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 ...
Welcome to another Community Byte announcement from Null Byte! The goal of the Community Bytes is to teach people in a co-operative, hands-on manner. Learning from experience and immersing yourself in a subject is the best way to learn something foreign to you, so that is exactly what we do! In our sessions, we have started to both code and complete HTS missions. This means that there is something for everyone here, so make sure you join us.
I just found out that I might be expected to tip all the vendors... on top of the exorbitant fee they charge! Sigh... Here is a great tipping cheat sheet courtesy of theknot.com.
1. Extend your engagement. A longer planning period means a better chance of getting the best vendors in your price range. Plus, you can typically lock in rates that might increase by the time your wedding date arrives.
This video demonstrates step-by-step instructions for charging a cell phone using a USB cord. Charge your phone using a USB cable.
In my second article of the laser weapon series (see the first part here on CO2 lasers), I'll be expanding on the potential of pulsed lasers.
In this series on weaponized lasers, I'll be exploring the function, operation, strength and building instructions for three basic laser weapons; CO2, Diode, and Flashlamp. These laser types are just a few of many, selected because of their simplicity and basic construction (depending on your experience).
Find a great location, set up area with an attractive advertisement sign charging $5 for the foot bath, a recliner, foot tubs filled with poo & labeled with scented poo names and tubes of water. Each tub will have a recliner or 1 recliner then let person choose the foot bath they want. Have a table prepared with towels, and lets not 4get the foot bathers.
Graffiti is a great way of getting your message out to the masses. The earliest known graffiti dates back to 30,000 years ago and used the traditional apply-paint-to-wall technique. Though our paint now comes in cans and not from scavenged berries, the actual graffiti process hasn't really evolved from those first cave paintings.
Eventually, we plan on doing some root the box competitions here at Null Byte, but we're still looking for a server to play on. Anyone want to donate one? You won't regret it. Root the box is like 'king of the hill', except you have to hack a server and maintain access. Each server will have numerous known security holes, but until then, let's get back to the regular weekly coding sessions and realistic hacking missions on HackThisSite.
We'd like this to be one of the last HTS mission announcements, at least for now. As soon as Null Byte finds a server to play with (anyone want to donate one?), we are going to start doing root the box competitions, which is like king of the hill, except you have to hack a server and maintain access. Each server will have numerous known security holes. But for now, back to the normal flow of things...

The community tore up the first realistic mission last week. You've applied the techniques learned in the basic missions to a real scenario, so I'm pretty content. The realistic missions are where the learning gets intense and where we can apply real knowledge to extremely realistic situations. We will also be continuing the normal Python coding and hacking sessions. These sessions are created to bring our community together, to learn from each other, and grow together. Everyone is welcome, f...
In this article, I'll show you how to make a portable prank stun-baton. Powered by static electricity, simply charge up the baton, and discharge it for a static surprise. The concept behind this device ties in with Leyden jars, and their tendencies to retain static electricity.
Community byters, it's time to get serious. We are finally moving on to the realistic missions in HackThisSite. This is where the learning gets intense and where we can apply real knowledge to extremely realistic situations. We will also be continuing the normal Python coding and hacking sessions. These sessions are created to bring our community together, to learn from each other, and grow together. Everyone is welcome, from novice programmers to aspiring hackers.

Here's a noncomprehensive list of current features confirmed and experienced in Minecraft 1.8. If you have anything to add, please do so in the comment section below.
Airsoft doesn't get any better than a cloud chamber BB machine gun, aka Cloud BBMG. This design has an incredible rate of fire. If you've got a full charge of compressed air, it can easily fire more than 50 rounds per second at a 350 ft/s muzzle velocity. Since this is a legit airsoft build, it should be handled safely with the same care as any other airsoft firearm, and you should be wearing the same protective gear—protective mask, safety glasses, etc. My video details the build of this bea...
Dandruff -- the embarrassing white flakes that end up like snowfall on your shoulders and clothing. There are plenty of dandruff shampoos on the market to choose from, unfortunately, they are all very expensive. If you have ever wondered what ingredients make them so expensive, the simple answer is there are no expensive ingredients that make them so effective. So, the next question might be, why are they so expensive? And the answer to that is dandruff shampoo companies know they can charge ...
Musical boxes are best known for their kitschy designs and somewhat trivial renditions of musical masterpieces. They tend to frequent the dresser of young girls or elderly woman hanging on to their youth, and for the most part, they remain cutesy and harmless, but when featured in movies like The Silence of the Lambs and Black Swan, they become downright creepy.
Want to stick it to your mobile carrier by porting your cell number to Google Voice? Now you can! On Wednesday, January 19th, Google Voice began allowing select users to transfer their personal numbers to Google Voice for a one-time fee of $20. Though the feature is still in limited release, Google has stated that they intend to make the feature available to all Google Voice users "in the near future." Terrific, right? Not entirely!

Police in Milledgeville, Ga., say they handcuffed a 6-year-old kindergartner for safety after she allegedly threw a tantrum at school, tearing items off the principal's wall and upending furniture, WMAZ-TV reports.
Tesla coils are electrically satisfying in so many ways. But what happens when a guitar-playing city coil has a run-in with a backwoods, banjo-playing, inbred coil? A musical duel to the death! Watch these two Tesla coils battle it out as they play Dueling Banjos. Shocking. Just shocking. Okay, so it's no secret that Tesla coils can create a wonderful light show of electricity, but by modulating the frequency, they quickly turn into powerful singing Tesla coils—the key to any electromaniac's ...
Welcome to WTFoto, a community dedicated to scouring the internet for great WTF photos and encouraging you to do the same. Check out all of our upcoming weekly tutorials and competitions to learn how it's done and jump into the fray. Here's how we roll:
You might be sitting there thinking that I'm crazy, but the truth is you're only partially right. You can get free text messaging for life, all for a cheap, one-time fee. But, how can that be possible? An exploit in AT&T's prepaid GoPhones is the culprit behind this sweet, oh-so rare opportunity for exploitation. The exploit grants a lifetime of free texting, assuming that the company stays afloat from now until the end of time.
I have to say, the Xbox 360 controller is the best controller ever created. When I first held it back in 2005, I swore that the dudes working at Microsoft came over and took a molding of my hands because of how great it felt. The thing felt like it was born there.
NASA reports that the sun erupted late last night with a large solar flare—an M8.7 class flare. The classification is calculated according to the peak flux of 100 to 800 picometer x-rays near Earth measured from the GEOS weather satellite. There are 5 letter classifications for solar flares, each with a linear 1-9 number scale of severity. M is the fourth most powerful class, with X leading the way. But last night's earth-directed coronal mass ejection (CME), captured by the Solar Dynamics Ob...

If you powered up the ol' Xbox 360 last night to watch Netflix, you probably noticed that a new streaming service moved into Xbox LIVE—Hulu Plus. Netflix finally has some competition. Or maybe not. But with a week of free service, they're sure to attract some would-be watchers.
Outstanding advancements in medicine and super creepy Androids aren't the only jaw-dropping inventions out there. Every once in a while, an incredibly random—and at first glance, seemingly useless—device comes along and strikes a chord of strangely deep satisfaction. Behold, the SWITL, a mysterious goo-scraper robot hand created by factory equipment manufacturer Furukawa Kikou: From what I can glean from a very rough Google translation, it sounds like the SWITL was developed for food producti...
We love all things Jackass at WonderHowTo, but before Johnny Knoxville and his pals were sticking fireworks up their butts, snorting wasabi, and taking a shock to the gonads (à la the childhood game, Operation), in the far off land of Ontario, Canada reigned another daredevil—a man named Ralph Zavadil, a.k.a. Cap’n Video. Just as we all winced when Knoxville tore his uretha, community access viewers of the '90s cringed as Cap'n Video bounced off concrete and broke his neck... until Zavadil wa...
