Projects
Everything I build is to better see and characterize the world around me.
In progress now
Building a hall-effect magnetometer from first principles. Biot-Savart derivation, vector math, beautiful 3D field mapping.
- · Biot-Savart Law
- · Vector calculus
- · Calibration methodology
- · Magnetic field diagnostics
- · Arduino Uno R3
- · Matplotlib
- · Python
Magnetic diagnostics in tokamaks use the same instrumentation principles.
Mapping the resonant modes of an Ibanez AS73G semi-hollow electric guitar using frequency sweep, and impulse response. The Helmholtz resonance of the body cavity connects directly to plasma oscillation modes.
- · Wave equation on bounded domain
- · Helmholtz resonance
- · Standing wave modes
- · Mechanical impedance
- · iPhone
- · Python FFT
- · Audacity
The eigenvalue problem for acoustic modes is identical in structure to quantum mechanical bound states and plasma wave modes. Different boundary conditions, same mathematics.
Real-time OBDII data acquisition using an ESP32 microcontroller. Sensor fusion via Kalman filtering to estimate road grade, a quantity the car doesn't directly measure, using live accelerometer and vehicle dynamics data.
- · Kalman filtering
- · Sensor fusion
- · Vehicle dynamics
- · Optimal estimation theory
- · ESP32
- · OBDII
- · Python
Optimal estimation under Gaussian noise is the same mathematical framework used in plasma diagnostic systems and spacecraft attitude determination. The car is the accessible laboratory.
Coming next
Two coils separated by their radius produce a uniquely uniform central field. Derive the uniformity from Biot-Savart, verify it experimentally, and characterize a Hall sensor against it.
Build a Langmuir probe diagnostic for a plasma globe. The IV curve encodes electron temperature and density via the Maxwell-Boltzmann distribution. A direct fusion diagnostic technique at bench scale.
