Cool LED Art - A Blinky LED Thing for JR Using a PIC

Checkout the Aurora 18×18 Kit and PCB with audio interface.

Do you suppose the firmware could be modified for a vectorscope/goniometer?

You'd need to MUX it one more time... they are muxing the three colors by 9 columns, but 18 rows of LEDs are all in parallel.

They also use pretty crude direct dive, with discrete buffers... I push serial data to driver/latches. While I only address 3x12 LEDs in my current piece., or 4x16 in that console meter I did.

Of course you can do anything with a micro but, that one only gets you part way there...and not very far down the path.

You know I never had one of those funky 70s-era "color organs."

Remember the old Radio Shack and Allied Electronics color organ kits?

I can stare at Winamp's visualization for hours so you can understand why I might be drawn like a moth to one of these things.

With RGB LEDS, just set up an X by Y matrix and make a color TV picture...

Or just buy a 60" monitor and run Winamp.

Looked like his kit required a lot of 0603 soldering.
