Every word is like an unnecessary stain on silence

via Arduino Blog

silence

« Every word is like an unnecessary stain on silence and nothingness » is a sentence from Samuel Beckett but also the title of Eugenio Ampudia’s last artwork created and installed with the support of Ultra-lab  and running on Arduino Mega and GSM Shield:

The exhibition room has in its center a rectangular mirror made of water that reflects the room and the visitors. The perfect still water, metaphor of silence, is broken by the irruption of sporadic waves. These movements, the stain on silence, are provoked by the visitors’ interactions. In the heart of the water tank, a dispositive is able to receive calls and to open a valve. To each visitor’s call, so a series of movements is generated and break the calm.

Ultra-lab realized the technical part of the artwork thanks to an Arduino Mega, the Arduino GSM shield and various valves open and close by the Arduino Mega when a call is received by the shield. The dispositive is particularly interesting for its adaptation in a water context and for connecting valves.

Thanks to it, the artwork succeed to express beautifully the paradox between a destructive attraction for words and communication to which it’s hard to resist in order to prefer a finally inaccessible contemplation.

The work can be visited in the exhibition room Abierto X Obras in in the Spanish art center Matadero Madrid until the 17th of May 2015 and below you can watch a video interview with the artist:

Duelling pianos. Literally.

via Raspberry Pi

When someone mailed me a link to this performance, I assumed it was going to be one of those setups where two pianists play jolly tunes together in a bar. How wrong I was.

These two pianists (Alvise Sinivia and Léo Jassef from the Conservatoire National de Paris) are trying to kill each other in Streetfighter. Tunefully.

These pianos have been transformed by Eric and Cyril of Foobarflies (let me know your full names, Eric and Cyril, so I can add them here!) into Playstation controllers, using piezo triggers, a Pi, some Arduinos, and some custom Python firmware. The installation was set up for the reopening of Paris’ Maison de la Radio, now a cultural space open to the public.

Eric and Cyril have made a comprehensive writeup available (and if, like me, you’re terribly excited by the insides of pianos, you’ll love this one). This is one of my favourite projects in ages – thanks Foobarflies!

Thirty-five Pixels, powered by Raspberry Pi

via Raspberry Pi

Creative Director and Interactive Developer Michael Newman was tapped by UCLA Extension to design their 2015 winter course catalog cover. To accompany his work, he also designed, developed, and built a Raspberry Pi-powered interactive installation called Thirty-five Pixels which is currently on display at UCLA Extension’s 1010 Westwood building through the 2015 Winter Quarter.

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.
