00:41 GargantuaSauce_ sweet
00:42 MrCurious i have 250' of 16/2 CL2 wire W-5216-250-CL-CL2
00:42 MrCurious anyone knowhow toe read te numbers to see if it wil be happy with 24v 2A
00:46 GargantuaSauce_ only the current matters
00:46 GargantuaSauce_ and i think 16 gauge can do 2A just fine
00:47 GargantuaSauce_ ~16 milliohm per metre
00:48 MrCurious well, i havev it in stock, so i volunteer it for testing :D
01:00 rue_mohr2 16 mohms? damn maybe if youuse silver plated wire?
01:01 rue_mohr2 tin plated silver plated copper, what can beat that eh?
01:01 GargantuaSauce_ i was just going by wikipedia!
01:01 rue_mohr2 ah, so its YOUR fault!
01:02 GargantuaSauce_ oh and i was one gauge off in the table
01:02 GargantuaSauce_ it's actually lower!
01:02 GargantuaSauce_ and it says that's for copper
01:02 GargantuaSauce_ in any case the screw terminal connections will probably be the most significant source of resistance
01:44 rue_bed terminally screwed resistance?
01:47 GargantuaSauce_ http://satsuki.gd-kun.net/zilch/resistance.png
01:56 rue_bed resistance is futile
04:36 GuShh_Lap2 GargantuaSauce_: ah... furries!
04:50 GuShh_Lap2 Ah the smells of strong poisons in a summer morning.....
09:44 Curly-Brace hello
10:09 anonnumberanon Hi
10:13 Curly-Brace hello
10:13 Curly-Brace anyone here used Tecan/Cavro robots before?
10:13 anonnumberanon Hi
10:13 anonnumberanon negative
10:13 f00bar80 I'm again asking if anybody can point me to a very basic starting guide on how to start building a robot brained by a Raspberry PI ? as all the guides I found either using an intermediate knowledge level or expensive components. Your help is greatly appreciated.
10:22 anonnumberanon f00bar80,
10:22 anonnumberanon http://letsmakerobots.com/node/39342
10:22 anonnumberanon did you check out this one?
10:33 f00bar80 anonnumberanon, there's what's called BrickPI board don't know if you heared about it , do you think it's better than Arduino ?
10:34 anonnumberanon You havent't bought a RapI yet?
10:34 f00bar80 anonnumberanon, actually what i'm looking to get is more simple than that, just the raspi board on 2 wheels which controls them back and forth
10:35 f00bar80 anonnumberanon, i already have the raspi Model B
10:35 anonnumberanon Do you have motors and wheels?
10:36 f00bar80 anonnumberanon, i'll much appreciate your help if you can guide me where/which i can get
10:38 f00bar80 anonnumberanon, i think something like http://letsmakerobots.com/node/38857 is simple , if i'm wrong
10:40 Curly-Brace thanks anyway
10:41 Curly-Brace oooh, Pi robots?
10:41 anonnumberanon f00bar80, did you try ##electronics ? You'll get instant help there. I haven't built bots yet. If it was me I would use some lower level stuff like the arduino or msp 430
11:36 f00bar80 Anybody can point me to the actual construction guide of a very simple robot?
11:37 f00bar80 I'll much appreciate your help if you can guide me where/which motors/wheels I can get?
11:44 anonnumberanon Have you tried ##electronics?
11:48 DLC f00bar80: http://www.e-puck.org
11:49 DLC f00bar80: this is a pretty simple robot with open-source hardware/software
11:50 f00bar80 DLC which can be brained with RaspberryPI?
11:53 DLC f00bar80: maybe, but for low-level control stuff arduino might be a better choice
11:53 DLC f00bar80: in other words i have no clue
17:02 MrCurious and supported rods AND bearing have now arrived
17:04 MrCurious and the threading is compatiblle!
17:05 Tom_itx i'd hope so
17:06 MrCurious they are 1 - 2 mm difference in total height from hearing mount to rod pillow
17:06 MrCurious but nothing some washers wont solve :)
17:06 MrCurious 3 weeks off
17:07 MrCurious and enough kit here to have fun with that time
17:07 DLC robot santa?
17:07 MrCurious oh yeah
17:07 MrCurious but you heard santa resigned
17:07 MrCurious NSA gave him an offer he couldnt refuse
17:07 MrCurious apparently the ability to see people when sleeping and when awake, knowing if they are bad or good was a skillset in super high demand
17:08 MrCurious i imagine a few years of NSA pay, and santa will be buying facebook
17:09 DLC South park did an interpretation of that
17:11 MrCurious so did futurama
17:12 MrCurious 2 interviews that went well yesterday, 3 weeks of vacationn starting yesterday, new cnc parts, and other misc roboticcs bits on the way. i feel a good mood coming on
17:12 DLC sounds good
17:13 MrCurious was amazed that a programming job interview would have noticed my robot/cnc hobby and found it of value
17:14 MrCurious if i get an offer, i will be able to tell my wife it was an investment that paid off :)
17:14 DLC google likes robots so everyone likes robots
17:14 MrCurious and if not.... i can tell her oh look! it blinks!
17:15 MrCurious guess he couldnt be bothered to give a ping
17:16 MrCurious oh yeah, and i have (20) 6x6 mono crystiline grade A solar cells and tabs to experiment with too
17:17 MrCurious neighbor got profesional solar panels put up. now i need to make something to mock his....
17:17 DLC I wouldn't expect to be able to use those around where I am until at least june
17:17 DLC I thought I had gone colourblind yesterday, but it was just the weather
17:28 DLC So is this channel mostly discussing robotics from a hardware point of view or also algorithms?
17:29 Tom_itx yes
17:33 DLC Xor
18:07 GuShH_Lap MrCurious: what did they give to your cat when it was time?
18:08 GuShH_Lap I should sue these vets all they were willing to do is rip me off at the expense of the cat's and my suffering
18:18 upgrdman what did they charge?
18:22 GuShH_Lap upgrdman: that's irreelvant, they were just trying to cash off of the cat's cancer
18:23 GuShH_Lap and instead of just getting rid of his leg so he could live a few more healthy years they went with invasive medication and nonsense bullshit, now it lost too much weight and has had convulsions. I've been through this with my dog once... I don't want the cat to suffer anymore.
18:23 GuShH_Lap they were always "there's a chance we can save the leg" which was indeed bullshit to rip us off at the cat's expense
18:24 GuShH_Lap doesn't take a medic to know what's next, like I said I've dealt with it before.
18:29 Tom_itx they're not there to help you, they're there to help themselves
22:43 MrCurious quick poll: santa claws.... what color, what political affiliation?
22:45 GargantuaSauce black supremacist, obviously
22:48 MrCurious thankyouo for flashing me to the robot "percy" from ice pirates
22:50 MrCurious http://www.badmovies.org/othermovies/icepirates/icepirates2.jpg
23:16 MrCurious too cool http://digg.com/video/this-music-video-will-melt-your-brain
23:16 MrCurious i think it is activating more neurons than normal
23:20 MrCurious can anyone make out the language? hindi?
23:26 GargantuaSauce maybe
23:26 GargantuaSauce not a fan of the music but the video rules
23:27 GuShH_Lap MrCurious: he's gone...
23:28 GuShH_Lap way to end the year
23:28 MrCurious who is gone?
23:28 GuShH_Lap my cat
23:28 MrCurious i am sorry
23:28 MrCurious he had a good life?
23:28 GuShH_Lap I wanted him to go peacefuly but they didn't give me the meds to do it
23:28 MrCurious he knew how you felt about him, and you knew how he felt about you
23:29 GuShH_Lap I'll be crying somewhere around the house...
23:29 MrCurious yes
23:30 MrCurious remember, he would want you to go on, and think fondly of him
23:30 MrCurious cats are not very vindictive creatures
23:31 upgrdman wait, so you killed the cat? that's a sad and difficult way to put em down :(
23:31 GuShH_Lap no you asshole he died of cardiac arrest I didn't want it to go that way
23:32 GuShH_Lap I knew it was going to happen today
23:32 upgrdman i wasnt blaming you or anything
23:32 upgrdman im a cat person too
23:32 upgrdman im sorry for your loss
23:32 MrCurious cats tell you when its time to go
23:32 GuShH_Lap He was terminal but they didn't even care to hand me the meds to end it and they didn't even care to come over here to do it
23:33 GuShH_Lap MrCurious: he had an episode before and he recovered but not this time, it's the same thing I had to go through with my dog, exactly the same and it sucks because vets here are dipshits
23:34 upgrdman do vets ever make house calls?
23:34 GuShH_Lap they don't talk about ending it they want to squeeze every penny off your pocket instead and that's just cruel for the animals
23:34 GuShH_Lap they do
23:34 GuShH_Lap but only when there's extra money to be made
23:34 upgrdman is there only one vet near you?
23:34 MrCurious same ilness in 2 animals of diferent species
23:34 MrCurious you have something bad in teh house they are getting in to?
23:34 GuShH_Lap I moved
23:35 GuShH_Lap But they both spent most of their lives at the previous place
23:36 MrCurious this is SICK http://earth.nullschool.net/#current/wind/isobaric/1000hPa/orthographic=-94.18,10.31,285
23:36 GuShH_Lap Someone told me bad cells are bound to fire off and reproduce given the right conditions, stress, etc. Moving is very stressful for anyone... but I don't know, I've thought about it maybe the water at the old place?
23:36 upgrdman wow. it's kind of neat to watch the output of my gyro as vdd falls (battery drains) ... +15dps offsets
23:36 GuShH_Lap it was municipal mains...
23:37 ShH_Lap has been buying bottled water ever since he moved th
23:37 GuShH_Lap after visiting the water treatment plant I didn't want to drink any more of it... to think ferric chloride is part of their process!
23:42 GargantuaSauce it is not unlikely that the bottled water is treated the same way
23:42 GargantuaSauce pretty standard stuff i think
