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.
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.
