Among the younger generation, Roblox rivals major titles like Minecraft as one of the most popular online games out there. In fact, it's common to hear children tell new playmates to "friend me in Roblox!" so they can play together online. There's nothing inherently sinister here, but with all the online interaction, kids' safety becomes a factor.
You don't need an obsessive ex stalking you to benefit from the ability to record calls on your iPhone in a pinch. Besides protecting yourself from nefarious intent, recording important conversations like verbal contracts and agreements can help you cover all your bases and ensure you're insulated from any potential liabilities that may appear down the road.
When it comes to busted smartphones, liquid damage ranks right up there with shattered screens as one of the most common issues owners have to deal with—as well as the most embarrassing. Thankfully, though, with the rise of waterproof phones such as the Samsung Galaxy S7 and even the iPhone 7, this is becoming less and less of a worry. But not everyone has a waterproof device.
Oh no... your precious iPhone is in shambles. Maybe you shattered your screen after a crazy night of celebrating, or maybe your two-year-old jabbed a toy into your iPhone's charging port, completely destroying it in the process. Now what? Do you take it to a repair shop, or go to an Apple Store to have it fixed? This brief article will help you weigh your options.
Welcome back, my budding hackers! People often ask me, "Why are you training hackers? Isn't that illegal?" Although I usually give them a short version of this post, there are MANY reasons why YOU should be studying hacking.
People tend to skip toasting nuts in recipes or before adding them to salads because it seems time-consuming and the margin for error is high. However, skipping this step is a big mistake. Why? Because when you skip toasting your nuts (go ahead, you can laugh, we're all doing it), you sacrifice flavor and texture. And not just a little flavor, but a lot. Alton Brown recommends wok-frying peanuts before making your own nut butter for this very reason.
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.
As you know, it's impossible to be a Steampunk without a pair of goggles. In fact, there are entire communities dedicated to judging other Steampunks based solely on their goggles. A Steampunk without goggles is like Samson without his hair, or a duck without a beak—totally powerless. As I'm sure you also know, the right pair of goggles can instantly render any outfit Steampunk, no matter what it looks like.
For anyone using open source information to conduct an investigation, a balance between powerful tools and privacy controls are a must. Buscador is a virtual machine packed full of useful OSINT tools and streamlined for online research. This program can easily be set up in VirtualBox, and once that's done, we'll walk you through some of the most useful tools included in it.
In our first part on software-defined radio and signals intelligence, we learned how to set up a radio listening station to find and decode hidden radio signals — just like the hackers who triggered the emergency siren system in Dallas, Texas, probably did. Now that we can hear in the radio spectrum, it's time to explore the possibilities of broadcasting in a radio-connected world.
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...
The oven is arguably our most essential kitchen appliance (right alongside the fridge, freezer, and yes, even the microwave). But even though we've been using them for a few millennia, many of us know so little about our ovens that our cooking or baking can feel like a roll of the dice sometimes.
Since its introduction on the iPhone 5S, Touch ID has made unlocking Home button iPhones quick and secure. The second-generation iPhone SE brought back the beloved feature in 2020 but didn't take any steps to improve on the technology. So if you're rocking Touch ID and having trouble getting it to read your fingerprints, there are some things you can do to fix it.

Your attic is the most critical area of your house to be adequately insulated in order to keep you toasty warm in winter and cool as a cucumber in the summer. Since heat rises, a poorly insulated attic allows valuable heat from the living space of your house to escape during the winter. During the summer, heat trapped in your attic can reduce your ability to keep your house cool. In colder, Northern climates, an R-value of 49 is recommended for adequate attic insulation. In warmer climates, a...
Prepare all the materials and tools needed for the process. Prepare a circuit tester, an electrical tape, a flathead screwdriver, a pair of scissors, and an electric sealers kit. Then, make sure that you turn off the power at the main circuit box. Place a piece of electrical tape over the circuit breaker that goes to the circuit that you are going to work on. Unscrew the screws that are holding the plate cover of the outlets to the wall. Test the outlet using the circuit tester to make sure t...

Feel that chilly draft coming through your doors and windows? It might not be as difficult or costly to solve as you might think!
Have a few light bulbs and a blowtorch? Then join the folks over at Harvard in a cool science experiment on the conductivity of glass. As you well know, glass is an insulator with low conductivity and high resistivity. In the video below, they flip the switch, demonstrating how heating the glass fuse enclosure from an incandescent light bulb can create a conductive material that completes the series circuit and lights the second light bulb. In the video, the two light sockets are wired in ser...
The Leidenfrost Effect: “a phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid’s boiling point, produces an insulating vapor layer which keeps that liquid from boiling rapidly”. It looks pretty spectacular captured at 3000 frames-per-second (almost as spectacular as when the same principle is applied to the human hand). Previously, Hand Fully Submerged in Liquid Nitrogen (OUCH... right?)
If you ever find yourself in the unfortunate predicament of being stranded outdoors in the snow, don't eat snow off the ground. Eating solid snow will sap your body of precious internal heat (since the heat will be used to melt the consumed ice), so it is best to melt the snow completely before drinking to stay hydrated.
Paper shredder not working like it used to? Soak several pieces of paper in baby oil and run them through the shredder, which will help lubricate the blades and make them run smoothly for future shredding purposes.
In this article, I'll show you how to built a Wireless Transfer of Energy Transmitter. Simply put, this device will send electricity to a florescent light bulb and light it up, from up to three feet. The idea originally (at least, prominently) came from Nikola Tesla (read more about this amazing inventor here), who used his Tesla coils to transfer wireless energy to light bulbs in demonstrations (photo below). However, the circuit described in this article consists of a flyback transformer, n...
Natural processes often create objects that have a fractal quality. Fractal branching patterns occur in plants, blood vessel networks, rivers, fault lines, and in several electrical phenomena. Many of these processes take lifetimes, or even occur on geological timescales. But this is not the case for electrical phenomena. They often occur near instantaneously. One example would be the branching patterns that sometimes occur in lightning.

A GFCI outlet (which stands for ground fault circuit interrupter) is a receptacle with its own built-in circuit breaker. It is intended to protect you from electric shock and your wiring and breaker panel from being “shorted out”.
Versatility and convenience - two of the greatest watchwords for a comfortable home. Fortunately, installing a 3-say switch can add versatility and convenience to your home's lighting system.
To sound proof a room you have many different options. If you don't have your dry wall up because you don't have your studio set up, put insulation right inside the wall before you put in the dry wall. It is important to sound proof your room because you don't want your neighbors to call the police and you don't want there to be echoes and feedback on your sound. You want your music to be crisp and high quality. The best insulation is fiberglass insulation. If you already have your wall up, y...
No matter how hot it gets in your home this summer, you can bet that it’s even hotter in your attic. All that heat in your attic gets transferred to the ceiling below, which will in turn heat the interior of your house.
Have you ever felt cold in your older home, even with the heat cranked? Ever feel drafts that seem to come from nowhere? And conversely, in the summer, is your home an oven? Many older houses are improperly insulated, if there is any insulation at all. This can have a large impact on your heating and cooling bills. Loose-fill insulation can be blown into your walls and attic to help increase the efficiency of your house, significantly decreasing your heating and cooling expenses.
Installing recessed lighting into your kitchen or living room creates an immediate update to the look of your home! Recessed lighting is very low-key, makes a subtle statement, and yet is elegantly modern. If you are looking for an update to your home's lighting, think "recessed."

The Telegraph reports that a team of researchers lead by Dr. Sang-Woo Kim of the Institute of Nanotechnology at Sungkyunkwan University in Seoul have developed a method for converting the energy from sound into electricity. They've applied the research to the charging of mobile phones, and while you don't have to yell with all the emotion and fear exhibited above by Drew Barrymore in Scream, it sounds like the more energy the better. Dr. Sang-Woo Kim says:
If you're like me, you have a secret dream of living in a house completely covered wall-to-wall and carpet-to-carpet in bubble wrap. Until you have enough of that pliable transparent plastic with air-filled bubbles, there are some truly practical things you can do with the little you do have—besides packing fragile objects.
A flashlight is one of those things you rarely need, but hardly ever have when you do. The normal-sized ones are unwieldy to carry around, and the small ones that you keep in a purse or car are easy to lose.
Remember the Power Pwn, the clever little hacking tool disguised as a power strip? It's great in theory, but with a $1,295 price tag, it definitely doesn't fit into most people's budgets.
Light-weight, tiny, and easily doable, Mark Jurey's penny stove instructional demonstrates how to make a sleekly simple (and cheap) camping stove.
In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits. However, they also look amazing in the dark (check out the photos below, purple plasma is amazing!). And if all else fails, they make a cool nightlight. If you've ever been around a Tesla coil, cathode ray tube TV or sometimes even on a trampoline, you've probably noticed that smell; the smell of "sta...
