If you are looking to build an easy pinhole camera have a look at this one.
“Here’s my latest contraption which uses 35mm film to provide square images of 24 x 24mm. Using this size means that you can get up to 50 exposures on a standard roll of 36 exposure film. Now that’s what I call economy! The image edges suffer from distortion that gives a “Diana” quality to the pictures. In fact, the images look very “toy camera” like indeed, except that the pinhole allows some really good close ups due to the DOF of the pinhole.”
