Drones Rearrange This Canopy Prototype So You're Always in the Shade

When they're not rebuilding the environment or exploring Mars, the drones of the future may help us avoid some of life's minor inconveniences. A group of masters students at the University of Stuttgart envisioned a fleet of drones that does just that for their thesis project: As New Atlas reports, the drones are part of a roaming canopy, responding to sunlight above and movement below to ensure you're always in the shade.

Without the drones, the prototype, dubbed Cyber Physical Macro Material, resembles a normal stationary structure. Tall black poles support panels that fit together magnetically, protecting whoever's beneath them from the sun's rays. But this design is only effective when the sun is in a certain part of the sky: As the day progresses, the canopy's shadow shifts, and people are forced to move with it if they want to stay out of the light.

But these panels don't stay in the same spot for long. They come equipped with special sensors that keep track of the orientation of the sun and a communications system that corresponds with autonomous drones nearby. If a panel is no longer keeping the ground beneath it shady, a drone will glide over, lift it up, and snap it into a different part of the canopy like a puzzle piece. Drones can also rearrange the panels in response to the size and location of the crowd beneath them, which means the same structure that shades a few pedestrians can also keep a larger party cool.

There are legal and logistical hurdles the project would need to overcome before becoming a system in a real-world, but the researchers behind it say that for now it's meant to get people thinking about the potential applications for drones. A press release from the university reads, "With its ability to continuously reconstruct during use, the system challenges pre-conceived ideas of robotic digital fabrication and sophisticated pre-fabrication for architecture."

BioLite Has Designed a Headlamp That Won't Irritate or Slip Off Your Head

Headlamps are convenient in theory. Instead of fumbling with a flashlight or your phone in the dark, you can strap one to your head and walk your dog, do some late-night grilling, or venture around your campsite hands-free.

But in reality, the awkward design—with a bulky light that digs into your skin and slides down your forehead—cancels out much of the product's appeal. Luckily, it doesn't have to be this way, as the folks at BioLite have demonstrated with their reinvented headlamp.

The BioLite HeadLamp 330, which debuted on Kickstarter in 2018 and is now available on Amazon, promises to make you forget you're even wearing it. Inspired by modern wearables, BioLite has retooled various elements of the clunky traditional design to make it as comfortable as it is functional.

The ultra-thin light sits flat against your skull, which means you won't have any painful marks in the middle of your forehead when you take it off. The band itself is made from a moisture-wicking fabric that feels good on your skin, even when you're working up a sweat. And unlike conventional headlamps, BioLite has redistributed the power source to the back of the head in its design, balancing the weight and taking care of any slippage issues.

As is the case with other BioLite products, technology is an essential part of the design. The 330-lumen lamp projects light up to nearly 250 feet in front of you. There are variable lighting settings, too: You can opt for either a white spot or floodlight, both with dimming options, or a strobe light feature; there's also a red floodlight. It can run for three and a half hours at maximum brightness or 40 hours at minimum brightness, and when it needs to be recharged, you can just plug it into a micro-USB source like a solar panel or powerbank.

Get your own BioLite Headlamp for $49 on Amazon. It's available in in ember red, ocean teal, sunrise yellow, or midnight gray.

Bioengineering Student Is Building Custom Prosthetic Arms From LEGO Bricks

The custom LEGO designs built by 19-year-old David Aguilar aren't meant to sit on a shelf. For years he's been ignoring the instructions that come with LEGO sets to make functioning prosthetic arms for himself, and now he's sharing his creations online, Reuters reports.

Aguilar—who lives in Andorra, a small principality on the French-Spanish border—was born with a rare genetic condition that left him without a right forearm. He built his first artificial limb out of LEGO bricks at age 9, and hasn't looked back. Today Aguilar is pursuing an eduction in bioengineering at the Universitat Internacional de Catalunya in Spain, and he's already on LEGO prosthetic No. 4.

After acquiring complex LEGO sets for things like airplanes and construction vehicles, Aguilar reconfigures them into arms and adds electric motors that allow him to move his fingers and bend his elbow. He documents his building process on YouTube under the name Hand Solo. Each arm he builds is named MK followed by the model number (MK I, MK II, etc.), a nod to the MK suits built by Tony Stark in the Iron Man series.

The LEGO prosthetics are more than conversation starters—they're also affordable compared to professionally made robotic limbs on the market. Aguilar tells Reuters his dream is to one day provide cheaper options to prosthetics-wearers like him.
