Turn Your Phone Into a Projector. Get an old shoe box cut a hole put a magnifying glass in it put your phone however close or far you want to make the picture on the wall big or small And watch whatever movie you want ;
Make your own projector using a shoe box, duct tape, magnifying glass, and your smart phone! That's crazy! A projector would be nice.If I made this and used it during an observation either I could save us a lot of money or get my own projector.
