Hacking Old Laptops Into DIY Projectors

LCD projectors are great to watch movies and to play games. Having tried them out ourselves in a few different settings, we can say that there's nothing quite like having your own home movie theater, especially when it includes one of these projectors. How about making your own?

While not a lot of people have the extra money to just go out and purchase one, a lot of people have old and broken laptops that are just accumulating dust. Once you've upgraded, a lot of them just become worthless, especially after 3-6 years.

That's why we really liked this hack we found on Lifehacker. This hack involves taking apart the screen of a laptop, sticking it onto a projector and using it to project stuff. The most important thing that you have to remember is that the projector generates quite a lot of heat. You have to cool it so that it doesn't melt the screen of your laptop. The screen should have its backlighting removed and it should be placed on spacers, not directly onto the surface of the projector.

This build will cost you $150 or less, which is pretty impressive for creating your own projector. You can fit an IR and UV filter onto your bulb to protect your laptop screen from yellowing. This is a sensible protection. This great idea comes from Randy Sarafan from Instructables.
