There's no shortage of uses for steel wool, but the majority of them tend to be on the pyromaniacal side, like DIY fireworks. This trick by Mike Mikkelson is no different—it uses a homemade reusable "wool cage" to create a spinning vortex of light, like in the photo below. You can do this with just a piece of steel wool on a cable, but Michael wanted something he could easily reuse no matter how many shots he took, so he built a small cage to house the steel wool out of chicken wire, a small ...
When it comes to the quality of a photo, lighting can make or break it. Too much light, and your subject looks washed out. Too little, and you can't even tell what your subject is.
You can use Twitter to print Instagram photos, track news and weather events, or even remotely shut down your computer, and if you're familiar with IFTTT, there's no shortage of ways your account can help automate your life.
Greeting cards. Everyone hates buying them, they're way overpriced, and the majority of them go right in the trash after they're opened. So why do we still buy them?
You can add Bluetooth capability to an old stereo, a retro mouse, or even your car's cassette deck. If you can think of a device, someone has probably found a way to control it with Bluetooth.
There are plenty of ways to mount your camera on your bike, but there's not much you can do about uneven surfaces on the road that cause your videos to end up looking shaky. If you're on a motorcycle, it's even worse because turns force you to lean, which makes your video tilt.
Most of us have traded our desktop systems for laptops, tablets, and mobile devices, meaning there's a lot of outdated hardware sitting in attics. Want to give your old computer a new purpose? Matthew Chappee turned his iMac G4 into an HDTV using the guide by Dremel Junkie. One thing to note before you take on this project yourself is that if you want to use it to watch cable, you'll need a converter box to get around the MPAA's HDCP restriction. But, a converter box is considerably less expe...
At the most recent Apple event, the company announced its new Fusion Drive, a hybrid hard drive designed to increase performance and speed by combining traditional and flash storage. It's composed of a small solid-state disk and a larger spinning hard disk drive, and files and applications are moved back and forth between the two based on how often you use them. A chunk of memory is reserved for whatever task you're currently doing, which means that multitasking doesn't slow down your compute...
For over three years, Facebook users have been able to clog up their Facebook chats with little pictures of smiley faces and red hearts, but now it has finally gone a step further...
Harnessing the power of the sun is something that Captain Planet made cool before it was the go-to for renewable energy. Solar-powered energy is quick and cheap, and can make for some really cool DIY projects. And for those of you wondering what you should do with your old satellite, look no further. Aaron from Sharealikelicence offers up a way to create a DIY outdoor satellite cooker. He started with an old Ku Band dish and covered it with aluminum tape, for better reflection of the sunlight...
Portal, the popular game from Valve, has been critically acclaimed since its release in 2007. Its unique gameplay and humorous storyline is the reason for its popularity amongst nerds everywhere. This has also spawned a large community in cosplay and prop design. The most popular aspect of the game has to be the awesome portal gun. The gun creates companion portals on almost any surface that allow the player to jump form place to place with ease and also allows you to move heavy objects with ...
The newest update of the Firefox web browser was released yesterday, and whether you were upgraded automatically or manually, Mozilla is advising that you downgrade to Firefox 15.0.1 as soon as possible. Firefox 16 is Mozilla's latest release, and is apparently extremely susceptible to malicious sites hacking their users complete browsing history.
Michael Faraday was awesome. He discovered electromagnetic induction, diamagnetism and electrolysis, and he invented the Bunsen burner (before it was the Bunsen burner). Because of his work, we can make suits that can withstand 1,000,000 volts of electricity and cases to protect our gadgets from nuclear attacks.
Earlier this week, we learned that you can get people to put more money in a tip jar simply by drawing eyes on it. But what if you want to keep them away from something? Eyes can do that, too, especially when they're Putin's.
An isomorphic (or self-transposing) keyboard is "a musical device where a grid of notes is displayed to the user and the interval change between notes in constant for any given direction." For those of you who didn't grow up playing the piano like I did, that basically means that it lets you move between keys easily without having to learn new patterns because the keys are laid out so that a chord is the same pattern in every musical key.
Want to know when you have a visitor, even if you're not home? You could always set up a security system and live-stream it with your iPhone. But if you don't have a spare iPhone, or just don't want to go to the trouble, this simple hack will add text message alerts to your doorbell so that it lets you know when someone's there.
To say that I am disappointed with the new Maps application in iOS 6 is an understatement. And it seems like the rest of the world is with me, so I needed to find a solution—and quick. Installing the Google Maps web application is a nice quick-fix, but those looking for a beefier navigation solution should check out one of these free map apps.
Want to take advantage of your neighbor's super fast Wi-Fi connection? If they're smart, they probably have it password protected (otherwise you wouldn't be reading this, would you?). But if you have an Android phone, you can get back at them for always parking in your spot and slamming the door when they get home at 2 a.m.—by stealing...er, borrowing, their connection.
Whether you want to use it to keep your guests safe or just to see who's the most drunk, it's always fun to have your own breathalyzer at a party. We've seen DIY breathalyzers before, like this one by Craig Smith, but how about an Arduino breathalyzer?
Most of us have given up our big, bulky stereos in favor of smaller, sleeker models, but how many of us actually get rid of the old ones? If you don't like the idea of throwing out or giving away electronics you spent good money on, you can always upgrade them instead!
So you've made a somersaulting robot, one that delivers your beer, and even a robot you can ride, but you want to try out something really different. Why not add a steam engine?
One of the most played-up features of Windows 8 is that it's so much faster than previous versions. So fast, in fact, that Microsoft had to change the way that users access the BIOS because 200 milliseconds just isn't enough time to hit the right key. It may take some getting used to, but it's probably a welcome change for most people, considering that the "right" key is different depending on what type of computer you're running the OS on.
There's a lot of firsts that President Barack Obama can claim, like being the first POTUS from Hawaii, the first to publicly support same-sex marriage, and of course, the first African American to hold office. One of his coolest firsts, though, is that he's the first American president to ever brew his own beer in the White House. And thanks to a Redditor who filed a Freedom of Information Act request, two recipes have been released so that home brewers everywhere can give them a try.
You've probably seen the classic fruit battery science experiment a thousand times, but I doubt you've ever seen it turned into an art project! Photographer Caleb Charland uses everyday objects like apples, coins and vinegar to create makeshift batteries, then takes these gorgeous long exposure photos. For the apple tree photo, Charland got about 5 volts for every 10 apples, so he had to wire 300 apples to power the lamp for several hours. He used a zinc-coated galvanized nail and copper wire...
If you've ever been on your way to a party and felt that your outfit just wasn't flashy enough, engineering student 'Rambo' has got just the thing for you. His homemade LED suit lights up and dances to the beat of the music, and can even be controlled via Bluetooth.
Shooting a photo or video in a car can be rather difficult without a proper mount, and if you want to secure your camera outside the car, it can be just plain expensive. Luckily, there are tons of DIY camera mounts for both inside and outside your vehicle, and most of them are pretty cheap to make. Here are some of the best.
Hate answering the door, but don't trust your friends with a set of keys? This RFID front door lock made by Steve Pomeroy will solve all your party-hosting problems. It reads the RFID tags in his friends' public transit cards and decides who's allowed in based on "groups" that Steve defines. And I have to say, it's also rather stylish. It's controlled by an Arduino serial console and a custom Android app to add and remove cards. The reader can store 50 or 100 tags at a time and allows 7 diffe...
One of the most annoying things about summer is mowing the lawn. Depending on how big your yard is, it can mean spending hours out in the hot sun while you could be doing something a lot more fun like watching the Olympics or making giant soap bubbles. Reclaim your summer with this remote control lawn mower that does all the hard work for you.
Want to build your own life-sized, working replica of WALL-E? Be prepared to take on a second job! Mike Senna spent two years perfecting his own version, working 25 hours a week and totaling somewhere around 3,800 hours for the whole project. He had no blueprints to go by, so he spent a lot of time watching the movie over and over to get everything just right. The video below shows some of the construction; skip to about the one minute mark to see WALL-E in action.
AdSense. It's a beautiful thing, isn't it? Google AdSense is something every website owner or blogger should use… it's what every blog needs… if you plan on making any money and surviving. So, how much traffic do you need to actually start making money via AdSense? This video will try and answer that question for you. You must have targeted traffic to drive your blog.
StumbleUpon is one of the biggest ways to draw attention to a blog, website, or webpage. If you're not using StumbleUpon, you're doing something wrong. It's just like Digg. If you take action now, you can start reaping the benefits of StumbleUpon traffic to your blog. By using StumbleUpon advertisements also works, too. There are many tricks to use for increasing web traffic, and this is just one way.
If you thought the news coming from China about the coronavirus might not affect your daily life in Europe and in the Americas, think again.
Cross-site scripting is one of the most common vulnerabilities found on the web today, with repercussions of this type of flaw ranging from harmless defacement to sensitive data exposure. Probing for XSS can be tedious and time-consuming for an attacker, but luckily there are tools available to make things a little easier, including Burp Suite, Wfuzz, and XSStrike.
Apple's dedication to iPhone security is one of the company's biggest selling points. It's no surprise then that iOS 12 offers users a simple yet powerful way to make, save, and auto-fill strong passwords to your iCloud Keychain when creating accounts in both Safari and in apps. The best part? You hardly need to do a thing.
Between Renault Truck's testing of the HoloLens in factories and BMW promoting its newest model through Snapchat, the auto industry is hot for augmented reality to improve internal operations and engage consumers.
We all know the internet isn't exactly a safe place. While plenty of its users are innocent and kind, you won't last long unless you treat every new screen name like a criminal (we're all this cynical while surfing the web, right?). Well, that cynicism is proven correct today, a post on Medium uncovered a group of scammers on the iOS App Store that are costing victims up to $400 a month.
Running diagnostics on your Android phone can be a very tedious process. More often than not, you need to key in dialer codes to see if your device's hardware is functioning properly, though you can also download apps — but these are often hard to understand for a layperson. When a smaller component like a proximity sensor fails, you're often left with no other choice but to take it to a professional.
Intel, the company which is mostly known for creating computer processors, once again showed off their Project Alloy "merged reality" experience, this time during their CES 2017 press conference. Intel's Chief Executive Officer, Brian Krzanich, stated that they will be "productizing" this tech with their partners in the fourth quarter of 2017.
WordPress did not become what is arguably the most popular blogging and CMS platform on the planet because it was difficult to use. Rather, its user-friendly and rich feature set led to it finding a home on somewhere north of 70 million websites—and that's just counting blogs hosted on WordPress.com.
