Earlier this month @MakerFaire, the team over at Dentaku demonstrated how you can take conductive material – broccoli, for example – and use its product, Ototo, to turn them into musical instruments- like a keyboard. The Ototo has four sensor inputs, one for pitch, loudness and to control the texture of sound. At Maker Faire they demonstrated how produce could be used as the “keys.” Imagine playing Chopin’s Chopsticks (or maybe just Three Blind Mice, depending on your level of musical skill) to entertain the family at dinner, utilizing the broccoli as your keyboard!
The Ototo uses a technology known as “capacitive sensing.” The web site explains.“The Ototo is measuring the capacitance of the objects attached to it, once you touch the object it can sense the additional capacitance added from the human body which then triggers the note. It’s a simpler version of what’s happening on trackpads and smartphones. Which also means touching connected objects through other conductive materials will have the same effect. For example, playing a pot and pan drum kit with metal drumsticks would have the same effect as using your hands.”
