Skipping down...

My plan was to stick a laser on that arm, run a sine wave audio signal into the armature coil, point it at a spinning mirror, aim the reflected beam at a projection screen and it should produce the image of the waveform.

It took a bit of trial and error, as always, but I finally arrived at a design that works great.
So sit back, relax, and watch the creation of a Laser Oscillograph on my workbench.

That's pretty cool!:) I never knew how Hard Drives actually worked. And I'm surprised at how easy it is to display an wave form with just Smoke and Mirrors;) He mentions in the Video, using True RTA to generate his Audio Signals. It's a Software Based, Real Time Analyzer (RTA). I looked it up and it has a limited use free version for Windows. You can get it here, http://trueaudio.com/. I searched in my Fedora 14's Package Manager for "RTA" and "Audio Spectrum Analyzer". As well as a few other similar searches. But, I couldn't find any RTA Software. I'm pretty sure that I have seen at least one in the Past. But, I couldn't find it today. Still, it would be worth a look, if you run Linux, like me. I put some other Linux Audio Apps Links Below...
