The great thing about holidays is that they always seem to require some shiny things. The modern version of shiny things seems to be LEDs and advances in technology being what they are, we now have amazing programmable LEDs. And programmable LEDs mean animated shiny things! Years ago, [wpqrek] made an LED ornament using discrete components. This year he revisited his ornament and decided to make a new, animated, RGB ornament.
[Wpqrek]’s build is based around five WS2812b strips connected to an Arduino Pro Mini. The ornament itself is a thick styrofoam ceiling tile cut into a star shape with a red-painted wooden frame. Decorated with baubles and stars, the LED strips start in the center and end up at each point in the star. With each strip connected in parallel to the Pro Mini, [wpqrek] used the Arduino Light Animation library to handle the animations.
[Wpqrek] says the result is too big for his tree, so he uses it as a stand-alone ornament. Perhaps using lighter materials would help — or getting a bigger tree! Check out the Arduino lighting controller or the Trompe-l’oeil Menorah for more holiday hacks.
