UPDATE: This kit is discontinued please see the new version, 8 Channel LED Controller v.3, the development files are still available to build this version.
As simple a circuit as can be. A 12F675 controls a high-power shift register, which in turn controls up to 48 LEDs at 20ma per, (~120mA per channel) in 8 channels(groups),
Software controlled patterns create seamless effects from group to group. With 4-state greyscale ( 4 states of LED of brightness ) a vast amount of patterns/effects are possible.
It was designed to go along with my 8"x8" 32 LED Infinity Mirrors.

A single momentary-pushbutton cycles through the programmed patterns. Comes loaded with 5 patterns, and the ability to add more through re-writing the firmware.
Kits, Including 32 LEDs, colors buyer's choice, can be bought from my store at www.ChromationSystems.com
More Updates and Info will be Posted to the 8 Channel LED Controller Webpage
