There are many plans for DIY video projectors on the net: Easy DIY iPod projector, $6 Ipod Nano Projector, DIY iPod Video Projector – Requires no Power or Disassembly of the iPod, Super Sleek iPod or Other Device Video Projector and Make an iPod Video Projector. This is a good opportunity to build a simple optics project and learn a little about lenses and focal points. This would be a great demo or project for a middle school science class. And, there’s never anything wrong with breaking out the duct tape and hot glue gun to build something from scratch that does something useful and fun. I haven’t build any if the projects I listed on the beginning of this article, but I have played with the similar ideas years ago.
