I have thought about that but to my knowledge it doesn't have any 3D
functionally as KiCAD does.
I'm not sure how full fledged the 3D aspect of KiCAD is as it is very
useful when design the 3D CAD models as you can work out clearances for
the PCB easily.

Just for reference I'm dyslexic so unfortunately there will be others,
I'll do my best to make my email understandable but the occasional one
will slip though.

This isn't a commercial venture, it's just to see if all the tools can
be used together and produce something and I'm doing it for fun.

That interesting, I could see about specifying a very powerful chip so I
could add bindings for other languages but that's out of my depth I'm
not sure if that could be done.
One of my far fetched add-ons to this project was to make them wireless
and create a mesh network so multiple units could be put on a site and
give weather profiles to be used in micro weather forecasting.

I'll have a look at those when I specify everything up but initial idea
is to keep it fairly simple and use my existing knowledge.
