I’ve been working on a new OctoPrint system for my 3D printer, and as part of this project I made some nice flashy individually addressable LEDs for the sides of the enclosure to show the print status. The full project page is coming soon, but I just had to give you guys a sneak peek at the LEDs. These are WS2812 style individually addressible LEDs, controlled by an OctoPrint plugin on the Raspberry Pi, along with a perf board PCB I soldered to power and level-shift them.
