Laser Harp - a more simpler thought. Help?
> Maybe you've seen (and i think you have) the LASER HARP project on the net, well i wanted to build something similar to that but using more simpler and i hope more cheaper components and parts.
> I plan on using ARDUINO for this project. About the Laser part of the project, i plan on using a simple laser pointer placed to point upward then aligned on top of it would be a photo-diode.
> the Laser pointer and the photo-diode will act as the "Strings" to the Harp, and there will be 8 of this for the 8 notes.
> So what do you think? oh and some advice on what speaker or speakers i can use for this, but i'm hoping to use only one speaker to produce all of the eight note.
> Hope you guys can give your thoughts about this... tnx XD
