[03:47:05] <malinus> thekindlyone, the easiest thing is to use the arduino one. It should only be a couple of minutes of work. It souldn't depend on much other arduino-code.
[03:47:19] <malinus> minutes/hours ;)
[04:23:18] <vsync> yes and you can power arduino straight with 110/220v ac. It's so damn easy. what you want to do is, "live" goes to "gnd" on arduino
[04:23:35] <vsync> must i continue? It's child's play really
[04:25:11] <vsync> you just have to modify the bootloader to engage the AC-Drive
[04:35:32] <malinus> vsync, no need to act like that, what I said was in comparison to using time learning asm.
[04:37:36] <vsync> if you do ac, you can use python
[04:38:00] <vsync> sounds like a long shot yeah but totally true
[04:41:44] <malinus> what's with this guy
[04:42:18] <vsync> now what?
[07:31:53] <Jartza> whoa
[07:32:14] <Jartza> 19€ laminator, 10€ clothes iron -> little fiddling -> perfect pcb laminator :)
[07:35:00] <Jartza> took the adjustable thermostat out from the clothes iron and replaced the thermostat in laminator with that
[07:35:12] <Jartza> now I have adjustable laminator for less tan 30€ :)
[08:30:26] <Lambda_Aurigae> I use a sharp fuser for a pcb laminator.
[08:37:28] <rue_house> what temp?
[08:39:40] <Lambda_Aurigae> I run it at about 150degF for press-n-peel blue
[08:42:21] <Lambda_Aurigae> over 200degF for other toner transfer, like using magazine paper.
[08:57:10] <twnqx> what exactly is "laminating" in this context?
[08:57:21] <twnqx> (not that i am still making PCBs myself, but...)
[10:21:08] <Lambda_Aurigae> hmm..those should be degC, not degF
[10:38:34] <vsync> can you program it with python? does it have twitter
[10:38:38] <vsync> if no - it's completely useless
[10:45:37] <Tom_itx> Lambda_Aurigae, i had to move again
[10:45:45] <Tom_itx> ms took down no-ip
[10:46:06] <Tom_itx> bastarts
[10:47:28] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/index.php
[10:47:32] <Tom_itx> for now
[10:49:38] <specing> took a while for you to notice it ;P
[10:49:45] <specing> Also you need to fix topic
[10:49:50] <specing> And get a real domain name
[10:52:45] Tom_itx changed topic of #avr to: http://www.avrbeginners.net http://tom-itx.ddns01.com:81/~webpage/index.php http://www.avrfreaks.net ENCOURAGE PEOPLE OR WE WILL SQUASH YOU, REALLY!
[10:57:14] <Tom_itx> i noticed right away.. they sent me an email
[10:57:17] <Tom_itx> i'm just lazy
[10:58:11] <specing> lol
[11:01:43] <Lambda_Aurigae> Tom_itx, might want to update the channel topic.
[11:01:53] <Lambda_Aurigae> I've tried to point several people at it over the last few days.
[11:02:13] <Lambda_Aurigae> oh,
[11:02:16] <Lambda_Aurigae> nevermind..there is
[11:02:18] <Lambda_Aurigae> there it is.
[11:02:22] <Lambda_Aurigae> I'm slow today.
[11:02:28] <Lambda_Aurigae> been out cutting and moving down trees.
[11:06:32] <Lambda_Aurigae> did get a neighbor with his big tractor and front loader with gripper to move trees for us though.
[11:42:57] <Lambda_Aurigae> http://home.bethnray.com/tractor/
[11:43:01] <Lambda_Aurigae> pics of da tractor
[12:03:43] <Lambda_Aurigae> http://dilbert.com/
[12:03:47] <Lambda_Aurigae> today's dilbert is awesome.
[12:21:55] <vsync> Is this somesort of a fusion of urban idiots in a hillbilly US town, so that a tractor becomes a point of interest, a sight?
[12:27:36] <Lambda_Aurigae> hehe.
[12:27:38] <Lambda_Aurigae> probably.
[12:27:56] <Lambda_Aurigae> specially when he saved me about 4 days work.
[12:30:11] <vsync> now the pictures can go on the mantlepiece
[12:30:16] <vsync> all hail tractor
[12:30:19] <Lambda_Aurigae> yup.
[12:30:26] <Lambda_Aurigae> all hail Royal Young and his tractor.
[12:31:07] <Lambda_Aurigae> I lost 6 trees in my yard.
[12:31:40] <Lambda_Aurigae> 5 of them are rather rare, existing no place else in Iowa, and no place else west of the mississippi far as I know.
[12:33:46] <Lambda_Aurigae> the arboretum guys were out to look at them last year and were very interested...I wish they had just transplanted the dang things...hard wood but brittle. Kentucky Dwarf Coffeetrees.
[12:35:10] <vsync> in iowa, even the trees are inbred
[12:35:19] <Lambda_Aurigae> dang things are interrupting my electronics play!
[12:35:21] <vsync> hence the rarity
[12:35:48] <Lambda_Aurigae> but we have great corn and cows!
[12:36:14] <vsync> ...not saying you don't
[14:43:58] <Timmy> datasheet says it is only allowed to write about 100,000 times on EEPROM. does it matter how big the data that is going to be written on that is? a mean does it makes difference between writting a word and a float?
[14:46:35] <learath> they generally mean 100,000 times per cell written
[14:46:39] <learath> I don't know how big the cells are
[14:49:41] <Timmy> right...
[14:49:46] <Timmy> learath: tnx
[14:53:35] <Timmy> how can I findout how much memory my application will occupy at SRAM while is running in the uC?
[15:02:22] <Timmy> If I set any initial value for eeprom variables while I am declaring them, will this replace the stored values after a reset?
[15:37:15] <Lambda_Aurigae> Timmy, simulate it to find out how much it will use...
[15:37:43] <Lambda_Aurigae> there is a profiler that will tell you how much is used on setup but won't tell you things like stack usage...you kinda gotta guess at that.
[15:38:08] <Lambda_Aurigae> as for eeprom stuff, I believe you have to force a write back to the eeprom locations.
[15:41:28] <Lambda_Aurigae> avr-size is the program that tells you the size of things.
[17:28:08] <Jartza> hmmh
[17:28:26] <Jartza> maybe a bit too much heat on the laminator ;)
[17:41:26] <ColdKeyboard> On logic analyzer I get something like this http://i.imgur.com/dUT8uIi.png but I don't see any characters on HD44780... Can anyone tell me what am I doing wrong? :\
[17:45:12] <Tom_itx> is the backlight on?
[17:45:32] <Tom_itx> and why aren't you using fleury's lcd lib?
[17:46:43] <ColdKeyboard> I have A and K connected to VCC and GND trough 1K resistor so I can see the blue backlight but no chars on display...
[17:47:03] <ColdKeyboard> D0 trough D4 should be grounded and D5 trough D7 should be connected to data pins, right?
[17:47:27] <Tom_itx> leave D0..4 open
[17:47:32] <ColdKeyboard> And also I have VSS, VDD and VO pins, what is Vo for? Letter brightness?
[17:47:45] <Tom_itx> what pin is it?
[17:47:48] <Tom_itx> 3 is contrast
[17:47:52] <ColdKeyboard> 3rd from right
[17:47:57] <ColdKeyboard> It goes VSS, VDD, VO
[17:48:25] <Tom_itx> is it blue with white letters?
[17:48:29] <Tom_itx> i've got 2 of those...
[17:48:53] <ColdKeyboard> It goes VSS, VDD, VO, RS, WR, E, D0...
[17:49:05] <Tom_itx> you should have 7 pins wired beside the V & G pins
[17:49:08] <ColdKeyboard> Blue backlight, for letters I dont know since I don't see any, I guess they are white :)
[17:49:27] <Tom_itx> RS, RW, E, D4..7
[17:50:05] <Tom_itx> pretty sure you need to GND E
[17:50:10] <Tom_itx> but it's been a while...
[18:02:52] <Lambda_Aurigae> E is used to signal high nibble or low nibble..it's toggling a lot more than it should.
