Show HN: Turn a Nintendo Joy-Con into a Codex Micro Alternative
github.com
I built Joy-Con Codex Controller, a bring-your-own-controller alternative to Codex Micro for macOS.
It turns an already paired Nintendo Switch Joy-Con into a one-handed physical controller for Codex. You also need a mic which most Macs already have. The default mappings cover common actions such as switching chats, creating or closing a chat, navigating panels, confirming or cancelling, and holding a button for voice dictation.
The controller has two shortcut layers: pressing a button directly triggers the primary action, while holding ZL or ZR activates an Fn layer. Every mapping is configurable, and profiles can be imported or exported as JSON.
This is an early release, and I’d especially appreciate feedback about the default mappings, different left/right Joy-Con models, and macOS compatibility.
