Things I've Built

MEMS-Based Gyrocompass

Gyroscopes mounted on a rotating platform and measurement fusion with a Kalman filter. No magnetic field needed — it finds north just by measuring the Earth’s spin! https://www.youtube.com/watch?v=U-fFy3L0FEQ

3D Sound Direction Detection System

A device that estimates the direction and elevation of a sound source using four microphones. It processes audio signals via FFT-based cross-correlation to determine time differences of arrival https://www.youtube.com/watch?v=_IeDw05at84
