3D Printing with Liquid Metals at Room Temperature: One Small Step for Terminators

We’ve seen a 3D printer make objects out of soft materials, and one that uses titanium powder.  This 3D printer made by researchers at North Carolina State University is somewhere in between: it uses a liquid metal alloy that is stable at room temperature.

3d printing liquid metals by dr michael dickey et al

According to the university’s press release, Dr. Michael Dickey, Colin Ladd, Ju-Hee Soand John Muth were able to make freestanding structures out of an alloy of gallium and indium. At room temperature, the alloy reacts with oxygen in the air, forming “a ‘skin’ that allows the liquid metal structures to retain their shapes.” Watch the video below, but I must warn you: it will make you want to play Sims.

According to the researchers, the printer can not only stack metallic beads together as shown in the video; it can also inject the alloy into a polymer template to assume a specific shape. The template can be dissolved to free the printed metal structure. The alloy is also conductive, meaning it can be used to connect electronics. I wonder if the alloy can be used with carbomorph to print complex gadgets.

Pink X-Wing Fighter in the Forest: Because.

Hey look. It’s a pink X-Wing in the forest? What gives? Did Ewoks get a hold of a truckload full of Pepto Bismol and assault this fighter with it? That sounds like those mischievous bastards. They love a good joke/vandalizing stuff. Did Endor have a pride parade? Nope.

This “natural X-wing” was made by Guillaume Renou for an exhibition in France that celebrates nature. Bizarre right?

If teenage girls fought for the rebellion, this is what their ships would look like – along with a fuzzy Hello Kitty plush hanging in the cockpit of course. And this guy would be their leader:

What else can you say about such a pink ship? Sure is pink. Damned Ewoks!

Camp Grounded is Digital Detox for Adults

When a night out involves bringing two smartphones, a music player, a 7-inch tablet, and a 10-inch tablet, then you know you’ve got a problem. Most people are addicted to tech these days, and it ruins more social events than you think.

This reality is what prompted Digital Detox to come up with a camp offering for adults addicted to their gadgets called Camp Grounded.

Camp Grounded

It’s a three-day camp where the usage of digital devices isn’t allowed at all. It’s described as a gathering “where grown-ups go to unplug, getaway [sic] and be kids again.” Typical camping activities are scheduled throughout the weekend, from bonfires and sing-alongs to capture the flag and archery.

Camp Grounded1

Other activities include writing sessions and creative workshops. Digital Detox held the first Camp Grounded this past June, where each slot cost $350(USD). You’ll be surprised to know that all slots sold out. No word on timing for the next Camp Grounded session, but you can get on their email notification list here.

Squito Throwable Ball Camera: Squito! You Shoot Me!

A wild spherical camera appears! Actually it’s not the first of its kind that we’ve seen, but unlike the previous device, Serveball’s Squito is being designed for both professional and recreational use. Forget about Instagram or Vine, the cool kids will want to get ball shots! Yeah! No.

According to Serveball’s press release, the current prototype of Squito has three cameras, an inertial measurement unit, a microcontroller and an image processor. As you’ll see in the video below, the prototype can take 360º panoramic pictures and videos. When taking pictures, the Squito can reorient and stitch the images that its cameras take. When shooting a video, the Squito can stabilize the video, but don’t expect a free falling camera to be as steady as one on a tripod. The Squito will also be able to wirelessly send its pictures and videos to PCs and mobile devices.

The tail end of the video featured a version of the Squito with night vision and thermal imaging capabilities. From what I can tell those features will be on a separate variant of the Squito, which Serveball is calling the Darkball. Fold your browser into a ball and throw it to Serveball’s website for more on its cameras.

Hyrel 3D Printer Can Print with Play-Doh

3D printing continues to evolve, with printers improving in precision, speed and cost efficiency. While some high end machines can print in materials ranging from plastic to metal and even ceramic, this is the first time I’ve heard of a 3D printer that can output soft and squishy materials, like clay.

The Hyrel 3D printer offers the ability to swap out their regular PLA/ABS plastic filament extruder with a special unit which can extrude soft materials. The printer can be loaded with air-dry modeling clay, Play-Doh, Plasticine, Silicone or even Sugru, a durable, self-setting and flexible rubber compound that’s good for fixing and hacking all kinds of stuff. Here’s some footage of the Hyrel outputting Sugru and then some Play-Doh:

I’m not exactly sure why you’d want to sculpt 3D objects in Play-Doh, since it’s not designed to harden, but clay or Sugru could produce some interesting results for sure. And for Play-Doh fans, it sure beats a Fuzzy Pumper Barber Shop.

Powered Jacket MK3 Exoskeleton: Metal Gear Alpha

Your teenage child is too big – and cool – for the Kid’s Walker, but you don’t trust her with the Kuratas mech just yet. How are you going to retain your title of World’s Greatest Parent? Simple. With Sagawa Electronics’ Powered Jacket MK3 walking exoskeleton.

There’s only one problem: like the Kuratas, the Powered Jacket is either a promotional tool or an insanely expensive commercial product.

powered jacket mk3 exoskeleton by sagawa electronics

Allegedly, the exoskeleton is over 7ft. tall and weighs a mere 55lb. as it is primarily made of carbon fiber and aluminum. Its arms are controlled simply by moving the corresponding lever, while its legs are strapped to the wearer’s own legs. Apparently its fingers can also be controlled precisely. It also has a transparent canopy to protect the wearer against pedophiles. Now watch its demo video:

That was the best video I’ve in seen my entire life. Science fiction, comedy, drama and horror all in one. You can doubt the extent of Sagawa Electronics’ contribution to robotics, but its contribution to humor is the stuff of legends. As claimed in the video, Sagawa Electronics will supposedly make only five Powered Jacket MK3 units for the foreseeable future, with each one priced at ¥12,500,000 (~$124,000 USD). If that’s how much is needed for them to make another video, then folks I’m telling you that’s a freakin’ bargain.

Shape-It-Up Lets You Tweak 3D Shapes Using Simple Hand Gestures: Pottery Simulator

The researchers behind Shape-It-Up call it a “Hand Gesture Based Creative Expression of 3D Shapes Using Intelligent Generalized Cylinders”, but it’s totally a pottery simulator. Decades from now, if – when? – Paramount Pictures decides to remake Ghost, the characters will be using Shape-It-Up while a dubstep remix of Unchained Melody plays in the background. Oh, my WUB WUB WUB WUUUUUB…

shape it up 3d shape system by vinayak et al

Shape-It-Up is a project by Purdue University Engineering students Vinayak, Sundar Murugappan, HaiRong Liu and Karthik Ramanilets. It lets users manipulate a virtual cylinder by using simple hand gestures, which are tracked using a Kinect. Skip to around 1:28 in the video below to see it in action.

I guess you could say that was… righteous. YEEEEA- I’m old. The researchers think of Shape-It-Up as a way for designers to start their sketches in an easier and more intuitive manner, not as a way to create a polished model. But if you pair it with a 3D printer, I think it can also be used as a way to teach kids about the basics of CAD and 3D printing. Now get off my lawn and head to Purdue University’s website for the project’s abstract.

SpaceX Grasshopper Reusable Rocket Knows How to Park in Reverse

We’ve already invented a (partially) reusable spacecraft. But the rockets that were used to boost NASA’s space shuttles – and other spacecraft in general – were all designed for one-time use only. That makes space travel wasteful and expensive. That’s why the space transport company SpaceX is working on creating reusable rockets.

spacex grasshopper reusable rocket test

Like other rockets, the SpaceX Grasshopper takes off vertically. But instead of returning to Earth as a thousand molten bits when its work is done, the Grasshopper gracefully lands vertically, like a gymnast with a flaming butt. Have you seen one of those? They’re amazing. The video below shows it rising up to a height of 1,066 ft. before landing smoothly on the same launchpad that it came from. SpaceX claims that, thanks to its advanced navigation sensors, it was “directly controlling the vehicle based on new sensor readings, adding a new level of accuracy in sensing the distance between Grasshopper and the ground, enabling a more precise landing.”

Either that or they just played the first half of the video in reverse. Then again, the geniuses at SpaceX literally specialize in rocket science, so uh, rocket science… isn’t rocket science for them. I think I broke an idiom. Anyway, let’s just believe in them and egg them on so that one day a SpaceX rocket can teach me how to parallel park.

‘Like to Death’ Online Art Project Disappears When You ‘Like’ It

When you ‘like’ something on Facebook, it stays on your feed longer and sometimes appears on the news feeds of other people in your network. By ‘liking’ something, you make it stay visible for a longer period of time as it circulates on social networks.

The “Like to Death” online art project, on the other hand, works oppositely. Instead of staying visible longer, the piece disappears instead.

Like to Death1

Like to Death is a collaboration for Adidas Originals by digital artist Geoffrey Lillemon and Stooki, an independent UK-based brand that also happens to be an art collective. The project’s site greets visitors with the following message: “Social media is the fifth dimension that fabricates our online existence. Imagine a life without it, if you can’t you have been possessed. Break the curse, like it to death.”

That statement has a point, but to some people, not being on social media would make them feel like they didn’t exist anymore in real life.

As more people like the interactive work, the ominous figure is slowly engulfed in flames. When it hits 20,000 likes, it’s supposed to disappear. You can check it out for yourself here.

‘Bridge of Life’ Reminds People Life Gets Better to Prevent Suicides

When something particularly bad or painful happens, some people just withdraw and never come out of their cocoons. They can recover slowly or they can get worse and one day decide that they want nothing more than to end it all.

So many of the latter go to the Mapo Bridge in South Korea to do just that. Between the years 2007 and 2012, more than a hundred people jumped from the bridge in attempts to end their lives. They might not have gotten the help they needed previously, but you can at least convince them otherwise at the last minute. That’s what the Seoul City government is trying to do in collaboration with Samsung Life Insurance.

bridge of life 1

Instead of constructing high fences or a suicide barrier on the bridge, they added interactive handrails that address passersby directly. They’re embedded with motion sensors to detect the presence of anyone near them, so when someone passes by, the handrail lights up with an inspiring quote or message that were written with the help of psychologists and suicide prevention specialists.

Bridge of Life1

A sample message is as follows: “How have you been? Have you eaten? If you need to talk, why don’t you talk to us?” This is then followed by a number for a suicide hotline.

Since launching the project, the Seoul City government claims suicide rates from the Mapo Bridge have dropped 77%. This potential lifesaver is just ingenious, and while it won’t solve the underlying problems of potential jumpers, it could convince them to get the help they need before taking their lives.
