[00:46:48] * Hyratel shares robots falling over http://hyratel.tumblr.com/post/137931619732/wilwheaton-gifsboom-video-robots-falling
[00:49:31] <Casper> some of them look like a power failure
[01:52:57] <rue_shop3> 19V across a 4mH inductor for 25us, whats the finish current, from 0
[01:57:50] <Casper> hmmm good question! I forgot the math :(
[01:58:01] <rue_shop3> yea
[01:58:16] <rue_shop3> I = (V*t)/L
[01:59:56] <rue_shop3> 118mA
[04:10:13] <hypodyne> howdy
[05:23:25] <veverak> nah
[05:23:27] <veverak> mine bash fu sucks
[05:26:50] <deshipu> Casper: it's not power failure, it's just that as soon as the robot loses balance, it stops doing anything, as to avoid damage
[05:27:15] <deshipu> Casper: those are all from last year's darpa challenge, btw
[05:27:23] <deshipu> and only from the first day of it
[06:21:06] <akem> hey
[06:21:48] <akem> was looking at a robot arm 3D printer and its just fine
[06:34:24] <SpeedEvil> What?
[06:34:53] <veverak> hmm
[06:35:01] <veverak> when I use screen /dev/ttyUSB0 115200
[06:35:05] <veverak> to connect to raspberry serial
[06:35:09] <veverak> and there I launch tmux
[06:35:18] <veverak> is there some way to tell the tmux the terminal size?
[06:38:06] <maiden> i started a new robotics course on MIT today:
https://www.edx.org/course/underactuated-robotics-mitx-6-832x-0
[06:38:21] <maiden> i think it will help a lot with my biped designs.
[06:38:36] <maiden> now, back to the 3d printer assembly..
[07:40:40] <deshipu> veverak: TERMCAP
[07:41:35] <deshipu> maiden: that's the best course I've seen in a long time, I wholeheartedly recommend it
[07:41:38] <veverak> i see
[08:27:43] <jhylands> deshipu, any idea what language they use for coding in that course?
[09:11:34] <veverak> lol
[09:11:38] <veverak> there is app for andoird
[09:11:49] <veverak> that shows ROS video stream and publishes touches back
[09:12:09] <veverak> deshipu: ^^ seems like the urge for making controller is lovered :)
[10:15:36] <deshipu> jhylands: mathematica
[10:15:44] <deshipu> jhylands: or matlab, can't remember
[10:15:55] <deshipu> jhylands: but they give you a free copy to install
[11:55:47] <rue_bed> veverak, there are things you can do with ansi terminals that will tell you
[13:26:59] <robotustra> blue smoke test passed
[13:53:29] <mrdata-> robotustra, what sort of test is that?
[13:53:36] <mrdata-> initial power up?
[13:53:50] <robotustra> yes :)
[13:53:53] <mrdata-> cool
[13:54:01] <robotustra> http://i.imgur.com/Ns04f03.jpg
[13:54:32] <mrdata-> nice
[13:54:41] <mrdata-> did you make these with a cnc engraver?
[13:54:58] <robotustra> yes
[13:55:13] <mrdata-> i like the resulting look
[13:55:46] <robotustra> after soldering it's not so nice :)
[13:56:03] <mrdata-> sure ;)
[13:56:27] <mrdata-> one thing though, should those floating copper pools be tied down?
[13:58:08] <robotustra> they are not interfering
[13:58:53] <mrdata-> good; i suppose whether would depend on subtle factors
[13:59:31] <mrdata-> to do with signalling speed, sharpness of corners, etc
[14:00:01] <robotustra> I can remove it, but it's just waste of time
[14:00:54] <mrdata-> i'm just saying, if bit rates were much higher, then you'd probably want to ground all of them
[14:01:12] <mrdata-> what speeds does this run at?
[14:02:03] <robotustra> this one are drivers for motors 0-10 kHz
[14:02:18] <mrdata-> no problems then :)
[14:05:37] <robotustra> no MHz there
[15:09:50] <robotustra> http://click.intel.com/intel-realsense-developer-kit-r200.html

[15:37:53] <robotustra> http://i.imgur.com/6KELyUf.jpg
[15:40:11] <jhylands> robotustra, that r200 camera is pretty cool
[15:40:39] <robotustra> yeah, but I don't think I'll use it
[15:40:59] <jhylands> I wonder if you could interface it to a Raspberry pi
[15:44:28] <jhylands> maybe =
http://solsticlipse.com/2015/01/09/intel-real-sense-camera-on-linux.html
[15:45:16] <robotustra> not bad
[15:45:47] <jhylands> heh
[15:45:47] <jhylands> http://wiki.ros.org/RealSense_R200
[15:46:53] <robotustra> so, it means will be supported soon
[15:47:11] <jhylands> hm, the pi doesn't have usb 3.0 support
[15:47:14] <jhylands> so it might not work
[20:25:42] <mrdata> http://www.gizmag.com/underwater-exploration-soft-robotic-hands/41433/
[20:35:35] <psYbR> i like the boa constrictor style gripper
[20:36:47] <SpeedEvil> If it was from japan, you know it's a tentacle monster not a boa constrctor.
[22:27:38] <psYbR> lol SpeedEvil i'm betting there's porn of that - "robotic tentacle attacks!"
[22:28:48] <ace4016> yes...yes there is
[22:31:50] <Casper> what is a good 3d program for linux that is the easiest to use for someone that never did 3d?
[22:33:32] <psYbR> Casper - minecraft is 3D
[22:33:58] <doomlord> 3d, cad or art
[22:34:02] <ace4016> artsy stuff or cad?
[22:34:50] <doomlord> art: blender. but Cad - ? there might be some overlap.
[22:38:26] <Casper> basically I want to do some cabinet stuff... so pretty basic...
[22:38:46] <Casper> one thing I want to do is a cart for my welder
[22:39:07] <Casper> there will be some bars at angle...
[22:48:12] <doomlord> i've no idea, i've only looked into blender, if anyone has an answer i'd be curious to know what
[23:47:54] <hypodyne> howdy
[23:48:51] <akem> hello
[23:51:30] <akem> http://m.youtube.com/watch?v=XGL35u-xssw
[23:51:49] <akem> with steppers is just fine
[23:52:45] <akem> there are cheap robot arm kits online
[23:52:57] <akem> based on servos
