Starting monitor rotation project
raph:
Ah, interesting.
I have a possible neat surprise coming for a marquee monitor, which may also be using a non-standard power solution; it arrives Saturday, whereupon I will know more about what I'll be doing for power across the cab...
DaOld Man:
I was waiting for the guys who have used those servos to rotate to answer your question, but why cant you just use your computer power supply?
raph:
Well, I wasn't sure if it was right -- none of the build photos I saw seemed to do it that way, and like I said, I am not electrically adept. I currently have a regular cased computer in there, and might swap it out...
What would you do, splice a red wire for 5v?

Yes, Red wire is +5VDC and the black wire beside it is ground. (Yellow wire is +12 VDC, if you need 12 volts for anything).
If it were me, Id buy one of those "Y" connectors that plug into your computers IDE power plug (white molex with 4 wires), then hack into it, that way if it dont work or you change your mind, just unplug it.
You could also leave a blank expansion slot cover out to allow the wires to exit the case. But I would wrap some tape around them right where they exit, to keep the metal edge from rubbing the wire, it could eventually wear through the rubber on the wire and could short out on down the road.
raph:
Yeah, thanks.
The marquee monitor that arrives on Saturday is actually a cut down LCD used in a slot machine, that I picked up on eBay. It has VGA and DVI in, and is coming with its own power supply and cables, so I might be able to grab the power from there instead... there's a shorter distance to travel from the marquee to the monitor than from the computer to the monitor, actually. I'll know more when it gets here, I haven't actually seen the harness yet.
