01:53 rue_house so, your only losing about 4
01:54 rue_house is the 8.5 from a battery?
01:55 rue_house oops I think its a library mismatch
01:56 rue_house nope, its like fgets on the remote machine is just broken
11:33 LiohAu_ deshipu: trying to choose my servos for the robotic head, do you have an idea of the rotation speed of an human head ? :P
11:36 shipu tries a human head to get an
11:37 deshipu LiohAu_: I think it's much more than you can reasonably reproduce with servos :(
11:39 LiohAu_ deshipu: 360deg/s => roll, 430 deg/s => pitch, 467 deg/s => yaw
11:39 LiohAu_ (according to kristi stevens)
11:39 deshipu good luck with that
11:39 LiohAu_ no it's victoria quesada xD
11:39 shipu tries to roll his head 360° in a se
11:40 LiohAu_ no don't try :P
11:40 deshipu (:
11:40 LiohAu_ so I have to convert this in : time / 60°
11:40 LiohAu_ servos uses this unit right?
11:41 deshipu right, just divide both sides until you get 60°
11:41 LiohAu_ well so 0.16s / 60° for "roll"
11:41 LiohAu_ what does "roll" means? it's pan?
11:41 deshipu you know airplane evolutions?
11:42 LiohAu_ I thought the 3 moves where pan / tilt / roll
11:42 deshipu roll is the barrell roll
11:42 deshipu pitch is the loop
11:42 deshipu and yaw is turning
11:43 deshipu it's the airplane terminology
11:47 LiohAu_ well in the oculus rift sdk there's a diagram about this :)
11:50 LiohAu_ yaw = pan, roll = roll, pitch = tilt
