The Voice of the Crystal How to build working radio receiver components entirely from scratch

Tom Lindsay is a whiz on wireless (but useless on steam), which is why we sold his radio books. Whilst this is not his, Tom recommends it highly and I can see why - indeed I can more or less understand them!

This may have something to do with his approach being as much mechanical as electrical - although there are some horrible equations and formulae at the back of the book.The project here involves the construction of amplifiers, microphonic relays, transformers etc., all from scratch. What really interests me about this book is not so much the fact they tell you how to make a radio and listen to sounds from the other side of the world, but the intellectual curiosity and pig-headedness that the author used to make the parts, when everyone told him it couldn’t be done.

Stirs up the brain box in a very satisfying manner! 185 & 297 pages respectively, full of drawings diagrams and photographs. Paperbacks, published by the author.
