  • FYI, you can still dedrm Amazon books. Even ones you buy today.

    Edit: Not going to lie, it’s a lot more complicated now. But it actually works for Amazon borrowed books too (i.e. - Libby library books)

    You have to use KindleForPC 2.8.0. You download the books you want, then run an app called KFXKeyExtract28 to pull out all the keys.

    You have to have DeDRM installed in calibre and point the plugin to the keyfile that gets generated (you only have to do this once)

    Then you can import the books into calibre and everything will work as normal.

    Don’t get discouraged, it works, you just have to figure out the right workflow that you’re comfortable with.

    Also, I have no idea why they don’t just update the ReadMe, as it seems like this discussion thread is the only actual place this is documented.














  • 800w is less than half what you could pull from any outlet in the US. Standard electric breakers are rated for 15amp continuous at 120v. Most heating appliances designed to run for long periods of time (like electric heaters, or countertop cooking) run around 1800watts. So you could pretty easily plug in two 800w solar panels to back-feed a single circuit.

    50amp 220v is about the limit on one circuit for most residential homes (for ovens, or electric central heating) which is what would be used for the fastest electric car charging at home.

    That’s plenty of headroom for in-circuit solar generation.
