ok. this is great basic knowledge of electricity hookup etc. BUT the components since the book was written have progressed sooooo much that this is basically useless.
if someone could tell me of a book that actually explains how to hook up, let's say 20 miniature led lights to a battery powered 'box' that's operated by a switch would be great.
