Experiments with audio

[Draco]

yeah that's what i want todo but i lack the programing todo anything with arduino unless some one shares their code, i would like to have it change colors or make other shapes and patterns on it's own with audio input. I had only intended to it to be green only, hence the older laser, when i can get some good aluminium some of the other lasers will be reused on that project, it will keep the blue and green lasers but i only have one working red diode laser, i love the single mode diodes for the smaller stuff, i compared the blues i have and love the beam shape on the single mode blue over the PLTB450B even though that is a lot more power

My main system in my living room is only audio controlled at the moment and what i do is send stereo audio to a minidsp 2X4 http://www.minidsp.com/products/mini...2-x-in-4-x-out and this allows me some control of the audio and then that is sent to a pioneer 20 watt car amp that has a balanced output (BTL) in this case for both channels, that drives two GS310 series open loop galvo to display a Lissajous display on the wall or celling , i have allways wanted to tray and do more with it and get a live rather then a programmed display, i am going to experiment with blanking and that clock display as well, i use mine all time and with in the last week i added a single mode blue laser to it so i can get different colors from it, here is a picture of the prototype

I really wish i had more knowledge of programming to get the effects from the posted videos but hey that's why i am here is try and learn this stuff. adding distortion and messing with the phase also can cause some neat effects.
I would not want to do this with my main galvo's that are closed loop unless i realy limit the audio spectrum. they over heat with normal audio, the GS series don't have that problem but have a hard time above 500hz.
I want to try and introduce this type of stuff to a friend of mine that likes the lighting effects but i think the best he has is a color organ he built him self.

Cool. I am aware of that DSP, I knkwknow Anthony Rouget the developer in Hong. Kong
