Tags: clojure, e-paper, notebook, repl, remarkable

Score: 6.3/10 (Innovation: 8, Technical: 7, Documentation: 6, Utility: 4)

Clerkenwell is a Clojure notebook environment that creates a two-way binding between a reMarkable 2 e-paper tablet and an Emacs CIDER REPL, allowing handwritten notes and REPL output to be mixed in real time. It's a novel combination of hardware hacking, Clojure tooling, and computational notebooks, though currently limited to a single device and firmware version.

Target audience: Clojure developers, emacs users, researchers, and digital note-taking enthusiasts
