Ceiling Projection

Post by Kurt_ » Sun Sep 20, 2009 2:04 pm

Okay, so I had an idea that I think would be amazing...ly difficult.

I want to turn my ceiling in to a second monitor for my PC. I have 1 foot of height I can sacrifice, and my room is about 10 feet squared.

My current idea is to mount a projector on to my existing ceiling, create some light scaffolding, and project on to a large angled mirror that bounces the light 90 degrees on to a sheet, which will be my "new" ceiling.

The problem with that is it would only work for a small section of the ceiling, and I thought it would be cool if the entire thing was a rear-projection screen.


Any ideas / work-arounds? The goal is to have a screen that spans most or all of the ceiling, it does not need to use projections. All ideas or thoughts welcome.

that would be crazy. are you saying that you're so lazy that you don't want to have to get out of bed to use the computer? :lol: just kidding.

I can't think of any way besides lowering the sheet further. And there's no way to widen the output on the projector?

You may get lucky and find a lens that will do it, but with only one foot of space from the cailing, you still won't be getting a large or visible, even, picure I'm sure. Why don't you put the projector on the floor against a wall aimed at the ceiling, and then adjust the rotation and the keysone to be perfect? Would be soooo much easier.

But way less cooler. The image doesn't have to be perfect, it's going to be mainly used for winamp visualizations.

Projector + Giant Mirror + Sheet seems the most logical, but the sheet would have to be stretched tight around a frame, which could not be projected through.

Oh, I see what you are doing now. Your problem is in only one foot, the projector will not have space to make a very large image to project onto the mirror.

why don't you figure out a way to raise and lower the large frame so that when you're not using it it's up, but then lower it into position for use?

You would have to have the lens distort the picture a LOT to make it fit right at that sharp of an angle. You'd also have to find a projector that supports rear-projection mode and has a bulb bright enough to make a useful picture on the back of the sheet (or get an old rear-projection TV screen and use that).

It would probably just be easier to mount an LCD to your ceiling.

You seem to be unable to grasp the concept that there are items in between my floor and ceiling. :P
