LEGO has not attempted a blimp, zeppelin, or similar airship since 1999, the 5956 Expedition Balloon which used highly specialized parts. This is unfortunate as these vessels are well and truly part of the pulpy adventure and steampunk scene.
Earlier this month, Adam Cudworth, 19, launched a camera attached to a weather balloon into the edge of space.

Simon Leach teaches us how to glaze trailing and pouring for pottery. First, you will dip the entire pot into the glaze after you have poured it into the middle. Wind up your wrist as you are pouring it out so you cover all of the sides in it. Just dip it down a little bit so it goes over the edge of the tip to cover the mouth of it. To use a balloon wand, fill it with the glaze and then use this to glaze the pots. Simply drop the liquid onto the pot in straight lines as you are turning it wi...

There has been much talk about how unsecure the cloud is because of PRISM’s newfound ability to demand all of your data without any resistance. This has spin doctors in the Cloud Storage industry losing their mind. They suddenly went from a central hub for 10GB of your files, to an easy window for Big Brother to track you through. Centralized cloud storage is no longer a safe way to keep your files, but we still need a way to access our files anywhere we go.
I was kinda disappointed with last year's James Bond movie, Skyfall. Don't get me wrong, it was a solid flick, but only made me jealous with all its super spy hacker stuff.
We've all seen the classic tornado-in-a-bottle science experiment, which uses 2 two-liter bottles to create a whirlpool effect. This version requires you to get the tornado started yourself by spinning the bottles, but what if you want to make it fully automated?
Eavesdropping from a distance can be tricky because it usually requires some sort of bug or transmitter. It's easy to transmit audio through lasers, but you can also use lasers to build a microphone that picks up audio from a distance. LucidScience built the Laser Spy System for about $20. To make your own, you'll need a cheap laser pointer, an NPN phototransistor, a headphone amp, and a few other small pieces listed below. A light-to-sound circuit is installed in a small plastic box with the...

He used an iPhone and an iPad to start a FaceTime chat, then taped ...

Have a super secret spy communication you'd like to send out, but don't have the funds to hire your own trusted operatives to deliver the message? Then stick to what you're used to—email it. SafeGmail is a browser extension that allows you to send encrypted emails right through your regular Gmail account. While this may seem a bit unnecessary for most messages, encrypting your email can definitely be useful.
Looking to transmit some super-secret audio communications to your other spy buddies? A laser is the perfect tool for getting your sounds heard from a small distance—without anyone intercepting them— even if it's just a cover of your favorite pop song. A laser audio transmitter uses light rather than radio waves to transmit sound. This is a much more secure way to send audio communications because the laser is a focused beam of light, whereas radio waves are not controlled, so they can be pic...
Gerridae—you've probably seen these weird bugs gliding across the surface of the water when you're out swimming or fishing.
