A simple "O" ring for the drive belt & a small, 2 x AA powered, Up/Centre off/Down switch & a pot for speed control through a simple voltage/current regulator.
I also included an on/off switch to conserve the batteries.
All up cost of about $10.00.

I have made one of these before also. Was after something a little different, like the 10:1 reduction knobs on the newer focusers... I have plenty of servo's laying around, being an aeromodeller you collect stuff like that
