Two Lasers - One Board

just make sure the projectors share a proper earth ground before doing this.

What do you mean by a proper earth?
Here in the UK our mains lead comprise of Live, Neutral and Earth.
Are you saying that any linked projectors should also have another Earth?

A friend suggested that a Printer switch box would do the job just as well.
Merely rewire it so that all connections are always on.
He reckons that they work by merely switching the ground on/off anyways so it wouldn't take too much to hack one of these bad boys to provide a quick and neat solution to running several projectors from one card.

The bonus would be that you could run a single cable from the PC over to the lighting stand and then split the signal at that point (via the box) to several projectors.
Not being too techy I merely nodded and agreed with him.

Can anyone see a reason why this would not work?

I once had a 4-way parallel switch box, and it switched all 25 pins. Maybe the newer ones are wired like your friend said, but that old one I had certainly was not.

Besides, if you're going to have to buy a switch and then re-wire it, it seems that it would be easier to simply add a pass-through port on your projector. (Less money and roughly the same amount of work.)

I still say the simplest solution is to use a short length of ribbon cable and some IDC connectors. You put 3 connectors on the cable. One end plugs into the ILDA cable from the controller, and the other end plugs into one of your projectors. The middle connector is for the cable that will feed the second projector. No sweat, and you can build it in 3 minutes or less.

Nice find.

Looks exactly what I was after.
Fortunately a very nice man has offered to knock something similar up for me so yet another thread has a happy ending.


aaahhhhhhhhhh.......
