Homemade Pinhole Video Camera

Constructing your own pinhole version of a video camera is a bit similar to a still version. You will need a sturdy box that includes specific components inside. You will also use an actual roll of 35 millimeter film to take the pictures, instead of photo paper. Keep in mind that this type of camera can only take "silent pictures" as long as the length of the film roll.

Construction

    You need a metal box that is about 5-1/2 by 3-1/2 inches. Using an electric drill and bit, carefully drill a pinhole into the very center of the box's lid. The dimension of this hole depends on the depth of the box and the distance from which you are planning to film. Drill another hole into the top of the box near one of its sides; this hole is for the dowel stick and needs to be the stick's exact circumference. Insert the dowel into the hole and make sure it touches bottom inside the box. It only needs to stick a couple of inches out of the top hole; trim it to a good length for you. It may actually help to stabilize the dowel by drilling another hole in the bottom and inserting the stick through it as well. Open up the box and create a compartment inside it opposite the dowel. To make it, cut and glue pieces of wood or plastic (always wear goggles and a breathing mask when cutting plastic) inside the box. These pieces should be separated just enough to snugly fit a roll of 35 millimeter film in between them.

Use

    Fit a roll of film into the compartment inside the camera, centering it so the film will line up along the pinhole lens. Pull out the tab end of the film, wrap it across the dowel and turn the stick until it is securely wrapped. Keep in mind, though, that the more film you wrap around the stick now, the less you have to record with. Close the lid on the box and cover the pinhole by taping a small piece of plastic, cardboard or opaque paper over it. When you are ready to film, turn the dowel to roll the film and lift the cover off the pin. Once an entire roll has been used, you will need to keep the camera closed and the pinhole covered until you can get it into a pitch black room. Once inside the darkness, open up the camera and cut the film off the roll so you can load it onto a developing roll and into the tank for developing.
