Manual GIF Display Unit (Zoetrope)

LEARN about an early form of animation and discover why its creators might have welcomed an untimely demise! AMAZE your friends with a questionable choice of materials! WONDER how anyone thought this design was a good idea at first glance! (I'll admit, that one only applies to me.) Seriously, this is a functional Zoetrope. For some reason, the pioneers were really into these contraptions. After watching a short repeating animation for more than a second, you'll start to understand how desperate they must have been for entertainment in the 1880s. I've included some antique animations that I gathered, cleaned up, and resized to fit the medium version. To assemble this project, you'll need to print the following pieces: - Barrel upper - Barrel lower - Housing inner - Housing outer - Gear - Crank axle - Crank handle - Axle strap x 2 (just tap them in place with a hammer) - Wheel x 4 (or skip these if you're printing a small version, it won't make much difference) - Wheel axle x 4 (or skip these if you're printing a small version, it won't make much difference) You'll also need: - 4 screws, M3 size, 10mm or less, to hold the housing outer and inner together - 2 screws, M3 size, 5mm, to attach the crank handle to the crank axle - Cyanoacrylate glue to bond the gear to the crank axle, the barrel top and bottom together, and the wheel axles to the wheels. Make sure to glue the wheel axles slightly off-center (most of the axle on one side of the wheel) to match the thickness of the axle holders. Otherwise, the housing outer won't fit over them. Sand all rotating surfaces before assembling the project. Print out some strips, insert them into the barrel (note the clever posts that hold it in place!), and start spinning! The medium version is designed for a strip printable on 11 inches of paper (standard US size), while the large version is designed for a strip twice as long. Keep this in mind when deciding which to print. https://youtu.be/XwXohYdVC-4 https://youtu.be/6a2Ebe3oBe0 https://youtu.be/xulG1SR5sZA As with many previous projects, I'm grateful for Dr Jörg Janssen's excellent Getrieb.scad program that generated the gears. You can find it on Thingiverse!
