ok maybe not the most challanging circut but I know nothing about creating circuits. what I want to do is run high brightness led's ( think along the lines of the laser led thing and you get the idea ) in a sound to light circuit 3 band if poss ( bass, midrange, treble) it is for a plex cube case to turn it into a sort of mini disco. thanks in advance
Color Organ I personally do not have a circuit for you, but it's called a color organ. You can find a number of kits online. They typically have relay outputs to switch lights on and off, and trimmer pots to adjust the trigger frequencies. Hope this helps.
Then the Quasar kit is just what you need, 12V operation and runs lots of leds. Instead of soldering them to the board, extend them on wires to wherever you want.
