If you have been interested in a YBox2 kit, or already have built one, here are two more things you can do with it

And From O’Reilly Media, the YBox2 is considered as a hardcore DIY e-reader platform:

YBox2 — For the ultimate DIY experience, the YBox2 platform is a pile of electronic parts you solder together and assemble in an Altoids tin. It doesn’t come with a touch-screen, or any screen at all: you connect it to a television or monitor. It uses the tiny Propeller chip, which powers many hobbyist devices and small robots. Like the Chumby, YBox2 comes with networking capability but little storage, and would need to stream book content from the Internet. The networking isn’t wireless and of course there’s no handy rechargable battery, but if you are the kind of person who can build a YBox2 you probably know how to make those too. I am not that kind of person.
