The Open Book PCB on Tindie #ebook #CircuitPython #Feather #SAMD51 @tindie @josecastillo

Two unpopulated circuit boards, one black and one blue, each about the size of a large index card.

Back last year, you might recall hearing about an open source hardware project called the Open Book: a do-it-yourself, Feather-compatible device with e-paper, designed for reading books. Well as of this month, the bare printed circuit boards for building this project are available on Tindie!

The Open Book took a winding road to becoming reality, but it’s always been tied very closely to Adafruit’s Feather platform. The first incarnation, the E-Book FeatherWing, was an accessory board with many of the features of the Open Book, designed to pair with a Feather. The E-Book FeatherWing is still a board you can make yourself, using one of those blue PCBs. I like it because it’s a bit easier to build compared to the Open Book, with simpler parts and fewer of them to place.

The Open Book has been a passion project of mine for over a year now, and at every turn, Adafruit’s products and learn guides have inspired and informed what the Open Book would become. Early prototypes used an eInk Breakout Friend to operate the screen, before I knew how to design a PCB. Then once I learned, I was able to adapt aspects of Adafruit’s open source schematics, from power supplies to microphone preamps, into the design of the Open Book. Design cues, like the shift register D-pad buttons and the trio of STEMMA ports, come directly from the PyBadge. I even learned surface mount soldering from Collin’s Lab.

It takes some patience and a steady hand to build your own e-book reader. But once you have, you can run Arduino or CircuitPython on it, stack it with wings to add Wi-fi or GPS — and yes, of course, use it to read. The book-reading software is still pretty basic, but we’re working on it!

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
