Using the awesome and powerful Raspberry Pi 2 mini PC Jonathon Duerig has created an automated book scanner allowing you to easily transform those all the paper printed versions you might own into ebook formats, that can be viewed and carried with you on your mobile devices.
The mini PC powered book scanner is controlled by a Raspberry Pi 2 and uses the new Raspberry Pi Touch Display as an interface to control the function of the scanner and track progress.
The design of the book scanner has taken inspiration from the The Archivist DIY book scanner and uses the Tenrec Builders‘ open source book-scanning software, Pi Scan. The Pi Foundation explains more :
Books rest on a V-shaped cradle that the scanner’s operator lifts up towards a similarly shaped 3mm glass platen by pulling down on a handlebar, thus pressing flat the pages, which are evenly lit from above. The Raspberry Pi controls two Canon PowerShot ELPH 160 cameras, each angled perfectly to capture one of the visible pages of the book. The Pi allows the user to set the zoom level for each camera, automatically sets and locks focus, and captures the images, saving them to an external SD card. The scanner’s touchscreen interface is made with Kivy, a Python GUI development system for touchscreen devices.
