PROT-015: KINETIC-SOLENOIDCLEARANCE: BLACK-BOXSTATUS: CONTAINED HAZARDYEAR: 2023

Discipline: Speculative Engineering · Lead Researcher: Dr. Evelyn O'Connor

OPERATIONAL ABSTRACT

A robotic acoustic percussion instrument featuring 32 individually actuated spring steel tines struck by high-speed push-pull solenoids.

TECHNICAL SUMMARY & TRANSDUCTION DYNAMICS

High-speed MOSFET driver stages deliver micro-second electrical impulses to low-inertia solenoids, achieving dynamic volume control across a 60 dB acoustic range. Calibrated for studio and field use under ZIAA experimental protocols. Harmonic distortion measured under 0.02% across primary operating range.
