• The 3D Printing Revolution gets its First Pen

    Boston toy company Wobble Works uploaded a pitch video to Kickstarter of its newest toy, the 3Doodler, awaking a sleeping desire to write in 3-D.

    The 3Doodler, a plastic extrusion pen that resembles a hot glue gun, heats up plastic filament to about 270 degrees Celsius, or 518 Fahrenheit. But unlike a glue gun, the plastic cools almost instantly, allowing you to lift the 3Doodler off the paper and draw in air.

    In the Kickstarter video, the moment the pen was lifted off the surface to make a simple 3-D box donations came in at a frantic pace.

    Almost immediately, the company surpassed its modest goal of raising $30,000 – so far, it has raised more than $2.1 million, with more than two weeks left to go in the campaign.

    Wobble Works sees its latest gadget as an introduction to 3-D printing and intends to sell the 3Doodler for $75 apiece. Owners can download stencils to create different shapes, or upload their own.

    Even though Wobble Works has raised a ton of money, it hasn’t received a

  • Scientist Stumbles onto a Cure for Color Blindness

    Out in the world, one out of every 10 men have some form of color blindness.

    While it’s not the most debilitating genetic irregularity, color blindness can still make everyday tasks, such as getting dressed, difficult. Imagine being color blind and in a gang. That could become downright dangerous.

    Then, of course, color blindness becomes a bit of a novelty to “color normals” – as those who can see the full spectrum of colors are known -- when they first come across someone who’s color blind. “What color is my shirt!?” is a favorite question.

    But a scientist named Mark Changizi and his partner Tim Barber from 2AI Labs in Boston have created a pair of glasses that may provide a remedy for a certain type of color blindness – the inability to see reds and greens.

    According to Changizi, it turns out that color vision is a trait found only in primates with exposed skin as opposed to dogs, which don’t have color vision. We use our color vision to see the subtle variations in blood flow, on,

  • Meet the Orp smart horn. Designed in Portland, Oregon by a company called FUSE, the Orp is meant to save lives with its two-tone horn and bright, electricity-saving LED lights.

    Lead designer Tory Orzeck, who used to design shoes for Nike, said he decided to reinvent the bike horn when he noticed a startling rise in bike accidents in Portland, where he lives.

    The Orp isn’t the steel horn that you had on your bike when you were a kid, riding to the rock quarry after school to beat the hot sun. It’s a horn with a high powered, admittedly obnoxious sound like a smoke detector – good for getting drivers’ attention when they don’t notice a biker. It also has a lighter, more polite horn that can used to say hello to a passing pedestrian.

    While Mr. Orzeck was putting the horn together, it occurred to him that he could add high-intensity LED lights that wouldn’t drain too much power from the horn, and thus the Orp was born.

    To raise money they went to Kickstarter, where they raised $110,000
