Halo Cortana NeoPixel Scarf #WearableWednesday


If you are a Halo fan you should definitely wrap yourself in this scarf. It’s another cool creation by caitlinsdad, who happens to be an Adafruit fan. The scarf makes use of our Cyber Falls Wig tutorial with a few changes, so it’s got a Trinket microcontroller and NeoPixel Strips. You’ll find details on the build on Instructables.

Caitlinsdad uses leftover scrap material to build the scarf and takes special care choosing the inside fabrics which hold the electronics. He uses a stiffer felt with sheer ribbon sandwiched on top, and then stitches channels to hold the NeoPixel strips in place. This helps to create the linear pattern for the light effects. 


What makes the scarf work is the addition of batting over the NeoPixel strips to add diffusion. They glow in a trail without being overly obvious. Notice that caitlinsdad tweaked the code to be blue instead of green for the LEDs. Here’s the video showing the finished pattern.

The scarf has a modern classy feel, and would lend itself well to knitting, so the black patterns would join seamlessly in the design. Even if you aren’t a Cortana lover, you might consider making a glowing green version of the scarf to imitate the raining code seen in The Matrix. If you are a Cortana lover, you might consider making our Cortana Costume. Wear the scarf by day and go all out Halo by night!
