I'm working on a laserharp for some months now.What? A what?
Okay, maybe I should explain first...
I like the music of the French electronic music pioneer Jean Michel Jarre. I visited lot's of his concerts (next sunday again in Belgium!), and his music inspired me often.
One of the most well-known gadgets Jarre uses in his shows is a musical instrument called a laserharp, like this one:
More picture of Jarre using a laserharp can be found on Google.
Years ago (over 15 years) I decided to build a laserharp myself.
So I built a simple laserharp with 10 red laserdiodes and some light dependant resistors, and that worked great! I could touch one of the beams and music came out of the speakers, produced by a Yamaha CS1x synthesizer I had back then.
I already used the ZX Spectrum to control the midi to the CS1x and read the sensors from the laserharp.
But I always wanted to make it better, more flexible, more like the harp Jarre uses himself, and with a more bright laser.
So some months ago I picked this project up again, as you can read here:

Also I am discussing some aspects on WoS:

I just finished a new interface with DAC and sensor input:
I only have to finish the software now that controls the midi output.
So this week or the next I must be able to play on my new laserharp again!
High-tech, but with a ZX Spectrum! ;)
