- Soldering iron and associated paraphernalia
- Heat gun (a hair dryer will not work, nor will a lighter)
- Hot glue gun and glue sticks
- Sewing machine and accoutrements
- Scissors, needlenose pliers, wire cutters
- Foam wig head (notice how this is the only item that won’t cut, pinch, stab or or burn you)
- NeoPixel LED strips - 30 LED strips use less power, 60 LED strips are glowier!
- Trinket microcontroller and “Small Tin” Perma Proto board
3 x AA battery case w/switch (lasts longer!) OR 3XAAA battery case w/switch (slightly smaller)
- Stranded (not solid) copper wire, 24 to 20 gauge, three different colors
- Clear heat-shrink tube — 1/2" diameter before shrinking
- Tubular crinoline ribbon
- “Do rag” head scarf
- Elastic or fabric ribbon
- Small cable ties
- Craft foam (optional)
Not all of these parts are available from Adafruit…some detective work will be required. Read through the whole guide before committing to anything…maybe you’ll come up with substitutions for a different design or different assembly techniques. This is not a complete step-by-step how-to so much as an idea showcase.
Gemma has only three output pins for controlling NeoPixels. Our example code uses all five output pins on the Trinket, so you would need to adapt the number of LED dreads and how many connect to each pin.
