Revision as of 14:50, 24 February 2016

Living Instruments is the tentative title for a collaborative project between London-based musician Serge Vuille (under the umbrella of his project WeSpoke), Hackuarium and the DIYbio community at large.

The final deliverable was a concert/performance that took place on February 10th 2016, at the music and performance art venue Le Bourg, in Lausanne, Switzerland. More information about the event can be found here.

The concert was followed by a workshop/masterclass at the Lift conference on innovation and digital technologies in Geneva, Switzerland, on February 12th 2016. More information about the workshop can be found here.

What

EN - This collaboration aims at three goals:

  • To built a set of living instruments that use biological information or organisms as sources of signal.
  • To compose a musical piece (creation) using these instrument and turning their output signal into sound
  • Place this project in the context of the current state of DIY, science and music

FR - Cette collaboration a trois buts:

  • Construire des instruments vivants (intégrant le vivant comme source de signal)
  • Création d'une œuvre musicale (composition) en utilisant ces instruments
  • Placer la démarche collaborative dans le contexte DIY, scientifique, et musical


Who is involved?

  • Serge Vuille, musician
  • Vanesa Lorenzo, interactive designer
  • Luc Henry, biologist and science communicator
  • Robert Torche, sound designer
  • Oliver Keller, electronics and IT specialist
  • We Spoke musicians


When

EN - The concert was scheduled on February 10th 2016, at Le Bourg, Lausanne.
FR - Le concert a eu lieu le 10 février 2016, au Bourg, Lausanne.

What?

Paramecia tracking device:

After several prototypes, the SeePack microscope camera was replaced by a Logitech C270. The device was built according to previously described design (instruction video here) except the bottom acrylic glass plate was kept intact (with a piece of dark paper underneath). A rubber joint was also added between the two acrylic glass plates (see picture below).

The joystick was the Play-Zone Arduino PS2.

Urs from GaudiLabs has also described a similar module (instruction video here).

Building the modules

Wiring:

The whole system was wired using twisted-pair cables from Ethernet cables.

To avoid confusion, the 4 types of components were wired using a colour code (see picture below).

A
Colour code used for wiring.

Fermentation cultures:

We used pure brewing yeast cultures growing in YPD medium and feeding on glucose to produce CO2 gas:

  • Starting from 2mL dense culture (from overnight growth from plate) in 250 mL fresh medium.
  • The next day, the dense culture were complemented with 50 mL of 40% glucose solution (not sterile) -> 8% final glucose concentration.
  • The cultures started producing CO2 after 30 min (2 mL CO2 per minute)
  • The cultures could be used after 90 minutes (5 mL CO2 per minute)

Bubble sensors:

Bubble sensors we built using a white LED and a photodiode. The setup was inserted in a wooden clothespin.

A
Prototype of the bubble sensor before wiring.
A
Scheme of light sensor clip wiring for testing.

An option for the calibration of the sensors was explored based on a tutorial proposed by Arduino.

Microphones:

Microphone/Headphone Amplifier Stereo DIY kit (MK136, Velleman) were purchased from Distrelec and build according to instructions.

Paramecia tracking device:

SeePack microscope camera (see picture below) was mounted on our Carl Zeiss Axiolab E re microscope.

The EasyCapViewer 0.6.2 software was used as a player to record live images.

Mossphone:

Brainstorming Session

We spent those three days brainstorming at UniverCité, trying to design 'instruments' that we could play, based on fermenting yeast cultures.

The 'instruments' we envisage would be driven by living organisms that produce work we can turn into sound. The most obvious example is fermentation (microorganisms eating glucose and rejecting alcohol and CO2) producing a gas that one can use to make bubbles, sounds, etc.

These instruments can fall into 3 categories:

LIVE - AUTONOMOUS AND COMPUTER INTERACTION No need for a human being to work in order to produce a sound from the living organisms activity.

  • Gas producing fermentation broth (Bacteria and yeast) and gas-machine interactions
  • Insects (moths, fruit flies) movement recognition software

LIVE - HUMAN INTERACTION A human subject will read a score written by living organisms and play an 'instrument' according to this score

  • Keyboard and microscopic score -> observe microorganisms in water from local pond -> organisms move in microscope field on "score" slide

RECORDED - COMPUTER INTERACTION A recorded signal from an organism is used as a score and played either directly by a computer or by a human subject.

  • Using for example genomic data (from the organisms used in other 'instruments') to generate sound. This could be simple (ATGC into tunes) or complex (use of amino acids triplex).

Building the first prototype

Together with Serge Vuille, our musician in residence, we designed and built a series of living instrument prototypes.

(Thanks biodesign.cc for the soldering iron!)

Overview of the prototype:

Before we go into too much details, you can check the video!

Now a bit more details. Below you find a picture of the setting, the recipe to produce CO2 from yeast fermentation and a scheme of the bubble detector device.

Tubing set-up:

A. is the 250mL yeast culture producing the CO2.
B. is the electronic circuit that allows our Arduino UNO board to make a variable sound when gas bubbles are going through the glass tube filled with ink-coloured water.
C. is simply a photodiode that will sense white light (from white LEDs) when the bubbles pass by.

A
This is what the whole setup looks like.

Fermentation cultures:

We used two different types of cultures to produce CO2 gas:

As a test, we used random culture from rotting fruits juice.

  • Blackberries were squashed into a juice and diluted with 1/5 water (40 mL into 160 mL) and the mixture stirred at room temperature. There was an immediate production of CO2 gas.


A
This was the first prototype of bubbler using fermenting blackberries.


To get something more reproducible, we used pure brewing yeast cultures feeding on glucose.

  • The composition of the overnight medium was as follow: 2.5g YE, 5g Peptone, 5g glucose in 250mL dd water ->sterilised in autoclave
  • Starting from 2mL dense culture (from overnight growth) in 200 mL fresh medium, the optical density after 5 hours was 0.81 (closed vial) and 0.74 (open vial). The next morning it was 2.75 in open vial at 31°C and 2.89 in closed vial at 25°C.
  • We added 50 mL of 40% glucose solution (not sterile) -> 8% final glucose concentration.
  • The cultures started producing CO2 after 10 minutes.


A
This was the second prototype using yeast culture to produce CO2 gas in a balloon. Before. After.


Arduino bubble detector:

The blueprint is simple: if a bubble passes through the tube and crosses the path between the photodiode and the white LEDs, it makes a sound (green and black speaker). The pitch depends on the light intensity.

The code is coming up on Github.

This is the circuit in real.
