It’s hard to beat the fidelity and durability of printed text on paper. But the e-paper display gets pretty close, and if you couple it will great design and dependable features, you might just prefer an e-reader over a bookshelf full of paperbacks. What if the deal is sweetened by making it Open Hardware? The Open Book Project rises to that challenge and has just been named the winner of the Take Flight with Feather contest.
This e-reader will now find its way into the wild, with a small manufacturing run to be put into stock by Digi-Key who sponsored this contest. Let’s take a closer look at the Open Book, as well as the five other top entries.
You may remember seeing the Open Book back in October when Tom Nardi looked in on early testing for the board. It was prototyped using the Adafruit Feather, which of course was the main requirement of the contest. The controller is now built into the board for standalone functionality with the Feather header providing an opportunity for expansion.
The screen is 4.2″ with a resolution of 300×400. It reads files from a microSD card and uses seven buttons on the front of the board for user input. A dedicated flash chip stores language files with the character sets of your choice. The small LiPo cell can be charged via the USB port, and of course e-paper helps greatly in reducing the power consumption of the reader.
You’ll find a few extras on the back. There’s a headphone jack for listening to audio books, and get this, a built-in microphone and a TensorFlow-trained model allow for voice control! There are STEMMA headers to add your own hardware options, and designs for laser-cut and 3D-printed enclosures.
