Instructions
Lazzor it, try to fit it together, it has to be snug, but some sanding may be needed. Fix the shutter (tear drop thing) on with a screw and place a piece of card or metal with a pin hole in the middle behind the big hole.
In a dark room, put in some paper, close it up, seal it with electrical tape and get shooting. It should take a few seconds for each shot if you are outside. I think.
