So you want to learn how to transmit sound using a laser? the implications are actually pretty good, you can send sound without having to use wires or cables, which means that theoretically you can send sound as far as the laser can reach. If that’s not cool, then I don’t know what is!

We actually tried to add several different lasers going all over the place to different places of the room, and when someone walked around it would actually keep the song from going off think of it as a giant human size DJ machine, I’m sure if you have enough time in your hands you can probably make a room full of these things and the people dancing make the song beat. Or some crazy gadget like that.

  • can we use photodiode or something like that (phototransistors) instead of solar cell?? please relpy
