How I built Timeframe, our family e-paper dashboard

A decade-long personal project building a family e-paper dashboard called Timeframe, evolving from a Magic Mirror LCD to jailbroken Kindles, then Visionect e-paper displays, and finally a 25.3" Boox Mira Pro with real-time updates. The system aggregates calendar, weather, and smart home data, with Home Assistant now serving as the primary data source. Key architectural decisions include removing the database and Redis from the Rails backend, using file-store caching, and a status-indicator design philosophy that only surfaces actionable information. The project remains a work-in-progress with hardware cost and distribution challenges still to solve.
