From the project

An open-source nail art printer.

Unlike commercial alternatives that rely on closed-source hardware and DRM-locked consumables, this project provides a fully open architecture. It uses a distributed processing model, offloading high-level computer vision and web serving to a Raspberry Pi, while delegating strict, microsecond-accurate hardware control to an ESP32 microcontroller utilizing I2S Direct Memory Access (DMA).
