I would like to be able to turn a flashlight on and off with a wireless remote from about 20' away (or so). I figured if I get one of those big plastic flashlights with the 6 volt battery there should be room for whatever electronics are needed, but I don't know how to do it. I realize this sounds like a bit of a strange request, but it's for a theatrical production in which we'd like to be able to turn a flashlight on and off without anyone near it. Any thoughts on either where I could find something like this, or how to make something? It has to be pretty simple for me to able to do it (limited electronics ability and knowledge).
