[…]In the third version I got a lot closer to the vision in my head. I designed some custom PCBs to mount addressable LEDs to instead of individually PWM-ing each Common-Cathode LED (I still have unplaced anger at whoever let me live so long without knowing about the WS2812). I was also able to use the SparkFun Qwiic Flex Glove Controller that I had designed after the failure of the second iteration. I sourced new fiber to test some neat audio-reactive and gesture-reactive code.
However, I had one major flaw: the LED modules I had were connected via Qwiic cables as I had this strange obsession with making the system solderless for easy repair out in the wild. This worked for a little bit, but some of the cables had a little bit less friction with their receptacles, so exuberant movements would promptly unplug things. Also, the cables would occasionally break from the connector after a lot of movement.
