I’m not sure how well a flex PCB will work for an LED-studded mbius strip, but let’s find out. Mbius flex is a single-sided ;) flexible PCB (made from double-sided parts) with an Atmega 328p microcontroller and 60x 0603 LEDs designed for the Hackaday Flex PCB contest. It fits within a 13 sq cm total board area, so it can be manufactured using the contest’s free PCBs to the best 60 entries. I couldn’t wait, so I ordered a set of three from OshPark on my own dime, and this is the result.”
