Hi Lee
Two thoughts
Re stepper motors. You can often find them in old junked scanners. A
nice cheap source. If you are feeling really cheap the interface can
intially be a simple TTL counter cct and some pass transistors. I once
used one off my PC parallel port for an EzAl antenna system.
Also look at the possibility of using a piston capacitor and driving
that with a threaded bar connected to your motor. This may still be a
little fast though. You might also get away with a long lever and
threaded bar arrangement if turning a standard rotary capacitor. Kind of
limits you to something less than 180 degrees tho.
A car windscreen wiper motor is another possibility also through a
threaded bar. (Overkill on the torque tho)
