NASA is already experimenting with 3D-printing components for rockets to Mars, but the fun doesn't have to stop at liftoff.

Researchers at Washington State University and NASA are suggesting that rocks on the moon or Mars could be used to print useful objects like tools or replacement parts.… Read more

You know that greasy bike chain sitting in the corner of your garage? Take a look at the below gallery of original art made from bicycle components, and you might think twice about getting rid of it.

Chicago-based bike parts company SRAM gave a group of handpicked artists a box each of 100 high-performance bicycle components and told them to craft something amazing. They responded with everything from a bike-centric interpretation of Vincent van Gogh's famous "Starry Night" to a robotic ostrich, a crawling "Sramantis," and your typical Mary Jane-wearing bike chain quadruped with a plastic baby head. … Read more

Sometimes it's hard to say "no." You get an e-mail from a friend who wants you to read, critique, and edit his 500,000-word epic sci-fi fantasy novel. Your boss wants you to forfeit the next 12 weekends to help out with a pet project. This is when you need to have the Semi-Automatic Gmail Assistant (SAGA).

SAGA looks deceptively simple. It's a colorful rectangular box with a chrome button, a place for a key, and a USB hook-up for your computer. Your computer sees it as a standard keyboard.… Read more

Despite my small fear of bugs, there's just something creepily cute about these mechanical insects by Justin Gershenson-Gates.

Gates, a self-taught tinkerer, usually sells jewelry accented with watch gears on his Web site A Mechanical Mind, but people can't seem to get enough of his occasional arthropods made from watch parts, tiny lightbulbs, and other bits and bobs.

In an e-mail interview with Crave, Gates revealed the inspiration behind these creepy designs: a recent trip featuring a freak spider encounter -- "with a leg span of about 3 inches," he says -- prompted the idea. After returning from vacation, Gates created a set of spider legs with watch-winding stems and tacked on other watch parts to create his first spider. … Read more

Photographer Clayton Cubitt is using some of his recent, slightly naughtier work to entice donations for Hurricane Sandy victims, but with a unique Instagram- and Twitter-based twist.

For every $200 donated to Occupy Sandy Recovery, the photographer based in New York and New Orleans releases one of his sexy #babesofsandy photos on Instagram.

So far we've only seen two storm babe shots, including one that's complete with the requisite DOLCat (drooling on laptop) and another that would would win the approval of Sir Mix-A-Lot. With a little more attention to the cause, hopefully Cubitt will need to fill a few memory cards with some more sexiness soon.… Read more

Online retailers will begin selling a 4.5-inch-wide Intel-branded desktop PC for do-it-yourselfers later this month.

The product name is a mouthful -- the "Next Unit of Computing," or NUC for short.

"It's geared more to home theater/home media center," said Intel spokesperson Dan Snyder. One usage scenario he suggested: slap it on the back of a wide-screen display (see photo below).

But note: as Anandtech points out, it is truly a bare-bones system aimed at DIYers. … Read more

In a stroke of ingenuity that could have proven handy during Hurricane Sandy, four teenage African girls have come up with a urine-powered generator.

Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin, all 14, and Bello Eniola, 15, collaborated on the invention, which they claim generates one hour of electricity from one liter (about a quart) of urine.

The pee-powered product made its debut at Maker Faire Africa in Lagos, Nigeria, this week. A post on the Maker Faire Africa blog describes the generator's workings in the following words: … Read more

Bob Dylan famously sang that the times they are a-changin' -- but little did he know just how much. So much, in fact, that a MIDI-controlled orchestra made of old consumer electronics can now play one of his all-time classics.

Chris Cairns of production company Partizan teamed with creative firm Isthisgood? to turn old Brother photocopiers, scanners, fax machines, printers, hard drives, and modems into a full-scale scrapheap symphony with a penchant for folk.

They soldered, reprogrammed, hacked, and rewired 97 printer relics destined for the landfill and even custom-designed their own circuitboard that could control all of the printers from one main computer. … Read more

Van Halen's tour contract once famously included a clause that a bowl of M&Ms was to be provided backstage with all the brown ones removed. Such a feat would be a lot easier to achieve today using a device like the Skittles Sorting Machine.

The Skittles Sorting Machine does exactly what it sounds like. Pour Skittles into a funnel at the top and wait as the machine patiently evaluates each one and delivers it into a bowl with like colors. Once done, you can taste the individual colors of the rainbow.

The machine is even more impressive when you learn maker Brian Egenriether fabricated many of the parts from epoxy, pulled the funnel from a hummingbird feeder, and poached additional parts from a telescope.… Read more
