Some more books that might interest you, one old, the other 2 modern.

The old one is 'Harper's Electricity Book for Boys'. It describes making cells (primary and lead-acid rechargeable), switches, bells, telephones, induction coils, etc from scratch.

The modern ones are 'Voice of the Crystal' and 'Instruments of Amplfication'. The first one describes making all the components for a crystal set from scratch. Coil, variable capactor, detector, headphones. The only 'electrical' thing you have to get is wire. The second book is similar, but covers making (albeit poor quality and short life) diode and triode valves and transistors.

There were also some articles in the American magazines 'Radiocraft' and 'Radio & Television News' (the second being the successor to the first) on making transistors using the crystal from a germanium diode and 2 cats whiskers.
