This is what I have it sounding like - though it's a bit soft, turn it up and you can hear it: The laser harp is working! - YouTube It can move that sound octaves up and down and it's really easy to code, so I'm there - I figured I could expand it later, one problem at a time. :-) I think it...

I used this to make the sounds: GinSing - a synthesizer shield for the Arduino It's pretty nice and has a 1/4 output jack. It depends on how much flexibility in sound you need - for a hobbyist like me it's great, I'm just happily using the built in sounds. If you really want full control over...

Ooo that's nice and probably better than my variable light idea. :-) I have my harp playing two strings at a time now so that's an issue but ... well ... this is still a pretty sweet thing and I kind of like it! But then I think my requirements are a lot less stringent than Things - I'm just...

My laser is constantly on so I think that's not the issue ... though that makes me wonder if it'd become one if I go to a TTL laser? I've for the step width and time in external variables, so I've tinkered with those a lot to get where I am now. I didn't want it to sit on a beam TOO long, the...

For clarity - this is what I've seen that I'm trying for: Tetris Theme on Laser Harp - Theremin Hero LIVE! Finale - Gamecity 5 Nottingham - YouTube But then what is THIS? Laser Harp - Gary Numan / Avicii Mix (Practice Session) - YouTube Ignore the beginning - that's multiple beams combined...

I've been building a laser harp and am working on this same issue. I am using a continuous laser and I can confirm that's all that is needed, turning it on and off is probably better but adds a LOT of complexity. Here is what I have a continuous beam looking like in a stepper motor: The laser...
