Art that explores questions raised by modern society – about privacy, surveillance culture….

September 23rd, 2012

STANZA’s art explores questions raised by modern society – about privacy, surveillance culture, and who owns the data that is regularly collected about all of us – often using modern technologies to create his pieces. Since he first started exhibiting his works in 1984, STANZA has strived to create cutting edge art that deals with current issues. In the process he has won several impressive awards, including an AHRC arts fellowship, and has seen his work featured in over 50 different exhibitions globally.

Ahead of a installation of one of his works “Capacities” in Ghent, Belgium in September, Solomon Radley met with him, in front on a computer monitor at his studio in South London, to talk in depth about what he does over coffee.

Hey, how’s it going? Would you begin by telling me a bit about what you do?

STANZA: The things that I’m interested in are ‘surveillance space’, which is the idea of the city as having become a panopticon – this idea that we’re in a prison and we can be observed at all times, from all perspectives, all at once, and particularly in real time.

I use various technologies to do that, like CCTV and wireless sensor networks. Over the years, firstly I’ve developed a strong understanding of what these technologies can do in terms of learning about them, but also I’m having to develop for them, so I’ve learned how to develop hardware and software. You may think I’m a technologist – I see myself as a creative technologist, and I also see that artists are engineers, so they have to understand the technologies that they use, and the mediums that they use in order to get output.

To bring that into perspective, we can look at some artworks…

Sure thing. Would you expand on your thought that the city is a sort of prison?

STANZA: Urban Generation is a piece I did in relation to this idea of the city being a panopticon. Let’s say, in modernist terms, an artist would go out and collect assets – he might use a recording device or a camera – it would be a still, linear asset, and it would never change. It’s possible to actually conceive of the city as a moving physical entity, moving forward in time all the time. How is it possible to use new technologies to actually gain a representation of this, and use it in a culturally meaningful way?

Urban Generation attempts to imagine the world from everyone else’s perspective all at once. If I’m giving a talk, what I try and do is – to illustrate the conceptual shift – I say: “I’d like you to close your eyes, and I’d like you to imagine yourself in a place in London. I’m going to do the same and I’m going to take a single mental snapshot, and I’d like you all in the room to take your single snapshot. Now, I’d like you to imagine the view of the people sitting next to you to your left and to your right, so you have three images multiplied together. There’s 300 people in the room; I’d like you to merge all of these 300 images together. And now not like a film, (because if we used a film we’d be recording the same images) what I’d like you to do is to move these images forward in real time.”

This is the idea I’m trying to capture with this piece of work.

A lot of your work is concerned with the question of who owns the information that is regularly collected about people, and with re-claiming that information. Tell me about this idea.

STANZA: I make artworks that arise from my research into these themes – the themes being ‘control space’ and ‘surveillance space’ and issues with privacy. What I’m doing, which is sort of new ground, is that I’m hacking access to a network and re-appropriating the data and information, and I’m re-contextualizing to give it a wider meaning. I want to show that you can do something positive with this data.

Other works where I’m interested in the control and ownership of data include this website called GenoMixer, where I fully sequenced my blood. In a sense this looks like artist self-portraiture, but I was interested in thedomain space – the public domain space – that’s inside our bodies.

We have this huge line of code – 3.3 billion letters – and it basically has an economic value. The proposal here is to IPO (Initial Public Offering) the project on the stock market, and to give everyone a share of the derivable intellectual royalties. For example, if somebody else wanted to investigate your DNA in a medical program they’d have to pay you. If some other company discovered the cancer gene because you were on the police forensic database you could say “No it’s copyrighted – it’s on the GenoMixer database”.

It just so happens that I also made a series of self-portraits with them…

One of the most obvious types of information that is commonly collected about the general public is video images gathered by CCTV, and this is something you often look at. What are your thoughts about CCTV?

STANZA: Let’s look at “Urban Generation – trying to imagine the world from everyone else’s perspective, all at once“. What we’ve got here is: each square on this four-by-four grid is making calls to over 100 cameras in London in real time. This is a parallel reality, using live network data to re-appropriate it over the network and use it for something else. For example, this could be used as an extension on landscape painting.

Why this has become quite interesting, and the reason I mention these modernist aspects that are fixed, is that this work is never the same. You could look at it even now, on a different monitor, and it would be different: It’s not the Mona Lisa – where every time you look at the work you experience the same thing – there’s an added problem here.

Another interesting question here is: Is what we’re looking at the artwork? On July 7th in 2005 they switched this entire network off because of the terrorist attacks. Well my system still worked, it’s just that the output – which is what connects a viewer to the system – is shifted.

This [Public Domain Responsive Architecture Facade] is the same concept using CCTV, observing the whole of the city but making it transparent. Why would you want to make your movements open and transparent? Why would you want to let CCTV be seen by everybody? This is a building with its outer surfaces displaying images that are embedded in the city – all the stuff on the outside of the building is shifting in terms of the real time properties of that city. In a sense, you (as the observed individual) become part of the building and part of the city, and this opens up the idea of transparent architecture and transparent space.

Public Domain is another work along the same theme, where I gave CCTV cameras away to members of the public, to open up this idea of CCTV networks. People sometimes say that they’ve got nothing to hide, and to nothing to fear…I think that’s a problematic statement. I’m not coming down on a particular side of the fence here, but it seems to me that we’ve opened Pandora’s box, and there’s a whole series of legislative and ethical issues that aren’t being addressed.

Hopefully what I’m doing in these artworks is to draw attention to the fact that there’s a whole series of potential problems that we’re walking in to.

You also play with collected data, which you use to create interactive works or installations where real-time changes are caused by environmental factors…

STANZA: We’ve already looked at my CCTV system. There’s another one, which uses wireless sensors/wireless nodes. You scatter them across the city, and they talk to each other in a network grid.

This research started in 2004 as a result of an AHRC grant that I was awarded, and I was trying to find a system I could use as open source hardware and software, that would monitor the whole city space. I’ve scattered these sensors around a city to generate visualisations and sonifications in various cities. For my first project [Sensity] they were output onto a visual globe.

So, now what I was interested in doing is looking at this real time data, that’s now everywhere, and seeing if I could do something else with it – if I could make art with it.

Equally, in Sonicity I deliberately put a whole load of speakers on the floor and connected them all up to make it look like a map, and somewhere else (in another part of the world) that data is being collected from my network and being spat out onto the internet via an XML stream. In arty terms, maybe I’m “painting with data” – the data has become the medium. With this data I’m painting a sonification of the real time landscape.

The second thing I was trying to think about, as part of this thinking process, was all the stuff that’s being collected about us – not just my data, but tax data and medical records – which could be used because of the way it changes and shifts from one thing to the next to power other events:

With CapacitiesI made…let’s call it a sculpture…a sculpture of computer parts that looks like a city, and would be powered by events changing somewhere else in real time. In this version of Capacities, all the lights and fans, and all the parts that change, do so because of other things happening in the world in real time.

The reason I’m trying to do that is that there seem to be other values that people are missing in terms of the things that are happening to us, and the world, in real time. We’ve become bodies residing in a ‘data space’. Everything around us is the data space and by default we interact with it – even small movements displace millions of atoms.

I conceive of this post-modern world in which movements are just moving a series of 0s and 1s. I can measure the 0s and 1s that I’m displacing by moving around. This interactive process is embedded in the work by default.

Visitors to a Gallery… is quite an important work, in that it opens up the gallery space as an artwork. For example, these two people that are pictured aren’t actually in this room – they’re in another room in another part of the gallery, so they’re embedded in the artwork that you’re viewing. Everybody in the architectural space becomes part of the artwork, and this happens in real time – it’s not recorded, and it’s not a film. So I utilize the technology in the space (the CCTV system).

Secondly, what’s happening here is that there are a series of proximity sensors that affect this as an algorithm – as you walk around this space all of these images oscillate/vibrate slightly.

So when you’re in the room, viewing this artwork, you’re at the same time generating an artwork for someone else in another room?

STANZA: And you’re in the work you’re viewing yourself, through your interaction with the sensors.

That’s also happening in Seeing Through Walls, where there are little cameras and monitors, so you become embedded in the same artwork as it’s being broadcast live, or in this piece where you can see through to people on the other side of the wall.

I was actually in a Greek club where they had something like that – the mirrors in the toilet let you see yourself, but also the women doing their makeup in the adjacent toilets…

STANZA: Ha! No wonder their ecomony’s gone down the pan…

Moving on from that, my work splits into this idea of using real time networks and investigating different ways of interacting with public space.

Here’s a strange project called The Binary Graffiti Club, where I got a load of people to dress up in hoodies with 0s and 1s on their backs, and they go round the city making binary graffiti – painting little coded messages onto the city.

Anything in particular?

STANZA: Well…no. I don’t want to be too specific about this, because… Well here’s a piece going back to the DNA project (the open source bit). If you sit in the gallery for…this has been online for seven years: If it was exhibited in a gallery you could get my open source DNA, and you could go off and replicate me, but it changes a letter once every second so you’d have to sit there for 104 years with a pen and paper. The same is true of the binary graffiti club – if you want to know what the message is, you have to sit there and transcribe it and translate it.

One letter from STANZA’s DNA code – the letters are shown in order, one per second for the 104 year project

This led from another piece of work – A City of Bits – as well as this performance that was laid down in the form of this sushi: I invited 12 people, after the disciples, and asked them to come and eat this coded sushi message. So, this is a coded message that they eat, and then they all put their own message back into a jar which I’ve now destroyed. I’ve transcribed those messages here…

You have a performance coming up in Texas soon – tell me a bit about what you’ll be doing.

STANZA: In Soundcities, using a recording device, I’ve been to all these different cities, recording sounds which are attached to Google Maps, and you can visit lots of cities in the world…

The key to this is the database; you can see the sounds, arranged in different categories, and you can create a performance by picking a selection of them and building up rhythms. This is what I do with my performances, except I have the same thing on a couple of machines, and I might mix it with sounds from churches, etc. It’s basically a live world tour of city sounds as music: the machines are connected to a mixing desk, images are coming from the website projects.

During the eight years I’ve been doing these performances, they’ve been heavily focused on the sounds of cities, the database live and soundmaps.

So this database can be used in performances, but the key here is that the database is open source, and other people can contribute to this community of sounds. There’s lots of other projects that have come from this, but the most important bit is this. This XML feed shows the sound, and its longitude/latitude, and although this is just a line of code it basically means that anyone else can use this to write their own apps.

What I’m doing that’s unique here is: it’s like an artist of the past allowing someone into their studio to work in parallel with them.

Sonicity Installation is exhbited in Germnay  for Stuttgarter Filmwinter Sound Installation, Great Britain 2011.

“Sonicity” is a responsive installation, a sonification of the real space and environment. This artwork focuses on the real time space and the experience of the gallery visitor as they interact with the space, using data gathered from these new technologies. My system monitors the space (the building) and the environment (the city) and captures live real time data (light, temperature, noise, humidity, position) to create an ambient sonification, an acoustic responsive environment, literally the sound of the micro incidents of change that occur over time. This artwork explores new ways of thinking about interaction within public space and how this affects the socialization of space. The project uses environmental monitoring technologies and security based technologies, to question audience experiences of the event and space and gather data inside the space. The project also focuses on the micro-incidents of change, the vibrations and sounds of the gallery using wireless sensor based technologies.

The sounds you hear are the sounds of the changing environment, i.e. the changes of noise, light, temperature of the space is turned into a real time sound stream using dozens of wireless sensors presented as an installation on 170 speakers.

Soundinstallation, Großbritannien 2011

“Sonicity” ist eine reaktionsfähige Installation, ein Hörbarmachen von realem Raum und realem Umfeld. Die Klänge, die man hört, sind die einer sich verändernden Umwelt, das heißt Veränderungen von Geräuschen, Licht und Temperatur werden mithilfe dutzender kabelloser Sensoren in einen Echtzeit-Soundstream umgewandelt und als Installation aus 170 Lautsprechern präsentiert.

Die Arbeit konzentriert sich auf den Echtzeit-Raum und die Erlebnisse der Besucher wenn sie mit dem Raum interagieren. Dabei werden Daten, die durch diese neuen Technologien gesammelt wurden, verwendet. Mein System überwacht den Raum (das Gebäude) und die Umwelt (die Stadt) und erfasst live die Echtzeit-Daten (Licht, Temperatur, Geräusche, Luftfeuchtigkeit, Position) um die Umgebung in Form von Tönen abzubilden, eine auf Akustik reagierende Umgebung, buchstäblich der Sound der Mikro-Veränderungen, die sich im Lauf der Zeit ereignen. Das Kunstwerk untersucht neue Denkansätze über Interaktion im öffentlichen Raum und wie sich diese auf die Sozialisation des Raums auswirkt.

Das Projekt nutzt Umweltüberwachungstechnologie und Sicherheitstechnik, um die Besuchererlebnisse im Raum zu hinterfragen, wobei Daten im Raum gesammelt werden. Das Projekt beleuchtet auch die Mikro-Veränderungen, die Vibrationen und Geräusche der Ausstellungsräume mit drahtloser, sensorenbasierter Technik.

I am developing the idea of studio as laboratory and extending previous versions by inviting members of the public to be involved in the process and the experiments. The studio will also have live CCTV broadcast and live data feeds.

Artists are like scientists they ask questions and find answers in peculiar ways….guided by research and process development.  Most artists, like scientists do stuff, they make things to question the world. They often speculate, researching difficult issues in a general direction in the way they see it with specific outcomes, these outcomes may or may not be art.

From the real to virtual and back to the real is a theme that has had my attention for five years and the idea is embedded in the works I am currently making.

This project will take place in the Barn at Lanternhouse, as Stanza creates data scapes in an Open Studio.  The residency is about exploring the artistic process, being transparent about the process and the development and production of new work.

The “open studio” mirrors the process of the project, with material and philosophical process being available to witness throughout.

The ‘environment’ in these projects is created from a wireless multi nodal multi sensor network that is in place. The network emits live data via a proxy server and the online xml data gateway represent a live communication flow of the city space. This impression and this part of the work is what I term asset gathering and in this case they are constantly gathered into an online system ready for interpretation.

The online interfacing of live real time sensors networks allows a communication with environment, with real space in the present. Control mechanisms of ownership and rights access are opened up my making the data available in the public domain. These real time impressions can be modulated from online interfaces to physical sculptural interpretations.

The data is remade real again as physical objects interpret the virtualized readouts. The analogue is made digital and the digital can be formed into a variety of output devices. The data can be represented as online interfaces like I have made (Sensity , House, both online), or by triggering the technology in the physical world, ie sensors, Leds, displays, robots etc. Sensity can trigger buildings relating to whole cities, or vice versa. The flow of the data can be set to affect the behaviour of the output environment.
The data environment that is created is a mapped on top of the space, a virtual data map or the real world.

Other artists are also allowed access to this “back end city, real data city and they can make their own “Sensities”. In this way the data is open sourced. From any Sensity network numerous artistic interventions can take place. In fact the whole city can be represented, and all artists can make multiple work from this “The Emergent City”.  A city of sculptures re-presenting  real time space.

Networked Cities By Stanza. Sensity project. 2004 – 2010

Within Sensity there is now a loop from the real to the virtual and back to the real.  This notion of playing or manipulating with a malleable form (data) is made possible as each stream, each node, each sensor, or even the entire network can be communicated with using this xml online gateway.
We have seen rich shift in relational and responsive interactive works and the move away from gallery as a venue for art to the use of architecture and public domain space in the last twenty years….stanza

In an age of global warming, so many artists are still using the architectural space as a coloured light bulb. As we burn more fossil fuels the light are flashing on and off. Sensity be made more physical on output to represent of the growth of the city as an experience in the real world away from the screen. A city representation of the fabric of city space end the emerging patterns caused by these data flows. An art city can be made where the data powers the wind turbines, the data changing the solar panels that change the lights. Loops of real time data change the meaning all the while changing the  input and output  which is (e)merging into a new space.  Also  see my new works Tree, Sonicity and Capacities.

The Emergent City. Online visualizations, the networked city.

Stanza City: Generative Software System.

This text is a transcript of one of my talk about my work The Emergent City.

My current work remains focused on the creative use of technology integrated into urban space.My areas of interest include investigating new concepts for the relationship of the physical body, emergent data and real space in the built environment.

As an artist I am trying to create artistic metaphors for new creativity using new technologies and integrating new media artworks into the public domain. As an artist I am trying to create artistic metaphors for new creativity using new technologies and integrating new media artworks into the public domain. There are three strands of my working process; these involve; collecting the data, visualizing the data, and then displaying the data. The outputs from the online interfaces and online visualizations can be realized as real time dynamic artworks as diverse as installations, and real objects, made out of new display materials back in physical space. In all my work I try to exploit the changing dynamics of city life as a source for creativity and create meaningful artistic metaphors. I utilize new technologies and integrate new media artworks into the public domain as part of this ongoing research into the visualization of city space.

In essence I am researching data as a medium for creativity and how meaningful experiences of our cities may result. From a technological peprspective, I am researching sensors , motes, new display technologies and interactive architectures. This research includes investigations into…..Concepts for the relationship of mobile computing within urban space and the built environment.

The Emergent city is to be a group, a body of artworks that I am working on all connected by a central theme. As you know a city is a web of connected networks. In essence, the city fabric is a giant multi-user, multi-data sphere. The city is made up of traffic patterns, pedestrian patterns, bird flocking patterns. Patterns can be seen in the architecture, patterns in the buildings, patterns in the architectural fabric of the urban design network. All of these spheres can be represented by media and therefore by data within the digital realm. And all of this data can be interpreted and mediated. It becomes a matter of choice. Collections of data can be stored to be retrieved later. The mobile data infrastructure becomes a data source so powerful so interwoven that its scale can only be imagined as metaphor. The size and scope of such an archive, of such rich mediated data experience can support many projects. As such it can be interpreted via a variety of interfaces. Cities offer the opportunity for unique types of data gathering experiences via a variety of sources.

My objective is to ‘mediate’ data into conceptual artifacts. With this perspective there are many unimagined threads of data and connections that describe our world that can be explored through wireless mobile networks within which we can create artistic interpretations. There are various types of data can be re-imagined. This includes pollution data recorded via sensors in the street, to create audio files. Weather and forecast data, acquired via weather station equipment, this can be used and can create ambient soundscapes and morphing visualisations as the wind shifts direction or the rain increases. Noise monitor levels, and noise maps, create a symphony of true urban sounds that can be used to make sound reactive sculptures. So under this umbrella of ‘the emergent city’ project I have made a number of works that have move beyond the process of research, beyond what I term as asset gathering, into what might be alpha beta projects. An example of this is my URBAN GENERATION project. I have also made the online database for soundcities which now has 2000 sounds online line in it. So other artists can interface to it. Memory mapping. About traces and memories of urban space. Multiple viewpoints of data cities. The city also has millions of CCTV.

In essence the city is the biggest TV station in existence. Millions of hours worth of data are recorded every day by these cameras on city TV. One can take the sounds and images off live web streams and re-represent them thus creating new interpretations of the city in the process. The city already has a recorded source of data, CCTV is everywhere. Using data from CCTV, you can bring the outside inside. Selected feeds are collected from around the world in real time. These real time images are fed into a software system where a series of specialised channels rework these images. The channels are always on, and always changing, a constant view of the world changing and evolving around the clock. This uses specially created software and technology to randomly find images in real time from anywhere in the network, in this case anywhere in the world.The increase of technology infrastructure in the daily existence of a city means that technology will, more than ever be everywhere in our environment. Mobile data mining will be part of the fabric of the landscape. We will be carrying this data in pods, phones and ID cards. Everything is or will be tracked. CCTV, car sensors, tracking inside our phones and id card movement tracking in the guise of anti- terror activity. The patterns we make, the forces we weave, are all being networked into retrievable data structures that can be re-imagined and sourced for information. These patterns all disclose new ways of seeing the world. The value of information will be a new currency as power change. The central issue that will develop will be the privilege and access to these data sources. Uses of this information and data should allow rich new interpretations on the way our world is built, used, and designed.

So we need to imagine the city at a different scale. The possibility is to extend our imagination and enable that perception of the city as a dynamic network. We can now put systems in place that can re–employ our perception and thus create new understanding of how this behaviour unfolds. There are patterns, they are connected and the systems that evolve, can be simulated and acted upon. We can influence the process and the system and we can also create variables into this system that allows understanding of the bi-products of the system, the data and the resulting information Currently a research fellow at Goldsmiths Digital Studios.


Datacity: Sensors In The City. Stanza Visualisation.

I am scattering the city with sensors. Hundreds of them, some fixed, and some embedded, to access these data structures and to claim them for the public domain within the realm of social sculptures.I am trying to make smart networks that have data open to all, and not closed off spy surveillance oriented systems. The networks could be thought of as open social sculptures that can inform the world and create new meaningful experiences. Thousands of motes can be deployed across the city for gathering data in wireless sensor networks. Used in large numbers they can communicate with one another via radio signals across the network. They can reconfigure themselves, so that the network stays stable. The data is chanelled through a system to a point where it can then be interpreted. So the concept is to embed the city with thousands of motes to gather data for the creation of artistic artifacts. The motes can monitor sensors such as temperature, sounds, light, position, acceleration, vibration, stress, weight, pressure, humidity, and GPS. Motes and sensor boards can monitor the micro incidents of change in the city, the noise, traffic flows and people flows. The interactions of all this data, controlled via mixed up interfaces that can re-form and re-contextualise experiences in real time as social sculpture. Imagine walking out the door, and knowing every single action, movement, sound, micro movement, pulse, and thread of information is being tracked, monitored, stored, analysed, interpreted, and logged. The world we will live in seems to be a much bigger brother, than first realised. Its a world full of data that can help understand the fundamentals of our outside environment, and monitor the micro codes of our DNA, a world where we are liberated and empowered by data, where finally all of the technology becomes more than gimmick and starts to actually work for us.

So this is where I am at..scattering thousands sensors across the city and trying to figure this out.Sensity artworks are made from the data that is collected across the urban and environment infrastructure. I have a network of sensors which collects data, which is then published online. The sensors interpret the micro-data of the interactive city. The output from the sensors displays the “emotional” state of the city online and the information will be used to create installations and sculptural artifacts.These artworks represent the movement of people, pollution in the air, the vibrations and sounds of buildings, they are in effect emergent social sculptures visualizing the emotional state of the city. The sensor network can be moved from urban to rural setting and different types of visualization can be made depending on the environment. Sensity is an open social sculpture that informs the world and creates new meaningful experiences. Sensity is also a highly technical project that will give vast amounts of information about the fabric of our cities. By embedding the sensors like this we can re-engage with the urban fabric and enable new artistic metaphors within city space. The sensors are positioned across the city. Custom made software enables these sensors to communicate will one another in a network over a proxy server in real time. The data can also be used to create visualizations in an open source environment. Other online users can also re- interpret the data and interrogate the various sensors in the network as this is open sourced as well (see xml streams)l. Representations of these datasets will allow unique understanding of the urban environment and environment in real time. Motes are used to collect the data.


Datacity: Sensors In The City. Stanza Visualisation.

The ‘motes’ are tiny wireless sensor boards that gather data and communicate to the central server. The real world is monitored and the data stored in my archive retrieval system. Motes and sensor boards sense the micro incidents of change in the weather, the noise traffic flows and people flows. The interactions of all this data, controlled via interfaces that can re-form and re-contextualize experiences in real time. Sensity incorporates the holistic city system. The sense city is a city of, accumulated incidents of love, abuse and death. The micro incidents of change in the weather, the noise traffic flows and people flows. The archives of this data can be controlled via mixed up interfaces that can re-form and re-contextualize experiences in real time; to make emergent sculptures visualizations and sculptures. Sensity leverages the real time data city and represents it online showing the life of the system and the emerging changing bahaviours of the space. The data is the medium. Future cities will be merged real time connected up data cities. Sensity connects up networks of real time information flows. The results are mashed up cities and real time performative city mashings. The shared data space can overlap and there is a new space the space in between that only two nodes share. The aetheticization of the shared city space. I have merged collected data from various cities. The images below show an integrated architecture the space where the cities overlap and create a new architectural space. Technology. I now have several sensor kits both twenty nodes that can be placed up to 300 meters apart with GPS. I have made two versions of the Sensity interface software. One works with recorded data (ie recorded data) and one that works with the real time data, which means the sensors are switched on always and working through a router. The changing data is what affects what you see and experience. The sensors can monitor temperature, sounds, noise, light, acceleration, vibration, pressure, humidity, and gps. The sensors take a constant stream of data which is published onto an online environment where different interface can make representations of the XML and from this lots of artistic interpretations can be imagined.

The temperature sensors in moteview on four of my motes show -273.15. The rest of the board ie light and sound is working. How do I get the temp working or reset it.

Did you “Reboot” into the new image (slot) that you OTAP’d?

This is required in order for the nodes to start executing new image.

You may choose any of the available slots where you want to store the

new image.

Please refer to the MoteConfig manual for details on OTAP.


The temperature sensors in moteview on four of my motes show -273.15. The rest of the board ie light and sound is working. How do I get the temp working or reset it.



It looks like you are able to query the nodes (i.e. they are running OTAPImage).

Which Motes are you trying to reprogram with the new code?

Which slot have you selected to OTAP?

Please check and make sure that you have at least 2.7V battery voltage on these nodes.



Unless you had previously enabled the nodes to be OTAP’d you won’t be able to OTAP with new application.

What I would suggest is to bring the nodes and attach them to the MIB board and then program them using MoteConfig’s Local program tab. You need to chek OTAP enable box if you wish to OTAP them in the future.



May be I wasn’t clear earlier. You can use both CA and CB boards in

the same network. The main difference is that they use different power

control lines for temperature sensor. To get accurate temperature readings, you should Program the Mote attached to the CA sensor board (without jumper wire) with  “XMTS300CA__.exe and program the Mote attached to the CB  sensor board (with jumper wire) with “XMTS300CB__.exe



It is quite likely that you have an MTS310CB board (look for a jumper

wire on the bottom-side of the sensor board).

The MTS310CA uses INT2 for temperature power control where as the CB

version uses PW0. It sounds like you are using CA code on CB hardware (or vice versa) and hence the Temp sensor never gets turned on and returns 0.

If you have CB board, then you need to use CB version of the app.



We want the batteries to last longer.

How do we do this?

How long should batteries last without a change….

If they are in low power mode how long will they last.

I know know this is difficult to answer) but how do I get them to last longer.

Also do you have solar panel one can plus in to the motes for power?



The high power (HP) version of the apps don’t duty cycle the radio and hence would deplete the battery in few days. The low power (LP) version of the apps draw an average of 330 uA current with MICA2 platform and when used with alkaline AA batteries can easily deliver over 6 months of battery life.

In order to make the batteries in the Kits last long time, you need to use them in XMesh-LP mode.

We do have solar panel implementation in our next generation eKo Pro series products that can deliver battery life of over 5 years.

"Gallery” by Stanza, is a dynamic public sculpture viewable over the internet.

“Gallery” by Stanza, is a dynamic public sculpture viewable over the internet. Gallery describes the space, in this case the upper gallery in Plymouth Arts Centre, England. Made during an artist in residency project in situ in the gallery space during feb 2008.

The gallery interior has been made virtual and placed online. “Gallery”, is part of a series of process led experiments in data visualization within the context on an art gallery. This is an experimental engagement with data in the art gallery using sensors and CCTV. Stanza asks , “what happens during the process of visiting the gallery as a dataspace”; ie what happens to the gallery and what do the visitor do?

The sensors are used as real time recording devices to gather information about the sensory behaviour of the real space. The gallery becomes the artwork formed by the emergent real time data in the space.
The gallery laid bare as a work of art. Gallery proposes that the data is art. The art is a real time flow of the things around us that allow our senses to invoke understanding. The gallery space becomes the art described by the shifts in light, temperature and noises in the space over time.
