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.
Welcome back, my greenhorn hackers! I've been writing these Linux tutorials in an attempt to fill the void in the education of some aspiring hackers into the Linux operating system. There is a lot to know, and in this tutorial, we'll look at Linux file permissions. Step 1: Checking Permissions
A spare key is one of those things that never seems like a huge deal until you need it. If you've ever lost your keys, had them stolen, or locked yourself out of your house or car, you know how difficult and embarrassing it can be trying to get your door open.
Glow sticks, a popular favor at parties and outdoor events, and a must-have on Halloween, can be traced back to the United States Navy in the mid-1960s. The military desired improved visibility during night operations, and glow sticks, with their small-size portability and lack of batteries, were a perfect tactical solution.
At one point in the '90s, about fifty percent of the CDs produced worldwide had an AOL logo. About fifty percent of the CDs in my home still have that AOL promise of 500 free hours on them. Though they never got me to join their internet service, I did get a lifetime supply of coasters. Thanks to the rise of high-speed internet access and bigger and better hard drives, there's no reason for companies to snail mail any more of those obnoxious plastic discs.
The iPod changed the music and electronics industries when it was first introduced way back in 2001. It is credited with ushering in the age of "connected devices," and has held a huge market share of around 70% for years. At the height of its popularity, the iPod made up almost 50% of Apple's revenue. Now that the smartphones and tablets we use every day have the ability to store and play music, the iPod's glory days are over. Nevertheless, there are millions of people who still use them, an...

Here's how to make dry-ice at home, or wherever you feel like it! All you need is a pillow case, and a CO2 fire extinguisher.
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.
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 was recently a case that came to national attention where a gentleman was arrested at an airport for having a watch that looked like a bomb, among other things. As it came out, the watch was, in fact, not a bomb, and the man was just an artist who was probably trying to make a statement of some sort. Well, that message was lost amongst the hail of people shouting that either he had been stupid for bringing that watch on the plane and so deserved to be arrested, or that it's a free count...
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.
Steampunk is a tremendously interesting phenomenon because of its reliance on science fiction, and fiction in general. Steampunk can arguably be broken down into two categories: the fiction, and the aesthetic. Sometimes these categories cross over, but they're often more distinct than most people suspect; that said, the aesthetic is firmly based in works of fiction.
Before I really get into this article, it's important to note that you do not need a Steampunk persona (or "steamsona") in order to be a Steampunk, or wear Steampunk clothes. Some people like to pretend to be a different person when dressed up in Steampunk clothing, but that is entirely optional, and only to be done if it appeals to you. That said, even if you aren't actually acting as your character, it may still be helpful to have one in mind when putting together an outfit. Personally, I'v...
War leaves a lot of stuff behind. Torn families, delegitimized institutions, mass graves, and unexploded ordinances litter the post occupation landscape. Whether or not you have driven the imperialist out, or are still in the phase of armed resistance, you will need the ability to safely diffuse bombs. My bomb defusing Silvia-bot can do it all. She can catch grasshoppers, cut wires, collect samples, tase enemies and even play chess! Materials
In my first installment in this series on professional hacking tools, we downloaded and installed Metasploit, the exploitation framework. Now, we will begin to explore the Metasploit Framework and initiate a tried and true hack.
The best chemistry experiments are those you can perform with items already laying around your house. With only some sugar, salt substitute and an instant cold pack, you can make your very own gunpowder! Being able to make homemade gunpowder without a trip to the store can be a lifesaver, no matter if it's just for testing out a Civil War-era musket, blowing up stubborn tree stumps, or preparing for battle when imperialists overrun your country.

If all things go well, you'll only have to take your road test once. That's the goal: to ace your test on the first try and then start driving on your own. Granted, it's a nerve-racking experience, but keep in mind that the California Department of Motor Vehicles wants you to pass. So much so, they give you the examination answers ahead of time! All you have to do is study.
Seventeen years ago, Apple released iPhone, the first mainstream consumer phone with a touchscreen as its main typing input method. Apple has been perfecting its onscreen keyboard for almost two decades, and it's built with some fantastic features that make typing faster and easier. But it's easy to overlook some of these features, so here are some tips and tricks you need to be using if you aren't already.

Toymaker Lego has been on board with building AR into its playsets and mobile apps since the launch of ARKit.
One of the easiest ways to change up your Android experience is by swapping out the stock launcher with a new one. The word "launcher" is Android lingo for "home screen app," and it's a common term because of how easy it is to switch to a new one. So if you're looking to revamp your home screen, this guide's for you.
Google switched to gestural navigation in Android 9, and in removing the back/home/recents buttons, they were able to greatly reduce the size of the navigation bar at the bottom of the screen. However, there's still a white line, aka "The Pill," taking up space to show you where to start your gestures.
The latest generation of Spectacles aren't AR smartglasses per se, but Snap is intent on demonstrating that the wearables are capable of storytelling powered by augmented reality.
Google's version of Android is best described as AOSP with extra features. But while the Pixel's UI is rightfully praised for its simplicity, those "extra features" aren't as numerous as they are on other OEM skins like Samsung's One UI. Case in point, there's no real system-wide audio EQ.
One of the underrated components of the Galaxy Note 20 series is its usage of Gorilla Glass Victus. Think of this as Gorilla Glass 7, the latest innovation from Corning. And this release is a big deal, delivering protection without sacrifices.
