@VictorVenema Hmm, it's definitely worth thinking about. There's lots of people though that would gladly give their thoughts for free if asked. Maybe there's an opportunity helping people connect.
@SteveSawczyn I am on a committee to create a global climate reference station network. https://rmets.onlinelibrary.wiley.com/doi/full/10.1002/joc.5458
If someone in the open hardware movement were interested in creating instruments for such a network, I would be happy to support that and try to get this group to support that.
Even if I like working with my hands, I have been a computer scientist for my working life, to try to pull something like that off myself would be overly optimistic.
