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.

Solar panels are an amazing invention. Catching energy from the Sun before it even enters Earth's food chain, photovoltaics are like an all-natural nuclear power plant. Unfortunately, the constituted parts of a solar panel are rare, valuable, and subject to the coercive forces of market competition.
Bikes are a great form of transportation. They use human energy more efficiently than any other machine. You can keep it in your closet or hallway. You can even take it on the train in a pinch. However, this portability is also the bike's biggest draw back. If you own a bike in the city, chances are it will be stolen. Locks barely deter thieves armed with bolt cutters and crowbars. Throw the bike thieves for a loop and make a tilt-sensitive alarm. It will hopefully startle your bike's assaila...
In this article, I'll be covering Triggers and Coils, part two of the series (see part one here). Generally, a simple EMP generator consists of four components; a capacitor, a transformer, a trigger and a coil of copper wire. The transformer component can be varied, but the coil is very important, and must be precisely tuned.

Hi again, Just wanted to share a neat little code that I found way back, when I was presented with a spreadsheet which was locked and asked to ''unlock'' it or do whatever it takes to enable the user to edit it's contents.
This week saw the release of Gears of War 3's most extensive DLC to date: RAAM's Shadow. Having played the first hour or so of the single-player component, I have to say that it is very good. The story serves as a prequel to the first game in the series, taking place right after Emergence Day. While it's a little pricey at 1200 MSP (or $15 in actual money), the amount of content you get in RAAM's Shadow makes up for the initial investment. It's also one of the best Xbox 360-exclusive DLCs out...
Flying orbs. At first, you might think of the Tall Man and his army of flying sentinel spheres, equipped with zombie brains and a mini-arsenal of saw blades, drill bits and shooting lasers. But these flying orbs weren't conceived from the evil mind of a superhuman mortician—they were designed by Fumiyuki Sato, a researcher at the Japanese Defense Ministry's Technical Research and Development Institute—for something other than deadly deeds.
It's best known as a children's toy, but kids aren't the only ones who can appreciate the unique and marvelous properties of Silly Putty. It's an incredibly fun silicone polymer that almost seems like a scientific anomaly, thanks to its viscoelastic non-Newtonian flow. This amazing dilatant fluid can be stretched, torn and mashed back together, as well as bounce and shatter into pieces with a forceful blow.
In recent years, communication has become more intimate with the advent of applications like Skype and FaceTime, but what about the longing for actual physical contact? What if you could feel a loved one's hand, or even exchange a kiss? Impossible, right?
Food is the meeting place of left and right brainers: Culinary arts call for creativity, but is also deeply rooted in the What, Why and How of basic science—baking powder vs. baking soda, the rising of dough, the falling of a cake, etc. Below, two plays on left brain principles—the Möbius strip and the law of gravity—both executed with right brain flair.
Rovio's highly successful Angry Birds game has generated a slew of wannabe Angry Clones and dominated nearly every device and platform known to man—iPhone, Android, PSP, Xbox 360, Windows—and now, for the first time it's available for play directly on the web (for free). It was specifically designed for Google's Chrome OS and their new Chromebook line of laptop computers, but can play on any device in almost any web browser (like Firefox).
Some people might check their activation status of Windows XP by simply right-clicking on the My Computer icon on their desktop, then clicking on Properties. It opens up a new window with General tab showing some basic information about your PC, like system info, registered to, and computer hardware. However, it does not actually tell us complete information about the system, like whether or not your current copy of Windows XP is activated or not. To check the complete details about your Wind...

One of the biggest downsides to having so many gadgets is that you never seem to have enough outlets to power them all. Most of us have a power strip or two to solve this problem, but Instructables user dlewisa wanted something a little nicer looking, so he built this DIY desktop power outlet. For the housing, dlewisa put together a small wooden box using a nail gun and wood glue. He used a sander to round off the corners, then filled in the gaps with wood filler and painted it.

Creating any object you want is as simple as point and click if you have a 3D printer at home. If you don't have one handy, there are a few companies that offer printing services online. But to help services realize your design in extruded plastic, you have to make a 3D computer model for the printing machine. For beginners, the free Google SketchUp application is the best choice of software. Using only a few tool bar buttons and a scroll wheel computer mouse, you can model literally any obje...
It's Monday, time to highlight some of the community submissions posted to the Math Craft corkboard. One of these posts inspired me so much, I think it merits a closer look. Today, I present a "simple" method for making a golden spiral using just a straight edge, a compass, and a template, inspired by RJ Ellicock's golden ratio post.
For more than a decade, Interplay was arguably the best video game publisher in America. Their list of games is a who's-who of the most creative and forward thinking games of the '90s, including everything fromOut of This World to Alone in the Dark to Earthworm Jim to Descent. They've been around since 1983, but have fallen on hard times since 1997, when they became a public company. They were acquired by a French publisher who then went bankrupt. They were forced to close their internal deve...
For Windows laptops and PCs it's easy to install Linux. However for Macs, it's a different story. There are people installing Ubuntu on Macbooks and so far I've noticed that they are using 9.10. I've remastered my own Ubuntu 10.04 complete with playing flash videos and other applications already pre-installed on a DVD. Plus, it can boot on laptops with Nvidia graphic cards. If you'd like to see my workaround for Nvidia check out my article on remastering Ubuntu.
Though it could be argued that Apple's popular and widely used iTunes media player was responsible for the growth and explosion of podcasting, I would argue that iTunes is not the best way to manage and listen to your podcast subscriptions—if you're a iPhone, iPad, or iPod Touch user. Instead, you will find that a $1.99 mobile app called Instacast (iTunes App Store link) is a much better method. Below, a short video introduction to Instacast, plus a written breakdown of its features. Mobile L...
Video games consoles have long wanted to be more than just consoles. Nintendo Japan called the NES the Famicom because they wanted to make it the sole family computer. Obviously that didn't work out, and most efforts to make consoles into all-in-one entertainment systems have had similar fates. Sony has done the best job with the Playstation consoles, probably because they have experience with other types of electronics that most video game companies do not.
