More detailed description I've attached 3 pictures of the internals and labeled the important parts to make it easier to reference them. The view is from the bottom. A: Optics piece - Holds the laser and mirrors. Removable as one piece for easy adjustment. B: Original power supply and amp from...

Video! I made a video with my netbook's webcam. It gives you a bit of an idea of what it's like at least, but the quality isn't very good. Since I was using my netbook as both the music source and the recorder the audio got all screwed up when I had the speakers on, so even though you can hear...

:thanks: I don't have a video yet, but I'll give it a shot. I'll work on a post detailing the design sometime this week. I'm working all week so it might be a few days before I can find the time.

Version 3.0 I created a better version with my 50mw laser a while ago, and recently I made some changes to make it more portable. The original Y scanner wasn't very good since it jiggled the mirror a lot rather than just changing the angle along one axis. I hacked some components from a CD...

I wanted something more linked to the actual music than the mirror-shaker visualizer, and what's better than an oscilloscope for displaying AC signals? My dad happened to have a motor with a hexagonal mirror for barcode scanning which I used for the horizontal scanning. Unfortunately I couldn't...

Funny you should mention using a sweep for the x direction to make something scope-like... I'm actually typing up a post on doing exactly that. It should be done in a few minutes! UPDATE: The thread is up! Check it out! (it's in the laser shows category)

You can get a similar effect by stretching a piece of latex (a cut up latex glove works well) over a large speaker (like a woofer) and gluing a mirror a bit off-center. The latex doesn't just move up and down, it has some waves that travel around in it that cause the mirror to move in complex...
