Laser Scanner made from 2 broken HDDs

The idea came from Spaceflakes (http://www.spaceflakes.de/index.php?index=691), but I cut away the useless parts of the HDDs. I also added a TDA7374 amplifier (2 x 20 Watt), a TDA1524 volume/balance/bass/treble control, constant-current source with LM317, red laser diode from an old dvd-burner and a power supply (all build by my own *proud* ;-P ) and putted it into an Teko AUS23 case.
