Coobie V2 Is a Internet-Pushed 512-LED RGB Dice Show, Constructed by a Scholar Trio



BINUS College college students Michael Angelo Chandra, John Lukito, and Johevin Blesstowi have written a information to constructing your personal Espressif ESP32-based 8×8×8 RGB LED dice show: the Coobie V2.

“As of late, three-dimensional illustration (3D) is fashionable. 3D illustration might be present in cinemas, digital modelling, AR, and VR. We’re at present shifting in direction of a world the place the boundary of dimension is more and more being exceeded,” the group writes of its work. “The place the world has seen a masterful implementation of 3D show in drone swarm, we goal to develop a extra moveable, as mesmerizing and showy, albeit much less sharper, laymen-controllable 3D show within the type of Coobie V2, the web-controlled 8×8×8 RGB LED Dice.”

Because the title implies, this is not the primary Coobie. The unique mannequin, the scholars admit, had its issues: it was cumbersome, fragile, and had points with sign interference. Coobie V2, in contrast, is extra simply moveable, much less glitchy, and extra sturdy — and the devoted app used to regulate the unique dice has been changed by an online app, permitting for customized animations to be outlined and performed straight in-browser.

“We created this web site utilizing Subsequent.js and ThreeJS [and it] connects to the cloud backend,” the scholars clarify of the dice’s consumer interface. “This web site is an innovation by no means accomplished earlier than within the grand scheme of LED Dice[s]. By means of this web site, anybody can create their very own sample, animation, something they’ll consider that’s higher represented in 3D.”

When it comes to the {hardware}, the Coobie V2 is pushed by an Espressif ESP32-S3 microcontroller with a stage shifter, eight MOSFETs, 12 Shenzhen Sunmoon Micro SM16126D LED drivers, a shift register, a transistor array, 512 RGB LEDs, and a formidable 100 meters (round 328 toes) of copper wire, a bunch of PLA filament for 3D-printing jigs to type the dice, and “plenty of feminine and male [pin] headers.”

The total challenge is documented on Instructables, full with 3D print recordsdata for the jigs and hyperlinks to the supply code beneath an unspecified license.
