How to use your cat to hack your neighbors’ wi-fi

1407693589-0.jpg

Pictured above is Coco, a cat and a computer hacker. She probably doesn’t know about that last part. Gene Bransfield, a computer security expert, outfitted her with a collar that mapped Wi-Fi networks as she roamed her neighborhood. Andy Greenberg of Wired describes how it works:

And Bransfield had built into that collar a Spark Core chip loaded with his custom-coded firmware, a Wi-Fi card, a tiny GPS module and a battery—everything necessary to map all the networks in the neighborhood that would be vulnerable to any intruder or Wi-Fi mooch with, at most, some simple crypto-cracking tools.

This is similar to the practice of “wardriving”–driving around in a car, searching for unprotected Wi-Fi networks. Coco does the same thing on four feet with the help of Bransfield’s “WarKitteh” collar, which cost him just $100 to build. He will give a presentation about it at DefCon, a convention about computer hacking and security.

MaxLinear Integrates Analog & Digital Design in One Chip with Cadence 3D Solvers

Sponsored by Cadence Design Systems

MaxLinear has the unique capability of integrating analog and digital design on the same chip. Because of this, the team developed some interesting technology in the communication space. In the optical infrastructure domain, they created the first fully integrated 5nm CMOS PAM4 DSP. All their products solve critical communication and high-frequency analysis challenges.

Learn more about how MaxLinear is using Cadence’s Clarity 3D Solver and EMX Planar 3D Solver in their design process.

Designing Robust 5G Power Amplifiers for the Real World

Sponsored by Keysight

Simulating 5G power amplifier (PA) designs at the component and system levels with authentic modulation and high-fidelity behavioral models increases predictability, lowers risk, and shrinks schedules. Simulation software enables multi-technology layout and multi-domain analysis, evaluating the impacts of 5G PA design choices while delivering accurate results in a single virtual workspace. This application note delves into how authentic modulation enhances predictability and performance in 5G millimeter-wave systems.

How Capacitive Absolute Encoders Enable Precise Motion Control
Encoders are a great way to provide motion feedback and capture vital rotary motion information. In this episode of Chalk Talk, Amelia Dalton and Jeff Smoot from CUI Devices investigate the benefits and drawbacks of different encoder solutions. They also explore the unique system advantages of absolute encoders and how you can get started using a CUI Devices absolute encoder in your next design.
