A while back, I wrote review of my favorite hacking movies of all time. Two of my key criteria were; (1) how realistic was the hacking, and (2) are the hackers portrayed as the "good guys." This past winter, a new hacker movie was released, appropriately named Blackhat starring Chris Hemsworth (from Thor fame) as a blackhat hacker who is released from prison to stop a notorious and destructive hacker that only he can stop. Although the movie did very poorly at the box office, I thought it was...
In a previous article, I demonstrated an Arc Welder made using parts from old microwave ovens. Video: .
For a car to operate normally, it must have some basic care and maintenance. In these free automotive repair videos, learn how to maintain your engine cooling system.

With the new iPhones coming out, many see the current mobile market as just another epic battle between Samsung and Apple. But let's not forget there are many other phones that run Android. And when you start to sift through the specs, one stands out as a competitive alternative to the iPhone XR, the LG G7 ThinQ.
The LG G7 ThinQ will likely be lambasted for its notch and awkward name, but one thing they seem to have gotten right is the new display. The G7 ThinQ will give many a first look at a new type of panel with lots of promise. While it was previously limited to TVs, from what we know, it should really shine on a smaller screen.
Samsung hopes to make a splash with the new Galaxy Note 9 to make up for the underwhelming sales of its signature Galaxy S9 series. This flagship is a radical departure from its predecessors — it's now optimized for gaming and paired with the most advanced S Pen stylus to date. Here's everything you need to know.
Apple's iPhone 8 and iPhone X announcement went about exactly as the rumors predicted. Really, there was only one surprise — the fact that all of the new models will support the Qi wireless charging standard.
I had the opportunity to speak with the COO of Osterhout Design Group, Pete Jameson, shortly before the announcement of the company's R-8 and R-9 smartglasses models at CES in January. And while I sadly could not make it to CES to test the smart specs out right away, ODG invited me to do just that while I was in San Francisco for the Game Developers Conference.
Video chatting has become an important factor in the overall smartphone experience. Even just a few years ago, 37% of teens were making video calls on a regular basis, and that number has surely grown. 85% of households with infants have used video chat apps to call relatives in other cities, and it's been shown that toddlers can create bonds and learn from visual cues in video calls.
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.
Mobile gaming still isn't on par with video game consoles or PCs, but we've come a long way from Snake. Modern games running on the latest smartphones boast downright impressive graphics—even more so when you consider how compact the system has to be in order to fit in people's pockets.
Once upon a time in America, there was coffee and there was decaf. That's it. No capuccinos. No espressos. And certainly no Starbucks. Coffee was just coffee, something that you bought at a gas station or donut shop. If you made it at home, it was either in a metal pot or instant coffee.
The ability to make a meal for yourself used to be one of those life skills you had to learn or otherwise you would starve, but the rise of convenience foods, takeout, and other aspects of modern living have made it entirely possible to be a grown person and not know what to do in the kitchen.
Hard-boiled (also known as hard-cooked) eggs are notoriously easy to mess up. We've all ended up with tough, rubbery egg whites and overcooked yolks that have that unappetizing gray-green ring around the edge. An ideal hard-cooked egg has a firm yet tender white, while the yolk is creamy and well-done without being mealy.
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?
There is a whole world of smartphone accessories out there, some of which are more quirky than others and don't get the recognition they deserve. But these sometimes strange, sometimes embarrassing products can really make life easier on your iPhone or Android phone.
Android comprises an entire ecosystem of apps, games, functions, and features, so it would only make sense that it has its own lexicon. Words, phrases, and acronyms that didn't exist ten years ago are now used in an off-the-cuff style by developers and support technicians across the web.

His name is Don Pettit, but I like to call him Space MacGyver. He's well known for his paper clip fixes and ingenious coffee invention in zero gravity, and we've all seen the NASA astronaut in his Saturday Morning Science videos during his first stay on the International Space Station. And now he's back on the ISS with a brand new physics-related show... Science Off the Sphere.

Microsoft has had a pretty bad wrap with their Xbox 360 gaming console. Right from the start, the console has suffered a multitude of different hardware failures and design flaws. These problems cause the parts to get too hot and become faulty. I'm sure everyone who's had an Xbox 360 has gotten at least one Red Ring of Death or E74 error.

Piezoelectric Energy In this article, I'll show you how to make a small, wallet-sized device that generates electricity from kinetic energy. The concept is simple: Piezoelectricity is the charge that is produced when certain solid materials (commonly ceramic and crystal) in response to mechanical stress. Piezoelectrics have many applications; in speakers, actuators, sensors, even fuses. For more information, click here.

In this article, I'll show you how to make a simple touch-triggered switch. This is very useful for various electronic projects, from a simple bedside light to a flat panel touch keyboard. The circuit can vary in switching power depending on the transistors you use. For example, if you're looking into creating a 120V light that turns on when touched, you'd need two powerful transistors and an isolation relay. However, a simple flashlight that turns on when touched would only take a couple of ...
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.
In this article, I'll show you how to make a high-powered, long-range, air-powered rocket gun. This launcher is based on a sprinkler valve, a modified propane tank, and a few other components. Though not hard to make, this device is VERY dangerous! The rocket can seriously harm, if not kill any living thing it's shot at. Here's a video of it in action, quite an accurate shot by my friend Chris... Parts
First Things First Before you can begin to work on a damaged panel, you must determine what type of material that you are working on. For instance, the panel may be mild steel, high strength steel, aluminum, plastic, sheet molded compound, or a number of other types of material.
