The best Hardware Hacking newsletters

A hands-on tinkering blog documenting a multi-part project to run OpenWrt on an AT&T BGW320-500 gateway, covering XGS-PON fibre, Wi-Fi bring-up and Ethernet/Runner driver loading. Readers get detailed, reproducible low-level engineering notes on reverse-engineering and porting firmware to specific hardware.

Shadow Codex is a technical newsletter from a long-time Shadow cloud gaming user who reimplements the client (Caligo) and ports it to Linux, macOS, Windows, Android TV and single-board computers. It also documents hands-on work such as running a modern Linux kernel and Debian on the discontinued Shadow Ghost hardware, with benchmarks and debugging detail.

Nikita Tokarchuk writes detailed, hands-on technical posts about niche engineering problems: packaging the official Claude desktop app as a Flatpak on Linux, booting Alpine Linux via direct kernel boot on an old macOS Monterey machine, and limiting charge current for a small LiPo battery in an old phone. Readers get concrete commands, file layouts, manifests and circuit reasoning they can reproduce.

A personal technical blog with step-by-step hardware and software fixes, covering Steam Frame headset tweaks and an Audi TPMS retrofit. Readers get exact commands, component locations and the reasoning behind each fix.

A hardware and IoT security engineer explains EU cyber regulations (the Radio Equipment Directive and the Cyber Resilience Act) and what manufacturers must do, especially around vulnerability reporting deadlines. The series mixes practical product-security perspective from someone working on both the hacker and manufacturer side.

A reverse engineering and security blog from Red Crow Lab mixing hands-on hardware and firmware hacking write-ups with opinionated commentary on the cyber security industry. Readers get practical walkthroughs with tools and commands alongside experienced-practitioner perspectives on security trends and tools like Signal.

Duncan Geere's newsletter collects his monthly notes and project write-ups as a data visualisation and sound artist, covering recent commissions like a data-driven music piece, a Dieselgate infographic for ClientEarth, and hardware hacking. Readers get a personal, practical look at how data is turned into art, design and sound work.

Zero Day is a cyber security blog with first-person, step-by-step write-ups of penetration testing rooms and hands-on hardware experiments, such as enumerating vhosts with ffuf, WordPress scanning, and USB HID attacks with the O.MG Cable. Readers get practical methodology and commands they can reproduce in labs.

A personal blog by Arnaud Fevrier mixing security research (a Red Hat ACM cross-cluster escalation write-up), hardware hacking (ESP32 USB passthrough for keyboard and mouse macros) and server tinkering (bypassing YouTube bot checks with Cloudflare WARP). Readers get detailed, first-person accounts of technical discoveries and the reasoning behind them.

A personal blog mixing Android development notes, such as solving a Jetpack Compose navigation error, with hands-on hardware hacking of a Zigbee Ethernet gateway. Readers get concise, practical write-ups of debugging steps and technical findings.

A personal blog by Santiago Moya documenting hardware and security projects, including a long-range LF badge reader, a drone jammer, a CAN bus tool, and a credential database built from leaked data. Each post mixes build notes with reflections on the ethics and legal risks of offensive security work.

TechAnarchy is a personal blog by a self-described grumpy Windows and PowerShell sysadmin who shares scripts, security research and career notes. Readers get practical PowerShell tips, reflections on Azure and Azure Stack Hub work, and hands-on analysis of hardware security tools such as the O.MG cable.
