we’re a part of the st. cecilia sound art project that runs this friday, january 28, from 8-10, and this saturday, january 29, from 2-9, at 21 monitor st., brooklyn, ny (greenpoint). directions and map below.
the show is organized by Rabid Hands and features many artists in a variety of media who have filled the former convent with projects.
we have two new pieces in room 307, minimal audible fields, and feedback f s f -r s ns:
minimal audible fields generates visual compositions in response to low frequencies at the threshold of sound and vibration propagating through the convent during the exhibit.
materials: LEDs, micro-controllers, sensors, mixed media.
minimal audible fields is a robotic work whose inputs are low frequency sound and vibration on-site. every 54 seconds the project analyzes the past 54 seconds of sound and vibration, and compares its readings with the previous set of data it generated 54 seconds in the past. the pattern of LEDs is determined by this comparison. the timing of the piece is intended to permit visitors time to look at the compositions generated by the project.
feedback f s f -r s ns is composed of two robots, and is in the form of a closed system with interlaced feedback, i.e, the output of one robot is the input of the other. the system generates visual compositions as the robots alter their environments and influence each others’ behaviors.
materials: various reflective and refractive media, micro-controllers, motors, lasers, sensors. 2011
output: slowly rotates a glass tumbler containing reflective/refractive media.
output: light, fluctuations in the emf field (via motor induction, phosphorescing of chemicals on the sensor of robot 1).
robot 1 is programmed to sense changes in the emf field around it and reposition a container of reflective/refractive media proportionally by spinning a motor.
robot 2 is composed of three servo/laser components programed to survey the surface of robot 1’s glass tumbler and define quadrants of highly reflective points on the tumbler’s surface.
robot 2 is programmed to draw straight lines with a laser on the curved, translucent, rotating surface of robot 1. the light from the lasers pass through a rotating tumbler (robot 1) filled with a mixture of reflective, and refractive media.
as the beams of light pass through the tumbler, their trajectories are refracted and the resulting altered beams strike a treated sensor plate and phosphoresce.
the phosphorescing and servo motor movement ripple the emf field and robot 1 spins the tumbler accordingly. the moving tumbler causes robot 2 to re-scan the surface of the tumbler, etc.
we’ll be there friday/saturday, so if you’re headed out let us know! if you’re out on saturday afternoon and hungry, we’ve been eating at a great little vegan place called boneshakers that is just two blocks from the convent.
