This is an open-source documentation of a low-cost, small-form-factor ultrasonic mist maker. These designs are rarely well-documented online, especially when it comes to understanding their electronics and power needs. This project, created by Shuang Cai and David Yang, aims to make mist-making circuits more accessible for creators, artists, educators, and engineers. By openly sharing tested designs, PCB files, and instructions, we hope to contribute to the open hardware community and enable more people to explore mist as a material.

Ultrasonic mist makers operate using high-frequency vibrations to atomize water into a fine vapor. The device integrates multiple subsystems—piezoelectric transduction, voltage amplification, and digital control—to reliably and efficiently generate mist.
