How To: Detect & Classify Wi-Fi Jamming Packets with the NodeMCU

The most common Wi-Fi jamming attacks leverage deauthentication and disassociation packets to attack networks. This allows a low-cost ESP8266-based device programmed in Arduino to detect and classify Wi-Fi denial-of-service attacks by lighting a different color LED for each type of packet. The pattern of these colors can also allow us to fingerprint the tool being used to attack the network.

NR30: The Mobile AR Leaders of 2018

This time last year, we got our first taste of what mobile app developers could do in augmented reality with Apple's ARKit. Most people had never heard of Animojis. Google's AR platform was still Tango. Snapchat introduced its World Lens AR experiences. Most mobile AR experiences existing in the wild were marker-based offerings from the likes of Blippar and Zappar or generic Pokémon GO knock-offs.

How To: Use MDK3 for Advanced Wi-Fi Jamming

You may have heard of a signal jammer before, which usually refers to a device that blasts out a strong enough radio signal to drown out the reception of nearby devices like cell phones. Purpose-built jammer hardware is outright illegal in many countries. Still, Wi-Fi is vulnerable to several different jamming attacks that can be done with Kali Linux and a wireless network adapter.

How To: Build Wonder Woman's Armor for Halloween

Wonder Woman has always been a Halloween and cosplay staple. It's a costume that's both dependable and stylish — just like the Amazon who wears it. This year's reprise with Gal Gadot offers a fresh take on the old standby, with more muted colors, a tougher demeanor, and a decided lack of stars or stripes. Tahnee Harrison from CineFix's DIY Costume Squad has come up with a compromise between the old and new costumes. It's got the cut, styling, and details of Gal Gadot's 2017 costume, but the b...

NR50: The People Leading Augmented & Mixed Reality's Head-Mounted Displays

A new technological movement without the technology itself is just an idea sitting and waiting. Once the technology is present in the equation, movement forward can begin. This is how many of us see the head-mounted displays (HMDs) and smartglasses that have recently entered the augmented and mixed reality market — or are coming out in the next few months. This is a movement that will sweep over the world, changing everything in its path, and these are some of the people behind it.

How To: 19 Tips for Making the Most of the Health App on Your iPhone

It's not easy staying fit and healthy these days with addicting phones, oversized portions, and long workdays, to name just a few things. To succeed, it takes work, commitment, and an understanding of your mind and body — and your iPhone can help you with some of that. While Apple pushed its Screen Time tool to help curb unhealthy smartphone habits, its "Health" app can help with everything else.

How To: Program a $6 NodeMCU to Detect Wi-Fi Jamming Attacks in the Arduino IDE

Hackers and makers are often grouped under the same label. While hackers draw on computer science skills to write programs and find bugs, makers use electrical engineering to create hardware prototypes from microprocessor boards like the Arduino. We'll exercise both sets of skills to program a $6 NodeMCU to display the status of a Wi-Fi link via an LED, allowing us to monitor for jamming attacks.

Coming Sept. 12: iPhone XS, XS Max & iPhone XR — Everything We Know So Far About Apple's 2018 Lineup

The iPhone X was released in November 2017, and the iPhone 8 and 8 Plus dropped right before it, but the hottest news right now revolves around the 2018 iPhone releases. The rumor mill regarding the iPhone X's successor started churning out speculations on names, cameras, display size, and more almost immediately after last year's devices, and there have been many new leaked details since.

How To: The Complete Guide on How to Build a Crystal Radio—Plus How They Work

There's a lot that goes into making a nice crystal radio set, so this is going to have to be broken down into two parts. The first part is the actual making of a functional radio, and the second part is making the whole arrangement look nice. In this part, I'm actually going to tell you more than just how to make a crystal radio, but I'm also going to explain how and why they work. Crystal radios are pretty Steampunk in and of themselves, since they were first developed in the late 19th centu...

How To: Apple's Massive Calculator Update Lets You Convert Currency, Area, Length, Time, and Other Measurement Units with Ease

Apple's Calculator app received a massive redesign, making it so much more than a simple calculator with built-in scientific functions. There's a new Math Notes feature that ties in with the Notes app, it can keep a history of your calculations, and you can even convert over 200 currency and measurement units.

How To: This Is What Happens to Your iPhone Every Time You Turn On Low Power Mode

When you enable Low Power Mode on your iPhone, it's not always clear what measures it's taking to reduce battery drain and conserve power. Changes to energy-hungry features you use daily may be immediately noticeable, but some things you frequently use may be disabled or reduced without any apparent indicators.

News: Inside the Future of Smartglasses: Vuzix CEO Paul Travers on What 2021 Holds for AR Wearables

We often discuss the augmented reality efforts coming from the biggest players in Silicon Valley like Google, Facebook, Apple, and others, but one name that keeps coming up when you really begin to dig into the AR space is Vuzix. Since the late '90s, the company has quietly but deliberately worked to build itself into a viable competitor in the enterprise space via its wearable display technology.

How To: Take Screenshots on Your iPhone 12, 12 Pro, 12 Pro Max, or 12 Mini in 6 Different Ways

If you just got an iPhone 12, 12 Pro, 12 Pro Max, or 12 mini, and you've never owned an iPhone before, some of the most basic tasks can be baffling. Shutting it down, force-restarting it, quitting apps, and even viewing the percentage of battery remaining sound simple but aren't very intuitive for new iPhone owners. Another big question mark is screenshots, and there are several ways to take them.

News: Apple Watch vs. Fitbit — What's the Best Bang for Your Buck?
