Does anyone have any favorite text (or links) on this topic that they would like to add to the wiki? I'm sure that this is a question that will come up in the next few months.

Phil, I have pictures of mine that can be used. I may can come up with some suggestions for hooking them to the controller. Such as using DC jacks for the connections.

This is the instructions I followed to build mine.

That's pretty neat. I may look into doing that since I am switching over my host computer to a VIA miniITX board with a PicoPSU. Do you have to connect the grounds between that power supply and the computer's power supply at the controller?

Last year I drilled two holes in a PCI cover plate and bought two DC plugs from Radio Shack. I then took a molex extension cable and cut off the male end. From there it was simple to wire the +5v side to one DC jack and the +12v to the other DC jack. This allowed me power my Olsen 595 and my Belkin from the PC with minimal mess.

I would repeat some of the warnings in the wikihow article that Wayne J mentions. I would also add a pinout of a power supply drive connector, in case people want to use a PSU without cutting it open.

Need Help!!

I like the idea of using a PC PS to power my Grinch boards. I salvaged a PS model DPS-200D from an old computer. It turned on before I took the unit apart, but I can't get the proper output voltage now.
Red wire = .8V should be +5V
Yellow = 1.765V should be +12V

There are 3 other wires Blue, Orange, & White. Individually I have connected these to Red and then Yellow hoping to trigger a high, no luck. Same procedure to ground, no luck. There is no +12V at the cooling fan either.

Any suggestions?? Other than tossing it ???

Sounds like it's not turning on. Did you ground pin 14 of the 20 pin molex connector with a wire? If that works, replace the wire with a switch so you can turn it on and off.
