Patchouli: Open-Source EMR Drawing Tablet

Patchouli is an open-source electro-magnetic drawing tablet hardware implementation, including a coil array, an RF front end built using commercially available parts, and digital signal processing algorithms. The design is compatible with most commercial pens from different vendors, offering an ultra-low-latency pen input experience for your customized hardware projects.
