Hey guys,A couple weeks ago, I was in Shenzhen, China for a hackathon and on the first day, we all used the one-day PCB fabrication to make PCB badges to wear during the event. I decided to go a little crazy and make some cool 3D alchemical-cosmological badges.It's 3 PCB's stacked on-top of each other that's connected using testpoints on each board. The innerboard has a 10 cent CH32V003 MCU that powers the WS2812B neopixels on the outer rings using the testpoints and shines through using exposed soldermask.If you have any questions about how the design works, feel free to let me know!

Could you build this?
No This is a physical hardware project involving 3D-stacked printed circuit board (PCB) design, electronics fabrication, and physical assembly.
What it would actually take: This project requires proficiency in EDA tools such as KiCad or Altium Designer to draft multi-layer schematics, trace routing, and artwork layer exports (Gerber files). Physical manufacturing requires PCB fabrication, pick-and-place component assembly, custom inter-board mechanical interconnects, and physical testing.
