The original project was just for sleep typing, called Shh Shell: https://davidbieber.com/projects/shh-shell/ https://github.com/dbieber/shh-shell
When I moved out west, I expanded Shh Shell to shower typing too, so I could capture those precious shower thoughts, otherwise fleeting.
A few months ago I rebooted the project as Go Note Go, this time with a focus on driving and camping, rather than showering and sleeping. New hardware (Raspberry Pi 400) in the project lets me use it on the go. https://davidbieber.com/projects/go-note-go/ https://github.com/dbieber/GoNoteGo Lots of improvements over the original project, noted in the post linked here^.
Even though I designed GNG for driving and camping, the old sleeping use-case is still useful for me, and I've continued to delight in keeping the headless keyboard at the bedside. Being able to queue up messages in this state (as well as just from my daily note-taking workspace) has only added to the delight.
