Circuit

Through the telephone headset you can hear the AM long-wave radio, recognizable as radio with help of the diode.

AM receiver consists of:

  • Two coils (copper wire 22): 1st band of 40 turns and 2nd band 30 turns
  • 1N34A Germanium diode
  • 47k Capacitor
  • Variable Capacitor
  • Telephone headset – headphones
  • Insulated wire: 50ft for antenna / 25ft for grounding cable

Pulling radio waves, tapping in, circuiting, a translation,   somehow nothing feels so present as working with radio waves. But it is rather an act of presence.  Distance is compressed.  There is a leap in time. Wrapping the coil around the object keeps one present. If you are counting the turns, as any good crystal radio aficionado is supposed to, you cannot lose yourself in the action fully. I sometimes did this canal-side. It feels like a mantra.

During my time at Dinacon I was making radiophonic objects to create kinds of living documentary installations working with radio waves, found and archive objects and sound – the
so-called inanimate, the man-made and the natural.  They are something like witness objects.

I brought the pill bottle at the center of this pod from my grandmother’s house. Both my grandmother´s parents lived for a time in Panama, individually emigrating from the West Indies to Panama before coming to the States and eventually meeting each other in a church in Bedford–Stuyvesant, over 100 years ago. This pill bottle is for thyroid medication. My Grandmother´s thyroid was damaged as a child, burned through iodide painting, an experimental practice of the time. This left her with a permanent thyroid condition that she has been taking medicine for ever since.

I spend time in Gamboa´s Soberanía rainforest, sometimes recording alone and others times with Dina colleagues who made exploring a much more curious experience…

On the Laguna trail, Lisa Schonberg demonstrating the many sonic layers heard and unheard in this jungle – recorded with an ultrasonic mic.

Mostly the village of Gamboa seems like a ghost town, abandoned structures and houses.  You could easily walk the loop of the town without crossing another pedestrian.

But it does not sound like you are alone! Two sonar worlds seemed to rule here, the balance unknown:  

1) That of the jungle, which the town is carved and shaved into. These are sounds from inside the trees, the dirt, and grass, and the sky above.  As I rendered these sounds into words I think of my childhood books, a collection of descriptions: roaring, picking, tweeting, buzzing…, amongst my first words practiced just after Moma and Dada and no, no, Rabía no!   

2) The other sonar world sounds from the bordering canal. “Canal” is quite appropriate: a vibrating, tremble, something like a “horn blows low”.   It is a recognizable machine-at-work sound. And water

Does the nature remember, what? 

The people remember the territory occupied.  They remember who lived on which side of town.  Pastor Wilbur explains: “The Black West Indians lived on this side…” 

This town exists as an important drenching point.  Here in the town of Gamboa the land is always sliding into the canal and must constantly be dredged.

I  often wander around Gamboa town and I sometimes go to  Panama city for supplies. I record folks I meet, not on the street but along the way: a young man who is the son of Panamanian canal engineer- one of the only in his position during those times when Americans ran everything to do with the Canal; an American pastor recruited to preach in English over 40 years ago; and the local sign builder.  And I collect sound archives.  



The Americans came up with the locks as a solution for the canal project the French gave up on. 

Matthew Parker:
“[The canal] did not so much impact on the environment as change it forever. Mountains were moved, the land bridge between the north and south American continents was severed, and more than 150 sq miles of jungle was submerged under a new man-made lake. To defeat deadly mosquitoes, hundreds of square miles of what we would now call “vital wetlands” were drained and filled, and vast areas poisoned or smothered in thousands of gallons of crude oil.”
– Changing Course, The Guardian

 Many lives have been lost in the building of the canal, most to accidents and others to yellow fever.   The majority of lives lost were black men from the West Indies. Thousands died drenching the canal – over 20,000. 

I recover items from the River Charge:  flip-flops, obviously modern, so many types and sizes of flip-flops -there is something about shoes that are haunting – and find lots of pesticide containers and bottles of many different sorts. 

The Americans made there own little universe in Panama. The archives are astounding – and some shameless. ...”it was a provincially ordained world empire domination that the U.S. was meant to enjoy” – Jackson Lear

complexity + leafcutters: code/improvisation

The shimmering, industrious leafcutter ants that build highways on the forest floor make up a complex adaptive system – the sophisticated structures and patterns that they build are well beyond the sum of their individual parts. The ants’ collective intelligence emerges through the repetition of simple tasks, and somehow through self-organization they build cities without architects, roads without engineers. There’s something magnetic about their energetic movement as they carve through the jungle – wherever I found them at Gamboa, I found that I could not look away.

I altered the code from a classic NetLogo simulation to model the behavior of the leafcutters. NetLogo allows you to code agent-based models and watch them play out over time – each of the ants acts as an autonomous “agent” with a simple task to perform, and the iteration of multiple ants performing these tasks begins to simulate how the ants behave in the jungle. What starts out as random walking drifts into road-like patterns as the ants pick up pixel leaves and deliver them to their digital fungus…

Ant Tasks:
1. choose a random angle between -45 and 45 degrees
2. walk 1 unit in that direction
3. repeat.
4. IF there’s food (green leaves or pink flowers), pick it up by turning green, and deliver it back to the fungus at the center.
5. IF you sense digital pheromone (ants carrying food tag the pixels they walk over with digital “scent” as they head to the center), follow that pheromone.

The Twist: music
A symphony of digital fungus stockpiling
An audio representation of the complex patterns and surprising order that arises from randomness…

Each ant in the simulation has an ID number, and that ID number corresponds to a note on the piano. When an ant picks up a leaf and successfully brings it back to the fungus in the middle, that ant will sound its unique note. I calibrated this so that extremely low notes and extremely high notes on the scale won’t play – instead of those extremes some ants are assigned the same middle C, which you can hear throughout the simulation over and over like a drum beat…

the simulation: turn up the sound!

The ants play their own bebop, they compose their own Xenakis-like songs. No two ant improvisations will be exactly alike; whenever you run the simulation, each ant makes different random choices and the behavior of the model will be different. But they sound like they spring from the same mind:

ant improv #1
ant improv #2
the ants start searching for food
making highways
one food source left…
starting the last highway

Our minds love patterns too – I find myself cheering the ants on when I watch the simulation, rooting for them to find the next leaf, hoping for them to route into the highway pattern, waiting to hear their eerie plunking, playful jazz…

extensions for this project:

-there is a web extension for NetLogo, but without sound; could translate these ants into Javascript/p5.js so users can press “play” themselves online and control different variables (how many ants? speed of ants?)

-connect the MIDI sound that the ants are making to a score, print out sheet music written by the ants, play it on the piano

-make the model more complex, closer to the structure of actual leafcutter colonies: different sizes of ants, different tasks…

-interactive projection version

you got this, ant.

Thanks to everyone at Dinacon!

The Frog Show – by Mónica Rikić and Ruben Oya

Frog Show wants to elevate the singing frogs to an audiovisual experience.
Since our arrival to Gamboa every evening we were amazed by their singing. It didn’t sound like the frogs we knew. This was more of an electronic synth-like music performance. We saw opportuniy to join the frogs and develop some visuals to add to the show.

With the goal of low impact on the environment and not disturb the frog’s activity we came up with this solar-powered red LED installation. The solar power makes the system self-sufficient and the red light is known to be less perceived by frogs.

The installation relies on the following hardware: microphone, arduino board, battery pack, solar panel and LED strip.

Testing

The light effects are audio reactive and controlled through code on the arduino board. Every single frog sound triggers the LED strip depending on it’s volume.

The result is an installation that charges during daytime and activates at night with the frogs’s concert. You can read the intense activity of the animals through the light show.

Technical details:

  • Arduino Nano
  • Adafruit MAX4466 microphone
  • 12.000mAh 2.4A 5V battery pack
  • 7W solar panel
  • 1,5m WS2812b LED strip
  • arduino code based on neopixel library.
