The “Thereping” is a digital musical instrument that plays sounds based on a combination of the position of your hand and some pushbutton switches.
It uses a combination of a sonar sensor and a microcontroller to allow the user to play interesting melodies without requiring any musical skills.
When joined together with a “Thereclock” sync unit, multiple Therepings can all play together and create interesting music, again without requiring any musical expertise on the part of the players.
