MomBoard: E-ink display for a parent with amnesia
Today marks two years since I first set up an e-ink display in my mom’s apartment to help her live on her own with amnesia.
Could stay on for months on end Would let my siblings and I easily post short messages to it that would remain visible until replaced Was large enough and easy enough to read without glasses Required no interaction to wake or read and was relatively foolproof (touching it wouldn’t disrupt it) Was resilient to network failures Didn’t glow at nighttime Didn’t require hardware hackery (I’m a software person) Would boot directly into displaying messages (no interaction needed to start an app) Was not enshittified with a subscription service or proprietary app store Was reasonably affordable Would not look out of place in a home A small web app manifest lets us save the Compose page to a phone’s home screen as an icon for quick access. I couldn’t find a pure CSS way to automatically maximize font size so that a text element with word wrapping would display without clipping.
