I've been posting for quite a while now, in the CRT proj section.
My projector is now rebuilt, and I'm planning a serious installation in my next place.
Part of it is a custom-made (money IS an issue) motor-screen.
And since masking is cool...
My goal is to end up with something like the stewart vertical electriscreen electrimask ( http://www.stewartfilm.com/engineeri...ons/vesem.html
I managed to find the needed motors : http://www.elero.de/engl/produkt/rolladen/rolladen.htm
Next, I figure, I put two of these in the same box, one for the screen, one for the masks.
One kinda heavy tube at the bottom, and maybe tensioning.
Last thing : I'm gonna need a big drop-off black part at the top, since my window (behind the screen) is high.
What do you guys think ? Is this realistic ? What screen material should I choose (since my CRT is an oldie, I think 1.5 gain would be wise).
Ever built your own motor-screen ?
