any type of time anybody discovers a awesome method to screen in 3D — is there an uncool way? — we’re on board. Instructables individual [Gelstronic]’s technique includes an range of spinning props to play the game snake in 3D.
The helix screen consists of twelve props, exactly spaced as well as angled utilizing 3D-printed parts, each with twelve individually addressable LEDs. four manage groups of 36 LEDs are managed by the P8XBlade2 propeller microcontroller, as well as the resultant 17280 voxels per rotation are plenty to create an identifiable image.
In purchase to power the LEDs, [Gelstronic] utilized wireless charging coils typically utilized for cell phones, transferring 10 W of power to the helix array. A brushless motor keeps things spinning, while an Arduino controls speed as well as setting through an encoder. All the links to the code utilized are discovered on the job page, however we have the video of the screen in action is after the break.
There are some decidedly simpler methods to accomplish a volumetric display, in addition to some that feel ripped directly from a video game.
