A small website used to display current time, date, weather, forecast & upcoming birthdays on a Kindle Paperwhite as described in my blogpost.
Warning: This code was neither written to be easily adapted/customized nor for a "modern" browser as you know it. The Kindle Paperwhite's "Beta Browser" comes with several limitations, which is why there are some ugly passages in the source.
That said, I tried to keep it simple and lightweight. Also, I'm rather a devops guy than a frontend developer, so there's nothing too fancy around here.
Edit the js/config.js to contain your OpenWeatherMap API token, birthday dates and other desired changes.
Afterwards, fire up a webserver somewhere (on a Raspberry Pi, e.g.) and let it serve your code, like so:
docker run --name kindle-infodisplay -p 80:80 -v [PATH/TO/CODE]:/usr/share/nginx/html:ro nginx
You need a webserver because the Kindle Beta Browser does not support the
file:///protocol. Otherwise it would be possible to put the source files on the Kindle itself, of course.
