That's... pretty awesome, actually.
So if I remove the case/bezel to mount an LCD in something else (like an old TV set case), will it still work as before, or does the case have to keep OUT light as well as produce it for visibility?

That's why you buy a used one from garage/estate sales, craigslist, etc. assuming you don't have one lying around (usually with a defunct school name written across the side in Sharpie).
Buying one of them new just for this is moronic (as is buying a new monitor to take apart, in case you wanted to price those, too).

Well, when I posted, i thought these prices were pretty good, but the used projectiors are all under a hundred.
I made one of these a few years ago. Cost nothing and would have worked well except the smallest LCD ?I could find (14") was too big for my overhead projector.
Back in the 90s, when overhead projectors were still popular, you could get LCD panels that were intended to be used in this way. I ended up getting one of those on eBay for like 0 and got an overhead projector, and had a sweet 480p projection system for like 0. It was the envy of all the other grad students.
Ended up spending a shitton on bulbs though.
Which is to say I ended up getting this back in 2000, when they were really cheap (and I was a grad student).
