00:18 rue_house and interesting thing, they are rated in mWh, instead of mAh, which is kinda cool, cause its a much more usable number
00:19 rue_house the 1.3Ah li-ion battery I tested put out 1.6Wh
02:05 Hukka rue_house: Then we can start hoping for Wh numbers for different power levels, i.e. ragone plots
02:09 rue_house ?
02:10 rue_house I think Wh make more sense than Ah
02:10 rue_house Ah seem really ambigious
02:10 Hukka Sure
02:10 Hukka But Wh can't be a single number, really
02:10 Hukka It depends on the power the battery is discharged with
02:10 rue_house but its voltage independant
02:11 rue_house your saying it has the same problem as Ah
02:11 Hukka Well, they all interdepend somewhat. I mean higher power makes the voltage dip a bit, usually
02:11 Hukka I'm saying that a single Wh is just measured with a single discharge power, usually very low
02:12 Hukka See http://www.candlepowerforums.com/vb/showthread.php?276446-Mapping-Battery-Performance-An-Intro-to-Ragone-Plots for what I mean
02:12 rue_house so is Ah, at C/20
02:12 Hukka C/20 isn't power
02:13 Hukka It's current
02:13 rue_house no, its current
02:13 rue_house the 20Ah rate
02:13 Hukka So Wh is more useful than Ah, yes
02:13 Hukka But it's not as useful as a plot of Wh/power would be
02:13 R0b0t1 http://www-fp.cs.st-andrews.ac.uk/hume/index.shtml
02:13 R0b0t1 functional automata based programming
02:13 b0t1 flips t
02:13 R0b0t1 I thought my idea was unique :(
02:14 rue_house no idea is unique
02:14 rue_house someone somewhere is comming up with the same ideas as you, and they just might what it takes to do something right NOW with them
02:15 R0b0t1 Yeah that phenomena where mathematicians will have the exact same proof formulation, even with no contact
02:15 R0b0t1 :(
02:50 rue_house http://eds.dyndns.org/~ircjunk/projects/EVtruck/batteries/main.html
02:50 rue_house anyone see things to correct?
02:53 RifRaf wow you made a webpage
02:54 RifRaf will read later on, gotta get something modded so i can print
02:54 rue_house I made a load tester and took apart a china li-ion battery
02:54 RifRaf yep i saw some of it
02:55 RifRaf this appeared on my printer this morning, is alot smoother than it looks http://imagebin.org/268371
02:56 rue_house you gonna scale it and use for foxy?
02:57 RifRaf is not that far off really, but prints so well without any support
03:04 Jak_o_Shadows acetone bath it
03:04 Jak_o_Shadows You know, later, not right now.
03:06 RifRaf yeah might, will also print in better colour, the camera is showing up the lines alot but is really rather smooth to feel
03:07 RifRaf am printing new printer parts in black as well but they are not as nice to look at
03:07 RifRaf the black seems to be alot better than the white abs for parts staying in 1 peice
03:08 Jak_o_Shadows Yeah, I can imagine that black would look worse
03:08 Jak_o_Shadows especially through a camera
03:10 RifRaf yep, if i put camera on auto looks fine, but wanted to expose the black
03:14 RifRaf man i hate editing unparametric openscad code, really need to learn this properly
03:40 GuShH rue_house: that's an unprotected cell, protected ones have the round pcb on the bottom, and you can tell by looking at them, it's spot welded, there's usually a strip of kapton tape as insulator for one of the tabs (the one that goes all the way to the positive terminal, which is switched by the circuit in the pcb)
03:40 GuShH and cardboard or similar insulator for the bottom side.
03:42 GuShH I would not choose any of these chinese cells for a vehicle
03:42 GuShH they're second hand to begin with.
03:43 GuShH and without a per-cell management system, you are looking for trouble.
03:44 GuShH it's not a matter of charging and discharging them properly, if you don't monitor and balance, you might as well dead-short them and stare at the fireworks.
03:45 GuShH don't take lightly what I said about second-hand, these are used cells.
03:47 GuShH they have sorting stations where they grade the cells they receive, from third party recycling companies...
03:49 GuShH also, why is it relevant to you the 250mA discharge rate, is this what you chose for your pack per-cell?
03:50 Tom_itx apparently so
03:50 GuShH 4.9Ah was the original spec of the cell, but it being used will never reach that capacity ever again.
03:50 Tom_itx iirc this is for an electric car
03:50 GuShH yes a truck
03:51 GuShH I would only consider these cells if I were to come up with a fully modular design where small packs made up the big pack, but only with complete per-cell monitoring, otherwise you'll be in for a lot of trouble with these used cells.
03:56 GuShH lol http://lumberjocks.com/charlton/blog/8672
03:56 RifRaf seems like a pretty crazy idea, but at least he knows about fire extingishers
03:56 GuShH hahah
03:57 GuShH it's not crazy, just time consuming and expensive if you want to do it right
03:57 GuShH I can't find the product page for stanley's racing stuff
03:57 RifRaf yep, and using $2 cells that are 1/5 there rated capacity does not seem the best starting point
03:58 GuShH was it a limited edition or what the hell, my brother bought a nice mechanics set (it feels like craftsman quality to me) for relatively cheap and I wanted to find the specs / parts list
03:58 GuShH compared to regular stanley stuff, it's miles away
03:59 RifRaf heh i really musy have a freaky cheap drill press, is currently in use on loungeroom floor
03:59 GuShH too bad it's only metric
03:59 RifRaf is quiet, accurate and drills perfect holes all the time
03:59 GuShH RifRaf: you must show us this freaky press
03:59 GuShH maybe it was one of the ones that past the full QC and was deemed to be sold for some big name company but they misplaced it with the other pile?
04:00 GuShH that's my theory, they put out stuff from the factory and sort by quality.
04:00 RifRaf will take a photo now
04:00 GuShH the chuck on mine is crap and useless
04:00 GuShH that alone has 1mm to 2mm runout
04:00 GuShH (no load, with side load)
04:01 GuShH on the spindle I got much less, but the quill just flops about when you lower it, the setcrew wasn't even machined properly it wasn't riding on the groove, fixed that, but it makes uneven contact because it probably wasn't milled properly.
04:02 GuShH one of the pulleys was a bit titled, but it was due to the setscrews, for some reason they used two on the motor and only one on the spindle, massive casting defects on that pulley by the way, but I don't mind.
04:02 SquirrelCZECH RifRaf: wow, wanna help with the openscad code?
04:02 GuShH corners were sharp as heck, pulleys too tight in the grooves as well...
04:02 GuShH at least it has double bearings
04:02 RifRaf SquirrelCZECH, i got there, but would be happy to post the code
04:03 RifRaf will just get this pic uploaded first
04:03 SquirrelCZECH RifRaf: I got used to write parametric these days... so maybe O:-)
04:03 ShH stares at the incoming s
04:05 Faek Is it staring back?
04:05 GuShH this is awesome http://www.youtube.com/watch?v=Nyjl_uWy_KQ
04:05 GuShH I think I'm looking at it's arsehole.
04:06 GuShH jump to 0:25 for the interesting bit.
04:07 RifRaf GuShH, http://imagebin.org/268375
04:07 GuShH same cast as mine but are those plastic pulleys?
04:08 GuShH I can't figure out why they all have the capacitor on the back instead of the side
04:08 RifRaf not plastic, cast i think
04:08 GuShH 8uF on mine, measures 7.9uF, it's within the 5% (at first I thought the motor wasn't running properly=
04:08 GuShH cast what? heh
04:08 RifRaf black stuff
04:08 GuShH anodised alu?
04:08 GuShH black stuff could be anything sir.
04:09 GuShH the belt seems wider though and with more clearance on the pulleys
04:09 RifRaf i know, makes a metal noise when i tap with spanner
04:09 GuShH that certainly plays a role
04:09 RifRaf is even original belt
04:09 GuShH mine already shows signs of wear.
04:09 GuShH I don't know if I should keep it or replace it
04:09 RifRaf replace, you definatly don't sound happy with it
04:10 GuShH see the nut and setscrew right where the spindle is, if I set it tight the first 1CM of travel is fairly slop free, but the remaining 4 are almost unreachable with all the force I have to apply
04:10 GuShH but my thinking is the replacement will also have problems, maybe other problems, but problems nontheless.
04:10 GuShH and I can't have them open up every box and test each one of them.
04:11 GuShH am I asking for too much? I think you just got one of the odd good units and I got one of the common bad ones.
04:11 RifRaf yeah, maybe you can make it better than stock once you fix it up
04:11 GuShH here's the other option, at three times the price (divide by 5.6 for USD) http://www.sodimac.com.ar/DetalleProducto.aspx?id=250938
04:12 GuShH claims bullshit such as laser guide (...) but I've seen it, twice as big and feels sturdy compared to this one.
04:12 GuShH still, having to spend three times as much just to drill some vertical holes is rather annoying and right now I can't afford it.
04:13 GuShH the good thing about it, 3 pulleys.
04:13 GuShH so it's actually meant for metal working
04:13 GuShH 16mm chuck, cheap chuck.
04:14 RifRaf SquirrelCZECH, my convoluted code, you will require the file reference in the first line to make it appear correctly, can paste that too if you need http://pastebin.com/32X2C36T
04:16 SquirrelCZECH wow :D
04:16 SquirrelCZECH RifRaf: did you heard about "module" ?
04:16 RifRaf roundCornersCube.scad http://pastebin.com/VCMMk1Ff
04:16 SquirrelCZECH I see a lot of repeated code
04:17 RifRaf SquirrelCZECH, yes am trying to use it with newer files
04:17 RifRaf yep :(
04:17 RifRaf it will compile but wat a pain to edit, i don't expect you to fix, just showing my lovely coding abilities :)
04:18 GuShH RifRaf: last question... does your motor overheat after just a few holes? (does it feel hot to the touch)
04:18 SquirrelCZECH RifRaf: and you have even some "tab" errors :D
04:18 GuShH because I ran about 10 holes (~3mm on 6mm mild steel) and it got to the point where I had to stop to prevent damage.
04:18 RifRaf GuShH, never, and have used for hours at a time when doing hundreds of pcb holes etc
04:19 GuShH so we're looking at aluminum windings or something is really off here.
04:19 RifRaf and nor when doing say 50 holes into 6mm plate for when i was making bigger things
04:19 GuShH it's odd that it would overheat after so little work in my case.
04:19 RifRaf like holes to do old school rivets with ball peen hammer
04:19 GuShH let's see how much time I've got to replace it, if I haven't run out of time... I'm not sure if it was 3 or 30 days (varies between stores here)
04:20 GuShH I need this for a project and as it is, I can't really use it
04:29 GuShH yup got 2 more days to replace it... will make them bring another one and I'll have it tested right there whether they like it or not, if it also sucks I'll have them test the bigger one, if it's running like it should I'll put the rest of the money and take it as a lesson. I think I can do that, otherwise it's a complete loss.
04:32 RifRaf ok printing, took an hour to change from 2 x LM10UU bearings to LM8UU bearings :/ but got there
04:32 RifRaf ran out of 10mm smoothrod
04:33 RifRaf SquirrelCZECH, in time i might try fix all this code as i do want to share the files, but they can just have stl's for now as i don't need to be told how bad my code is, the end result is pretty though'
04:34 SquirrelCZECH :D
04:34 SquirrelCZECH RifRaf: I know that
04:34 RifRaf its a big learning experience for now
04:34 SquirrelCZECH RifRaf: to be honest, but code is rarely commented O:-)
04:34 RifRaf the few comments are for my sanity
04:34 RifRaf need alot more
04:35 SquirrelCZECH yep
04:36 RifRaf ok now can get back to filing parts for next printer frame, is not much but parts are not going together straight of the router when cut in solid aluminium
04:36 SquirrelCZECH RifRaf: http://pastebin.com/PLN9UKi7
04:36 SquirrelCZECH my piece of code...
04:37 SquirrelCZECH this is one after "get it ready to past to internetz"
04:37 SquirrelCZECH http://pastebin.com/8ci2pLjw and this one is before
04:37 RifRaf yep pretty, i need to look at more examples and study others code that know what they are doing
04:38 SquirrelCZECH don't ask me
04:38 SquirrelCZECH I am not really sure what 1/2 of code in the second link does
04:38 SquirrelCZECH I always have to "figure it out"
04:38 RifRaf thanks goodness for #
04:39 SquirrelCZECH :D
04:39 RifRaf so you can at least find the part
04:39 SquirrelCZECH exxactly!
04:39 GargantuaSauce i find with openscad you have to comment pretty liberally in order to make it not illegible a day or two after it's written
04:40 SquirrelCZECH GargantuaSauce: depends on complexity?
04:40 SquirrelCZECH I would say :D
04:41 uirrelCZECH do not have problems with his part after few minits of figuring it ou
04:41 RifRaf SquirrelCZECH, were you able to view the part?
04:41 SquirrelCZECH RifRaf: I prefer the "ctrl+d" -> comment
04:41 SquirrelCZECH RifRaf: didn't tried
04:41 SquirrelCZECH I do not use the code editor of openscad
04:41 SquirrelCZECH I've got external
04:42 RifRaf will upload a pic
04:44 RifRaf http://imagebin.org/268378
04:45 SquirrelCZECH wow
04:45 SquirrelCZECH looks complicated :D
04:45 SquirrelCZECH X-carriage I suppose :D
04:45 RifRaf yep
04:46 RifRaf GuShH, we had -4C this morning, was beautiful, so nice to drive to work looking at the crispy white landscape
04:46 SquirrelCZECH RifRaf: one thing
04:46 RifRaf best frost this year
04:46 SquirrelCZECH rotate ([Angle,0,120+rotatebottom]) union () --> you know you do not have to write union() there?
04:46 SquirrelCZECH just rotate(){}....
04:47 RifRaf there may have been a reason and i made changes
04:47 SquirrelCZECH ok, just askin :D
04:47 RifRaf but yes, still learning to correctly order statements
04:47 SquirrelCZECH but I would bade this part a lot more modular
04:47 uirrelCZECH just used OOP in programming a lot so he likes ... module
04:48 RifRaf yes will do, i use that same threadless bearing assembly in 4 different parts
04:48 RifRaf and they are all different now
04:49 RifRaf should just import the code into each part and change the bearing angles
04:49 RifRaf i know sorta how to do it now, but have not the time to rewrite yet, still just experimenting
04:50 SquirrelCZECH yes
04:51 SquirrelCZECH just something like "module bearings(angle=90){}"...
04:51 RifRaf yep
04:54 RifRaf SquirrelCZECH, using an external editor would be great, need to start doing that too, hate not being able to undo
04:54 SquirrelCZECH :D
04:54 SquirrelCZECH RifRaf: to be honest
04:54 SquirrelCZECH my first reason to do so
04:54 SquirrelCZECH is dualscreen setup
04:54 SquirrelCZECH (code on left, openscad on right)
05:33 GuShH RifRaf: 3�C here
05:34 Faek Sdrew that. Too cold
05:34 GuShH it only gets colder the following days.
05:36 RifRaf had 3 morning below 0 here now, i love it
05:37 RifRaf today they even had -0.6C in town near the beach, thats pretty rare, was -10 up the mountain
05:37 GuShH heh
05:40 RifRaf GuShH, wats the time in AR now? is 8.25pm here
05:41 GuShH 7:25AM
05:41 GuShH ok 7:26...
05:44 RifRaf k
05:44 GuShH uploading vid of the drillpress showing play... darn it takes long...
05:46 GuShH and it's low res...
05:46 RifRaf good, still no bandwidth here
05:46 GuShH monthly limit?
05:46 RifRaf i must be on 64kb or so
05:46 RifRaf yep
05:46 RifRaf just a cheap wireless connection, no point having a landline
05:46 RifRaf if i need big stuff i get it at work
05:58 GuShH http://youtu.be/SM6XvUSwXbU
05:59 GuShH hard to show the vibration but as you can see, stuff falls to the ground as it dances around... and being able to wiggle the spindle by hand like that is just plain wrong. but the worst part is the overheating of the motor.
06:00 RifRaf thats play sucks, just tryed to wiggle mine like that and no play at all after 5 years
06:01 GuShH it has play in every possible direction and it's brand new heh
06:01 RifRaf you never gonna be able to dril a decent hole with that thing
06:01 GuShH see, I wasn't making it up!
06:01 RifRaf yep
06:03 RifRaf how can they even seel crap like that
06:03 RifRaf sell*
06:03 RifRaf it looks shiny and new though :)
06:03 GuShH not sure... worst part is I couldn't test it on the store because it comes all packed in a tiny box
06:04 GuShH 5 days for a replacement for electric tools, 30 days for anything else.
06:05 GuShH I just think the replacement will be as bad and I'll end up having to swap it for a more expensive one...
06:05 RifRaf its not acceptable
06:05 GuShH or get medieval on their arse to demand a refund.
06:06 RifRaf you might get a triangle hole at best with a decent bit, but will snap any small bit quick smart
06:07 GuShH that's what happened the first time I tried it, snapped a brand new 3mm
06:07 RifRaf yep i remember, and can see why now
06:07 GuShH this sucks, why do I have to waste time and money over this kind of thing always
06:08 RifRaf i looked at real drill presses in a catalogue at work today, about $500 for a small unit and $1000 for a decent size, i feel lucky now to have a $68 machine that just keep working fine
06:09 RifRaf and then they just get more costly than $1k if you want a floor standing press etc
06:10 GuShH heh yeah but I wouldn't have the space for it, assuming I could buy one
06:11 RifRaf i really have abused it as well, got some 5/8" bits with a small top to fit in chuck and even they work
06:12 GuShH this chuck slips with a 3 or 4mm bit .. I didn't show it on the video but the jaws flop about when it's open
06:12 RifRaf looks like your belt is slipping quite a bit too, takes a while to reach the correct speed
06:12 RifRaf or chuck
06:15 RifRaf and looks like you have it on lowest speed as well
06:15 GuShH near the slowest, changing speeds doesn't help with vibrations (and to drill mild steel I wanted to go slow)
06:16 RifRaf yep
06:16 GuShH it's useless anyway. waste of iron and steel.
06:16 RifRaf since i use 12 to 18k at work all the time i keep mine pretty fast usually, unless its very thick plate
06:16 RifRaf yep agreed
06:17 GuShH at high speed it actually vibrates more. the belt is not uniform either.
06:17 RifRaf total waste, please at least try swap or return it, you will never be happy with that, and nothing worse than an unhappy gus
06:31 -hobana.freenode.net:#robotics- [freenode-info] why register and identify? your IRC nick is how people know you. http://freenode.net/faq.shtml#nicksetup
06:53 theBear all jaws flop when open, that's irrelevant
06:55 RifRaf hows things theBear
06:55 theBear eh... ya know
06:55 theBear and you ?
06:56 RifRaf bloody good, 3 weeks pot free and almost enjoying it, every nights sleep is like going into another world re. dreams, but some nights is just crazy shit
06:57 theBear woohoo
06:58 RifRaf getting so much more done, am not retired, just seeing wat the other side is like
07:01 theBear heh, that's probly good... i'd like to say i'm not retired AND just seeing wot the other side is like, but i ain't so optimistic these days.. least i still smile
07:02 RifRaf excect noticing a big loss of creativity, used to be able to focus alot more on projects, now just all over the place
07:02 theBear that'll pass
07:03 theBear maybe not the creativity, but the focus
07:03 theBear at least a bit, depends how mentally disturbed you are to begin with, chemically speaking
07:04 RifRaf rather disturbed according to my dreams :)
07:05 theBear heh... tho seriously, i mean more medically/chemically, like if you 'should' be on medication to function anyway... i should be, just unfortunately everything they tried so far makes me dangerously psychotic, so ya know, i drink, i smoke, i swear, i'm a joke <grin>
07:11 SquirrelCZECH :D
07:25 RifRaf Tom_itx, why do you need zlog?
07:25 theBear ANSWER Z QUESTION !
07:25 theBear i know naaaa-ssssiiiing !
07:26 theBear hoGAAAAANNNN !
07:26 RifRaf i missed it? got disconnected
07:26 theBear you missed noaaaasssssiiiiiinig !
07:26 Faek Haha theBear , such a pity that got cancelled without a final ep
07:26 theBear breaks my heart
07:26 Faek Yup
07:27 theBear heh, it's ok, my heart been broken for years
07:28 Tom_itx why does anybody need anything?
07:28 theBear because they still got hope ?
07:28 Tom_itx i do?
07:28 theBear yeah, you got a lot to live for :)
07:28 Tom_itx hope it's over soon?
07:29 theBear doesn't matter, stupid human condition never lets you give up, you can get little breaks, but then your ass humanness sneaks up while you too miserable to pay attention
07:29 zap0 didn't one of the actors get arrested for child pr0n or something like that?
07:30 Tom_itx is that supposed to be surprising?
07:30 theBear what he said or what i said ?
07:30 Tom_itx pick one
07:31 RifRaf i choose you pikachoo
07:31 zap0 i cho-cho-choose you
07:31 theBear what i said, it surprises most people... but most people don't think and/or have never given up
07:49 fRaf walked into a shop last night to buy an icecream, they were $53 each but i considered that not too bad because the paddlepops were about 1 meter long and weighed about 20kg
07:53 RifRaf anyways, think its time to go back to the neverlands again, see you on the other side, hopefully will have the energy to goto work, thank goodness its friday, sleep is way more tiring than working these days
07:55 zoplrdb \o/
07:56 theBear you goin to norway ?
08:00 RifRaf could be interesting, but no plans yet, will let you know when i return, neverland can be nowhere and also 10 places at once, is a book i never read but always get some kind of dejavue
08:00 theBear :)
08:54 SquirrelCZECH wow
08:54 SquirrelCZECH when I started to use alphabet for parts
08:54 SquirrelCZECH (part_A, part_B...)
08:54 SquirrelCZECH I never thought that I could get to letter "O"
08:57 theBear what ? you got less than 26 different kinds of components ?
08:57 theBear i got a pretty limited supply at home, but i must have a couple hundred
08:58 SquirrelCZECH theBear: for one part of vehicle?
09:00 theBear oh, still not a lot
09:05 zoplrdb lel
09:05 zoplrdb https://en.wikipedia.org/wiki/Bradley_Manning
09:05 zoplrdb They use "she" to refer to manning.
09:05 zoplrdb lel mor pls-
09:05 joga if that's what she prefers..
09:06 theBear it's wikipedia, it's stupid !
09:06 zoplrdb he hasn't had a sex change operation. It's retarded to call him "she"
09:06 joga no it's not
09:06 zoplrdb Yes it is.
09:06 joga there's more to gender than what's in your crotch
09:07 joga fortunately in Finnish pronouns are gender neutral so no change needed for wikipedia page here heh
09:08 zoplrdb Moi.
09:08 joga moimoi
09:08 zoplrdb Miten menee?
09:08 joga hienosti
09:08 zoplrdb Hyv�

09:16 SquirrelCZECH hmm
09:17 zoplrdb mmh�
09:18 zoplrdb SquirrelCZECH, What are you up to?
09:18 SquirrelCZECH picking electronics for rc airship
09:18 SquirrelCZECH I've got motor
09:18 zoplrdb Sounds good
09:19 SquirrelCZECH need to pick appropiate electronics :D
09:19 SquirrelCZECH I've got also propeller
09:19 zoplrdb Get a miniature jet engine.
09:19 SquirrelCZECH :DD

09:21 zoplrdb What did you pick?
09:21 SquirrelCZECH
09:21 SquirrelCZECH Turnigy D2836/8
09:21 SquirrelCZECH with 10x4.5 propeller, 30A ESC and just now I search battery
09:21 zoplrdb I see
09:25 zoplrdb Have you got any designs/pictures of your project?
09:25 SquirrelCZECH zoplrdb: some of them :D
09:25 zoplrdb showwwwww
09:26 zoplrdb That thing is huge
09:27 zoplrdb I thought you were designing one ~60 - 70cm in length or something
09:27 SquirrelCZECH :D
09:33 zoplrdb What languages do you know?
09:34 rue_house GuShH, I want unprotected cells if I'm making a bank over about 40V, which I am, 90V min, I'll build a balancer into the bank, (duh)
09:35 rue_house they aren't used, the specs are just inflated for sales
09:36 rue_house tho it would make sense for them to resell cells from all the barely used EV's they have over there
09:38 SquirrelCZECH zoplrdb: who?
09:38 zoplrdb You.
09:38 SquirrelCZECH czech + english?
09:38 SquirrelCZECH ore you mean programming language? :D
09:38 zoplrdb 'puter languages.
09:39 SquirrelCZECH puter?
09:39 zoplrdb 'puter.
09:39 SquirrelCZECH oh
09:39 SquirrelCZECH PHP, Python, Arduino, Openscad's...
09:39 zoplrdb Arduino is a language? Since when?
09:40 SquirrelCZECH not language
09:40 SquirrelCZECH but not sure if there is proper name for language
09:40 SquirrelCZECH which arduino uses
09:40 SquirrelCZECH so there should be Arduino's
09:40 zoplrdb Doesn't arduino use C++=
09:40 zoplrdb s/=/?
09:40 SquirrelCZECH and of course that web things like jQuery,HTML.... :-)
09:40 zoplrdb It just wraps init and loop functions in an int main(), right+
09:40 zoplrdb s/+/?/
09:41 SquirrelCZECH hmm
09:41 SquirrelCZECH arduino.cc: "The arduino language is based on C/C++"
09:41 SquirrelCZECH C/C++ for dummies I would say :D
09:41 zoplrdb uehuehue
09:41 uirrelCZECH likes it because he only knows some basics
09:41 SquirrelCZECH more like "knew"
09:42 zoplrdb I know C quite well, been learning some Perl/Python.
09:42 zoplrdb s/./ recently/
09:42 uirrelCZECH loves Python
09:42 zoplrdb You have any books on python?
09:42 SquirrelCZECH one
09:42 zoplrdb Name?
09:43 SquirrelCZECH Python 3
09:43 uirrelCZECH have to google it because he got it in his own lang
09:43 zoplrdb https://thepiratebay.sx/torrent/8783140/Learning_Python_5th_Ed_2013
09:43 zoplrdb This is real ncie
09:44 zoplrdb But don't download it, obviously
09:44 zoplrdb Buy it
09:45 zoplrdb http://www.amazon.com/Learning-Python-Mark-Lutz/dp/1449355730/
09:45 zoplrdb There
09:45 SquirrelCZECH http://www.amazon.com/Programming-Python-Complete-Introduction-Language/dp/0321680561/ref=sr_1_1?s=books&ie=UTF8&qid=1377181810&sr=1-1&keywords=Python+3 this one
09:45 SquirrelCZECH but
09:46 SquirrelCZECH zoplrdb: I do not want to buy another book yet
09:46 SquirrelCZECH I've got one to rea
09:46 SquirrelCZECH d
09:46 zoplrdb I see
09:46 SquirrelCZECH "Code Complete" :-)
09:52 zoplrdb How did you get interested in robotics?
09:55 SquirrelCZECH curiosity
13:33 rue_house I saw world domination machines and thought, "thats what I need, right there"
13:33 rue_house buy the prices were too high, so I went all DIY on it
15:12 GuShH http://gizmodo.com/this-3d-printer-could-also-be-the-worlds-first-3d-fax-1182862613
15:14 GuShH rue_house: they are used cells from laptop packs, drills, etc. most of them come from the US in shipping containers, as does the aluminum and steel they use to make all the shit they sell back to them.
15:14 GuShH it is what it is.
15:15 ShH idly faxes a 3d d
15:37 eBear idly faxes a 2d di
15:37 theBear haha !
15:38 theBear what can i say, but err, go f$*( yourself :)
15:53 GuShH lol
15:54 GuShH theBear: you could fax each 2d layer and have them assemble the dildo
15:54 theBear ahh, THEN i say go f(*$ yourself ?
15:54 GuShH I dunno.
15:54 theBear cos tbh, that's the only reason i'm in this game anymore
15:55 theBear that, and the sweet ass ho-mas
15:55 theBear i always call MY bitches ho-mas :)
15:56 GuShH you're in the game? managed to fit inside the super nintendo finally?
15:56 theBear why you think i been watching my weight ?
15:56 GuShH maybe you were planning a bank robbery
15:57 theBear err, you gotta be super skinny for that ?
15:57 GuShH "must fit inside this tunnel by the end of the week"
15:57 GuShH you won't see a fat dude doing it.
15:57 GuShH I don't think they can rob it the old fashioned way either
15:57 theBear yeah, but i couldn't be a fat dude if i tried, i know 'cos i tried !
15:57 GuShH assuming they would fit through the doors
15:57 GuShH I don't know if I could, probably
15:58 GuShH why would anyone want to be overweight though?
15:58 ace4016 to be a sumo wrestler
15:58 GuShH it's not fat it's muscle!
15:58 theBear recently i been wondering if i gotta put a ' in front of 'cos, 'cause it's not like i'm abbreviating the real word, i'm completely butchering the last half AND cutting off the first.... opinions ?
15:58 ShH snic
15:58 GuShH fuck English.
15:59 GuShH Help me retake the folklands nao.
15:59 theBear falkands ?
15:59 GuShH fartlands
15:59 theBear fawkands
15:59 theBear is that like mr spock ?
15:59 GuShH this will soon degenerate
16:00 GuShH spock on cocaine
16:00 theBear whaddy amean soon ?
16:00 ShH takes off the p
16:00 theBear heh, mine been off for 4+ HOURS
16:00 GuShH GOOD TO KNOW.
16:01 GuShH Now we can picture an accurate bear
16:01 theBear yeah that's right, HOURS... seriously tho, i accidentally hit that button next to a and shift
16:01 GuShH http://www.roddingroundtable.com/tech/articles/crush.html I don't get that second picture...
16:01 theBear everyone knows cartoon bears never wear pants !
16:01 GuShH at least one of them did
16:02 theBear err, it's obviously the radius rod bushing
16:02 theBear wtf is a crush tube ?
16:03 GuShH that's what I mean, he shows that and speaks about crush tubes
16:03 GuShH I thought crush tubes went in between screws
16:03 GuShH http://image.dhgate.com/albu_259277827_00-1.0x0/blue-bear-bib-pants-plush-cartoon-character.jpg
16:03 theBear sideways leaf springs ? wtf ?
16:03 GuShH that's how MrCurious pictures you after his second hit.
16:03 theBear that's not a cartoon, that's a giant teddy
16:03 GuShH http://image.dhgate.com/albu_335115224_00-1.0x0/children-outfits-baby-pp-pants-lovely-cartoon.jpg haha
16:03 GuShH I know, I couldn't find one
16:04 theBear actually that's why humphrey b. bear got banned here, cos he didn't have pants
16:04 GuShH wtf is that sideways leaf spring
16:04 theBear hehe, my buddies new baby has some bear-bum jamies like that
16:04 GuShH I've never seen that
16:04 theBear thus my wtf
16:04 theBear !
16:04 theBear or do i have to say WTF to get your attention ?
16:04 ShH fr
16:04 GuShH what's the point
16:05 theBear seriously, WTF MAN !
16:05 GuShH he's just welding those tubes to stuff
16:05 GuShH that's not really what I had in mind when I read crush tube
16:06 GuShH it's "crush" because it goes in between two things....
16:06 GuShH but if it's a lazy mechanic's way of saying "metal tube" then whatever.
16:07 theBear oh, like err, a spacer ?
16:07 GuShH http://www.choppersaustralia.com/forum/viewtopic.php?t=2735
16:07 GuShH WHY DOES EVERYONE HAVE A WORKING DRILL PRESS BUT ME
16:08 GuShH no shit they're choppers, they literally chop the bikes down.
16:08 GuShH (I know that's where the term came from... but still, butchers is a bit more accurate)
16:10 GuShH lol http://www.choppersaustralia.com/forum/viewtopic.php?f=59&t=2744
16:10 theBear hehehe
16:11 GuShH http://www.choppersaustralia.com/forum/viewtopic.php?f=59&t=2741
16:12 GuShH can't say I'm a fan of his work
16:12 theBear holy crap ! chair parts ! first time he hits a bump this thing is gonna turn into a taco shaped mess
16:13 GuShH and fireplace parts too!
16:13 theBear at least fireplace parts are heavy steel, not frickin thin wall crap that bends when you kick it
16:13 GuShH why do they worry so much about silly fabrication when the rest of the bike is falling apart with rust?
16:14 theBear i wouldn't exactly say they are worrying much about it, just wasting a lot of time on it
16:15 GuShH http://www.choppersaustralia.com/picture_library/CAFRearendfinished.JPG
16:15 theBear damn ! it doesn't even LOOK good, measured on any scale
16:15 GuShH I'd turn that into a cafe racer instead
16:16 theBear and sissy bar should kinda be at your back, not the back of the bike
16:16 GuShH there's no way you can turn it into a chopper without major rework
16:16 theBear maybe he got someone with REAL tight pants that wants to ride on that questionable guard ?
16:16 GuShH unless you want someone else to ride hmm
16:16 GuShH or you could have two?
16:16 GuShH heh
16:16 theBear nice how he made the guard follow the wheel
16:17 theBear oh yeah, he put pegs back there, damn !
16:17 GuShH lol
16:17 GuShH AND YOU MY DEAR WILL SIT ON THE FENDER
16:17 theBear i spose he's just sitting on a sheepskin
16:17 theBear nice helmet too
16:17 GuShH he probably is
16:17 GuShH sheepskin is awesome for long trips on ANY bike
16:18 GuShH be it an old chunk of rust or a brand new top of the line bmw!
16:18 theBear that bike actually looks 'ok' unmod'd, his one looks like a piece of shit
16:18 GuShH plus you don't have to bring a sharpie with you to draw back your arse crack every 100KM
16:18 theBear sheepskin on a seat maybe, not on the frame
16:19 GuShH yeah ok we agree he's butchering it.
16:20 theBear stock it's got that nice flat look like the old wartime bikes
16:20 GuShH http://moto.mercadolibre.com.ar/MLA-471356754-suzuki-gsx250-solo-por-hoy-3500-_JM
16:20 GuShH lol
16:20 GuShH I like how they're all missing parts and have exposed wires dangling around
16:21 GuShH that's an illegal bike right there, no paperwork.
16:21 GuShH got a netgear router here... its supplying 12V to every part of the board
16:21 GuShH safe to imagine every single IC has been fried surely
16:22 theBear i estimate one has miraculously survived
16:22 GuShH the 3.3v reg failed somehow, there must be a 5v in there too
16:22 GuShH everywhere I probe it's 12v
16:22 GuShH they should have some protection against this...
16:22 theBear you'd think so, but it's also unheard of for a reg to fail short
16:23 GuShH it was free, so whatever.
16:23 GuShH got a linksys too, but it's old crap.
16:23 theBear had a warranty once a bit like that, reg installed backwards... they actually bothered to ship it halfway around the world without ever turning it on !
16:23 GuShH those blue ones
16:23 GuShH o.o
16:23 GuShH no spec on voltage or polarity
16:24 GuShH yes polarity, no voltage
16:24 GuShH 5 or 9v?
16:24 GuShH or these older ones were all 12v
16:24 GuShH it could be they are both fried due to a bad psu
16:25 GuShH who knows how they had them connected
16:25 GuShH would be nice if I could use the linksys as an accesspoint
16:27 GuShH bad dc connector so far
16:27 GuShH but it's broadcasting and all..
16:30 theBear my wrt54g shitty version works good as a ap/bridge
16:30 theBear tho experience says that amount of ram and vxworks won't work good for nat
16:30 GuShH it's a BEFW11S4 V4
16:31 theBear i wouldn't know what that means
16:31 GuShH heh
16:31 theBear i only really know original wrt series numbers/versions
16:31 GuShH I'm in the admin panel, everything seems to work
16:31 GuShH hrm.
16:32 GuShH I don't see many options
16:33 theBear if it's broadcom based most of the options will only be available via telnet
16:33 GuShH ok what I want to do is a wifi-wifi AP (whatever it's called) which I think isn't possible with this thing
16:33 GuShH I'll need a lan link at least
16:35 theBear oh, umm, relay mode or something
16:38 theBear there are very few that do do it... worth checking the openwrt and other project compat lists, they do it good
16:39 GuShH upgrading firmware to begin with
16:39 GuShH lol "upgrade failed"
16:40 GuShH yeah not even their own firmware works.
16:40 theBear those are touchy, they like a very very stock flash from a very very stock os
16:40 GuShH bet you must jump a couple pins here and there
16:40 theBear timing is critical
16:40 theBear switches are out
16:41 theBear and now i try to sleep again before the sun comes up
16:41 GuShH what happens when the sun comes up?
16:41 theBear i feel like coffee
16:41 theBear and it gets light
16:41 theBear and i feel defeated :(
16:42 GuShH :(
16:42 GuShH added wpa password, now it won't authenticate
17:53 MrCurious GuShH: i have 2 drill presses and a mill. get with the program
18:14 RifRaf but you don't have a lathe :P
18:20 MrCurious i dont need one yet
18:20 MrCurious do i?
18:20 MrCurious i have a jointer and planer
18:21 MrCurious i am not guushh, its not like i make lathe porn
18:37 AndreeeCZ Hi. Im trying to find a simple tut on how to send an integer from raspberry (debian) to arduino via virtual com port. Do you know of any?
18:47 MrCurious Serial.print("int is about to come");
18:48 MrCurious Serial.println(i_am_an_int_variable, DEC);
18:48 MrCurious well, thats how to do it from arduino to debian
18:48 MrCurious i would google sending data to raspberry pi linux example
21:43 MrCurious i HAVE to get this hackintosh working soon so i can get back to fun robotic stuff
21:43 MrCurious why couldnt i have been born with a bigger freakishly large brain!
23:39 GargantuaSauce i am driving around my simulated hexapod with a pair of joysticks and it is way too fun
23:39 GargantuaSauce need to hurry the hell up and build a frame so it can be a real one i'm controlling >:|
23:52 R0b0t1 lol
23:53 R0b0t1 Hexapod looked like a fun thing to build with more runtime and less danger to itself than a quad
