I put together plans to help a bunch of friends build their own LED scarves for Burning Man.
I was inspired by Liana B's LED Scarf; the Pixel Boa from Mood Hoops; Erin St Blaine's Animated Neopixel Glow Fur Scarf; and the wonderful folks with the FastLED library.
I've put together about 10 of these scarves and this was the focus of the July 2016 "Get Crafty (with electronics!)" class taught at my home in Long Beach.
