The world of newspaper readers is a merciless world. Between Kobo, Kindle, Chinese tablets or the proprietary formats of e-books and their DRM, it’s hard to choose.
And besides, it costs money. But if you are a true advocate of free software, you will love this project The Open Book Pen which is a free hardware-based device that allows you to read your e-books without any capital restriction. What’s more, when it breaks, since you’re the one who made it, you’ll be able to repair it.
Originally, this Open Book is based on a SAMD51J19A microcontroller, an ARM Cortex M4 processor with 512 KB of flash and 192 KB of RAM. On its GPIO port, you can connect a black and white electronic paper display, a micro SD slot, a jack port… etc.
The project’s Github is located here and gathers the list of hardware to buy, the documentation to build your Open Book and the flash software.
