DIY 3D Printed Zoetrope
(AdaFruit blog) A zoetrope is a device that produces the illusion of motion by rapidly spinning a series of static images. It is a classic invention with ancient roots and has gone through many iterations over the years. The littleBits team thought it would put their own “spin” on the zoetrope using littleBits and 3D printed parts. For this project, the circuit was relatively simple. It has a DC motor and three bright LEDs controlled by a pulse. The team also used a button in combination with a latch in order to be able to turn it off and on.
The DC motor sits in a custom 3D printed vertical mount so that it can stand up on its side. A large chipboard disc with 30 3D printed figures sits on top of the DC motor via another 3D printed connector. To make the animated figures they used 30 frames from a 3D animation file on Blender’s tutorial page. The whole contraption sits inside a dark box that has two small holes for viewing.
