A big thanks to all who provided information and ideas on the "POW
Radio" project. FWIW, I learned a few things:
1. The razor blade radio was actually called the "Foxhole Radio." One
response explained that the "POW Radio" was really a 1-tube regen (that
may be the next class project if I can work up a circuit).
2. Gillette Blue Blades are still available, although not everywhere
(or in most places)
3. Any metal will do, preferably a little corroded. There is nothing
special about the "blue" razor blade.
4. The pencil point-on-rusty metal "diode" isn't exactly a real diode
and the radio doesn't work very well. I remember this as a kid when I
and my geek friends made a few of them.
Pacificon yielded a little crystal set kit that we're calling "Prototype
#1". We're going to use a 1N34A and do a little tap dance around the
razor blade issue in the introduction. The kids are organized in the
class into 7 groups, so current plan is to have each group build their
own radio. Troy (the teacher) says the kids are really excited about
the project. Stay tuned, I'll probably stick a web page out somewhere
with the results and some pictures.
