HOME Projector for cell phone or smartphone

Fun and easy that anyone can do in 15-20 minutes. The projector does not cost me anything because the materials had already at home, in any case the things you need to build it are worthless. Its operation is simple, Smartphone light travels through the lens increases the image on a wall. Getting it is as simple as doing.

Here is the interface used to connect the parallel port of the computer:
