i got this lcd from ebay for 28bucks just type in 2.5 inch lcd reverse monitor or something like that it needs to have the composite input (red yellow white plugs) if it only has the yellow one thats fine. so once you get it unscrew it and be very careful because the lcd is easy to break , take the metal case off the lcd and all the plastic filters until you can see through the screen(it will still be bury to see through) then place it infront of the fresnel lens (it should be upside down and backwards) when your picture is the right way on the wall, tape the screen on and you are done! now just put a lid on the box and stick the cables out the side of it

how do you connect the lcd to a computer?
I have bought a 2.5 inch lcd, a VGA to RCA converter box but the resolutions aren't compatible (2.5 inch lcd from ebay have resolutions of about 320*240 and VGA to RCA converter from ebay begins at resolution 800 * 600)

Do you have to use a 2.5 inch screen, or can you use a bigger one.

and also... will the resolution be like a real projector? i mean a ordinary one not a HD one.
The resolution will be the exact same resolution of the original LCD screen. Adding lenses and lights does not change the number of pixels on the screen. With that in mind, unless you get a HD screen, the image will be worse than a normal projector. But again, it all depends on the screen you start with.
