I decided to make this project after we put our resources to space! Without a engine there is no way to get there so we had to make our own. Introducing the Proton! It is a Hybrid Rocket Engine running on Paraffin wax as a fuel and Nitrous as a oxidizer. We designed it so anyone with the dedication and resources to put it together can use it.

Technically it is not a Arduino but the computer that runs the engine is a PCB with the teensy 3.2 board on it so basically, it can use the Arduino environment.

EXPANDED TECHNICAL DETAILS

Aerospace Propulsion Control Hub

This advanced scientific project uses an Arduino to manage the ignition, valving, and high-speed data logging for a small-scale hybrid rocket motor.

• Secure Ignition Sequence: Implements a "Double-Key" software latch. The Arduino will not trigger the glow-plug or spark-initiator unless both a physical key and a software "Arm" command are present.
• Cryogenic Valve Actuation: Manages the high-torque servos that open the oxidizer (e.g., Nitrous Oxide) valves. The firmware includes a "Timed Burn" logic that closes the valves at precisely the T+5 second mark.

Reliability

• High-G Data Logging: Captures data from a 200kg load cell (HX711) and a high-speed pressure sensor at 80Hz, storing the thrust-curve to an internal SD card for post-flight analysis.
