I built a simple radar + dashboard in about 40 minutes.
I had a servo motor, ultrasonic sensor, and an ESP32 sitting around, so I got curious about what I could make with them.
The setup is pretty simple: the servo sweeps the sensor, the ESP32 reads the distance, and that data is sent to a small web dashboard that visualizes it in real time.
This little experiment got me into microcontrollers a few months ago. Since then, I've built an outdoor smart pot and an autonomous robot.
I'll be sharing more of that IoT journey in the next few posts.

The challenge? Making desktop and mobile cryptographically compatible while minimizing plaintext exposure.
From encryption to cloud sync to my shot at anomaly detection, this turned into a full security-focused product.
