In college, I enjoyed eating, sleeping and making my roommate's life a living hell. My most satisfying prank involved 500 red cups stapled together, filled with water, and strewn across his bedroom floor. He was not happy. To clean up, he had to unstaple each cup, carry it to the bathroom, and dump the water. He was furious, but I was okay with sacrificing our friendship in exchange for a fantastic story that I'll probably tell my grandkids one day. If you're not as cruel as me, there are oth...
What can you do with a hair dryer besides dry your hair? Lots. You can remove stickers from clothing, clean up crayon marks, and mold your plastic eyeglasses for a better fit. But how about something a little more fun? Well, you can levitate things. Ping pong balls, to be exact.
You can buy special utensils to do just about anything these days, and separating eggs is no exception. If you don't have (or want to buy) a fancy tool to do it, the classic method is simple—just crack the egg and transfer the yolk back and forth between the two halves. But even though egg separators are pretty cheap and using the shell (or just your fingers) isn't hard to do, neither is as fun as this trick by YouTuber jifenzhongDIY.
With gas prices constantly digging into your wallet, biking will always be a cheap and easy alternative for getting around—and it's a perfect way to get in a little exercise. But with the fall season about a week away, it is going to start getting dark a lot earlier and that ride home might be a little more dangerous. So to save yourself an unexpected trip to the ER, take a little time to make your bicycle impossible to overlook.
It can get pretty chaotic when you're gaming. When you're playing a fast-paced game like Black Ops, frustration, urgency, and confusion will lead to a sudden loss of control, i.e. a panic attack. There's an enemy at your six and you try to spin around, but it's too late—and that sudden rush of adrenaline will tear your controller to shreds. It's a step beyond mere button-mashing, because it's not really intentional—you just put a little more force on that thumbstick than needed. And now you'r...
A few weeks ago, we saw a simple 128 inch DIY Projector Screen that looked like a pro built it—and it only cost $200. But this one is even cheaper, and looks just as good. It's also simpler because it's painted right onto the wall. In the video below, How To Lou shows us how to make it with just some white or silverscreen paint, a few pieces of casement molding, and some black velvet for the trim.
So you've made a somersaulting robot, one that delivers your beer, and even a robot you can ride, but you want to try out something really different. Why not add a steam engine?
A tachometer, or RPM counter, is a device that measures the speed of something that's rotating. In a car with a manual transmission, the tachometer can be helpful in determining when to release the clutch and how much gas to give when you're taking off. This DIY Arduino Tachometer by Chris on PyroElectro uses an infrared transmitter and receiver break-beam pair to measure the RPM of a computer fan. When the fan blade passes between the transmitter and receiver, the IR beam counts the interrup...
Christopher Nolan's Batman trilogy has been one of the most successful film series of all time, so it comes as no surprise that everyone wants their own real-life versions of the Dark Knight's gadgets and vehicles.
Looking to transmit some super-secret audio communications to your other spy buddies? A laser is the perfect tool for getting your sounds heard from a small distance—without anyone intercepting them— even if it's just a cover of your favorite pop song. A laser audio transmitter uses light rather than radio waves to transmit sound. This is a much more secure way to send audio communications because the laser is a focused beam of light, whereas radio waves are not controlled, so they can be pic...

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.

Believe it or not, that's what whipped cream looks like when viewed through a spectrometer. You can do this w...
Looking for a way to make your bike stand out? You could light it up with LED rim lights or turn signals.

To actually make these wooden handlebars, you will need some woodworking tools, not to mention some actual woodworking skill, or at least the tools and some knowledge on bending and forming wood. In his video below, David shows exac...
You can do a lot more with playing cards than you'd think, like turn them into gift boxes, fling them like throwing stars, and make them levitate or disappear. You can even make them recharge your batteries. Instructables user Shawn Frayne was sick of having a bunch of dead batteries lying around, so he developed a cheap and easy way to always have a charged one within arm's reach by turning a normal playing card into a super simple solar-powered battery charger for rechargeable AA and AAA ba...
Back in 2008, media artist Kyle McDonald created a 3D interface that could track movement, which he turned into a virtual Tic-tac-toe game.
Want an electric car without the price tag? You could always build your own, or maybe just hack your old gas guzzler into an eco-friendly electric machine... This weekend at Defcon, security consultant David Brown showed off his "Voltswagon" project, a 1974 Beetle named Shocky that he converted to electric for only $6,000. He removed the old combustion engine, radiator, and a few other unneeded parts to make it lighter. Then he loaded it with batteries front and back, ten Interstate DC-29, 12...

Unless you're living in some weird parallel universe where plug-in light bulbs are the norm for household lighting, chances are you've had to unscrew a light bulb every now and then.
Before, eReaders were only used to read eBooks. Not anymore. As tablet computers become more and more advanced, eReaders like Amazon's Kindle, Sony's Reader and Barnes & Noble's Nook are forced to expand their capabilities beyond the basic bibliophilic needs. And the first to make significant headway is B&N's Nook Color.
Christmas decorations aren't cheap. From outdoor lighting to fir trees, decorating for the holidays can break the bank. That's where ingenuity comes into play, like hacking battery-operated Christmas lights, modifying lighting patterns and building Christmas tree ornaments from LEGOs. But there's even a simpler solution to cheaper Christmas decorations— origami.
So, you can't decide— movie on your iPhone or web-surfing on your iPad— why not do both?

Back in the 1940, a lot of people called women Dames. It was okay then. You might not get away with it now. One thing you can't ever called a woman is an imbecile, with or without the French accent. But you can earn the Femme Imbecile trophy in the A Slip of the Tongue DLC for L.A. Noire on PS3.
