How to Make a Hunger Games Tech Scarf With Fire #WearableWednesday #Wearabletech #Arduino

Hunger Games Tech Scarf

Caitlinsdad, a long time Adafruit fan, strikes again with a hot scarf combining a few of my favorite things like Neopixels and Hunger Games. This is a hack to the Thermometer Scarf he already created for his daughter, and this time there is another layer to his creativity as he employs matrices for displaying flames, as well as text. Check out the video to see if you can figure out the meaning behind the numbers, flames and messaging.

Caitlinsdad is a great scavenger of parts and creates his matrices from leftover Neopixel LED strips he’s amassed over the years. With a bit of fiberfill for diffusion and some code from the FastLED library he creates amazing flames in the white section of the scarf. The bottom black section of the scarf displays temperature and humidity in another matrix, as well as an ominous message. It’s all powered with an Arduino Uno and a DHT22 sensor. The intricate wing on the scarf is actually crafted from pipe cleaners which have been hardened with glue, and if you look closely you’ll spy the Mockingjay symbol which was 3D printed from a file on Thingiverse.

There’s even more humor than usual in this new scarf Instructable by Caitlinsdad as he has declared this project a tribute to me. It’s true that I’ve been known to whirl in my Flora powered Hunger Games dress and I’ve even used Arduino for a project dealing with climate change. Like Caitlinsdad I have my share of leftover Neopixels and have used them for Halloween pumpkins and Christmas tree toppers. Anyway, I hope you are all inspired to grab some Neopixels and make your own scarf. The weather is getting wacky and we all need to be aware of the changes. In fact, it may be wise to add a datalogger to make sure the numbers get recorded and archived. Go forth makers. and may the odds be ever in your favor.
