Here is a tutorial I found at Instrucables (which is a great site by the way) on how to make a Video Projector for your iPod without using any external power. Enjoy!
Intro:
Make an IPod Video Projector - video powered by Metacafe
Step 1:
The idea is simple, Focus the light from your iPod onto a nearby screen by means of lenses and mirrors.
Step 2:
Making prototypes is fast and easy using cardboard and a glue gun. A layer of black tape and that Apple sticker makes for a nice look.
Step 3:
In order to see anything it must be dark in the room.
Ok, I know that it wasn't really that great a tutorial but the idea is fantastic and if anyone has a working one I would love to here from you.
