Simple DC motor controller needed?

I need as simple (read low cost) way to control motor speed for a small DC motor. The motor draws at most 0.1amp at 5 volts. I would like to use a simple potentiometer.

I am trying to develop a low cost product for crafters and they are very money conscience.

I was thinking something using a 555 timer and a few caps?

Thanks for any help.

    Well, use a pot, that's all you really need if it only runs in one direction.

    Depends on motor to some extent, but yes. To start, you need schematic/spec sheet on motor to see how it is wound and is to be controlled, including feedback if any.

    Then, just google. Try something like "pic microcontroller brushless dc motor"
