When I was a boy, the local branch of the public library had an 1890's book
titled "Harper's Electrical Book for Boys" (IIRC). It showed how to make
everything from telephones to dynamos and lead-acid secondary cells and
carbon-arc lamps. It had directions that said things like "Go to a
blacksmith's shop and have him fabricate the following part" or "Oil of
Vitriol can often be obtained from your local illuminating gasworks."
I really liked that book, even though I never built anything from
it--blacksmiths were in short supply at the time--and I never did find my
local gasworks. I wonder if electronics will get to the point of some
young lad wondering where on earch one would find a 74LS00 or 2N2222 or
1N914 or even "hookup wire".
