I’ve always been attracted toward “retro” informaiton sources.
One of the weirdest things I’ve ever discovered is: oftentimes, older texts do a better job explaining the technologies. For one thing, they tend not to implicitly treat the real world as a pale shadow of the mathematical models. There’s someting just conceptually ‘off” about starting from (garbled) descriptions of Bohr’s atomic model and only getting to observable (and thus verifiable) real-world phenomena such as magnetism, conductors/insulators etc. “downstream”
Quite frankly, a much better approach is one which recapitulates — at least conceptually — the sort of observations which culminated in what we can do with electricity/electronics/computers, etc.
That’s where “the boy electrician” comes in.
Quite frankly, as I said: it’s a hell of a book:
Not only does it recapitulate (in abbreviated form) the broad outlines of how human knowledge advanced in regard to magnetism/electricity/electronics, it also contains a myriad of designs which (in principle) would allow someone with the right tools/supplies to do the experiments, and/or build the devices.
The order of presentation is as follows:
- Magnetism and magnets
- Static electricity
- Static electricity machines
- Voltaic cells and batteries
- Electromagnetism and magnetic induction
- Electrical units
- Wires and accessories
- Electrical measuring instruments
- Bells, burglar alarms and annunciators
- Microphones and telephones
- Induction coils
- Wireless telegraphy
- Racio recieving sets
- An experimental “wireless” telephone
- Electric motors
- An electric railway
- Miniature lighting
- Miscelaneous electrical apparatus
I mean, seriously: there’s even a section on winding your own resistors.
