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.
