Some preparations for the implementation of the tryptic

  • Succour
  • KRA.LAND: (StudioAsOrganizm + Tubeland 2019-22)


In this section we are developing the blueprints for an instrument to measure the basic properties of sunlight, CO2 amounts, additional environmental information, air particles and other polutions.

For the moment we are looking into building a cheap and accurate mobile/portable device, and start working with data acquisition. This is the necessary technical part.

References, instructables:

In a second section the historical and contemporary cultural-artistic references will be commented.

In a third section the building up the 1-year installation is to be documented in its progress.

Additionally collaborations and references will be added. For the moment we are reading into the physics of light that is producing matter, land use and geo engineering issues. Soon a lot more about this all here…

current support


There are some explanations available online, that can function as an update to your basic knowledge of physcs:

If we want to acquire data we have to look into sensors that track the basic components of sunlight

 sunlight = 
 1 UV light <0.8µm
 2 infrared radiation >0.4µm
 3 visible light <0.4-0.8µm>

There are also quite some phenomena that we can look into:

  • refraction of sunlight
  • absorbation: carbon, water, ozone filter, air molecules and dust particles
  • blue light = more scattered light than red wavelengths

Of interest is the idea that all flora + fauna are influenced by a simple formula:

 DayLength + CO2 = geological layers formed by it? 


  • the energy in wind comes from the sun, so do the colours of skies and clouds
  • as a side-project, we can look into katabatics: air is moving faster around the poles
  • technically antarctica is a desert, very dry!

Idea development in 7 chapters

  1. scientist technicians artist content exchange meetings interviews cultural references – start with raymond roussel 'locus solus' and a quote…
  2. solar panels and batteries, turn off and start up control of all equipment
  3. IOT sensors in front of the windows, can be all different depending on position and function
    from small to big data, fast and slow, whatever fits or not
    at the receiver end machine learning to make models out of this over 1 year time
  4. sonification: basically we want to bring out the infrared, visible light, UV (bass, mid, high)
    then during the day the colour of the environment (air, clouds) may change due to the atmosphere
    [finally related is also wind and cloud fluctuations, temperature, humidity, ozone and air particles also? but I don't want to make a conventional weather station]
    IOT and machine learning for making sense of the massive amount of incoming data (see 2)
    sonification on the sample level, analogue in referential lengths (bass, mid, high)
    what is the sound of the sun (can only be heard on earth)
    closest to nature = theremin? but with combinatorial oscillations like OMSynth and new synthesis with NSynth
    so, either javascript, python (ML libraries like TensorFlow, Scikit, Theano, Matplotlib, Seaborn, etc.. for Python or TensorFlow.js, Brain.js, Convent.js, Webdnn, Deeplearnjs, Compromise, ml.js etc for Javascript)
    or puredata (ml-lib), or supercollider (see:
  5. visualisation of 1 year of data, but also of remarkable events/combinations/activities resulting
    maybe the geological layers are interesting as a constant building up of soil defined by sun and wind
    I would be in favour to work with small battery operated cheap lcd screens
  6. spatiality sound: either ambisonics, on each level 8 speakers, bottom floor 4x subs, but that is so classic
    so better: fm transmitted into headphones, radioreceivers, phones, internet…
    spatially defined according to the place of the visitor in the building
    areas of sending and receiving sound with Tetsuo Kogawa's FM transmitters

method for 2019

 monthly meetings with specific subthemes, inviting each time another expert \\
 monthly work sessions, inviting experts with necessary technical skills \\


  • Pyranometer: for measurement of global solar radiation
  • Albedometer: for measurement of solar radiation and reflection
  • Pyrheliometer: for measurement of direct solar radiation
  • Pyrgeometer: for measurement of infra red radiation
  • Net radiometer: for measurement of radiation balance


The oldest principle seems to be measuring the temperature of a white and black ring in the sunlight. But nowadays there seem to be a lot of materials and designs for experimenting and making DIY measure tools.

Using an Arduino or Raspberry pi, the following ready to make designs are online available:

Other electronic components for extending the sunlight measurements

Tetsuo Kogawa (FM transmitters)

Light to Frequency Converter - TSL235R


Other sensors


color recognition TCS3200

infrared detection

CO2 sensors – MQ 135 (may be too inaccurate)

ozone sensors

dust particles


BME280 I2C or SPI Temperature Humidity Pressure Sensor

more partially interesting things (interesting combination UV gas temp/hum)

cloud sensor (expensive)

solar operated rpi

First test and introduction: RPI sunlight sensing project

… and if we need to add a weather station (wind dir/speed temp hum barometer CO2 particles) expand use maybe a peer-to-peer network with arduinos and raspberry pis and a homeserver? (ask gepeto and dom)

the future is as speculative as the past?

expand the 'studio as organizm (Kra-Sao)' and the Tube-Observatory with mobile units (to be placed in several places):

  • sun (light, colour) and wind (air flow)
  • ozone, CO2 and particles
  • weather station temperature, humidity, barometer, …
  • garden and water kits
  • data home server
  • indoor sonification ambisonics 7.1
  • outdoor solar amps multichannel
  • FM transmissions
