A Raspberry Pi-controlled book scanner @Raspberry_Pi #piday #raspberrypi

Quill 1 467x700

Wonderful pi project for book lovers up on the RaspberryPi.org forums! From RaspberryPi.org.

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.
