Book excerpt: Harness the energy contained in radio waves to build AM crystal radios. Crystal radios are self-powered devices that do not require external power sources such as batteries. Although these radios are easy to build, using only a few electronic components, designing efficient crystal radios requires a fundamental understanding of the electric and magnetic fields, antennas, and basic circuit analysis - all topics covered in this book.
