Extensions over extension…after I thought I’ve finished the project with a radarmodule I added a lidar and a thermal camera. Just to make sure to detect the alien correctly.
Just for fun, I built a portable radar device. The radar itself is housed in a small enclosure and transmits the signal via Wi-Fi to the display unit.
In this example, we used the radar during a training exercise to test, under zero-visibility conditions, how long it takes the assault team to reach the targets and where they are located in the space.
Alongside the original Arduino Giga R1 + Display Shield setup, this project now has a second, standalone output path built around the Clockwork Pi uConsole (or any Linux machine with WiFi + audio).
Architecture
The XIAO ESP32-S3 (with the RD-03D attached) now runs as its own WiFi access point instead of connecting to a host device. It reads the radar, clusters targets within 1m of each other into a single point, and broadcasts the merged data over UDP — any device connected to its network automatically receives the stream, no fixed IP configuration needed.
A Python script (Pygame + NumPy) running on the uConsole connects to that access point and handles the rest: fullscreen radar visualization (auto-detects the actual display resolution) and audio, entirely replacing the Arduino display + piezo buzzer from the original build.

RADAR UPDATE 📡
Three new features on the tracker build:
https://github.com/Stevee87/Arduino-ESP32-Radarproject
🔋 BATTERY INDICATOR
Live voltage readout, right on the display. No more guessing when the LiPo's about to tap out mid-build session.
🔇 MUTE BUTTON
Touchscreen toggle on the Giga display — tap to silence the tracker sound instantly. Because sometimes you just want the visual without the beeping.
🔊 SOUND MODULE
Proximity-reactive audio — pings speed up and climb in pitch as a target gets closer. Distance-mapped, non-blocking, runs straight off a passive piezo buzzer.
Still just an RD-03D 24GHz mmWave sensor + Arduino Giga R1 + a lot of trial and error.

Just build this box with a arduino giga r1 and a lot of sensors to detect co, co2, ch4 and o2. Internal 10000mah battery, step up and down converter and 2 fans for the airflow through the body
What started with just an idea turned out pretty complex after a while…detects co, co2, o2 and ch4 pretty precise
