2I2 for sure yeah |
| cne_ | that's just the left loop eq |
| cne_ | hesperaux, I1 - IB = I2 i see as well yes |
| R0b0t1 | yan_: Nothing's moved yet. |
| R0b0t1 | The electrons are stationary.. |
| hesperaux | cne_, i haven't thought far enough ahead to determine if those equations are useful, but usually my first thought is to write as many equations as possible, and then eliminate redundancy and solve the system |
| yan_ | R0b0t1: heh, i meant at t=epsilon in that case |
| cne_ | do you think they want an answer in terms of V1, V2? like there's not enough given to find numerical values for I_B, I_C? |
| cne_ | oops |
| cne_ | I_C, I_E |
| R0b0t1 | yan_: V !=0 at t=ep. |
| hesperaux | cne_, probably, they want it in terms of any variables that exist |
| R0b0t1 | But when V = 0, the same is true, no electrons are moving. |
| hesperaux | cne_, so come up with a system, treating R1, R2, V1, etc as constants, then solve for IC and IE in terms of their values |
| cne_ | hesperaux, what about the voltage source just chilling between the loops? |
| hesperaux | cne_, this basically gives you an equation for the model of the BJT, which is supposedly going to be useful |
| cne_ | hmm |
| hesperaux | cne_, i would ignore it. It's merely there to show a linkage in the physical model I believe |
| hesperaux | that feels wrong, but eh |
| cne_ | hesperaux, is there a nodal equation i can write between I_E, I_C? |
| hesperaux | cne_, IE = IC + IB heh |
| cne_ | youre neglecting the CCCS :p |
| cne_ | I_E = I_C + 151 I_B ya |
| hesperaux | oh, my bad. you're right :D |
| cne_ | thank you though |
| cne_ | you've made me feel a lot more comfortable w/ the material |
| hesperaux | that's surprising, but good |
| cne_ | the fact i'm making sense enough to have a coherent conversation about this stuff is a good sign |
| hesperaux | indeed. btw, my justification for ignoring the bridging voltage source is that you know it is passing IB, and it has no circular path to itself |
| cne_ | yeah i see hesperaux |
| yan_ | hesperaux: can you expand on your earlier explanation of the RC circuit? e.g. why would the capacitor losing charge cause the voltage to decrease? (i assume since it's providing its own voltage and reducing the voltage between A and B?) and what do you mean that the first buffer will source current to fill it back? (my mental image of capacitors is that they need current to fill them, but the rate at which this happens is dependent on voltage) |
| dhrosa | yan_: that model is flawed |
| dhrosa | yan_: it's dependent on the input voltage and any impedance between the cap and that voltage |
| dhrosa | yan_: a theoretical capacitor will instantly charge with a voltage applied to it |
| hesperaux | i believe the theoretical model of a capacitor does not imply instantaneous charging |
| dhrosa | yes it does |
| hesperaux | it's not logarithmic? |
| dhrosa | only with a resistor |
| dhrosa | also that's 1 - exponential |
| dhrosa | not logarithmic |
| dhrosa | a capacitor with no resistor will draw an infinite current for an infinitely short period of time and instantly charge to the source voltage |
| hjf | so i think i'll just build the TAS5630 amp with components i have |
| hesperaux | yeah, you're right. i don't know what i'm on |
| hjf | it needs 2.2uF MLCC |
| hjf | i can only get 1uF ones here |
| R0b0t1 | hesperaux: The theoretical model does, yes. |
| hjf | i guess i could just stack two? |
| hesperaux | yan_, your statement about it being dependent on voltage is true, only because of the resistance in the circuit which limits the current |
| hesperaux | i believe that accomodates what dhrosa said as well |
| hesperaux | at t=epsilon, with a step function input to the first buffer, a voltage is presented at B, for which a current is sourced through the 15K resistor. The capacitor creates an electric field to compensate for the potential difference between its top plate and ground. This field exists because of the air gap preventing the charges from physically flowing to ground. The field is generated at a speed proportional to the current sourced. Because it ta |
| hesperaux | kes energy to 'fill' the capacitor, it appears as though the input to the second buffer is a smaller voltage than that of the first buffer's output (i.e. there is a voltage measured at A:B) |
| hesperaux | once the capacitor is charged, the voltage at A:B should become 0 |
| hesperaux | am I correct guys? |
| hesperaux | or am I forgetting a voltage drop across the R |
| hesperaux | 0001ACTION is tired0001 |
| R0b0t1 | I like pictures more |
| R0b0t1 | and am too lazy to draw my own |
| hesperaux | yan_, i'd recommend hooking it up to a 10Hz generator in real life and seeing what it does |
| hesperaux | measure A:B on a scope, against the input with respect to GND |
| cne_ | yo hesperaux |
| hesperaux | yo cne_ |
| cne_ | I_C = 1/20000 (10V_2 - 151), I_B = 1/20000 (10V_2 + 151) sound reasonable? |
| hesperaux | gotta warn you - i'm about to play a game to end my night :) |
| hesperaux | that doesn't look all funky, so that could be right |
| hesperaux | why is it 151? wansn't it 150*whatever? |
| cne_ | hesperaux, the CCCS was 150 I_B |
| cne_ | so the nodal equation had I_B + 150 I_B + I_C = I_E |
| cne_ | basically i got a simple system, I_C + I_E = 1/1000 V_2 and then -I_C + I_E = 151/10000 since I_B = 100 uA |
| cne_ | which then gave 2I_E = 1/1000 V_2 + 151/10000 and then 2I_C = 1/1000 V_2 - 151/10000 |
| cne_ | hesperaux, my problem is |
| cne_ | that doesn't really remind me of how a BJT works |
| R0b0t1 | cne_, imagine lots of tiny particles. |
| R0b0t1 | You could call them electrons if you desire. |
| cne_ | i knew what bloch waves were before i could solve a basic circuit theory equation :-/ |
| Casper | man digikey shipment speed always amaze me |
| Casper | ordered stuff at 19:08 |
| Casper | 22:04: shipment confirmation: next day |
| Casper | so I will have my stuff for the week end! yay! |
| R0b0t1 | Casper: wat u git |
| cne_ | hesperaux, someone told me to ignore the CCCS |
| cne_ | does that sound legitimate to you |
| hesperaux | >_> |
| hesperaux | they might have said that because the CCCS will make sure IB is constantly the same as CCCS |
| hesperaux | 0001ACTION shrugs0001 |
| Casper | R0b0t1: mosfet, resistors, max232, ic sockets, 7805, 317, 18.432, 20pf, bc327/337, mosfet driver low/high side, mosfet driver low side, opamp, attiny85, cr2032 |
| Casper | and I'm sure this week end I'll say: crap I forgot this and that and that |
| cne_ | hesperaux, ooo |
| cne_ | yeah thats agood point |
| cne_ | but that would just mean I_B = 0 |
| hesperaux | =/ |
| cne_ | hesperaux, yeah that was it |
| cne_ | he said the CCCS ensures I_C = 150 I_B |
| cne_ | which makes sense |
| hesperaux | yeah |
| cne_ | hesperaux, Incidentally - as drawn this circuit has a fatal flaw: there is no return path for the base current.. Normally you would have a common ground between the left and right circuits, where the base current could return (and which would allow the emitter current to be 151IB. So really - as drawn, this circuit doesn't quite work.. |
| cne_ | normally IE=IB+IC but that is not quite possible in this configuration since there is no return path for the base current.. |
| hesperaux | yeah that's true |
| Evidlo | Ughhhhh I thought polyphasic sleep would be easier |
| Evidlo | Yesterday I would fall asleep during lecture for like 5 seconds at a time |
| Evidlo | and my handwriting started drifting |
| Casper | 0001ACTION needs to normalize all of his songs..0001 |
| Casper | this one is like at -10db :( |
| Viper-7 | thats what replaygain is for |
| Casper | atleast it's not set to +10.. |
| Casper | 0001ACTION needs to recall how to set them..0001 |
| Viper-7 | mp3 just needs a tiny chunk of extra header information of volume peaks & averages at certain frequencies, so we can reliably match each track's dynamic range to the playback equipment |
| Viper-7 | and thats kinda sorta mostly what replaingain is |
| ss23 | Does mp3 have that info already? |
| Casper | ss23: optional |
| Viper-7 | if you scan the entire track for it, sure |
| ss23 | I do hate it when listening to two albums with different nouse and you don't realise and BOOOOOM |
| Viper-7 | not as a header you can rely on |
| Viper-7 | its not like theres really a good excuse for modern mp3 players - pre-scanning the next track in the playlist should be a trivial affair |
| Casper | ss23: yeah.. you listen to some lenghty classic song.. which start and end quiet.. with a bit of loud in the middle.. then the next shuffle song is some metal.. |
| Viper-7 | instead we usually get standard dynamic range compression at best, aka a sliding window of a few seconds, not an offset and gain applied to the entire track |
