Hey Everyone! I have been working on this project for 9 months now and I am finally ready to open source the flight computer!!! If you would like to build one and you need help contact me on my website: https://deltaspacesystems.wixsite.com/rockets

The kit to build the computer is on my website along with instructions.

Avionics Engineering: Rocket Flight Computer

The Advanced Rocket Flight Computer is an incredible project for aerospace hobbyists. When launching model rockets, you want to know exactly how high it went and how fast it accelerated. This tiny Arduino payload records all that data for later analysis.

Multi-Sensor Integration

A flight computer relies on the I2C Bus to pull data from multiple sensors simultaneously:

  1. BMP280 Barometer: Measures atmospheric pressure. As the rocket climbs, pressure drops. The Arduino uses the barometric formula to calculate the exact altitude above ground level.
  2. MPU6050 Accelerometer/Gyro: Records the G-forces of the launch and any wobble (spin) during the ascent.
  3. Micro SD Card Module: Because the rocket is out of Wi-Fi range, the Arduino writes hundreds of data points per second to a text file on an SD card for post-flight graphing.

Crucial Feature: Apogee Deployment

The most advanced feature is event detection. When the BMP280 sees the altitude stop increasing and start decreasing, it knows the rocket has reached the highest point (Apogee). The Arduino immediately sends a pulse to a relay or a nichrome wire match, igniting a small charge that blows off the nosecone and correctly deploys the recovery parachute!

Hardware Constraints

  • Arduino Pro Mini or Nano: Must be ultra-lightweight and run on 3.3V to match the sensors.
  • BMP280 and MPU6050 breakout boards.
  • Micro SD Card module.
  • High-Discharge LiPo Battery.

This project teaches you how to write highly optimized, non-blocking code because writing to an SD card while reading a barometer requires precise CPU management.
