00:11 rue_house yay, now I can stay in and code
00:18 rue_house !time
00:18 tobbor My watch says its 22:12 Tue Dec 27 2011
01:04 rue_house my editor has had to many incomplete rewrites that I'm now at the point where the design has become ambigious
01:04 rue_house theres documentation of 3 systems, none of which are reflected in the last written code
01:04 theBear poor rue and his ambiguous article
01:04 theBear i say man-it-up at the final edit :)
01:05 rue_house I'm throwing alot away this rewrite
01:05 rue_house right now I'm trying to work out what happened to the code that used to work out what text to draw for the windows current x,y scroll location
01:05 rue_house it looks like its not anywhere anymore
01:06 rue_house I'v got an object called a navigator which I think is supposed to do it, but the code is the copy of another object thats obsolete
01:07 rue_house erp, I think I just found it by antoher name
01:08 theBear yeah ? well if it makes yer feel better i rebuilt a laptop fan right down to cleaning and repacking some little roughly 3mm o/dia ball bearings thismorning, and on the final test before reassembly my STUPID scratchy-pot-lm317k bench supply smoked the little tiny 10 pin everything-ic :( i been looking/thinking all day between other little things what to do, grab a bigger one out of a big ugly fan and hack up the case ? grab a tiny one from a tiny
01:08 theBear fan and bypass the output ? grab a tiny one from a mid size fan and cross my fingers ? even grab one of the VERY simple single-component dual-transistor/hall flip flop things some of the dead ones i've got had and hack that in, losing all the nice sensing and stuff... oooh... maybe the sense output is looped off the hall in this one, rather than thru the controller ic
01:09 rue_house lm1317?
01:10 rue_house I just replaced one in my bench supply, but when I was done, it possibly turned out to be a broken wire
01:10 theBear 337k, to3 adjustable 3pin reg
01:10 theBear hehe
01:10 rue_house ah
01:10 rue_house 10 pin everything ic?
01:10 rue_house lm1317?
01:10 theBear point is, the worlds tiniest laptop fan shouldn't have wasted my whole day, and naturally the laptop is in a million pieces over the bench 'cos the fan is the last component to remove under EVERYTHING else
01:10 theBear oh, it's a bit cooked but i look
01:10 rue_house if you need I have a few
01:14 theBear damn it's hard to tell.... i had a couple drinks, and it's one of those REALLY stupid off-grey ones that you can only even notice on a funny angle in a bright light, and the whole middle is cooked and bulged :(
01:14 rue_house is it a radioshack 24V 1A supply with variable current and voltage settings?
01:14 rue_house micronta something
01:15 rue_house metal case, everything is F************(&*&^*%^ riveted togethor?
01:15 theBear maybe 2.5mm^2 tiny smd ...looks like directly drives the two half-coils (rated whole fan 5v/.5a) and gets a little feedback via two resistors and a shared sense line, and err, SOMETHING like the 4pin hall going into it on at least 2 pins, with pullup or downs somewhere in the mix
01:17 theBear no, it's the first little metal 2* U project case i found lying around my stack of bits when i needed a tiny psu in a big hurry, as i recall it was adjustable constant current for charging old phone batteries and gel cells at the time, but these days it's a maybe ooh, 1.5A sustained at most voltages from around dropout (1.2v?) up to somewhere near 20v
01:17 theBear gets a bit warm in the middle tho :)
01:18 theBear apart from the 'scratchy' pot (drops out and jumps around 3.5-4.2v area, not great for 5v tiny fans it seems) it's a nice solid little supply, even the dodgy silicone-not-mica washer on the external case mounted to-3 hasn't busted yet
01:21 theBear hmm... in general that style of dumb-control for a 2phase little fan should be fairly similar speed on a given fan regardless of controller right ? it's all about coil-power-per-push and air resistance and hall position i would think ?
01:38 rue_house ah
01:38 rue_house cant help there
01:51 rue_house ah, I went waaay back in my code and found the origional hitch, colour
01:52 rue_house when I started to make the systems to add colour, everything gradually went left
02:21 Geneva_Mode Hello again! :)
02:22 Geneva_Mode Anyone here?
02:24 rue_house y
02:24 Geneva_Mode Hello! It's nice to meet you.
02:24 Geneva_Mode I had a question about Arduino boards.
02:25 rue_house ok
02:25 Geneva_Mode When programming for the Arduino, is it possible to compile the program so your robot doesn't need to be plugged in to run the code?
02:25 rue_house the programs always run right on the arduino,k do you mean for controlling it?
02:25 Geneva_Mode By "plugged in", I mean via USB to the computer.
02:25 Geneva_Mode Yes.
02:26 rue_house if you make soemthing else to control it, yes
02:26 rue_house use 4 iputs to make a joystick to control it
02:26 Geneva_Mode Can I 'save' commands to the Arduino so that it doesn't have to be plugged into my computer for the robot to use it?
02:27 rue_house thats how it works
02:27 Geneva_Mode Oh, cool!
02:27 Geneva_Mode I've been thinking about getting into robotics.
02:27 rue_house your program is sent to the arduino and runs there
02:27 rue_house cool
02:27 Geneva_Mode But I don't have the space to do it. :(
02:28 rue_house do you have a little robot now?
02:28 Geneva_Mode No.
02:28 rue_house do you have an arduino?
02:28 Geneva_Mode I've yet to make my first robot, ever.
02:28 Geneva_Mode No.
02:28 rue_house ok
02:28 Geneva_Mode No parts, no anything. Still book-learning.
02:28 rue_house do yo uhave a plan?
02:28 Geneva_Mode What do you mean?
02:29 rue_house did you want to make something from scratch or buy a robot kit?
02:29 Geneva_Mode I'd like to make something from scratch.
02:29 Geneva_Mode I'd like to make my robots mostly out of wood.
02:29 rue_house I dont like wood for robots, but whatever :)
02:29 Geneva_Mode What are your reasons for not liking wood, if I may ask?
02:29 rue_house do you have any money saved up to get an arduino?
02:30 Geneva_Mode Not yet. I'm still in the 'reading' phase.
02:30 rue_house wood, cardboard, and hot glue have caused me a lot of problems when I started
02:30 Geneva_Mode What kind of problems?
02:30 rue_house have you ever programmed in C
02:30 Geneva_Mode I've programmed C++
02:30 Geneva_Mode And even made a semi-working breakout game with the Win32 library.
02:30 rue_house problems like melting or splitting or warping or generally falling alart
02:30 rue_house ok
02:31 Geneva_Mode Can't you just cut cardboard with a pen knife?
02:31 rue_house yes, its not good structural material tho
02:31 rue_house better is "corriplast" its like cardboard but its plastic, signs are made from it
02:31 Geneva_Mode Would hard wood, something like mahogany, be good for a supportive base?
02:32 Geneva_Mode I find plastic a nice material (although I've only worked with it twice during school), but I'm one of those eco-mania types.
02:32 rue_house I avoid wood and cardboard..
02:32 Geneva_Mode Who wants to make the most environmentally friendly stuff possible.
02:32 rue_house inste3ad of a peice of mahogony, you can get a cutting board from a dollar store
02:32 Geneva_Mode So I plan to avoid plastic and oil products as much as I can.
02:33 Geneva_Mode A cutting board, like plywood?
02:33 rue_house ok
02:33 rue_house well, like nylon
02:33 Geneva_Mode Do you have any pictures or videos of robots you've made yourself?
02:33 rue_house maybe we should leave our differences here
02:33 rue_house http://eds.dyndns.org/~ircjunk/robots/robots2.html
02:33 Geneva_Mode I'm not trying to be argumentative, just to clear that up. I was legitimately asking out of curiosity.
02:34 rue_house http://eds.dyndns.org/~ircjunk/robots/robot_family2.jpg
02:34 Geneva_Mode That second robot's nice.
02:35 rue_house hmm the list is out of date now...
02:35 rue_house there are 3 more arms
02:35 Geneva_Mode What kind of feelings arise when you're making or designing robots?
02:36 rue_house depends if I finished them and get to sit back and watch them :)
02:36 Geneva_Mode What do you feel when you do that?
02:36 rue_house its a dynamic challange, it goes right along with gaming
02:36 Geneva_Mode Playing games or making them?
02:37 rue_house what people get from playing games I get from making robots
02:37 Geneva_Mode A feeling of accomplishment?
02:37 rue_house sure
02:37 Geneva_Mode I myself would probably be really proud of making my first robot.
02:37 rue_house theres alot of defeat and triumph along the way
02:38 Geneva_Mode Can you name some of the defeats?
02:38 rue_house !assist robots/flatbot/
02:38 tobbor Possibly http://eds.dyndns.org/~ircjunk/robots/flatbot/
02:38 rue_house may I suggest making something like that
02:38 Geneva_Mode That would probably be one of my first designs.
02:39 rue_house that about $25 in parts
02:39 Geneva_Mode Basic R/C 2-wheeler.
02:39 Geneva_Mode Where do you get your motors, and electrical stuff?
02:39 rue_house from my shop :)
02:39 Geneva_Mode What shop is that?
02:39 rue_house I strip down everything I can find
02:39 rue_house http://eds.dyndns.org/~ircjunk/robots/buddy_III/p1020055.jpg
02:40 rue_house http://eds.dyndns.org/~ircjunk/robots/arm5/p1020977.jpg <-- wish I could see that much of my bench, right now there's an arm bolted to it
02:41 rue_house Geneva_Mode, so if I may ask, how did you find this chat channel?
02:41 Geneva_Mode Just searched for 'robotics' on NetSplit.
02:41 rue_house hmm
02:41 rue_house what country are yo uin?
02:41 Geneva_Mode I'm in England.
02:42 rue_house hmm lots of people from odd places latley
02:42 rue_house we get a lot of usa, not much canada, lots of australlia
02:42 Geneva_Mode Crumpets?
02:42 rue_house <-- canada
02:42 Geneva_Mode Cool. :)
02:43 rue_house haha
02:43 rue_house oh it dosn't work
02:43 Geneva_Mode Are you familiar with a book titled 'Robot Builder's Bonanza'?
02:43 rue_house thought I could make a canadian flag in ascii, didnt' work, hah
02:43 rue_house Geneva_Mode, I have that book, yes
02:43 Geneva_Mode Awesome!
02:44 Geneva_Mode I got it for Christmas!
02:44 rue_house it looks great, but after experiance I can tell ya the stuff dosn't work as well as it looks like it does
02:44 rue_house haha
02:44 rue_house k, its good for quite a bit of basics
02:44 rue_house if you just got it, I suspect you have a newer version than mine!
02:44 Geneva_Mode Is it one of those books that oversimplifies a little bit just to make liftoff easier?
02:44 Geneva_Mode Fourth edition.
02:45 rue_house mines prolly first
02:45 Geneva_Mode If it isn't too personal, how old are you?
02:45 rue_house 153 :)
02:45 Geneva_Mode That's quite an age. :)
02:46 rue_house indubadly
02:46 Geneva_Mode I'm eighteen.
02:46 rue_house how long ya been working eith computers?
02:46 Geneva_Mode Young, teenage, and someone stupid sometimes.
02:46 Geneva_Mode Oh, gee, since I was 5.
02:46 Geneva_Mode It's how I learned to talk.
02:47 rue_house cool
02:47 Geneva_Mode You see, I was diagnosed with autism at age 1.
02:47 rue_house so, have any money saved up for an arduino?
02:47 Geneva_Mode Not yet.
02:47 Geneva_Mode The doctors thought I'd never talk or be trained. My mother started using the computer to teach me how to talk.
02:47 rue_house well, put aside a bit a day and before you know it you ;ll have enough
02:48 Geneva_Mode I have about £30 on my credit card, I think.
02:48 rue_house I think you can download all the arduino software and start programming for it
02:48 rue_house windows or linux?
02:49 Geneva_Mode Windows.
02:49 rue_house yup, easy for arduino then
02:49 Geneva_Mode I'll brb. I'm not feeling well.
02:49 rue_house everyones asleep now
02:49 rue_house on account of the time
02:49 rue_house !time
02:49 tobbor My watch says its 00:43 Wed Dec 28 2011
02:54 Geneva_Mode Hi, Tobbor!
02:55 rue_house I need to get to sleep, I suspect if its moring there now we will meet up before you go to bed
02:55 Geneva_Mode Me too.
02:55 Geneva_Mode Night night, everyone. :)
10:23 Geneva_Mode Hello, everyone. :)
10:23 Steffanx Hi
10:25 Geneva_Mode How are you today?
10:25 Steffanx Fine, you?
10:28 Geneva_Mode I'm alright.
10:28 Geneva_Mode Didn't get up long ago.
10:28 Steffanx uh?
10:28 Geneva_Mode I mean, I just got out of bed.
10:28 Steffanx Aah, another lazy ass :)
10:29 Geneva_Mode Not lazy. :'(
10:30 Steffanx Sick/
10:30 Steffanx ?
10:30 Geneva_Mode A bit.
10:30 Geneva_Mode I tend to be tired a lot.
10:31 Geneva_Mode Do you ever get that?
10:32 Steffanx Only when i don't sleep enough :P
10:32 Geneva_Mode I was up all night last night.
10:33 Steffanx And now you are tired.. wheird
10:33 Steffanx *wierd
10:33 Steffanx Argh, english is hard
10:36 Geneva_Mode I did get SOME sleep.
10:36 Geneva_Mode I was just wondering. When you aren't making robots, what else do you like to do?
10:38 Steffanx I don't make robots :)
10:38 Steffanx I'm just here because i find it interesting to see what others do
10:42 Geneva_Mode Oh, okay.
10:42 Geneva_Mode I've yet to make my first.
10:50 Geneva_Mode Hello, Steffann.
11:08 Geneva_Mode Is anyone here?
11:15 Steffann I am Geneva_Mode
11:22 Geneva_Mode Oh, cool! (sorry for the late reply)
11:27 Steffann :S
11:29 Geneva_Mode Im just multitasking a lot.
11:49 Geneva_Mode Hello, KongfuPanda. <3
11:50 KongfuPanda hello Geneva_Mode, :3
12:09 Geneva_Mode Sorry for the late reply.
12:09 Geneva_Mode How areyou?
12:10 Steffann How are you?
12:21 Geneva_Mode I'm fine, thanks. You?
12:21 Steffann I'm alright.
12:21 Steffann Didn't get up long ago.
12:21 Geneva_Mode That's my excuse! Get your own!
12:24 rue_house Geneva_Mode, I just woke up, you almost off to bed?
12:24 Geneva_Mode Nope!
12:25 Geneva_Mode I'll be up for quite a while yet!
12:27 Steffann just woke up rue_house ?! :S
12:40 Geneva_Mode I know what I want to do.
12:41 Geneva_Mode I want to make a robot that wheels around and using LEDs to flash the peace sign.
12:44 Geneva_Mode What do you guys think?
12:47 rue_house meh, its got a goal...
12:48 rue_house \breakfast....
12:48 rue_house hmmm
12:48 Geneva_Mode What you having for breakfast?
12:49 rue_house waffles I think
12:49 neva_Mode inches his hand closer and attempts to steal a waf
12:49 e_house sicks a robot on
12:50 Geneva_Mode Yay, hugs!
12:52 rue_house at the rate they move they cant catch you if you walk away, but your gonna have to keep walking awayf ro an hour or more before their batteries die
12:52 rue_house right breakfast, shopping, bank, and take the last of the 2011 photographs
12:53 Geneva_Mode Have you guys heard of REPRAP?
12:53 Geneva_Mode It's a 3D printer that you could use to print your own gears and stuff.
12:53 rue_house yup
12:54 rue_house have you seen the rpice on the plastic for it?
12:54 joink there are basically 10s or 100s of different variants :P
12:54 Geneva_Mode Nope.
12:54 Geneva_Mode How much does it cost?
12:54 rue_house surprisingly a lot
12:55 rue_house did you want to print a robot?
12:55 Geneva_Mode Nah, I was just wondering if you had heard of it.
12:55 rue_house ah
12:55 Geneva_Mode I was thinking of printing appendages I wouldn't have been able to get in shops.
12:56 rue_house do you want to start a flatbot of your own?
12:56 Geneva_Mode Yep.
12:56 Geneva_Mode I'd like to start with a basic two-wheel robot.
12:57 rue_house I suggest start with sheels, for the ones I made, you need an old HP inkjet printer for parts, a drill, and a 3/4" "spade" bit
12:57 Geneva_Mode One you could control with a remote connected via telephone wire or something.
12:57 rue_house yep
12:57 Geneva_Mode You mean a flat-head bit? As opposed to a Philips?
12:57 rue_house no a spade wood drill
12:58 Geneva_Mode Oh?
12:58 rue_house http://toolmonger.com/wp-content/uploads/2007/09/BoschSpade2.jpg
12:58 rue_house but one without the little teeth on the edges of the bit
12:58 rue_house a cheap one, just flat except for hte middle point
12:59 rue_house that pic is of a good one
12:59 rue_house http://image.made-in-china.com/2f0j00QvZEVjOcbtbH/Wood-Spade-Bit-F1-.jpg
12:59 rue_house top left
13:01 rue_house fron a dollar store would prolly be ok
13:01 Geneva_Mode Nice.
13:01 Geneva_Mode I wonder why they're flat.
13:02 rue_house just cheap, the good ones have the points that make it drill thru things good, but you dont want that to modify the wheels
13:02 rue_house http://www.ebay.ca/itm/DeWalt-4pc-Spade-Bit-Set-DW4SPADE-/160702253326?pt=LH_DefaultDomain_0&hash=item256a99c90e
13:02 rue_house expensive, but the right thing
13:02 Geneva_Mode I don't use Ebay.
13:02 rue_house ok
13:04 rue_house there are other ways to make wheels if you want, thats the first method I'll suggest
13:05 rue_house http://eds.dyndns.org/~ircjunk/tutorials/mech/wheel/wheel.html
13:05 rue_house thats another way that dosn't apply as much to the robot you want to make
13:09 rue_house I"ll make a howto for the wheels on that robot I showed you if you can gather the parts to do it
13:11 Geneva_Mode I'm still reading up on it first. :p
13:11 Geneva_Mode But, I am a little puzzled on this part of the book.
13:14 Steffann Nice drawing rue_house
13:22 rue_house yea, I did it with my mouse in paint!
13:23 rue_house I think with my left hand...
13:29 Steffann on the 9th of october around 3 oclock ?
13:32 rue_house na
13:32 rue_house not this oct anyhow
13:39 rue_house its really odd, I just found code that someone does a LOT like I do...
13:42 Steffann :)
14:25 saschi hi
14:44 Steffann lo
16:16 rue_house uh ho, uh ho, we gone bin ary again
17:42 zhanx_ udo gedit .bashrc &
17:42 zhanx_ opps
17:55 Steffann zhanx renamed sudo to udo? :)
17:56 zhanx nope mouse touchpad fail as i was typeing and talking
17:59 Kingsy anyone around? I am programming my robot with eclipse (will trying) and it seems to have crashed on a "make all"
17:59 Kingsy what should I do? if I disconnect the robot is it possible to do damage? or is that impossible?
18:00 Kingsy actually, I received a timeout eventually.. I wonder why that happened.
18:00 Kingsy Reading | avrdude: stk500_2_ReceiveMessage(): timeout
18:00 Kingsy avrdude: stk500v2_recv(): buffer too small, received 32 byte into 32 byte buffer
18:01 rue_house hi
18:01 tobbor rue_house! like, totally tell us about the project!
18:01 rue_house Kingsy, tell us more about the hardware you working with
18:01 rue_house (did you ask in #avr?)
18:02 Kingsy rue_house: I am working with the pololu 3pi robot.
18:03 Kingsy I got it working through the command line, but it breaks when I try to do it through eclipse.. not sure what I am doing wrong
18:03 rue_house show me the command line that works
18:04 Kingsy rue_house: http://pastie.org/3087444
18:04 rue_house no makefile eh?
18:05 Kingsy oh sorry missed that 1 sec
18:05 rue_house what command does eclipse try to use?
18:05 Kingsy umm no, no make file --> /usr/bin/avrdude -c avrispv2 -p m328p -P /dev/ttyACM0 -U flash:w:BlinkLED.hex
18:06 Kingsy is the final command I missed
18:06 rue_house do you want eclipse to do all that
18:06 rue_house what command is eclipse trying to use?
18:06 Kingsy hmm I assume it needs to?
18:07 Kingsy rue_house: I am pretty new to this see so I still trying to understand what everything is doing.. I will paste the eclipse console so you can see what its doing
18:07 Kingsy rue_house: http://pastie.org/3087458
18:08 rue_house yea quite clearly there eclipse is trying to use an stk500_v2 programmer, your programmer is a avrisp2
18:08 rue_house :)
18:08 Kingsy oh lol sorry my fault
18:08 rue_house you need to find the avrdude command line in eclipse
18:09 Kingsy got it
18:09 rue_house :)
18:09 Kingsy let me see what happens.. umm
18:09 rue_house sometimes even the beat of us miss simple things.....
18:10 rue_house tho if were reminded about simple things we miss were likley to beat the person reminding unconcious with a frozen tuna
18:11 Kingsy rue_house: its giving me this information when I select the avrisp2 --> id = "avrispv2"; desc = "Atmel AVR ISP V2"; type = stk500v2; <--- is that type correct?
18:11 rue_house your working command line is
18:11 rue_house avrdude -c avrispv2 -p m328p -P /dev/ttyACM0 -U flash:w:BlinkLED.hex
18:11 rue_house eclipse is using
18:11 rue_house avrdude -pm328p -cstk500v2 -P/dev/ttyACM0 -Uflash:w:Sample.hex:a
18:12 rue_house you need to change the command eclipse is invoking
18:12 Kingsy ok
18:14 Kingsy rue_house: out it now says --> /usr/bin/avrdude -pm328p -cavrispv2 -P/dev/ttyACM0 -Uflash:w:Sample.hex:a <-- in eclipse
18:14 Kingsy what is the :a at the end?
18:15 Kingsy rue_house: http://pastie.org/3087501 <-- that is my latest console output (from my "fixed" build)
18:16 rue_house working: avrdude -c avrispv2 -p m328p -P /dev/ttyACM0 -U flash:w:BlinkLED.hex
18:16 rue_house eclipse avrdude -pm328p -cavrispv2 -P/dev/ttyACM0 -Uflash:w:Sample.hex:a
18:17 Kingsy looks the same to me apart from order and the :a .. unless I am being blind?
18:17 Kingsy not having a space between the switch and the value doesnt matter does it?
18:17 rue_house shouldn't
18:17 rue_house I dont know what the :a is
18:17 rue_house can you get it out?
18:17 rue_house ah, try this
18:18 rue_house command line, do avrdude -cavrispv2 -pm328p -P/dev/ttyACM0 -Uflash:w:BlinkLED.hex:a
18:18 Kingsy hmm no I cant see why its appearing in the setup
18:18 rue_house see what happens
18:19 Kingsy sure 1 second..
18:22 Kingsy rue_house: wow.. wtf.. it worked?
18:22 Tom_itx why wouldn't it?
18:23 Kingsy Tom_itx: because the exact same command doesnt in eclipse
18:23 Tom_itx so why are you still using it?
18:23 Kingsy could the MCU clock frequency being wrong cause the issue perhaps?
18:23 Kingsy its still set to the default..
18:23 Tom_itx i doubt it
18:24 Tom_itx defaults are set to lowest denominator on purpose
18:24 rue_house same avrdude command
18:24 rue_house works command line, but not from elcipse
18:24 rue_house see why I dont use '
18:24 rue_house everything' IDE's?
18:24 Kingsy Tom_itx: I am using it because it would be nice to run through a IDE..
18:24 Kingsy rue_house: haha yeah
18:25 rue_house try arranging the command line exactly like they have
18:25 Tom_itx so just leave a terminal open for avrdude
18:25 rue_house maybe there is something we missed
18:26 Tom_itx keep a sharp eye on rue, he's been a bit wobbly lately
18:26 e_house readies the frozen
18:27 rue_house me and the roommate went down to the beacha nd got some firewood
18:27 Tom_itx nice
18:27 rue_house we have it dripping dry out in the rain as we type
18:28 Kingsy lol I will take a closer look, thanks guys
18:28 rue_house :/
18:28 Tom_itx driftwood?
18:28 rue_house yea
18:29 Tom_itx it'll go off quick
18:29 rue_house haha not in flame
18:29 KongfuPanda rue_house, is it for barbeque?
18:29 Tom_itx well when it's dry it will
18:29 rue_house no
18:29 Tom_itx rue has a heat plant
18:29 rue_house its for the boiler that heats the house
18:29 KongfuPanda oh, lol
18:29 rue_house oh I should make that circuit
18:29 rue_house damn
18:30 rue_house I forgot to put that on my list for today
18:30 KongfuPanda rue_house, do you live in France?
18:30 rue_house canada
18:30 KongfuPanda I see
18:30 KongfuPanda when i was in France they had a lot of houses with firewood boilers
18:30 rue_house not the stupid east end either
18:30 KongfuPanda I haven't seen any in England
18:30 rue_house my boiler is out in the yard where burning down wont be a insurance issue
18:31 Tom_itx i think i missed the cutoff for chinese newyear
18:31 Tom_itx i'll have to wait now
18:33 KongfuPanda Tom_itx, chenses new year is in FEbruary ?
18:33 Tom_itx they take like a month off
18:34 rue_house somewhere in a million sheets of paper I have a doc that tells me how the io bank on the boiler is wired
18:34 rue_house *sigh*
18:34 Tom_itx but their US office is in Canada and they're off just before the factory shuts down

18:39 Kingsy guys.. what is the deal with setting a bitclock value in avrdude?
18:39 Tom_itx spi communication
18:39 Tom_itx the -B ?
18:39 Tom_itx you can specify a value to slow it down and sometimes that helps
18:39 Kingsy see I am getting this error in eclipse --> avrdude: stk500v2_recv(): buffer too small, received 32 byte into 32 byte buffer <--- I think thats cos the program I am flashing in eclipse is avrdude: input file Sample.hex contains 3368 bytes
18:40 Kingsy and the working upload on the command line was avrdude: input file BlinkLED.hex contains 178 bytes
18:40 Tom_itx You can use the -B option to specify the ISP speed. By default the value is 10 which means 100KHz clock, this is good for target clock speeds > 500KHz. If you want the high speed clockrate (400KHz) for target frequencies > 4MHz you can use "-B 1" to speed up programming
18:40 Tom_itx To calculate the SPI frequency from the delay value, use this formula:
18:40 Tom_itx SPI clock frequency in KHz = 1000/(1.5+B) where B is the delay value
18:40 Kingsy could that matter?
18:40 Kingsy i.e could that cause a timeout?
18:40 KongfuPanda Kingsy, hello !! how is it going?
18:40 Tom_itx try the -B and see
18:41 Kingsy KongfuPanda: just messing with eclipse
18:41 Tom_itx In general, the clock frequency should be at least 4 times larger than the target clock frequency. Try "-B 32" if you're having clocking issues, that should handle even 128khz clocks
18:41 Kingsy so not very well :P
18:41 Kingsy Tom_itx: cant you set clock speeds that the avr doesnt support?
18:41 Tom_itx why would you?
18:42 Kingsy Tom_itx: because I have no idea what this avr supports and what it doesnt..
18:42 Kingsy hehe
18:43 Kingsy i.e can I be certain that -B 32 will do no harm to be avr? I am probably misunderstanding what this does.. but better to be safe than sorry
18:43 Tom_itx yep
18:45 Kingsy Tom_itx: ok, -B 32 broke it, -B 3 worked how can that be going by what you said before?
18:45 KongfuPanda Kingsy, is this for that small robot with wheels?
18:46 Tom_itx so use -B 3 then
18:46 Tom_itx b32 may be too slow
18:46 Kingsy KongfuPanda: hehe yeah, still just messing around flashing LEDS and stuff
18:46 Tom_itx it didn't break anything
18:46 Tom_itx it simply didn't work
18:47 Kingsy yeah, I mean it works now, I guess I just don't understand that switch
18:47 KongfuPanda OMG, it's so much work
18:47 Tom_itx it slows down the communication between the programmer and the chip
18:47 KongfuPanda low -level stuff is really worst part
18:47 Tom_itx some programmers need that
18:47 Kingsy Tom_itx: so, the higher the value the slower the comms are?
18:48 Tom_itx read the formula
18:48 Tom_itx use this formula:
18:48 Tom_itx <Tom_itx> SPI clock frequency in KHz = 1000/(1.5+B) where B is the delay value
18:48 Tom_itx it adds delay
18:48 Tom_itx yes
18:49 Tom_itx what programmer do you have?
18:49 Tom_itx is it bitbanged usb?
18:49 Geneva_Mode Hello, everyone!
18:49 KongfuPanda Hello Geneva_Mode, how are things ?
18:50 Geneva_Mode Goood~
18:50 Geneva_Mode I'm actually feeling a little bit snuggly today. :)
18:50 Kingsy Tom_itx: its a Atmel AVRISP v2
18:50 Geneva_Mode How are you?
18:51 KongfuPanda Geneva_Mode, I'm good thanks. going to bed now. Cya :)
18:51 KongfuPanda e)_(e
18:51 Geneva_Mode Night night. <3
18:52 Geneva_Mode Hello, Kingy. I haven't met you before.
18:53 Kingsy Geneva_Mode: alright man, hows it going?
18:53 Geneva_Mode It's going just peachy.
18:53 Kingsy I am serious newbie to this, so I am on a mish to understand the lot at the moment
18:53 Geneva_Mode How about you?
18:53 Geneva_Mode I've yet to make my first robot.
18:53 Kingsy ^^
18:53 Geneva_Mode I don't even have a workspace yet.
18:54 Kingsy wow make it? I just got my first LED flashing ! :P
18:54 Kingsy but its all good
18:54 Kingsy you'll get there I am sure
18:54 Geneva_Mode Using a microcontroller?
18:54 Kingsy yeah, its all pre built tho
18:54 Geneva_Mode Is it one of those Arduinos?
18:54 Kingsy it certainly is.. how did you know?
18:55 Geneva_Mode That's the usual choice of microcontroller.
18:55 Geneva_Mode Inexpensive, easy to use, programmed in C.
18:55 Kingsy well, atmega328p
18:55 Geneva_Mode I've yet to make a robot that uses it.
18:56 Kingsy cool, good first choice then :)
18:56 Kingsy well I gotta sleep..
18:56 Geneva_Mode I'd rather make something basic that I can use to practice basic things, like soldering.
18:56 Geneva_Mode Nini Kingsy. <3
18:56 Kingsy Geneva_Mode: good to meet ya
18:56 Kingsy Tom_itx: thanks for the help
18:56 Kingsy see you all 2morrow or something :)
18:56 Kingsy laters
18:57 Geneva_Mode And you too.
22:09 rue_house !assist circuits
22:09 tobbor Possibly http://eds.dyndns.org/~ircjunk/circuits
22:10 Tom_itx did you work out your sensor issue?
22:10 rue_house http://eds.dyndns.org/~ircjunk/circuits/rtd-amp.jpg
22:16 rue_house in the process I made a program that calculates components for hte transistor amps
22:16 Tom_itx the divider just wouldn't cut it ehh?
22:17 rue_house tooo much current
