  • From RSS to My Kindle
    Very neat. I've been doing this with Calibre (https://calibre-ebook.com/), which involves plugging it into your PC via USB. Simple RSS feeds work with little configuration, and more complicated news sites require writing a custom python "recipe". This project uses Amazon's email gateway, which I think is limited to 25 articles per month (don't quote me on this). - Source: Hacker News / about 2 years ago
