This Mystical LED Halloween Hood tutorial from Becky Stern is one of favorite Halloween guides from the vault.
Create glowing eyes for your costume! This project is ideal for any character with glowing eyes, like the Black Mage from Final Fantasy, Jawa from Star Wars, or Orko from He-Man. Two NeoPixel Jewels can appear any color or animating pattern, and they are driven by a GEMMA microcontroller powered by a 500mAh lipoly battery in a 3D printed pocket.
