That looks kinda like my project down to the same board. Crazy. Not sure why hes charging for it, its very simple to program. And heltek comes with a plastic casing/screen to begin with.

It looks familiar butbwith an eink screen rather than the heltek screen that comes with it. Cool little device he made.
I get the error code: 400 Bad request.
No idea. You may want to put it directly in your browser window tab. Maybe lemmy is doing something strange to the url? Its def a real link though.
That's awesome. Guess I know what I'm doing this weekend then.
Give it a shot. The code is a bit piecemeal so feel free to improve upon it. I got a book working with upload and stopped there. Its a "good enough" solution. It goes to the next page and keeps the page when the power is out.
The code could probably need a tuneup. I haven't done C++ in 10+ years other than some tiny linux kernel patches and that was a bit ago.
