Try Google. You'll be surprised.

Hi,

Have you tried this site **broken link removed** and also Circuit - Circuits designed by David A. Johnson, P.E.

SODA

Best bet? for the easiest and cheapest solution, by a wireless doorbell or something. Or perhaps a cheap security system with a remote control, usually they can be had for <$10.

All you need to do then is modify it. Perhaps building one from scratch but RF is pretty tricky. So either way, I would buy the RF part as a 'module', prebuilt. Holtek make some which you can get off ebay.

Remote Control Encoder and Decoder ICs

No programming required, 1-4 channels. Making everythign completely from scratch will be more expensive, and a lot more hassle, these things are mass produced for so many markets.
