The Techno Guerrilla series is about building capability from open-source software and inexpensive parts: technology you can source or salvage, repurpose, and rebuild, then use to fight, resist, broadcast, or hack.

This is your workspace. Open Modules and start with 00 Hardening. They build on each other, so take them in order. The Terminal is a real shell with hands-on Linux drills: type learn for the list. Music plays net radio while you work, the BBS is a live lobby to ask questions and swap ideas, and Mail reaches the Light Fighter Manifesto crew directly. Hit Compose if you get stuck. The Onion Service icon has this site's Tor onion address.

This is a living workspace. Modules are revised and new ones ship as the series grows. Reload the page any time to get the latest version.

ONION SERVICE~/tor

The onion service is not a copy of this site. It carries sub-modules that are published nowhere else; each sits under a module from the public series and goes further than the public site can.

The address:

lfmnggwzl4f5ytjz4vc6mpbfvovurucg2gixspfeligae7c3yymb2jid.onion

Open it in Brave's private window with Tor, or the Tor Browser. Brave routes through Tor as a proxy; the Tor Browser gives stronger anonymity.

MODULES~/modules

// start with 00

00

Hardening

You will secure the phone and laptop you already own against the companies and agencies that can already read them. The module walks you through a threat model, a phone and laptop lockdown, account security, and the SSH keys that later modules depend on.

Start

01

Networking

You will build a private server on a Raspberry Pi that carries your chat, filters your DNS, and connects your devices through a VPN. Nothing on it is exposed to the public internet, and you administer all of it yourself.

Start

02

Electronics

You will learn how current, voltage, and resistance behave in a circuit and what each common component does. By the end you can read a schematic and verify a real circuit with a multimeter.

Start

03

Building Circuits

You will turn schematics into working hardware: each circuit is drawn in KiCad, proven on a breadboard, and then handed to a Raspberry Pi to control. The module ends with two complete builds, an isolated switch and a self-powered tamper node.

Start

04

Salvage

You will stock your bench with parts pulled from discarded electronics instead of a retailer's supply chain. The module teaches you where to find donor devices, how to open them safely, how to read their documentation, and how to test every component before it goes into a build.

Start

05

Power

You will run real equipment with no wall socket and no generator: measure the load with your own meter, salvage and test lead-acid and LiFePO4 batteries, build them into a fused bank, charge it by its chemistry's profile and from the sun, and prove the runtime on a dated record.

Start

06

RF Theory

You will learn what a radio link physically is: the wave, its power, the path it travels, the antenna, and the receiver. By the end you can predict a link over real terrain, then survey the spectrum to check the prediction.

Start

07

Assessing a Structure

You will read a structure from the outside in: its electrical service from open sources through to the panel, and its radio environment from the antennas to a spectrum sweep. By the end you can baseline what is normal at a site.
