Gummy bear shaped mood lamp. I’d soldered together a 4x4 cube of multi-color (RGB) LEDs, but didn’t want to display them on their own. Using an Arduino board to control the cube, a program to cycle through colors was modified from an existing piece of code. The bear lamp was purchased in England and had been kicking about the house for ages. It didn’t have the right plug for the US, so was never used. I took it apart and replaced it with the slowly cycling mood lights. It’s really great to have around - super cute and relaxing effect.
