I have a couple of laptops laying around the hose, some still come on, but the screen is so dim that you can’t really make sense of the words anymore. Tinkernut came up with an awesome way to bring that computer back to life, he teaches you how to Make a cheap projector using an old laptop and an overhead projector.
To do this project you will need an old laptop or an LCD screen that you don’t mind tearing apart. You’ll also need an old overhead projector. This is just a basic tutorial, and is only meant to be built upon.
