Particle Flow

by Neonanalog


Granules are driven by gravity and topography forming an analogue particle system. A moving slanted plane and a grid of motorized stamps control the elements to form infinite variations of motion behaviours and patterns. The result is a zen-like experience that is both: fascinating and contemplative.
Created by Cologne based design studio NEOANALOG and comissioned by dreiform and INEOS Styrolution, Particle Flow is an eye-catching physical installation exploring flow behavior of complex granular systems. Mimicing natural phenomena of accumulation and dissolving the piece aims to touch the spectator in an abstract and emotional way.
Software controlled motion follows a complex choreography and enables precise steering of physical particles in a variety of ways: from subtle to obvious, from slow to high paced, from random-like to symmetric.
The motors are driven by a software realized with Processing and Arduino. In the pre-production the team used a MIDI controller to manually trigger and adjust several motion presets and recorded these sessions as JSON files. For the final installation the software randomly picks a pre-recorded session and sends the control commands to the mechanics via ethernet (UDP).
The custom-built mechanics that tilt the plane are driven by three stepper motors, an Arduino UNO and AutoDriver motor drivers from SparkFun based on the ST Micro L6470 chip. A grid of 19 motorized stamps is attached to a flexible textile to form the dynamic topography. Each stamp consists of an analog servo motor and a simple gearwheels mechanic. All servo motors are controlled by one Arduino MEGA 2560. The communication between software and hardware is realized with an Arduino Ethernet, which forwards the signal to the other boards via SoftwareSerial.
