I've thought this to be a nice project, too, but I still get lost in the electronics part.

How would you generate the output wave?  Would you generate a BTC series of bits?  I was thinking once that somehow I could use a VCO, but I got hopelessly confused when searching for VCO's.  I didn't realize that there was such a range of frequencies.

Then I got sidetracked by trying to think how I could create a cell phone jammer to use when people get out-of-hand loud on the bus.  Then I moved to Finland and all my toys are still packed up.

Fun to still think about this stuff, though. (-:

Was thinking of using cadium sulfide cells (light resistors) in place of 
radio waves on a pic.
