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...
When I left off on our last hack, we had hacked into the ubiquitous Windows Server 2003 server by adding ourselves as a user to that system so that we can return undetected at any time. The problem with this approach is that a sysadmin who is on their toes will note that a new user has been added and will begin to take preventative action.

In this video, Sierra Snowboard gives us some tips on how to select the snowboard that's right for you. Each board comes in a number of different sizes, and most boards come with a size chart specific for that board. These charts can be vague, but are good starting points for selecting your size. One thing to consider is your bossy type. The weight of the rider is the primary factor in selecting the size of a snowboard. You'll notice that the height of a rider is not listed on a size chart.

Have you ever noticed that when you put your iPhone to sleep, it takes an extra second longer than it probably should for the screen to go black? It's a bit strange and forces you to wait another moment until your iPhone locks. But most of you can avoid the small delay entirely by just changing one setting.
While there is a lot to love about Apple's latest suite of iPhone models, the real draw comes down to the cameras. The iPhone 11, 11 Pro, and 11 Pro Max all have killer rear camera systems, but the front camera was also improved. Apple claims Face ID works at more angles than before in these models, which begs the question: can you unlock your iPhone when it's flat on a table?
After months of waiting, the iPhone 11 is here. At an event in Cupertino, Apple unveiled the iPhone 11, 11 Pro and 11 Pro max. You probably have a lot of questions after reviewing the specs sheet, including wanting to know more about the IP68 rating that all three phones have. We're here to clarify.
After the limited initial release of the massively popular game on the Android platform, many users have been stuck waiting to play Fortnite. That's because, initially, Epic Games only released the game to Samsung Galaxy devices, and asked non-Samsung users to join an invite list. Well, the wait is finally over.
The day has finally arrived — Samsung has unveiled the Galaxy S9 and S9+. Apart from minor upgrades, the two might not appear to be much different from last year's S8 and S8+, but that's not necessarily a bad thing. One feature that hasn't changed is the Galaxy's IP68 water-resistance rating. That's a great score, but it begs the question — what does that number really mean?
Just yesterday, Google announced that it is banning all apps that contain any form of lock screen ads. Today, they posted a list of the Best Apps of 2017 for the Play Store. Given the new policy of cracking down on apps with advertisements on the lock screen, you wouldn't expect to see one of those in the list of top apps. Unfortunately, that's exactly what happened — Google is promoting obvious adware in their list of best apps.
The Galaxy S8 Oreo Beta has been out for just over a week now. Over that time, we've taken a look at some of the best new features and improvements. One area of smartphone software that never gets much love in updates is the lock screen.

In case you didn't catch the big event in Cupertino, Apple just unveiled two of the most cutting-edge phones ever made — the iPhone 8 and the iPhone X. Out of the many glorious specs that were rattled off on stage, one stands out for being just a little confusing: Both models are rated IP67 under the IEC standard 60529.

In this article, I am most likely going to humiliate myself by showing you all the horrible hashtagging I am wont to do. When it comes to hashtags, well, everybody knows if you desire any chance at all of getting noticed on Instagram, you got to hashtag.
If OnePlus co-founder Carl Pei was trying to be slick about using the new OnePlus 5 phone — especially before its speculated summer release — well, he didn't do that great a job of hiding it from us.
The OnePlus 3 and 3T are a pair of phones which allow you to do practically anything you want, because OnePlus is such a developer-friendly company. They almost always release kernel sources, and their phones sport an unlockable bootloader that doesn't void the warranty. But while their software is certainly solid (miles ahead of Samsung's TouchWiz), it still has room for improvement.
The rumor mill surrounding the iPhone 8 is churning this week, and not necessarily in a good way. Yesterday, we learned Apple may be leaving the 3D camera out of the next big iPhone to keep the phone on schedule. Today, rumors allege the 10th-anniversary edition of Apple's smartphone may not ship with Touch ID embedded under its display.
During the last few months, WhatsApp's Google Play Store ratings have been tanking—all the way down to an average of 3.4 stars from the instant messenger's usual average of 4.1.

For most Android phones, the system clock is set using a protocol called NITZ, which relies on a connection with your carrier to ensure that the time stays in sync. The trouble here is that this feature won't work when you're outside of cellular range, and a lot of times, the carriers themselves have technical difficulties that can result in your phone's clock being minutes or even hours out of sync.
The art of taking secret photos is one that requires keen awareness and skill. Not only do you need to ensure that your subject remains oblivious, but you also need to make sure that no one near you notices what you're attempting to do. It's great when you buddy is acting a fool, but sucks when they stop their shenanigans when they notice you pulling out your camera phone in an effort to evade your picture.
The Samsung Galaxy S6 includes a pretty nifty feature known as "Gesture wake up," which lets users wave their hand over their locked display to wake it, making those periodic notification checks from the lock screen a lot more simple than having to press the power or home key every time.

You've been there. Those precarious few seconds between dropping your expensive smartphone right on its face and reaching down to survey the damage.

If you're like me, then you were a little disappointed after updating your Nexus 7 to KitKat and realizing that not much has changed. The old Jelly Bean look still occupied your home screen, and there wasn't really anything noticeably new overall. All of that waiting and anticipation only to be left high and dry.
Just like the HTC One Google Play Edition, the recently released Samsung Galaxy S4 Google Play Edition ditches the manufacturer's UI in favor of a pure Google experience, i.e. AOSP, but is also optimized specifically for the device's hardware.
If the Nexus 7 wasn't your first Android tablet, you may have noticed something different with the user interface when compared to other Jelly Bean tablets. You may not know exactly what it is off the top of your head, but it's there.
Having trouble getting a strong Wi-Fi signal on your Samsung Galaxy S3? Does the signal drop out on you when changing rooms? Frustrating, isn't it?
