Raspberry Pi Document Camera

This project aims to provide a simple alternative to commercial document cameras. Document cameras are used for presentations in schools, among many other things. These devices are often quite expensive and not portable. This is why commercial document cameras are not suited well for use in a school environment and why I started this project.

General

This project is based on the Raspberry Pi Camera and the Adafruit PiTFT. This camera offers several ways of interaction:

• A live preview sent via HDMI or a network
• A display attached to the Raspberry Pi which also supports user input
• A web based user interface; this can be used in conjunction with many devices.
• Wifi connectivity; the web interface can be used with smartphones, tablets and laptops

A major advantage of this document camera is it only requiring a power cable. All the other connections are optional and not required for effective use. The power can also be supplied from a USB power bank. This means the camera is completely portable.
