Pocket Projector

Finding myself with a few broken cameras made me wonder just what could be done with their all of the lenses they had inside.  a bit of testing showed that certain combinations made it relatively easy to project images from a film negative.  I rounded out the project by printing a reel of “film” on transparency paper, adding a light and a film advancement mechanism, and throwing the whole thing in an altoids tin.
