I agree.

After fifty years of learning and being involved with many different projects, there is nothing wrong with self learning.

Every once in a while it benefits everyone to sit down and review what they have been taught to see if the the understanding has changed.

When I did so a few years ago I came up with a solution to Einstein's Unified Field Theory that explains many issues that conventional physics has failed to solve.

I had to google fox hole radio, but totally agree, it can be a great start. From my perspective a crystal radio is the single childhood project I could probably attribute to continuing to want to experiment with electronics.

Kids today still get a fascination hearing a radio they have made (some of the kits need an engineer nearby during assembly, I appreciate this isn't possible for schoolteachers as easily. I tried a ZX2051 kit with some kids).

The diode could be a schottky diode, but the capacitor is a bit of a problem (tuning caps are hard to find locally nowadays, although aliexpress is always an option) so the air core inductor could be adjustable instead. Crystal earphones are still available.
