Shyloo Posted February 2, 2021 Share Posted February 2, 2021 Raspberry Pi Pico Powered Open Source E-Book Reader The Open Book Project from Joey Castillo is an amazing piece of work, a DIY open source e-book designed so that anyone can solder up their own reader. The project has been with us for some time, and the past version has been based upon a SAMD51 processor commonly found in newer Arduino boards and Adafruit Feather boards. But in a recent tweet, Castillo has unveiled an early render of a version based around the $4 Raspberry Pi Pico. The Open Book Project The first thing to hit you is just how detailed the PCB is for the Open Book Abridged Edition. The silkscreen printing of the PCB tells us about each component, the GPIO pins used on the Raspberry Pi Pico, and more about the project itself. Featuring a 4.2-inch e-paper display, micro SD card storage, and a built-in battery charging solution, the Open Book Abridged Edition has space at the top of the board for the Raspberry Pi Pico. This space is designed for use with the Pico's castellated edges, enabling it to be soldered directly to the PCB with no need for header pins. Is this just an e-book reader? Chiefly yes, but the Open Book can be used with external components that use the I2C and STEMMA connector, so it can also be used as a display for sensor-based projects. i've designed so many versions of the open book now, one could call it an obsession. I'm chasing something — a buildable, grokkable, accessible, useful gadget — yet the more I learn, the more I can see where each attempt has fallen short. so. let's see how this one falls short There are no details on price or availability for the Raspberry Pi Pico version, but previous versions of the board retail for $15 on Tindie, of course, we then need to source our own components Quote Link to comment Share on other sites More sharing options...
