[00:07:28] <UnKnOwN|> lsusb and dmesg output if it helps: http://pastebin.com/inPNwVnb
[00:20:16] <rue_mohr2> UnKnOwN|, what have you tried?
[00:20:21] <rue_mohr2> what does ipconfig -a show?
[00:25:27] <Casper> UnKnOwN|: wifi is more complex than wired
[00:25:52] <Casper> you need not only the module (driver) but also you need the wpa_supplecant or whatever it's spelled
[00:25:55] <Casper> you also need iwconfig
[00:32:46] <rue_mohr2> there is a nice howto if you google for it
[00:32:50] <rue_mohr2> I used it once, it worked
[00:37:17] <evil_dan2wik> Casper, the Yun has built in Wifi, He wants to use a Wifi USB, which means that most of it should already be there.
[00:40:17] <Casper> ok
[02:44:52] <rue_house> it DID detect as wlan0 tho
[02:55:43] <evil_dan2wik> rue_house, what are you refering to?
[02:56:02] <evil_dan2wik> The arduino Yun has built in Wifi on wlan0
[06:38:29] <Lambda_Aurigae> http://xkcd.com/1406/ someone make me one!
[07:13:52] <Fleck> Lambda_Aurigae: S-video to diesel would be fun! :D
[07:25:48] <CoolBear> I want two! Take my money!
[07:35:17] <Fleck> is it ok to add diode at op-amps output?
[07:42:13] <CoolBear> In what configuration? I know some fuzz/distortion guitar boxes use that to clip the signal.
[07:45:38] <twnqx> let's just say if you don't need the range of the diode threshold you might be ok...
[07:46:07] <twnqx> and can live with the resulting voltage shift (assuming you put in inline)
[08:07:45] <Fleck> twnqx, CoolBear: its LOW side current sense, ADC shows some values at idle, adding diode helps a bit
[08:13:00] <CoolBear> I'm actually doing a project with high-side current sensing atm.
[08:35:39] <rue_house> I dont suggest those little modules on ebay
[08:35:47] <rue_house> more noise than signal
[08:42:56] <CoolBear> I'm just doing farely simple resistive sensing plus ompamp into a comparator that cuts the charge cycle.
[08:49:38] <Fleck> rue_house: it's not, I am making my own... kind of
[09:55:16] <phinxy> Im having issues with my voltage regulator overheating on my motherboard. How would you microchip guys add a heatsink to this? http://www.asus.com/websites/global/products/UjihzQKhBmQmiVsY/digi.jpg
[09:55:56] <NooM> hm, buy a mainboard where allready is a heatsink :D
[09:56:12] <CoolBear> Thermal adhesive
[09:56:41] <NooM> true, there are even some ram heatsinks with adhesive on them (gpu ram)
[09:57:14] <CoolBear> Just find a heatsink that fits and doesn't bump into anything else.
[09:57:52] <CoolBear> Do note that some thermal adhesive is for permanent placement, which basically means you'll rip the chip off if you try to remove it.
[09:58:54] <phinxy> CoolBear, yeah i would like something similar that GPU's have. A heatsink with sticky tape on it
[09:59:18] <NooM> but.. honestly if it overheats, something else is wrong
[09:59:22] <NooM> it should do that
[09:59:46] <phinxy> NooM ive done my research :)
[09:59:50] <NooM> get some fans for your case
[10:00:39] <CoolBear> Don't get the fans that scream when you show up, they are just annoying. Then they start crying and all hell is loose.
[10:00:50] <NooM> lol
[10:01:13] <specing> phinxy: design error? Warranty replacement?
[10:02:00] <specing> That chip shouldn't heat up at all
[10:02:03] <phinxy> specing, well the motherboards is a B85M-G, they arent built for high voltages but with latests BIOS its unlocked for some reason
[10:02:05] <specing> its just PWM
[10:02:19] <specing> warranty
[10:03:01] <phinxy> specing that might be true. But what is VRM thermal throttling then?
[10:03:14] <NooM> the mosfets create the heat
[10:03:22] <NooM> the things around that chip
[10:03:36] <phinxy> NooM, that already have heatsinks on them im guessing
[10:03:48] <NooM> yeah the golden one
[10:10:11] <phinxy> NooM, that isnt a mosfet. Its the chipset
[10:10:15] <phinxy> IntelĀ® B85 Chipset (IntelĀ® DH82B85 PCH)
[10:10:24] <phinxy> seems like all mosfets are without heatsinks
[10:11:02] <phinxy> The mosfets: http://www.yume-akari.com/Review/Asus%20B85-G/14.jpg
[10:11:18] <phinxy> orange
[10:11:43] <NooM> yeah, on his img there was a gold heatsink on them
[10:13:07] <phinxy> NooM, no that heatsink is over:http://www.yume-akari.com/Review/Asus%20B85-G/26.jpg
[10:13:13] <Getty> i really need to find a better logic for the light=>tweet algo.... https://twitter.com/GettysRoom
[10:17:20] <phinxy> What should i search for on ebay to find small heatsinks for chips?
[10:17:36] <NooM> gpu ram heatsink
[10:29:44] <rewolff1> or search for "heatsink a4988 10" (for $1 you get one, for $2 you get ten).
[10:30:43] <rewolff1> Or just search for "heatsink", sort by price, and you'll find an ad for "with adhesive" on the first page or two.
[10:34:14] <phinxy> Yeah i found a couple. Do i want as large 'fins' as possible? copper or aluminum?
[10:34:49] <CoolBear> You want as much surface area as possible.
[10:35:03] <CoolBear> That can mean many fins.
[10:36:08] <CoolBear> I seem to recall something(do not take this as confirmed fact) about copper beeing able to hold more heat, but alu is better at radiating it away. But honestly, any will do.
[12:48:44] <carp3> Hi, is it possible to use ATMEGA8A's PWM as 16bit dac ?
[12:54:14] <Casper> yes, no, maybe
[12:55:37] <Casper> yes, it can work with RC filter. No/maybe, due to the noise it won't give you 16 bits accuracy, but should be more than the 8 bits... and the RC also limit the speed
[18:38:43] <N1njaneer> Robin Williams died. :(
[18:38:53] <Lambda_Aurigae> yup.
[18:38:57] <Lambda_Aurigae> possible suicide
[18:39:07] <N1njaneer> So sad
[18:39:09] <Lambda_Aurigae> nanu nanu
[18:47:28] <N1njaneer> Guess no Mrs Doubtfire 2 now.
[18:49:14] <Lambda_Aurigae> guess not.
[18:49:22] <Lambda_Aurigae> and no Return from Ork either.
[19:57:31] <N1njaneer> #AVR is so quiet again!
[20:03:03] * Lambda_Aurigae screams
