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.
Whenever a friend borrows my Samsung Galaxy S3 to browse the web or make a quick call, I always pause to make sure there's nothing incriminating on it. I'm no superfreak, but some of my friends are, so I have more than a few photos on my device that I wouldn't wish upon anyone. I like to avoid these kinds of looks.
Last time, I showed how to start putting together an AC arc welder from scavenged microwave parts, focusing on the transformer modifications. Now, I'll show you how to finish up your DIY stick welding machine by fixing up the electrical system and performing the finishing touches.
Thought I would cross-post a piece I did a while ago.

The vast majority of people involved in Steampunk are interested in history but, like with science, there's something about history that we don't talk about very often: The holes.
There is never a dull moment when it comes to the internet. You can find practically anything you want, whenever you want it. To make that process even smoother and more direct, companies have created a bunch of apps designed to help you find what you're looking for, or enlighten you on a subject you may not have even thought of yourself.
"You can never know too much" is a saying you hear all the time. Funny thing is, I have no idea where it originated, and neither do most of the people who continually say it. Nevertheless, it's a statement that very few would argue with.
I don't know how many of you had this experience in your youth, but when I was a kid, I used to actively think about what would happen if I suddenly woke up in a fantasy land, or were to pass through a portal into another space and time. I knew it wouldn't really happen, but when you're a kid, these can be important issues to you. So I slept with my glasses on every night, just in case. Photo from George Pal's The Time Machine.
Back in 2010, iOS developer Daniel Amitay developed a camera security app for iPhones that used an unlock screen almost identical to that of the iPhone.
A travelator, also known as a moving walkway or moving sidewalk, seems like a tricky thing to build in Minecraft, especially when it's zigzagging, but there are really simple autowalks out there (like this one).
In general, hacking and information security is not just one discipline, but a number of them, and today we will look into some of the networking concepts.

Your iPhone has hidden apps that work behind the scenes to filter SMS messages, trust computers, deal with payments, test ads, and perform other actions. You won't find any of them in your App Library, but there are tricks you can employ to unlock and use some of these secret apps.
The private automobile has been an intrinsic part of our lives for around a hundred years. But over the last decade, car sharing has gained a very small but growing part of the mobility market. The more recent rise of companies like Uber and Lyft is witness to a more dramatic shift in mobility and car ownership. Private vehicle ownership to a transportation-as-a-service model has already started, and high capability SAE Level 4 vehicles will complete this trend.

For whatever reason, you may want or need to remove multiple posts from your Instagram grid. If you only have a couple to hide from the public, archiving or deleting posts one by one is fine, but there's a much faster way when you have tens or even hundreds of Instagram posts to purge from your account.
It's super easy to add filters, adjust levels, and crop images using the default photo editor on your smartphone, but there's rarely any built-in tool for removing the background in a photo. A third-party app can help isolate people and objects in your pictures, and we've found a free one that's easy to use, works with high-resolution images, and is available for Android, iOS, iPadOS, and the web.
The year leading into fall is turning out to be packed with a flurry of augmented reality activity. Most notably, TikTok is adding another major weapon to its AR arsenal. Also on deck are the powers of Hollywood horror in the form of an innovative approach to AR marketing that uses sounds.
The march to the mainstreaming of augmented reality can sometimes seem slow, but this week things picked up in earnest.
Already among the leaders in AR development tools via its Unreal Engine, Epic Games has added another tanky weapon to its arsenal.
When Microsoft unveiled Mesh a couple of weeks ago, the move revealed a major part of Microsoft's next steps toward dominating the augmented reality space, particularly with regard to enterprise customers.
A lot of digital ink has been spilled heaping scorn on Magic Leap. Much of that media schadenfreude was due to what some believed were unmet promises versus some of the early hype around the product. Others just seemed to be rubbed the wrong way by the startup's Apple-esque secrecy and penchant for attempting to coin new terms and frameworks for things that were, mostly, already in play.
The new iPhone 12, 12 mini, 12 Pro, and 12 Pro Max are equipped with some great cameras, but not perfect cameras. The ultra-wide lens is known to cause distortion at the edges of the frame, so people and objects look slightly warped. To compensate for the skewed edges, Apple incorporated "Lens Correction," but that fix isn't perfect either.
Since launching Google Lens as a a Pixel-exclusive feature in 2017, Google has not only expanded the availability of the tool to Android and iOS, but also built upon its functionality. Now, in addition to translator, tip calculator, personal shopper, and tour guide, Google has added math tutor to the job description for Google Lens.
Just because your phone has a high-resolution screen doesn't mean it will play videos at their highest resolution. Most streaming services, including Netflix, use a DRM system known as Widevine for media in their Android apps. But even if your phone has Widevine support, content will be limited to non-HD if your specific model hasn't been whitelisted by Netflix.
When it comes to cybersecurity, one layer isn't enough. A complex password (or one created with a password manager) does a good job of protecting your data, but it can still be cracked. Two-factor authentication strengthens this by adding a second layer of security, giving you even more protection against online threats.
Does TikTok scare you? Trust me, I get it. It's a strange, unfamiliar place to those of us not accustomed to its ways, populated by teenagers and college students with their own subcultures, memes, and humor. But here's the thing: TikTok has something for everyone, you included.
Choosing a movie to watch at home can be incredibly difficult when you don't already have one in mind. But there's a shortcut for your iPhone that can make it easier to browse your streaming media services for something good to play. More specifically, it lets you browse Netflix and Amazon Prime at the same time.
One of my favorite perks of this job is the opportunity to try out all the big flagship phones each year. Whether it's rating their suitability for a particular use-case or just entering their specs into our comparison tool, we have to get our hands on all major phones released in the US. We pride ourselves on being fair in our reviews and roundups, but that doesn't mean we don't have preferences.
We've already shown you our favorite new action games that have come out this year, but now it's time to share our all-time top ten list. These games are available for both Android and iPhone, they don't have intrusive ads or freemium schemes, and most importantly, they're all completely free to play.
With a tiny computer, hackers can see every website you visit, exploit services on the network, and break into your Wi-Fi router's gateway to manipulate sensitive settings. These attacks can be performed from anywhere once the attacker's computer has been connected to the router via a network implant.
Magic Leap has done a great job of aggressively releasing new apps, software updates, and major franchise tie-ins. But aside from all the creative and entertainment apps, what's it like to use one of the apps the company hopes you'll use every day?
Smartphones have put an end to camcorders. If you want to capture memorable moments in high quality, look no further than that technological marvel in your pocket. Recent Galaxy phones are shining examples of how far we've come — but the more capable a camera gets, the more complicated things can be.
Websites and web applications power the internet as we know it, representing a juicy target for any hacker or red team. TIDoS is a framework of modules brought together for their usefulness in hacking web apps, organized into a common sense workflow. With an impressive array of active and passive OSINT modules, TIDoS has the right instrument for any web app audit.
Auditing websites and discovering vulnerabilities can be a challenge. With RapidScan and UserLAnd combined, anyone with an unrooted Android phone can start hacking websites with a few simple commands.
ARP spoofing is an attack against an Ethernet or Wi-Fi network to get between the router and the target user. In an ARP-spoofing attack, messages meant for the target are sent to the attacker instead, allowing the attacker to spy on, deny service to, or man-in-the-middle a target. One of the most popular tools for performing this attack is Ettercap, which comes preinstalled on Kali Linux.
Encrypting payloads and encoding stagers are more effective against macOS than one might think. It's very easy to evade VirusTotal and macOS antivirus software using a few simple tricks.
A powered-off MacBook can be compromised in less than three minutes. With just a few commands, it's possible for a hacker to extract a target's password hash and crack it without their knowledge.
