Back in 1861, a Philadelphia man by the name of Coleman Sellers II filed a patent for one of his many inventions. The patent was for a device that he called the kinematoscope, which was able to take chronologically ordered photos and turn them into movies. By “movies” I don’t refer to the big screen, high-definition, 48-frame-per-second films that we are used to seeing today, but the kinematoscope was a major step in the history leading up to today’s modern-day film production.
For one man, named Markus Fischer, the modern technology of 3D printing has allowed him to turn back the clock and recreate his very own kinematoscope.
“The design is very simple and straightforward,” Fischer tells 3DPrint.com. “I use Blender, and cobbled together the first prototype basically using boxes and cylinders. You can turn virtually any video you have into a series of image cards for the kinematoscope. The video snippet should be a couple of seconds in length, and you will need 24 still images from it. [The kinematoscope] is a very primitive, yet effective way of getting moving pictures. It was the ancestor of movie projectors. Turn the hand crank, and it animates the contained image cards into an animation, using persistence of vision, similar to how a flip book works.”
The fabrication of the device consists of just four 3D printed parts: the handle, the frame, and two wheels. These parts, in addition to a 7-8mm diameter wooden rod, can be assembled to make this intriguing machine. Once assembled, Fischer recommends breaking your favorite film down into individual still images. The video should only be a couple seconds long, and 24 still images should be printed onto image cards and then attached to the rotating axis of the kinematoscope.
“There are several programs out there which can convert a video into a series of JPGs,” says Fischer. “The one I used is ‘Free Video to JPG Converter’ by DVDVideoSoft. Be careful, though: The installer is evil and tries to install adware. Use manual options and carefully unselect all optional things it tries to install.”
The software allows you to specify how many frames should be taken, and even which frames are used. Fischer recommends creating videos with a frame rate of less than 24 images per second, as this allows for more action to take place. Complete instructions on setting up the device can be found on Fischer’s website.
The way the kinematoscope works is that when the handle is turned, the frames (individual photos) rotate, creating a flip book-like effect. It’s a great way to store special moments that you would like to replay over and over again, and it also makes for the perfect gift to that special someone. Fischer has made the design files for his device available on Thingiverse for anyone to download and print themselves.
