Four electrical engineering students developed a new take on an old decoration: the wind chime! This electric wind chime doesn’t make sound by itself. When the center pendulum hits the chimes, it transfers the hit data to a microcontroller, which activates a small speaker on the chime. For louder notes, the microcontroller transfers the data wirelessly to a large xylophone-style chime, which has robot arms with mallets for each note. The tones can also be changed with just the touch of a button.
