Fireworks are the best part about the Fourth of July and other celebrations, but they can easily cause accidental injuries. It's both safer and more fun to set them off remotely, so we'll hack some standard fireworks with nichrome wire, a relay, and an Arduino to ignite remotely over Wi-Fi using any smartphone or computer.
When joining a new network, computers use the Address Resolution Protocol to discover the MAC address of other devices on the same network. A hacker can take advantage of ARP messages to silently discover the MAC and IP address of network devices or actively scan the network with spoofed ARP requests.
A relay is an electrical component that works like a light switch, where it's turned on or off with an electrical signal. By connecting a relay to a Wi-Fi connected microcontroller like an ESP8266, you can build a connected switch that can be controlled from the web browser of any device connected to the same Wi-Fi network — all for just a couple of dollars.
Your iPhone is just that — yours. Why should your home screen look like everyone else's? While iOS, and by extension, Apple, famously locks its users into its way of doing things, there's a lot more room for customization than you'd think. Before you make the switch to Android, you might want to see what you can do with the iPhone you already have.
Last year's augmented reality investments roundup was impressive. And in 2018, the dollars flowing toward AR haven't decreased, as venture capitalists and strategic investors continue to aggressively fund AR startups at a rapid pace.
Waking up your Apple Watch to see "your heart has shown signs of an irregular rhythm suggestive of atrial fibrillation" might come as a shock. While your watch can send you warnings if it detects a fast or low heart rate, those messages are pretty vague, while the abnormal arrhythmia alert can downright scary. So what should you do if you receive one of these AFib notifications?
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?
Mystery is a tricky thing. Used correctly, it can give onlookers the impression that wondrous and perhaps valuable things are afoot. However, once the veil of suspension of disbelief is removed in any significant way, that same mystery can quickly turn into not just skepticism, but outright anger at what may have seemed like an attempt to dupe trusting onlookers.
I've had a few days to live with the Magic Leap One, and it's time to finally weigh in with some thoughts as someone who has been tracking this company from the beginning, for almost five years now.
Most users don't realize how much valuable data is in their network traffic. With a few simple tools, an attacker can quickly pick out cookies, passwords, and DNS queries from a macOS device as it covertly streams the victim's network traffic to the attacker's system. Here, we will cover two methods for analyzing packets flowing from a Mac.
I was in college, and my 15-inch Sony Vaio laptop was my prized possession. It was my first PC and probably the most important thing I brought with me to my dorm — it was both how I completed my assignments and my primary source of entertainment. How could it turn its back on me in my time of need?
Magic Leap CEO Rony Abovitz doesn't engage in tweetstorms often, but when he does, those tweets are bold, exceedingly confident, and there's usually a strong takeaway regarding what the company is or isn't doing. But on Thursday, Abovitz's latest tweetstorm sent an unusually flustered message: We promise, the magic we're telling you about it better than anything you've seen on video.
One of the primary factors that separates an augmented reality device from a standard heads-up display such as Google Glass is dimensional depth perception. This can be created by either RGB cameras, infrared depth cameras, or both, depending on the level of accuracy you're aiming for.
Whether you're new to Android or you just haven't kept up on the app scene lately, we hand-picked over one hundred essential apps that are all designed to improve your experience. From custom launchers and icon packs to weather apps and file explorers, there's something for everyone in this list.
Blowing dust and fungal spores are creating a public health problem that could be just a slice of what's to come with climate change.
When you have an infection, a doctor prescribes antibiotics to make the bacteria that causes it disappear. Sounds like a good idea, but the disappearance of microorganisms that have inhabited humans for millennia could be driving rising numbers of serious illness and debilitating conditions.
While some researchers look for drugs to treat HIV, other scientists delve deep into the virus itself for answers on how it causes infections.
Windborne microbes shifting in the snows of the great ice sheet of Greenland may be able to neutralize some of the industrial contaminants oozing out of the melting ice.
Way back, life on the range was tough and unforgiving for a HoloLens developer. Air-tap training was cutting edge and actions to move holograms not called "TapToPlace" were exotic and greeted with skepticism. The year was 2016, and developers had to deploy to their devices to test things as simple as gauging a cube's size in real space. Minutes to hours a week were lost to staring at Visual Studio's blue progress bar.
With new diet and health claims coming at you everyday, it's sometimes hard to know what to believe. Well, here's a bright spot: A pair of studies confirm that whole grains are healthy for you, and for the diversity of microbes living in your gut.
Six people have died from fungal infections in Pittsburgh hospitals since 2014—that fact is indisputable. The rest of the situation is much vaguer. A lawsuit has been filed against the hospitals on behalf of some of the deceased patients, alleging that moldy hospital linens are to blame. While the lawyers argue over who's at fault, let's look at how this could have happened.
Humanity is standing on an infection precipice. As antibacterial resistant grows, we're running out of options, and a recent scary case of total antibiotic resistance is a frighting view of our potential future. In the end, it was septic shock that took the life of a 70-year old woman with an incurable infection. One of few such cases in the US, her death could nonetheless be the shape of things to come.
To shine light on the future of the relationship between humans and viruses, a team of researchers from the University of Oxford looked into the dim and distant past.
When the HoloStudy Demo app for HoloLens came out in September, it was a pretty impressive start to what could be a very valuable science tool for education. Now, Moscow-based HoloGroup, makers of HoloStudy, started an Indiegogo campaign to improve their modular teaching app.
Apple caught a lot of flak for removing the headphone jack in their iPhone 7 models, but they definitely got the last laugh when preorders with a delivery date of September 16 sold out within minutes. Headphone jack or not, the iPhone 7 and 7 Plus are still highly desirable products, and consumers have confirmed this by voting with their wallets.
If you think that "pawpaw" is just an affectionate name for your grandfather or a cute way of talking about your cat's feet, you're missing out on one of the most interesting fruits out there.
What's your top pet peeve? Open-mouthed chewing? Nail biting and knuckle cracking? The sound of silverware scraping? Or perhaps it's a bigger behavior, like leaving the toilet seat up?
When attempting to gain access to a server, there may come a point when you need to get around file upload restrictions to upload something. If we can find a way to get around the restrictions, then we can upload anything we want to the server, effectively compromising it. That is what we'll be doing here today, so let's get started!
When a migraine strikes, it can be crippling. Intense and sharp pain not only at the temples, but radiating throughout the entire head; feelings of nausea and digestive discontent; an unbearable aversion to light, sound, and even the smallest of movements.
If you took a big step back and really looked at the world, you'd see how downright silly our nations look when they put up fences to separate themselves from one another. Creatures big and small roam free while respecting each other's space, but humans create borders and physical barriers to delineate their cultures.
There's nothing worse than biting excitedly into your indulgent restaurant-style burger only to find a soggy mess of a bun on your plate. The conundrum of keeping a patty moist but bun dry has perplexed home cooks and chefs alike, and even top burger joints are guilty of soggy-bun syndrome.
Welcome back, my hacker novitiates! A short while ago, I introduced you to regular expressions. Regular expressions are a language that is particularly useful for finding complex text patterns in streams of data.
If you've already read the first part exploring what geniuses actually eat as opposed to what the rest of us are told to eat for brain health, you've noticed that there are some big discrepancies. Instead of favoring healthy, wholesome foods high in antioxidants, lots of high-achieving types tend to go for caffeine, sugar, and processed foods. One notable health habit practiced by many: eating breakfast.
It may sound irrational, but I bet a lot of you actually avoid doing any work at work—but not on purpose. You might be simply struggling with motivation, or you might just be overdosing on the caffeine. Whatever the issue, getting focused takes lots of time and effort.
Welcome back, my novice hackers! This next subject might seem a bit obscure, but I promise you, this lesson will benefit you significantly either as a hacker or system admin. This tutorial will cover what is usually referred to as a regular expression, or regex for short.
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!
I've never had a black eye, but I was in a car accident that turned my entire ear dark purple a few years ago. Believe me; it was enough to get more than a few funny looks.
If you're going to build yourself a water gun to cool down this summer, or maybe just a useful water pump, you'll need some check valves. However, the most expensive parts of a water pump or DIY super soaker are usually the check valves. So, let's make some from scratch for as little as $0.35 each.
Back in 2007, YouTube user HouseholdHacker posted a parody video on how to make a high-def speaker for under a buck. MythBusters took on the challenge and busted it.
I obviously do a lot of Steampunk projects, but there are a ton of things out there that I haven't tried yet. So, in an effort to broaden my horizons, I recently taught myself how to use Arduinos, which I plan to incorporate into some of my future Steampunk builds.
