Sometime ago i had an idea in my mind about a DIY wireless link between, say, two MCUs. But the point is that i never tested it. I just wanted to know what you thought about it and if you think it could work (you are the electronic gurus after all :) )
It should work like this.
-Receiver has the antenna attached to the base of a darlington, and the signal received goes to the MCU (if not enough maybe i could make a bigger darlington, maybe three NPNs)
