This is a most excellent place for technology news and articles.
Super cool project. FYI it does require converting your ebooks to a special format.
I suspected as much since it's using an Arduino Mega - very battery efficient I'm sure, but very underpowered.
Epub, the most popular format, is a fucking website, not very efficient. And it even allows the author to set font size and stuff, i mean, use a pdf then.
