Whenever we make a homemade circuit, we use what are called through-hole components. Any components with long metal leads is a through-hole component. They are great for soldering to, but it's tough to fit enough through-hole resistors and capacitors into a smartphone. To get those last microns, we have surface-mount components for SMDs (surface-mount devices). These are all of those teeny, tiny things you see when you crack open your digital camera or laptop case.
If you're like me, you were always jealous of the kids with rich parents who got to ride around in their own Power Wheels cars. Now that I am tall enough to sell my body and time, I find myself attaining childhood dreams like buying my own Power Wheels car. I would not have chosen the Barbie Jeep given the choice, but 40 bucks on Craigslist is an amazing deal.
Fans of Doctor Who know that the sonic screwdriver is the ultimate tool. It can unlock doors, turn on lights, detect life forms, solder wires, and sabotage weapons.
Computer viruses are terrifying. They are undetectable, dangerous, and operate constantly right under your nose. For the average computer user, there are only a few repair options. You could buy expensive antivirus software that causes more problems than it fixes, you can wipe your hard drive clean and lose all of your important data, or if all else fails—just switch to Linux.
In this article, I'll show you how to create a simple yet effective way of scaring off intruders. Of course, there are methods around this approach, but it's great for office pranks and general fun. The project requires a little background knowledge in electronics and circuitry, like reading schematics and using a soldering iron.
Science-fiction writer Jules Verne predicted many scientific breakthroughs, including the moon landing, tasers, and nuclear submarines. In his 1874 book The Mysterious Island, Verne writes:
The agents of empire do not always arrive with warning. When you are besieged, surrounded, and infiltrated, imagination is often your best weapon against the oppressors. If all you have at hand is some duct tape and a disposable camera, fear not, you have the makings of a powerful taser!
I'm back with the third part to my laser weapon series (see part one and two), and I'll be explaining the function, application, and potential of semiconductor lasers, aka laser diodes.
Grab your thinking caps and get your hack on. Null Byte is officially seeking contributors on a weekly basis who are willing to take the time to educate the Null Byte community on anything, from hardware hacks to life hacks. Contributors that write tutorials will be featured on the Null Byte blog, as well as the front page of WonderHowTo (providing it's up to par, of course).
With the purchase of my latest computer, installing Linux turned into a nightmare from Hell. The graphics drivers are probably the biggest issue that anyone with a newer computer will run into when installing Linux. AMD and NVIDIA are the dominant ones on the market, both of which have awful support.
Apple's AirPods Pro offer three different audio modes for your convenience: "Transparency," which pumps in sound around you,"Noise Cancellation," which actively blocks out surrounding sounds, and "Off," which uses neither mode. Off saves battery, and does a decent job at passively cancelling noise on its own, but you can't seem to be able to use it with the AirPods Pro stem. Here's how.

My name is Noah Hornberger. I'm a former Pixar artist (Wall-E, 2008) and Professor of Animation (DePaul University, Chicago), and I have recently invented a motion-activated musical toy called the Dub Cadet. One Substance TV blogger has called my light-up sphere that transforms motion into music, "Daft Punk [the electronic music duo] meets Simon [the handheld toy] in a ball."
Since its inception, Google+ users have been a loud, vocal bunch, and they've made their displeasure known about many issues, especially on the lack of support for pseudonyms, Google Apps, and brand pages. It's been especially galling for many Google loyalists, who found their Google+ profiles suspended, when they ended up violating the Google+ "common name" policy.
Electronic Arts is the biggest game publisher in the world, and have been for years. And yet, their only successful internally developed games nowadays are the EA Sports mega-franchises like Madden. Most of their success has stemmed from their ability to buy other companies on their way up, squeeze the creativity out of them, and then sell them to someone else or just let them go. This week they made their largest acquisition ever when they purchased PopCap Games for $750 million upfront—as m...
Focusing has always been a problem with photographers, and even with today's digital cameras it's not easy. The most obvious problem is trying to accurately focus on the subject before exposure. Next, you have to choose the correct aperture size in relation to the depth of field, and make sure you're using the correct exposure. Then there's lens aberrations, where a certain ray of light does not converge to a single focal point in the desired image, resulting in some light leaking away from t...

Be honest about your pet's ability to travel. If your pet is very young or old, or is ill, pregnant, or recovering from surgery, it may be better for all concerned to look into a pet sitter or kennel rather than take a chance on injuring your pet by taking it with you. If you are in doubt, ask your veterinarian. If your pet has not traveled before, try a short overnight or weekend trip first.
Musical boxes are best known for their kitschy designs and somewhat trivial renditions of musical masterpieces. They tend to frequent the dresser of young girls or elderly woman hanging on to their youth, and for the most part, they remain cutesy and harmless, but when featured in movies like The Silence of the Lambs and Black Swan, they become downright creepy.
I love books. I've loved books before I could even read them. I remember spending any free moments poring over the pictures, trying to pick out the words. I can recall the first triumphant moments when words began to make sense to me. I grew up in a house filled with books and with parents who read me The Hobbit, Little House in the Big Woods, The Chronicles of Narnia and so many others. I brought stacks home from the library, browsed through my dad's office shelves, used up the batteries in ...
We've all heard of the power that red wine holds. It can help lower risks of heart disease, boost your brain power, and can even recharge your car battery. But last year, a group of Japanese physicists made headlines when they announced that they could induce superconductivity by soaking metals in red wine. But why red wine?
The biggest struggle with flashing DVD drives on Xbox 360s has been the price tag of the probe to extract keys on some drives. The probe and kit is required to extract the DVD key, which is needed to perform a drive repair, flash, or backup of any kind. Who wants to pay big bucks for the "pro" kit and then get added to a huge waiting list behind a million other people looking to buy the same product? We can hack the same thing together at home!
In this week's Phone Snap Challenge, we would like you to experiment with lighting and mood setting to create a silhouette. A silhouetted photograph contains a subject that is defined with an outline, appearing dark against a bright background. The subject generally appears dark, without any detail, while the background is bright and more exposed. Silhouettes in photographs appear to be simple, yet they can convey a sense of drama and emotion. Before you get started, check out this guide on h...
Other than keeping your popsicles and frozen veggies frosty, who would have thought that your everyday freezer had so many uses? Just like your dishwasher can be used for many non-cookware items, the freezer can be used in a variety of useful ways that don't involve perishable food.

A few months ago, we showed you a pretty awesome light painting project that visually captured invisible Wi-Fi signals around town using a Wi-Fi detecting rod filled with 80 LEDs. With some long exposure photography, the results were pretty amazing. This project was inspired by those crazy Norwegians, but this build lets you do something even more amazing—capture pictures of colorful written text and drawn images, frozen in midair.

The Kinect is sure to swarm the homes of Xbox 360 gamers this holiday season. Even though some of us are amazed at the hands-free gaming capabilities it offers, others feel it to be frustratingly limited. Adafruit Industries is one of them.
Born in 1975, the world's first digital camera used a standard cassette tape to record images, rather than today's standard data cards.
