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.
Most people have had the unfortunate experience of not having a washer and dryer at some point. Apartments in my area tend to charge at least one hundred dollars extra for the units with washer and dryer hookups, and even more if you want a unit with an actual washer and dryer installed already. If you are young and just starting out, this may be hard for you to manage with your current salary. If you have no washer and dryer, the only alternative is the laundromat.
Permanently deleting files is something that a lot of people aren't aware of. Actually, most people think that once a file is deleted, it is gone forever. This is not the case. Hard drives write to the disk via magnetic charges, positive and negative correlate to 1s and 0s for binary. This is then interpreted into information for the computer to use and access.
It's only been ten years? Where has all of the time gone? When RuneScape came out in January of 2001, the world was a different place. There were no such thing as Xboxes, normal gamers didn't care about the number of cores on a processor, and the World Trade Center Towers dominated the Lower Manhattan skyline.
Need to pick up some furniture, but can't find any free time in your busy schedule? What if you're just too lazy to go pick up some cat food? How are you going to feed your pet without getting off the couch? Tired of waiting in lines at the post office to mail out some last minute package?
Lady Gaga and Polaroid's upcoming Grey Label Camera Glasses can record video and snap pictures, but who really wants to show the world what they're up too on those mini LCD screens? It's nothing more than a fancy gimmick between a pop star and a failing company. Isn't the intention of camera glasses to capture things around you as they are? Drawing attention to yourself with clunky video-displaying eyewear kind of defeats the purpose, but that's why they're "fashion" glasses and not practical...
After getting slammed with a crazy-big earthquake/tsunami, the Japanese nuclear plant Fukushima Daiichi might be on the brink of meltdown. Not as bad as Chernobyl, but maybe as bad as Three Mile Island. Nobody wishes such a disaster on anyone...anywhere in the world. In the US, there are about 100 nuclear facilities, about 8 of which are located near hot beds of seismic activity.
Tomorrow is another day of election (PSG). I have to wake up early to set up the computers on both computer rooms. The election process is computerized, making the counting of votes the responsibility of the computer. What makes this year's election special is that for the first time in 3 years (correct me if I'm wrong), there are competing parties. The result is something to look forward to especially for me who contributed in the creation of the system.
Hey wizards! As you have read in the gardening article I put up a few days ago, it requires the Test Realm! It's pretty easy to use the Test Realm, but there are a few very important limitations you have to pay attention to before using it. Many of you reading this may be pretty agravated. Here's how KingsIsle puts it:This Test Realm is available to Subscribers.
Congrats to WonderHowTo Jackass 3D prank contest winner Grayson Robison! His winning idea: Connect Knoxville to a real life Operation game with shocking devices. Every time a player screws up and the buzzer goes off, the "patient" gets a burning shock to the correlating body part.
LIFE magazine has posted a gallery of bizarrely wonderful old school scientific models. Don't miss the giant fetus or massive colon (double ew). Behold, science education before computers ruled our world.
Feeling comfortable or at home means living in an atmosphere where you are accepted. Some people moving abroad worry about getting adjusted to the new social environment or the western culture. You may have left your home to make big business, excel in your career, get married, meet a relative/friend, discover new places, or for any good reason.
If you look up the word SAWBUCK in the SCRABBLE Dictionary, you'd see that it was a sawhorse, but there's another definition that we're all probably more familiar with:
Flash video. It's what all smartphone users have been waiting for. Why has it taken sooo long? And why is Apple still resistant?
What is in store for the future? Flying cars? Maybe. Dinner in a pill? Perhaps. How about 4-legged army tank robot dogs? Hell ya!
Gas prices across the United States have skyrocketed, with today's national average for regular unleaded gas at $3.51 a gallon, with California leading the pack at $3.90 a gallon. AAA reports that last week's national average was just $3.37. That's a $0.14 increase in just one week! Just one month ago, the average was $3.12. A year ago—$2.75 a gallon. Actually, the U.S. Energy Information Administration (EIA) states the price of gas hasn't been this high since since 2008 when it hit $3.57 in ...

First Things First Before you can begin to work on a damaged panel, you must determine what type of material that you are working on. For instance, the panel may be mild steel, high strength steel, aluminum, plastic, sheet molded compound, or a number of other types of material.
Wouldn't it be nice to just sit at your buddy's house, plug into his network, and see exactly what he's doing? What if it was as easy as that? What makes packet sniffers like Wireshark such potent tools is that a majority of local area networks (LANs) are based on the shared Ethernet notion.
It's been a long journey for Netflix users. At first, it was a rough ride as Netflix struggled to find its place in the homes and hearts of movie watchers everywhere. Once monthly subscriptions bumped off the pay-per-rental charges, Netflix soared to great heights, known for their flat-fee unlimited rentals without due dates, late fees, or shipping and handling fees. And it was smooth sailing when streaming services were incorporated into monthly plans, with customers being able to rent DVDs ...
Before you go running off to the Apple store, you may want to educate yourself. DVICE is kind enough to compile the 20 biggest complaints about the iPad from a whole slew of reviewers.
Have you ever noticed that whenever you setup your voicemail account after getting a new cell phone number, it asks you to create a security pin to access your voicemail from other phone lines?
Prank Calls, Masked NumbersWho is calling your phone or your child's? Pranksters use a lot of tricks to make sure they can get on your nerves. Being able to trace prank calls is important because you're not going to learn much from your Caller ID, since most prank callers use an unlisted number - such as, a cell phone number. Many also use special code *67 to mask the number so your Caller ID will show "Blocked Number" or "Private Number". There are a lot of mild cases of so-called phone bull...
Much like when Rabb pee'd on the Electric Fence you Rigg a Urinal, or a Toilet to have a slight Electric charge. Not enough to cause damage but enough that they'll feel it and get a good shock.

I'm back with the third part to my laser weapon series (see part one and two), and I'll be explaining the function, application, and potential of semiconductor lasers, aka laser diodes.
I'm sure we've all heard about MSN and Yahoo! Messenger, right? They can be useful, but the setup can be quite time consuming for those who need to use it just once or twice—and the privacy statements are a real bother. For example, we must provide our real details. You could use Fake Name Generator, but if you get caught, you will have your account suspended. I don't have a law degree, but to my understanding the United States recently passed legislation that gives the authorities the power ...
In this article, I'll show you how to make a glowing orb. The orb is a fun, round flashlight useful for lighting your path in a magical way. Consisting simply of LEDs, a tennis ball, a battery and a switch, it's a great simple project for beginners with electronics. Here's a video of it in action: Tools and Materials
The big day may be over, but the weekend is still full of Thanksgiving spirit. And so is this week's puzzle. But let's keep it short this time, because we should all be taking this time to play a real game of Scrabble with friends and family. I was thinking of making a puzzle about edible birds in general, but practically every bird is edible, meaning there's a lot of avian-related words. Since the turkey is such a big part of Thanksgiving, let's just stick to that...
Last year, Hasbro unveiled Scrabble Flash, an electronic version of the popular word game which consists of five SmartLink letter tiles that can communicate with one another using near field communication (NFC) to spell and score words. It's an interesting (and fun) way to build your Scrabble vocabulary for words ranging from two to five letters, but that's about it.
It's a hell of a lot easier to make money selling an indie game now than it was four years ago. But it's still a rough game.
Making a video game requires an incredible amount of work. It requires people skilled in many disciplines to work together for thousands of hours merging visual art, computer programming, game design, sound design, and music composition into a fun game. The Indie Stone is a Scottish indie development studio started, like so many others, by industry vets who were tired of corporate restrictions and wanted to make the crazy games they had always imagined.
For a long time, video games manuals were serious business. Especially for strategy games and RPGs on the PC, the manuals would often run to a hundred or more full-color pages in length. They explained in vivid and well-written detail the history of the game world and every facet of the gameplay system. There were pages upon pages of appendices explaining the statistics of every unit, faction, and terrain type. They were majestic, and I would spend an hour or more poring over each one before ...
Steam has been a game-changer in the PC indie game market over the last eight years, making smaller games available to millions of users at lower prices than ever before. And few times in those eight years have there been as much indie awesomeness on sale for as little money as this weekend.
Giveaway Tuesdays has officially ended! But don't sweat it, WonderHowTo has another World that's taken its place. Every Tuesday, Phone Snap! invites you to show off your cell phone photography skills.
Video games consoles have long wanted to be more than just consoles. Nintendo Japan called the NES the Famicom because they wanted to make it the sole family computer. Obviously that didn't work out, and most efforts to make consoles into all-in-one entertainment systems have had similar fates. Sony has done the best job with the Playstation consoles, probably because they have experience with other types of electronics that most video game companies do not.
