The solar-powered digital library device called SolarSPELL.

History

SolarSPELL was created by Laura Hosman, a professor at Arizona State University (ASU), in 2015.^[4] Hosman's students were involved in the creation and testing of multiple iterations of the SolarSPELL device.^[1]

Hardware

The SolarSPELL digital library device consists of a waterproof case, a solar panel, a lithium-ion battery, a voltage regulator, USB cords, a Raspberry Pi, and an SD card. The SD card stores pre-selected educational content for the users to access.^[4]

Projects

The SolarSPELL library is used in 15 countries in Africa, the Middle East, the Pacific Islands, and North America.^[2] As of 2024, SolarSPELL has deployed 597 digital libraries and trained over 960 individuals how to use the technology.^[3] They are estimated to have reached over 300,000 people with the contents of their digital libraries.^[2]

The SolarSPELL library is used by students and teachers in classrooms that may struggle with access to resources. In one study, after a SolarSPELL was used in a 10th grade biology class at Simon Sanchez High School in Guam, there was significant improvement in learning and education for the high schoolers, including for youth with special needs. The use of SolarSPELL in this class resulted in higher-than-average biology test scores and a reduction in student disruptive behavior in class.^[5]

SolarSPELL has collaborated with non-profit and governmental organizations worldwide, including the Peace Corps, Voice of America, and more.^[4]
