3D-printed Super Mario star twinkles atop the tree
Christmas trees normally have a star on top, and Super Mario famously becomes invincible when he grabs the star power-up. Naturally, for retro game enthusiasts, these two are begging to be united.
In this project, Doug Lenz (AKA “Freshanator”) did just that by morphing the Mario star into something that can be placed atop a tree, using a 3D-printed body and addressable WS2812B LEDs to provide the “twinkles.”
The unit is printed in yellow PLA, with a pair of black eyes glued on. Inside, LEDs are arranged near the tip of each of the star’s five points, which diffuse through the printed material.
Power is supplied by a Micro USB breakout, and the lighting is controlled via an Arduino Nano. The device runs on the “Fire2012” example program from the FastLED library, though Lenz may revisit its operation in the future.
