Now that my Arduino MIDI Footcontroller project is ready and working
it's time for me to start thinking about the next project.
Hmmm, well, actually i have already been thinking about it for quite some time.
I would like to make some kind of Laser Harp.
I searched here in the forum and in the internet, and there are many pages talking about it. I have read through many of them, but as a beginner i have some concerns about this project. I would greatly appreciate any advice you can give me...
So, for what i can gather, there are two main kinds of Laser Harps:
- those super cool made out of really powerful Lasers (you can see the "strings" and all);
- and those made out of weaker lasers, or even photosensors (you cannot see the "strings").
The thing is, and i think most of you will agree with me, what makes the laser harp cool, are those laser beams and the way you can interact with them to play some music.
That being said, i have also read in many pages that they can be very harmfull to your eyes. Hmmm, i kind of like my eyes, so i would rather if no harm would come to them!
My question is:What would be a good compromise between having some super-cool-laser-strings-awe-inspiring-harp and a safe-and-working-but-kind-of-boring harp?
I have NEVER worked with lasers and i also don't know many other alternative ways to do it. Some ideas that come to my mind (and that i have seen on other websites)
1) Super powerfull laser
2) Weaker laser (like a laser pointer) directed to a photo sensor <--- maybe the most doable?
3) photo sensors?
4) IR sensor?
5) distance sensors?
As i said before, the idea would be to built an Arduino based Laser Harp, as cool as possible, but keeping it safe (to build and to play)!
And all your inputs are very welcome.
