I built a clock using those pinball reels, but (for the reason the Mr. Smout mentioned, I didn't use the original electro-mechanical drivers (although I had them). Instead, I mounted each reel on a stepper motor, and drove each stepper with a little 8051-based controller - six of them in total. I connected them all on a primitive one-directional network (along with a couple of other devices), and ran them all from the serial port of an Arduino. This worked very well, and was virtually silent. The motors never seemed to miss a step, but in case they did I had a flag and an opto-interrupter at the zero position, so each digit would verify and if necessary re-calibrate every time it displayed a zero (also at power-up, of course). ~~ Mark Moulding
