This is amazing! Any thouhgts to commercialize it, or just a hobby project?

  I started to work on this, because this is something I hoped existed. If there is enough interest, I am open to commercializing it. Its super easy to setup, especially given all my code is already open source :)

Great work! I had been thinking about buying an Inkplate but as a hobby project I had wanted to focus my limited time on the application vs all of the glue (UI, Oauth, etc.). This might be the nudge to move me along. Thanks!

Is that font the highest resolution it can be?
- rahulrav 6y ago
  No, that is what looked okay to me. The font sizing on the Calendar is customizable. You can also side load custom fonts. I am going to look into this, because the default fonts are a bit meh.

Hmm I wonder if this will work on the remarkable tablet

  Based on my cursory look at `libremarkable`, the SDK looks a lot more capable. You will need to port the code from Python though :/

Great work on this! I especially appreciate the use of the limited-input device flow, after seeing many device projects that use flows intended for servers :) > Support & configuration for time zones Are you referring to this? [0] Might be out of scope, but from experience, there are some date/time conversions that will require the TZ name (e.g., "Europe/London") to avoid needing to know whether to use the offset value or DST offset value. Could be worth including the canonical names [1] in a future revision. Again, awesome work, and it's pushing me to try an E-Ink project of my own!

  Thanks for your kind words and the tip about using canonical names. Will take a look.
