    Xenomorph Made From Everyday Household Objects

    xenomorph costume

    Though it’s great to be able to work with materials such as Worbla and metal, you can use everyday items to build incredible costumes. This xenomorph from Alien, for example, was built fom a variety of objects Peter Kokis tracked down here and there. He spent 450 hours cobbling bits and pieces together into this super impressive alien. What did he use? Here are some of the Xenomorph’s parts:

    12 plungers, 10 knife sharpeners, silicone wine glass drain mats(?), lots of coat hooks, 12 pull handles, 2 Halloween decorations, Army boots, toy sword, knee guards, 10 costume ball masks (for their elongated noses), 2 pr. hockey leg guards, hockey helmet, ski goggle lense, football shoulder pads, baseball pants, 45 velcro straps, shinguards, headband, 48 coiled sneaker laces, athletic cup, teeth from a werewolf mask, bottlecap opener, 2 exercise weights, work gloves, lots of ribbed plastic tubing in various diameters, lots of vitamin bottlecaps, and lots and lots of plastic from trashcan bodies & lids…recurring shapes used throughout his body for a consistent effect.

    Artist Ei Wada uses outmoded technologies to create art pieces #ArtTuesday

    In Ei Wada’s latest piece, Toki Ori Ori Nasu – Falling Records, watch as tape reels release tape to the bottom of glass columns and then play music as the tape is reversed. via Gizmodo

    Japanese artist Ei Wada, who was born in 1987, belongs to a generation that spent middle school feverishly poring over cassettes to make mix tapes—until, of course, they were quickly outmoded by CDs, and then MP3s. Now, Ei makes art using the outmoded technologies he grew up with.

    At the Media Arts Festival, the young artist premiered a piece called Toki Ori Ori Nasu—Falling Records: An arrangement of four tall glass columns crowned by tape reels, each slowly leaking black tape that piles up at the bottom of each case, creating almost geological patterns. When the reels are empty, they reverse—and the music they each contain starts to play.

    Editing Circuits With Focused Ion Beams

    CPLD

    [Andrew] has been busy running a class on hardware reverse engineering this semester, and figured a great end for the class would be something extraordinarily challenging and amazingly powerful. To that end, he’s editing CPLDs in circuit, drilling down to metal layers of a CPLD and probing the signals inside. It’s the ground work for reverse engineering just about every piece of silicon ever made, and a great look into what major research labs and three-letter agencies can actually do.

    The chip [Andrew] chose was a Xilinx XC2C32A, a cheap but still modern CPLD. The first step to probing the signals was decapsulating the chip from its plastic prison and finding some interesting signals on the die. After working out a reasonable functional diagram for the chip, he decided to burrow into one of the lines on the ZIA, the bus between the macrocells, GPIO pins, and function blocks.

    Actually probing one of these signals first involved milling through 900 nm of silicon nitride to get to a metal layer and one of the signal lines. This hole was then filled with platinum and a large 20 μm square was laid down for a probe needle. It took a few tries, but [Andrew] was able to write a simple ‘blink a LED’ code for the chip and view the s square wave from this test point. not much, but that’s the first step to reverse engineering the crypto on a custom ASIC, reading some undocumented configuration bits, and basically doing anything you want with silicon.

    This isn’t the sort of thing anyone could ever do in their home lab. It’s much more than just having an electron microscope on hand; [Andrew] easily used a few million dollars worth of tools to probe the insides of this chip. Still, it’s a very cool look into what the big boys can do with the right equipment.

    Line Segments Space – Kimchi and Chips

    An architectural web of threads subtends a null space. It hangs abstract and undefined, a set of thin positive elements segmenting the dark negative space between. Dynamic imaginary forms are articulated into the physical volume by the material of this thread, and the semi-material of the light. The visual gravity of the filaments occupying the space between.

    A 2D canvas is reduced from a surface piece into a line segment, but then constructed into another dimension, a volume. Light creates contrast and order on the lines to articulate digital matter. Digital forms inhabit the interconnected boundaries of space, becoming incarnate as visual mass.

    The artists reference Picasso’s light painting, and Reticuláreas of Gego who’s work offers a contemplation of the material and immaterial, time and space, origin and encounter and art and technology.

    Wu-Tang Rapper GZA Delivers TED Talk About Science Education #makereducation

    Rapper GZA of Wu-Tang Clan promotes science education in this awesome TED Talk, from Time.

    “Why is the sky blue? Why is the grass green?”

    The Wu-Tang Clan’s GZA, a.k.a “The Genius,” a.k.a. Gary Grice just gave a TEDxTeen Talk as the latest viral address in his campaign “to provide a model for students to communicate the information learned from their science teachers.”

    As Wu-Tang’s dozen or so active members are busy finishing the iconically absurdist rap group’s 20th anniversary reunion album, it just so happens that GZA is also leading Science Genius, an “urban science initiative” that he cofounded with Rap Genius and Christopher Emdin of Columbia University’s Teachers College. The project weaves lyricism and artistic conception into the science curricula of 10 public New York City high school classrooms.

    While many musical artists are known to promote public funding of arts education, GZA and his bandmates have long been obsessed with the many mind-blowing phenomena of the universe. “Why is the sky blue? Why is the grass green?” he asks. “Why is metal a conductor of electricity, and wood is not; but you’re more likely to be struck by lightning when standing under a tree?”

    “These are questions that require science to answer.”

    Can we design machines to automate ethics?

    Adafruit 2831
    Can we design machines to automate ethics? by Tom Chatfield @ Aeon.

    For the French philosopher Paul Virilio, technological development is inextricable from the idea of the accident. As he put it, each accident is ‘an inverted miracle… When you invent the ship, you also invent the shipwreck; when you invent the plane, you also invent the plane crash; and when you invent electricity, you invent electrocution.’ Accidents mark the spots where anticipation met reality and came off worse. Yet each is also a spark of secular revelation: an opportunity to exceed the past, to make tomorrow’s worst better than today’s, and on occasion to promise ‘never again’.

    High Voltage Image Making by Phillip Stearns.

    A project exploring the use of electrical discharge as a means of creating images in photographic media. High Voltage Image Making is a developing body of work that started with the Retinal Pigment Epithelium and Other Vision Technologies, Real or Otherwise Imagined and has grown to include Polaroid Type 55 @ 15KV. The project explores and extends the expressive capacity of instant photographic film technology beyond its ability to capture images of the world through the application of high voltage and various chemical agents. These treatments approach the film technology as a recording media, capable of creating images from physical, electrical, and chemical transformations. The project takes its cues from artists such as Man Ray (photogram), Pierre Cordier (chemigram), Marco Breuer (scratched expose and developed c-prints), Chris McCaw (sunburned prints) and Hiroshi Sugimoto (static discharges on photopaper).

    Students Create A Motor Control Shield For Self Balancing Robots #beagleboneblack @TXInstruments @beagleboardorg

    NewImage

    Students from UC San Diego create a motor control shield for Beaglebone Black. via Make

    A group of students from The University of California, San Diego created a motor control shield for the BeagleBone Black. The shield can be used in projects like self-balancing vehicles (as shown in the video above), drones, or robots. Amy Szeto from Texas Instruments was demoing the board on the floor of International CES 2014 along with a few other maker-friendly products.

    “When WowWee approached the lab we looked at a number of different things we could do with them. One of the things that came up was what is now MiP. I took lead on the development of the first prototype, which was Arduino-based. I did all the programming, the electrical and the design work. This was about a year and a half ago. I then have been working with WowWee on the production model, teaching them how balancing works, helping them get all the right components together, making sure it has good balancing performance with the low cost toy-grade components and that the toy hits a great price point.

    Once we were working towards getting the production version’s details together, my professor wanted to start on the educational side of things. With all the work that was done on MiP, we had a much better understanding of what needed to be done to make a small Segway-like vehicle that hit a low price point. So my professor, Thomas Bewley, one other PhD student, Nick Morozovsky, and I started work on the first educational MiP called MyMiP. Much of what I had done for MiP went into MyMip. And we ended up successfully teaching the first hands on controls course based around MiP.

    Some time later after the completion of the course, we began to look at what we wanted to do for next year’s course. It was at this time that we made the decision to pursue the BeagleBone Black as I had taken Arduino to its limits to do MiP. We wanted students to be able to do more after the class then just get a mobile inverted pendulum balancing. We wanted them to be able to start adding some level of autonomy. For this new project, James Strawson, a new PhD in lab at the time, took lead. James went ahead and took the educational MiP to the next level resulting in BeagleMip.”

    E-Waste Quadcopter Lifts Your Spirits While Keeping Costs Down

    quad-overall

    The advancement of Quadcopters and their capabilities over the last few years has been amazing. Unfortunately, the price point to get into the sport with a decent size, non-toy, vehicle is still several hundred dollars. And what’s the fun with buying one when you can built it?!? Strapped for cash and feeling the same way, [Hans] over at the hackerspace Knackatory decided to build a quadcopter from e-waste.

    The + shaped frame is made from lightweight plywood. It’s pretty obvious that the main rotors are PC Fans, 140mm in this case. Normally, these wouldn’t be able to create enough lift to get out of their own way except the on-board 24v Dewalt cordless tool battery bumps up the fan speed to 15,000 rpm. The one orange fan allows the operator to maintain a visual reference to which side of the ‘copter is forward.

    An Arduino running MultiWii control software is the brains of this UAV. The MultiWii software uses the sensors from part of a Nintendo Wii remote to sense orientation and movement. While there is no hand held transmitter with this quadcopter per se, communication to the host computer is handled by a wireless router running OpenWRT. The router is the gateway that allows the Arduino and Ethernet Shield combination to communicate through the Hackerspace’s wifi network. Flight plans are pre-programmed. Admittedly, the real time control through computer keyboard commands needs a little work. The team plans on interfacing a regular USB game controller with the software.

    Making stuff out of e-waste is a great way to recycle. Remember this e-waste 3D Printer?

    The beauty of macro butterfly wings by linden gledhill

    biochemist and photographer linden gledhill has captured a mesmerizing series of images which study the structure of butterfly and moth wings. using various levels of magnification, the macro shots zoom in on what is an incredible and kaleidoscopic visual: the intricacy and delicacy of insects’ wings. specimens of varying species and physical characteristics are collected, documented and later photographed using an automated macro focusing rail. forming an iridescent quilt, the scales layer in depth, volume and chroma, shimmering and glittering in a multidimensional composition. at the range of enlargement gledhill shoots the images at, they are near impossible to recognize as the physical characteristics of the flying species, but instead transform into dazzling perspectives on a part of the natural world.

    If You Let Them Build It, They Will Learn: An ode to and inside look at library makerspaces #makereducation

    Screen Shot 2014 03 24 at 1 30 54 PM

    In this piece, Laura Fleming at worldsoflearning.com, covers the historical and practical side of the modern library makerspace. She emphasizes their importance for both students and educators and provides some tips on how to create create a makerspace of your own.

    It is my belief that every child has the right invent, tinker, create, innovate, make and do. This belief is what drove my mission to establish a makerspace here at New Milford High School. I am very proud of the fact that our makerspace transcends academic potential, social barriers and even language and development. Students of all levels can take full advantage of the resources and activities in this space. I often see students taking it upon themselves to help their peers and to inspire their peers to experiment, make and do. Our space sometimes is filled with our engineering and conceptual physics students, but also our english language learners and special needs students. We truly have democratized the tools and skills necessary to design and make things that were of interest to our students while, at the same time, exposing them all to a new world of possibilities. My makerspace is learner-driven and exploits the idea of experiential learning. It is a mash-up of differentiated learning experiences combining traditional elements and new technologies…

    …The layout of our makerspace consists of ‘fixed’ stations and ‘flexible’ stations. The fixed stations are areas that are out in our makerspace all of the time for students to just walk in and sit down at and engage with. These include our littleBits bar, our Take-Apart Tech Station (or ‘breaker space’), our Lego table, our Makey-Makey station, and our 3-d Design and Printing station. The impetus behind choosing these to be our fixed stations was that I wanted to include activities that students would be able to start and complete during their limited time in the space as well as have them be able to do so independently, with little instruction on my part. This informal learning piece has been key in students wanting to visit the space and engage with the activities here on their free time…

    …All good teachers today have to acknowledge that they are also learners, and setting up a maker space in your library is a great way to ensure that you, the teacher, cannot only learn new things from the space but to do so openly with your students, to let them see you and respect you as a learner just like them!

    Stretch Bike Hauls All

    cargobike

    Need to haul some stuff? Got nothing to haul it with? Then fashion yourself a cargo bicycle! We’ve seen cargo bikes before, but none quite like this one. Built from a German “klapprad”, [Morgan] and his father fashioned a well constructed cargo bicycle which is sure to come in handy for many years.

    They started by cutting the bike in half and welding in a 1 meter long square tubing extension. The klapprad style bicycle is made from thick metal stock, making it sturdy and easy to weld. This process also make it a true “stretch” vehicle as opposed to one that replaces the front end in order to keep the handle bar assembly near the rider.

    Along with some nicely done woodwork and carbon fiber, they used parts from an old mountain bike including a front fork, front bearing and handlebar, tubing from an old steel lamp, a kickstand from a postman motorcycle, and a kitchen sink to complete the build. It should handle well so long as the weight of the cargo is not heavier than the weight of the driver.

    “Maddox” on the Adfruit Forums shared Beaglebone Black SPI with Microchip 25LC512:

    As a learning experience, I got a little microchip flash chip (25LC512) working with my BBB. I thought the steps I went through and performance observed could be useful to others, so I wrote a blog post about the details here with links to the git repo for code and performance traces from my Saleae logic analyzer (wonderful tool).

    Synopsis:

    SPI through libsoc library can issue commands every ~100 usec (observed between 77 and 125 usec). Random 1 byte reads can complete every ~100 usec as well. 128 bytes can be transferred from the BBB to/from the 25LC512 in ~200 usec. A long block of sequential reads run at about 640 KB/s….

    Artist and Light Engineer Jim Campbell’s Sculptural LED Light Installations

    Jim Campbell’s Sculptural LED Light Installations:

    Artist Jim Campbell details the inspiration and custom electronics behind his new series of light installations currently on display at Bryce Wolkowitz Gallery in New York City. The exhibition ranges from LED panels that project ultra low-resolution Kodachrome home movies, to topographic LED sculptures created from transparent, molded resin.

    From The Creators Project:

    Even the Lumiére Brothers would glow over the work of artist and light engineer, Jim Campbell. The prolific pioneer of patchwork bulb-wiring’s career spans three decades, and his work keeps on getting better—the artist’s newest works have been called “consummate” and “transformative” by Art Daily after their debut this month at Bryce Wolkowitz Gallery. It goes without saying that the mastery of his specific genre of low resolution re-imagings, communicated through programmed bulbs and LEDs, is a practice thirty years in the making.  

    Good thing he’s got a retrospective show coming up. Rhythms of Perception, the artist’s first major exhibition in a New York museum, brings a survey spanning his career in contemporary art to the Museum of the Moving Image on March 20, from his earliest pieces to his project in Madison Square Park and his new work, showcased in our documentary on the luminary (above!)….
