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".
Images of BlackBerry's two upcoming Android phones have surfaced. Reportedly named "Hamburg" and "Rome," keeping with the company's tradition of using cities as code names for its devices, the images come from BlackBerry Central founder Dylan Habkirk (via Times News UK/GSMArena).
Mobile World Congress is just around the corner, and if patterns stay consistent, Samsung will be unveiling their newest member of the Galaxy line, the Galaxy S5.
Staples may be an office staple when it comes to joining sheets of paper together, but they're a pain in the ass if you ask me. They're annoying to take out, you can't shred 'em, and they eventually loosen up. Plus, staplers tend to stop working right when you need them the most.
Enjoy the deliciousness of a peanut butter sandwich without the artificial chemicals that comes in store-bought jars. To make your own peanut butter at home, all you need are pre-roasted peanuts, peanut oil, and a little bit of salt and sugar.
If people are constantly asking you why you look so tired, then maybe it's time to get rid of the puffy dark circles under your eyes.
However much you love your summer barbecue parties, you probably won't be going through your entire bag of charcoal briquettes anytime soon. So, take advantage of your charcoal excess by putting them to good use in other ways!
Have a hard-to-open jar? If it's never been opened, the air pressure inside the jar is making it harder to break the seal. If it's been in the fridge, it's possible that the lid shrunk slightly—just enough to be extremely frustrating.
Broken glass Christmas ornaments? Evergreen wreath falling apart? Before you throw away or donate Christmas decorations you no longer need, see if you can reuse or recycle them for better use year-round or for next year's holiday season.
What are you going to do with all of those Euro coins you still have from that trip to Barcelona with Grandma Margie? Instead of keeping them in a drawer and counting down the number of days until you can afford another trip, try something creative—take on this awesome miniature plane build.
There are so many unpleasant things about flying. You have to wait in line after line, take off your shoes, belt, and jewelry, and somehow make sure your luggage stays intact. And then, once you've made it onto the plane, there are the awful movies that most airlines play—if you even get a movie.
I have an interest in using recycled materials in sculptures, particularly circuit boards and other wasted electronic and mechanical components with which I put together sprawling cities lit with fairy lights. These cityscapes can conjure an image of a parallel society built from what we throw away. Utopian or dystopian, the ‘Electri-Cities’ remain a feast for the eyes and the mind. What makes them particularly intriguing is the population of tiny model railway people—they bring a host of nev...
Hello! This post is about the electrical socket. Imagine that somebody pulled the cable out of the possible protection outlet too fast? The result can be seen on the following photo. What to do next? Step 1: Preparation
Watch this "Grease On Your Hands" video tutorial from the Washington Post to see how to change the engine oil in your car properly.
In Mexico there is a game called Matatena where you have to throw a ball and take some simple objects before the ball fall, who takes more win. In Bowling Matatena you are going to do the following: a Jackass' dude has to put a bowling ball in the begining of a metal rail (bigger than the drawing), then he has to run to the other side and take more matatena's little things before the bowling ball falls over his head, hand or whatever...
Get a Big metal ball (the kind of ball motocycle ride in it in circuses) put some cameras in it and some jackass dudes inside the ball (Chris pontius , Dave England, Preston Lacy, Ehren McGhehey) Next make big styrofoam bowling pins that people can stand on (dudes in pic.)find a big hill and bowl away..
Ingredients 3 tablespoons unsalted butter, cut in 1/4-inch cubes, divided
Leaving scissors wet or forgetting them outside can cause them to rust. Rusty scissors, if you can even open them, will leave brown marks on everything you attempt to cut through. Attempt is the truth—rust dulls the blades of the scissors making it virtually impossible to cut through any type of material, ranging from paper to fabric. But don't toss the scissors in the trash just yet. You can restore rusted scissors to a usable condition provided they are not completely covered and have rust ...
How to... Remove A Very Tight Lid? Use Items You Have Around The House! Step 1Want to remove a very tight lid? Do you have a weak grip or arthritic pain in your hands? Have you already tried tapping the lid with a spoon? Thumping the bottom of the jar with the palm of your hand, and it still won‘t come off? An easy, quick way to remove a very tight lid is to put on rubber gloves! Yes. Ordinary household rubber gloves. Hold the jar in one hand, then use the other hand to twist the lid off. Thi...
Take one of the guys, tie him in the center of a really big metal hula hoop by his hands and feet, give him a helmet cam, then kick him in the balls and roll him down a big hill.
Whenever we make a homemade circuit, we use what are called through-hole components. Any components with long metal leads is a through-hole component. They are great for soldering to, but it's tough to fit enough through-hole resistors and capacitors into a smartphone. To get those last microns, we have surface-mount components for SMDs (surface-mount devices). These are all of those teeny, tiny things you see when you crack open your digital camera or laptop case.
Wall studs are both critical for maintaining the structure of your home and supporting items of weight and function on the interior walls (e.g. cabinets, shelves, plasma TVs, etc.). With wall studs playing such a critical role, consistently being able to find them is important. The problem with finding them is that drywall and wallboard isn't exactly see-through.
I think it's fair to say that every maker yearns for a 3D printer. You can replace circuit board connectors, fix your glasses, create ski grips, and make whole machines out of printed plastic parts—even a 3D printer. But without a 3D printer on hand, you can always resort to Sugru.
If you've ever been inside of a real laboratory, you probably noticed how expensive the equipment is. You'd never be able to afford even just one of those ultra high-tech machines required to splice genes or split atoms. Even the lesser machines can be prohibitively costly, including a stir plate.
This is the third part of my electromagnetic pulse series (see Part One and Part Two). By now, I've covered the hardware and general concept of electromagnetic pulse generators, but how exactly do they disable electronics? How can an invisible field of energy have such a catastrophic effect on computers, cell phones, and most any other electronics? I'll be answering all these questions in part three of Making Electromagnetic Weapons.
You can make homemade pizza with a minimum of tools, or you can buy the entire yuppie menagerie (and let's face it—if you're a foodie, you probably want the toys). Below is a brief rundown of the different options available. Since I'm a relative beginner to the process, I've also linked out to a few in-depth reviews.
What you do is you go to different places dressed as old men and when death metal or thrash metal plays, you start a mosh pit and when the music stops you go back to being old men
In this article, I'll be showing you how to make a simple yet effective static electricity generator. Basically, this device allows you to carry a constant static charge on your body and discharge it on anything grounded or of opposite polarity. The electricity generated is around 8-10 kV, at a very low current. The shock is enough to startle your friends, just like a static shock from a trampoline or carpeted room. You'll need a little experience in soldering and circuit design to build the ...
In this article, I'll show you how to create a simple yet accurate demonstration of the "rising ionized gas" principle. In other words, a transformer, two metal prongs and lots of evil laughter. Remember those large "towers" in the background of Frankenstein movies with a "lightning bolt" rising upwards every few seconds? That's called a Jacob's Ladder; one of the coolest awe-inspiring demonstrations of high voltage. Here's a video of the final product: Materials and Tools
National Ignition Facility
Piezoelectric Energy In this article, I'll show you how to make a small, wallet-sized device that generates electricity from kinetic energy. The concept is simple: Piezoelectricity is the charge that is produced when certain solid materials (commonly ceramic and crystal) in response to mechanical stress. Piezoelectrics have many applications; in speakers, actuators, sensors, even fuses. For more information, click here.

No matter if you've used one or not, you've got to admit that 3D printers are pretty darn awesome, especially the self-replicating ones that extrude molten plastic and the shoebox-sized versions that use mesmerizing stereolithography to build tiny objects layer by layer. But what's even cooler? A solar-powered printer that uses the sun's energy to melt sand and make 3D objects out of glass.
Although in recent years street art has reached a high point of public appeal many of the great artists are over shadowed by the likes of banksy and shepard fairey (who are amazing artists for sure, just not the only amazing artists out there). Some of the best urban artists have never had a gallery show or exihbit, and most have only been out of their own country once or twice. But of course, thanks to the internet and movies, i )along with many others) have been lucky enough to see the work...
After stumbling across an interesting article by Hanne Blank—(apparent) hobbyist chef and widely known activist on the issues of weight, bisexuality, and sexuality—I've become even more fascinated by kitchen shortcuts. Former Microsoft CTO Nathan Myhrvold's recently released Modernist Cuisine also spurred a similar interest, particularly after reading a WSJ piece in which Myhrvold attests —by law of science, of course— that a ¼-inch-thick sheet of steel is more than adequate in place of an ex...
One of the creepiest musical instruments ever is undoubtedly the theremin, a device originating from the early 20s that emits eerie sounds with a just a wave of the hand. If you've seen the original movie The Day the Earth Stood Still, you know what I mean—freakishly creepy. Playing the theremin can be off-putting for some, since it's a relatively pricy gizmo, but a new geek gadget called the EaTheremin aims to make all of us professional, dinnertime theremists.
'Tis the season for Christmas tree decorations and everybody's favorite board game— SCRABBLE! Okay, that was too ebullient on my part.

Gil Adam, a student of Industrial Design in Bezalel Academy of Arts and Design in Jerusalem, Israel, has created a 3:1 scale model of his favorite plastic camera, the Holga. While the camera is just a model (non-operational), it's pretty fun to see the oversized object next to Adam's face, and his dog.
