Made of Imagination: Digital Pianola
The Digital Pianola riffs on player pianos of yore by letting users compose music from paper and light. To create their contraption, designers Benjamin Weetman, Zahra Shahabi Sirjani, and Hal Gillilan perforated more than 130 feet of print roll paper with a vinyl cutter, picking out the perforated dots.
As the paper passes through a strip of light-dependent resistors working in unison through Arduino and Logic, the removed dots cause light to shine onto light-dependent resistors (or LDRs), thus triggering MIDI samples.
