From the project
PixelPine: a 7 cm PCB Christmas tree with 240 charlieplexed LEDs and a personality (KiCad, simulator, firmware sizing, docs)
KTE Project 1 · design-for-manufacture study · rev A · 2026-09-23
A chubby, cute, 70 mm tall PCB tree covered in 240 warm-white 0603 LEDs on a 2.12 mm grid. The LEDs are charlieplexed on 16 pins of a $0.13 Puya PY32F003 (Cortex-M0+, 64 KB flash) with software PWM. It runs from USB-C and slots into a PCB stand fin. The tree is a character, Pine, whose job is showing light shows. He's bad at it: he daydreams, naps, gets grumpy and gets excited to show you things. You interact with him through the capacitive star, which senses hover, tap, pet, press, a front-and-back squeeze and tickles. Landed…
