==Original Idea==

At first this project should have been about “Perception of Time”. We live in an age where time appears to have become more precious, yet everything has to be at a faster pace. This is not just for the last few years, but since the beginning of the industrialisation. In big cities, but also in the digital world you see most of the people rushing. On the internet, for instance, videos become shorter, because people often don’t want to take the time to watch much longer content anymore.

==New Idea==
In the later experiments this concept broke down to abstract experiments with physics, which turned out to be more captivating than the preliminary idea. A clear image/sequence is projected on the wall that is moving slowly or even static. The more crowded a room becomes the more turbulent the video will turn and eventually end up in an abstract waveform that is separated in the colour spectrum of the projector. It can be seen as a physical destruction of the light or the digital image. At the same time, the speaker that brings the mirror to vibrate becomes louder and more tense and eventually ends up in a wild and tempestuous soundscape.

==Initial Experiment==

In my first experiment I stumbled upon an effect that was created by a mirror film reflecting a white logo projected on it. Then the image was distorted, almost shattered by a speaker that was vibrating the mirror film.

[[:File:EwP_Experiment1.mp4]]

==Material Studies==

To make the image clearer, for the next experiments static mirrors were used. These were vibrated by an audio exciter, which is a speaker that is resonating a solid material to create sound, that is attached to the backside mirror. To get the best out of it, different materials were tested with different speakers and different projectors.

[[File:EwP_DLP.jpg|400px]]

===DLP Projector===
Unless a LED or LCD projector, a DLP projector uses a color wheel that spins in a RGBW pattern, so fast, that the human eye thinks it’s seeing a distinct image. This technology allows to break up the colours of the projected light.

[[File:EwP_ExciterSpeaker.jpg|400px]]

===Exciter Speaker / Bodyshaker===
An exiter is a speaker that needs to be
used on solid surfaces to resonate them.
Cannot be used with mirror film, so it is
not being used in this project

==Further Experiments==
These were experiments with an LCD
Projector and mirror and mirror film, that
were vibrated by an exciter speaker.
Further experiments included different
projectors, different materials for the
mirror, different speakers and the decision
what to project and distort.

Result with DLP Projector and Mirror
{{#ev:vimeo|709927445|Experiment Result}}

==Aesthetics==

Not only the projection, but the contraption will be a sculpture on it’s own. In the next step I will try to convert the speaker in the box to just a flat surface of mirror film, that is hanging in the room. I will try to build a speaker and use the foil as a membrane, so that it vibrates itself. The projected image will be a totally abstract, the distortion of the grid in this case looks very organic and the lines blur into one another the stronger the trigger becomes.

==Trigger==

To trigger the installation, three ways are compared and then the best and easiest will be used.

===WiFi Device Detector===
The first one is a WiFi-Device-Counter, that can detect how many devices like smartphones are located in a room. This way of counting people could back the idea of people diving deeply into the digital world where everything is overly fast paced. I tried it, it worked fairly well, but I soon understood that it would either be misunderstood or not recognised at all without additional explanation.

[[File:EwP_WiFiSniffer.jpg|400px]]

===Second floor with transducers===
In the second approach to trigger the installation, transducers installed underneath a second floor would be an option. These could be used for example to capture the vibration, that can easily be converted into a vibration on the speaker again. For capturing, multiple cheap piezos could be used as contact microphones. This option might be too bulky and is more difficult to install.

[[File:piezo3.jpg|400px]]

===Noise in the room===
The easiest to install and perhaps the most obvious way is to install microphones all over the room and measuring the amplitude of those. With these data the amplitude of a low frequency sine wave can be controlled and eventually regulates the strength of the vibration of the mirror.

[[File:EwP_Microphone.jpg|400px]]

===Microphone amplitude – Processing Code===
This code is generating the projected image, capturing the amplitude
of the microphone and playing the sound to the speaker.

<source style="border:none; height:650px; overflow:scroll;" lang="c" line start="55" highlight="4">
import processing.sound.*;

AudioIn input;
Amplitude analyzer;
SinOsc sine;
int gridScale = 45;
int columns, rows;

void setup() {

//VISUALS:

//Start grid in fullscreen on second screen with black background
fullScreen(2);
background(0);
//Initialize columns and rows
columns = width/gridScale;
rows = height/gridScale/2;

//AUDIO:

//Start listening to the microphone
//Create an audio input and grab the 1st audio channel
input = new AudioIn(this, 0);
//Start the audio input
input.start();
//Create a new amplitude analyzer
analyzer = new Amplitude(this);
//Patch the input to an volume analyzer
analyzer.input(input);
//Create sinewave
sine = new SinOsc(this);
}

void draw() {

//VISUALS:

//Begin for-loop for columns
for (int i = 0; i < columns; i++) {
//Begin for-loop for rows
for (int j = 0; j < rows; j++) {

// Scaling up to draw a rectangle (x,y)
int x = i*gridScale;
int y = j*gridScale;
//Fill the rectangle with black and give it a white stroke
fill(0);
stroke(255);
strokeWeight(3);
//For every column and row, a rectangle is drawn at an x and y location
rect(x, y, gridScale, gridScale);
}
}

//AUDIO:

//Get the overall volume (between 0 and 1.0)
float vol = analyzer.analyze();
//Map volume to sinewave volume
float vol1 = map(vol, 0, 0.5, 0, 1);
//Play sinewave with frequency of 60Hz and the volume mapped to the amplitude of the microphone
sine.amp(vol1);
sine.play();
sine.freq(60);
delay(100);
}
</source>

==Next Steps==

*Build the contraption and test it in a few iterations
*Try all the solutions for the trigger and build the final one
*Think about the projected imagery? Maybe generate something, but it should stay very abstract.
*Find a better surface than a wall to project it on. A slightly frosted glass shield could create the illusion of a holograph.
*Test it in a larger scale (maybe with audience)
*Get a better understanding of the science behind it to make minor improvements

A large mirror film mounted to a wall begins to vibrate in the motion of waves. The mirror reflects a different distorted image of yourself and the room you are in. It creates a feeling of dizziness.

GMU:Observe - Experiment - Connect

2022-05-14T22:03:13Z

Krewern: /* Students Project Outlines */

[[File:TITEL.jpg|1000px]]
----
"'''observe - experment - connect'''" are the strategies employed to set aesthetic artifacts and artistic measures on the way.
'''Observation''' precedes every creative practice; it can still happen with one's own senses, but also with sensors or prepared data collections. '''Experience''' marks the second stage, in which a processing of these collected impressions takes place. This stage, in which experimentation plays an essential role, is followed by a '''Contact Scenario''' with an environment.
In the project we center artistic-creative activity around forms of an expanded ecology: the ecology of the natural environment, the ecology of the subject, and the ecology of the social. In observing, experimenting and situational, medial connecting we will try out and evaluate creative ways of acting in a shared habitat (the theme of previous semester projects).
In the module we want to produce construction kits, sample catalogs, installations, manuals, recipes, actions, apparatuses, game plans or other forms of proposals that help to make our civilization ecological, open and connectable.

----
"observe - experment - connect" seien die Strategien, mit welchen aesthetische Artefakte und Maßnahmen auf den Weg gebracht werden.
'''Beobachten''' geht jeder gestalterischen Praxis voraus, sie kann noch mit den eigenen Sinnen, aber auch mit Sensoren oder Datensammlungen passieren. '''Experience''' markiert das zweite Stadium, in welchem eine Verarbeitung dieser gesammelten Eindrücke erfolgt. Auf dieses Stadium, in welchem das Experimentieren eine wesentliche Rolle spielt, folgt ein Szenario des I'''n-Kontakt-Tretens''' mit einem Umfeld.
Im Projekt orientieren wir künstlerisch-gestalterisches Handeln an Formen einer erweiterten Ökologie: der Ökologie der natürlichen Umgebung, der Ökologie der Subjekte und der Ökologie des Sozialen. Im Beobachten Experimentieren und situativem, medialem Verbinden werden gestalterische Handlungsweisen in einem geteilten Habitat (dem Thema früherer Semesterprojekte) ausprobiert und evaluiert.
Im Modul wollen wir Baukästen, Musterkataloge, Installationen, Handbücher, Rezepte, Aktionen, Apparate, Spielpläne oder andere Formen von Vorschlägen produzieren, welche helfen, unsere Zivilisation ökologisch, offen und anschlußfähig zu gestalten.
----
The module builds on the presentation on media art provided by Ursula Damm. Acces through Moodle or Cloud.
----
Meetings in April online - please contact for LINK ursula.damm at uni-weimar.de
Meetings with the beginning of May alternating virtual and in presence at the Digital Bauhaus Lab Bauhaus Strasse 7, ground floor.

During the semester we will focus on the topics
* CONSTRUCTION-DESTRUCTION (to address the current situation)
* ARTIFICIAL INTELLIGENCE (to establish the cooperation with Alexander König)
* LICHEN (to continue our long-term group project, here our online resources [https://drive.google.com/drive/folders/1-nut9Yd3m1ViGX9qXG9TI58fN3xvNfRG google drive])

==Original Idea==

At first this project should have been about “Perception of Time”. We live in an age where time appears to have become more precious, yet everything has to be at a faster pace. This is not just for the last few years, but since the beginning of the industrialisation. In big cities, but also in the digital world you see most of the people rushing. On the internet, for instance, videos become shorter, because people often don’t want to take the time to watch much longer content anymore.

==New Idea==
In the later experiments this concept broke down to abstract experiments with physics, which turned out to be more captivating than the preliminary idea. A clear image/sequence is projected on the wall that is moving slowly or even static. The more crowded a room becomes the more turbulent the video will turn and eventually end up in an abstract waveform that is separated in the colour spectrum of the projector. It can be seen as a physical destruction of the light or the digital image. At the same time, the speaker that brings the mirror to vibrate becomes louder and more tense and eventually ends up in a wild and tempestuous soundscape.

==Initial Experiment==

In my first experiment I stumbled upon an effect that was created by a mirror film reflecting a white logo projected on it. Then the image was distorted, almost shattered by a speaker that was vibrating the mirror film.

[[:File:EwP_Experiment1.mp4]]

==Material Studies==

To make the image clearer, for the next experiments static mirrors were used. These were vibrated by an audio exciter, which is a speaker that is resonating a solid material to create sound, that is attached to the backside mirror. To get the best out of it, different materials were tested with different speakers and different projectors.

===DLP Projector===
Unless a LED or LCD projector, a DLP projector uses a color wheel that spins in a RGBW pattern, so fast, that the human eye thinks it’s seeing a distinct image. This technology allows to break up the colours of the projected light.

[[File:EwP_ExciterSpeaker.jpg|400px]]

===Exciter Speaker / Bodyshaker===
An exiter is a speaker that needs to be
used on solid surfaces to resonate them.
Cannot be used with mirror film, so it is
not being used in this project

==Further Experiments==
These were experiments with an LCD
Projector and mirror and mirror film, that
were vibrated by an exciter speaker.
Further experiments included different
projectors, different materials for the
mirror, different speakers and the decision
what to project and distort.

==Aesthetics==

Not only the projection, but the contraption will be a sculpture on it’s own. In the next step I will try to convert the speaker in the box to just a flat surface of mirror film, that is hanging in the room. I will try to build a speaker and use the foil as a membrane, so that it vibrates itself. The projected image will be a totally abstract, the distortion of the grid in this case looks very organic and the lines blur into one another the stronger the trigger becomes.

==Trigger==

To trigger the installation, three ways are compared and then the best and easiest will be used.

===WiFi Device Detector===
The first one is a WiFi-Device-Counter, that can detect how many devices like smartphones are located in a room. This way of counting people could back the idea of people diving deeply into the digital world where everything is overly fast paced. I tried it, it worked fairly well, but I soon understood that it would either be misunderstood or not recognised at all without additional explanation.

[[File:EwP_WiFiSniffer.jpg|400px]]

===Second floor with transducers===
In the second approach to trigger the installation, transducers installed underneath a second floor would be an option. These could be used for example to capture the vibration, that can easily be converted into a vibration on the speaker again. For capturing, multiple cheap piezos could be used as contact microphones. This option might be too bulky and is more difficult to install.

[[File:piezo3.jpg|400px]]

===Noise in the room===
The easiest to install and perhaps the most obvious way is to install microphones all over the room and measuring the amplitude of those. With these data the amplitude of a low frequency sine wave can be controlled and eventually regulates the strength of the vibration of the mirror.

[[File:EwP_Microphone.jpg|400px]]

===Microphone amplitude – Processing Code===
This code is generating the projected image, capturing the amplitude
of the microphone and playing the sound to the speaker.

int columns, rows;

//Patch the input to an volume analyzer

}

void draw() {

// Scaling up to draw a rectangle (x,y)
int x = i*gridScale;
int y = j*gridScale;
//Fill the rectangle with black and give it a white stroke
fill(0);
stroke(255);
strokeWeight(3);
//For every column and row, a rectangle is drawn at an x and y location
rect(x, y, gridScale, gridScale);
}
}

//AUDIO:

//Get the overall volume (between 0 and 1.0)
float vol = analyzer.analyze();
//Map volume to sinewave volume
float vol1 = map(vol, 0, 0.5, 0, 1);
//Play sinewave with frequency of 60Hz and the volume mapped to the amplitude of the microphone
sine.amp(vol1);
sine.play();
sine.freq(60);
delay(100);
}
</source>

==Next Steps==

*Build the contraption and test it in a few iterations
*Try all the solutions for the trigger and build the final one
*Think about the projected imagery? Maybe generate something, but it should stay very abstract.
*Find a better surface than a wall to project it on. A slightly frosted glass shield could create the illusion of a holograph.
*Test it in a larger scale (maybe with audience)
*Get a better understanding of the science behind it to make minor improvements

Krewern: /* Projection and Perspective */

[[File:Shared Habitat Doku_Page_01.png|800px]]

==Original Idea==

At first this project should have been about “Perception of Time”. We live in an age where time appears to have become more precious, yet everything has to be at a faster pace. This is not just for the last few years, but since the beginning of the industrialisation. In big cities, but also in the digital world you see most of the people rushing. On the internet, for instance, videos become shorter, because people often don’t want to take the time to watch much longer content anymore.

==New Idea==
In the later experiments this concept broke down to abstract experiments with physics, which turned out to be more captivating than the preliminary idea. A clear image/sequence is projected on the wall that is moving slowly or even static. The more crowded a room becomes the more turbulent the video will turn and eventually end up in an abstract waveform that is separated in the colour spectrum of the projector. It can be seen as a physical destruction of the light or the digital image. At the same time, the speaker that brings the mirror to vibrate becomes louder and more tense and eventually ends up in a wild and tempestuous soundscape.

==Initial Experiment==

In my first experiment I stumbled upon an effect that was created by a mirror film reflecting a white logo projected on it. Then the image was distorted, almost shattered by a speaker that was vibrating the mirror film.

[[:File:EwP_Experiment1.mp4]]

==Material Studies==

To make the image clearer, for the next experiments static mirrors were used. These were vibrated by an audio exciter, which is a speaker that is resonating a solid material to create sound, that is attached to the backside mirror. To get the best out of it, different materials were tested with different speakers and different projectors.

This is not just for the last few years, but since the beginning of the industrialisation. In big cities, but also in the digital world you see most of the people rushing. On the internet, for instance, videos become shorter, because people often don’t want to take the time to watch much longer content anymore.

==New Idea==
In the later experiments this concept broke down to abstract experiments with physics, which turned out to be more captivating than the preliminary idea. A clear image/sequence is projected on the wall that is moving slowly or even static. The more crowded a room becomes the more turbulent the video will turn and eventually end up in an abstract waveform that is separated in the colour spectrum of the projector. It can be seen as a physical destruction of the light or the digital image. At the same time, the speaker that brings the mirror to vibrate becomes louder and more tense and eventually ends up in a wild and tempestuous soundscape.

==Initial Experiment==

In my first experiment I stumbled upon an effect that was created by a mirror film reflecting a white logo projected on it. Then the image was distorted, almost shattered by a speaker that was vibrating the mirror film.

[[:File:EwP_Experiment1.mp4]]

==Material Studies==

To make the image clearer, for the next experiments static mirrors were used. These were vibrated by an audio exciter, which is a speaker that is resonating a solid material to create sound, that is attached to the backside mirror. To get the best out of it, different materials were tested with different speakers and different projectors.

[[File:EwP_DLP.jpg|400px]]
DLP Projector
Unless a LED or LCD projector, a DLP projector uses a color wheel that spins in a RGBW pattern, so fast, that the human eye thinks it’s seeing a distinct image. This technology allows to break up the colours of the projected light.

[[File:EwP_ExciterSpeaker.jpg|400px]]
Exciter Speaker / Bodyshaker
An exiter is a speaker that needs to be
used on solid surfaces to resonate them.
Cannot be used with mirror film, so it is
not being used in this project

==Further Experiments==
These were experiments with an LCD
Projector and mirror and mirror film, that
were vibrated by an exciter speaker.
Further experiments included different
projectors, different materials for the
mirror, different speakers and the decision
what to project and distort.

==Aesthetics==

Not only the projection, but the contraption will be a sculpture on it’s own. In the next step I will try to convert the speaker in the box to just a flat surface of mirror film, that is hanging in the room. I will try to build a speaker and use the foil as a membrane, so that it vibrates itself. The projected image will be a totally abstract, the distortion of the grid in this case looks very organic and the lines blur into one another the stronger the trigger becomes.

File:EwP_Render2.jpg
</gallery>

==Trigger==

To trigger the installation, three ways are compared and then the best and easiest will be used.

===WiFi Device Detector===
The first one is a WiFi-Device-Counter, that can detect how many devices like smartphones are located in a room. This way of counting people could back the idea of people diving deeply into the digital world where everything is overly fast paced. I tried it, it worked fairly well, but I soon understood that it would either be misunderstood or not recognised at all without additional explanation.
[[File:EwP_WiFiSniffer.jpg|400px]]

===Second floor with transducers===
In the second approach to trigger the installation, transducers installed underneath a second floor would be an option. These could be used for example to capture the vibration, that can easily be converted into a vibration on the speaker again. For capturing, multiple cheap piezos could be used as contact microphones. This option might be too bulky and is more difficult to install.
[[File:piezo3.jpg|400px]]

===Noise in the room===
The easiest to install and perhaps the most obvious way is to install microphones all over the room and measuring the amplitude of those. With these data the amplitude of a low frequency sine wave can be controlled and eventually regulates the strength of the vibration of the mirror.
[[File:EwP_Microphone.jpg|400px]]

===Microphone amplitude – Processing Code===
This code is generating the projected image, capturing the amplitude
of the microphone and playing the sound to the speaker.

<source style="border:none; height:650px; overflow:scroll;" lang="c" line start="55" highlight="4">
import processing.sound.*;

AudioIn input;
Amplitude analyzer;
SinOsc sine;
int gridScale = 45;
int columns, rows;

void setup() {

//VISUALS:

//Start grid in fullscreen on second screen with black background
fullScreen(2);
background(0);
//Initialize columns and rows
columns = width/gridScale;
rows = height/gridScale/2;

//AUDIO:

//Start listening to the microphone
//Create an audio input and grab the 1st audio channel
input = new AudioIn(this, 0);
//Start the audio input
input.start();
//Create a new amplitude analyzer
analyzer = new Amplitude(this);
//Patch the input to an volume analyzer
analyzer.input(input);
//Create sinewave
sine = new SinOsc(this);
}

void draw() {

//VISUALS:

//Begin for-loop for columns
for (int i = 0; i < columns; i++) {
//Begin for-loop for rows
for (int j = 0; j < rows; j++) {

// Scaling up to draw a rectangle (x,y)
int x = i*gridScale;
int y = j*gridScale;
//Fill the rectangle with black and give it a white stroke
fill(0);
stroke(255);
strokeWeight(3);
//For every column and row, a rectangle is drawn at an x and y location
rect(x, y, gridScale, gridScale);
}
}

//AUDIO:

//Get the overall volume (between 0 and 1.0)
float vol = analyzer.analyze();
//Map volume to sinewave volume
float vol1 = map(vol, 0, 0.5, 0, 1);
//Play sinewave with frequency of 60Hz and the volume mapped to the amplitude of the microphone
sine.amp(vol1);
sine.play();
sine.freq(60);
delay(100);
}
</source>

==Next Steps==

*Build the contraption and test it in a few iterations
*Try all the solutions for the trigger and build the final one
*Think about the projected imagery? Maybe generate something, but it should stay very abstract.
*Find a better surface than a wall to project it on. A slightly frosted glass shield could create the illusion of a holograph.
*Test it in a larger scale (maybe with audience)
*Get a better understanding of the science behind it to make minor improvements

=Make it better!=

===Concept===
Can we create a better version? With technological progress humans aim to make everything better, either by designing “add-ons” or by making an artificial copy of something and then changing it to their needs. Artificial intelligence and machine learning is used to execute tasks faster and better than a human being. But is this true and can this be projected on other life forms? Can a man-made machine even understand the behaviour of a natural organism or can it even pursue common tasks and interactions? If behavioural structures can be predicted, it might be a way to experiment with organisms in an ethically acceptable way. And a machine doesn’t become exhausted as quick as an organic life form. But does this really justify it’s “raison d’être”/existence?

===Technical solution===
A deep learning framework will be fed with pre recorded video data and track the organisms (either daphnia or nematodes) behaviour. The recordings are capturing the organism in many different situations and with several impacts on it to give the AI sufficient information about it. If this step is proceeded a simulation of the used organism will be created from the data given, based on the predictions the computer makes. In an installation a projection of both, the real organism and the artificial organism will be opposed. Can a big difference be observed?

===Conclusion===
Can you see glitches, etc.? It would rather be nice to see a failure of the machine, to acknowledge that a natural being cannot be substituted by humans, just to create something for their preferences, but not the ones nature has given us.

"'''observe - experment - connect'''" are the strategies employed to set aesthetic artifacts and artistic measures on the way.
'''Observation''' precedes every creative practice; it can still happen with one's own senses, but also with sensors or prepared data collections. '''Experience''' marks the second stage, in which a processing of these collected impressions takes place. This stage, in which experimentation plays an essential role, is followed by a '''Contact Scenario''' with an environment.
In the project we center artistic-creative activity around forms of an expanded ecology: the ecology of the natural environment, the ecology of the subject, and the ecology of the social. In observing, experimenting and situational, medial connecting we will try out and evaluate creative ways of acting in a shared habitat (the theme of previous semester projects).
In the module we want to produce construction kits, sample catalogs, installations, manuals, recipes, actions, apparatuses, game plans or other forms of proposals that help to make our civilization ecological, open and connectable.

='''SELF PLEASURE'''=
===Self Stimulation of Physarum Polycephalum===
----

[[File:SPExp4.JPG|700px]]

==Experiment==

The result of an experiment with Physarum Polycephalum and electricity has shown that it is not only a good conductor, but does produce a very small voltage during its growth. The voltage again is oscillating in the pattern of the plasma flow of the organism. The produced voltage and its resulting oscillation needs to be amplified to be able to be used, then send to an Arduino, where the frequency is calculated. Eventually, the signal is send through Serial into Processing, where the frequency is converted to an auditive frequency that can be played on a speaker and a graph that is shown on a screen. At the end, with an exciter speaker, the audio is fed back to the slime mold, to stimulate it. Like a feedback loop, or a self stimulation it interacts with itself and immediately giving the signal back to the computer.

[[File:SPExp1.JPG|700px]]

This work questions the feelings of organisms such as Physarum Polycephalum and how it perceives stimulation or even pleasure. Although it is stimulating itself, it does not know it does so and did not even give consent. It is a very speculative and philosophical perspective on the world of organisms that have no brain or what we describe as consciousness.

The installation is showing a laboratory setting, where a petri dish is prepared with agar medium and electrodes. The cables lead into a box or machine with a screen that is showing the graph, the aesthetics of the box can be compared to an oscilloscope.
When the slime mould is growing it closes the circuit and the millivolts are produced between the electrodes.

==Instructions to build your own Physarum Sound Generator==

# Prepare a petri dish with agar medium (2%)
## Weigh 100g of distilled water and add 2 grams of agar
## Cook the medium until it will thicken up
## Divide into Petri dishes or other containers that the surface is evenly covered
# Put two electrodes into the agar as long as it is still liquid
# As soon as the agar solidified divide/cut the agar in the middle, so the electrodes have two independent “agar-blobs” and are not in contact
# Now grow your Physarum Polycephalum
## Take two pieces of the dried specimen and use a pipette to put a few drops of water on it.
## Put each of the piece on one electrode.
## Now wait one or two days and be patient
# Meanwhile, build an amplifier, a good one to use is Martin Howse’s OP-amp (instructions) https://www.uni-weimar.de/kunst-und-gestaltung/wiki/images/Martin-howse.pdf
# Connect electrodes to amplifier and then the amplifier to your Arduino
# Connect your Arduino to your computer and upload the “Arduino Source Code” via the ArduinoIDE on your board.

==Old Concept==

In terms of communication the internet has changed everything in our modern age. With cellular connections we are connected to our loved ones whenever and wherever we are. So why shouldn’t other organisms profit from this system? Do we know if there is a demand in the world of others? Or would they maybe even enjoy the freedom to be able to send signals to their peers?

Every organism has a cell communication to sense the environment, even humans do. As we are using a cellular communication to remotely talk to others, the cell communication in this case becomes cellular. In this experiment two or more Physarum Polycephalum(PP) are disconnected and isolated from each other and then reconnected by using an ESP WiFi module.
An electrical voltage is measured from the organisms and then amplified. During the growth of the PP the plasma flow creates an oscillation in the voltage in shape of a sine wave, which can be used to stimulate the other slime mold and vice versa. This allows the two entities to communicate with their own electronic signals through a digital network.

In two separated fish tanks, a natural environment is created and prepared with electrodes to capture the voltage created by the PP. In between, the cables are running together in a machine, which displays the oscillation/pulses sent by each organism, before being sent to the other one.

This installation manifests the urge and exaggeration of communication living beings need and shows that not only humans can be interconnected by digital networks. But it also raises the question whether other organisms can communicate through electronic signals in a digital world.

==First experiments to understand the organism==
I’ve been trying to understand what’s good and what’s not so suitable for the growth of physarum polycephalum. I’ve been facing some issues during this strange ”relationship". The first intriguing thing the physarum did was when it “crawled” out of the petri dishes and connected to each other on my desk.

After witnessing this process I started isolating them and put most of them in a cardboard box. Then the same happened. After that I tried to feed them with leaves that fell off one of my plants after moving to Weimar. First, it was curious to see what it was but immediately stepped back from it. After that I fed it again with oats, but unfortunately they all got contaminated and either formed spores or mold.

[[File:PPMold1.JPG|400px]]

Another experiment was to see how the physarum conducts electricity. There were two problems I have been facing. One was that the voltage it conducted was in a range of millivolts. Second, the agar medium was also a good conductor, so my measurements were not very precise at that stage. Therefore, I transferred the to the cardboard to do experiments, but eventually they all „died“.

===Telecommunication between two physarum===
In this experiment, I want to find a way to let two physarums interact through electronic devices. Two physarums will be in separate containers, the only connection will be through two ESP32s that will capture and transmit the state or other indicators to the other one.

==Project ideas==
Rewarding system for physarum

In my project I will be assessing physarum polycephalum to be used as a sensor. Every organism that contains water and minerals can be used as an electrical conductor and so does it work with physarum. Moreover, the behaviour of the slime mold will be captured through sensors to get a better understanding of it. After doing some experiments and understanding the organism better, the live captured data will be used to trigger something and kind of reward the slime mold to see how it reacts to it.

==Experiment==

The result of an experiment with Physarum Polycephalum and electricity has shown that it is not only a good conductor, but does produce a very small voltage during its growth. The voltage again is oscillating in the pattern of the plasma flow of the organism. The produced voltage and its resulting oscillation needs to be amplified to be able to be used, then send to an Arduino, where the frequency is calculated. Eventually, the signal is send through Serial into Processing, where the frequency is converted to an auditive frequency that can be played on a speaker and a graph that is shown on a screen. At the end, with an exciter speaker, the audio is fed back to the slime mold, to stimulate it. Like a feedback loop, or a self stimulation it interacts with itself and immediately giving the signal back to the computer.

[[File:SPExp1.JPG|700px]]

This work questions the feelings of organisms such as Physarum Polycephalum and how it perceives stimulation or even pleasure. Although it is stimulating itself, it does not know it does so and did not even give consent. It is a very speculative and philosophical perspective on the world of organisms that have no brain or what we describe as consciousness.

The installation is showing a laboratory setting, where a petri dish is prepared with agar medium and electrodes. The cables lead into a box or machine with a screen that is showing the graph, the aesthetics of the box can be compared to an oscilloscope.
When the slime mould is growing it closes the circuit and the millivolts are produced between the electrodes.

==Instructions to build your own==

# Prepare a petri dish with agar medium (2%)
## Weigh 100g of distilled water and add 2 grams of agar
## Cook the medium until it will thicken up
## Divide into Petri dishes or other containers that the surface is evenly covered
# Put two electrodes into the agar as long as it is still liquid
# As soon as the agar solidified divide/cut the agar in the middle, so the electrodes have two independent “agar-blobs” and are not in contact
# Now grow your Physarum Polycephalum
## Take two pieces of the dried specimen and use a pipette to put a few drops of water on it.
## Put each of the piece on one electrode.
## Now wait one or two days and be patient
# Meanwhile, build an amplifier, a good one to use is Martin Howse’s OP-amp (instructions) https://www.uni-weimar.de/kunst-und-gestaltung/wiki/images/Martin-howse.pdf
# Connect electrodes to amplifier and then the amplifier to your Arduino
# Connect your Arduino to your computer and upload the “Arduino Source Code” via the ArduinoIDE on your board.
# Paste the “Processing Source Code” in Processing
# You should now see this message: [[File:ProcessingSerialMessage.png|400px]]
# Then replace the number 0 in the line “String portName = Serial.list()[0];” to the number that is showing up like in this case the 3 before tty.usbserial: “[3] “/dev/tty.usbserial-****””
# In the last step before starting the program remove “//“ before “fullScreen();”
# Now you are ready to listen to your slime mold
