MomBoard: E-ink display for a parent with amnesia

Really nice project. One idea for “if we fail to take down a message that no longer applies, it confuses her.” Put a start and end date/time on messages and implement in the board. That way you can pre schedule them and have them fall off automatically.

It might be nice to add default messages that can auto-populate the date so she won't notice if network goes down for awhile or someone forgets to post a message.

Nah, at that point, just let mom call.

Agreed, or an expiry timer (e.g. this message expires in 12 hours).

Would also be good to display the current date alongside the messages' date

It looks like it's at the top of the screen

The current date - yes, but messages don't have a date assigned to them

This assumes the mother can form the new memory required to remember to call in that situation, which she by definition of the disease can't.

It (hopefully, theoretically) shouldn't make that assumption. It only relies on her apparent natural tendency to call her kids when/as she believes she hasn't heard from them in some time.
