08:11 robopal oh good
08:12 robopal you made it
08:18 veverak yeah
18:46 rue_school you put it in a box, hows it going to breathe?
18:47 rue_school veverak, is that one of rijrafs kits!
18:47 rue_school ?
18:47 veverak nope?
18:47 veverak dunno
18:47 rue_school oh
18:47 veverak he was so willing to send me a source file for his frame
18:47 veverak :D
18:48 rue_school why do yo uhave an air line cooler?
18:50 veverak R&D
18:50 veverak just wanted to try it
18:50 veverak :)
21:47 xulf hey
21:50 ace4016 ahoy
23:08 rue_school hey
23:09 rue_school I'v expanded my 2d library, I can now calc the angle between any 2 abitrary points relative to an arbitrary point
23:12 xulf rue_school: what are you working on?
23:12 xulf in general
23:13 rue_school a 2d library
23:13 rue_school specifically,
23:14 rue_school http://ruemohr.org/~ircjunk/robots/abspos/code/problem.html
23:14 rue_school I'm writing the code to do that
23:14 rue_school now that I have all the pieces
23:16 xulf I've been meaning to bring up my interests with you
23:16 xulf I want to dig a square hole in my yard
23:16 xulf but I would like to automate it
23:17 xulf How'd you go about that?
23:17 xulf 12' x 12' x 12'
23:17 xulf and then perhaps one solution that just digs to china non stop even when I'm not home
23:18 xulf 12' x 12' x infinity
23:20 rue_school just a side, what are you going to do a) with all the dirt b) with any rocks larger than 12x12 that you hit
23:20 xulf at some point I'd have to move the dirt at least 100' or truck it away
23:21 xulf I'd like to break up a rock of it's larger then 12'
23:27 xulf I'm thinking of just using a backhoe attachment without the tractor
23:27 xulf taking the backhoe and attaching it to a steel frame that's over the hole
23:28 xulf and the backhoe slides x y z position in the hole while mounted to the frame
23:52 rue_school is the amount of energy required over time a tan() relationship?
23:52 rue_school or just exponential?
23:56 xulf I'm not smart enough to understand the question
23:58 xulf oh I get it
23:59 xulf I think I should lower the frame into the ground with the backhoe connected to it
23:59 xulf so the force has a cap
