Ben Heck’s Parallax Sensor Seeing-Eye Hat (4x59)

Air date: Dec 12, 2014

Ben finally tries out an idea he’s had in mind for years - a seeing-eye hat! Ben uses a Parallax Propeller, ultrasonic sensors, and rumble motors to create a hat that helps the wearer to sense their surroundings. His challenge is to create a prototype that lets Ben wander around his shop blindfolded and still have an idea of where he is. Can he do it?
