Gang,

The Museum crew has become involved in the IEEE Engineering Mini-Academy 
program, an undertaking to inspire high-school students to a careers in 
engineering.  We'll be participating in February. One of our exercises 
is the assembly of a simple FM transmitter using one transistor, 
emphasizing the concept of "breadboarding.".



After assembly the kids get to attach their mobile device, and see how 
far away they can hear their favorite music.  We did a test run of this 
last evening, victimizing some 11th graders.  It was a notable success.

Now we need to gear up to produce about 10 kits.  Most of the parts are 
easily available on Ebay, directly out of China for almost no money, but 
we need some variable capacitors.  Something in the neighborhood of 
50-75 pF that's easily panel mounted, and has a 1/4" shaft.  Like these:



What's out there?

Al
