LED Spectrum Analyzer (Large)

[surf]

Starting my jukebox...

I would like to add a spectrum analyzer (a graph of lights that show the volume of each frequency)  as a light show on the front...

I've searched everywhere and, except for a tee shirt, I can't find too much info on this...

It needs to be about 15" wide and 20" tall, made with green, yellow and red LED's...

I saw the KeyWiz controller option, would this drive different frequencies or just random lights?


Just looking for ideas, thanks...

I will be looking at the frequency driven stuff shortly.  I have a start on it, but nothing is functional quite yet (I've only spent a few days on the software so far)

The LED-Wiz is currently using a couple of proprietary algorithms to get the animation and is not at all at random.  It's not the easiest thing to see in such a short clip, but when people start using the software I am working on, it will be a lot clearer

Kit is avalable as a start.  Just build the LED displays in a larger size.  Probably need a few drivers (easy circuit).

Two other possibilties depending on your skills.

This one is at AVRFreaks, I don't know if you need to register with them to see it.

This may work for you as well.
