# Building a Desk Plane Radar with ESP32
In a world where the Internet of Things (IoT) and DIY technologies are gaining momentum, transforming an ESP32 into a functional plane radar is both fascinating and achievable. This guide shows you how a bit of hardware and some lines of code can enable you to track real-time air traffic from your desk.
What is the ESP32?
The ESP32 is a popular microcontroller among tech enthusiasts. It's a low-cost board equipped with Wi-Fi and Bluetooth, ideal for IoT projects. With its processing capabilities and various I/O ports, the ESP32 is a perfect choice for innovative projects like our plane radar.
The Plane Radar Project
This project turns an ESP32-C3 and a 1.28-inch round display into a real-time plane radar. It uses ADS-B (Automatic Dependent Surveillance–Broadcast) traffic, an air surveillance technology that broadcasts the position and other data of aircraft.
Required Hardware
- ESP32-C3
- 1.28-inch round display
- Connecting wires
- USB power source
Software
The open-source firmware for this project is available on [GitHub](https://github.com/ironicbadger/ESP32-Plane-Radar). It retrieves ADS-B data from nearby aircraft, displays it on the screen, and allows advanced features like interface customization and OTA (Over-the-Air) updates.
Build Steps
- Soldering and Assembly
Start by soldering the connecting wires between the ESP32 and the display. Use silicone wires for easy handling and ensure the connections are secure.
- Flashing the Firmware
Use the ESPHome web flashing tool to load the firmware onto the ESP32. In under 30 seconds, your microcontroller is ready to operate.
- Software Configuration
Modify initial settings via the web interface to adjust coordinates, time format, and other display options.
Improvements and Customizations
Recent Additions
The latest project updates include displaying flight contexts, integrating local weather conditions, and customizing the user interface.
3D Model Customization
Although the original model is impressive, it may require adjustments to fit certain batches of boards. Print your own casing for a perfect fit.
Practical Use
Imagine having this plane radar on your desk, enabling you to track planes in real-time, whether for fun or more professional applications like air traffic monitoring.
Conclusion
This project shows how the ESP32, coupled with a bit of additional hardware, can create a useful and impressive application. Whether you're a tech enthusiast or a professional looking to monitor air traffic, this plane radar is an excellent addition to your desk.
