[sdiy] Re: sniffing

[Toby Paddock]

I've been doing some "recreational" H-field listening lately 
with a couple 5000 turn air core coils pointing 90 degrees 
apart for stereo. Put a couple diodes across to clamp spikes 
and a cap to block the "plug-in-power" from the minidisc mic
input.

It's pretty interesting to hear what AF fields are flyin' around.
Like in my car, there's the alternator, ignition, turn signals, 
break lights. No surprise. But I didn't expect to hear the 
alternators of the other cars.
