If anyone wants to see the old project: https://hackaday.io/project/192688-the-open-book

Its been around for a bit. The newest iteration looks like its trying to be more like kindle.

GH page: https://github.com/joeycastillo/The-Open-Book

I forget where but the developer goes over the cost of the physical hardware a couple of years ago somewhere. Its kinda expensive to make your own open source ebook reader from mostly scratch.

I like this version: https://www.oddlyspecificobjects.com/projects/openbook/
