Free And Open E-Reader From The Ground Up

Although ebooks and e-readers have a number of benefits over reading an analog paper book as well as on more common electronic devices like tablets, most of them are locked behind proprietary systems like Kindle which make it difficult to take control over your electronic library. While there are a few off-brand e-readers that allow users to take a bit of control back and manually manage their files and libraries, there are few options for open-source solutions. This project aims to provide not only a free and open e-reader from the hardware to the software, but also a server to host a library as well.

The goal of most of the build is to keep everything as FLOSS as possible including the hardware, which is based on a Raspberry Pi compute module. The display comes from Good Display, which includes a built-in light and a touchscreen. There’s a lithium battery to power the tablet-like device with a number of support chips to charge it, handle the display, and interface with the Pi. On the software side, the system uses MuPDF which has support for most ebook file types while the server side is based on Calibre and the Open Publication Distribution System.

A subsection of the build log discusses a lot of how the code works for those looking to build their own similar system based on this project. The project code is even hosted on GitLab, a more FLOSS-y version of GitHub. Free and open ebook readers have been a goal of a number of builders for some time now, as we’ve seen projects going back at least a few years now and others that hope to make the Kindle hardware a little more open instead.

Hack The Cloud!

The obvious rants against software or services “in the cloud” are that you don’t own it, your data isn’t on your own hard drive, or that, when the interwebs are down, you just can’t get your work done. But the one that really grinds my gears is that, at least for many cloud services, you just can’t play around with them. Why does that matter? Well, as a hacker type, of course, I like to fool around, but more deeply, I feel that this invitation to play around is what’s going to grow up the next generation of hackers. Openness matters not just for now, but also for the future.

Of course, it’s unfair to pin all of this on the cloud. There are plenty of services with nice open APIs that let you play around with their systems as much as you want — witness the abundance of amusing things you can do with Twitter or Twitch. Still, every day seems to bring another formerly-open API that gets bought up by some wealthy company and shut down. I built a nice “is it going to rain today” display out of a meter-long WS2812 strip and an ESP8266, but Dark Sky API got bought up by Apple and is going dark soon (tee-hee!) leaving me thinking of how I’m going to get easy weather data in the next few months.
