My homemade projector

The process is really simple. I happened to have a 17" LCD lying around, which was too big to fit on an overhead projector's "stage" properly. This was ok though because the printed circuit boards that control the LCD are connected by a ribbon cable and really can't be moved out of the way.

The paper around the projector protects against light pollution in the room. and there are two pieces of wood that raise the LCD off the stage. If put directly on, the heat from the light could heat up the LCD too much and darken the entire image. (That's bad.) The laptop I'm running it from currently is very old and only outputs at 1024x768. The LCD used in the project has 1280x1024 resolution. I'm sure that If I hooked it up to a better computer that the picture quality would be better.

I got the idea from here:

And they did an update that shows LCDs that are good for the project.

I used my 17" LCD because it was broken and I already had it, making my project free!

And to Doomfest, no it doesn't work in a lighted room (or at least my very well lighted basement).

Oh that is it. So simple pretty cool. Must try it.

The only thing I can see that is missing are fans.
Your not concerned about the display overheating?

Since I got most the stuff for free, and because it's not a permanent system, I'm not concerned about heat. I want to build a better one eventually, but I haven't gotten around to it yet. So yeah, I haven't had heat issues yet, and I'm not too concerned, even if it overheats and breaks the LCD.
