My first Bare-Bones Arduino

Completed board

I just assembled my newly-arrived Bare-Bones Arduino clone, developed by Paul Badger. How great! Not only is it perfect for embedding in projects, but the instructions Paul made to go along with it make it so easy. I wish I had a teacher like him when I was learning the basics of physical computing! I used double-male header pins (graciously given by Mr. Badger) for the digital i/o so that I can plug the BBB into a solderless breadboard or plug stuff in on top. I have three more kits to assemble. This board is much easier to deal with than the NG (that communications chip is really hard to solder), and the Atmegas come pre-bootloaded. The development of this board is a case in point for why open source hardware rocks. Thanks, Paul!

Declarative Lamps Unveiled

After some last minute troubleshooting, Rees and I installed the Declarative Lamps in Kingston, NY’s Peace Park on Friday morning. The official Kingston Sculpture Biennial opening was Saturday, July 7, and will be up through October. Check out the project page for the full story and overview video!

Declarative Lamp Project

Sternlab’s Becky Stern has collaborated with artist Rees Shad on the Declarative Lamp Project, on display as part of the Kingston, NY Sculpture Biennial through October, 2007. (Lamps are on display in the uptown Kingston Peace Park)

Mr Shad writes:

In January of 2007 the city of Boston was partially paralyzed by a bomb scare wherein a number of found electronic devices were seen as potential explosives. The devices featured a number of small flashing lights depicting a cartoon alien performing a crude gesture. Intended to advertise the upcoming season of a popular animated television show, this misadventure in guerilla marketing was perceived as a potential hazard to the population, or, even worse, a terrorist act. The Bomb Squad was called out to destroy the devices, and the city’s major traffic paths came to a standstill for most of an afternoon. My first thought upon hearing about the Boston scare was that our fears had gotten the best of us. My next thought was that I needed to address this in my work as an electronic installation artist.

The Declarative Lamp Project, created in collaboration with artist Rebecca Stern, uses electronic performance to explore the extent to which fear has been instilled in American culture. Witnesses in a park experience seemingly innocuous electronic pathway lighting that comes alive at dusk with lights and voices in many languages declaring, “I am not a bomb.”

Because these devices exist in a natural environment and use human voices, I wished to add natural and personal elements to the Lamps’ execution. As a child I remember being fascinated by the mathematical equation to calculate air temperature from the frequency of cricket chirps. If one monitors a single chirping cricket for 15 seconds, the number of chirps plus 39 is the air temperature (in Fahrenheit). In our piece, this equation has been reversed to allow the evening’s temperature to establish the rhythm of the declarative voices. In cold temperatures, the lamps speak less often than in warm.

To give an innocuous overtone, we chose a number of Arts & Crafts style solar powered garden lights as the framework within which to build our project. Ordinarily these lamps store energy during daylight hours and engage an energy efficient LED light at dusk. Ms. Stern and I have repurposed these lamps to flicker as if they hold lightening bugs in correlation with the recorded messages. This process begins at dusk, producing a chorus of voices whose rhythm is directly related to the temperature of the evening air. The lamps each repeat the phrase “I am not a bomb” in one of twelve languages. After a twenty-minute performance, the lamps power down to await the next sunset.

Tyvek Lunch Bag

I made a reusable lunch bag out of a FedEx Tyvek mailing envelope. I modeled it after a paper lunch sack. To keep glue away from our food, I used a sewing machine to do up the seams. Because Tyvek is tear-resistant, the stitches should hold it for many lunches. It should make a great water resistant, reusable alternative to the paper sack. I don’t expect it to last forever, just until I find another free Tyvek envelope.

Charlie’s Birthday Surprise

My boss, Charlie, took the day off on Monday for his birthday. Since the computer lab is desolate in the summer, we have a little time and a lot of equipment on our hands. Dave, the head of the lab, made a Max/MSP patch that flashes bright colors and the text “Happy Birthday Charlie” in a random font and location. We piled as many monitors into Charlie’s office as we could and hooked up computers to drive them. When Charlie came in to work on Tuesday, he had a big surprise waiting!

He loved it!

LED Bike Helmet

I was always losing those lights you clip on to your bike, and they’re not cheap or good quality. I had wanted to play with conductive paint for some time, so I purchased some in order to attach safety LEDs right to my bike helmet. I have made a page on Instructables detailing its construction. Here’s a nice picture, however, which is a link to the Flickr set. You can also view the circuit schematic.

Fake MySpace

I made myself a MySpace page that lives off the MySpace servers. It’s half fake and half links to other places.

Holon A.

Holon A.

Materials/Languages: Various

The word “holon” signifies a collection of nested systems. Based on the writings of Michael Pollan and Arthur Koestler, Holon A. reflects the holons of American industrial agriculture through an interactive miniaturization. Five integrated modules invite the visitor to ask questions about the efficiency of our industrialized ecosystems. Diorama-style modules cover such topics as E. coli contamination during fabrication of beef, the varying public uses of the term “chicken,” traditional fiber arts, and the government’s role in the American corn economy. Holon A. utilizes a wide variety of industrial and hand-made materials from electronic components and wood to hand-silkscreened plush steak.

The modules

The radiation level required to combat E. coli contamination of livestock varies with the amount of corn in the cattle’s diet, as it is not its natural food source.

Corn Currency asks about the US government’s role in the market value of corn, and when the corn economy is good, livestock eat more of it. The visitor is left with plastic waste.

The cornstalks’ adjustable light source self regulates the light output and also influences glowing of the beef module.

Cornstalks

The fiber module consists of a knitted viewer with sound to encircle the face, giving the feeling of a private space. The conforming body of the knitted object reflects our once traditional fiber practices being industrialized under our noses.


Live Internet-scraped images can be seen as the somewhat “public” opinion of chicken today. The visitor has control over the playback of these images.

The modular, rough-cut construction fits with the conceptual framework of industrialization of nature.
