DIY XY Laser Projector

DIY Laser Projector build up in a Midi Tower chassis with two old Hard Disks (XY Axis). The green laser is a modified laserpointer (only 1 mW, but not so dangerous ;))with active fan cooling. Theres a red laser (4.9 mW) too, but not active. The laserdichro for mixing red and green to yellow is not working as i want. Laser is controlled by Ableton Live via audio signals. Music by me.

The laserpointer is connected to an universal ac power adapter at 3V. The green solid state laser have to be cooled, because it fastly warm up and will break if its not cooled. I put the laser into an old external aluminium hard drive case and connected an old pc-fan too.

I used the moving coils from the hard drives "read/write arm", connected these to an audio amp via audio cables. X-Axis to the right channel, Y-Axis to the left channel and controlling the Mirrors with an audio tool on my notebook while panning the audio signals from one to the other channel.

Very nice! I'm doing one, so.. What software are you using for the signals? Thanks

hey, nice built! Did you add something like a resistance spring / magnet to the HDD galvo? Since the two I extracted only have a weak positioning magnet which doesn´t reset the arm fast enough.

how'd you make this...
