ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************
I just learned yesterday, from a silly little book on how to make spy
gadgets with homemade materials (I wasn't in a postion to note title
or author), that if you take a pocket radio, tune it to some static
at the top of the AM dial, with the volume turned up, and hold or
mount a pocket calculator in front of it (switched on so as to create
a lil EM field), you can create a crude metal detector. Waving a
piece of metal between the two will make the radio go "woooo-eeeeeee-
ooooo!"
I know there was some discussion of this recently and don't recall
this solution being mentioned.
Forgiveness, please, if it was.
