WiFi Shuriken

CoD_Segfault walked us through their WiFi Shuriken project — a custom wardriving hardware build — along with a deep dive into the history of wardriving. They covered everything from the early days of wardriving to modern microcontroller-based approaches and what it takes to go from a prototype to shipping hardware.

Slides from the talk are available on their GitHub.

A big thank you to Micah for presenting, and to everyone who came out to our first meeting of 2026!

Below is the run down on each for anyone who missed it.

Agentic Hacking in VS Code

amne51ac reprised their talk about agentic hacking in VS Code that they gave at SecretCon this year and walked us all through setting up RooCode to do some realtime hacking with AI as our copilot.

A couple things to remember when following along with the blog post on the HackerSidekick website:

  • Set the temperature to exactly 1.0 by going into RooCode’s advanced settings and setting a Custom Temperature
  • Remember to set the temperature for all modes, not just Architect
  • Failure to set the temperature to exactly 1.0 will cause a 4XX error

Soldering

bran gave us a deep dive on soldering and how it works, why it works, and how to do it right. Their slides are available in ODP format here.

They also shared some cool videos on how soldering works and how modern fabrication facilities function:
