With a lot of folks buying the Back to the Future 2 hoverboard prank earlier this year, it's no surprise that a purportedly real hoverboard just got funded on Kickstarter. (Or so we assume—at press time it was at $234,708 of a $250,000 goal, with 53 days left to pledge.) "We aim to get this technology into everyone's hands (and under everyone's feet)!" writes Hendo Hover, the California-based company behind the Hoverboard.
Yes, you can really stand on the thing and yes, it really floats, but there is a bit of a catch:
Our patented technology transmits electromagnetic energy more efficiently than previously possible, enabling platforms to hover over non-ferrous metals with payloads. It is scalable to any size and any weight.
The limitation of needing a non-ferromagnetic metal surface to float over aside, the technology still looks pretty cool.
Amazingly, only a handful of the actual backers will receive a working hoverboard; the ten units have all been snapped up at a buy-in of ten large. The sub-$10,000 tier of funding is for developer kits and short hoverboard rides at Hendo's facility.
The ShopBot Desktop CNC mill can perform a variety of cutting tasks in a variety of materials, all depending on what kind of bit you're using. So when learning to use one, the first physical skill you'll master is how to install and remove a bit in the machine. Whether you've used power tools or not before, it's a pretty simple procedure:
Once you've got a bit installed, you'll need to "zero," or calibrate that bit, so that the machine knows exactly where that bit is in 3D space. Here's how that routine goes:
Sure, it's an advertisement, but if we're going to have goods hawked at us, this is how we'd prefer it be done. To promote their color-shifting Hue LED bulbs, Philips put together this entertaining, too-short video showing how living rooms have evolved, starting in the Boardwalk Empire days and running up until today. While we're presumably meant to focus on the lighting fixtures, the thorough set-dressing will capture your attention:
To be nitpicky, I'd like to have seen a little more Mid-Century Modern, and was it just me or did they seem to skip both the '70s and the '90s altogether?
These are exciting times for those looking to get into digital fabrication, as the technology really is starting to trickle down. With MakerBot the go-to for desktop 3D printing and ShopBot cornering the shop-based prototyping and production market, Inventables reckons there's room for something in-between: A machine it's calling Carvey, designed by Scott Wilson and MNML.
Billed as a "3D carving machine," what Carvey has in common with MakerBot's Replicator line is the fully-enclosed, desktop form factor; these are machines that could be placed in the office portion of a design firm, as opposed to the heavy-duty machines in the modelmaking shop area.
Where it differs from the MakerBot is in what it has in common with the ShopBot line: Carvey is subtractive, not additive. It's essentially a CNC mill, albeit it a miniature one. With a work area of just 12" x 8" and a Z-axis of under three inches, it's no competitor for a ShopBot (whose entry-level Desktop roughly doubles the work area in all axes), but it's not meant to be; while you won't be using Carvey to produce furniture, it's meant to be good enough to produce smaller items like sunglasses, jewelry, small signage, electronics enclosures, et cetera, out of wood, plastic or metal.
We all know the oceans are filled with plastic waste, and we've seen the horrific photos of dead animals that have ingested the stuff. It is up to activists, responsible corporate citizens and lawmakers to stop these plastic garbage patches from growing. But that won't solve the problem of how to get rid of the stuff that's already floating around in there.
Enter Boyan Slat, just 19 years of age. At 6, he was diving in Greece—that country whose postcards show pristine beaches and blue water--and was horrified at the amount of floating garbage he encountered. "I saw more plastic bags," Slat told the BBC, "than fish." When he returned home to the Netherlands, he started working on a way to rid the oceans of garbage—and his design solution is as promising as it is out-of-the-box.
The conventional thinking goes that ships need to be sent out into these garbage patches with huge tow-nets. The problem is that these nets would capture aquatic life as well as the garbage they're trying to collect. And ships burn fuel. So Slat took a closer look at how oceans operate and how the garbage migrates around.
Oceanbound trash tends to gather into their own little garbage continents, driven by "gyres," or rotating currents. There are five of these trash gyres worldwide.
Although the concentration of plastic in these areas is high—it's sometimes described as a plastic soup—it's still spread out over an area twice the size of Texas. What's more, the plastic does not stay in one spot, it rotates. These factors make a clean-up incredibly challenging.
"Most people have this image of an island of trash that you can almost walk on, but that's not what it's like," says Slat. "It stretches for millions of square kilometres - if you went there to try and clean up by ship it would take thousands of years." Not only that, it would be very costly in terms of both money and energy, and fish would be accidentally caught in the nets.
Slat reasoned that it would be more efficient to let the ocean move the trash around, as it does on its own. We would then simply place floating barriers in the known trouble spots, allowing the floating garbage to simply run into the barriers. Aquatic life could still flow under the floating barriers unmolested, with no nets for them to get caught in, and the barriers would be anchored to the seabed via cables to prevent them from floating off. Garbage could then be harvested and recycled from an area with a much smaller footprint.
