GRINCH Controller Assembly Instructions

Background

There are a myriad of computer based controller hardware available that will run under the Vixen software While Robert Jordan was working on his LEDTRIKs, a LED panel based display, he noted that the same driver IC chip could replace two different types of chips used on the Olsen 595 COOP board.

Robert’s aim was to come up with a circuit design for a controller that was smaller, cheaper, and easier to construct than the Olsen 595. He had to give it a name and decided on the ‘GRINCH’ after his favourite Christmas movie. The details of his prototype are detailed on the Computer Christmas website.

The GRINCH does what you expect it to do – it makes lights flash under control of Vixen. It does not have Channel LEDs, it does not dim lights, and it does not use PICs. The GRINCH does work and it is cheap!
