i what to strech my camcorder lcd 100 feet but ?

[David Askari]

i bough this jvc broken tape camcorder with flip out lcd. i am using
it as a survalience camera but the lcd is conected by a ribon with 5
to 10 conducters. if it were wires, i would just extend them, but
what to do with a ribbon, is there any thing that will chane it to
wire and back on the other side or other products. i taken the camera
appart cause when i bought it, it was water logged for a while which
i dried and did some lime away cleaning and actually it worked like
new except for the tape which they pried out before giveing me the
camera.

You should be able to attach a wire to each wire in the ribbon and then
connect them back in the same order at the other end.

Ribbon cable is just wire with the insulation connected together; or it's a
piece of plastic with the 'wires' (conductors) printed directly on it. In
any case it's just wire. You can solder to it if you're careful. Just cut
in half and carefully solder to the traces (in the case of 'printed'
ribbon), or strip and solder the wires (for stranded/solid wire ribbon). An
alternative would be to desolder and remove the headers which connect the
ribbon to the circuit board, and solder your 100' cable directly.

As to whether you can actually extend the signal path out to 100', I have no
idea. My guess is that if it's possible at all, there will be 'some' signal
degradation, at the very least. How much is hard to guess.

I suggest you might have a problem doing that: The link between the camera
and the LCD may well be a high speed digital databus, which if you try
and extend it to more than its current length, may stop working.

How far were you thinking of separating the LCD from the camera? Did you
say 100 feet? I'm guessing that's not going to work.

The older CRT-viewfinder camcorders are better for this hacking, IMO,
because the connections to the viewfinder are usually 0v, 5v, Composite
video -- which is very easy to extend and adapt.

Can you get a "video out" from the camcorder and then run that (via some
reasonable 75ohm coax) your 100 feet?

With an exact model number, someone might be able to check the circuit
diagram and advise better.

Mike.

hey thanks for the idea about the crt viewfinder, i was caught up with
the lcd and i can,t solder on printed tape conducters. The viewfinder
the crt one is regular wires. yes i can do av out which i have done
with telophone wire up to 400 feet for audio and video but i wanted to
have a separate moniter. i guess the viewfinder can put into a slide
viewer or such to look like the 2 inch lcd and b and w is ok. i have
a feeling that you are right about all that high speed data, i tried
extending a bw quickcam a mere six feet and got odd behavior.

I think it's unlikely any of these approaches will produce a useful
picture extended to 100 feet unless proper shielded 75 ohm coax is used
for the video signals. These were designed to have almost no distance
between the video source and viewfinder, be it an LCD or CRT.

OK, so identify which is ground/Ov, find what voltage it runs the CRT and
driver electronics at (maybe 5v) and find the composite video line. That's
the 3 important wires!

If you are going 100 feet, then use some reasonable, thin, coax for the
composite video line. If you are sending power over the 100 feet, bear in
mind the module will draw a few ma (one I use like this is about 100ma) and
you might get a voltage drop over the cable. If in doubt, send 12v and
regulate it down at the far end with a 7805 or something similar.

yes i can do av out which i have done

.... and connect that av out to the composite feed to the CRT module. Done!

Remember the CRT module will have some nice high voltages in ... try and id
the wiring without opening it ...

have a separate moniter. i guess the viewfinder can put into a slide

That's one option, have a play with some convex lenses (as magnifying
glasses or as a simple 2 lens "telescope") and see what you come up with.

OK, I practice some of the suggestions on another camcorder. I

extended the crt that had printed wire as opposed to regular wire.
(sony handy cam 8). I took of the crt and unpluged the printed wire
and unsodered the conector (six points). I solder 6 feet of computer
data in between the crt and conector and and pluged the printed
conector ito that and it worked. The solder is not easy. The
manifiers work. Bottom line a lcd is practical way to go. I
disconect the crt cause I use these bad tape camera for survalievce
and heat might be a factor
