Laser Harp

You may or may not have seen a laser harp but if you haven't here's a video of a laser harp.

I was wondering if a laser harp can use the whole color spectrum instead of one color (EX: The least visible laser color of the color spectrum is the low note, and the brightest laser of the color spectrum is the high note.)

Sure, and it would make detection even easier. Although, the laser harp concept itself is quite old ... even before 405nm lasers, so using multiple wavelengths was kind of impractical at the time.

Look, I'm interested to laser harps as well, and I discovered this brand.
The laser harps are with two colors and one model can drive ILDA projectors. I think it can have all the colors.
Please, have a look

the laser harps are really rugged.
Perhaps you can ask more information directly to them.
What do you think?

Not at all, Anselm.

I'm just trying to find some real instrument as the other ones here and I've read this topic making my intervention.
For several years I tried to find something to build. Some kit, some valid project.
In internet I found several of them but also several "craps" that, for one reason or another, they don't work properly. They are just interesting experimental things but totally far away from my goal: to have an instrument that works without spending a lot of money.
I'm still convinced that everybody needs something good as I do, and I suggested this because it's the only one that convinces me.

I don't find anything wrong on it or anything wronger than link/questions written by "thecaptaindantheman".
