I'm trying to make a clock which its hands move fast, as fast as around 30rpm. Preferably it will cycle like a regular clock, just sped up. Should I attach a motor to the set hand dial on the back?
The motor I have at the moment is a DC motor 12v 36rpm except it is really noisy and it needs to be powered by batteries, and I don't think it will last for the length of time I need it to, around 2-3 hours of continuous rotation.
How do I attach it so the motor controls the dial? Do I need to use gears? I'm after the simplest, most efficient solution, please help me!
