[02:04:08] <specing> Is it just me or has FT232HL price gone down?
[02:04:29] <specing> 4E @ mouser
[02:04:39] <specing> "Cut tape"
[02:04:54] <specing> Does cut tape mean you can actually order only one?
[02:05:01] <specing> I guess it does
[02:05:10] <mrfrenzy> yeah
[02:06:54] <specing> suddenly, 7E JTAG dongles ;)
[02:07:09] <specing> 480Mbit, that is
[02:08:09] <mrfrenzy> any idea where you could find a cheap lcd suited for a thermometer?
[02:08:16] <mrfrenzy> IE +/- and 3 digits
[02:09:59] <mrfrenzy> aah, should ofcourse ask capnkernel ;)
[02:10:08] <mrfrenzy> cause I can't find anything at digikey or farnell
[02:11:24] <specing> mrfrenzy: get a 8x2 COG
[02:11:30] <specing> they cost about 4E
[02:11:37] <mrfrenzy> too big and too expensive
[02:11:44] <mrfrenzy> you can buy a complete thermometer for $2
[02:11:45] <specing> well
[02:16:37] <mrfrenzy> 2 examples of cheap products with lcd
[02:16:39] <mrfrenzy> http://dx.com/p/digital-compact-lcd-thermometer-with-outdoors-remote-sensor-15553?item=240
[02:16:43] <mrfrenzy> http://dx.com/p/4-in-1-rotate-alarm-clock-with-digital-themometer-and-calendar-9823?item=494
[02:27:34] <specing> mrfrenzy: You're never going to get it nearly as cheap as the chinese can
[03:02:16] <mrfrenzy> specing: I know, but I would like to atleast pay about the same for the bare LCD as the chinese sell a complete product including shipping
[03:56:11] <Tom_itx> specing, cut tape means it comes on a pick and place spool from which they've cut the quantity you requested
[05:00:46] <mrfrenzy> CapnKernel: can you help me find an LCD for thermometer? Either 3 digits (possibly with +/-/max/min) or the cheapest graphical.
[05:03:49] <CapnKernel> I'll PM you
[08:11:05] <specing> Tom_itx: So that is the same as ordering one-by-one
[08:12:01] <Tom_itx> yup
[08:12:30] <Tom_itx> only you get the plastic wrapper with it
[08:16:24] <specing> Sweet! :)
[08:19:16] <Tom_itx> if it weren't for that ordering smt would be a real bummer. you get a big bill and open the box and have to search for what you ordered
[08:26:52] <specing> What is floor life, exactly?
[08:27:10] <specing> Floor Life (Out of Bag) At Factory Ambient
[08:27:11] <specing> (30?C / 60% Relative Humidity) (IPC/JEDEC J- STD-033A MSL Level 3
[08:27:25] <specing> * If devices are stored out of the packaging beyond this time limit the devices should be baked before
[08:27:28] <specing> use. The devices should be ramped up to a temperature of +125?C and baked for up to 17 hours.
[08:27:34] <Tom_itx> yes
[08:27:47] <Tom_itx> open to free air
[08:27:51] <Tom_itx> unsealed bag
[08:30:15] <specing> 168 Hours
[08:30:32] <Tom_itx> if you don't, you risk cracking the chip when it sweats off the moisture during the reflow process
[08:30:45] <specing> Ah
[08:30:51] <Tom_itx> i haven't worried about it much
[08:32:48] <Tom_itx> gotta go
[09:04:24] <rhumbot> hi all. im completely new to programmng microprocessors. i just tried to program an attiny13. i got Software Version = NULL.NULL; Hardware Version =NULL,NULL; and then Device code: 0x0a = (unknown). can i by any chance bribe someone in here to help me getting started?
[09:23:29] <DanFrederiksen> rhumbot, I use avrstudio to create .hex file and upload it to the chip with a programmer
[09:30:08] <rhumbot> DanFrederiksen downloading right now. thanks for the advice
[09:38:14] <DanFrederiksen> I actually found version 4 to be much better than 5. but both sort of work
[10:37:04] <karlp> anyone had any problems compiling with avr-libc 1.7 and gcc-avr 4.5?
[10:37:16] <karlp> my code was working fine with gcc 4.3 and libc 1.6.8,
[10:37:48] <karlp> but now I get errors like: http://pastebin.com/i0BXtkUQ
[10:37:58] <karlp> (compiling arduino core into a library to use with some other code)
[11:08:57] <karlp> http://arduino.cc/forum/index.php?topic=87186.0;wap2 is the answer, or enough of one...
[11:46:40] <rhumbot> hi all. im trying to program an attiny13 using avr studio. can i somehow connect to an avr910 programmer using avr studio?
[11:49:24] <Tom_itx> it probably won't support it
[11:49:36] <Tom_itx> if it's not genuine atmel it probably won't
[11:49:41] <Tom_itx> you can use avrdude
[12:08:35] <OndraSter> simple math: There are 10 questions out of 30 regarding databases. What is the probability that the first three out of four people pick Q about datahases and the fourth one about something else? Am I doing correctly 10/30 * 9/29 * 8/28 * 20/27? :)
[12:10:14] <rhumbot> quite right.
[12:10:44] <OndraSter> okay
[12:10:50] <OndraSter> because that is about 2.2%
[12:10:58] <OndraSter> but since this is databases with bad teacher, it actually has happened
[12:12:25] <rhumbot> Tom_itx when trying to connect using avrdude im getting Found programmer: Id = ""; type = x and Software Version = NULL.NULL :/
[12:14:47] <rhumbot> OndraSter its pretty much the same probability as any other combination of questions ... when flipping a coin - whats the probability of 10 times heads? the same as h-t-h-t-h ...
[12:14:48] <OndraSter> no, because on coin you have 50% chance of any state
[12:14:48] <OndraSter> here you do not
[12:14:50] <OndraSter> here the chances are not equal of having database q-not having database q
[12:16:16] <rhumbot> thats why i sais pretts much :)
[12:57:17] <jacekowski> OndraSter: it only means that on infinitely long run you will end up with ideal distribution
[12:57:24] * RikusW is thinking that a 74HC138 + 8x 4099B can make a nice 8bit to 64bit port expander...
[12:57:45] <jacekowski> OndraSter: on anything shorter you may end up with 100s of heads in the row
[16:00:16] * RikusW wonders is AT40K05 is still made
[16:51:29] <sirpistache> hi everyone
[16:51:31] <sirpistache> does LUFA supports XMEGA devices?
[16:56:41] <RikusW> think so
[17:02:44] <OndraSter> yes
[17:03:00] <OndraSter> abcmu spent days and nights on it :)
[17:59:10] <OndraSter> hmm I know why it didn't boot from floppy
[17:59:20] <OndraSter> arrrgh
[17:59:27] <OndraSter> THE DOS 6.22 FLOPPIES ARE IN DEUTSCH
[18:05:16] <ThersiT> what's the diff between dos 6.2 and 6.22?
[18:06:58] <ThersiT> I have some dos 6.2 install disks.. and 6.22 upgrade disks.
[18:10:25] <OndraSter> http://thepiratebay.se/torrent/6989294/MS-DOS_6.0_Source_Code_Leaked
[18:10:25] <OndraSter> holy
[18:10:26] <OndraSter> cow
[18:10:32] <OndraSter> it looks like real :o
[18:10:55] <OndraSter> I have DOS5.0 floppies :)
[18:11:01] <OndraSter> and win3.11 for workgroup floppies
[18:11:03] <OndraSter> original ofc
[18:21:47] <poptire> sirpistache: check out https://github.com/nonolith/USB-XMEGA
