I hadn't considered the heat and effect on computers - this is a problem. Thanks for that info. Somehow I have to make it on a smaller scale, and I had hopes of running it constant.....

I'd also like to hit you up about what you described as a "lightwave recorder". I'm about as smart in optics as I am electricity. What is the most practical way for a novice to convert light into sound? A hobby kit, perhaps?

Thanks,

Keith


I think Ramsey electronics made a kit but it is rather expensive for what you need. There is still a Google cache of an artice I wrote on the subjects back in 2006-2007. The photos may be missing. Let me know if you have any questons. If you can find a very bright plasma globe a modified recorder can pick up the random variations of the light. Best if the globe is DC powered.

Google "experimental recording techniques using phototransistor"
