[sdiy] Listening and recording electromagnetic fields

I seem to remember reading somewhere that the sound of the lightsaber in the 
Starwars movies was created by waving an unshielded dynamic microphone near 
the deflection coils of an operating TV set.

Exactly!

This reminds me on the "Pocket Calculator" (Taschenrechner) song from 
Kraftwerk.

They also used the sounds of the old caluclators.
The good old Texas Instruments TI-30 made the Kraftwerk-Pocket Calculator 
sounds quite good.
No inductive coupling was needed, you could simply take a signal out of the 
keyboard matrix via a 47k resistor or so.

Ciao
Peter

That video made me smile - It's ironic that people are wanting to listen to 
and record these sounds, as Electronics Designers often tear their hair out 
trying to find ways to stop these pops, crackles and buzzes from finding 
their way into the audio outputs of products!

I guess one man's noise is another man's symphony! ;-)

-Richie,
