[Rec]ing Ball is a experimental concept to find out if you would be able to present a surfice via audio. We set out to find out how a surface could sound like. By recording any surface with the hand held optical device that surface presents as audio via the connected speaker.
The [Rec]ing ball is made with Arduino and have a photo sensor which detects lights. The light is then transformed into notes. The faster you swipe the recorder over a surface the higher the tempo of the melody produced. A darker surface will produce a darker tone and a lighter surface will produce a lighter tone. You can even pause the recording and pick it up again at any time. These function together makes it possible to create, and play, any melody with the hand held recorder. And that with only two buttons.
