Step 12: The Projector Lens

Picture of The Projector Lens
 
I was really lucky, because the projector lens I'm using has some sort of metal support, and the height was almost exactly with the centre of the LCD. All I had to do was drill a couple of holes to fit it to the wood.

hey newton, im trying to follow this instructable but i have a few questions.. firstly. i need some help with getting the lens, Ive currently got a alpex telephoto, but im not 100% sure that will work as it gives me tiny images, secondly, how far does the image have to travel to be the right size for the lens. ( mine is 3.5" LCD)

Two questions. Does it have to be a triplet lens or could a single lens work instead? And, Do you know how many X's magnification your lens is?

Hi there!
If by "side" projector lens you mean "slide" projector lens, the answer will be no. Sorry I tried b4 with a slide projector lens for this screen size and it didn't work.
