Machine Data Dreams @ Black & White Projects

This week, I opened a solo show called Machine Data Dreams, at Black & White Projects. This was the culmination of several months of work where I created three new series of works reflecting themes of data-mapping, machines and mortality.

The opening reception is Saturday, November 5th from 7-9pm. Full info on the event is here.

Two of the artworks are from my artist-in-residency with SETI and the third is a San Francisco Arts Commission Grant.

All of the artwork uses custom algorithms to translate datasets into physical form, which is an ongoing exploration that I’ve been focusing on in the last few years.

Each set of artwork deserves more detail but I’ll stick with a short summary of each.

Fresh from the waterjet, Strewn Fields visualizes meteorite impact data at four different locations on Earth.

As an artist-in-residence with SETI, I worked with planetary scientist, Peter Jenniskens to produce these four sculptural etchings into stone.

When an asteroid enters the earths atmosphere, it does so at high velocity — approximately 30,000 km/hour. Before impact, it breaks into thousands of small fragments — meteorites which spread over areas as large as 30km. Usually the spatial debris fall into the ocean or hits at remote locations where scientists can’t collect the fragments.

And, only recently have scientists been able to use GPS technology to geolocate hundreds of meteorites, which they also weigh as they gather them. The spread patterns of data are called “Strewn Fields”.

Dr. Jenniskens is not only one of the world’s experts on meteorites but led the famous  2008 TC3 fragment recovery in Sudan of the Almahata Sitta impact.

With four datasets that he both provided and helped me decipher, I used the high-pressure waterjet machine at Autodesk’s Pier 9 Creative Workshops, where I work as an affiliate artist and also on their shop staff, to create four different sculptures.

The violence of the waterjet machine gouges the surface of each stone, mirroring the raw kinetic energy of a planetoid colliding with the surface of the Earth. My static etchings capture the act of impact, and survive as an antithetical gesture to the event itself. The actual remnants and debris — the meteorites themselves — have been collected, sold and scattered and what remains is just a dataset, which I have translated into a physical form.

A related work, Machine Data Dreams are data-etchings memorials to the camcorder, a consumer device which birthed video art by making video production accessible to artists.

This project was supported by an San Francisco Individual Arts Commission grant. I did the data-collection itself during an intense week-long residency at Signal Culture, which has many iconic and working camcorders from 1969 to the present.

During the residency, I built a custom Arduino data-logger which captured the raw electronic video signals, bypassing any computer or digital-signal processing software.data_loggerWith custom software that I wrote, I transformed these into signals that I could then etch onto 2D surfaces.Screen Shot 2015-08-02 at 10.56.15 PM I paired each etching with its source video in the show itself.

Celebrity Asteroid Journeys is the last of the three artworks and is also a project of from the SETI Artist in Residency program, though is definitively more light-hearted than the Strewn Fields.

Celebrity Asteroid Journeys charts imaginary travels from one asteroid to another. There are about 700,000 known asteroids, with charted orbits. A small number of these have been named after celebrities.

Working with asteroid orbital data from JPL and estimated spaceship velocities, I charted 5 journeys between different sets of asteroids.

My software code ran calculations over 2 centuries (2100 – 2300) to figure out the the best path between four celebrities. I then transposed the 3D data into 2D space to make silkscreens with the dates of each stop.

This was my first silkscreened artwork, which was a messy antidote to the precise cutting of the machine tools at Autodesk.

All of these artworks depict the ephemeral nature of the physical body in one form or another. Machine Data Dreams is a clear memorial itself, a physical artifact of the cameras that once were cutting-edge technology.

With Celebrity Asteroid Journeys, the timescale is unreachable. None of us will ever visit these asteroids. And the named asteroids are memorials themselves to celebrities (stars) that are now dead or soon, in the relative sense of the word, will be no longer with us.

Finally, Strewn Fields captures a the potential for an apocalyptic event from above. Although these asteroids are merely minor impacts, it is nevertheless the reality that an extinction-level event could wipe out human species with a large rock from space. This ominous threat of death reminds us that our own species is just a blip in Earth’s history of life.

 

Getting into 123D Circuits

I’m a convert to 123D Circuits and not just because I’m an Autodesk shill (full disclosure: I’m in the residency program), but because it has the shared component library that anyone can tap into.

What I’m designing is a PCB that goes to your Raspberry Pi cobbler breakout with some basic components: switches, LEDs, and potentiometers. I’m getting some great help from one of the 123D Circuits team members. It’s going to build on some of my Raspberry Pi Instructables, as well as be a critical component in my upcoming Bot Collective project.

Here’s the preliminary circuit diagram…see anything wrong?

Fritzing, the other viable competitor — as much as an open source program can be considered so — has a snappier grid system and is faster. It is after all, a desktop application and doesn’t have the odd performance issues in a browser app.

However, 123D Circuits has a community. Bah, a community, why is this important?  (see below)

Screen Shot 2014-04-10 at 10.00.23 PMWhat won me over to the 123D Circuits…besides the fact that I know the some of the people who work on the product: the MCP3008 chip. I need this chip for the Raspberry Pi ADC do-all circuit that I’m building.

123D Circuits has it. Fritzing doesn’t. That’s because someone out there made the chip and now I’m using it. 123D FTW.

Accidental Raspberry Pi Selfie

While monkeying around with the Raspberry Pi and the camera and the GPIO, I took this selfie. I guess the camera was upside down!

The Raspberry Pi is pretty great overall. The real bugaboo is the wifi and networking capabilities. You still have to specify these settings manually.

But the cost, only $40! I have 4 of them running now, all doing different tasks. Perfect for my upcoming Bot Collective project (lots and lots of Twitterbots)

7/10 stars.

Ultimate Raspberry Pi Configuration Guide

I’m still recovering from my broken collarbone (surgery was on Wednesday). Today I’m definitely feeling ouchy and tender. I get pretty wiped out walking around outside with the jostling movement, so have been staying home a lot.

To keep myself busy, I’ve been working on a backlog of Instructables for my residency at Autodesk.

This one is called the Ultimate Raspberry Pi Configuration Guide — it took a long time to write!

Even with two-hands and full mobility, it would have been arduous.

Welcome to the Party: @lenenbot

Say hello to the latest Twitterbot from the Bot Collective: @lenenbot

vlad_john_lenen

Lenenbot* mixes up John Lennon and Vladimir Lenin quotes. The first half of one with the second half of the other.

Some of my favorites so far are:

Communism is everybody’s business.
It’s weird not to be able to run the country.
Revolution is love.

There are more, surreal ones. There are about 600 different possibilities, all randomized. Subscribe to the Twitter account here.

 

 

* I chose the name “Lenen” to avoid confusion. Lenonbot and Lenninbot look like misspellings of Lennon and Lenin, respectively. Lenen is it’s own bot.

@maewestbot goes online

I recently activated the latest Twitterbot (5th in the quotebot series), running off the Raspberry Pi in my closet. Say hello to @maewestbot.

She’s only got 4 followers, so far and 1 of them is me, but every rising star has to start somewhere,

Her zingers such as “Is that a gun in your pocket, or are you just happy to see me?” have mutated in various forms (banana, cellphone, harmonica, dropper post, etc).

Here’s a great mini-compilation of Mae West quotes
