Here’s a good one: Building a very simple AM voice transmitter.
A while back I ordered the parts and made this one. For the simplicity, it works quite well (I didn’t get a chance to test the range, though). When you plug it into an audio source you have your own mini AM radio station. It makes for a nice, easy project for people interested in learing about electronics (or people who are just bored).

I think it would be far better if i could have seen the circuit composition of it !
