The Ultimate do-it-yourself
There are plenty of guides around the web showing you how to build a projector for your smartphone, usually housing the phone inside a shoe box with a magnifying glass at one end in order to focus the image onto a wall. They're cheap and easy to do, and the resulting images are viewable, if a somewhat fuzzy and dim. The shoe box design leaves a lot to be desired however, so in this project video we will be making a well designed smartphone projector that stands head and shoulders above most others out there! It really is quite splendid.
