Disco Mirror Ball

[nwaste]

Can i use dc motor from car window wiper with PWM to run slow revolution disco mirror ball. I already have schematic with 4 MosFETs. And which MosFETs its best to use (How many AMPERS).
P.S.
Can you help to make a stepp motor which respond on sound (you know i mean: Signal  comes and stepper start runnin' on one direction, signal comes again stepper direction changes on oposit direction) but not to use microcontrollelr or PC.

Hi nwaste,

You can use a wiper motor with PWM no problem, but some motors have to be modified if you like to run them in both directions. A wiper motor with a small load will draw just a few A.

All fine. But do you have some advice for the second thing (stepper reacting at sound)?
