Earthquakes reinterpreted by the human body become art

via Arduino Blog

simograph0

“Earth Partitions” installation by artist Melik Ohanian was exhibited at the Centre d’Art Contemporain à Sète in France and it’s composed by two synchronized videos with a dancer and a seismogram, the second being “written” by the first.

The dancer with two controllers in the hands was asked to “translate” into corporal expression and movements what he saw in a seismogram of an earthquake . His movements were consequently “translated back” to a seismogram using a device. Both the mime and the seismograph were filmed at the same time and both were then broadcasted simultaneously on two different screens during the exhibition.

sismograph

The project was made thanks to the work of Out of Pluto, a multidisciplinary startup working on the research and development of new technologies to materialize various projects and ideas and decided to share with us some more info about this installation.

sismmicro

Arthur and Mathias, founders of the startup, submitted the project to this blog describing me how they used two Arduino boards:

The Arduino Micro reads the accelerometer values, computes a global value and sends it via bluetooth to the computer. The computer reads this value, computes an angle according to a configurable ratio (sensitivity) and sends a new value to the Arduino Uno. The Arduino Uno sends the angle to the servo motor that rotates to this angle and then come back to 0 (if no other value is sent). Coming back to 0 simulates the end of the “earthquake”. The mechanical part of the arm is flexible so there is some inertia involved, creating the typical outline of seismograms. There is a simple motor to pull the paper at a constant speed.

Take a look at the video:

Art Showcase: A Knight’s Peril

via Raspberry Pi

Rachel here! I love castles. I really love castles. When I was in primary school I would do projects about castles in my spare time – just for fun. I would make wooden swords and reenact battles with my best friend too – Anyway – This week we came across a fantastic application of Raspberry Pi to make a National Trust medieval castle come alive undead. I’ll hand you over to the National Trust and Splash and Ripple, the creative agency behind the work, who explain more about what they’re doing.

Medieval castle haunted using technology with a twist

With its world-first adventure experience “A Knight’s Peril’, Bodiam Castle in East Sussex is quietly revolutionising what people expect from a day out at a National Trust property.

When a company that describes itself as ‘Architects of Extraordinary Adventures’ claims to have revolutionised history interpretation through haunting a 14th century castle, you would expect some kind of technical wizardry to be centre stage. It would be easy to assume they’ve come up with another smartphone app or gamified tablet experience.

england-bodiam-castle_102885-1920x1200

Intriguingly however, they have chosen an opposite track. Splash & Ripple have taken Arthur C Clarke’s declaration that “any sufficiently advanced technology is indistinguishable from magic” as a guiding principal in creating their latest adventure.

The result is digital heritage interpretation turned on its head. They’ve taken the magical abilities of pioneering technology and housed them in the theatrical disguise of a beautifully crafted ‘Echo Horn’.

3 Horns8

The extra ‘magic’ of an Echo Horn actually creates a more convincing experience, in a medieval castle, than a distracting tablet app or audio guide ever could. It intuitively fits the feel of the beautiful 14th century Bodiam castle as you cross its moat and gaze at its stony ramparts, listening to the echoes you’ve caught with it. The beautiful sounds create a deeply evocative group experience, which enhances rather than distracts from the experience of being in the castle.

Visitors carry the Echo Horn with them around the castle in an interactive audio investigation. They must use it to listen in on medieval conversations trapped in the castle walls in order to identify and stop a murderer before it’s too late.

It’s effectively a choose-your-own adventure radio play where visitors’ actions, defined by who they follow and who they accuse, affect the ending of their story. This encourages an active exploration of the historical content, which requires visitors to think about what life was like, rather than passively accept an authoritative interpretation.

New historical research on the castle, which informed the creation of the script, was done in partnership with University of West of England History department.

The experience is being specially showcased at Bodiam castle by the creative team on 4th Dec. It has been a year in the making, and is now available to the castle’s 180,000 yearly visitors for at least the next 12 months.

3 Horns7

Players use an ancient map to navigate the castle, searching for seals that have emerged from the castle walls. These seals contain hidden RFID chips. Each echo horn contains a Raspberry Pi, a Mini Rig and RFID reader.

Rachel again: thanks guys! We love it – I’m looking at organising an office awayday so we can play with the horns ourselves.

 

 

Parkinson’s disease body illusion

via Raspberry Pi

Transports is an interactive installation from Analogue, a theatre/art group, sponsored by the Wellcome Trust, which creates the illusion that the viewer is experiencing Parkinson’s symptoms. As in the rubber hand illusion, the mind is tricked into believing that the user’s hand is the hand shown in some point-of-view video; while a glove with motors makes them feel the tremors associated with the disease.

The whole setup is controlled by a Raspberry Pi. The installation takes the user through a number of everyday tasks from the perspective of Andrew, a man in his thirties with Parkinson’s, who is about to give a speech at a friend’s wedding. Andrew’s experience is informed by a body of first-person data that Analogue collected from the blogs of people dealing with Parkinson’s, and interviews with patients.

This installation isn’t being exhibited as public art at the moment; instead, it’s being used to raise awareness and promote empathy among health professionals and carers. Psychology students are also using it; and there are plans to refine the whole thing by using Oculus Rift or a similar VR headset, and by shrinking the apparatus on the glove.

You can read more about Transports at Analogue’s site, or at the New Scientist.

WiFi-controlled pottery kiln

via Raspberry Pi

I’ve always fantasised about having a kiln in the garage (Eben wants a pick and place machine; we need another garage). Kilns, though, are expensive. And where do you start if you want to refurbish a broken or old one safely?

James Gao has an answer, and it’s got a Raspberry Pi in it. (Well, not in it, but attached very firmly to it.

kiln

James’s girlfriend is an enthusiastic potter, and James is an equally enthusiastic hacker. They came together and made beautiful music a kiln. The project is based around an old electric kiln, which James built holes into to convert it into a propane-fired updraft kiln. A Raspberry Pi is hooked up to a thermocouple and a stepper motor that controls the propane regulator. James 3d-printed gears and a clamp to operate the regulator/motor setup.

stepperpropane

Stepper motor and propane regulator

The kiln operates via a PID, which controls the temperature taking closed-loop feedback from the thermocouple to the regulator. Adjustments can be made remotely; the kiln controller system has WiFi. James has a really interesting series of photographs, with explanatory text and some examples of test firings, over at imgur; he also answers questions about the project at Reddit.

Results of two test firings

Results of two test firings – the variously floppy things are pyrometric cones, used to measure temperature in different parts of the kiln.

There are so many reasons I love this project. It’s a wonderful demonstration of what can be done with no specialised experience (James had never worked with kilns before starting this project, and neither he nor his girlfriend had any knowledge about firing pottery). The ingenuity on show is just brilliant (3d-printed gears!), the pottery that comes out of the end is immensely satisfying – and face it; there’s something very thrilling about flames. On top of all this, the whole project came in at less than $200.

All James’s control software, along with a BOM, is open-source, and available on GitHub.

MoMa welcomes Arduino

via Arduino Blog

Arduino10k

We are really happy to share with you that at the beginning of the week Paola Antonelli (Senior Curator Department of Architecture and Design) and Michelle Millar Fisher, (Curatorial Assistant, Department of Architecture and Design) published on the Moma blog a post announcing the acquisition of Arduino  and other DIY electronic devices in the collection of the  Museum of Modern Art of New York City, with this explanation:

As design curators, we have an instinctive response to designs we find compelling, and when that feeling survives the passing of time, we know we’re on to something worthwhile. We believe our new acquisitions will withstand that test. All promise to make a difference—not just in the utopian “design can save the world” kind of way (always good, but often a high bar for any one object), but at the very micro level. We all know what it feels like to master a skill previously thought completely outside our abilities, or to unlock new possibilities of experience and thought. It’s exhilarating, life-changing, and (healthily) addictive, the same reason people keep coming back to see MoMA’s Pollocks and Picassos—and, we hope, this new group of humble masterpieces.

That’s how they are describing Arduino:

A tiny but powerful microcontroller, the Arduino is an open-source, programmable microchip housed on a circuit board that fits in the palm of one’s hand—an apt metaphor for the control over design functions that it allows its user—and a pillar of contemporary maker culture and practice. Designed by a star-studded team, the Arduino can be programmed to drive components such as sensors, LEDs, and motors in order to build and develop all kinds of interactive objects. This new building block of design has resulted in applications as diverse as light sculptures, digital pollution detectors, and tools to help people who are unable to use such common interfaces as a computer mouse. Beyond its concrete applications, the Arduino acts as a platform for the interdisciplinary practice that lies at the heart of so much compelling contemporary work across science and the humanities.

Art from Brainwaves, Antifreeze, and Ferrofluid

via Hackaday » » hardware

Screen-Shot-2014-09-08-at-18.57

Moscow artist [Dmitry Morozov] makes phenomenal geek-art. (That’s not disrespect — rather the highest praise.) And with Solaris, he’s done it again.

The piece itself looks like something out of a sci-fi or horror movie. Organic black forms coalesce and fade away underneath a glowing pool of green fluid. (Is it antifreeze?) On deeper inspection, the blob is moving in correspondence with a spectator’s brain activity. Cool.

You should definitely check out the videos. We love to watch ferrofluid just on its own — watching it bubble up out of a pool of contrasting toxic-green ooze is icing on the cake. Our only wish is that the camera spent more time on the piece itself.

Two minutes into the first video we get a little peek behind the curtain, and of course it’s done with an Arduino, a couple of motors, and a large permanent magnet. Move the motor around with input from an Epoc brain-activity sensor and you’re done. As with all good art, though, the result is significantly greater than the sum of its parts.

[Dmitry's] work has been covered many, many times already on Hackaday, but he keeps turning out the gems. We could watch this one for hours.

Layer Cam: the lensless tourist camera in a lunchbox

via Raspberry Pi

Have you ever noticed the way that everybody takes the same photo when doing the tourist thing? Just look at Google: there are a million pictures of people punting past King’s College Chapel in Cambridge out there, all taken at the same angle, from the same position – and they’re all online. So why do we (and I’m just as guilty of this as everybody else) spend precious time taking pictures of something that somebody’s almost certainly taken a better photo of already?

SaladeTomateOignon in Paris, another photogenic city, has noticed the same thing.

He says:

28 million people visit Paris every year, taking dozens of pictures each. Every building, every statue has been captured, under every sky and every light.

Because billions of pictures of the Eiffel tower have been taken, I am sure that you can find matching cloud patterns in dozen of them, even if taken years apart.

Pictures have been taken with simple pin-hole camera, smartphones or with the most complex and expensive large format silver film camera or DSLR, and lots of them are now online.

On the Internet, those photographies are sprinkled over the city, with some areas densely covered, and other more sparsely. Each website is like a stratum of pictures of every kind: postcards, paintings, photos, satellite images…

Layer cam is a project to tap into those layers, like a drill extracting a core sample of images.

Based on a Raspberry Pi, connected to the Internet through wifi and geolocalized by a GPS chip, Layer cam runs with Python code (mostly made from bits of code I found here (Martin O’Hanlon) and there (disasterjs) and taps into Panoramio API. The ‘Layer cam’ logo has been designed by Alice.

We love this project. It’s just the right amount of pointless, it’s in a Tupperware box, Paris is beautiful, and it made us smile. You can find out how to build your own at saladtomateoignon, with code and physical build instructions (which involve rubber bands and duct tape, like the very best of projects).

Art Showcase: Binaudios

via Raspberry Pi

Hey all – Rachel here!

I have spent the last year talking with lots of artists who are making amazing things with Raspberry Pis. Every day my inbox is PINGing with exciting progress news. So I’m going to start showcasing some of these projects on the blog. I find them incredibly inspiring – I hope you do too!

I’m going to kick off with a piece from one of my favourite artists: Dominic Wilcox. I bet you’ve seen some of his work kicking around the internet – He made the GPS shoes which guided you home and did some narrative sculptures inside watch faces.

binaudiosmam

This time he’s partnered up with Creative Technologist James Rutherford to produce Binaudios; a device that enables the user to listen to the sounds of the city – at the moment it’s installed in the Sage Gateshead music discovery centre.

binaudistesting2

Taking tourist binoculars as inspiration, the Binaudios can be pointed at over 40 different locations, seen out of the Sage Gateshead windows. Turn the giant listening cones toward the football stadium to hear the crowd chanting or to the Tyne Bridge to hear King George V’s speech when he opened the bridge in 1928. Point it toward the park to listen to sounds such as skateboarders and local tennis players.

As the Binaudios are rotated the stereo sounds move from one ear to the other creating a real feeling of listening to the city across the river.

binaudios3

I’ve met loads of ‘Creative Technologists’ on my travels. They believe creativity and art are the driving forces behind the technology they make.

James describes his work as “somewhere between code and art”. He mainly creates software; developing visualisations, data tools or games.

BoKf_LJCAAEPQMi

Binaudios was his first Raspberry Pi project AND first go with Python! Just for you guys, he has very kindly written up how Binaudio is put together:

How Binaudios works:

Although Binaudios was developed to look like an analogue device, there’s a small selection of electronics concealed within the central wooden box. A USB lead runs up the central column, powering a Raspberry Pi. This is connected to speakers within the metal cones and a USB hub. The hub adds some extra flash memory and has a couple of ports for attaching a keyboard and mouse for debugging.

Dominic recorded a selection of sounds from across Newcastle. I load these when the device boots. There are around 40 of them, spread across the 180 degree range of movement provided by the ear-cones.

The Pi has a PiBorg XLoBorg sensor attached to the GPIO port. The XLoBorg returns a 3-axis reading of the magnetic field at a point. The Python script very roughly converts this into a compass heading (to do this properly is extremely complicated- so this is a bit of a hack). I spread this heading into two angles a couple of degrees apart to fake some left/right ear separation, pick the sound clips within a small range of these and assign some volumes. The volume profile drops-off over a few degrees which produces a naturalistic ‘telescope’ focus effect. The left/right separation also enhances this as the unit is turned.

The rest is all about smoothing. I debounce the output of the XLoBorg (it has a slight natural waver), ensure volume levels are adjusted gently (audio buffering can cause the sound to chop otherwise, which is very unnatural) and keep the sounds playing even when they are a few degrees out of audio range (this means that sounds don’t necessarily need to restart from the beginning when they are back in ‘view’).

Gotchas

The XLoBorg is a sensitive bit of kit, and magnetic fields are complicated (who knew!?). I needed to spend some time calibrating and recalibrating. Slight vertical misalignment seems to shift the compass heading much more than I first anticipated. It’s a very intriguing bit of hardware and I look forward to playing with it some more!

My test set of samples worked wonderfully, but the program failed critically when I got the real clips- some of the sounds would work, but the rest would make a single pop, or a loud, painful high-pitched wave. I never fully figured out why, but I think I was maxing out Pygame’s audio channels. Originally I was playing all of the sounds simultaneously and just shifting the volumes around (so that all but a few were zero), but I switched this to just trigger those within a small angle range – so it now plays maybe four or five at the same time. There was no failure response from the code, so I spent a manic day trying to squash, re-encode and generally poke the samples about without error reports to work on. Thankfully, the fix seems reliable.

This was my first physical project, first Pi project, and first slice of Python charming!

You can see them in action in this video or you can go and visit in person!

Binaudios was commissioned by the awesome Suzy O’Hara at Thinking Digital Arts.

Does your Raspberry Pi belong in a gallery?

via Raspberry Pi

It is a beautiful piece of hardware and I’m sure takes pride of place in many a building, with scores of people gazing upon it in wonder, especially if you’ve hacked it to do something cool. But is it art? Google Developers certainly think so, and have launched Dev Art: Art Made with Code mid-February, as an open platform that allows artists to share their digital art with the world and also detail the process they took to create their work in a unique way. If you have not already checked out the site, then I would highly recommend doing so. Raspberry Pi is listed as a platform, and there are some examples of its use in this project such as the Wireless Poetry Installation.

As well as the Dev Art website, Google have teamed up with the Barbican in London to host an exhibition of digital interactive art this summer and they are offering anyone the chance to exhibit alongside some of the worlds most well known digital artists in this exhibition through their Dev Art competition.

The winning creative coder will receive a budget of £25K, Google Developer support as well as curational and production support from the Barbican to help realise their concept into a digital art installation.

 

The Top 10 Finalists will have the opportunity to meet the DevArt judging panel during a Google+ Hangout, along with a ‘DevArt Finalist’ award for their site.

We know how powerful art can be in teaching computing skills since working with Dr Sam Aaron on Sonic Pi, and watching our own Artist in Residence Rachel Rayns lead workshops. Now it is over to you! We hope that the wider Raspberry Pi community will feel motivated to submit their projects to the Dev Art competition. Who knows, maybe you could be exhibiting at the Barbican!

 

 

Exploded Hardware Wall Art

via Hack a Day» hardware

explodedHardwareWall

The gang at Bolt.io realized that the walls in their office deserved some special attention, and they got it by mounting exploded hardware throughout the space. They sourced the used devices from eBay, then carefully broken them down into their components and mounted each on its own sheet of PETG. The result: exploded views of some of their favorite hardware, including a MacBook Pro, a Roomba, a Dyson Air Multiplier, and more.

Is it a hack? Eh, maybe. This is the first example we’ve seen of a collection of devices on display in this fashion. Regardless, it’s worth a mention considering what happened in the office as a result of the installation. Though the original purpose was simply to decorate the walls, it seems employees have been staring at them regularly, learning more about the designs, the plastics, and the component choices. Think of it as still life—depicting that moment you cracked open a device to inspect its guts—frozen in permanence and on display for both inspiration and convenience.

Bioscope – old-timey-fy your movies

via Raspberry Pi

We met Jon Stam at a Maker Faire last year. With Simon de Bakker, he’s made the Bioscope: a Pi-driven nostalgia machine. Part art project, part toy, it’s extremely simple: upload any digital movie onto a USB stick, pop it in the back of the Bioscope, and peep through the viewfinder.

But rather than just watch the movie play away, you have to move it yourself along by turning the red handle. Pause by stopping the handle, rewind by turning it backwards: and the whole thing has a lovely jerky, old-timey feel to it; the vintage feel underscored by the 3d-printed case, which is based on a copy of an old Fisher Price movie projector toy.

Jon and Simon are using the Bioscope to make an artistic statement about the way we interact with moving visual media. We like it for its satisfying shape and feel, for the way it reminds us of toys we had as kids, and for the cameo appearance of the Numa Numa guy in the above video.

The Bioscope guys have created a custom PCB that sits on top of the Raspberry Pi, which allows you to power the device from a single 3.7v lithium-ion cell. You can find some more technical details of what the custom PCB adds at i.materialise, where Jon and Simon had the case 3-d printed.

Right now, there don’t seem to be any firm plans to commercialise the Bioscope – we hope Jon and Simon do take it in that direction, because there’s something enormously appealing about it. We’ll let you know if we hear anything.

Lo-fi display made of 64 wooden blocks

Wooden Pixel Display 64 - WPD64

Han Lee wrote us to submit a project about analog wooden blocks  acting as digital pixels and controlled by Arduino. Wooden Pixel Display 64 is composed by 64 wood pixels in a  8×8 grid and originally prototyped  using Lego:

One pixel might make you bored but it gives you something interesting when pixels make a form together. This WPD64 has been presented at a generative art show in NYC recently.

I used Arduino Uno and four of Adafruit 16-Channel 12-bit PWM/Servo Shield to control 64 servos. Laser cutting service from Pololu.com for the front cover which should have 64 square holes at the perfect grid.

‘conus’ mixes media, math and mollusks

via Hack a Day» hardware

conusCA

We love art installations that use technology in ways probably never before considered, and Moscow media artist [Dimitry Morozov] has done just that with ‘conus’, which reads the surface of mollusk shells and translates the data into real-time audio and video. These shells are unique; their pigmentation generates natural cellular automata. (If you’ve never heard of cellular automata, Conway’s Game of Life is a good example, where a rule set determines whether a cell lives, dies, or regenerates.

[Dimitry's] installation uses homemade digital microscopes to scan the naturally-created cellular automata of several shells, each rotating on its own disc. As the shell spins, the scans from the microscopes are fed into an algorithm which transforms the signals into data for multiple audio channels and three video monitors. You can watch the mathematical translation of the biologically-formed patterns in a video after the break.

Check out the MSP430 game of life shield for another example of cellular automata.

Tudor theatre, 21st century technology

via Raspberry Pi

This summer, Shakespeare’s Globe theatre in London mounted a production of all three of Shakespeare’s Henry VI plays, staged both at Shakespeare’s Globe itself, and outdoors at battlefield sites from the War of the Roses. The theatre collaborated with The Space, a new Arts Council and BBC-developed service which streams free, on-demand video of live cultural events, to produce a broadcast of the plays from multiple viewpoints.

Real live camera operators, with real live cameras, were following the actors around and filming the whole series of plays. But we are particularly interested in one specific camera: the tiny Throne Cam, invisible to the audience, but filming all the proceedings from the huge throne which forms part of the stage set in all three performances, giving an actor’s eye view of the plays. It was a Raspberry Pi camera board.

Thronecam in situ at Shakespeare’s Globe

It turns out that the Pi and its camera board are the ideal solution for The Space. The whole assembly is not big enough to be noticeable by the audience if it’s mounted somewhere on the stage, but can record 1080p HD video. And, because it’s driven by a Pi, it can process and encode the video onboard, so no additional work needs doing by The Space to publish the stream online.

The first of the three plays is already available to watch online. I’m on a very wobbly hotel wifi network today, so I haven’t been able to watch the video yet – please report back in the comments and let us know what you thought of it!

This is your brain on Pi

via Raspberry Pi

We’ve only just spotted Mens Amplio, an Indiegogo project which met its target last month. It’s now being put together for the Burning Man festival, where it’ll be displayed in a couple of weeks. Mens Amplio is a fifteen-foot tall, Pi-controlled sculpture: a part-buried, giant human head made from an enormous mesh of steel. And inside, there’s a brain packed full of Endlighten acrylic rods for its neuron branches, which diffuse light from LEDs along their length.

Those lights are controlled by the brainwaves of a test subject volunteer wearing an EEG headset, changing shape and colour depending on the user’s thoughts, as interpreted by the Raspberry Pi; the eventual result is being engineered to mirror what you’d see on an MRI scan. You can read more about the work they’re doing to light up that giant brain on the Mens Amplio blog (it’s worth digging deep; this is a really interesting build), and keep up with the current state of the code they’re using on Github.

Braaaaaains.

Flames, also controlled by the Raspberry Pi, will be shooting out of the top of the thing.

The Mens Amplio team is made up of people from all the backgrounds you’d need for this sort of thing: doctors, welders, graphic designers, Alzheimer’s and Parkinson’s researchers, electronics engineers, brain imaging specialists, kinetic fire artists – here they are, in the video produced for their (now completed) Indiegogo fundraiser.

If you see Mens Amplio at Burning Man this year, be sure to take some video and send it to us. Best of luck to the ladies and gents of the Mens Amplio crew – we hope you have a blast on the Playa!

Know about an art project using a Pi that you think we’d be interested in?

Please tell us about it: while the hacker community is never backwards about coming forward, we’ve found that artists are curiously shy about approaching us when they’re using a Raspberry Pi, and we often learn about the Pi component of art projects like Mens Amplio too late to put the word out about fundraising or exhibitions. Rachel, our Artist in Residence, is busy doing artist and kids outreach, and we’ve got projects running with the UK Arts Council to introduce the Pi to young artists. We know there’s much, much more out there, but we need you to tell us about it. If you’ve seen something you think we should blog about, you can reach me at the usual address.
