The idea is simple. Take advantage of digital tools for education. Be it for rural education or emergency education for refugees.
First of all. I haven’t tried this setup. So it has to verified first.
The idea is to use a low energy but long life projector with an attached ?chromecast for streaming. The content could be educational videos, lessons or why not spoken books.
After some testing I would rule out the chromecast since it complained about lack of internet connection. But I’m sure there are other similar alternatives.
All this streamed only from a single android smartphone.
If this works then why not have drop in lessons. With videos running all day and all week.
