In which we commune with cables
The small screen driver board thing (technical jargon there) has a couple of
FFC (flat flexible cable) connectors. I take a macro pic of the cable to count the wires,
then spot the number printed on the board, each cable has 40 pins, that's a LOT of signals!
Each also has an additional fat earthing strip but then this monitor is earthed up the wazoo.
I don't think these earth strips will be strictly necessary but they'll be easy enough to extend
if I have to.
Ruler says cable is 20mm wide, even my boneheaded math says that’s
0.5mm pitch.
Here's a chance for me to sing the praises of another of those DIY projector
sites that I've come across in my researches. This is the excellent www.diy-Beamer.com an
Austrian site (though the site is also viewable in English and French). These guys do a
bundle of an FFC cable plus a double ended connector, which make the extension of those 40 ways
super easy. Being Germanic these guys are efficient and friendly and do a whole bunch of
FFCs in a range of lengths, pitches and widths. If I get round to building a projector I'll
be back there again.
The FFCs have a small clip holding them in, in this case its a
latch that lifts up, on the connectors it’s a wedge thing that slides out forwards by 1mm, easy
either way just with a fingernail. Make sure the cables are lined up, signal A going down wire
B can kill a screen according to rumours, but it shouldn’t be a problem if you’re careful
Cost so far £64.98
