MomBoard: E-ink display for a parent with amnesia
An engineer’s simple e‑ink “message board” for his mother with anterograde amnesia has drawn wide interest as a humane use of technology to preserve connection and reduce anxiety. Commenters explore how such always‑on, low-distraction displays could help people with cognitive or sensory impairments, share practical hardware and software options (from Raspberry Pi and Inkplate to commercial products like TRMNL and KOMP), and reflect on design details like expiring messages and clear timestamps. The thread also prompts broader reflections on memory, dementia vs. amnesia, and how consumer tech often overlooks the needs of older or impaired users.
Emotional response & medical context
- Many readers found the project deeply moving, highlighting how simple tech can preserve dignity, reduce anxiety, and communicate love.
- Several compare the mother’s condition to classic anterograde amnesia cases, noting the paradox of being unable to form new explicit memories yet still learning routines or emotional associations.
- Some share personal stories of relatives with amnesia or dementia, emphasizing the daily distress of “not remembering that you don’t remember.”
Similar DIY projects & ideas
- Multiple people describe their own e‑ink or tablet setups: Raspberry Pi dashboards, Telegram/image‑gen boards, photo frames, and family calendars.
- One recurring idea: a simple, wall‑mounted e‑ink device that periodically renders a markdown or HTML page from a URL.
- Others repurpose old Kindles, Kobos, or Nooks as passive web dashboards, sometimes jailbroken and scripted via Python.
Commercial and hackable e‑ink products
- Numerous products are mentioned: TRMNL, Inkplate boards, Invisible Computers’ e‑paper calendar, framed news displays, KOMP, Luna, Boox tablets.
- TRMNL draws both enthusiasm (hackable, OSS firmware, private plugins) and concern (cloud dependency, paid “Developer Edition,” documentation gaps), with clarifications that self‑hosting is possible by reflashing firmware.
- Some note subscription costs (e.g., KOMP) as steep.
Design & UX for cognitive issues
- Suggestions include: per‑message start/end times or expiry, visible message timestamps, default “fallback” messages, and explicitly reminding the user of their condition.
- Others warn that persistent written notes can cause obsessive rumination; the ability for caregivers to remotely remove or update items is seen as crucial.
- Several doubt effectiveness for some dementia cases where the person would not remember to check the display at all.
Technical implementation themes
- Discussions cover kiosk browsing on Android, auto‑refresh web dashboards, basic local web servers, and reliability tricks (auto‑reload, watchdogs, periodic reboots).
- E‑ink specifics: slow refresh and flashing on color panels; better performance on grayscale; debate over burn‑in vs. ghosting, with some vendors recommending periodic full refreshes.
- Frontend details: lack of native CSS “fit text to container,” JavaScript workarounds, and mentions of container queries and layout frustrations.
Security & “tiny backend”
- For the web UI, simple HTTP basic auth over HTTPS is suggested for small, fixed user sets.
- Some recommend using Google Sheets or similar as an easy “tiny database” backend.
