# Project Patchouli

## Overview

This is the first open-source project I am aware of that has come close to truly understanding what goes into building an EMR tablet. Yukidama is the project lead, and his work has revealed a lot about how these EMR tablets actually work. As of my last check, he had built his own EMR digitizer compatible with an existing Huion pen and OpenTabletDriver on Linux. I believe he is also currently working on building his own EMR pen.
