Hi, I'm building a project, the mechanics of which I've got covered. The tricky bit is the electronics side.
It's to control a small motor and gearbox to drive a cam in 180 degree steps in either direction... It's reciprocating like the old carousel slide projectors. Yes I could us stepper motors, but I want it to be simple DC operation.
I've been toying with the use of a micro switch to control its end stops, which don't have to be 100% accurate because there is some play at each 180 degree stop.
I was thinking a 12v supply could be charging a capacitor. When a pulse signal is sent, this capacitor would discharge through the motor... but then all my brains started to melt.
Any thoughts on this would be brilliant.
