I always thought that a neat way to turn a turntable was to use a stepper motor, but I didn't have a clue on how to control such a motor. I was surfing the other night for optical detectors and stumbled upon Hobbytron.com. (optical detector pairs were $10.00, I think they can used to run a relay which would in turn . ... .oops - off topic). Hobbytron has some stepper motor controls available. I've never played with the motors myself, but it is my understanding that a stepper motor moves in steps, each step being a set amount of degrees. It seems that by using a stepper motor you get turning plus indexing.
