I'd like to get some recommendations from the list for a good introductory
electronics book for my 14 year-old son. He's interested in building an
intercom system (and other circuits) that he got off the Web, and I would
like something for him to read that will give him a good understanding of
how the circuit works. (For example, it uses the primary windings of a
120V:12V transformer as a coil.) TIA.
