BOM lab residency week three

Last week I got back on it after having been distracted by other things. I came up with a plan which is to record a load of sounds and air quality readings from where those sounds were recorded and then group all the clean and dirty sounds together and make music out of them. I also came up with an idea about how to present the work in an installation context that links these sounds and ideas back to the body and breathing. My observations from the first sensor I built were that the particulates in the air peak with human activity and then drop of exponentially. This tallies with what I’ve read, basically we kick up dust when we walk about places indoors. I’ve decided to do something that’ll respond to people in the space that will kick up loads of particles from the floor when they walk in. For a while now I’ve wanted to build an interactive installation that rewards people standing very still so I’m going to make it play one kind of music when the dust settles and draw from the other set of sounds when people move round.


I ordered a brand new knock off Arduino, an SD card logger, another sensor and a portable microphone and found somewhere to get some acrylic laser cut to make a nice box. The idea is to build a hand held sensor box I can take out outdoor places with my field recorder and a second box I can leave indoor places to surreptitiously record ambient sounds and air quality stats. I did look at the cost of just buying a sensor but building my own worked out significantly cheaper and more fun. While I’m waiting for the bits to arrive I’ve been studying ways to passively monitor people’s breathing rate using Eulerian Video Magnification and got something working in OpenFrameworks.

Field recording DSC_2549

Despite not having my box built yet I decided to go out and make some field recordings and take some pictures anyway. I got back on the music front and boshed this out. I made the whooshy bass line and bits of percussion for this track out of the sound of my daily train commute to Birmingham, the air humming by the window and some bloke coughing. Quite ambient….. could be even more ambient…. you have to limber up for full ambience though.

BOM Lab residency week two

This week was mostly eaten up by revising a piece of work I had hoped to hand over before I left for Birmingham, though I did have a meeting with an air quality scientist from the University of Birmingham and I am hopeful that the scene has been set for a meaningful art science collaboration to take place.


The piece that I spent the week re-work was from Diagramming the Archive and used the PRONI‘s archive of signatures of the Ulster Covenant. The curator’s brief involved layering the images to give a sense of the mass of inscriptions that were collected. Initially I had tried to inject some movement and perspective into this by selecting images at random and layering them in space. I had wanted to do this from four simultaneous camera angles using different projection methods but when I came to port my code to openFrameworks on the raspberry pi 3 the necessary grunt wasn’t there. layered covenants 4 camera angles

In the end I had settled on a single camera angle and selected images at random allowing them to fade in, move across the frame and fade out again.


But the effect was all a bit slideshow so I went back and constructed another of other studies. They all involved layering in different ways and looking at the density of inscriptions, one involved taking the dense parts and using that as starting point for geometric drawing algorithms and the others just averaged large sets of images to give a feel of the archive as a whole and would potentially use that as the starting point for something else.

geometric drawing Mass averaging of images

At one point I started drawing images from the archive in to my computer having forgotten to clear the memory from the buffer I was writing to and got some really nice glitch effects going on based on the left over imagery my graphics card had previously been drawing.


Given the archive images I had been supplied with already had a number of glitches within them, presumably artefacts of the scanning and compression processes I decided to base the aesthetic of the work around that, sitting next to Antonio Roberts at BOM Lab probably helped inspire me in this direction.

Unfortunately the background buffer would not glitch on the pi in the same way as OS X so I ended up creating the backdrop images on my mac and using them as a backdrop for the layered texts. This made me think that as I now had a free hand to import whatever images I want into the backdrop, not just things that had previously been on my mac’s screen (the first glitches were just copies of the XCode screen before my app started working) I should perhaps think about what imagery would make the most sense in the work. To me the glitch aesthetic immediately situated the work in the present so I started to think about how James Craig might go about galvanising support for his cause if the situation played out again.  I created mockups of the Covenant text on modern petition websites and then glitched those to use as the back drops. To further give a sense of this conflation of real past events and how it might be approached in the present I animated lots of mouse pointers scanning across the text as if they were signing it.

mock up final piece

The curator had stipulated my piece had to link up wirelessly with Ed & George‘s drawing machine which had been commissioned to create imagery based on the same set of images and we had struggled for a long time to find a meaningful way of linking them that was obvious to an audience but not just inserted purely for its own sake. The recurring problem was that their machine moves very slowly to create its artwork while my screen based work could move at a much faster pace. We also quite liked that contrast between them so slowing mine down to their speed seemed wrong. I had decided to make my pointers, symbolising the people signing the petition, beachball whenever the work selected new images to layer as a way of further playing with the glitch theme and injecting some humour into the work. We thought it would be fun if while my piece beachballed theirs simultaneously paused too, like the whole installation was temporarily brought to a halt under the weight of loading new imagery from the archive.



You can see the work at  The Irish Architectural Archive, 45 Merrion Square, Dublin (June 1st – 30th) and at The Linen Hall Library, 17 Donegall Square, Belfast, (September 5th – 30th).


Next week I will be mostly working on recording ambient sounds and air quality data.

BOM Lab residency week one

I’ve put my first week in at my residency in Birmingham Open Media Lab. Since I arrived last week I was inducted to the space and had the necessary kitchen and mug politics explained to me. Everyone’s been very friendly and welcoming so I felt quickly at home.

Birmingham Open Media Lab

My project involves using air quality data and field recordings to algorithmically generate ambient music. There’s something in the idea of highlighting something invisible through sound that appeals. Air is the medium for both sound and pollution so in my head the link seems already present. Also ambient, as a genre, seems apposite for writing music about air, they’re both ‘just there’. Slow chord progressions always remind me of breathing. I’m quite keen to explore the idea of working with simultaneously sampling both sound and air quality in the same space and really getting into the idea of air as both a medium for sound and pollution and a subject in itself to compose and make art about.

There’s a danger in work like this that you can fall into the trap of ‘interesting projects’ where you never attain a clarity of purpose around what you’re doing, there’s a really great piece of writing about this phenomenon here (and air quality projects get a mention). As such I’ve spent sometime struggling with the question of what it is I’m trying to achieve and decided that the point is to try and generate work that forces people to re-appraise their relationship with their environment, the effect we have on it and the reciprocal effect it’s having on us.

Quite how the piece will work and how it will be presented is still something I’m mulling over, I’m hoping to put whatever comes out of this 3 month R&D phase into use in various contexts. This week I’ve done some research around other projects that have mapped environmental data to sound or light or just used cheap sensors to sample data.

Erik Guzman’s Weather Beacon

John Eacott’s Floodtide

Matthew Schroyer’s Understanding air pollution with a simple dust sensor

Tony Kauffmann and Nicholas Johnson’s Solar Powered air quality sensor

Air Pi (sadly discontinued)

Citizen science kit. (nice bit of kit but each one costs around £150)

An unnamed Indian child’s homemade air quality monitoring station (he’s got the same sensor as me and did some interesting work souping it up a bit)

This list isn’t exhaustive and I’ll keep adding to it as I research more.

After looking around some of the sensors available for acquiring air quality data I picked up Grove dust sensor and wired it up to a spare Photon that I had handy. I’ve left it running in the gallery at BOM lab the last two days to see if I can get any meaningful data from it.

DSC_2271 very basic air quality sensor

Looking at what I’ve got you can see spikes that correlate with human activity in the space which makes sense, the restaurant BOM lab shares it space with is being refitted which will probably kick up a fair bit of dust. From what I’ve read the sensors only really give qualitative data.

I’m meeting an academic from the university of Birmingham next week who will hopefully help inject some actual meaningful science into my work so that I’m not just mapping noise. Musically little has taken place beyond putting my studio back together in my parent’s house where I’m staying while I work in Birmingham. I’ve got a gig tomorrow which will perhaps help kick start the writing process.

Process Lab / Rehearsal Rooms – Day Five

I left it a few days before writing up our final day in the project space, to let the dust settle (and the talcum powder – sort of an inside joke but one of the previous artists, Shelby Hanna, had recreated a dust storm with a lot of talcum powder and fans – really wish I’d seen it in person). We tried to tie the loose ends together and present the video works alongside the pictures that had been created in their construction and also worked on a final piece that Sharon drew on the wall while I projected data over it. We took a couple of runs at this one and though it was almost an after thought, as Peter had playfully told us to draw on the walls, it was probably the best still image to come out of the process. Working with the eraser on the charcoal and with the scrape marks of previous attempts Sharon was able to create an image which was both representative of the data I had projected and at same time transcendent of it, bringing a lot of herself to it. This was what I had hoped we’d get out of the project at the beginning.

In the afternoon we opened for a couple of hours and got some good feedback, we had a lot to think about where we might take things next. The final piece that used both lines and negative space is something I’d like to work back into my data visualisation and quite how we might animate that is an open question.
