Christmas Tree with Individually-Controlled LEDs: OCD Lightsystem

by Lambert Varias

We see geeky Christmas trees every year – in fact I became a fan of Technabob because of a Christmas tree post! – and 2012 is no different. But this Christmas tree’s nerd side isn’t obvious. At least not until it lights up.

While Olivier St-Martin Cormier has committed the mortal sin of taking a vertical video, we’ll forgive him for that because a) he has an awesome name  and b) his Christmas tree is equipped with 404 LEDs that are individually-controlled by an STM32 microcontroller. Olivier chose to make the LEDs blink in sync with Christmas music: “The computer plays the music and processes the sync track for the lights and send the state of the tree to the stm32 over Bluetooth. The PC-side controller has a web interface, so the whole tree can be controlled from any browser (PC/phone/tablet).”

Sadly his video won’t play on mobile devices, so you’ll have to use your imagination. Imagine a desktop computer then play the video on that one.

Olivier’s not yet done with the lights and says he’ll add more animations. He should just create animations for every holiday.
