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.

Hardening
You will lock down the phone and laptop you already own against the companies and agencies that already have access to them. You will write a threat model, harden both operating systems, secure your accounts, and generate the SSH keys the rest of the course depends 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 measure current, voltage, and resistance with a multimeter, read a schematic, and identify what each common component does in a circuit.

        
Start

      

      

        
03

        
Building Circuits
You will turn schematics into working hardware: draw each circuit in KiCad, prove it on a breadboard, and wire it to a Raspberry Pi. You finish with two complete builds, an isolated switch and a self-powered tamper node.

        
Start

      

      

        
04

        
Salvage
You will pull usable parts from electronics other people threw away: motors, switches, batteries, circuit boards. You will open each device, identify the components inside, and test every part before you use it in a build.

        
Start

      

      

        
05

        
Power
You will read a building's electrical system to find a circuit you can draw power from. You will salvage and test batteries, wire them into a protected bank, charge the bank from the wall or from solar, and power your equipment from it to measure the runtime.
