In 2012, faced with the challenge of delivering digital learning materials to remote communities in Ghana with little to no internet access and frequent power outages, I developed an innovative solution using the Raspberry Pi. As the sole Technical Lead at Open Learning Exchange Ghana, I designed and built a sneakernet-based mobile digital learning platform—a groundbreaking system that enabled learners, teachers, and students to access thousands of educational resources without requiring internet connectivity.

I engineered the Raspberry Pi to serve as a portable local server, broadcasting a Wi-Fi network powered by a simple 5-volt battery pack, making it ultra-portable and perfectly suited for energy-scarce environments. Users could connect wirelessly via mobile devices, laptops, or tablets and browse extensive digital libraries including textbooks, videos, and interactive materials, all hosted locally on the Raspberry Pi. This innovative approach eliminated dependence on external networks, provided instant, offline access to learning materials, and significantly bridged the digital divide in remote parts of Ghana.

The impact of the solution was profound—it won the All Children Reading (ACR) Grand Challenge Award in 2012, standing out among over 400 global submissions. Following the award, the system was scaled and deployed across all regions in Ghana, transforming access to education for countless learners in marginalized areas. My work not only demonstrated technical ingenuity but also showed visionary leadership in solving critical infrastructure problems through sustainable, cost-effective, and scalable technology.
