Pinhole Camera

thingiverse

A miniature telescope has been devised, whereby a very small hole, or aperture, is drilled in one end of a long, light-tight box made of wood, which serves as the body of the camera. By adjusting the hole so that it corresponds with the size of a fine pin, and making its circumference absolutely round by cutting the surface at both sides for some little distance beyond it, you can create a surprisingly large image from a tiny spot.
