A projector works by transmitting an image through a lens that is then viewed on a screen or some sort of flat surface. You can make a cheap projector from the LCD screen of a broken laptop and an overhead projector. You will also need a few tools commonly found around the house, but no special electronic or mechanical skills. Your cheap projector will project a video image, although the quality will not be equal to that of a projector using expensive optics and electronic components.

1. Place the laptop on a table. Open the lid. Remove the screws from below the hinge on the back of the laptop with the star screwdriver.

3. Pull the LCD screen assembly free from the body of the laptop and place it down on the table. Remove the screws surrounding the LCD screen assembly with the Phillips jeweler’s screwdriver.
