In this article, I'll show you how to create a simple yet effective way of scaring off intruders. Of course, there are methods around this approach, but it's great for office pranks and general fun. The project requires a little background knowledge in electronics and circuitry, like reading schematics and using a soldering iron.
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.
In this series, I'll be exploring electromagnetic weapons, how to build them, their function and application to the future, and the amazing possibilities electromagnetism has to offer. First, the electromagnetic pulse generator, or EMP. You've probably heard of these before, and their devastating effects on electronics. A simple EMP consists of a capacitor, transformer, trigger, and coil of copper wire. This, when triggered, would produce an intense magnetic field for a brief period, similar ...
In this article, I'll show you how to build a coil gun. A coil gun is a device that fires magnetic projectiles at high velocities, using electricity. Coil guns require no explosive propellant, therefor can be fired an infinite amount of time, providing that there is ammunition and available electricity.
Skyrim really took the cake this year. With its awe-inspiring gameplay, much improved combat and leveling system, and a fresh new look, it's no wonder the game has already received a Game of the Year award. But for hardcore gamers, the fun may be over. You've played the game for thousands of hours, and have exhausted the entire game's main and auxiliary quests. You need more.
In Monday's post, we created a sliceform model of a hyperbolic paraboloid. In today's post, we will create a similar model using skewers. The hyperbolic paraboloid is a ruled surface, which means that you can create it using only straight lines even though it is curved. In fact, the hyperbolic paraboloid is doubly ruled and is one of only three curved surfaces than can be created using two distinct lines passing through each point. The others are the hyperboloid and the flat plane.
Halloween will be here in just over a week, which means next week these Scrabble Bingo of the Days will become more horrific. This week, there's just a few relevant Halloween seven-letter words for your Scrabble vocabulary, referencing witchcraft and one of the eeriest horror movies of all time, The Thing (not this year's version).
The war between horror movie monsters has been going on for the better part of the last century. We're talking vampires, werewolves, ghosts, zombies and mutant flying creatures, each of which has had their fair share of the limelight in film. But it comes and goes. Once moviegoers get an overdose of a particular monster, they aren't scared anymore, meaning it's time to move onto the next. So, Dracula goes away kicking and screaming, just to be replaced by Frankenstein and then werewolves. But...
Grand Theft Auto 3 was the biggest video game of the last decade, by far, introducing open-world adventure games to consoles, a genre that now rivals shooters and sports games for market dominance. A huge map, decentralized narrative, and myriad of interlocking quests and objectives that happen in a flexible order all became hallmarks of the "new" genre, along with the ability to shape the morality and reputation of your character. And most importantly, all of the quests and stories are compl...
Facebook games are ostensibly all about connecting their players. Yet, in many ways they exist on an isolated island. That's one of the reasons traditional gamers and game franchises have avoided Facebook in the past. And all of the breakout hits so far on Facebook have been cheap PC game ripoffs from the 90s, like FarmVille and ports of other popular casual games.
The Tokyo Game Show (TGS) is the biggest video game expo in the most game crazy country on Earth. It is kind of a big deal. As such, their "indie" game showcase/contest Sense of Wonder Night (SOWN) is a major opportunity for developers of all shapes and sizes to showcase their work to important industry leaders and expo attendees. 2011 will be SOWN's fourth year, and it began accepting submissions yesterday.
A few weeks ago, I wrote about why I think streaming music services like Rdio.com are better than Apple‘s iTunes Music Store. This week, I follow up with a how-to about Rdio for Mac, a desktop music player that streams music from your Rdio.com account. Even though Apple is introducing new iTunes features, I think you will find Rdio for Mac a much more affordable option—especially if you like to listen to new music on a weekly, or even daily basis.
This week, Apple announced the beta version of its new wireless, cloud-based service, iCloud. I wrote a summary of it here. The iCloud service includes some new features in the latest version of the iTunes Store, which allows you to access all your iTunes songs, mobile apps, and eBooks purchased in their respective iTunes stores and download that media to up to 10 of your devices—your iTunes supported Macs and PCs and mobile devices. This downloading can all be done wirelessly without you hav...
Most employed in the game industry have two-word job titles that start with “game”—game designer, game producer, game critic, game tester, etc. Usually, they’re one or the other, even though some can be both a game designer and a game tester or game critic and game tester. And rarely does one person get to call themselves a “game everything”. Ben “Yahtzee” Croshaw is the exception.
Description: Admit it, having thousands of valid email Ids give you the power to do anything! Such as adding thousands of friends to your Facebook, MySpace, Twitter, etc profiles or promoting your article or blog in just a single click and much more! But how do we do it? I searched all over the internet in a hope to get a perfect email producing software but ended with just two -
Chicago Sun Times movie critic Roger Ebert hates 3-D. And when I say hate, I really mean hate. Check out Ebert's excerpted nine points below via Newsweek.
Remember KODACHROME? That color reversal film from Kodak? The film that was the inspiration for Paul Simon? The only brand of film to have a state park named after it?
Sitting in the dentist’s waiting room, I found I couldn’t browse the internet on my smartphone anymore. My eyes were tired from reading and there were no headphones to listen to music. There are no magazines at this dentist’s office, just an old TV playing Russian music videos ad nauseam. Mostly female Russian singers, and curiously enough they all shared similar traits: they can’t dance. They look gorgeous, but the best they could do is small movements and two slow moves at best- a huge diff...
Do you do last minute cramming before you go to the dentist? No, I don't mean reading up on orthodontia in hopes of having an intellectual conversation about crowns with your dentist (how you can talk at all with all those tools in your mouth is beyond me, though dentists always ridiculously try).

The Stun-Gun In this article, I'll show you how to make a small, weaponized highlighter. Before I get into how to built this device, let me warn you. This device is harmful! When used, it can cause burns and/or serious muscle spasms. The voltage is potentially deadly! DO NOT attempt to build this device unless you are experienced with safety, electronics, soldering, and understand circuit schematics.
Nearly every game takes strategy to win, but when it comes to games like Scrabble and Words with Friends, you've also got to have a lexically inclined mind full of wonderful and weird words. Most start out by learning all of the two-letter words in the Scrabble dictionary, then work their way up to three-letter words. But where do you go from there?
You wouldn't think that something so simple as a "suggested users" list would create so much controversy, but Google+ seemed to have accidentally ignited a firestorm when they introduced a new feature over the weekend: the "Suggested People to Follow" list now appears when a new user joins Google+.
Banksy, Cope2, Invader, Retna, Mr.cartoon, They all have a few things in common. Firstly, they are all extremely talented and well known urban artists. Secondly, they all have very memorable and very, very cool names.
Making your way into an online community can be really exciting. Some life-long friendships and lasting romances begin in humble chat rooms and message boards. But for the novice internet user, one of the biggest hurdles can be trying to figure out just what people are saying to one another.
It's been a long time.
A first hands look at the first chapter of the game. "When the wife of best-selling writer Alan Wake disappears on their vacation, his serach turns up pages from a thriller he doesn't remember writing. A dark presence stalks the small town of Bright Falls-"

Kick Ass Game Review Part 1: Background & Voice Talent There are three parties involved in bringing you The Kick Ass Game:
I am writing this quick post in response to the recent earthquakes and tsunamis that are affecting Japan. As soon as the news broke, and we began to hear of tsunami warning for our area, I immediately realized how under prepared I was for a natural disaster. The thing that drove this point home even deeper was the number of people asking me for advice on what they could do to prepare for the possibility that we are hit by one of the resultant tsunamis. Many thoughts raced through my mind, and...
Last week, I started a weekly feature on Scrabble World called Scrabble Challenge, where you can solve a few (hopefully) challenging word puzzles. Normally, these will be on Fridays, but today I have a potentially unsolvable puzzle for you to try and solve, in addition to the upcoming one...
My girlfriend was going away for a few weeks, but where she was going, there was no easily accessible Internet. She works mostly on the web, so it was imperative that she have a decent Internet connection during her travels. So, tethering her phone was the only real possibility.
Sometimes a simple drowning trap is too boring, and you want something that's a little more stylish and exciting. That's where this trap comes in!
So, you scratched up your $500 Adobe CD and now it's unreadable. You could go buy a new one, but you already purchased it! Searching The Pirate Bay and downloading some Adobe software can usually be easy enough, but what should you watch out for?
If you're looking to acquire the newest iPod model or latest Xbox without breaking the bank, your first stop would probably be eBay, maybe even the Amazon Marketplace, or any of the other reputable online marketplaces and auction sites. But you probably haven't hit up the penny auctions yet, and that could be a good thing, depending on how you go about it.
The last few months of WikiLeaks controversy has surely peaked your interest, but when viewing the WikiLeaks site, finding what you want is quite a hard task.
The worst can always happen. Even if you think you're absolutely prepared, you can somehow find yourself stranded in the middle of nowhere by yourself. It can happen. Without a map, without a compass, without a cell phone... without food and water.
In our media-enriched world, past and present, SCRABBLE has made a name for itself, whether deliberately, subconsciously, or influentially. You may have a read a book that had the popular word game within a chapter, watched a movie that showed your favorite characters bringing out the SCRABBLE board, or even listened to a rap about this word or that word. SCRABBLE is everywhere, even if you don't realize it.
