Microtonal Basalt Lithophone with Piezoelectric Actuator Mallets (Revision 2.1)
Discipline: Applied Anomalies · Lead Researcher: Dr. Kenji Takahashi
OPERATIONAL ABSTRACT
A 24-note microtonally tuned mineral lithophone carved from volcanic basalt slabs, struck by velocity-sensitive electromagnetic solenoid mallets with contact piezo pickup arrays. Enhanced revision 2 with improved low-noise shielding and updated real-time firmware.
TECHNICAL SUMMARY & TRANSDUCTION DYNAMICS
Natural grain boundaries in aged volcanic stone produce prolonged sustain with non-harmonic modal decay. Solenoid mallets driven by 32-bit microcontrollers allow automated algorithmic polyphony with micro-second strike precision. Calibrated for studio and field use under ZIAA experimental protocols. Harmonic distortion measured under 0.02% across primary operating range.
