Fixing things that aren't broken, building things that probably shouldn't exist.

Welcome to Bare Metal Nerd.

I’m Fróes — an information security analyst by day, and a chaotic hardware/software tinkerer by heart. Have been breaking things for 15 years when taking it apart to see how it ticks (and spend days trying fixing it when it wouldn't work later).

  • •
    Microcontrollers & SBCs: ESP32, Raspberry Pi, Milk-V Duo, and breathing new life into old discarded hardware.
  • •
    Linux & Custom Kernels: Chroot on toasters and water bottles, wrestling with dotfiles, and optimization rabbit holes.
  • •
    Cybersecurity: Defense engineering, SOC log analysis, penetration testing, and analyzing network traffic.
  • •
    Electronics & Bits: Soldering custom gadgets, digital dashboards, analog circuits, and custom peripherals.

This blog is essentially an unfiltered dump of my adventures, documentation for projects that went off the rails, and notes on how to keep ancient or unconventional tech running purely out of spite.
