Build a Desktop Flight Tracker with an ESP32 and Zero Soldering

For many makers and hardware hackers, collecting data is half the fun of their projects. They don't just want to know what's happening in the wider world — they want a better understanding of what's happening in their own backyards. That curiosity has inspired countless DIY weather stations, air quality monitors, and custom sensor projects that measure everything from temperature and humidity to airborne particles and noise levels.

For Anthony Sturdy, it’s airplanes that are of interest. He wants to know where they are, where they came from, and where they are going. To make that possible, he created a device that is simply called Micro Radar. It is a tiny, open source flight tracker built for desktop use. You can build your own with a single development board, and you won’t even need to solder any wires.
