Grunting Tennis Ball
Built by Pablo Rochat and Dalton M17
A sensor-filled tennis ball that triggers grunts from a Bluetooth speaker whenever it is hit.
Maker story
Pablo Rochat supplied the idea, while Dalton M17 built and programmed the electronics. Sensors hidden inside the ball detect play and connect to a courtside Bluetooth speaker, turning every rally into an overdramatic match.
