Hello makers, it’s maker moekoe!
Today I wanna show you how to build a real LED dice based on six PCBs and 54 LEDs in total. Next to its inner gyroscopic sensor which can detect movement and dice position, the cube comes with an ESP8285-01F which is the smallest WiFi MCU I know so far. The MCU dimensions are just 10 by 12 millimeters. Every single PCB has dimensions of 25 by 25 millimeters and contains nine WS2812-2020 mini LED pixel. Next to the controller there is a 150mAh Lipo battery and a charging circuit inside the dice. But more on this later…
If you are searching for an even smaller cube, then check out the first version which I have created on my website. It is casted in epoxy resin!”
