[02:23:54] <Sgt_Lemming> anyone about?
[02:29:38] <ziph> Nope.
[02:30:32] <Landon> me me!
[03:44:58] <Roklobsta> nuh
[03:45:02] <Roklobsta> habing dinner

[04:46:00] <ibiwor> Hi
[04:47:20] <ibiwor> I'd like to know about AVR cam.. is it too slow for webcam integration to AVR chips for taking/sending pictures for image processing?
[08:39:05] <cyanide> CapnKernel, your stuff arrived today
[08:39:19] <cyanide> my family thanks you lol
[08:39:32] <cyanide> my workbench can be cleaned now
[08:40:52] <dirty_d> lol
[08:46:43] <CapnKernel> :-)
[08:47:13] <CapnKernel> cyanide: I hope they were the kind of boxes you had in mind.
[08:49:59] <dirty_d> damn, my quadcopter came out a lot heavier than i thought it would
[08:50:03] <dirty_d> i think its like 15 pounds
[08:50:07] <dirty_d> literally
[08:53:54] <dirty_d> http://i1186.photobucket.com/albums/z372/dirty_d2285/Quadcopter/quadcopter.jpg
[08:58:37] <cyanide> CapnKernel, they are perfect
[08:58:57] <cyanide> dirty_d, does it fly?
[08:59:26] <dirty_d> yea it hovers a little below 1/2 throttle
[09:01:39] <cyanide> https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/374437_395652223778165_100000001735491_1591687_1960027329_n.jpg
[09:01:41] <cyanide> :D
[09:02:50] <CapnKernel> What's the pic?
[09:03:04] <specing> cyanide: I can imagine the environmental friendliness of that thing
[09:03:26] <cyanide> im going to die in about 35-40 years
[09:03:33] <cyanide> why should i care what happens after that
[09:04:03] <specing> because you may have descendants?
[09:04:33] <cyanide> im sure the doctors and engineers of their generations will figure something out
[09:04:41] <Valen> i think that thing would hover at about half throttle too
[09:04:59] <cyanide> we got the internal combustion engine which is probably going to last maybe 1 more generation
[09:05:08] <Valen> but i think we all know http://www.popularmechanics.com/cars/jay-leno/4206704 is what you really want to be driving
[09:05:20] <Valen> The engine is a 30-liter V12
[09:05:26] <cyanide> keke
[09:05:34] <cyanide> you've seen the top gear episodes this season?
[09:05:43] <cyanide> they showed a 43 liter bmw v12
[09:06:07] <cyanide> some german guy took the engine from a ww2 fighter plane and built a car around it
[09:06:24] <cyanide> http://www.youtube.com/watch?v=RtKtwoqhJ6U
[09:06:42] <cyanide> 47 liter, my bad
[09:07:10] <cyanide> valvesprings and valve actuators outside the engine :D
[09:07:50] <dirty_d> wow
[09:07:57] <Valen> his car is ugly though
[09:08:01] <Valen> and a chain drive?
[09:08:15] <Valen> it lacks the sex appeal of lenos car
[09:08:51] <Valen> http://www.youtube.com/watch?v=DruAUxV9kaI&feature=related i'm glad i have a sub now lol
[09:08:58] <cyanide> leno's car probably required a budget 10 times that of this garage-built car
[09:09:08] <CapnKernel> My god, leaf springs
[09:09:13] <CapnKernel> And no hearing protection
[09:09:18] <cyanide> those engines will make you deaf
[09:09:19] <cyanide> for sure
[09:09:21] <dirty_d> lol
[09:09:39] <Valen> he still could have made it look better
[09:10:00] <CapnKernel> I think it's supposed to look... nasty.
[09:10:11] <Valen> it just looks crummy to me
[09:10:24] <Valen> nasty would have been easier
[09:10:31] <Valen> just take all the covers off the engine compartment
[09:10:32] <cyanide> http://www.streetfire.net/video/bmw-vs-brutus_2337839.htm
[09:10:33] <cyanide> hahaha
[09:10:37] <Valen> put some steel roll cage over it
[09:10:38] <Valen> done
[09:10:38] <cyanide> the startup sound is mad
[09:11:16] <Valen> oh yeah and ditch the damn chain drive
[09:11:34] <Valen> yeah he took some of the covers off for the top gear one, it looks better lol
[09:11:37] <cyanide> meh, i dont really like the car so much
[09:11:46] <cyanide> but this is just better than an electric car
[09:12:11] <Valen> more fun perhaps
[09:12:43] <cyanide> perhaps
[09:13:05] <cyanide> i like the tesla though
[09:13:22] <Valen> i think the car they make after the tesla will be good
[09:13:25] <Valen> A123 batteries
[09:13:30] <Valen> soooo much power
[09:14:09] <cyanide> so much power, he quit
[09:14:11] <cyanide> lol
[09:21:01] <dirty_d> id like a few thousand of those A123 cells
[09:39:06] <OndraSter> I'd like a few kilos of pure gold
[09:40:21] <CapnKernel> I'd like to hop into a bed pre-warmed by my missus
[09:41:01] <asteve> interesting
[09:46:53] <cyanide> id like to have a smoke
[09:46:54] <cyanide> brb
[11:07:38] <orated> Has anyone using KDevelop for coding avr programs?
[11:11:35] <Tom_itx> never heard of it orated
[11:15:12] <orated> Tom_itx: Which IDE do you use?
[11:15:35] <Tom_itx> i don't
[11:15:38] <Tom_itx> i use pn
[11:15:45] <orated> pn?
[11:15:47] <Tom_itx> and download the code with studio or avrdude
[11:15:51] <Tom_itx> programmers notepad
[11:15:56] <Tom_itx> comes with winavr
[11:16:19] <orated> Umm I'm on linux
[11:16:41] <specing> vim then
[11:16:54] <orated> vim, vi, gedit, kate is good
[11:17:11] <orated> but I was looking for something like Kdevelop as AVr studio is
[11:17:20] <Tom_itx> miss windows?
[11:17:51] <carp3> Eclipse ?
[11:17:59] <orated> Nope, I saw AVR Studio on friends system
[11:17:59] <Tom_itx> i seriously only use studio to download
[11:19:47] <orated> carp3: eclipse - Extensible Tool Platform and Java IDE
[11:20:12] <orated> I wish AVR Studio was available for AVR. It shows assembly code as well really good
[11:20:23] <orated> er for linux*
[11:20:36] <carp3> http://avr-eclipse.sf.net
[11:22:12] <orated> carp3: trying that ...
[11:22:14] <Tom_itx> i tried eclipse on arm and managed to crash it 2 or 3 times right off so i dumped it
[11:23:48] <carp3> also you can run avr studio using wine.
[11:27:13] <Sgt_Lemming> http://www.youtube.com/watch?v=ScSkthJct3w
[11:28:20] <Tom_itx> more progress since this morning?
[11:35:57] <Sgt_Lemming> yeah
[11:36:09] <Sgt_Lemming> three boards now, and got the ethernet module working
[11:36:24] <Tom_itx> what ether chip?
[11:36:26] <Tom_itx> the pic one?
[11:42:50] <Sgt_Lemming> Wiznet w5200, on a Wiz820io module
[11:42:59] <Sgt_Lemming> really nice little modules actually
[11:46:42] <specing> What is the advantage of wiznet w5200 over microchip ENC28j60?
[11:46:57] <specing> The only thing is that it has moar pins...
[11:47:50] <Sgt_Lemming> specing, hardware TCP/Ip stack for one
[11:48:34] <specing> Hmm sounds interesting
[11:53:36] <specing> Doesen't seem to be available on farnell
[12:38:13] <orated> carp3: Have you used kate?
[12:44:48] <carp3> no
[12:47:01] <orated> I guess simple gcc, gdb, make and such tools are sufficient instead of going for IDE
[13:45:30] <carp3> also you can run avr studio using wine.
[13:45:39] <carp3> OPS. sorry
[14:45:29] <konsgn> does anyone know about layout for usb circuits?
[14:45:40] <konsgn> i keep getting a lot of errors with mine
[14:46:29] <konsgn> I've tried multiple layouts but none are particularly reliable.
[14:47:11] <OndraSter> I always put the USB chip as close to the USB port as possible :)
[14:48:02] <konsgn> i did that, and kept the traces as short as possible and included the 22 ohm resistors
[14:49:23] <konsgn> is it possible that using the same atmega32u4 to test each of the designs is where the error lies? the chip seems to initiate communication properly, but sending data fails
[14:57:28] <Tom_itx> dip or tqfp?
[14:57:43] <OndraSter> there is DIP one at all?
[14:57:50] <Tom_itx> i don't think on the U4
[14:59:09] <Tom_itx> there is a fomula for figuring the resistors depending on the trace impedance
[14:59:18] <Tom_itx> i used 27 on mine
[14:59:38] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/boards/atmega32u4/atmega32u4_1.jpg
[14:59:43] <Tom_itx> that one seems to work fine
[15:00:14] <konsgn> tqfp
[15:00:53] <konsgn> how do you determine trace impedance? besides, my traces are at most 200 mil
[15:00:56] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/boards/USBTiny_Mkii/USBTinyMkII_1-1c_top.jpg
[15:01:13] <Tom_itx> that's another usb layout
[15:01:13] <Tom_itx> it also works fine
[15:01:35] <OndraSter> 200mil ?!
[15:02:00] <Steffanx> 2000
[15:02:22] <Tom_itx> 1000 is one inch
[15:02:25] <Tom_itx> so about a quarter inch
[15:02:30] <Tom_itx> settle down
[15:02:31] <konsgn> nope i mean 250 mil
[15:02:37] <specing> I just found linkinstruments.com
[15:02:42] <konsgn> about 6mm
[15:02:50] <OndraSter> for DM and DP lines?
[15:02:51] <specing> Too bad they don't have Linux support
[15:02:57] <cyanide> 250mil?
[15:02:57] <Steffanx> I just clicked on that link specing
[15:02:58] <cyanide> pics?
[15:03:03] <konsgn> yup 22ohm resistor included
[15:03:18] <OndraSter> my USB lines were 10 or 12 mil :)
[15:03:29] <Tom_itx> and mine use those supressors
[15:03:39] <cyanide> i keep mine 16 mil. all of them
[15:03:45] <specing> No linux support = one customer less. (me)
[15:03:48] <Steffanx> And me specing
[15:03:49] <OndraSter> I don't have any resistors
[15:03:50] <Steffanx> and me
[15:04:38] <konsgn> so is it better to use thicked lines? i used 10mil
[15:04:56] <Steffanx> 10mil is ok
[15:05:07] <konsgn> Tom_itx I cant load any of those site for some reason
[15:05:19] <Tom_itx> you have port 81 blocked
[15:05:35] <Tom_itx> and my isp won't let me use 80
[15:05:51] <Landon> ((they're also really slow right now)
[15:06:00] <cyanide> how would him having port 81 blocked have anything to do with your isp?
[15:06:03] <Steffanx> Yep
[15:06:05] <Tom_itx> i can fix the slow
[15:06:07] <Tom_itx> hang on
[15:06:10] <Steffanx> You should reboot your server everyday :P
[15:06:13] <cyanide> your website is slow, nothing else
[15:06:15] <Steffanx> *every hour
[15:06:21] <Tom_itx> or get a new router
[15:06:22] <OndraSter> and three times in a row!
[15:06:37] <Tom_itx> i tried to set up a linux box as a router but haven't finished it
[15:06:54] <Tom_itx> hang on...
[15:07:09] <Landon> I just let my VPS handle all of the nonsense, I've gone through too many connections with too many restrictions over the past 5 years
[15:07:39] <cyanide> Tom_itx, those leds on your avrispmk2 board are 0805 or 0603?
[15:10:21] <Tom_itx> that should fix the slow
[15:10:30] <Landon> indeed
[15:10:30] <cyanide> also, Tom_itx you have a part number for that crystal?
[15:10:36] <Tom_itx> yes
[15:10:45] <Tom_itx> it's an abm8 package
[15:10:48] <cyanide> ok
[15:10:53] <cyanide> no caps?
[15:11:01] <Tom_itx> 8pf
[15:11:19] <Tom_itx> i switched to a resonator though
[15:11:23] <Tom_itx> you can look at both
[15:12:27] <cyanide> im talking about the one on the usbtiny mk2
[15:12:31] <cyanide> http://tom-itx.dyndns.org:81/~webpage/boards/USBTiny_Mkii/USBTinyMkII_1-1c_top.jpg
[15:12:36] <Tom_itx> http://search.digikey.com/us/en/products/CSTCE16M0V53-R0/490-1198-1-ND/584635
[15:12:44] <Tom_itx> that's the resonator on it
[15:12:54] <cyanide> cool, thanks!
[15:13:21] <Tom_itx> http://search.digikey.com/us/en/products/NX3225SA-16.000000MHZ/644-1049-1-ND/1128921
[15:13:23] <Tom_itx> and the crystal
[15:13:50] <Tom_itx> btw, mouser is cheaper
[15:15:39] <cyanide> yeah, almost always
[15:17:18] <OndraSter> what is the advantage of resonator over crystal? :)
[15:17:28] <mrfrenzy> price
[15:17:33] <OndraSter> ah
[15:17:51] <Kevin`> I would consider the second one to be an oscillator, not a crystal
[15:18:27] <Kevin`> unless it's just a weirdly packaged crystal
[15:18:29] <Tom_itx> it's pretty accurate
[15:18:36] <Tom_itx> yep it's a crystal
[15:19:01] <Kevin`> normally those 4-pin devices are something like power, -power, clock out, enable-or-vin
[15:19:11] <Tom_itx> 15ppm tolerance and stability
[15:19:23] <Tom_itx> the extra 2 are nc
[15:19:26] <Tom_itx> or gnd
[15:19:30] <Tom_itx> i gnd'd them
[15:23:57] <Tom_itx> Kevin`, at the time i was looking for a tiny crystal
[15:24:05] <Tom_itx> it's the best i could come up with
[15:24:15] <Tom_itx> until i found the resonator which works just fine
[15:29:28] <cyanide> you have the eagle part for that resonator?
[15:31:51] <Tom_itx> yup
[15:34:10] <Tom_itx> i'll get it in a little while
[15:53:32] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/eagle/Murata_resonator.lbr
[15:57:34] <cyanide> thanks!
[15:58:42] <dirty_d> cyanide, hows your thing coming?
[15:59:03] <cyanide> coming along slowly
[15:59:15] <cyanide> i scored some free xmega samples from atmel india
[15:59:21] <cyanide> they're on the way
[15:59:21] <dirty_d> did you get your stuff in the mail?
[15:59:25] <dirty_d> wow
[15:59:30] <dirty_d> i didnt think anybody ever got samples
[15:59:34] <cyanide> :)
[15:59:40] <dirty_d> the 32a4u ones?
[15:59:41] <cyanide> i just emailed them directly
[15:59:47] <cyanide> yes, 32a4u and 64a4u
[15:59:50] <dirty_d> cool
[16:00:00] <cyanide> if they have the 64a4u, that is. don't know for sur
[16:00:02] <cyanide> sure*
[16:00:16] <dirty_d> 32k is plenty for that thing youre building
[16:00:36] <dirty_d> you will probably use 4 - 8 id think
[16:02:19] <cyanide> yeah probably. i just told them i needed some xmega_a4u samples. they told me they'd send some if they had any. then emailed me saying they sent a couple, either both 32a4u or 1 x 64a4u + 1 x 32a4u
[16:02:24] <cyanide> aww he left
[16:03:14] <Kevin`> aww, I wanted to ask of those were lead-acid batteries on his helicopter
[16:03:42] <Tom_itx> would be kinda heavy for a helicopter
[16:03:46] <Tom_itx> i'd think
[16:03:54] <Tom_itx> i didn't see it though
[16:03:57] <Kevin`> well where's the 15 pounds coming from ;p
[16:04:05] <Tom_itx> true
[16:04:06] <Kevin`> http://i1186.photobucket.com/albums/z372/dirty_d2285/Quadcopter/quadcopter.jpg
[16:04:36] <Tom_itx> they look like the ones i put on my bot
[16:04:45] <Tom_itx> and come to think of it i'm pretty sure they are
[16:05:36] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/maxbot/image013.jpg
[16:05:47] <Tom_itx> 6v each
[16:05:54] <Tom_itx> 7Ah? i forget
[16:09:49] <mog> inflex, did you ever get around to that code?
[17:50:02] <inflex> sort of - just haven't finished it; figured you'd not have the LCD panels yet :)
[18:04:56] <OndraSter> http://cz.mouser.com/ProductDetail/NXP-Semiconductors/74LVCH162245ADL11/?qs=sGAEpiMZZMvKM5ialpXrmsCo9kQ8AJh%2f
[18:05:09] <OndraSter> 16bit bidirectional buffer for .37€?
[18:05:10] <OndraSter> wow
[18:05:18] <OndraSter> regular HC244 costs more
[18:05:21] <OndraSter> for 8bits :)
[18:05:29] <OndraSter> single direction!
[18:09:41] <OndraSter> http://i.imgur.com/kxEPf.jpg
[18:09:42] <OndraSter> <3
[18:21:21] <vectory> china quality ^^
[20:12:19] <brentbxr^t_> ok
[20:52:25] <dirty_d> wtf
[20:52:43] <Tom_itx> bbq
[20:54:03] <dirty_d> chea
[22:45:27] <Casper> rue_house: I got my refund for the map gas canister
[22:45:57] <Casper> but it wasn't easy... lots of work for the few bucks...
[22:48:24] <rue_house> hmm
[22:48:49] <rue_house> know how I can make a bluetooth device under linux that would supply an internet connection to my iphone?
[22:48:53] <rue_house> should be possable
[22:58:41] <Casper> should yes, but no idea how
[22:58:58] <Casper> your iphone don't have wifi?
[23:23:51] <atarax> hi, have any of you done anything with qtouch
[23:34:20] <Casper> does q-tips do the same things? :D
[23:34:27] <Casper> (in other words, not me)
[23:35:13] <atarax> it's the library to put touch sensors on an avr
