[possibly off topic, but what isn't these days? :-)]
When I was a kid I had a book, I think it was called something like
"single transistor projects". As I recall it was full of lots of
simple circuits featuring a single transistor.
(or who knows, maybe it was 101 transistor project; I think I was
in 4th grade at the time - late '60s)
Thaere ahve been many such books. In the UK, a lot were published by
Babani Press (they now seem to sell Windows books as well :-(). Also
things like '50 simple LED projects', 'Simple projects using 7400 ICs',
etc (I've probanly mis-remembered thsoe titles).
anyway, one was a single transistor FM radio. I just remember it had a
single FET, a coil, a cap, some discreets. I think it told how to
wind the coil "in the air".
Presumanlu it used slope detection?
Does anyone remember such a book?
Yes, bitterly. Along with the manuals for the '150 in 1' electronics
kits. Many of the projects used 'clever tricks' and were not a all easy
to understand just why they worked, or how to debug them when they didn't
work.
