    Hey there, I was thinking about making a wireless drum trigger. From my understanding so far, it sounds like it could be pretty easy, but I am a total noob, so I am not sure if this will work:

    It sounds like I could connect a piezo buzzer element to an oscillator (another piezo I guess?), and then to an antenna to make the transmitter. Without a battery somewhere I know this might be a pretty weak signal, but I only need it to go a few feet. Then I'd hook another antenna to another crystal of the same frequency, then to a diode, then to a mic cable connector.

    Is it that simple? Would the piezo i'm using for the trigger fry the crystal or anything?
