I'm sure most everyone has some kind of fluorescent light source in their home; those long white tubes that emit a bright white light when turned on, or maybe a few of the CFL power-saver bulbs. These bulbs actually require very little "power" (i.e. a high voltage:almost no current ratio) to emit light. In fact, static electricity is enough to make them flicker. Inside these tubes is a gas, and when electricity flows through that gas, it gets "excited" and produces light.
A nice little series of videos where you witness live social engineering and listen to others share their funny little stories where they were able to use their skills. Definitely worth a watch if you're into this sort of thing!
This parkour map seems nearly impossible for the standard Minecraft player... to build AND to jump! Can you imagine being the one to set the timing for the boats/pistons? I'd certainly go mad...

No longer do you need to crowd around your tiny smartphone to watch a funny YouTube video with your friends. If you've got a display nearby with a web browser and internet access, you can take control of it with your mobile device for free with the new Clik app.
SSH is amazing, and we praise its existence on Null Byte for many reasons. Notably, it allows us to reroute our traffic through encrypted ports on our local host to be sent to its destination when on the go. You can even control your home computers remotely over a secure and encrypted connection. This is handy for a multitude of reasons.
These lovely scarves have different names. I call it the Spiral Ruffle Scarf. It's easy to make and looks great in either a fine or a medium weight yarn. I made mine with softball cotton yarn and size 8 needles. Here are the videos and written directions:
In each day of our life, we see inflammation. We see it during sore throats and abscess formations in our bodies, and even slight tooth pain is a form of inflammation. Sometimes it's good when it fights to protect us from invading organisms, but sometimes it becomes bad when it occurs in inappropriate ways, like acne.
BebopVox filmed this great run-through of the new 12w07a and 12w07b Snapshots. He goes over what's changed, and some of the current glitches.
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.
His name is Don Pettit, but I like to call him Space MacGyver. He's well known for his paper clip fixes and ingenious coffee invention in zero gravity, and we've all seen the NASA astronaut in his Saturday Morning Science videos during his first stay on the International Space Station. And now he's back on the ISS with a brand new physics-related show... Science Off the Sphere.

In my last article, I discussed how you could download almost any video from almost any video sharing site using the free NetVideoHunter add-on in Mozilla Firefox. Now in this article, I will discuss how to convert those videos you’ve downloaded to any format—also for free. Most of the time, the videos you download with NetVideoHunter are in FLV (Flash video) format, which is something that not all video players can play. That’s why I made this article.
In a previous article, I showed how to make a powerful airsoft BB machine gun with a portable air supply using about $50 worth of PVC and air fittings. For this project, I have simplified the design to make a machine gun out of only 4 parts totaling about $15 that runs directly off of an air compressor.
Here is a step-by-step video guide on how to create your own homemade pop filter for your recording microphone, using easy-to-find materials. A pop filter is used to prevent popping sounds while recording. Most pop filters range from $15 to $80. This particular pop filter costs much less, and you can make multiples of them.
There are many websites that let you watch videos, but that don't let you download it for later viewing. Even if there is a download option, most of the time it requires you to pay some amount of money. Luckily for Mozilla Firefox users, there is a way to download the videos you stream for free.
1.) If you do not know something, keep our mouth shut.* No-one, I repeat no-one, is interested in your uneducated guesses about why something is the way it is, or why someone did something a certain way. At best, you will trick them into temporarily thinking you know what you’re talking about. At worst, you will convince them that you are speaking the truth and they will perpetuate your bullsh*t to others. Do not contribute to making the world a more foolish place just because you had to say ...

When it comes to webcams these days, most people are using their laptops over desktops. The cameras are centered, integrated, and require no configuring. They're a cinch and usually have great resolution. So, then what do we do with all of those old wired desktop webcams that we've accrued over the years? Even if you still use an external USB one, chances are you're not using it daily, so why not come up with a better use for it?
Do you need proxy access, but cannot have it for some reason? The most common perpetrator behind the issue is the network you're trying to access the pages from. Some networks will block websites, then go as far as filtering out all of the web queries for terms like "proxy" because it can get around their filter. Quick web proxies can be used for tons of other things, though.

Welcome to Minecraft World! Check out our advanced tutorials and come play on our free server. This past weekend, our Weekly Workshop focused on building a suffocation trap. But today, we're going to be covering a different type of redstone trap in Minecraft—one with a 100% success rate (perfect for PvP servers).
Does this video prove that otherworldly intelligent life has visited Earth? No. It does not prove anything other than there are designs ‘etched’ onto the surface of a field. Does the video immediately above prove that otherworldly intelligent life hasn’t visited Earth? Yeah, you saw it coming; no, it proves nothing more than humans are able to ‘etch’ designs in a field of grain.
With Valentine's Day right around the corner, it's time for some heart-origami! In the video below, see how to fold a winged origami heart. General Information
In this article, I'll be showing you how to make a cool visual representation of sound using an old cathode ray tube (CRT) television, a stereo, and a sound source. You'll also need a pair of wire cutters, and a few screwdrivers. To properly understand this project, it's a good idea to learn a little bit about how CRT TVs work. Check out this article on how they work.
This sweet little knitted heart cushion is easy to create and makes a lovely gift. It can also be used as a sachet. Here are the directions.
Despite starting on Macintosh computers, Avid focused their non-linear video editing programs on Windows systems after stiff competition from Final Cut Pro. But now they're coming back around, with Avid introducing their first iPad version of the Avid Studio home editing software, a miniature version of their industry-geared Media Composer. It will be directly competing with Apple's own iMovie for iPad.
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

Nikola Tesla. He was the man behind some of the greatest inventions of all time, including radio and alternating current. But perhaps his most visually fascinating invention is the Tesla coil. While maintaining a low current, it can produce dangerous high frequencies and voltages that can well exceed 1,000,000 volts, discharging it in the form of electrical arcs very similar to lightning.

Sometimes your pattern will ask you to purl in the back of a stitch. This tends to twist the stitch and make it tighter. It's easy, and here's what you do.
When it comes to coffee, some people just like perfection. Most would agree that the best cup of coffee comes from home, after roasting your own green coffee beans. But not everybody has the time or money to have complete control over their coffee's flavor. Roasting via stovetop or oven produces mélange (not quite perfection), and home roasters can be pricey.
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...
