The basic concept is that you create a switch with two electrically isolated pieces of conductive fabric that is closed by sticking a pin through both pieces. Materials Felt or other non-conductive fabric Conductive fabric Coin cell battery 2 LEDs Conductive thread Non-conductive thread Solder 2 snaps Tools Soldering iron Needle Scissors With a breadboard, alligator clips, 2 LEDs and a battery, set up the circuit and make sure everything is working as you would expect. The first step is to cut out 3 pieces of non-conductive (normal) felt in the shape of the doll and two identical squares of conductive material.

A pinhole camera is a camera where a tiny hole replaces the conventional glass lens. Light passes through this hole and an image is formed in the camera. The basic optical principle of the pinhole is known from ages. The ancient Greeks, for instance, used it for viewing eclipses safely. In the Middle Ages this technique was used to study projection of light. Pinhole pictures are not "poor". In its simplest form, a pinhole camera is a light-tight box with a pinhole at one end and film or photographic paper at the other.
