09:26 PM rue_mohr: its not tested to be able to stand yet
09:26 PM rue_mohr: my next step is to sit down and work out zero and scale for each axis
09:26 PM zhanx: heck i did that aleast
09:26 PM rue_mohr: yea yea
09:26 PM rue_mohr: an art gallery went and borrowed it right as I was working on it
09:26 PM zhanx: and i am SLOW at doing stuff
09:27 PM zhanx: ok good excuse
09:27 PM rue_mohr: I meant to design that all around different parts of thingiverse projects, but after the first leg segment, nothing turned out to be any good, so I had to design the rest
09:28 PM rue_mohr: it looks good, there are no assurances past that
09:28 PM rue_mohr: the stm32 can operate the 24 motors ok
09:28 PM rue_mohr: have 3 buck supplies running them
09:29 PM zhanx: you can just multiplex as 328p and run them
09:29 PM rue_mohr: stm32 -> 4017 -> 8 servos
09:29 PM rue_mohr: 3x 4017
09:29 PM rue_mohr: the stm32 could do up to 77 servos, or was it 88
09:29 PM rue_mohr: anyhow, it was a nice stm32 excersize
09:30 PM rue_mohr: its pretty borderline for weight
09:31 PM rue_mohr: kinda fun tho, designed all the pieces and threw them into a box
09:31 PM rue_mohr: sat down when I had them all and assembeld
