The keyboard form factor was just missing some kind of unique display and this is perfect to use my old kindle with a broken touchscreen.
What a perfect solution to my niche problem!
Mechanical Keyboard with an OS powering a PaperWhite screen.
Not exactly what I did, but you get the idea. https://liliputing.com/kindleberry-wireless-using-a-raspberr...
This solution seems easier, and more portable.
- iPad Air
- iA Writer iPad App (or: Simplenote)
- TwelveSouth Compass Pro, for use in portrait mode
- Standard Apple Bluetooth Keyboard + Apple Pencil clipped on side
Also, I might be old-fashioned, but when I need to type outside -- which is often -- I just bring my laptop! Lenovo X1C (excellent keyboard) with a great matte screen. Since that's Linux, I usually use vim + goyo, Typora, or Simplenote.
On one of your earlier commits (https://github.com/rberenguel/PiWrite/commit/c23bfdccd43e1c5...), you mentioned using a Pico W. There may be an avenue for that. A few days ago I submitted my Raspberry Pi Pico W Host MQTT Numpad project to Hacker News, but unfortunately it didn't gain any traction. https://gitlab.com/baiyibai/pico-w-usb-host-mqtt-numpad. I detail some of the developments on USB Host mode. There doesn't seem to be native MicroPython support for USB Host mode yet. I did find a project which seems to to load the pico-pio-sdk as a library and use a GamePad for input: https://github.com/danjperron/pico4legsBot
Also, about a year, I wrote down some of the requirements for an e-paper RPI Pico-based e-ink writer in a comment. I wanted to dub mine, 'the microWrite', 'μWrite', 'uWrite', or 'you write' https://news.ycombinator.com/item?id=32092930.
I suppose the question is whether it is feasible to adapt PiWrite to run in MicroPython. The next question is whether one could ditch the webserver-based approach and interface an e-paper screen directly to the RP2040. Waveshare offers MicroPython libraries for their e-paper displays. This might offer better latency.
I've found I enjoy writing on Kindle, despite how limited it was. I make notes by highlighting words in a book and writing them down in a note that was associated with the highlighted word. Clunky but it works.
Using an external server is much better though as it works with my keyboard, allows to keep the writing elsewhere. Very happy with it.
No, but I had really hoped for something beyond glorified paper.
