Building a Telemetry Ingestion API for eVTOL Prototyping with FastAPI and Pydantic
Short summary
A developer built 'aero-telemetry', an open-source FastAPI/Pydantic telemetry ingestion API for eVTOL prototyping that validates sensor data (battery, GPS, IMU, motor RPM) against aerospace-realistic ranges. It uses SQLite by default with SQLAlchemy 2.0 async, a repository pattern, and 26 pytest tests. v0.1.0 is Apache-2.0 licensed with PostgreSQL, WebSocket streaming, and Grafana integration on the roadmap.
