Signal Researchers Repurpose Discarded TV-Box Devices Into Low-Cost Computer Labs for Schools

Summary

Researchers built a sustainable, low-cost desktop virtualization infrastructure by repurposing confiscated and discarded TV-Box devices, originally destined for disposal, into ARM-based thin clients running a compatible Linux distribution. The setup pairs these repurposed devices with a refurbished Linux server to create functional computer access points. The project targets educational institutions with limited resources that struggle to expand or maintain computer laboratories. The approach is framed as aligned with circular-economy principles, promoting hardware reuse to reduce electronic waste while supporting digital inclusion. The paper describes the system architecture, the device repurposing process, and results indicating the approach is a viable alternative for sustainability-focused digital education initiatives.
