    The Drone That Will Change Graffiti: Motherboard Interviews KATSU #arttuesday



    Check out Motherboard‘s interview with artist KATSU, who’s using drone technology to power his latest graffiti-art endeavors. He also plans to develop the quadcopter as open source technology!

    His new project is not fake or hypothetical, though it does elevate his work to new heights. He has developed a system to attach a spray can to a quadcopter, creating the world’s first true graffiti drone. The drone is capable of spraying canvases or walls hundreds of feet high, granting the artist access to physical spaces that were previously inaccessible. At the Silicon Valley Contemporary art fair, which opens April 10, KATSU will show a series of canvasses that were created with his graffiti drone. The drone is capable of spraying canvases or walls hundreds of feet high, granting the artist access to physical spaces that were previously inaccessible. The video above, produced with The Hole NYC, his gallery, shows the drone in action.

    Motherboard: What are you actually going to do with the drone?

    KATSU: A lot of my work comes out of demonstrating and experimenting with different technologies for creative use. Basically, drones have lowered in cost enough that they are attainable, so I got my hands on some DJI Phantom 2s, and I have been experimenting with the idea of using drones to accomplish the same things that drones are beginning to be used for in broader society, but in this case for crime, vandalism, art. I really want to look into the way that a person and a drone could connect. I thought, ‘I could go out into the city and spray paint using a drone wherever I wanted to, in basically unreachable spots and in unusable areas.’

    I also had a desire to make a series of paintings that would begin to express what happens when technology begins to collaborate in artistic creation and disruption. I started to collaborate with some developers and hardware people that I’m friends with, and we started working with Arduinos and 3-D printing, and basically raced to create this prototype remote sprayer that works with a drone. I attached a cradle with a spray paint can and other hardware to the drone. I created a series of paintings that are larger, about maybe 3 feet by 3 feet all the way up to 25 feet by 15 feet. Those served as this arena for experimentation, where I was testing out the system. And basically, I achieved the perfect air pressure, the perfect weight of the paint and the perfect materials so that the drone didn’t freak out when I attached these mechanisms to it.

    Open-source technology is central to the drone hobbyist culture. Was that part of the allure for you, given your extensive background in creating open-source products?

    I’ve never been interested in creating works to hold tightly and keep ownership of. I just have an uncontainable excitement for seeing magic happen in front of me, and I think that there’s nothing that I want more than to see people either react to this or find flaws in it or find ways to just really blow this concept up. It’s just sheer excitement about the possibilities.

    Retrotechtacular: The Cryotron Computer

    04WBuckNewPhotoHand-1395161077806

    Have you ever heard of a Cryotron Computer before? Of course not. Silicon killed the radio star: this is a story of competing technologies back in the day. The hand above holds the two competitors, the bulkiest one is obviously the vacuum tube, and the three-legged device is what became a household name. But to the right of that tube is another technological marvel that can also be combined into computing machines: the cryotron.

    [Dudley Allen Buck] and his contributions to early computing are a tale of the possible alternate universe that could have been cryotrons instead of silicon transistors. Early on we find that the theory points to exotic superconductive materials, but we were delighted to find that in the conception and testing stages [Buck] was hacking. He made his first experimental electronic switches using dissimilar metals and dunking them in liquid helium. The devices were copper wire wrapped around a tantalum wire. The tantalum is the circuit path, the copper wire acts as the switch via a magnetic field that alters the resistance of the tantalum.

    The name comes from the low temperature bath necessary to make the switches work properly. Miniaturization was the key as it always is; the example above is a relatively small example of the wire-wound version of the Cryotron, but the end goal was a process very familiar to us today. [Buck] was searching for the thin film fabrication techniques that would let him shoe horn 75,000 or more into one single computing platform. Guess who came knocking on his door during this period of his career? The NSA. The story gets even more interesting from there, but lest we rewrite the article we leave you with this: the technology may beat out silicon in the end. Currently it’s one of the cool kids on the block for those companies racing to the quantum computing finish line.

    Can math equations be a form of art? #ArtTuesday



    Laughing Squid posted this interesting video from DNews.

    DNews host Tara Long examines whether math equations can be a form of art. Specifically, Long discusses a recent scientific paper that explored whether mathematicians experience “beautiful” equations in much the same way as others do art.

    Many have written of the experience of mathematical beauty as being comparable to that derived from the greatest art. This makes it interesting to learn whether the experience of beauty derived from such a highly intellectual and abstract source as mathematics correlates with activity in the same part of the emotional brain as that derived from more sensory, perceptually based, sources.

    NSTA 2014: Bialik Delivers, Spicer Dances and Dow’s Robot Shows No Shame #makereducation


    Packed Keynote at NSTA14 Day 1 1024x764

    Check out It’s About Time’s re-cap of NSTA (National Science Teachers Assocation Conference ) 2014:

    An estimated 11,000 educators and exhibitors converged in Boston this year for the National Science Teachers Assocation Conference (#NSTA14), and if you’re an enthusiastic lover of all things STEM, it was as if the mother ship had called you home.

    As Joshua Manley (one of our ever-insightful science educator bloggers) put it so eloquently in his pre-conference blog post (“10 Must-See Sessions at NSTA 2014”), this year’s jam-packed agenda with over 1,500 sessions and events left us feeling like kids in an ice cream store (so much to see and taste, so little time!).

    NSTA-goers who descended the escalators onto the exhibitor floor were immediately greeted by Camp IT’S ABOUT TIME® – per usual, we claimed one of the best parking spots (er, booths) at the conference, attracting teachers galore with our innovative products, knowledgeable staff and giant-sized No. 2 pencil, an unexpected crowd-pleaser while we also had the pleasure of hearing the many wonderful stories of science teachers engaging young minds in new and exciting ways. As our our tagline says: “Full STEM ahead!”

    We also hosted 12 “Future of Education” workshops featuring exciting presentations by the likes of Dr. Arthur Eisenkraft, Professor of Science Education at the University of Massachusetts and one of “IT’S ABOUT TIME ®’s Top 10 Game-Changing Edupreneurs to Watch in 2014.” (View the full list HERE.)

    Meanwhile, our team was pretty much everywhere, sweeping the labyrinthian Boston Conference Center to capture images, tweets (#NSTA14) and video from last week’s events (including video interviews with several NSTA featured speakers Arthur Eisenkraft, Yvonne Spicer, John Penick, and Steve Rich which will be posted on our YouTube channel shortly HERE)….

    Automated Bed Leveling For 3D Printers Is Now Solved

    bed

    The latest and greatest feature for 3D printers – besides being closed source, having no meaningful technical specs, and being on track towards pulling in $10 Million on a Kickstarter – is automated bed leveling. This amazingly useful feature makes sure your prints have proper adhesion to the bed, reduce print errors, and put even inexpensive printers into the realm of extremely expensive professional machines. Automated bed leveling has been extremely hard to implement in the past, but now [Scottbee] has it figured out with a working prototype on his Makerbot Replicator 2X.

    Earlier attempts at automated bed leveling used some sort of probe on the tool head to measure the build plate, calculate its flatness and orientation in space, and compensate for any tilt in software. [Scottbee]‘s solution to the problem took a different tack: instead of trying to compensate for any odd orientation of the build surface in software, he’s simply making the bed level with a series of springs and cam locks.

    [Scottbee]‘s device levitates the build plate on three springs, and replaces the jack screws with three “gimballing pins” and pin locks. With the pin locks disengaged, the bed plate is pressed down with the printer’s nozzle. By moving the extruder across the build plate and locking the pins in place one by one, [Scottbee]‘s device defines the plane of the build plate along three points. This makes the build platform parallel to the extruder nozzle, and also has a nice benefit of setting the distance from the build platform to the nozzle precisely with incredible repeatability.

    The mechanics of locking the three gimballing pins in place  only requires a single DC gear motor, driven by an extra fan output on the Makerbot’s electronics. It’s simple, and with a bit of rework, it looks like most of the device could also be 3D printed.

    An awful lot of RepRaps and 3D printers out there already use three points to attach the build plate to a frame. With a little bit of effort, this same technique could be ported and made a bit more generic than the Makerbot-based build seen above. It’s amazingly simple, and we can’t wait to see this applied to a normal RepRap.

    Thanks [Josh] for the tip.

    Shell Shorts: A concise history of the Eames Shell Chair and how they are made today #ArtTuesday #manufacturing


    NewImage

    Herman Miller has a great write up on the history of the iconic Eames Shell Chair as well as some fun animated gifs on how they are made today. Check out the full story here.

    Below is some history of the chair written by Amber Bravo.

    The story of the Eames Plastic Shell Chair really began more than ten years prior to Charles and Ray’s 1950 debut of their now iconic design for Herman Miller. Understanding this decade-long evolution not only helps shed light on Charles’ oft-quoted—“The details are not the details. They make the design”—it says a lot about the responsibility Herman Miller and the Eames Office and family have assumed at Charles and Ray’s request, to stay true to the designers’ tireless drive to improve and refine their designs.

    The Eameses were notoriously material agnostic, and the seeds of the plastic shell we know and love today were really planted in the late ’30s, when Charles and Eero Saarinen first began exploring plywood seating in curved forms at Cranbrook Academy of Art, where Charles served as the head of the design department. Saarinen’s father, Eliel, was the head of Cranbrook and Eero was a junior partner at his father’s architecture office. It is likely that both Eames and Eero were influenced by the work of Finnish architect Alvar Aalto, who’d lectured at Cranbrook in the early ’30s and was well known for his bent plywood furniture. Eames and Saarinen’s first attempt at shaping plywood was realized in a chair concept for Eliel’s design for the Kleinhans Music Hall in Buffalo, NY, in 1939. While that chair had two-dimensional curves, their next design, an entry for The Museum of Modern Art’s “Organic Design” competition in 1940 had three-dimensional curves. For this they won first prize, but it was only produced in very limited numbers and not anywhere near to their desired quality. By this time, Charles had met and married Ray Kaiser, a student at Cranbrook, and the two moved to Venice, California to open their eponymous office. Eero abandoned the project, but Charles and Ray were determined to figure out a completely new process for molding plywood into compound curves.

    Charles and Ray continued to experiment with their new technique for molding plywood, and their efforts yielded stretchers, lightweight, stackable leg splints (1942), and a glider seat (1943) for the U.S. Navy. When the war ended, they returned to the concept of a mass-produced chair. Despite their best efforts, they were still unable to produce a single-shell plywood form, but instead landed on a compelling alternative: a chair comprised of separate molded plywood panels for the back and seat, which would become the Eames Molded Plywood Chair (1946), which is still in production today and was subsequently named “Best Design of the Century” by Time magazine. Two years later, they produced a single form shell chair made out of stamped metal for Museum of Modern Art’s “International Competition for Low-Cost Furniture Design.” It took second place in the competition, but the, neoprene-coated prototype was too costly to produce, so Charles and Ray began looking into new materials like plastic reinforced with fiberglass, a material that could be molded into organic shapes and produced cost effectively, but had not yet been used in a consumer application before.

    It was this iteration—released in 1950—that went on to become the first mass-produced plastic chair, but it was not the end of the design’s evolution. Through the years, color and height options, shock mounts, base variations, and choices of upholstery have redoubled, making the chair not only easily reproducible but also highly customizable. Manufacturing processes have also been closely monitored and modified, and, in the late 1980s, almost a decade after Charles’ death in 1978, the environmental implications of fiberglass production were called into question by Ray and Herman Miller. In the early 1990s, Herman Miller ceased production. After years exploring more sustainable solutions, the company reintroduced the Molded Plastic Shell Chair in 100% recyclable polypropylene in 2004, based on prototypes in the Eames Office archives, which Charles and Ray had made with fiberglass-free plastic in the 1970. In 2013, again working with the Eames Family, Herman Miller realized Charles and Ray’s vision for the shell chair design in a new and quite appropriate material—molded wood, thanks to advancements in the 3D veneer technology, and this year, the company has reintroduced the Shell Chair in a sustainably reformulated, Greenguard Gold Certified molded fiberglass as well as in upholstery.

    Taking off where the Eames left off with their 1970 film, “The Fiberglass Chairs: Something of How They Get the Way They Are” WHY revisits the fiberglass production process in our fiberglass manufacturing facility in Ashtabula, OH and in Herman Miller’s own Greenhouse facilities in Zeeland, MI, in ten bite-sized videos, which we’ll be releasing over the course of two days on Instagram (along with some corresponding gif trailers below) and exploring the ways in which Herman Miller is honoring the Eames original design and ethos by pushing the manufacturing process and quality to be the best and most sustainable it can possibly be.

    Becoming Lady Skeletor


    lady skeletor costume

    Skeletor is He-Man’s archenemy. He has a frightening countenance that comes through even in cosplayer’s Constantine In Tokyo’s femme adaptation of the outfit. She designed the armor using Worbla and craft foam, sometimes using the foam as template to cut Worbla. It’s clear an impressive amount of work and creativity went into building this detailed costume. Here’s how she handled creating the crossbones on the armor’s breast plate:

    - Skeletor has a pair of crossbones strapped across his chest. For my Lady Skeletor, I decided to attached the crossbones directly to the armor breast plate and forgo the straps – I don’t feel like it’s a design element that would translate well onto a (relatively) curvy lady! For my belt, I cut out a base belt from craft foam, then cut out the raised edges, glued those details onto the craft foam base, THEN covered the whole thing with ONE layer of Worbla. The process I used for creating the crossbones is identical to this. NOTE: If I had more time, I would have sculpted the crossbones out of clay, let it dry, and then attached it to the breast plate to give them even more dimension. I had 36 hours left at this point and not enough time to make that happen.

    - I drew my desired crossbone shape onto paper, then transferred it onto craft foam. Basically, I wanted a circular base, then the cross bones, then a circular ring to set the gem into. So, there are several layers of craft foam here.

    A Clever New Chemistry Kit Your Kid Will Actually Want to Use #makereducation


    Chem set

    Bioengineer Manu Prakash is an innovator in STEM education. Earlier this year, we celebrated Prakash’s debut of his awesome paper microscope. Now, along with his graduate student George Korir, he has won first prize in the the Science, Play and Research Kit (SPARK) Competition with the development a hand-crank chemistry set for kids, from Wired.

    Prakash hopes to kindle some of the same curiosity about chemistry (minus the actual combustion) with a new hand-crank operated chemistry set for kids. A prototype of the device just won the $50,000 first prize in a contest for inspiring science toys sponsored by the Gordon and Betty Moore Foundation and the Society for Science & the Public…

    The chemistry kit developed by Prakash and graduate student George Korir manages to be both cutting edge and retro at the same time. It uses microfluidic channels like those found in modern DNA chips and other molecular biology equipment to move chemicals around and mix them together. But it also uses punch cards like the ones used in 1950s era computers to control the experiments.

    As you turn the hand crank, the punch card moves through the device, and the pattern of holes punched in the paper controls which chemicals mix with which, and when. Small chips with tiny fluid reservoirs can house up to 15 different chemicals. These could either be pre-loaded or filled by a teacher or parent with an eyedropper. “It’s purely mechanical,” Prakash said. “There’s no electronics, no battery.”
