Hats Off Challenge LogoAdafruit and element14 present the GEMMA Hats Off Challenge! Let’s upgrade hats with the Adafruit GEMMA, the tiny Arduino-compatible sewable microcontroller capable of lighting up a constellation of LEDs based on simple sensors and actions. Propose your GEMMA hat project and you could win the parts to build your project, which could win you the grand prize!
The Challenge
Ten RoadTest challenge competitors will build electronics projects designed to be worn on the head using the Adafruit GEMMA sensor pack. Dress up like the ship in Close Encounters with flashing LEDs and simple tones, make a sparkling digital princess tiara for prom, stitch a VU meter baseball cap, or don a scrolling display matrix for your next DJ gig. We are looking for projects that stretch the tech as well as the craft of wearables.
We will be selecting the competitors after the enrolment period closes on August 4. Shortly thereafter, each competitor will be provided with a GEMMA Sensor Pack:
  • Adafruit Micro Lipo - USB LiIon/LiPoly charger - v1
  • Lithium Ion Polymer Battery - 3.7v 500mAh
  • Four Flora RGB NeoPixels V2
  • Stainless Thin Conductive Thread - 2 ply - 25 meter/85 ft
  • Photo cell (CdS photoresistor)
  • Small Alligator Clip Test Lead (set of 12)
  • GEMMA miniature wearable electronic platform
  • USB cable - A/MiniB - 3ft
  • Tactile On/Off Switch with Leads
  • Fast Vibration Sensor Switch (Easy to trigger)
  • Small Enclosed Piezo w/Wires
Oculus Rift Development Kit 2The competition will run from August 4th through October 31st. Competitors will be judged on their creativity, quality of documentation, and execution of craft. Throughout the build process, competitors will create blog posts in the element14 Wearable Technology group containing photos, videos, diagrams, code, and descriptive text to document their process. The winner will receive a grand prize of one Complete FLORA Collection parts pack from Adafruit. and an Oculus Rift Development Kit 2 courtesy of element14.

New to wearables? Check out episodes of Wearable Electronics with Becky Stern Live on YouTube to learn more about GEMMA and the Hats Off Challenge! We’ll get inspired by DIY projects that could spark your clever headgear idea, and take questions pertaining to wearables and the challenge. Submit your questions now and we’ll answer them on the show, or ask them live and we’ll answer them in the comments.
