How to use a stepper-motor from old disk drives
Why and how to use components from old disk drives?
You might ask why use components from old disk drives. The answer is that disk-drives have many expensive components and you can get old bad disk-drives freely or very cheaply. They are good sources for following components with not much effort:
1. Small stepper motors and controllers
2. Optical sensors or microswitches
3. Accurately speed-regulated DC-motor
4. Useful accurate mechanic parts for small projects
