No problem. Yes, those are 6" cables
Sorry about your cable situation. I guess you could string together 2 6"s, or maybe 2 6"s and add in a 3". I've heard that if you get too long, though, it may not work (because the signals are so fast and susceptible to interference or something?).

Also, regarding that OHP, make sure that you can fit a full 9" *12" object on it, as on many OHP's, the corners of the fresnel are cut off, making your image not square. Sorry, that was a really bad explanation. LOL

I might get away with 6" cables, does the panel sit face down on the ohp or up, not sure because of the mirrors, then I'll know how to position the boards before I attach the extender. Hope that makes sence, stupid question I know!

I believe in most of the OHP diagrams I've seen, the bottom board sits at an angle (in other words, not perpendicular to the LCD panel, but not straight out from the bottom either. kind of like:

The two back?slashes representing the bottom controller board. I don't see why you couldn't have it perpendicular to the board, however. Although, maybe that might put too much strain on those fragile connecting cables. You'd probably have to reinforce it really nice if you did that.

I, personally, use a box, and have my board perpendicular to the panel. This helps me with airflow, and also shortens the needed length of the ffc cable.

Hi Milihpen,
This is the stage I'm in, as you know this is the backof the board, to the left is the ribbon I have to extend.
I bought another OHP, it has a stage of 11.5x11.5 way better than the one I took back, it's a 3000 lumin-2bulb.
I also ordered the cables you suggested, just gotta wait now!

Hope the .jpg shows up.

Hey pacificnw.

Your image doesn't appear to be working...dunno why exactly.

That 11.5*11.5 might crop your image a tad, but maybe not. probably wouldn't look too bad if it did. I guess you'll have to try.

On another note, hopefully someone more knowledgeable responds to this, as I don't have that much expertise in OHP's, but I believe 3,000 lumens may be too weak for a projector. The average 400w mh puts out around 30,000 lumens, but then again, a lot of that is lost before it even reaches the first fresnel. I guess you'll have to try and see if it's bright enough.

Milihpen,
I recieved the cables and connectors the ones you sent me the part numbers for, thanks again, they are the right ones.
How did you get 2 ribbons in one connector, how did you rig it!

Not easily. I ended up having to take out that little clasp that you pull out to put the cable in, and push back in to hold it in place. With that gone, I had enough room for both cables (you might have to wiggle them a bit (gently), but they'll eventually be seated securely). Then, to keep them from slipping out, I hot-glued the two cables together about an inch above the clasp. That kept them from wiggling, and pretty much held them in place.

Not the best option, but unfortunately, Mouser doesn't carry the optimal connector (I believe it's the "vertical" one, but not sure) anymore.
