"Light don go": when Nigeria's power cuts out, my laptop sends me outside

Developer Dann Waneri has created an innovative local AI tool called "Light don go" to help users cope with frequent power outages in Nigeria. When the power grid fails and a laptop switches to battery, the software triggers a full-screen interface that encourages users to step away from their screens. Utilizing the Gemma 4 E2B model running locally via Ollama, the tool provides context-aware nudges—such as suggesting a walk or a stretch—without requiring an internet connection. By separating the generation of factual data from the creative nudges and implementing a strict guardrail system, Waneri ensures the AI remains accurate and helpful. The project, built for the Hacktoberfest Open-Source AI Challenge, demonstrates the practical application of small, efficient language models in resource-constrained environments, effectively turning the frustration of power cuts into an opportunity for physical activity and well-being.
