Beer Can Crystal Radio: How to make your own crystal radio using a beer can

This book shows you how to make your own crystal radio using a beer can, toilet roll tube, cardboard, aluminium kitchen foil, wire and a few components. Full step by step instructions are given along with photographs to show you what to do.
A crystal radio is a small simple radio receiver that enables you to listen to analogue AM radio using a crystal ear piece. The radio requires no batteries and is not plugged into the mains!
Other books simply show you how to connect together purchased components; this book will show you how to make some of your own components (variable capacitor and coil).
Please note that to build the radio you will need to purchase a diode, crystal earpiece, screw terminals and some wire form a suitable electronics component supplier or ebay :) . All other materials used are standard household items.
Children should be supervised during construction due to the use of scissors and glue gun.

I'd love to see your finished radios! Please tweet them to me @bighead_org_uk
