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.
Assembling the GRINCH should be fairly easy for most hobbyists.  The following sequence of steps is by no means the only way to do this.  It is simply a suggested order of events to achieve the desired goal.


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.

Board Assembly

Assembling the GRINCH should be fairly easy for most hobbyists. The following sequence of steps is by no means the only way to do this. It is simply a suggested order of events to achieve the desired goal.


  • Start by checking the PCB over for any production faults. Ensure that none of the tracks are shorted or open and that all holes are clear.


  • Install the four 0.1uF capacitors (PN# 581-SA105E104Z). These capacitors have no polarity to worry about.


  • Install the power LED (PN# 604-WP7104GC). The LED must be oriented correctly, if your LED has a flat side then match that to the overlay on the PCB. If not, then the shorter lead of the LED is the cathode and will go in the square solder pad.
  • Install the power LED resistor (PN# 660-CF1/4C471J). Make sure that the resistor has a value of 470ohms (yellow/violet/brown/gold stripes). The resistor has no polarity to worry about.


  • Install the power connector at J2 (PN# 538-70543-0001). The square pad signifies the +5 VDC connection.
  • Install the 2 pin vertical header at J1 (PN# 538-22-03-2021).


  • Install the four 24 pin IC sockets (PN# 571-3902618). The sockets must be all aligned in the same direction with pin 1 of each socket aligned with the square solder pad. Another way to verify that you installed them correctly is that the notch on the top of each socket will be toward the RJ45 IN/OUT connections.


  • Install the 18 RJ45 jack sockets (PN# 571-5202514). Due to minor variations in manufacturing, some RJ45 sockets are a tighter fit than others. Care should be taken to ensure that the pins are aligned first before applying too much pressure to seat the locking lugs through the board.


  • Install the ICs into the IC sockets. Ensure that pin 1 of the IC is aligned with pin 1 of the socket. Can be verified by noting that the notch on the IC is aligned with the notch on the socket.

CONGATULATIONS! You have finished your GRINCH controller board.
