Reads heartbeat sensor to create perfect water droplets in total silence.

Client needed a device to reliably produce droplets of water for a piece of performance art. Because the piece was to be performed in a gallery setting, little to no acoustic noise was permissible during operation, ruling out conventional DC motor pumps and solenoids. Solution was a stepper motor fitted to a peristaltic pump using motor drivers designed for making 3D printers operate quietly. Fabricated PCB to package electronics, wrote firmware to read heartbeat sensor and drive motors, and did mechanical design and manufacturing to produce the monolithic finished actuators. This project is one of a series of jobs I've completed for interdisciplinary sculpture artist, Sara Dittrich.
