Topics I Always Enjoy Discussing

  • Embedded Systems & Electronics: ESP32 / ESP32-S3, ESP-IDF, FreeRTOS, SPI/I2C/PWM/PCNT peripherals, schematic capture, and breadboard-to-perfboard builds.
  • Systems Programming: ISO C99, C++, Rust, Python hardware tooling, and low-level memory/assembly analysis.
  • RF Telemetry & Robotics: 2.4 GHz nRF24L01+ wireless control links, Hall-effect gimbals, and 4WD autonomous vehicle control loops.
  • Reverse Engineering & Linux Internals: Studying binary behavior with Ghidra, x64dbg, Cheat Engine, and Wine/Proton runtime compatibility on Arch Linux.
