Excuse me while I make a deep 90s reference, but Pulitzer Prize winning journalist Mary Schmich has nothing on this hat! As the illustrious Becky Stern demonstrates in this fantastic tutorial video from adafruit, this fetching sun hat is outfitted with a wearable microcontroller that’s been programmed to alert you when it’s time for you to reapply sunscreen!
This sewable circuit uses a FLORA sewable microcontroller and its compatible UV index sensor to sense the sun and play a tune on a piezo buzzer when its time to refresh your SPF.
