serrae: an ensemble of serra(s)
serrae is a modular ensemble of serra, a mechatronic scraper-class percussion. The ensemble can have up to 16 units of serra connected simultaneously. Powered by a microcontroller, serrae provides the instrumentalist the affordances to independently scrap (at different velocity) and strike the 27 serrates of each individual serra unit, allowing dynamic and control multiplicity of the ensemble.

mechanisms
Mechanizing the sound-producing mechanisms of the Chinese Yu: a linear actuator (solenoid) to strike the surface of a serrate, and a radial actuator (servo) to scrap its 27 serrates.
