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...
