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.
On Tuesday night, at 9 p.m. EST, President Barack Obama delivered his second State of the Union Address before a Joint Session of Congress in the Chamber of the United States House of Representatives.
The internet is something most people rely on, so when you buy a used laptop without a wireless card or yours needs to be replaced, it's easier to do it yourself. Having someone else do it can cost more than you think, so here's an easy way if you own a Dell Inspiron E1505.
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
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.

We've all been there before: We're in a hurry to get somewhere (often in bad weather), so we get in the car, turn the key in the ignition and.....WHUH! WHUH! WHUH! The darned battery is dead! After a stream of choice expletives (that is, if you're anything like me....;o)), we open the trunk and take out the jumper cables - but what if we don't know how to use them? Even if we do, we can often forget such things in crisis situations when we're pressed for time.

I first heard the term molecular gastronomy while watching an episode of Bravo's Top Chef a few seasons back. Intrigued by the concept, I sought to find out more about this modern, deconstructed type of cookery. If you happen to be around foodies and the topic of molecular gastronomy comes up (which very likely will at some point) you'll want to have a few points to contribute and maybe even give them a run for their money.
