This project is part of the autonomous underwater vehicle I’m building in Paris. An AUV, or autonomous underwater vehicle, is basically a robot submarine: a compact system that has to balance power delivery, data integrity, sealing, vibration, and electromagnetic noise in a very small space. For this payload interface board, I designed a custom PCB … Read more about AUV Interface PCB for High-Speed Differential Signaling and Control

I redesigned the electrical system for Sn.AI.l to turn a collection of modules into one reliable robot power-and-control platform. The PCB tied together the Jetson Orin Nano, motor control, the head servo, charging and battery management, soft shutdown, and wheel-encoder odometry. At first I prototyped the system with breadboards and temporary wiring, but it quickly … Read more about Designing the Custom PCB That Powered Sn.AI.l

Bringing AI Education to Life with Sn.AI.l This summer I had the opportunity to intern at the Institute for Intelligent Systems and Robotics (ISIR) in Paris, France. During my internship I designed the full electrical architecture and core software systems for an AI educational robot. A big part of that work was turning the robot … Read more about SN.AI.l — Developing a Robotics Platform for AI Education at ISIR

I built this project to turn a compact ESP8266 board into a reliable Wi-Fi weather station that could measure temperature and humidity, publish the data online, and log it over time. It was a small embedded system, but it covered the same core ideas that matter in IoT work: sensor integration, wireless telemetry, cloud connectivity, … Read more about ESP8266 IoT Weather Station with Wi-Fi Telemetry and Cloud Logging

Student residence captive portal login screen before the router-side reauthentication flow takes over. In many student residences across France, internet access is handled through a captive portal called Wifirst. Instead of giving devices normal network access immediately, it interrupts traffic until you go through a login or validation flow in the browser. That might be … Read more about Automating Captive Portal Reauthentication for Student Residence Networks
