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

Описание и применение

Инструмент «Light don go» помогает пользователям ноутбуков в регионах с частыми отключениями электроэнергии оставаться продуктивными и безопасными, показывая офлайн‑страницу с планом растяжки и напоминанием выйти на улицу.

Задача

Laptop users in regions with frequent power cuts need a way to stay productive and safe during outages without relying on internet or external APIs.

Результат

The tool runs offline, uses local resources, and keeps users productive during outages, with a 60‑second stretch plan and safe outdoor activity nudge.

Рабочий процесс

• Detect battery drop >30s via psutil
• Load pre‑saved weather data from Open‑Meteo
• Compute sunset via NOAA formula
• Generate nudge text with Gemma 4 E2B (local Ollama)
• Show full‑screen page with timer and nudge
• Close page after user acknowledges or timer ends

Доказательства

The page works with no internet, because the router is already off: it uses no web fonts and loads nothing from a CDN.

The model is a 4.3 GB download. My laptop is an i5-1135G7 with no NVIDIA GPU. Measured: 14 s cold, 3.6 to 4.0 s warm, about 15 to 20 tokens per second.

Источник

The guard checks numbers and topic, not sense. In one test run Gemma wrote "watch the rain inside the phone", and it passed.
