Icosahedron Glows With The Best Of Them

Glowables come in all shapes and sizes, and we’re always keen to see the multitude of different ways hackers find to put great masses of LEDs to good use. [cabrera.101] wanted to get in on the action, and whipped up a rather flashy icosahedron.

The build uses high-density 144-LED-per-meter strips for the edges, with 60-LED-per-meter strips used for the tubes that connect to the stainless steel ball in the centre. An Arduino Mega controls the Neopixel strips, with the wiring carefully planned out to ensure all LEDs have adequate power and signal to operate correctly. Not one to skimp on the juice, [cabrera.101] outfitted the rig with a 5V, 60A power supply – something that would have seemed ridiculous in 1992, but barely raises an eyebrow today.

It’s a build that would make a perfect whatchamacallit for a science fiction film. The reflections of the edge lights on the central sphere are particularly scintilliating. If you’re new to the realm of glowables, it’s easy to start – there are plenty of tools to help, too. Video after the break.
