How To: Electron Spirographs with a Cathode Ray Tube

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.

News: Block-N-Roll Lego Marble Run Construction

I happen to love Marble Runs as much as I do my Legos.  Here are a series of Block-N-Roll Marble Runs I have made.   What is so cool about Block-N-Roll is that they attach to any Duplo Lego pieces so they are perfect for building marble runs around your lego world.  The pieces not only attach to Duplos but they attach to each other so you can have long runs in between your support beams.

News: Japan's Flying, Tumbling Reconnaissance Sphere Soars at 37 MPH

Flying orbs. At first, you might think of the Tall Man and his army of flying sentinel spheres, equipped with zombie brains and a mini-arsenal of saw blades, drill bits and shooting lasers. But these flying orbs weren't conceived from the evil mind of a superhuman mortician—they were designed by Fumiyuki Sato, a researcher at the Japanese Defense Ministry's Technical Research and Development Institute—for something other than deadly deeds.

MovieReshape: Coming soon to a pair of glasses near you!

Imagine walking around and everyone looks awesome! Ok, maybe this beauty is only skin deep or shall we say AR deep. Coming soon to a pair of glasses near you, you will be able to put on glasses that actually make people look more muscular, have bigger boobs, look tan & blonde, etc...

How To: Print Your Emails in Style with This Steampunk Tape "Ticker Machine"

Last year, Instructables user Horatius.Steam created Dr. Brain, a small computer connected to a model brain that can tell stories and have Skype conversations. But one thing it couldn't do was print, so to solve that problem, he came up with this awesome Steampunk "Ticker Machine". A wooden base and glass dome make up the housing for a thermal printer, and the driver is hidden in a paper tube that's painted to look like wood. A slot at the bottom feeds the paper out from under the dome and a ...

How To: Turn a Boring Old Flashlight into a Steampunk Star Wars Lightsaber

There are tons of uses for a flashlight. You can turn it into a laser, hack it into a night vision flashlight, or make it super bright. Or if you're a Steampunk Jedi, you turn it into a steampunk lightsaber. Jen from EPBOT started with a vintage flashlight and attached a piece of plumbing extension pipe. Screen splicing was glued on with E-600 for the grip and brass mesh with buttons and rhinestones makes up the 'control panel.' She added a silver gear to cover up the logo on the end. The LED...

News: Laser-Etched Scrabble Coasters Look Like Legitimate Letter Tiles!

If you're not into making your own Scrabble coasters out of Scrabble tiles, these are the next best thing (though a little more complicated). And better than having tons of tiles on the same coaster is just being one tile itself, so you can make words out of the coasters! Though these are undeniably cool, Pete Prodoehl of RasterWeb!, the mastermind behind these coasters, is calling this his beta versions. Why? Some minor problems with sanding, cork, and staining. I still think they look prett...

News: If Cats Could Play Scrabble...

Do you think humans are the only ones who like the challenge of a good word game? Well, think again, because homo sapiens aren't the only ones up for stimulating their brains. Other species on planet Earth like to play Scrabble, too, and they're the ones most likely to actually play the words HOMO and SAPIENS in a game, both totally legit Scrabble words... by themselves, of course.

News: FOX News Outraged Over Liberal Eco-Minded Kids Games

We've all seen FOX News commentators get worked up about silly non-issues. It occurs more than we'd like, but what happened last week on popular morning show FOX and Friends was not only a misleading and pointless attack on video games, it was an unintelligible attack on a mediocre and forgotten game from 2007, along with a handful of recent indies that no FOX and Friends viewers, or any of their close family members, had ever heard of before this broadcast.

News: Team Building Excersize

Sign up for group laser tag as a team building opportunity. All but one will be equipped with paintball guns and neon paintballs.

News: Man Builds Camera as Big as His Dog

Gil Adam, a student of Industrial Design in Bezalel Academy of Arts and Design in Jerusalem, Israel, has created a 3:1 scale model of his favorite plastic camera, the Holga. While the camera is just a model (non-operational), it's pretty fun to see the oversized object next to Adam's face, and his dog.

News: Do Cats & Boobs Belong on Google+?

While using Google+, it's been apparent that there are two types of posters. There are the people who post thoughtful, serious posts about everything from tech to dealing with cancer. And then there are the meme propagators, the people who decide to rick roll others (ahem, +Bryan Crow), and constantly put up animated gifs. Sometimes they are the same people, and this is where it gets a little controversial.
