When I originally published this instructable I used a standard RC servo and a simple control circuit using a 555 timer in the photo above.

Compukidmike was quick to point out that by modifying a continuous rotation servo (basically just using the the servo as a geared motor) and using the same switches it wouldn’t require ANY control circuitry.

Much simpler and just about any geared motor or a modified standard servo can be used. Start looking through your junk pile because Useless Machines have even been made from CD/DVD drives.

So you have a choice. Step 5 is the easy method.

If you prefer to use a standard unmodified servo then follow steps 6-9
