Yes, I made a pocket (assuming you have big pockets) 32 line mechanical TV
and I am wondering if it is possible to down-convert UK PAL signals so
that
I can watch some TV or DVDs on it for a laugh.
It's certainly possible, using something along the lines
of the commercially-available scaler/controller devices
used in the "front ends" of LCD monitors - although I'm
guessing that most of these will have a problem going
down to a 32-line format. If all you wanted to do was
a demo, it would probably be best to capture your
PAL video (or from whatever source), downcovert it
via a PC, and store the resulting horrible-looking
32-line video onto a USB stick or something, and let
the "pocket TV" run off THAT. Let's say you shoot
for a 48 x 32 pixel image; even at a byte per pixel
(more than enough for this sort of thing), each frame
only takes 1536 byes, so just a 32 MB stick would
store 15 minutes of video, uncompressed, at 25
frames/sec.
