Hari Wiguna has created a hand soldered 4x4x4 RGB LED cube that is about the size of a quarter!
The World’s Tiniest RGB LED Cube
Hari posted on Google Plus:
It is insanely tiny! [..] I could not believe they could drill a hole that small and plate it through.
Design files and code are on GitHub: 122-Worlds_Tiniest_LED_Cube
For more details, checkout the project page on Hackaday.io:
Hand soldered 4x4x4 RGB LED cube. Uses 2.7mm x 3.4mm SMD RGB LEDs.
– The cube itself is less than 1″x1″x1″ on a slightly larger custom designed PCB.
– 64 SMD (Surface Mounted Device) common anode RGB LEDs.
– All driven by an Arduino Nano (WITHOUT any shift registers)
