The big fireworks day is almost here, but most of you are limited in what you can do when it comes to celebrating the Fourth of July with a bang. Unless you live in a dry area prone to wildfires, one type of fireworks you can probably still legally buy are sparklers.
Mixing water and electricity is extremely risky and potentially lethal, yet that's exactly what I did with the Scariac. In its simplest form, the Scariac is just a glorified version of two wires in a bucket of water, but it's actually one of the cheapest power controllers you can make.
Wet shoes are uncomfortable, no one can deny that. Just think about walking around with soaking wet footwear ... and each squishy step you take. Makes you cringe, doesn't it? It can happen in heavy rain, at the beach, or from an unforeseen puddle on the street. And while you can't always avoid soggy shoes, you can rest easy knowing that the next time this happens to you, you know the secret trick to drying your shoes faster without damaging them with excessive heat.
If the interconnected worlds of blockchain, Bitcoin, and cryptocurrencies scare you a bit, you're not alone. Thanks in part to the extreme and seemingly random fluctuations in the value of Bitcoin over the past three years, more than a few developers and investors are wary of the cryptocurrency revolution and its ties to blockchain development.
Wi-Fi networks come in two flavors: the more common 2.4 GHz used by most routers and IoT devices, and the 5 GHz one offered as an alternative by newer routers. While it can be frustrating to attack a device that moves out of reach to a 5 GHz Wi-Fi network, we can use an Alfa dual-band adapter to hack Wi-Fi devices on either type of network.
The holidays are here. From the week of Thanksgiving until the end of the year, retailers will be offering massive discounts on your favorite items. So if you're looking for smartphone accessories, this is the time to buy. From Walmart to Best Buy, there are deals everywhere on a host of items.
You're minding your business when your Apple Watch taps you. To your surprise, the watch claims your heart rate dipped abnormally low. The news might come as a shock — especially if you have no history of a heart condition — but before you panic, you should take the time to fully understand what this alert is really saying and what you can and should do about it.
Your Apple Watch sends you notifications from friends, family, and the apps that are important to you. Occasionally, however, the watch may scare the heck out of you with a notification warning of an abnormal, elevated heart rate. If you have no history of heart conditions, this alert might come as a shock. Why do you have a high heart rate, and what are you to do with the information?
If you've ever been on the receiving end of a threatening phone call, you'll immediately know the value in being able to record phone conversations on your iPhone. Beyond that extreme example, however, recording calls is still an extremely useful feature to have for important conversations like business meetings and verbal agreements, and it's totally doable with a third-party app.
Before, the only way to really tell how your iPhone's lithium-ion battery was performing was to use tools such as Geekbench and Battery Life, but now Apple has included some quick battery health checks right into iOS 11.
So, you've gotten (or are getting) a shiny new iPhone 8 or 8 Plus. Congratulations! It's got great new features including the new A11 Bionic chip, wireless and fast charging, and portrait lighting. And let's not forget a much better battery ... right?
Earlier this year, NASA reported on findings that might point to water, and microbial life, on moons orbiting Jupiter and Saturn. Named Europa and Enceladus, those moons contain large oceans under their icy surfaces, which many speculate could hold microbial life.
To hack a Wi-Fi network using Kali Linux, you need your wireless card to support monitor mode and packet injection. Not all wireless cards can do this, so I've rounded up this list of 2019's best wireless network adapters for hacking on Kali Linux to get you started hacking both WEP and WPA Wi-Fi networks.
For some of us, winter puts the brakes on apps like Pokémon GO since smartphone screens usually only respond to bare fingers. Nobody wants to be that guy who caught frostbite chasing a Sneasel. When you use normal gloves, the display's sensor simple doesn't activate, so that doesn't help any. Fortunately, several options for touchscreen-friendly capacitive gloves are on the market to help you through this last blast of winter.
It won't come as a surprise to hear that your cell phone, tablet, and laptop are loaded with bacteria and other organic material. While most of these bacteria are harmless, there are good reasons to reduce the capability of your mobile devices to infect you—or other people.
You just sat down, coffee in hand, and the day is ready to start. Now that you have taken a few sips, let me pose a question: What is living in that coffeemaker of yours? The answer might make you dump that coffee down the drain pronto.
As a former repair tech, I've heard the same reasons over and over as to why people opt not to purchase phone insurance. Some cite the cost—why pay extra every month for insurance when you're careful with your phone? Deductibles are expensive, so why not just spend that money on a repair instead of getting a refurbished phone as a replacement?
In my days as a hardware tech, I often came across motivated do-it-yourselfers who watched a video or two on how to repair a phone and thought that they'd give it a go. More often than not, they failed miserably and damaged their phones (and wallets) even more in the process.
My husband's and my daily schedules are constantly changing. Frankly, it's complete chaos sometimes, so I can't plan to have elaborate dinners on the table at six o'clock every day. And by the time we actually get to eating in the evening, we've become so hungry that our moods have taken a nosedive.
Gas stations may be convenient for travel snacks, but the cost of shopping there sure can add up. If you're looking for easy, on-the-go snacks that fit into your travel budget, look no further. We've got 12 kid-friendly, portable food ideas you can make before leaving on your journey. You'll be amazed by how much money and time you will save with these satisfying travel snacks.
It's truly amazing how far smartphone camera hardware has come in such a short period of time. It took roughly 5 years to advance the image processing capabilities from a pixelated mess to the crisp and clear photos we can take today. This reaches well beyond the megapixel spec race, since camera modules these days sport vastly improved optics, wider aperture, and even larger pixel sensors that capture more light.
If you've got a birthday party to plan for a young budding scientist coming up, a little nitrogen should do the trick. In this project, I'll show you 10 "super cool" tricks with liquid nitrogen that you could try, but probably shouldn't!
Lurking inside your old junk microwave is an abundance of useful parts that can let you melt metal, spot weld, and make electrifying Jacob's ladders. You can even make a powerful AC arc welder, perfect for making hard-to-solve puzzles and even makeshift weapons for the zombie apocalypse.
Ever see those cars so covered in dirt, dust, and grime that someone writes "Wash me" on it using their finger? Well, for those cars' sakes, as well as cases less extreme, a word of advice: procrastination is not a solution — it can only compound the problem. Self-cleaning cars are the stuff of the future, not the present, and your car needs attention now.
There are lots of people who want to stay anonymous online, and lots of reasons they want to do this. Staying anonymous on the internet isn't easy, and it's probably possible to trace almost anyone with enough time and resources. A lot of people think that they're completely secure with just one method of cover. For example, a lot of people thought anyone using the Tor network was nearly untraceable, but then things like this often cast doubt on just how secure these networks are. Unless you ...
Every now and then, an iOS secret surfaces that makes me wonder, "How am I just learning about this?" I remember the first time I found out how to delete numbers in the Calculator app, and when I discovered you could bulk-move apps around the Home screen. Now, there's another tip to add to the list: a hidden iOS app whose icon you quite literally can't find unless you know where to look.
After months of back and forth, ZTE is finally making their return to the United States. The last phone the Chinese company released here was the Axon 7 Pro, a low priced flagship phone that competed well against the OnePlus 3 and 3T at the time. Its successor is the Axon 10 Pro, which adopts the same strategy.
If you're looking to keep your conversations private, look no further than Telegram. Its cloud-based chats are secure and its optional end-to-end encrypted chats even more so, but you can't really prevent someone in the conversation from sharing your messages. However, you can lessen that chance by taking back your messages, deleting them for both you and the other end of the discussion.
Samsung isn't known for its timely rollout of major Android updates, and Android 9.0 Pie won't be an exception. If we go by their Oreo update timeline, we can expect Android Pie to officially touch down for the Galaxy S9 and S9+ sometime around November, with the final version rolling out the around the first quarter of 2019. But a leaked version of the beta has already hit the internet.
Even though your iPhone's Camera app is fast and easy to use, its default settings prevent you from immediately accessing any other shooting mode aside from "Photo" with "Live Photo" on and no filter applied. But there is a way to make the Camera app remember what you prefer the next time you open it up.
Over the years, Magic Leap's long-cultivated shroud of mystery led some onlookers to buy into the company's dream before even trying the device, while for others, the secrecy seems to have stoked the kind of resentment and overcorrecting critique usually reserved for the mighty Apple.
Using just a small sticky note, we can trigger a chain of events that ultimately results in complete access to someone's entire digital and personal life.
In October of 2017, Mathy Vanhoef released "Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2." This paper demonstrates a way to decrypt traffic on practically any WPA2 network, the most commonly used form of wireless security (seeing as all other forms of Wi-Fi encryption have already been broken). Practically all of the network-connected devices we use will need to be updated in some way in order to protect against this vulnerability, each of them in a different way.
Cruise Automation, the driverless car startup General Motors (GM) bought for $1 billion in 2016, is readying a formidable fleet of robo-taxis for rollout in cities throughout the US. But when it comes to details about how the company plans to realize these lofty goals, it's been fairly tight-lipped.
Kuru is called the shaking disease, its name derived from the Fore word for "to shake." Caused by an organism that infects the part of the brain that controls coordination, people afflicted with kuru shake uncontrollably.
Mobile gaming still isn't on par with video game consoles or PCs, but we've come a long way from Snake. Modern games running on the latest smartphones boast downright impressive graphics—even more so when you consider how compact the system has to be in order to fit in people's pockets.
Pumpkin carving and decorating is a favorite October pastime. After you've carved an amazing design or face into a pumpkin or two, you want to show it off through your window or set it out on your porch for the neighbors to see.
Staying healthy is a progressive challenge we all face throughout our lives, and figuring out just how to do that can be a challenge when it's not your job. For doctors, however, it is. Here's how they keep themselves healthy day to day.
Hard-boiled (also known as hard-cooked) eggs are notoriously easy to mess up. We've all ended up with tough, rubbery egg whites and overcooked yolks that have that unappetizing gray-green ring around the edge. An ideal hard-cooked egg has a firm yet tender white, while the yolk is creamy and well-done without being mealy.
When we got our first look at US Army soldiers testing Microsoft's modified HoloLens 2 last year, it still looked very much like the commercial edition, with some additional sensors attached.
