Herb Susmann led a fun Crystal Radio building class. Crystal radios use the energy from the radio wave itself to power the radio receiver, no other power source is required. This interesting design uses a wire large loop wound around wooden crossbracing as a resonator, it does not require an external antenna or a ground wire. The loop does need to be oriented towards the broadcast antenna. If you see a kid around town spinning slowly in place with something that looks like a weird wire kite on their shoulder, chances are good that they’ve got a crystal radio and they’re trying to catch a wave!
