Ever wonder what your brain looks like on video games? Below, Matt Richtel of the New York Times lies in a $3 million M.R.I. scanning tube while playing a simple driving game, as researchers sit by and observe the real-time images inside Richtel's brain.
It took him a year to build and about $30,000 in parts, but Steve Hassenplug has created a truly magnificent robotic chess set, inspired by the magical chessboard in the first Harry Potter movie. Quite a task, but Hassenplug did an incredible job!
How can a small curtain cover a window three to four times its own size? With a motor and a robot brain, that's how!
The race to the driverless finish line just got more challenging as Apple seems to have joined the pack. Friday, the global superpower secured a permit from the California Department of Motor Vehicles that allows them to test autonomous cars in the state.
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.
Bonafide How-It's-Done (not exactly a HowTo) on remote-controlling your car via iPhone and Power Wheels. Brought to you by some crazy Texans, over at Waterloo Labs.
I have personally done this and its tons of fun so I thought I would share it with all you guys. Simply go to the thrift store or garage sale that has power wheels (kids grow out of them all the time) and then take out the battery and motor. Then set up a race going down a steep hill and race each other. Its ok the first time just normally but then add a even steeper hill and the rolls that gift raps come on and its a whole new level of fun.
What causes stress for a teen is a lot of different things. Most of the common ones are: Parents
Jamie Zawinski uses a command line to control his curtains.. ..How cool is that?
If you've ever used a font editing program to create a font, you know that one generally shapes the various forms by arranging points on a screen with a mouse. But what if those points were controlled by something other than fine motor skills? Andy Clymer of high profile type foundry Hoefler & Frere-Jones was interested in exploring alternative methods for how a typeface is developed; hence, "font-face" was born. Font-face employs facial recognition to control the design parameters of a font....
While most people go to great lengths to conceal their emotions, Japanese company Neurowear is offering a product that would reveal states of tension, excitement and relaxation—all by the up-and-down motion of a pair of cartoony cat ears. Necomimi is a "new communication tool that augments human’s body and ability." The device reads your brain waves and communicates your emotions before you even open your mouth:
Scientists have good and bad news for hard-driving people who boast they need only six hours of sleep a night. The good news is a few may be right: Researchers at the University of California-San Francisco have identified a family with a genetic mutation that causes members to require only six hours sleep a night. The bad news? The gene is vanishingly rare in humans, found in less than 3% of people.
Instructable user samsmith17's solution for riding in the dark is a lot snazzier than your typical bicycle light:
"A major hardware update to the masterlock cracking robot. Upgraded the previously non-working latch opening mechanism to be geared down 1:25, allowing it to open the shackle. I also revamped the motor mount to be sturdier, and the base of the unit to hold the lock better and also be easier to mount parts to.
When choosing a security system for the office, Billy Chasen decided to ditch the traditional lock & key barricade for something a little more 21st century. He hacked together a device that uses a web server, servo motor and some parts from Home Depot to enable locking & unlocking via text message. Chasen maintains a list which gives access to green lit office workers, who enter by simply texting "lock" or "unlock"... and voilà, open sesame.
Wish you could make the shift to electric or hybrid, but you can't afford it? If you've got more than a few free weekends on your hands, you may want to consider undertaking Benjamin Nelson's ambitious (to say the very least) car conversion project.

Indianapolis-based motor junkie Paul Stender and his team of vehicle modders called the Indy Boys Inc have created the ultimate anti-fuel economy: a school bus outfitted with a Phantom fighter jet engine, which clocks 367 mph and burns 150 gallons of fuel in just a quarter mile. Stender says:
PopSci breaks down how basic functions of R/C work. Once you've mastered it, the sky is the limit. You can remote control anything. Well, almost anything.
Kitschy kicks your thing? Try these self-lacing sneakers on for size. Inspired by the iconic Nike Air 2015s worn by Michael J. Fox's character in Back to the Future Part II, these shoes utilize an Arduino-powered force sensor and somewhat bulky pair of rear-mounted servo motors to pull themselves tight when offered a human foot. A switch reverses the process. Feeling ambitious? Head over to Instructables for complete instructions on how to build your own pair.
Seems just about anything can be constructed with LEGOs these days. You name it- a printer, an engine, an ATM, guns... even a house!
Well, not just chicks. A couple LEGO dudes, too. (Oh, and a horse). All I can say is, I'm head over heels in love. With a LEGO People operated, felt tip pen printer. B3ta forum member Squirrelfantasy spent about three weeks building his LEGO printer, which uses a felt-tip pen in place of an ink cartridge.
Sean Stiegemeier has captured absolutely beautiful timelapse footage documenting the eruption of the Eyjafjallajökull volcano in Iceland:
You'd think a Hummer couldn't get any more over-the-top (unless you're talking a horse-drawn Hummer or remote-controlled Hummer, of course), but Japanese tuner Calwing’s US division, 213 Motoring has come out with a Hummer boasting a whole extra set of wheels. I'm not quite sure why this is necessary, but nonetheless, Bornrich reports:

The itch chair, designed by Dana Gordon and Alejandro Zamudio Sánchez, is a futuristic chair that scratches the back of the sitter.
The superman exercise can be used to work the lower back (erector spinae muscle). This exercise also works the hamstrings, butt, and shoulders. Some experts maintain that the superman exercise overloads the spine in a potentially unsafe manner. Thus, contralateral supermans are usually preferred. The contralateral superman exercise involves raising only one arm and the opposing leg (e.g. left arm, right leg). With this technique, there is a reduced load on the lumbar spine. The following are ...
The contralateral superman exercise is ideal for working the lower back (erector spinae muscle). This exercise also works the hamstrings, butt, and shoulders. Some experts maintain that traditional supermans overload the spine in a potentially unsafe manner. Thus, contralateral supermans are usually the recommended alternative. With this technique, there is a reduced load on the lumbar spine. The following are instructions for contralateral supermans:
Direct current (DC) by definition flows in one direction. Alternating current (AC), on the other hand, periodically changes direction, or reverses polarity. It is indeed possible for a portion of a circuit that is normally DC to periodically change direction, or reverse polarity like an AC circuit.
There are many ways to make a lightsaber. You can turn a flashlight into a steampunk lightsaber, you can make a lightsaber from junk, and you can make one that looks totally real (if you've got the money and time). Heck, you can even make one in Photoshop. And now you can make one using an infographic! Who doesn't like infographics? This infographic by Herbert Pocket, which may or may not have been inspired by this lightsaber infographic, will show you the quick route to making a Star Wars wo...
I thought lawnmower racing was purely a redneck sport, but apparently not. With the world record speed currently at 80 mph, the UK's Project Runningblade aims to squash it at 100 mph.
The secret hideout - a thing of the past, a childhood luxury, an adult-less adventure. Those were the days. And remember the secret knock? The only way in. You either knew it or you didn't. The only way to keep the kids in and the grown-ups out.
From Jalopnik: The LOLrioKart is outfitted with..."a hundred pounds of Ni-Cad batteries in the lower tray, a crude steering rack up front, pneumatic tires all around and some power-electronics to control a 15 HP Etek pancake motor hooked to a sweet custom differential at the rear all good for a top speed of 35 MPH."
Amateur Chinese inventor, Tao Xiangli, has built his own homemade submarine. Drawing inspiration from the James Bond and Terminator movies, Xiangli's tinkering is quite impressive, considering his education came to a halt at the fifth grade.
