After hearing about this from Tony Allgood and finally getting the chance to do the MIDI interface. I just had to see this awesome creation from Martin and Tracy Frankcom.
When he offered to bring it over to my house I didn't need asking twice. What Martin brought was not at all what I imagined.
It was this huge mass of power supply, industrial laser, galvo and laser receiving receptable (the goblet shaped thing covered in tin foil).
N.B Galvo is the galvanometer which is a moving coil on one or more pivots with a mirror to reflect the laser.
powered up and running
Beams hitting the ceiling and passing through into upstairs ( only kidding )
Tonys scanning interface and photo detector amplifer gubbins.
Harp running prior to interface being added.
Harp all boxed up and running
