I have successfully completed my first altimeter device and plan to deploy it as a small payload on my Corporal rocket build scheduled for September.

Key Accomplishments

  • Functional altimeter with proper operation
  • Cost-effective design at approximately $40, competitive with commercial alternatives
  • Included schematics and operational code available for reference

Testing Plan

The flight will evaluate three critical aspects:

  1. Connection resilience under flight conditions
  2. SD card write performance
  3. The device's capacity to capture accurate pressure and altitude readings during the rocket's trajectory

Future Development

I am currently designing and prototyping a protective case to minimize vibration and mechanical stress on the electronics during flight. Once the enclosure is finalized, the GitHub repository will receive a comprehensive update including complete bill of materials and assembly documentation.

Long-term plans involve developing a custom PCB with integrated connections and potentially a full flight computer system.
