Luiz Zanotello’s The New Velocity charts the faulty consistency of cartography — via Creative Applications Network

Created by Luiz Zanotello at the University of the Arts, Bremen, The New Velocity is a machine designed to plot the phantom Sandy Island using digital as a new analogy for its existence.

Sandy Island is a non-existent island that was charted for over a century as being located near the French territory of New Caledonia. The island was included on many maps from as early as the late 19th century, and gained wide media and public attention in November 2012 when an Australian surveyor ship, passed through the area and “undiscovered” it.

The machine records new datasets that support the further existence of the island by manipulating its digital presence.

Sand piles are scanned by an infrared proximity sensor, which moves up and down over a platform replicating the movement of a ship floating over the high seas. The spacial data is mapped and visualized in realtime. Generative output (visuals and mapping) were created using openFrameworks with Raspberry Pi 2 and Raspbian Jessie. Physical motion and sensing were achieved with Arduino Uno + AccelStepper Library including two NEMA 17 Stepper Motors, two DRV8834 Low-Voltage Stepper Motor Driver Carrier, Sharp GP2Y0A41SK0F Analog Distance Sensor 4-30cm, red LEDs and toggle button and handcrafted wood and acrylic cases.
