This is a test of the mechanism for driving the physicalized output of the software solar wind harp for the "Aurora's Aeolian Harp" project.
I am using an Arduino board with a Motor Shield, and Arduino software co-written with Chris Coleman to control motor speed and direction based on the Max patch that derives control data from real-time ACE satellite solar wind data. The Harp software interfaces with the Arduino board via another Max patch that conditions the data for the serial port.
The motor drives tuning pegs that adjust tension on physical strings. The strings cause sheet metal plates with attached audio transducers to bow and flex, which causes fluctuations in the tones that are output from the Harp software to those attached transducers.
This is a "proof-of-concept" demo video. More to follow.
