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

Awesome !!!
Oh My God! My wife and I were just talking about looking for one of these mirrors a couple of days ago. I had the image of these burned in my brain from childhood for some reason. I saw one as a child and have been amazed by them ever since. I know that is weird but hey, everyone has that childhood memory of something that amazed them as a child. Thanks for posting this and all your projects are great! Now I can make an awesome Coffee Table.
