low-cost audio waveform display doubles as space heater

For those of you who on a budget who need to visualize audio
waveforms, check out the following link.

All we need to do is figure out how to make the equivalent of a
horizontal sync circuit.

Might want to check with your local fire department first ...

Happy New Year!

I'm trying to think of the equivalent of a Fourier Transform lens for gas pressure, and make a spectrum analyzer out of it. -- Eric Jacobsen Minister of Algorithms Abineau Communications http://www.abineau.com

Maybe you could set it up like the basilar membrane in the ear, which does a spectrum analysis by having a physical resonance point that varies with frequency. I would love to have a gas grill with this feature; steaks take 20 minutes with Beethoven, 5 minutes with Bon Jovi. Bob

Attach it to a set of vibraphone resonator tubes? Richard Dobson
