Simple Transmitter/Reciever

[quantum]

I want to build a circuit so that with a push of a button, the reciever gets the signal from the transmitter, that transfers to a transducer. Just like a TV remote except I only want one button, and have it be radio frequency transport.
Example: I have my transimitter with the one button triggering, and the reciever which triggers a light bulb to go on. With a push of a button, the light turns on. Just something similiar to that.
If there is a circuit that has multiple triggering/channels, I wouldn't mind, I could modify it.j The range can be at least 20-30 feet min.
It can work in any frequency.
Please ask me for more information.
Just a simple circuit remember. ;D :D

i've done that kind of device wich is built from simple AM transmitter/receiver pair and used simple pulse relay in it.
details coming later...

wow that was quite similar to my project.. anyway I think this is similar to the details you have described:

Thanks for the website, what I want to do is to attach a reciever to my radio control helicopter so I can drop small items from above :D. I think I just might take apart a cheap remotely comtroled car and take it from there.

wow that's so cool!! how about drop a handful of black colored rounded object? heheh.. seems like a war zone :P
