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

说明与用途

“Light don go”工具检测到停电后，弹出全屏提示，提供60秒伸展计时器和活动建议，减少尼日利亚停电期间的工作时间损失。

问题

Power cuts in Nigeria cause laptops to switch to battery, leading to lost work time while waiting for a generator to start.

结果

The tool runs offline, uses a local Gemma model, and reduces lost work time during power cuts by prompting users to take short breaks or go outside.

工作流

• Detect battery state via psutil every 5s
• If battery >30s, show full‑screen page with plan and timer
• Provide activity nudge from Gemma 4 E2B via Ollama
• Guard checks nudge for numbers or forbidden words
• If guard fails, use fallback sentence
• Close page after next power cut
• Log events and save weather forecast offline

证据

When my laptop switches to battery for more than 30 seconds, a full‑screen page opens on top of whatever I'm doing

The model is a 4.3 GB download. My laptop is an i5-1135G7 with no NVIDIA GPU.

来源

I set keep_alive: -1, which keeps Gemma in RAM (3.9 GB of my 15.7).
