Few people have heard of it, yet many consider John Blankenbaker's KENBAK-1 to be the first commercial personal computer.

DIY: Matchbox pinhole camera

Matchbox Pinhole

This little DIY camera is so simple that I might have to build one this weekend. It consists of little more than a matchbox with a pinhole shutter, a roll of 35mm film (you'll need an empty spare as a take-up reel) and some lightproof tape.

alspix says: "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."
