Need help with a big project - will post an instructable when finished Answered

So what I'm trying to do is make a massive equalizer that will plug into my computer (or stereo, if anyone has any good ideas on how to tackle that) via USB and serve as an audio visualization on my wall. I'll be using a 4x8 piece of plywood to mount 450 LEDs to ( 30 columns of 15), building a frame, then screwing a 4x8 sheet of frosty plexiglass to, then another 4x8 sheet of plywood with 2 inch holes drilled out in the same 30x15 arrangement as the LEDs (do you follow? lol).

I'm pretty handy, so the drilling and everything isn't my problem. My problem is trying to figure out how to power 450 LEDs, put each on a I/O switch, and control those switches with my computer (I've read there are winamp plugins to deal with similar things, I wonder if they'll work with what I'm trying to do...)

I'd prefer to use USB to power my contraption, but unless I figure out how to utilize PlusPower, I don't think that's viable, and I don't really feel like burning out my power supply either.

These are the LEDs I'm using.

I'm considering wiring each column in parallel and using microprocessors as switches, but I haven't really gotten that far in my thought process, and I'm not sure if that's the best way to handle it anyways (plus I'd like to try to save some money by controlling it all through USB instead of investing in microprocessors).

So I've rambled off about as much info as I think is useful for those of you willing to help me with the logistics, if you have any questions at all feel free to email me at xslingshot@gmail.com

Thanks in advance,
Zach

Awesome! Now that I know what it's called I can just find one online instead of wasting the time coding one, lol...

. I think what you are describing is called a spectrum analyzer. Try searching for that.
