NUZZLE: An Arduino Light-Up PomPom Hat That Reacts to Your Loved One


Nuzzle is an electronics-embeded beanie set that lights up when the two hats are touched together. Designed by first year MFA Products of Design student Karen Vellensky, Nuzzle is prefect for couples, families, kids or close friends, providing them a way to display their affection and delight those around them.

“We all know happiness is contagious, and Nuzzle is a great way to share with others the thrill of being close to a loved one.”

 

Ideal around holiday-time, Vellensky tested the prototypes at the famous Rockefeller Center tree lighting, and the reaction was unanimous. “We all know happiness is contagious," she comments, "and Nuzzle is a great way to share with others the thrill of being close to a loved one.” 

Under the hood (pun intended!), the hat uses two circuits: The first, connected to the LED, is always closed and carries the current. The second circuit—the switch—is made of conductive yarn, knitted into the structure of both brims, and closes when the conductive yarn of the hats touch. The LED in the pompom is activated when an Arduino Uno board—connected to both circuits from the back of the hat—reads the switch as closed, and sends a current of electricity to the LED. Separating the switch from the LED circuit keeps electricity from traveling against the skin of the wearer, preventing any chance of a short circuit.
