This DIY Thermometer Scarf Measures the Temperature Outside
If it's feeling particularly frigid outside, you don’t need to pull up a weather app to check the temperature. Instead, just stitch together your own high-tech scarf that doubles as a wearable thermometer.
Instructables user caitlinsdad recently published step-by-step instructions on how to make a light-up thermometer scarf at home. To start, you’ll need an Adafruit Flora Arduino board, an Adafruit NeoPixel RGB LED strip, fabric, humidity and temperature sensor modules, and some basic sewing and soldering skills.
Once your accessory has been assembled, you can watch the LED light scale the length of your handcrafted thermometer as you switch settings from indoors to outdoors. You can also customize the scarf to your liking.
Update the light’s color scheme to match your mood or add GPS capabilities to map out your readings. If you’re looking to make your scarf practical as well as pretty, you can add haptic feedback alarms that will alert you when you’ve been out in the cold or heat for too long.
