Kinetic little rain is largely inspired by the moving sculpture at Singapore Changi airport created by Art+Com.

This ceiling light is made up of 100 blown glass drops weighing approximately 30 grams set in motion by stepper motors. The motors (JK35HS34-1004 Jkongmotor) are controlled with Tic T500 (Pololu), all ordered with an arduino 2560.

In order to reduce the noise of the stepper motors, I poured silicone molds.the motors are slipped inside these molds, which allows them to be held in place

EXPANDED TECHNICAL DETAILS

Dynamic Suspended Sculpture

"Kinetic Little Rain" is an interactive art installation that replicates the movement of rain using a matrix of suspended physical particles.

  • Multi-Servo Coordination: The project uses a series of Actuonix linear actuators or high-precision servos to pull "Raindrops" (beads) up and down. The Arduino manages the timing of each motor to create wave-like or cascading patterns.
  • Algorithm-Driven Motion: The firmware uses sine-wave math to calculate the height of each drop based on its position in the array, resulting in fluid, organic movement that mimics nature.

Environmental Reaction

  • Sound Mapping: (Advanced version) Integrates a sound sensor; as the room getting louder, the frequency and amplitude of the "Rain" animation increase, making the sculpture reactive to its surroundings.
