$96 3D-printed rocket that recalculates its mid-air trajectory using a $5 sensor

A proof-of-concept low-cost guided rocket system built with 3D-printed components and consumer electronics for approximately $96. The rocket uses an ESP32 flight computer and MPU6050 IMU for mid-air trajectory control via folding fins and canard stabilization, while the launcher integrates GPS, compass, and barometric sensors for orientation and telemetry. The system was designed in Fusion 360, simulated in OpenRocket, and validated through iterative mechanical, electronics, and launch testing.
