I've not seen CNC-Paul for a few weeks and - having finally got my audio
project sorted out - I'd like to look at these crazy dc servo style motors
with rotary encoders he's been banging on about ;-)
Anyway, I'm assuming that to drive a dc motor in different directions, some
kind of h-bridge is going to be in order; does anyone have any, or know how
to use any h-bridge driver chips? I've had a couple off a few people over
the years, so I'll bring them along (if I can find them). Ideally, by the
end of the night, I'd like to get precise movement over a single dc motor
with a rotary encoder on it (over usb).
Like my audio stuff, it'll all be from first principles, so Arduino motor
shields aren't going to be much use, I'm afraid.
But if anyone could bring along some motor driver chip(s) so we can compare
ideas, that'd be really great.
Failing that, I could build a bridge from some fets/power transistors, but
a driver chip would just make things easier!
p.s. @CNC-Paul you are coming along tonight?
