While hackers know and love the Raspberry Pi, many don't know of its cheaper cousin, the microcontroller. Unlike a Pi, which can be used more or less like a regular computer, microcontrollers like the Wi-Fi connected ESP8266 require some necessary programming skill to master. In this guide, we'll build an Arduino program from scratch and explain the code structure in a way anyone can understand.
Planning a vacation overseas can sometimes feel overwhelming with the number of things you need to remember before heading out. Since smartphones keep us connected at all times, it's essential that you have everything you need here as well. Unexpected events can arise while on your trip, and you should be prepared for anything like a survival expert.
In the last couple of days there's been a lot of speculation about the powers of Microsoft's HoloLens 2, but few have had a chance to get their hands on one to see if the company's claims live up to what HoloLens inventor Alex Kipman showed off on stage.
After poor sales of the Pixel 3 and Pixel 3 XL, Google needs to reinvigorate its Pixel lineup, devices it's been pushing heavily over the last couple years. On May 7, Google had the eyes and ears of the technology industry at its Google I/O keynote, making it the perfect time to announce new devices that would attract a different crowd of users. Meet the Pixel 3a and 3a XL.
In the battle for best stock Android flagships, there are really only two choices: Google Pixel phones and OnePlus phones. Although the latter isn't true stock Android, it is impressively close and usually paired with more impressive hardware than the Pixel lineup. The latest is the OnePlus 6T, which will be a bit controversial for fans this year.
Smartphones and other Wi-Fi enabled devices send radio signals called probe frames to locate nearby wireless networks, which makes them easy to track by listening for their unique MAC address. To show how this kind of tracking works, we can program a NodeMCU in Arduino to sniff the air for packets from any device we want to track, turning on an LED when it's detected nearby.
On the surface, AppleCare+ seems like an expensive and gimmicky option to tack onto your already pricey iPhone 11, 11 Pro, or 11 Pro Max. Upon further inspection, however, you'll see that its seemingly expensive price tag is chump change compared to the fees you'll have to pay if you end up having to repair your premium device outside its one-year warranty.
Apple's successor to the iPhone X is a beautifully made smartphone with much of the same characteristics, including a 5.8-inch OLED screen, two storage choices, and Face ID. But many features set the iPhone XS apart from its predecessor, as well as the other 2018 lineup of iPhones, making it a worthy choice to upgrade to if you're in the market for a new mobile device.
Three new iPhones means you have to make a choice: Do you go with the smaller iPhone XS, the larger iPhone XS Max, or the cheaper iPhone XR? There's lots to like about each model, but if you want to make an informed decision, it's time to learn what each has to offer. Here's what the iPhone XS Max brings to the table.
Hello, budding augmented reality developers! My name is Ambuj, and I'll be introducing all of you Next Reality readers to the world ARKit, as I'm developing an ARKit 101 series on using ARKit to create augmented reality apps for iPad and iPhone. My background is in software engineering, and I've been working on iOS apps for the past three years.

One of the best things about Android is the ability to customize your phone to your liking. From changing the layout of icons to finding the perfect wallpaper to reflect your current mood, there's a wide range of tools to make your phone yours.
As unappealing as it sounds, transplants with fecal material from healthy donors help treat tough Clostridium difficile gastrointestinal infections. Researchers credit the treatment's success to its ability to restore a healthy bacterial balance to the bowels, and new research has shown that the transplanted bacteria doesn't just do its job and leave. The good fecal bacteria and its benefits can persist for years.
On April 7, 2017, residents in Dallas, Texas, woke to the sound of emergency sirens blaring all over the city. No one could shut them off, and after repeated efforts to contain the situation, the city had to shut down the entire system. While the media reported a sophisticated computer hack was responsible, the truth was much less high-tech.
Black Mirror, Netflix's technology-horror anthology, never fails to provide thought-provoking entertainment centered around emerging and futuristic technologies, and the third season's second episode, "Playtest," delves deep into the worlds of mixed, augmented, and virtual reality. While designed to leave you haunted by the end, offering a more "evil" narrative than we'll likely see in our actual future, the episode explores possibilities that aren't as far off as one might think.
Welcome back, my fledgling hackers! Hacking has a long and storied history in the U.S. and around the world. It did not begin yesterday, or even at the advent of the 21st century, but rather dates back at least 40 years. Of course, once the internet migrated to commercial use in the 1990s, hacking went into hyperdrive.
Although Christmas is a time to spend with family and be happy and full of joy, sometimes it's nice to pull a prank here and there, especially since many will not be expecting them.
If you're one who enjoys a good DIY project, or if you're just tired of paying exorbitant labor fees to have your vehicle serviced every 5,000 miles, changing your own oil can be a rewarding endeavor. Even though cars and trucks are becoming increasingly over-engineered these days, manufacturers generally see to it that the basic maintenance items can still be taken care of in your driveway with a few common tools.
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...
If you've been to a convention of any sort before, you know that there are good and bad panels, and that their inherent goodness or badness often has little to do with the actual content being discussed. That's because giving a panel is a skill that not everyone has. However, it is a skill that everyone could have! In this article, I'll tell you how to give a good panel on practically any subject.

One of the hardest, most intimidating parts of making your own Steampunk guns from scratch is the wooden stock of the gun. To be fair, it's probably the hardest part. It requires the most artistry, and is the easiest to mess up.
In the first part of this two-part guide, I covered cutting, grooving, beveling, making holes, and stamping/tooling. I hope you enjoyed that part, because we're pushing the accelerator to the floor and moving ahead at full speed!
I love making my own printed circuit boards. It really gives a professional look to a finished project, and having all the design files means I can whip up another batch whenever I need to. However, when I need to make, say, three thousand swarmbots or fill an order for a dozen PCBs, the traditional etching process can slow down the operation to a crawl.
Like theme music, I always feel that I need more fog in my life. Fog can be useful for many reasons—warding off smaller siblings from your bedroom, keeping curious hands out of your cupboard, and tricking your friends into thinking there's something horribly wrong with their vehicle. So, today we'll be making a very simple fog machine for small scale applications.

While many of the features in the iPhone 16 and 16 Pro series build on what we've seen in previous iPhone models, Apple has packed the 2024 lineup with iOS 18 and plenty of fresh upgrades worth considering.
Apple AirTags are super helpful for keeping track of your keys, backpack, and other frequently misplaced items, but there are some pretty clever things you can do with them beyond finding regularly used stuff.
There is a whole world of smartphone accessories out there, some of which are more quirky than others and don't get the recognition they deserve. But these sometimes strange, sometimes embarrassing products can really make life easier on your iPhone or Android phone.
Customization has always been the main draw of Android for me, but Apple has an impressive feature on iOS 16 that lets iPhone users create customized emoji wallpapers for their home and lock screens. While Android doesn't have something like that built-in by default, it's easy enough to make emoji wallpapers for your Android phone.
Rumors about the 2022 iPhone series stirred well before the iPhone 13 models were even released. While Apple remains quiet on the next big iPhone, as it always does, we're seeing more and more leaks and reveals for the iPhone 14 series as we lead up to a likely fall release.
Google dropped new features for its Pixel lineup of phones, and there's something here for everyone.
The new Material You theme engine with its fancy widgets is a sexy change for Android, but there's another new Android 12 feature that's more than just pretty colors and curves.
After years of speculation and rumors, Apple finally debuted AirTag, its tiny Bluetooth tracking device, during its spring 2021 event on April 20. Unlike with Tile trackers, there's no way to attach an AirTag to an object, but there's an entire market out there for AirTag accessories so that you can put one on your keychain, bike, or any other object that you can't just toss a naked AirTag in or onto.
The process of trying out new augmented reality and virtual reality hardware is as personal as it gets. Bottom line, if you can't directly try these immersive devices on, it's difficult to really understand the benefits they can bring to your life and work.
The iPhone doesn't stop at last year's excellent iPhone 12 lineup. Apple's been developing its iPhone 13 models for a while now, and there are a lot of rumors already with eight or nine months still to go until a release. This year, we're expecting four new models with similar sizes and features to 2020's offerings. If you want to know what makes the 2021 iPhones so different, we've got answers.
With just two microcontrollers soldered together, you can inject keystrokes into a computer from a smartphone. After building and programming the device, you plug it into a desktop or laptop, access it over a smartphone, and inject keystrokes as you would with a USB Rubber Ducky.
There are plenty of reasons to upgrade to the iPhone 12 mini. Maybe you want to take advantage of the improved camera system, or you're intrigued by the return to a smaller form factor. But one of its coolest features might be MagSafe, a completely different way to charge and accessorize your iPhone.
The iPhone 12, 12 mini, 12 Pro, and 12 Pro Max all have positive coverage surrounding their refreshed design, camera upgrades, and 5G connectivity. One piece of negative press you might've seen, however, is about the charger. Specifically, that there's a Lightning to USB-C cable in the box but no power adapter. That means you'll need a charger, and we've got some good recommendations for you.
Apple just released the first beta for iOS 14.2 to iPhone software testers today, Monday, Sept. 21. This update brings a new Control Center tile for Shazam music recognition, a redesigned Now Playing Control Center tile, and a new "People Detection" feature in Magnifier.
It is safe to say 2020 sucks. With the coronavirus pandemic and civil unrest, things haven't been great. But beyond impacting your emotional state, that upcoming phone you've been waiting for has likely had its release date pushed back.
