All the parts you need for the Portable Crystal Radio project, except for the cardboard box (the one we ship the kit in might work in a pinch, but it's a little smaller than ideal). You get 60 feet of 22 gauge magnet wire, a variable capacitor, a germanium diode, and a piezoelectric earphone.
Volume discount on 10 and 100 radio kits.
