“A twinkly star PCB ornament.
I’ve designed this tiny twinkly star for JLCPCB’s Christmas decorations design challenge, but I only got to order & assemble it now, so I’ve repurposed it as a wearable for now.
This was just a fun and quick project, so it’s super simple: the LEDs are controlled by an ATtiny13A microcontroller and powered by a 3V CR1225 battery. And it’s only 4x4cm wide!”
