[sdiy] Random Voltage Generation

[Grant Richter]

That is not that far out.

If you consider you could build a mechanical system (say pendulums with
magnets) record the movements onto computer, and then play them back at high
speed to shift the waveforms into the audio range.

There is probably tons of slow datalogging files that could be reformatted
to "fool" the computer in thinking it is an audio file.

I think someone tried that with a years worth of seismic data. And then
there was the "Earths Magnetic Field" record.
