Build a Camera Obscura Out of Cardboard
The camera obscura has been a tool for artists for hundreds of years. In this workshop, you build a camera obscura from scratch using discarded cardboard, paper bags, tape, glue, and tracing paper. You can use either a convex lens provided in the workshop or a pinhole poked in a sheet of aluminum foil to project a live image on a piece of paper. It's like making your own little live movie projector!

Before digital cameras came along, I loved photography, darkroom work, and photo technology. I also enjoyed craft work, so I made the working scale-model pinhole camera out of cardboard. More recently, I wanted to make a cargo box for my bicycle, customized just for my needs, so I made the detachable cargo box with cardboard slide lock.
