New Versions of Old Tricks

Okay, so I re-invented the wheel a little bit. Some of you are going to laugh at the simplicity of my projects, but you have to admit that it's not bad for something so simple and cheap:

YouTube - Music Laser with Keyboard

well, your vid doesn't say anything about what it is?.... so, what is it?

looks like a spiro with a speaker galvo?

You can obtain a similar effect placing a third mirror on the path, and glueing it on a speaker .....

You can basically use different speakers and glueing systems, for obtain different effects and "shifting" ..... more robust ones are these small speakers used in "porters" (citophones), cause they are usually made with a plastic membrane, instead paper.

if you need few "shifting", you can just glue the mirror directly on the cone ..... if you want more "shifting", you can glue the mirror with silicone one end on the border of the cone support, and the other end on the cone ..... more the other end is near the center, more lever you get (this way it become inclinated, instead just displaced, and the optical lever principle do the rest )

I like the bluray on those gels

thanks for the feedback. it's actually more simple than some of your guesses. the description and comments of my youtube videos explain how it's done, and guitar string version links to a couple high-res photos. the guitar string version worked better before it got kinked from too high volume. i'll build another...

back to work for now....

guitar string was i think 18 mil and 2" long.

Long time ago I made a simular device. I cut a silicone cupcake cup so that it had a small area in the middle to glue the mirror on, and 4 legs to tie to the 4 mounting holes on the outside of the speaker. I used a cheap adjustable PC sub-woofer so I could control the volume and bass intensity. I screwed a small screw through the middle of the silicone cup, and hot glued the mirror on to that. Works really well. I'm actually am working on the same design, but am going to use a spiro instead of a direct flat beam to project on the mirror.
