Anyone who has listened to more than two episodes of this program knows that I’m about as weird and geeky as they come. I’m a sucker for science and nature, and in spite of the fact that as a kid I would have rather looked for turtles and snakes in the vacant lots around our town than play sports, a fact that led to more than a few schoolyard brawls, my passion and curiosity have never left me—and hopefully, never will.

One of the best things I ever built, one of the most magical, was something called a crystal radio. And listen: if you have a young person in your life, pay attention—this is a great project to do together.

The very best resource I’ve found online about crystal radios is maintained by Professor David Goldenberg at the University of Utah. You can find his page at https://goldenberg.biology.utah.edu/fun.shtml.
