an ensemble of mechatronic scraper-class percussion, inspired by the Chinese yu. 2017.
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.
A modern re-visioning of the traditional Chinese yu, consisting of 27 serrates, 1 solenoid, 1 servo, and a handmade scraper made of 15 stalks of bamboo.
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.
