16:41 deshipu what do you think?
16:46 veverak looks interesting
16:47 verak just finished the pain of udev and serial dev
16:50 deshipu I miss the simple days of real /dev
16:54 deshipu veverak: by the way, got Tote to do force-sensing
16:54 deshipu veverak: https://www.youtube.com/watch?v=Q08YaEeYNSg
16:54 wolfmanjm I'd prefer "Learning robotics using Ruby" ;) I hate Python
16:55 veverak awesome
16:55 deshipu wolfmanjm: ugh, how about "learning robotics with BASIC?"
16:55 wolfmanjm hehe
16:55 veverak deshipu: still using just arduino?
16:55 wolfmanjm deshipu: how did you do the force sensing? that is cool
16:55 veverak yeah
16:56 veverak how exactly? :D
16:56 deshipu veverak: yeah, I had 4 spare analog pins :)
16:56 wolfmanjm I'm getting my edison to run my quadruped, just got the 16 channel servo controller working with it
16:56 deshipu veverak: I added a wire to the one of the motor pins inside
16:56 veverak deshipu: voltage reading ?
16:56 deshipu veverak: and added a voltage regulator to power the servo with constant voltage
16:57 deshipu veverak: the bigger the force, the harder the PID inside the servo tries to compensate, and the larger the voltage on the motor
16:57 veverak :)
17:00 deshipu one problem though, I can only sense the force properly when the servo is still
17:01 deshipu not when it's moving to a new position
17:01 deshipu that's why it stops for a moment after each step
17:24 veverak nah
17:24 veverak fuck udev
17:29 veverak well
17:29 veverak it seems like handling the gamepad will be funny
17:37 deshipu veverak: the playstation one?
17:38 veverak not
17:38 veverak standart USB
17:38 veverak it's just that I want to be able to reconnect it freely
17:38 veverak but have to access it via pygame
19:58 _moon hey rue
21:12 rue_shop3 hey
21:13 Casper rue!
21:14 Casper have you ever dissassembled a compressor pressure switch?
