01:01 AM rue_: hey rue, talk to me
01:01 AM rue_: why?
01:01 AM rue_: cause, I'm the last one that exists, and if your going to live 8000 years, you gonna need to get used to it
01:01 AM rue_: I was hoping you wouldn't asnwer
01:01 AM rue_: so, whats the lead project then
01:01 AM rue_: i suppose its haptic feedback, specificially, force feedback
01:01 AM rue_: k, what do charge pumps have to do with it
01:01 AM rue_: well, D to A, via pwm or staircase conversion
01:02 AM rue_: so, need a current source
01:03 AM rue_: and swtich the source between the output of a buffer amp and an accumulator cap on its input
01:03 AM rue_: buffer amp yea, fet one
01:03 AM rue_: rail to rail fet one
01:04 AM rue_: can that be wrapped into one op-amp?
01:05 AM rue_: hmm, op-amp current soruce
01:13 AM rue_: or an integrator I can turn off/freeze
01:20 AM rue_: ok, switching the input of an integrator is done
01:20 AM rue_: but
01:21 AM rue_: you want to run the integrator for a set period of time for each clock transition
01:21 AM rue_: edge triggered monostable
01:21 AM rue_: d flipflop
01:39 AM rue_: https://i.stack.imgur.com/PEr4u.gif
01:39 AM rue_: ok, so, digital edge detector and a swtiched integrator
01:39 AM rue_: and if you want something smaller lm2907
01:40 AM rue_: gnight
01:40 AM rue_: gnight
02:11 AM mrdata: wth
02:11 AM mrdata: is that
08:10 AM tmqq is now known as dongge
11:01 AM Elleo: 7
11:01 AM Elleo: oops
03:41 PM mumptai: whats a good way to describe/programm robot behavior?
05:29 PM ace4016: probably decision flow charts and such for description
05:29 PM ace4016: at a very high level
06:00 PM SpeedEvil: Asimovs lawas.
06:00 PM SpeedEvil: (not really)
