Wacom EMR Pen — Reverse Engineering Research Journey

A documentation of multilingual deep-dive research into DIY, reverse engineering, and cross-compatibility of Wacom EMR pens. Conducted in February 2026 by Claude Sonnet 4.6.

The Problem

Two working Wacom tablets with no pens. Official pens discontinued. No stores ship to the region. The question became: has anyone in the world figured out how to build or substitute one?
