Arduino research 17/05/2018

Today I’ve been looking at how to build the various Arduino circuits for the Space Rocks, and at some examples of relevant projects.

I made some basic sensor experiments with a Light-dependent resistor, ultimately using this code from the Make: Getting Started with Arduino book.

// Example 06b: Blink LED at a rate specified by the
// value of the analogue input

# define LED 9 // the pin for the LED

int val = 0; // variable used to store the value
 // coming from the sensor

void setup() {
 // put your setup code here, to run once:

pinMode(LED, OUTPUT); // LED is as an output

// note Analogue pins are
 // automatically set as inputs
 }

void loop() {
 // put your main code here, to run repeatedly:

val = analogRead(0); // read the value from the sensor

analogWrite(LED, val/4); // turn the LED on at
 // the brightness set
 // by the sensor

delay(10); // stop the program for some time

}

And this circuit:

Also stumbled upon How to Build an Arduino synthesizer with Mozzi library

The Mozzi library looks super-useful for sound generation:

Currently your Arduino can only beep like a microwave oven. Mozzi brings your Arduino to life by allowing it to produce much more complex and interesting growls, sweeps and chorusing atmospherics. These sounds can be quickly and easily constructed from familiar synthesis units like oscillators, delays, filters and envelopes.

You can use Mozzi to generate algorithmic music for an installation or performance, or make interactive sonifications of sensors, on a small, modular and super cheap Arduino, without the need for additional shields, message passing or external synths.

Note to self to also check out the Mozzi examples gallery.

This week’s research – 06/04/2018

Thinking this week about echo location, in the context of the space objects ‘talking’ to each other and sensing the distances between themselves.
https://en.wikipedia.org/wiki/Animal_echolocation

Found some inspiring projects in A Touch of Code.  Most notably (so far):

  • Markus Kison’s Touched Echo, using sound conducted through bones. Visitors put themselves into the place of the people who shut their ears away from the noise of the explosions. While leaning on the balustrade the sound of airplanes and explosions is transmitted from the swinging balustrade through their arm directly into into the inner ear (bone conduction).
  • WhiteVoid’s ‘unstuck’ augmented game.
  • “Experiencing Abstract Information” by Jochen Winker and Stefan Kraiss
  • And Leonel Moura’s Robotarium. The first zoo in the world for artificial life.
  • Drawing Machine  by Fernando Orellana. Explores the notion of generative art or art that makes art on its own. The piece consists of a three tiered mobile sculpture that is driven by the vibration of a motor.

  • LITERALLY SPEAKING Torsten Posselt, Martin Kim Luge – transforms tweets from twitter-users into the sound of singing birds.
  • Kathrin Strumreich’s fabric machine. Two fabric loops, driven by a motor, create a division in space. Light sensors measure the opacity of the textile.

Love the design and the sounds of these Bivalvia mini synths.

And some musical inspiration for the Space Rock objects from Hatis Noit; especially the way the first track here plays with voice – using various layers, some treated and distorted, some not.

Research and inspiration 27/03/2018

Discovered the artist Amulets this week. He works with cassettes, players, tape loops and effects , creating woozy soundscapes and atmospheres from these simple sources. Of particular interest is the physical aspect of what he does, manipulating the sounds and machines in real time.

Also reading The Oxford Handbook of Interactive Audio, with a view to developing a more theoretical approach to the sound that will be part of my final installation.

Currently experimenting with combining simple tones to make chords / walls of sound, using this for reference: Frequencies for equal-tempered scale, A4 = 440 Hz

Panned version.

Mono version.

Also read this piece recently on FACT – The Sound of Fear, which mentioned the Ghost Tape Number 10, which was unpacked in this podcast a while ago. An interesting example of using sound to play on people’s cultural preconceptions.

During the Vietnam conflict, US troops played a soundtrack known as Ghost Tape Number 10 against the soldiers of the National Liberation Front. Used as part of Operation Wandering Soul, the unsettling tape collage tapped into Vietnamese beliefs that ancestors not buried in their homeland roam without rest in the afterlife. This spooky mix of voice, sound and music was intended to haunt Vietnamese soldiers and encourage them to abandon their cause.

Quite intrigued by this visualisation of sound in space via AR. Discovered this while reading about the Weird Type AR app.

I have also been investigating a few options for networking and interacting with the objects that will be the 3D models in the installation.

One is X BEE – apparently “the Digi XBee3 Series offers design freedom with easy-to-add functionality and flexible wireless connectivity.”

Another is the Google’s Project SOLI, a sensor which recognises hand gestures.

And finally, a MIDI controller ring, The Wave, as featured on TechCrunch.

Sadly the last two will not be available for a few months yet.

Processed stories: 2. Made Little Idea

Second text created using Markov chain text generation. Again, the text is in the order it was generated, although some slight edits have been made to give the text a bit more flow and ‘sense’.

Made little idea where he was
connect the bothersome sounds of the Earth
only family
had aged in the Desert,
a location on,
announcing the lens,
much less of the horse,
scans the space of whom,
announcing around the music,
waiting like electricity,
and intense, despite simple,

was being much like those back home.

 

Reported quite signals.
As he turned the cottage
whomever was great,

but maybe we’re not quiet.

 

To be honest, they too had seen the nature
wandered
not only more lush
and was unable to make the journey
back to the camera

shows not only family.

 

Looking back
their artists tried
the object details

tenderly.

 

These people live
significant mountains,
much like spider life,
that’s existence

quite done with wandering after all.

 

Being from and surprises the edges.

 

Even as a small life here,
as he looks closely,
careful to ignore
the leaf presents itself,
at first, as he thinks, as she named Kathy,

in honour of the sounds of the object.

 

Families gathered
spirit beautiful,
announcing she is assigned the airport,

sparsely, tendency, finally around the screen.

 

These people live a small listen
to take the creative commune
complex understanding

much less of the object.

 

Under closely, which finally that.

 

A web of careful
to connect is assigned

the artist’s ranch.

 

When they all listen.

 

A kindred spoil the communicating
back down is taken in a row behind

the council would change us all.

 

Or at the flickering moon shots,
the camera shows Beachtown USA,
situated near others

the moon landings.

 

Taken.

 

A kindred spirit beautiful,
and screen searching
signed the dial
view of decided
that is the pictures from memory

and the small life deciphering the stars.

 

As the lens near the Golden Gate Bridge

come riding horses.

 

Some before.

 

A celebration and spirit
behind the sound of the base

the contact with wandering travel.

 

The lens near other
means camera when the moon.

They travel.

 

Hopeful to think
she thinks,

object is so near as macro.

 

The live a similar kind,
was a pretty good idea while they knew it
was concert

would do the pictures from the lens.

 

Looking at this
was taken in by the concert

have begun.

 

Sat on his

As he once again see scans them.

 

However, he had it.
They create as them.
However, he looks closely, careful to ignore they made.
With safety being near othered

occasionally the Earth.

 

The lens,
as only that there to find the lens.
Looking at thinks,

she notices that finally.

 

A web of carefully during its travels across space

mission for survival.

 

Even as we can tell,
static, waiting to pass.

Before static, waiting the home rest.

 

The city that’s existening
back down,
announcing the moon landing wasn’t enough,
because life wandered
was his headquarters, tunes,
looking for signal would come

time has passed.

 

More stop outside of the creative commune
inhabitants, the lab; an hour.
She glances up momentarily at the violins,

much; it was, but they weren’t enough the map.

 

An experience
up momentarily at a secret astronaut
analysed and scattered

Looking at some sound so much;
it was unable to make the create

a sort of us.

 

Hopefully measured veins branch through others
and he decided the collects
antique photos of they weren’t enough,

because life.

 

Maybe was unable to take in the moon.
The sounds they knew the parlour.

They played from memory and the edges.

 

An easier time.
Before will be a fanfare.
A kind, was off to ride
collects antique photograph shows
not so much like electricity,

and the bother means came naturally, tenderly.

 

The sound of the same from the subject.
Unfortunately, tendency to be honest, they trail.
Where he wasn’t enough
other life, general
leave this cue to ride towards home,

and sounding like spider legs.

 

An expedition is.
Out in the Sun
a little idea
where to follow the map and in had it.
The grainy black and white screen.
Another life.
She had food and was being much like the journey
back to the photos of the city

the rider closely.

 

Families gather place.
Gazing in
stopped, tuned, rode again.
It was near to reach it,

communicating against the stars.

 

Lens near other side of time
to connect the screen.
They knew it took some sound.
Occasionally too
had seen this horse,
she tunes,
once again see

scanning their artists travel.

 

Being and expedition is sentimentarily
at a newly acquired piece mounted.
They all smile into her colleagues.
She adjusts the home
side of the commune
and takes it to his her –
she notices sound made little,

he came named.

 

Many have since suggested the decided that reminds they made.
 Without the craft the newly-acquired family

 

Research and inspiration 17/03/2018

Some links and thoughts from the past week.

This episode discusses the emoji-based augmented version of Bosch’s Garden of Earthly Delights by Carla Gannis, along with the concept of companies and institutions owning the ‘airspace’ or virtual space around  their properties, such as paintings. It also discusses whether we will be able to buy virtual land, as you can already do in Second Life. Particularly poignant in light of this piece I read recently on fastcodesign.com, about ‘digital artists’ hijacking MOMA with AR.

This also sparked some research into RGB-D.
“In the past years, novel camera systems like the Microsoft Kinect or the Asus Xtion sensor that provide both color and dense depth images became readily available. There are great expectations that such systems will lead to a boost of new 3D perception-based applications in the fields of robotics and visual & augmented reality.”

Intriguing short video that makes you wonder if it is CGI or a model / set:
Club Palace (Real or CGI?) – NOWNESS. Inspiration for the ‘set’ around the What Goes Around space objects, perhaps?

Have also been exploring how to network the various sensors that will be attached to the Space Rocks wirelessly, and investigating XBee:
https://www.arduino.cc/en/Main/ArduinoXbeeShield

Also been investigating the Arecibo message…a short radio message sent into space to celebrate the remodeling of the Arecibo radio telescope in Puerto Rico in 1974.[1] It was aimed at the globular star cluster M13, about 25,000 light years from Earth. M13 was chosen because it was the right size, and was in the sky at the right time and place for the ceremony.


And the response that someone created:

 

 

 

 

And also The Von Neumann Probe (A Nano Ship to the Stars). 
Simply put, a Von Neumann probe is a self-replicating device that could, one day, be used to explore every facet of the Milky Way in a relatively small window of time.
