Is that a life flight that just flew low and fast over my head? Are the fire planes near by? Is that a police chopper circling or the news? Freeway flying speed traps...

Turn nearby air traffic into a tiny desktop radar. ESP32 Plane Radar is a compact Wi-Fi aircraft display built around an ESP32-C3 and a 1.28-inch round GC9A01 screen. Once configured, it shows nearby ADS-B aircraft on a classic sonar-style radar grid, including aircraft position, bearing, callsign/type/altitude tags, heading markers, and speed vectors.

This is a fun, glanceable gadget for aviation fans, makers, desk setups, ham/radio hobbyists, and anyone who has ever looked up at the sky and wondered what just flew over.

The device connects to your Wi-Fi, uses your configured latitude and longitude as the radar center, and pulls live aircraft data from the public adsb.fi open data API. Updates occur about every 5 seconds, giving the display a near-real-time “what’s around me?” feel.

Features

• Live nearby aircraft display using ADS-B data from adsb.fi
• Round radar-style interface with rings, crosshairs, compass labels, and center point
• Aircraft markers with heading triangles, speed vectors, and aircraft info tags
• Range presets: 5, 10, 15, and 25 km, selectable with the BOOT button
• Metric or miles display selectable during setup
• Wi-Fi setup portal via the PlaneRadar-Setup access point
• Persistent settings for Wi-Fi, location, units, and range
• ESP32-C3 based with 1.28-inch 240×240 GC9A01 round display
• Open-source firmware for makers who want to inspect, modify, or flash their own build

Setup

On first boot, connect to the PlaneRadar-Setup Wi-Fi network and open the setup page. Enter your home Wi-Fi, latitude/longitude, and preferred distance units. After saving, the device reconnects automatically and begins showing nearby aircraft.

A short press of the BOOT button cycles the radar range. Holding BOOT for 3 seconds clears Wi-Fi, location, and unit settings and reboots into setup mode.

Notes

ESP32 Plane Radar requires Wi-Fi and access to the adsb.fi API to display live aircraft. Aircraft visibility depends on available ADS-B coverage in your area and public data availability. This is a hobbyist situational-awareness display, not certified aviation equipment.

New model under development with onboard gps. Look for it this fall
