Homemade Projector Box

A decent homemade overhead projector?

Is there a simple (and cheap!) way to make an overhead projector for showing some transparency images on my wall? I figure all I’d really need is a light box underneath with a mirror and lens over it to project the image. Were could I find a lens to use (if this method would even work of course)? Would this produce clear images or would it be fuzzy?

those projectors had special lens on base, and the upper part had two lens’s. along with super brite projector lens.
I am willing to bet there are a lot of schools that have a storage room full of them.
