DIY laser harp powered by a Raspberry Pi and RasPiO Duino

Not much detail on this, but it’s way too cool not to share. David Pride announced on Twitter that he has created a DIY laser harp. He uses a 50mW laser with a stepper motor to create beams of light and then LDR sensors detect beam breaks and the Pi plays a corresponding midi note. The whole thing is tied in to a RasPiO Duino board. You already know I hold the board in very high esteem, but this is the first time we’ve seen something this big and fantastical! Hopefully he’ll provide more details in a future blog. Here it is in action. Leave him a comment on the YouTube video if you like it!
