ADT Inc. of Houston, TX, has put together an inexpensive, computer-based educational information resource that allows students in developing countries to access a vast library of educational content without relying on the Internet. The device can be used in the classroom, at a library circulation desk, or in an office.  The developing world faces numerous obstacles in bringing prosperity and a good life to all its people.  This device is one small step in this long journey.

 

The heart of the system is a low-cost, credit-card size microcomputer, the Raspberry Pi (RPi), a fully functional computer with all the capabilities of a typical laptop computer:  wi-fi communication, USB and Ethernet ports, and RAM memory.  Educational content can include books, workbooks, journal articles, school textbooks, videos, and whole programs of class lectures.  Students and teachers access the RPi using any wi-fi-enabled devices, such as a TV, monitor, projector, laptop, desktop, or tablet computer.  Students can use the materials for individual research and learning or together in a classroom setting with students using wi-fi-enabled devices.
