The simplist version can be made with just a DC motor (preferably a small low rpm geared motor), an SPST switch, and the visible toggle switch which is a DPDT. Oh yeah - and the battery.
tnx nice to hear good compliment
i used a:
servo (turn off the switch)
switch dpdt and spst (visible switch and not visible switch)
step motor (flag control)
simple motor (spin the box)
and micro controller
