I have been thinking of ideas to add to my second build. One of the ideas, is to have everything in a separate dedicated box on the ground and run everything to the mounted projector using only one plug. I believe another member on the forums has mentioned this as a design feature, however I could not find any examples of it being achieved. This would save tons of space on the inside of the projector, and it could be shrunk to only envelope the light path and the LCD. This way I could run a single cord with everything needed for the LCD and light in one plug. I mean everything too: Power to the LCD, the LVDS connection for the controller to panel, and even the wires for the bulb. I know the LVDS connection can theoretically be a max of 20 to 30 ft. I'm planning on a much more manageable 10 to 15ft. cord.

Now I plan on using the 575w HMI bulb in my projector and I know that the leads to the bulb are relatively high voltage compared to the low-voltage lines of the signal wires. The concern I have is whether or not the high voltage lines would cause interference with the signal lines.

I've searched the internet and found a possibility for such a problem:

These connections seem like a great option that could accommodate both the high voltage and the signal. My questions to yall is if you think these would be overkill? If so, do you think running all the wires through say... a salvaged printer parallel port would work?

You cant extend the bulb lead coming from the igniter beyond a few feet (like 2 think) because of the several Kilovolt pulse it takes to start the bulb. All of this is doable if you were to run the cable powering the igniter in the mega cable and keep the igniter next to the bulb. The only thing is this puts you at 2 high current high voltage lines for the igniter, and one for ground. I would say the cable you linked to is about right if you were to do it this way, only it looks to only have 2 beefy connections when 3 are needed.

My 2 cents

EDIT: looks like those connections are available with more than 2 big pins. I would use that over a printer cable. If you did use a printer cable, you would need a separate connector for bulb power (a 4 pin molex comes to mind).
