Hi all, I'm looking to convert UK TV signal resolution down from 625 lines to 32 lines. Does anyone know of some off the shelf plans for such a beast? Thanks

Am I correct in assuming the signal is in PAL?
no, but I've got some software called aaplay that'll show video on a text display :)

to 32
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.Bob M.
Thanks, I'll give it a go.
