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.

The original NES controller has become one of the most recognizable symbols of the Nintendo gaming culture, thanks to its perfectly rectangular shape and simple button design.

Remember going to the doctor when you were a kid? If the word 'traumatizing' comes to mind, you'll love the RoboDoc by MarkusB, a robotic doctor that makes checkups a little less scary (and a lot more fun) for kids. It all started when Markus took his 14-month-old daughter for a checkup. The finger clip that the doctor used to check her pulse terrified her, so Markus decided to build a heartbeat monitor just for kids that's much more likely to make them laugh than cry.
WonderHowTo has seen its fair share of dragon-related projects, from dragon wings, to dragon kites, to less-complicated origami dragons, but we've yet to see anything quite like this. Radio-control plane builder Richard Hamel built this incredible seven-foot-long, fire-breathing dragon using a JetCat P80 turbine and a 50,000 volt stun gun, with a 2.4-gigahertz touchscreen radio controller to fly it.
A spectrometer is a device that splits light into all of the different colors it's composed of that can't be seen with the naked eye. It does this by using a prism to refract or bend the light. Jeffrey Warren over at Public Labs created a tutorial showing how you can make your own video spectrometer and create spectra like the one pictured below. Any guesses as to what the subject is? Believe it or not, that's what whipped cream looks like when viewed through a spectrometer. You can do this w...
It's been proven over and over that you can make batteries out of fruits and vegetables such as lemons, potatoes, and even apples. Turns out, passion fruit is also acidic enough to power a battery, but Maui Makers member Ryan K decided to take it a step further by adding a laser. Passion fruit, or Lilikoi as it's called in Hawaii, is usually over-abundant in Maui, so Ryan decided to put it to good use. Using anodized bolts, copper pipe, wire, switches, and some LEDs, he built a battery that c...
If you're at all like me, you constantly get frustrated that repeaters only boost redstone signals in one direction. It's annoying!
Security researcher Nadim Kobeissi has discovered that the Windows 8 SmartScreen feature, meant to screen downloads for malicious software, actually reports the data about which applications users are installing to Microsoft. He also says that "the Microsoft server is configured to support SSLv2 which is known to be insecure and susceptible to interception." The two main concerns are the ability of law enforcement to subpoena Microsoft for the information and of hackers to intercept user data...

Riding your bicycle at night is dangerous on busy streets, especially if you've got no bike lights. In most states, it's illegal to ride your bike at night without any lights because drivers on the road won't be able to see you until it's too late. Plus, how is anybody going to notice your sweet ride without a little illumination?
Technology is awesome. You can use your iPad to record music or even turn your tunes into a solar system, but sometimes being plugged in all of the time can leave you nostalgic for simpler times. This new concept by Joelle Aeschlimann brings together the best of both worlds by turning your iPad into an old-fashioned, hand-cranked music box. The artist created three different music boxes, each one with its own unique song and visualization. The music boxes were made using wooden cylinders with...
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.
Dogs make great best friends, but anyone who's had one knows they can be the most high-maintenance friend you've ever had. Bathroom breaks, feeding schedules and walks are only the beginning. Even if you make your dog organic treats and teach it neat tricks, it still needs to play. And after that fifth game of fetch, your arm can get pretty tired.
Choking is scary in any situation, but it's exponentially worse when there's no one around to perform the Heimlich maneuver. Even more so when there aren't any chairs or countertops anywhere. Fortunately, fire medic Jeff Rehman has a great method for saving your own life when things get desperate. Best of all—it requires nothing more than a solid floor.

Since the days of Archytas, rocket propulsion has been the Holy Grail of aeronautics. Thanks to Galileo's inertia, Newton's laws of motion, and the "father of modern rocketry," Goddard, space is not a complete mystery anymore. Rocket-powered aircrafts have evolved from the first liquid fuel rocket in 1926, to the Soviet R-7 which launched Sputnik, to NASA's Saturn V that propelled Apollo 11 to the moon. Today, even billionaire tourists can enjoy space, like Microsoft's Charles Simonyi and Cir...
