The Story of the DIY Ugly Christmas Sweater with Lights and Bluetooth Spirit Meter

Had a little fun with this one in Christmas story style, but you can go to 01:31 to skip straight to the build.

This DIY Christmas sweater has a fully functioning, Bluetooth-controllable Spirit Meter (or Clausometer for you maple syrup spaghetti eating ELF-lovers) and plenty of twinkle courtesy of around 35 RGB LED lights on the front and back. Power comes from a basic portable USB battery pack and connects to Bluetooth for control (courtesy of the ESP32 microcontroller for a brain).

I'm not an experienced sewer (haha sewer...) so hot glue was the MVP here.

Happy holidays and hope you enjoy!

The hoodie was from Michael's and the other decorations were picked up from a Dollar store. I used cotton balls in the video, but don't recommend them as they're not durable whatsoever -- use some other cotton fluff.
