!! NOTE: Kinograph is a work in progress and is not intended for use in the field...yet. It works - but is limited by the DSLR's mechanical shutter, the need for mechanical improvements as well as software migration to a more robust platform. These and other issues are being solved by the community on the Kinograph forums. Please join us there.
This is a set of assembly instructions for the Kinograph (http://kinograph.cc), an open source film scanner for digitizing 35, 16, and 8mm film. This project is in active development and is in its very beginning stages. The v0.1 is the first released version and is considered experimental. Please visit the website for the most up-to-date information and to join the community to help improve the project.
While living and teaching in Jordan, I discovered a collection of 850 orphaned film canisters. With no financial support for their digitization and no equipment in Jordan to view the films, I decided to make a machine that could be built there with parts easily purchased online and with cameras that my students had available. The result is the Kinograph, which was made while I was a student at NYU's Interactive Telecommunications Program. More information the collection of films found in Jordan can be found here. I plan to return to Jordan with the Kinograph in 2014 to digitize the films and make them available online.
This scanner is made to work with consumer cameras such as a DSLR, micro-4/3, etc. The one requirement is that the camera you plan to use has a remote shutter cable. Here is an example. PLEASE NOTE that consumer cameras have mechanical shutters (that clicking noise you hear when you take a picture) that will wear out. If you use your camera to digitize large amounts of film, it will need repairing. As a reference, the Canon 5DmkII has a shutter life of ~300,000 shots. This means you could comfortably capture 200 minutes of film before repairing the shutter. Obviously, this is not ideal. Kinograph is an ongoing experiment and designs are in the works for a more robust camera system that does not require mechanical shutters.
Kinograph also comes with software which is discussed later in this Instructable. It too is going through constant development and the latest version can be found on Github.
The work currently being done on the project includes:
2. Design of separate 8mm capture machine and accompanying Kickstarter campaign.
3. Lab tests on an industrial version that uses a camera with a global shutter.
4. Building a community portal where users can share their progress and design changes.
5. Making a kit of parts and/or fully assembled Kinographs available for purchase.

The materials used in this build are suggestions. You could build the frame out of other materials, use different motors, etc. This build has been tested and works reliably.
Any item with a star next to it could be replaced with another part of your choice for a cheaper build. I chose to go with these parts because when I was building it, I didn't have a fully realized design yet and these 80-20 compatible pieces allowed flexibility and ease of ordering so I could get to the first build quickly and modify it from there. They're definitely overpriced and can be replaced with other parts but I have not had the time yet to try other parts. Let me know if you do!
