[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)
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".
Does anyone remember such a book?
I figure if anyone one would, it would be someone here...
seems like a fun thing to build now days with my son.
