Instructables member caitlinsdad has a wide range of interests and crafts, including jalapeño poppers with tails, a shelf that looks like the Enterprise, and a theremin bra that plays Star Wars music.
His latest project is equally fashionable and practical. This scarf measures and displays the temperature. It has a temperature sensor and a strip of LEDs that glow incrementally with an Arduino controller as the sensor indicates greater heat.
