As the devices to record such formats become less accessible, so do the methods to view them. There still exist a large quantity of super 8mm film reels from the days when film was the preferred way to capture home movies and save memories. Even as the digital age continues to press forward and bring new technology into our lives, some people are finding the desire to use older analog formats. Vinyl, polaroid and super 8mm film are seeing a resurgence in usage. As one of these people who shot some super 8 film, I found the methods to view it very limiting. Finding a projector or digitizing it. The current services offering digitization don’t satisfy the needs of a casual hobby user; they are either too expensive or don’t provide sufficient resolution quality that is needed when working with film. The goal of this design is to create a device that can digitize super 8mm film. This device should at least meet all the specs of the professional models, and exceed the consumer models. Resolution, scan speed, reel size acceptance, flexible camera settings, weight and ease of use. Price will be the final determining factor in the product success if it meets all these criteria. The design of the device functions as follows; A motor gear turns a driven gear attached to a hub with an offset pin. The distance is the length of 1 frame of super 8mm film. Sitting on the offset pin is a metal claw that reaches horizontal and has 2 super 8mm film sprocket sized claws in it. A plastic piece fits the metal claw to the gear and down to the lower hub.
