Front picture of the PCB I made. There are errors in the design, but nothing that prevents it from working without modification. I originally intended to put connectors where the CAT5 cable is soldered on now, but I made the holes too small... And what in the world are those huge green caps all over the place! Gah, ok, so I had them lying around in quantity at home...

Back of the board. Nice for a second-generation prototype, eh?

And here it is with the lid opened. You can see the two-controller board at the top (16 channels total) which is the real prototype. This one runs at the internal frequency of 4 Mhz, which allows a mere 32 levels of dimming. The PCB shown above used a 20 Mhz crystal, allowing an easy 256 levels of brightness.

Stacked triac boards. The boards are the TRIAC-4 boards from SimpleIO.com -- useful critters, too bad they're closing shop.
