I've been invited to become a contributor to the Adafruit Learning Center -- Adafruit's online shop is where I buy most of the supplies for all the light-up costumes I've been making lately.
Adafruit's tutorial style is right up my alley. They have a good number of beginner-friendly projects and a lot of the guides focus on LED wearables and cosplay. The firewalker shoes and sparkle skirt tutorials are what got me all excited and interested in making LED costumes in the first place, and the Arduino lessons and project ideas made it actually possible. I've opened up a whole new world of fun and learned so much this past year and I'm super excited and grateful to be able to contribute to the site that got me here.
My first tutorial was just published yesterday: Animated Neopixel Glow Fur Scarf
Check it out. It's a pretty easy project -- beginner level sewing and beginner level soldering, with copy-and-paste-able Arduino code that I made pretty easy to customize. I'm extremely proud of it.
Let me know if you make one!
