WebI built my first ever crystal set when I was 9 years old, but that was a different world. We're going to build a 21st century style radio with all modern components which are relatively easy to obtain at your local electronics store or on the Internet. The radio is contained inside a Tic Tac box, and is called "The Nic Nac Tic Tac Radio". WebIf built from components, the connections can be made by twisting bared wire together, or made more secure with solder. Actual connectors, solderless or soldered, may also be used. In general, a crystal radio consists of: Coil of wire (a cardboard tube and fine gauge wire can be used) Capacitor, sometimes variable (tunable) my little shaver reviews
