You need a carton box, a big magnifying glass, cell-phone.
A cell-phone we place into the box, and the magnifying glass will be as an object-glass. Darken the inside of the box, insert a magnifying glass in the one end and put your smartphone (cell-phone) inside the box.

If projecting image from the object-glass is upside down, don't worry!!! Just manage how to turn the image on your cell-phone.
Close the cover! Turn down the light!
