Smallest RC remote possible
I haven't a clue where to begin. I'm trying to find or make the smallest RC thingie as possible with a single button remote. Can anyone please help. It would need to fit into a tube slightly larger than a tube of chapstick. I'm guessing a receiver of some type and a switch for the button cell batteries. Powered by 1.5 dc. Nothing fancy, just to turn on and off the power.
