Your favorite device is running low on juice and needs a couple new AA batteries—and with a quickness. You run to the store and grab the first pack of AAs you see. But should you? There's tons of options available, so which make and model gives you the most power per dollar?
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?

If you didn't think you could make a high speed photography trigger or hack together some creepy googly eyeballs for Halloween, then you've got another think coming, because learning how to use Arduino just got easier thanks to Jody Culkin and her wonderful comic book introduction to the Arduino platform (and electronics projects in general).
The use of unmanned aerial vehicles (UAVs) has been widely used by the military for surveillance and reconnaissance missions—even armed combat. But there are other beneficial applications of an unmanned aircraft, such as search and rescue operations, scientific exploration, locating mineral deposits, transporting goods and even filming bikini models. But drone development can be pretty pricey, unless you just happen to have a 3D printer...
Kudos to student Tim Wheatley, who came up with this incredibly nifty DIY animation using a bicycle wheel, cardboard cut-outs, and wire to create a magical reinvention of the classic zoetrope, Earth's earliest form of animation (it first surfaced in China around 180 AD!). Simply give it a spin, and the animation comes to life. Inspired to make your own? First, learn the basic principles of the zoetrope here or here. Next, take a little advice from Tim to add the "cyclo" element:
Not in the mood for a sappy ending? Well, strap in because "Emotional Response Cinema Technology" lets your own body physiology control the movie music, the special effects, and even the movie ending. A collaboration between BioControl Systems, Filmtrip, and the Sonic Arts Research Center at Queen's University Belfast, the technology was recently showcased at the SXSW film festival in Austin, TX, where the newly minted horror film Unsound interacted with the audience through wires connected t...
Matt Reed, a web developer at Nashville interactive ad agency Redpepper, built a massive, real life Facebook Like "button" out of Legos, which lights up whenever someone clicks Like on his Facebook page. The programmer loves LEGOs, and draws an affinity between the legendary building blocks and engineering: "[Legos] are great for prototyping physical objects. I don’t manufacture things, but I do click blocks together. Plus, most things I deal with on a daily basis are pixelized. Legos are som...

Now, with the help of Invent Geek, you can make your own DIY Vibrating lock pick for about a tenth of the price of a manufactured kit.
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.
The future of technology promises more and more seamless daily interactions. Pee on your phone, test for STDS. Or perhaps more widely appealing, ditch your wallet for all-in-one easy mobility.
David Adams' Pac Man themed pumpkins are so cute, you're definitely going to want to preserve them as long as you can!
Willow Smith has what it takes to be a star, just like her parents, Will and Jada Smith, and her brother, Jaden Smith. But this Smith, at the tender age of 9, is quickly becoming a pop superstar and preteen trendsetter, thanks to her music video "Whip My Hair".
Think you're a music lover? Then arrange to offer up your remains as the final sacrifice to the Gods of Rock. A UK company called And Vinyly offers music fans an interesting post-death "alternative": have your ashes pressed into a vinyl recording of your favorite song, or opt for a personalized recording of your last will and testament.
Theo Gray of Gray Matter explains the principle behind sending steel up in flames- as long as it's steel wool, of course. The process is beyond simple. Spend 2 bucks and 2 minutes: purchase a steel wool pad, hold in pliers, light with a match. But the question is, why is steel wool flammable, while other forms of metal are not? Explanation below the video. Theo says:
Born in 1975, the world's first digital camera used a standard cassette tape to record images, rather than today's standard data cards.
I've heard blind people have heightened senses, but I never imagined it could translate to such superb soccer footwork. As you watch below, remember this- all players are legally blind except for the goalie.
Gottlieb Daimler's "Revolutionary Riding Car" of 1885 doesn't look like a car (in truth, it would be more analogous to what we recognize today as a motorcycle), but it did mark the very first inkling of the automobile age.
How many gallons of gas does it take to get from Kansas City to New York? Depends on what you're driving. In this custom-modded Indy race car designed by students at the DeLaSalle Education Center? About four.
As sports fanatics, we know how central instant replay is in professional sports. The NFL proved it to any non-believer many years ago. Now the rest of the world is playing catch up. Yes, I am pointing my fingers at the FIFA idiots who run the World Cup. (UK was robbed against Germany). And baseball... Selig should apologize to Armando.
DARPA and Dallas's Southern Methodist University are collaborating on a super high tech camera, capable of scanning eyeballs in a moving crowd.

With an impressive series of viral music videos to their name, it is no surprise that the latest video from indie rockers OK Go is another hit.

The upcoming Shell Eco-Marathon promises to unveil vehicles that will blow current fuel economy standards way out of the water. California Polytechnic State University is one of the most promising contenders, with a vehicle that gets 13 times the 230 mpg General Motors promises the Chevrolet Volt will deliver (plus, the Cal Poly car doesn't even use batteries!).
Chemical engineers at Cornell have created a small device that may one day turn troops into real life spider-men. The device would cradle in the palm of the hand, allowing troops to scale walls. It uses an adhesive inspired by the Floridian leaf beetle, an insect that "can adhere to leaves with power 100 times stronger than its own body weight".
While most smartphones have the ability to receive FM signals via a tuner, mobile carriers prevent users from taking advantage of this hardware — probably in an effort to get their customers to spend more money on data.
Hello y'all! I apologize if this question has been solved somewhere else, but I have looked around on Google, Yahoo, and Null Byte and have not been able to find any working solutions.
It's no secret that we love the Chromecast. From watching movies to playing games to giving presentations, this little $35 dongle definitely packs a punch. But unless you have a strong, solid Wi-Fi connection in the 2.4 GHz range, this little device has been out of reach to you. Well, until now.
A long summer road trip brings opportunity for adventure, but also increases the chances for minor disasters including backseats that smell like stale French fries, getting lost in unfamiliar roads, and getting unexpectedly carsick.
To decrease the possibility of breaking your glass dinner plates while moving into a new home, stack them vertically inside a box like vinyl records instead of horizontally like a stack of pancakes.
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.

The electric air freshener is one of those devices that seems like it could only have one possible function, but can actually be repurposed in a few different ways. If you're looking for a practical use, you can turn it into a bug killer, but it's also perfect for pranks.
For some, Halloween is all about the candy. For others, it's more about causing trouble. There's nothing wrong with a good laugh, but no one wants to be the target of a prank that will entail lots of cleaning later.
