This is a simple mood light I built out of a mood and in just one day. It consists of a flexible coolant hose which has a WS2812B string + a pure white LED string in it. The base is black acrylic glass and glue. The animations are run on a Arduino Nano via FastLED library.
It turned out to be suprisingly difficult to get the LED strings in the already formed hoose. Pro tip: Straighten the hose, pull the string through with a vacuum cleaner and only then bend it into shape. Works a treat.
