Lumiero Handheld Projector

LUMIERO is a small handheld 35mm projector I designed for a university course on "expanded cinema". It can handle up to 20m of film and uses a camera flash as lightsource(will be changed in future versions). With LUMIERO you as an artist are no longer bound to 24frames per second - you change the framerate simply by changing the speed in which you operate the crank.

The light will pulse once for every frame, eliminating the need for a mechanical shutter mechanism while ensuring nearly perfect synchronisation between light and film, if you manage to put the film in exactly the right spot, that is ;-)

Future versions might include a lightsound decoder for your beloved talkies, actually if someone wants to build one - go ahead ;-) the backplate should be able to fit an arduino for further experiementing.

This proof of concept still has some mechanical issues mainly with the geneva mechanism in different stages of projection, as well as no spooling mechanism so your film will end up on the floor.

Thanks to Mcinnes81, the pistol grip used here is a modified version of his design "Sony Action Cam pistol grip" at http://www.thingiverse.com/thing:153917

Thanks also to kellyegan, who created the original openScad file for the film-spools used "35mm film spool (variable sprockets)", find it at http://www.thingiverse.com/thing:28236.

Print instructions

• Basically cut the 2d parts with your laser, materials and thicknesses should be noted within the files.
• Print the rest with ABS on your 3d printer, then have fun assembling all the parts.
• You will also need a lot of M4 maggot screws, and a few M3 ones,
  also standard M3 screws and nuts as well as a few strong magnets, to keep the front part from falling of, I used 5x5mm cubic neodymiums.
• Also, if you want to use the film-gate included, you can put simple circular neodymium magnets on it to keep it in place.
