03:47 deshipu veverak: and they cut off the power when you activate the servos
03:47 veverak hmm
04:14 anonnumberanon GG
04:26 anonnumberanon Okay I'll have the robot kneel tomorrow morning.
04:26 anonnumberanon :)
04:31 deshipu veverak: so I rely on the voltage monitoring in software instead
04:33 veverak deshipu: that sounds more like "but lipo charger"
04:33 veverak *bad
04:33 veverak nah, will test, will see
04:38 deshipu they assume 1C 250mA lipo :P
04:42 veverak who?
05:08 deshipu the designers of the lipo charger
05:10 verak thinks that here is gl
05:10 verak assumes "make/pick proper char
05:10 veverak and it looks like deshipu is talking about one specfici charger
05:20 deshipu yeah, all the cheap chinese modules
05:25 anonnumberanon https://www.sparkfun.com/products/10217
05:31 veverak so it needs designing one
05:31 veverak nah
05:31 anonnumberanon wat
05:34 veverak deshipu: as far as I remember, cutoff circuit was not complicated much ( basically stable voltage element, voltage comparator, voltage divider and mosfet)
05:35 veverak but proper charger? daaaaamn
05:35 veverak anonnumberanon: that one is bad one :)
05:49 anonnumberanon cheap and USB, that's great for small robots and on the move ;)
06:41 veverak wat?
06:42 veverak anonnumberanon: you understand that when someone tells you it's bad, it propably is for him?
06:42 veverak like for example the fact that I want 2s battery..
06:46 anonnumberanon for what robot? im not familiar with your project
06:46 anonnumberanon I'm using 2s as well.
06:51 veverak yeah
06:51 veverak you are not familiar and you asert exactly what kind of thing I need :)
06:51 veverak sorry for being rude, but I get this behavior too much lately from people
06:52 veverak asserting things they didn't asked ...
07:09 anonnumberanon veverak, You intend on using an 8.4V battery with 5V servos?
07:10 veverak 7.4V :D
07:10 veverak anonnumberanon: not exactly
07:10 veverak thinking about 3A ubec :)
07:10 anonnumberanon 4.2 * 2 cells = 8.4 V
07:11 veverak yeah, but average voltage is 7.4 V
07:11 veverak 4.2/cell is top?
07:11 anonnumberanon yes
07:12 veverak anyway, still thinking about 5V/3A UBEC
07:12 veverak (li-po stop included)
07:12 anonnumberanon Yeah that'll work.
07:12 veverak http://www.pelikandaniel.com/products/1RC21505/d_0.jpg
07:12 veverak sweet little thingie
07:13 anonnumberanon Are you using the infrared TV remote to control it?
07:14 veverak nope
07:14 veverak nothing to control it so far
07:14 veverak I suppose I will use esp8266 til I have prepared ARM pc to control it
07:15 anonnumberanon Lots of fun choosing the right controller...
07:16 veverak rasp pi zero looks cool
07:16 veverak but I want wifi+camera on that ARM pc
07:17 anonnumberanon an arm laptop or small board?
07:17 veverak http://tote.readthedocs.org/en/latest/
07:17 veverak it's deshipus robot
07:17 veverak so it have to be light/small
07:21 anonnumberanon Yeah the Pi zero is small enough.
07:25 maiden <3 http://tote.readthedocs.org/en/latest/ik.html
07:40 rue_bed anonnumberanon, try the serial library?
07:40 rue_bed happy to help use it
07:42 rue_bed I really need to write a page for ik
08:00 maiden ^_^
08:02 maiden ah, fuck IK use q-learning: https://www.youtube.com/watch?v=-LE3BaOtXeU
10:57 akem hey
10:59 akem deshipu how do you do?
11:06 theBear i can rhyme in casual greetings too.. err, domo oregato, mr roboto :-)
11:55 rue_mohr the path q-learning came up with was horrible!
11:57 rue_mohr it obviously couldn't comprenend the complexity of a circle
13:22 rue_shop3 I had a dream last night
13:23 rue_shop3 got a lesson out of it
13:23 rue_shop3 dont go shopping without your pants on,
13:23 akem about killing all humans?
13:23 rue_shop3 wallet is in the pants pocket...
13:23 rue_shop3 tho, even if I'd had my wallet, I wouldn't have paid $57 for 2L of milk and a chocolate bar
13:25 akem rue_ss
13:25 akem e
13:25 akem ooops
13:25 rue_shop3 I think she just jacked up the price cause I came in right as they were trying to close for the day
13:26 rue_shop3 it wouldn't have taken me so long to find the stuff if they hadn't been doing a reno on the store
13:29 robopal 2l of milk and a chocolate is 57$?
13:55 maiden ^_^
17:34 maiden grr
17:34 maiden getTotalForce returns 0,0,0
21:09 anonnumberanon The robot is being really wild.
21:35 jhylands anonnumberanon, I'm working on a new body for Roz
21:39 jhylands http://puu.sh/lKWWJ/8e036e30ad.png
21:45 rue_shop3 cats do not want to be *in* or *out* they want to be going thru a doorway
21:45 rue_shop3 and not just once
21:45 rue_shop3 they want a half hour or more of going thru a doorway
22:08 Loshki rue_shop3: they're usually listening, and processing real hard. Sucks to not be at the top of the food chain. Ouch, damn mosquitoes.
22:15 anonnumberanon getting worn out with this project
