This is an easy-to-build simple solar engine, also known as a Trimmet. We will construct a direct-drive type (as opposed to a voltage-triggered) spinner that will really go nowhere fast in direct sunlight. Perfect for windowsills and desktops that get a lot of old Sol’s rays. Many different styles are possible, but this is a straight-up basic spinner that never ceases to amuse.

Step #1: Get the Motor
- Begin by obtaining a small motor, such as the one pictured here from an old CD ROM drive. They are usually soldered in place to a small board which is easily removable. Unsolder the motor from the board and discard the board.
- Other CD ROMs may have the motor held in place with small screws at the base of the motor. Remove the screws and then the motor.
