The Populist, a homemade 35mm pinhole camera made from cereal box cardboard, black duct tape, rubber bands and other household supplies.
This is mine, shown as it would be loaded with new film. Notice the ticker (a sliver of credit card plastic) positioned inside one of the top sprocket holes. As you wind the film (turn the dowel), you count eight clicks to advance to the next frame. To continue loading the film, you would cut off the leader and tape the film to the bit of lighter colored film on the take-up spool.
