Building a simple crystal radio

“A crystal radio is the distilled essence of a radio. It has very few parts, it needs no batteries or other power source, and it can be built in a short time out of things you can find around the house. The reason a crystal radio does not need any batteries is the amazing capabilities of the human ear.”
