Want to create a beautiful, Wi-Fi controllable LED cat lamp? In this workshop, you’ll put together a “Purrsheen” cat shaped Wi-Fi lamp that allows you to control your adorable cat baby via Home Assistant with WLED. This workshop teaches about rapid prototyping and open-source, Internet-controlled LED art.

To anyone interested in off-grid communication at a low cost, Meshtastic allows even beginners to communicate with (or control) devices from miles away. Thanks to applications in emergency communication, sensor monitoring, and censor-proof encrypted chat, Meshtastic is exploding in popularity even as the cost for making nodes is going down. This talk will cover the basics of Meshtastic, setting up and customizing nodes, plus outlining the tips and tricks to building affordable custom Meshtastic nodes, learned from building custom Nibble Meshtastic nodes for the conference. Attacks against Meshtastic and issues observed in the wild will also be covered. Expect to learn about LoRa, Meshtastic node and antenna options, how to deploy nodes for specific applications, attacks against Meshtastic, and how to join larger mesh networks in your local area!

Beginners can now create off-grid, encrypted mesh networks for cheap, with applications in emergency communication, sensor monitoring, and more. These mesh networks have been popping up in cities all over the world, and this class will go over everything a beginner needs to run or build their own nodes. If you’ve ever wanted to legally create off-grid, encrypted mesh networks that can span over a hundred miles, you can get started with building Meshtastic nodes! This workshop will serve as a beginner user’s guide to Meshtastic, covering everything from hardware building to software configuration and modules. You will create custom Meshtastic nodes, set them up to transmit, and explore the built-in modules and how they work. Attendees will learn to solder their own Nibble Meshtastic nodes, select antenna options, configure software, and deploy their own weather-sensor nodes.

This workshop offers hands-on instruction using a unique, cat-shaped Wi-Fi hacking microcontroller, the Wi-Fi Nugget. Designed to engage participants in practical learning, essential skills for defending against four common, yet powerful Wi-Fi attacks will be covered. Participants will explore topics like detecting Wi-Fi leaks, the risks of QR codes leading to hidden networks, spotting phishing networks, and defending against advanced Wi-Fi karma attacks. The Wi-Fi Nugget is a powerful tool for understanding and fighting back against Wi-Fi hacking. This workshop is suitable for Wi-Fi hacking experts and those just getting started.

Meshtastic is a long range, encrypted, off-grid mesh protocol that features many powerful modules, configurations, and settings. For beginners just getting started, it can be confusing to dive into these features. In this workshop, you’ll explore the exciting modules that make Meshtastic more fun and useful. You’ll learn how to customize the encryption, add hardware like GPS and sensors, and change the default transmission settings to adapt to specific environments. Attendees will learn to customize their Meshtastic nodes for any situation using the built-in modules and settings. You’ll also learn about attacks against Meshtastic, and how to get involved in your local area!

In this workshop you’ll learn to write bad USB scripts to automate computer hacking using a cute, cat-themed hacking tool called the Nugget. You’ll learn to write scripts to get computers of any operating system to do your bidding in seconds, and how to automate nearly any desired action remotely through its Wi-Fi interface. If you’re looking for an introduction to simple scripting that’s a little more spicy, this class is for you!

Want to become a Wi-Fi investigator? You can uncover hidden cameras, network intruders, and more with the Wi-Fi Nugget! In this workshop you’ll use a cute, cat-shaped microcontroller board to catch hackers using common Wi-Fi hacking tools like a Wi-Fi Pineapple, hunt down suspicious Wi-Fi devices like hidden cameras, and detect jamming attacks. Attendees will explore how low-cost microcontrollers can be used to unmask and track down Wi-Fi hacking tools, or locate unwanted devices intruding on your local network.
