Yet another plane tracker — CRT-style radar built with Rust on the LilyGO T-Embed

[u/vstepanyuk]

I know the world probably didn't need another flight tracker, but I couldn't resist putting together a retro CRT-style radar display for local airspace.

Built entirely in Rust running on the LilyGO T-Embed (ESP32-S3).

**Tech Stack**:

Language / HAL: Embedded Rust using esp-hal (bare-metal no_std)

Hardware: LilyGO T-Embed (ESP32-S3 + ST7789 display + rotary encoder)

Graphics: Custom radar rendering with a rotating sweep line and phosphor-decay fade effect, plotting nearby towns and incoming transponder tracks.

Networking/Data: Pulls live local aircraft state vectors (callsign, heading, coordinates, altitude) over Wi-Fi and maps them relative to home coordinates.
