    Alien Chestburster Costume


    alien chestburster

    If you’re not up for creating a full on Xenomorph costume, go smaller and make a Chestburster. Instructables user Fiery She-Beast made one from wood, foil, and clay. On top of that you’ll need an old t-shirt you’re okay with ruining and fake blood and a few other essentials. She’s how she made the little baby alien:

    Stuff the pipe with tin foil, creating a lump on top of the pipe, this forms the alien’s head shape. Squash a few lumps of clay onto to pipe, and begin to sculpt the alien. It has a large forehead with no eyes, make the facial area smooth. The mouth has no apparent lips, but it has lots of sharp teeth, so be sure in include those. The temples in jaw consist of random lines and patterns with one main line running from the bottom of the jaw and curving upward on both sides. The tail is wrapped around the alien at the base of where is busted out. I found it fun to make a few intestines and flesh lumps around it from where it came out.

    Mentalfabrications LANDSCAPES

    Artist Ion Popian’s Mental Fabrications Project Transforms Brainwaves into Physical Forms:

    ION POPIAN – Mental Fabrications Exhibit Brief

    Technology has long since adapted our bodies to the world. Voyager-Challenger Deep-impact suits, these have all extended our purview higher, deeper, and guarded us against the destructive forces we bring upon ourselves. Mental Fabrications proposes a technological intervention focused on our own depths in order to extend our mental not physical facilities. It proposes a human-machine relationship, a pairing that isolates our unconscious from our entirely too human subjective filter. Where a pencil extends our intellectual world through the stylized articulations of our hands, this project explores the potential for architecture and urbanism to develop by giving our unconscious lives an unmediated chance to be formative in the design process. Before we are human we are something else. Base pairs making up our DNA strands combine according to non-human attraction infinitely reorienting in relation to one another to create diversity. A computer code modeled after these processes can exceed its computational potential becoming generative in its own right. Creating a forum where this peculiar human-nonhuman relationship can flourish opens the way to design that is responsive, living, and can contribute to the world it inhabits.

    An Exceptional BASIC Computer

    BASIC

    Since [Dan] has started using microcontrollers, he’s been absolutely fascinated by the fact these chips are essentially low performance computers. Once he caught wind of TinyBASIC, he decided he would have a go at creating a simple, tiny computer that’s very simple to the old, tiny, 8-bit computers of yore.

    The computer is built on an Arduino shield, using TinyBASIC, the TVout library, and the PS/2 keyboard library. After piecing together a little bit of code, the Arduino IDE alerted [Dan] to the fact the TVout and PS/2 libraries were incompatible with each other. This inspired [Dan] to use the ATMega328P as a coprocessor running the TVout library, and using the capacious ATMega1284P as the home of TinyBASIC and the PS/2 library.

    A circuit was put together in Fritzing using minimal components, and a PCB milled out of copper board. After the board was tinned, [Dan] had a beautiful minimalist retro computer with nearly 14kB of RAM free and an RCA display.

    Future versions of the build will probably be based around the Arduino Mega, allowing for a TV resolution of 720×480. Also on tap are an SD card slot, LEDs, pots, and possibly even headers for I2C and SPI.

    Multi-materials, Noise-canceling 3D-printed Chaise Longue by Neri Oxman #3DxArchitecture #3DThursday #3DPrinting



    Multi-materials, Noise-canceling 3D-printed chaise longue by Neri Oxman. From Dezeen:

    This chaise longue by architect, designer and MIT professor Neri Oxman features 44 different composite materials 3D-printed inside a wooden enclosure, creating a multi-coloured recliner.

    …Each of the materials has a different rigidity and colour, and is arranged to cushion the user. The choice of shapes is also informed by their noise-cancelling properties.

    “The chaise is designed to use curved surfaces that tend to reflect the sound inwards,” said Oxman. “The surface structure scatters the sound and reflects it into the 3D-printed skin that absorbs that sound, and creates a quiet and calm environment.”

    The outer layer is made from a solid wood shell milled using a CNC machine by New York company SITU Fabrication. It follows the contours of the body, with a deep seat, back rest, and a curving head piece that immerses the user and helps block out sound.

    Gemini Alpha was designed in collaboration with W. Craig Carter, professor at MIT’s Department of Materials Science and Engineering.

    It is currently on display at Le Laboratoire art and design centre in Paris and the second piece, Gemini Beta, will be unveiled in September.

    3D Materials Inspiration – Fish3d: A New Touch-sensitive, Interactive Modeling Environment #3DThursday


    Pasted Image 4 10 14 2 56 AM

    3D Materials Inspiration – Fish3d: A New Touch-sensitive, Interactive Modeling Environment. From SolidSmack.com:

    If you’ve been fishing, you know the layer of slime that covers the fish, protecting it from your nasty hand bacteria. It’s also a defense mechanism that helps protect the fish from predators and, as it turns out, is much more than what it seems. Particularly in the case of the Hagfish. Researches at MIT’s Media Ecology Lab have discovered a new way to interact with our Hagfish friends via the slime they produce while at the same time developing parametric surface geometry, a development that could very well push product design into your surrounding and away from the desktop.

    A small amount of slime is first scraped from the body of an anesthetized Hagfish. Added to distilled water, the tightly bundled cells unravel, immediately binding the threads together to form large amounts of viscous material. This material is highly formable where the addition of electric current manipulates the substance to form on, around, or against items, even to the level of separate ‘parts’ being created, color added or opaqueness adjusted through simple touch/gestural interaction. The slime threads are the key. Dr. Fudge (real name) of the Comparative Biomaterials Lab states:

    The slime is composed of fine protein slime threads as well as a mucus component that comes packaged in tiny vesicles. When these components are ejected from the slime glands, they combine synergistically to form a slime mass in which a large volume of water is entrained. Recent work by Julia Herr has investigated the chemical composition of the slime and the mechanisms of mucin vesicle stabilization a deployment. Tim Winegard recently published a paper on the mechanisms of thread skin deployment, which involves the unravelling of 15 cm long threads from subcellular structures…

    These “slime threads” are similar to spider silk in their dimensions, but they differ in a couple of important ways that make them excellent candidates for such a biomimetic project. Slime threads are built within cells from intermediate filament proteins via a process of hierarchical self-assembly. This is quite different from the dynamic spinning process that transforms liquid crystalline spider silk proteins in the silk gland into an insoluble fibre.

    These slime threads have even more potential for an interactive 3d modeling experience when they are still attached to the creature. Apparently, the Hagfish itself can be used as somewhat of an input device, directing viscosity of the materials, attach points and even patterned geometry….

    EU Iniative to 3D Print Food for the Elderly by 2015 #3DxKitchen #3DThursday #3DPrinting


    Pasted Image 4 10 14 3 13 AM

    EU Iniative to 3D Print Food for the Elderly by 2015. From Horizon:

    Researchers are working to revolutionise mealtimes for elderly people with swallowing problems – by 3D-printing their food.

    The 3D printer will be able to create easily digestible food, which not only maintains the shape and taste of the real thing, but can also be fortified with specific nutrients.

    Studies suggest that more than one in five people over the age of 50 have problems swallowing their food – a condition known as dysphagia. Those with this problem have difficulties eating because the larynx fails to close properly during swallowing, so that food ends up in the lungs instead of the stomach.

    …Kück expects that elderly residents will be able to choose from different menus each week and the meals will be prepared in a processing plant before delivery. It is hoped that the new technology will also mean that food can be personalised, adding specific vitamins or nutrients – for example folic acid – as required by residents.

    …The 3D printer will work in the same way as a conventional inkjet device – except the cartridges are filled with liquefied food, instead of ink.

    ‘If you have people who don’t want vegetables, you might fortify the meat with certain vitamins – there really are no restrictions in terms of what food can be recreated.’

    See what your Arduino is thinking with MicroView

    Microview

    As some of you have already noticed on our social channels, we are thrilled to announce a new partner in the Arduino at Heart Program: MicroView, the first chip-sized Arduino compatible that lets you see what your Arduino is thinking using an OLED display.

    Microview, by Geek Ammo, is versatile as it meets the needs of beginners and experts alike.

    For beginners the MicroView is the first Arduino to ship with built in tutorials. Beyond the tutorials, the MicroView’s OLED display helps to visualize what the microcontroller is doing. You can print print debug messages straight to the OLED display without needing to connect to the Arduino IDE. The immediacy of being able to see live sensor values makes the whole experience so much easier.

    microview_anim

    A rich library saves experts time by allowing them to quickly display Strings, Counters, Gauges, Sliders, and Bitmaps with only a couple of lines of Arduino code.

    Marcus Schappi, Geek Ammo CEO, told us:

    “We’re proud that MicroView has been accepted to be part of the Arduino at Heart Program. By basing the MicroView on the architecture of the Arduino Uno, we’re standing on the shoulders of giants. We can’t wait to see what people make with the MicroView.”

    Arduino At Heart

    Their Kickstarter campaign is really going well, but the campaign only has a few days left, so get in quick and back the MicroView now so you don’t miss out!

    Resetting DRM On 3D Printer Filament

    eeprom

    The Da Vinci 3D printer is, without a doubt, the future of printing plastic objects at home. It’s small, looks good on a desk, is fairly cheap, and most importantly for printer manufacturers, uses chipped filament cartridges that can’t be refilled.

    [Oliver] over at Voltivo was trying to test their new printer filament with a Da Vinci and ran head-on into this problem of chipped filament. Digging around inside the filament cartridge, he found a measly 300 grams of filament and a small PCB with a Microchip 11LC010 EEPROM. This one kilobyte EEPROM contains all the data about what’s in the filament cartridge, including the length of filament remaining.

    After dumping the EEPROM with an Arduino and looking at the hex file, [Oliver] discovered the amount of filament remaining was held in a single two-byte value. Resetting this value to 0xFFFF restores the filament counter to its virgin state, allowing him to refill the filament. A good thing, too; the cartridge filament is about twice as expensive as what we would normally buy.

    3D Design (Counter) Inspiration: 15 Hilariously Bad Designs for Everyday Objects #3DThursday


    Pasted Image 4 10 14 2 40 AM

    3D Design (Counter) Inspiration: 15 Hilariously Bad Designs for Everyday Objects, via WIRED:

    How can an object be incredibly, exquisitely, perfectly designed–and a colossal pain in the ass to use?

    That’s precisely what Katerina Kamprani shows us with “The Uncomfortable,” a collection of familiar household objects rendered aggravatingly unusable with a few simple adjustments. The ranks include open-toed rain boots, a pitcher that pours back into itself, and a button as thick as thumb.

    Kamprani, a designer and architect in Athens, creates the objects with 3D rendering software. Her first stubborn creation was a closet with doors that opened inward.

    The conceit is clever enough on its own, but Kamprani’s poetic execution is what makes the project so great. Each object stays largely faithful to the materials and forms of the original; typically there’s just one deft change that sends its utility flying out the window.

    Kamprani starts by recreating the steps it takes to use an object, isolating a single interaction to sabotage. She consults with friends and draws sketches, auditioning a variety of tweaks and transformations until she’s found just the right one. “I know an idea is good when it is so ridiculous I even surprise myself,” she says….

    Ultimaker Pitches in 3D Printers to Help Zuyd University Compete in Shell Eco-marathon with 3D Printed Car (VIDEO) #3DThursday #3DPrinting



    Ultimaker Pitches in 3D Printers to Help Zuyd University Compete in Shell Eco-marathon with 3D Printed Car:

    Geldermalsen, the Netherlands, 9 April 2014 – Zuyd University of Applied Sciences is participating in the 2014 Shell Eco-marathon with a car for which 3D printing technology has been used in the production process. The Shell Eco-marathon is an annual competition that aims to challenge student teams to develop, build and test ultra-efficient cars.

    Zuyd University is participating for the fifth time, but it is the first time that 3D printing technology is being used during the production process. A desktop 3D printer makes car parts like the dashboard, steering wheel, mirrors and handles. On top of that, 220 molds are printed to make the carbon fibre parts for the body of the car.

    Ultimaker supports the Zuyd University team with ten Ultimaker Original 3D printers to make the printing as fast and efficient as possible.

    “The main goal is to make a car that is as sustainable as possible, and the energy consumption must be as low as possible,“ says Professor Rob van Loevezijn of Zuyd University’s Faculty of Beta Sciences and Technology. 3D printing has been chosen because this technology is budget and environmentally friendly. The PLA plastics used in the 3D printer are environmentally friendly and biodegradable. Making the molds with a 3D printer is also a lot faster than making the traditional wooden molds….

    Hot Wax Pen EggBot Accessory – Electro-Kistka from Evil Mad Scientist #3DThursday #eggbot


    Electro Kistka

    Hot Wax Pen EggBot Accessory – Electro-Kistka from Evil Mad Scientist:

    The Electro-Kistka for EggBot is a compact kistka — a hot wax dispensing pen — designed to work with the EggBot. With it, you can use the traditional wax-resist and dye (batik) method to produce stunning colorful eggs in the same fashion as Ukranian pysanky eggs.

    In the example shown here, we first “paint” the wax logo on a bare (white) egg, and then dye the egg red and allow it to dry. We then paint additional wax onto the egg (the words “Electro-Kistka”), and finally dye the egg black and allow it to dry again. Then, after melting away the surface wax, we reveal the design: a black background, with red and white areas.

    Repeated application with care can produce more detailed designs, with additional color layers.

    (These intense red and black colors are from our batik egg dyes.)

    This kit contains the complete Electro-Kistka attachment for EggBot and basic accessories that you need to get started. It comes assembled, tested, and ready to install on your EggBot. It is compatible with both The Original Eggbot (white chassis) and Ostrich Eggbot.

    Enginursday: The Hormes Robot Platform

    For those of you who have been living under a rock and weren’t aware, we really love robots around here. Flying robots, cute robots, ingeniously engineered robots and generally chill robots are always guaranteed to catch our eye. With this year’s AVC quickly approaching (and with it being National Robotics Week), I wanted to do a shout-out to an awesome customer project with a wickedly tough-looking robot.

    Hormes Robot

    Meet the Hormes Robot

    The Hormes robot was created by Charles and Richard Raitt, who have both participated numerous times in the FIRST robotics competition. Both brothers bring their area of expertise to the robot design process, with Richard working on the mechanical design and Charles working with the electrical systems. Beside the joy of just having a beastly, 56-pound robot, they decided that they wanted something where they “can hand the controls to someone at a Maker Faire and not worry about it getting broken. No promises about anyone’s shins though…”

    The original idea was drafted up in SketchUp before they began building.

    SketchUp Robot Draft

    A mid-project picture of the working drawing

    With the design mostly worked out, it was material gathering time. Most of the chassis was bought from brick and mortar hardware stores. A stock 1/8" steel plate was cut and drilled on a press to create custom corner brackets. However, the ½-inch trade conduit (which is actually 5/8-inch ID) used in the roll frame was actually gathered as scrap practice bends from a local vocational school. This brings up a great point - where do you collect scrap materials for your projects? Let us know in the comments!

    Detailed T Joint

    T Joint showing the frame connections

    Richard then counterbored the steel axle slug inside the joints to accept an Allen bolt. A 2-inch long slug of the steel axle holds the front and back sections of the rollcage together, and barbed “tube connector nuts” hold the crossbar on and the rollcage to the frame. Richard also coped the crossbar ends to create a friction fit. This design is solid enough to even support Richard standing on it!

    One of my favorite features of this robot is the use of the dual-sprocket on the gearbox shaft to drive the wheels. Not only is it a slick-looking design, but this design also allows a higher clearance on the robot. The interwheel space is clear of chains, allowing Hormes to tackle larger obstacles.

    Dual Sprocket Chain Connection

    Snazzy dual sprocket connection for the #35 roller chain

    After getting the chassis together, the first integration of the electronics with the mechanical build came together beautifully, just in time for Christmas. This was the first functioning version of the robot, though it wasn’t weather-proof or safe from the mud (no one wants their robot’s insides looking like this after a test drive).

    First Iteration of Hormes

    First iteration of the Hormes robot

    Two TALON SR motor controllers drive the two CIM brushed DC motors. The system is powered off of a sealed lead acid battery at 12V, 10Ah, running through a power distribution board. Each motor connects to its own 30A auto resetting breaker.

    The brains of the Hormes are actually surprisingly simple. Charles used an Arduino Uno R3, a USB Host Shield, a PC USB Xbox360 wireless controller, and a SEEED Studio Protoshield. The proto shield has two red indicator LEDs on it. An XBox360 wireless controller functions as the driving remote. You can check out the code on the Arduino here.

    Interior of Control Box

    Interior of Control Box

    A heavy duty tool box functions as the housing for the control system, protecting the electronics from the elements and creating a solid mounting system. Not pictured above is the USB Xbox receiver, as it had broken.

    While the robot itself is fantastic, I also appreciate the origin of the name. According to the brothers, “Hormes” is the Greek spirit of “putting oneself into action.” Being no strangers to the project cycle, Richard says “I’ve started so many projects, and I swear I am going to finish this one.” Perhaps my naming convention for projects has been my problem with finishing them all…

    The Raitt brothers showed off Hormes at the FRC NASA/VCU Regional event in Richmond recently. They also plan to attend the Hampton Roads Mini Maker Faire in October. You can also find out more information about their robot here. We wish them the best of luck with the Hormes robot, and hope this has inspired you AVC contenders with some additional robot ideas!

    An Emulated Commodore 64 Operating System for the Raspberry Pi

    Commodore-PI

     

    It’s no secret that Commodore users love their old machines with the Commodore C64 being chief among them with 27 Million units sold worldwide. Speaking as a former Commodore Business Machines (CBM) engineer the real surprise for us is the ongoing interest and devotion to an era typified by lumbering 8 bit machines and a color palette consisting of 16 colors. Come to think about it, that’s the description of Minecraft!

    Jump forward to today and it’s a generation later. We find that the number of working units is diminishing as age and the laws of entropy and physics take their toll.

    Enter the Commodore Pi, an emulated Commodore 64 operating system for the Raspberry Pi. The goals of the project include an HDMI and composite compatible video output, SID based sound, Sprites and other notable Commodore features. They also plan to have hooks for more modern technology to include Ethernet, GPIO and expansion RAM.

    A video demo of the emulator can be found below. If you’re just warming up to the Commodore world, you’ll definitely want to know the real story behind the C128.

    Thanks to [Terry Fisher], head of PCB development at Commodore Business Machines for the lead.

    Turning An Analog Scope Into A Logic Analyzer

    scope

    When [Marco] was planning on a storage oscilloscope build, he realized having a small device to display eight digital signals on an analog scope would be extremely useful. This just happens to be the exact description of a simple logic analyzer and managed to turn his idea into a neat little project (German, Google translation).

    The theory of operation for this surprisingly simple, and something that could be completed in a few hours with a reasonably well stocked hackerspace or parts drawer in a few hours. A clock generator and binary counter are fed into the lower three bits of a simple R2R DAC, while the 8 inputs are fed into an 8-input multiplexer and sent to the last bit of the DAC. With nothing connected to the logic analyzer inputs, the output to the scope would just be an 8-step ramp that would appear as eight horizontal lines on the screen. With something connected to the logic analyzer input, an extremely primitive but still very useful logic analyzer appears on the screen.

    While it’s not the greatest analyzer, it is something that can be cobbled together in an hour or two, and the capabilities are more than sufficient to debug a few simple circuits or figure out some timings in a project.
