I built LUNATIK, a flight computer for our model rocket (Pico 2, CircuitPython) that fuses a barometer and accelerometer with a Kalman filter to detect apogee, logs to SD and streams LoRa telemetry. The hard part: we had one motor, so it had to work first try. I’m proud it did, calling apogee 0.45 s after the top while the motor’s charge fired 2.5 s later. To test without a rocket: python scripts/dashboard.py –simulate. Only coding hours were logged, not the hardware build.
