    From the Forums – Beaglebone Black SPI with Microchip 25LC512 #beagleboneblack @TXInstruments @beagleboardorg

    BeagleboneBlackData

    “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 #ArtTuesday

    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!)….

    This video is made of 800+ laser engraved frames on a solid block of maple #ArtTuesday

    Here at Adafruit we’re huge fans of laser engraving everything. That’s why we were super impressed by this intricate video from Vimeo user Nando Costa.

    …”The New America” is a short animation in which every frame was created by laser engraving its unique artwork onto a solid block of maple. Once complete, the entire sequence of +800 frames was then photographed and assembled into this motion piece.

    This piece was funded by really kind friends and supporters via Kickstarter. After many unforeseen issues and delays, the entire process took about two years.

    As seen in the video, each frame is unique. Aside from the design of each frame itself being distinct, small variances that naturally occur in the laser engraving process as well as the different wood grain of each frame naturally created subtle shifts of the position of the artwork. An effect that I was particularly interested in and that could naturally be achieved in digital assembly, but that I was much more excited about re-creating with real objects.

    The abstract storyline showcased in this piece is a concoction of a variety of ideas and can perhaps be described as a union between concepts and experiments born during the Situationist movement and real life events experienced during the last few years in American society. Particularly the duality between the economic downturn and the shift in values and beliefs of many citizens.

    FreedomBone: How to turn your BeagleBone Black into a personal communications server #beagleboneblack @TXInstruments @beagleboardorg

    NewImage

    Bob Mottram made this great tutorial on how to turn your BeagleBone Black into a FreedomBox-like personal communications server.

    If you look at it from an engineering perspective, an iterative perspective, it’s clear that you have to try something rather than do nothing.

    – Edward J. Snowden

    Today many of us rely upon “free” services in the cloud, such as Gmail, Facebook, Google+ and so on. It might appear that these services are indispensible infrastructure of the modern internet, but actually they’re not strictly needed and the amount of value which they deliver to the average internet user is very marginal. It is possible to be a citizen of the internet and yet not use those things – to disintermediate the most well known companies and cut out their prurient or merely cringeworthy business models.

    FreedomBone is a personal home communications server based upon the BeagleBone Black hardware. It’s small and cheap and will allow you to use email, have your own web site and do social networking in a federated way without needing to rely upon any intermediary companies other than your ISP.

    You should consider doing this if you are a freedom-oriented sort of person and you want to maintain sovereignty over your information. Laws in many places in the world consider you to have relinquished any property rights over data which you put onto a server not owned by youself (i.e. owned by a third party, such as Google or Facebook).

    If you don’t like the idea of having all your communications intercepted and investigated by the Surveillance State then you should consider running a FreedomBone. If your profession involves maintaining confidentiality as an essential feature, such as legal or medical services, counselling, teaching or any sort of activism then you should consider running a FreedomBone.

    The Beauty of Japan’s Artistic Manhole Covers #ArtTuesday

    NewImage

    Colossal has a bunch of pictures of these incredibly cool looking manhole covers found all over Japan. What a beautiful way to brighten up the streets.

    Japan is a country full of amazing art. Some of it is housed within museums and galleries while others are right underneath our feet. I’m talking, of course, about Japan’s peculiar obsession with manhole covers. Just about anywhere in the country you can find stylized manhole covers, each more beautiful and intricate than the next. For the past several years photographer S. Morita has traveled around Japan photographing artistic manhole covers.

    As to why this phenomenon developed, signs point to a high-ranking bureaucrat in the construction ministry who, in 1985, came up with the idea of allowing municipalities to design their own manhole covers. His objective was to raise awareness for costly sewage projects and make them more palatable for taxpayers.

    Thanks to a few design contests and subsequent publications, the manhole craze took off and municipalities were soon competing with each other to see who could come up with the best designs. According to the Japan Society of Manhole Covers (yes, that’s a thing) today there are almost 6000 artistic manhole covers throughout Japan. And according to their latest findings, the largest single category are trees, followed by landscapes, floral designs and birds – all symbols that could, and surely did, boost local appeal.

    Square Market Accepts Bitcoin #makerbusiness

    Adafruit 2828

    Square Market Accepts Bitcoin.

    Let’s dive into the technical details of checking out. When a buyer opts to “Pay with Bitcoin” we first generate a new Bitcoin address and attach it to the order. We will continually monitor this address throughout the checkout process so we know when it has received payment.

    Next, the buyer submits their payment. Buyers with a mobile Bitcoin wallet, simply open their wallet and scan the QR code to load the transaction details. Those with a hosted Bitcoin wallet receive instructions for entering the required information.

    Once the payment details are loaded into the buyer’s wallet, they submit their payment to the network. Next, we detect that our receiving address was successfully funded and automatically advance the buyer to the order confirmation page. It’s pretty magical to witness first-hand!

    Keeping it simple for the seller, the seller receives the amount of the purchased goods or services in USD and in the amount of USD advertised to the sellers’ customer at the time of transaction, so the seller takes no risk on Bitcoin value fluctuations. The seller then fulfills their customer’s order. Seamless!

    It’s exciting to take another step towards helping sellers reach more customers and making commerce easy for everyone.

    Use This Tutorial To Become a House-Elf

    house elf ears

    In Harry Potter, house-elves like Dobby get the short end of the stick. However, they’re still fun to cosplay and the ensemble can be simple. You really only need ears, a dingy outfit, and a sock to carry around. Instructables user Kiteman put together an easy to follow tutorial on making house-elf ears from felt, a headband, glue, and a template (which is available for download). You could definitely opt to use a material like latex to get closer to the look seen in the films, but you don’t have to be exact. Whatever method works best for you is completely fine.

    Here’s how he reinforced the ears to make them less floppy:

    Depending on the thickness of your felt and the clagginess of your glue, the ears may be floppier than you like.

    I had bought pipe-cleaners, intending to glue them up inside the fokded toos of the ears, but the combination of felt and PVA proved stiff enough for my needs.

    If your ears need reinforcing, trim or fold the the pipe cleaners to the right length to hide inside the top of the ears, and then glue them in place.

    Fluffy pipe-cleaners can be fixed in with most fabric glues, but if you’re using smooth wire, you may need to use hot-glue, or some other slightly more heavy-duty glue.

    Make Your Own Animatronic Cat Ears!

    Animatronic Cat Ears by abetusk

    I saw the demo video for the neurowear “necomimi” brain controlled cat ears and I thought they were pretty awesome. I’m just starting to learn electronics and I thought a fun project to start out would be making my own version. Sadly, I don’t think I’m adept enough yet to take on making my own EEG and I don’t think the EEG’s that are available are very reasonably priced, so I settled for having a button input to control the cat ears.

    I wanted to build something that wasn’t too expensive and was easy enough to be done in a sitting or two. I picked out some cheap servo motors, some craft supplies, spent a weekend or two developing code to control the servo’s from a microcontroller and after much trial and error, I built some kitty ears that I think are pretty decent.

    Modern art from Hubble’s Fine Guidance System?!?

    NewImage

    Sometimes art can be accidental… via European Space Agency.

    A piece of art? A time-lapse photo? A flickering light show?

    At first glance, this image looks nothing like the images that we are used to seeing from Hubble.

    The distinctive splashes of colour must surely be a piece of modern art, or an example of the photographic technique of “light painting”. Or, could they be the trademark tracks of electrically charged particles in a bubble chamber? On a space theme, how about a time-lapse of the paths of orbiting satellites?

    The answer? None of the above. In fact, this is a genuine frame that Hubble relayed back from an observing session.

    Hubble uses a Fine Guidance System (FGS) in order to maintain stability whilst performing observations. A set of gyroscopes measures the attitude of the telescope, which is then corrected by a set of reaction wheels. In order to compensate for gyroscopic drift, the FGS locks onto a fixed point in space, which is referred to as a guide star.

    It is suspected that in this case, Hubble had locked onto a bad guide star, potentially a double star or binary. This caused an error in the tracking system, resulting in this remarkable picture of brightly coloured stellar streaks. The prominent red streaks are from stars in the globular cluster NGC 288. It seems that even when Hubble makes a mistake, it can still kick-start our imagination.

    DEADLINE REMINDER: NEW INC: New Museum’s Art Incubator – Applications Now Open with April 1st Deadline

    NEW INC: New Museum’s Art Incubator Applications Now Open: First Round Due April 1st, 2014. First Round Deadline tomorrow!

    NEW INC, the first museum-led incubator, is a shared workspace and professional development program designed to support creative practitioners working in areas of art, technology, and design. Conceived by the New Museum in 2013, the incubator is a not-for-profit platform that furthers the Museum’s ongoing commitment to new art and new ideas. Launching in summer 2014, NEW INC will provide a collaborative space for a highly selective, interdisciplinary community of one hundred members to investigate new ideas and develop a sustainable practice.

    Creatives today are working in unique ways that are cross-disciplinary, collaborative, leveraging technology, and increasingly straddling the line between culture and commerce. Because they are exploring new modes of cultural production, the professional landscape in which they work is still undefined, and few resources and systems exist to support these enterprises, or to address the unique challenges they are encountering. NEW INC provides a lab-like environment and framework for the development of new ideas, practices, and models in the pursuit of innovation.

    Over the course of a twelve-month residency, members will have access to full-time and part-time coworking desk space, shared resources, events, and professional development programming, as well as a robust network of mentors and advisors that includes members of the New Museum’s staff and affiliates. NEW INC members will also benefit from developing their ideas under the umbrella of the Museum, working in close proximity to Museum artists-in-residence, programs, and affiliates like IDEAS CITY and Rhizome, as well as our anchor tenant, Columbia University Graduate School of Architecture, Planning and Preservation (GSAPP) Studio-X….

    Apply
    We are currently accepting applications for full-time and part-time memberships for the inaugural year of NEW INC, scheduled to kick off in August 2014.

    Deadline: April 1, 2014. Applicants will be reviewed and accepted on a ROLLING BASIS.

    Criteria

    • Membership is only open to emerging professionals not currently enrolled in an academic program who are US citizens or already have a valid visa for conducting business in the US.
    • Individuals and small teams of up to four people are eligible for membership.
    • Full-time memberships require a twelve-month commitment and participation in the professional development program. Part-time memberships are available for shorter terms but are subject to limited access to the space, resources, and programs.
    • Applicants must have a body of work, project, product, or creative enterprise positioned at the intersection of technology, art, and design.
    • A limited number of subsidized desk fellowships will be available for applicants who demonstrate exceptional talent but lack financial means.

    NEW PRODUCT – Adafruit Assembled Pi T-Cobbler Breakout for Raspberry Pi

    1754 LRG

    NEW PRODUCT – Adafruit Assembled Pi T-Cobbler Breakout for Raspberry Pi: Now that you’ve finally got your hands on a Raspberry Pi®, you’re probably itching to make some fun embedded computer projects with it. What you need is an assembled add on prototyping Pi T-Cobbler from Adafruit, which can break out all those tasty power, GPIO, I2C and SPI pins from the 26 pin header onto a solderless breadboard. This mini kit will make “cobbling together” prototypes with the Pi super easy. Designed for Raspberry Pi Model B Revision 1 or Revision 2.

    This assembled Cobbler is in a fancy T-shape, which is not as compact, but is a little easier to read the labels. We also have the more compact original Cobbler.

    The assembled Pi T-Cobbler mini kit comes with a 26 pin ribbon cable, and an already soldered T-Cobbler as shown. No soldering required! This mini kit comes fully assembled!

    NewImage

    The PCB and header come soldered together so you can plug the cable between the Pi computer and the T-Cobbler breakout. The T-Cobbler can plug into any solderless breadboard (or even a prototyping board like the PermaProto). The T-Cobbler PCB has all the pins labeled nicely so you can go forth and build circuits without keeping a pin-out printout at your desk. We think this will make it more fun to expand the Pi and build custom circuitry with it.

    The Adafruit Pi T-Cobbler is compatible with both versions 1 and 2 of the Raspberry Pi Computer – for version 2 computers, note that the GPIO #21 has been replaced with GPIO #27 and that the I2C pins are now I2C port #1 instead of #0. All other pins are the same.

    NewImage

    Please note, this product only contains a 26 pin ribbon cable, a custom PCB with ribbon cable socket and header pins soldered to it. The Raspberry Pi, breadboard, breadboarding wires, cables, components, case, power supply, etc is not included! We do stock many of those items in the shop, so check those out as well!

    What is the Raspberry Pi® ? A low-cost ARM GNU/Linux box.
    The Raspberry Pi® is a single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of stimulating the teaching of basic computer science in schools. The design is based on a Broadcom BCM2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 256 megabytes of RAM.

    An engineering company is creating a robot army inspired by nature #robotics

    PolicyMic has the story on Festo’s incredible nature inspired robots. You can see more animated gifs over at their site.

    German engineering firm Festo is creating a robot army. Sounds scary, right? But there’s no need to fear a “Skynet”-type apocalypse quite yet, because these robots want to do good by making laborious tasks easier in the factories of the future. And they’re using nature as their inspiration.

    Festo summarizes the motivation behind their research on their website: “Gripping, moving, controlling and measuring – nature performs all of these tasks instinctively, easily and efficiently. What could be more logical than to examine these natural phenomena and learn from them?”

    It makes a lot of sense. Why reinvent the wheel when nature has already spent epochs perfecting the mechanics needed for survival on the Earth? This practice of bio-mimicry is widespread in other fields such as molecular biology, where many drugs are designed by optimizing already existing natural products from microorganisms.

    What’s really brilliant about this body of research is that while many of the designs have obvious practical applications, many others have been made in the creative spirit of learning, with some wild results.

    Lycopodium powder “dances” on subwoofer in this incredibly cool video #MusicMonday

    Geek.com posted about this awesome video featuring lycopodium powder on top of a subwoofer.

    Sometimes the simplest of elements can be combined to create the most interesting of results. And I’m not talking about the old baking soda-plus-vinegar volcano, this is the combination of nothing more than an active subwoofer cone and a dust-like powder. The two were all it took to create this incredibly cool video, though the addition of a Red Epic camera certainly helped.

    The video, entitled The Essence of Sound, features lycopodium powder dancing around on top of a subwoofer. Lycopodium is better known as flash powder, as in the stuff that was used in the pyrotechnic explosions that lit old-timey photographs. It’s still used to in laboratory settings, for instance when it’s necessary to make sound waves visible (as we see here). Basically, lycopodium is the best way possible to make a fireball on a budget, but it’s also quite handy for other things as well.

    Below the powder is a subwoofer doing exactly what subwoofers do. As the subwoofer bounces the powder hypnotically moves creating the incredible forms we see. The patterns aren’t quite as regular as one would expect, so it’s likely that there is more too the situation than just a speaker with some dust on it, but that’s essentially what we’re looking at.
