Warning: I've not tested any of the following.They are just ideas!

Maybe this can be helpful, in desperate cases:
http://cgi.ebay.com/FPC-FFC-ZIF-BTB-flex-cable-adapter-converter-Z-/160502053503?pt=LH_DefaultDomain_0&hash=item255eaafa7f
Using the method described before (repairing torn FFCs) by Drewid, it'd be possible to cut an FCC in two, and make it longer using standard cables and two of those boards.Btw, i dont really know how the FCC is supposed to be attached to the board, but maybe somebody can figure it out (without involving duct tape :-D)

One problem i see with the board is that it looks a bit big.For a smaller board, a possibility is to "print" two custom pcb with the required number of pins and the required pitch.It seems there are methods to do PCB's at home (maybe this is also widely known, but i'm a newbie in DIY projects):

UK electronic components suppliers, I've no idea whether you need to set up an account there or whether you can just buy stuff though, they usually deal with businesses I think.

It seems they do have the cables, though you'll have to make sure of pitch and everything.

You can always get a wider cable and carefully cut off the wires you aren't using.   As long as the pitch is the same it will work.  You do need to cut the extra wires off, as they can act as an ariel and cause interference even if not connected. (Don't ask me how that works, but it's been seen before.) Roll Eyes


 If you go for one that's more than twice as wide and cut it down the middle then you have a backup cable as well.

If an FFC (Flat Flexible Cable) is the only thing you need then there is quite a lot of suppliers of these. This quite pretty inexpensive.  What DIY-beamer has that nobody else has is an "adapter" to "extend" the length of an ffc cable (because sometimes you cannot unplug one end and thus need to extend it instead).

The picture shown above is a typical FFC cable.

Over on Lumenlab they came up with a method for joining FFCs using a loose pcb socket of the correct size, and jamming two cables into it face to face.
