1) A rectangular box

For better idea on how the projector works, hav a luk at the diagram...(that is the top view)
I hope that u all had understood the diagram and it wont be hard for ya'll to make it without my detailed explanations....;D
After you hav completed, keep your mobile upside down and point the projector towards the white screen.
If you see a blurr image.....try to focus by moving the mobile forward or backward
Make sure that the box gets fully sealed......and the light should not escape from anywhere except through the magnifying glass.
For best result , project it in a dark room......the more darker be the room, the more better will be the projection...
U can make in the basic way as well...see second diagram (top view).....bt image projected will be inverted!! thats y i added mirror for projecting original image...,
