[GreenKeys] Learning electronics

[tony j. podrasky]

Hey John;

I know the thread is off-topic but I think that it won't get
out of hand, and it could encourage some young ones into the
electronics field.

My thought is to either get them to each build a crystal radio
or for the instructor to build one in front of them.

That was the first thing I built - and that's about as close to
"magic" as you can get: look - the thing has ALMOST NOTHING in
it and it receives radio!

And it was cheap to build!

And, once the kids build it, then the next thing is to make an
amplifier (couple of transistors/caps/resistors/speaker) so you
can listen to it with your friends.

Then, morph it into a regenerative receiver - and add the shortwave
bands.

You'll see soon enough which kid is drawn to the love of electronics.

73,
W6ESE - tony
