The concept of the project is to develop a 3D printable, Raspberry Pi based tablet. All parts (components) must be easy to obtain and readily available. It must have a battery, and it must be the primary source of power (meaning, it will charge up with a cable plugged in, but must have enough power to run without it.) It must be able to operate perfectly fine without a keyboard (meaning, everything in the user interface should work without an issue even if you don't have a keyboard and mouse plugged in.)

This project uses the Raspbian OS for now, until I can find a more suitable "touch-first" solution.
