01 / The problem
What had to change
A pilot needs current airport weather in a compact device without opening a full weather application.
02 / The constraints
What the system had to respect
- The software runs on a microcontroller.
- METAR data must fit a small display and limited interface.
- The device needs a direct, dependable readout.
03 / The build
What I made
- A Pi Pico W reader for METARs, TAFs, and other NOAA aviation-weather text products.
- Button navigation, line wrapping, and scrolling for a small Pimoroni display.
- A separate version for the M5Stack Cardputer.
04 / The result
The useful change
The project puts essential aviation weather on a small, purpose-built display.
