E-Books →Beer Can Crystal Radio How to make your own crystal radio using a beer can

A crystal radio is a small, simple radio receiver that enables you to listen to analogue AM radio using a crystal earpiece. This radio requires no batteries or power source!
Other books show you how to connect purchased components; this book will show you how to make some of your own components (variable capacitor and coil). To complete the radio, you'll also need to buy some parts; a diode, crystal earpiece, screw terminals and some wire. All other parts used are standard household items. A full parts list is included in the book.
Children should be supervised at all time during construction due to the use of scissors and a hot melt glue gun.
I'd love to see your finished radios! Please tweet them to me @iNimbleSloth
