Who in the world would have the expertise to operate one of these? In a “low resource” high school? The problem isn’t (just) having the equipment.
There are so few teachers with enough knowledge to engage. Well-resourced, highly motivated kids might be able to read on line, but that’s a real stretch for the rest.
If I understood correctly they mean that these uplifting stories end up not panning out and it’s more about publicity than accomplishing the thing. I’m genuinely curious about the kind of SDR that works for a price like this and how you fit it into a $500 BOM.
