WiFi Christmas Tree

Based on an old IKEA JULEN I created a WiFi enabled Christmas tree!


The JULEN tree is at least 10 years old, probably older and has been sitting around in storage without seeing much use. The 10W halogen + 2 W AC motor and ancient AC/AC transformer was a major reason. By using some WS2812B pixels and a Spark Core it can now be controlled from anywhere with an Internet connection and uses at most a fifth of the power!
