This adorable “ghost” combines creative 3D printing with modern microcontroller technology. Inside, a RP2040 Zero brings the little figure to life, as its built-in RGB LED softly lights up the translucent body from within – perfect as a decorative light, mini gadget, or tech-inspired gift.

The eyes are the Reset and BootSelect Button.
