David Hamp-Gonsalves created a really cool use for your old Kindle:
Second hand Kindles are waiting in drawers for someone to repurpose them into something great. Boasting large e-ink screens, wifi connectivity and ARM processors they are an amazing hacking platform.
In my case I created an information panel summarizing my day such as my calendar, surf and weather forecast, garbage schedule, school closures, etc. My favorite part is that any extra space is filled with a random Pokémon sprite which my kids(not me) like to come check in on.
Built with Rust plus some serverless backend data collection bits.
