i learned to make crystal radios with the following ingredients:
- a piece of wire tied to a water pipe
- the carbon rod out of a torch battery
- a razor blade
- a cheap earpiece
- another piece of wire sticky taped to my bedroom wall
i used to get into trouble listening to radio series and serials late at
night, like "Crime Doesn't Pay", so i learned to knock up one in 10
minutes, as they always got confiscated.
my vengeance was that i knocked off dad's razor blades!
criminally,
EL
