Reconstructing RGB LED Cubes: Hardware Engineer DIY's world's most beautiful and shining gift

When [Freddy] faced challenge, when he made a different gift for a colleague with a hobby, he set a plan. He is not making a display with an existing LED panel, but a cube is made. However, it is not only a common cube on the market, but a miniature desktop size, no fun, LED cubes that do not lack function or performance. Recently, we have been studying a large number of beautiful RGB cubes, but there is no size and functionality in line with our expectations. The key components here are tiny but a reasonable RGB LED, with a side size of 1 mm. But I finally found an even said the smallest "2020" set WS2812 and APA102S in the world. Pushing his layout function to the maximum, squeezing each LED into a grid, and its element is less than 1 mm, thereby generating 64 LED panels, only 16mm x 16mm panel (test point and controller are mounted on the back). Each of these four-layer PCB constituting the complete cube includes an amazing 950mm long, which means that the entire cube has nearly 6 meters of traces! Be How do you supply electricity for small devices that do not have a clear position? Of course, you can pass the wireless QI coil. Don't let the cube itself exceed the power [Freddy] try to set a suitable power supply on the back of the coil. Please pay attention to the rice particles in the left below! The only disadvantage here is the processor - diagonal suspension in the cube on the microemplate - cannot reprogram. I hope that future versions can support programming. Here is the video of RGB LED cubes, I hope you like this interesting project. Be Copyright statement: HackADAY authorization, Circuit City original translation video, declined!
