A Pocket Airspace Display Built on an ESP32, Not Radar
Mateusz Juszczyk’s ESP32-Plane-Radar turns a round LCD and a small microcontroller into a desktop view of local airspace, with the important caveat that it does not actually sense with radar.
Introduction
Some projects win attention because they do exactly what their name suggests. Others are more interesting because the name overpromises and the build itself quietly explains the truth. ESP32-Plane-Radar sits in that second category: a compact desktop gadget with a circular display that visualizes nearby airspace, while leaving real radar hardware out of the equation.
The appeal is easy to understand. An ESP32 is small enough for a desk ornament and capable enough for connected displays, and a round LCD gives the project the look of a miniature instrument panel. What matters here is not military-grade sensing or hidden complexity. It is the tidy combination of embedded hardware, a visual interface, and an aviation-themed presentation.
Fast Facts
- ESP32-Plane-Radar is a desktop project built by Mateusz Juszczyk.
- The gadget uses a round LCD as its main visual element.
- Despite its name, it does not actually use radar.
- The build is presented as a way to keep tabs on local airspace.
- The project is a maker-style display, not a sensing instrument in the radar sense.
Body
The technical lesson is straightforward: appearance can suggest one kind of capability while the underlying hardware provides another. A round screen and a polished aircraft-themed interface can make a device feel like a live aviation monitor, but the confirmed detail that it is not radar keeps the project in the realm of display and visualization rather than direct detection.
That distinction matters in electronics projects because naming shapes expectations. When a build uses a microcontroller like the ESP32, the real engineering challenge is often integration rather than raw sensing power - fitting the firmware, the display, and the data presentation into a compact, reliable package. In other words, the project’s value is in how it packages information, not in pretending to capture it through hardware it does not have.
For readers who follow maker culture, this is also a reminder that hobby projects often blend practical engineering with theatrical presentation. A clean interface can make a small device feel much bigger than it is. That is part of the craft. It is also why careful labeling is useful: it helps distinguish a visual dashboard from a true sensor system.
The broader lesson is modest but useful. Small embedded builds are often judged by the story they tell as much as by the chips inside them, and the best ones stay honest about that boundary.
Conclusion
ESP32-Plane-Radar is a neat reminder that good hardware design is not always about adding more sensing. Sometimes it is about turning a simple microcontroller and a well-chosen screen into a convincing, readable window onto a subject - as long as the label stays true to the build.
