Instructify

Rescue some technology from the trash and stretch your school’s supply budget with this cool project. Does your school have a busted laptop or a flat screen monitor bound for the dumpster? Hack-2-School, a site for design students, shows how you can combine the LCD screen with an old overhead projector to make a wall-filling video projector on the cheap (scroll down to get to the entry).

This project may be a little on the advanced side if you’re not of the handy persuasion - you’ll have to take the monitor apart to remove the LCD panel and cooling fan. But even if you haven’t picked up a screwdriver since high school wood shop, the video demonstration makes it look pretty doable. Just make sure you use it for educational purposes. –BILL FERRIS
