Owning the Telemetry: Why I Built a Custom ESP32 BMS from Scratch

Ditching the Arduino framework wasn't about elitism; it was a necessary shift from unpredictable polling to deterministic engineering. In this post, I explore why I abandoned black-box ICs to architect a custom ESP32 Battery Management System using FreeRTOS, raw I2C register manipulation, and why mastering silicon datasheets is the ultimate superpower for embedded engineers.

Beyond "It Works": Why I Migrated to NixOS for Embedded Engineering

Migrating to NixOS wasn't about trying a new distro; it was a shift from imperative maintenance to declarative engineering. In this post, I explore how I solved 'Dependency Hell' in embedded workflows using Nix Flakes, achieved bit-for-bit system reproducibility, and why I believe modern EEE students should treat their development environment as Infrastructure as Code (IaC).
