I LOVE this, but I am still love the Sunday night family bonding moment of planning the week in the pen and paper weekly planner that also costs us $10 a year.

This is great. Always wondered why this didn’t already exist.

My solution is based on 12.48 inch Magic Ink Calendar:

A 12.48 Waveshare eink display costs $175. Sadly haven't gotten it to work with the Raspi Zero and therefore can't use it battery-powered. Got an ugly cord right now. Running power to the right place through the walls is definitely dedication!

You can run rust on kindles, so you don't need a separate webserver. You can fetch stuff and render the image directly on the kindle. Second hand kindles can be very cheap.

However, I would now go for some ~100€ e-ink that is built for hacking.

The cost differential between ePaper displays and the comparatively cheap jumbo tablets will offset higher current consumption for a good long while: https://www.aliexpress.us/item/3256808694032679.html

We do this with a raspberry pi and a decent lcd screen in a picture frame in our kitchen. I like the idea of e-ink but there isn’t a reason to go that route if you want to see everyone’s calendar color-coded while also saving a few bucks.

Love the artistry and dedication in this effort - getting something just right for your own tastes and honing it over time can be really fulfilling.

We use a family paper calendar and I use my watch to check the weather and reminders. Still allows my phone to live in a box at home.

A project, ZerryBit, are working to do something similar - albeit on a far smaller scale physically than what you’ve done here. Might be of interest to OP or others though - further info at https://zerrybit.com/en-us (I have no link to them bar placing an advance order)

I think you're ready to go to market!

The developer recently had a home tour where you can see this software in use
