How do crystal radios work? What’s the most rudimentary way a human could build one from scratch?
In: Technology
A great book on the topic of building radio components from scratch is “The Voice of the Crystal.”
“How To Build Working Radio Receiver Components Entirely From Scratch
In early 2000, I published my first book, entitled The Voice Of The Crystal, (or VOTC for short.) VOTC is a hands-on guide to building radio equipment from scratch. By “scratch,” I don’t mean store-bought components. Rather, this book describes the basic theory and construction of equipment from virtual garbage, i.e., hanks of wire, bits of metal, a magnet, a chunk of fool’s gold, a shoe polish tin, a cigarette lighter, etc.
The construction process is a lot of fun, and the end results are quite beautiful. This link will take you to the official web page of the VOTC, where you’ll find descriptive text, photos, critical reviews, and ordering information.”
