suppressor diodes on the rain and wind inputs.

it's not perfect.

in a white flange mount ABS enclosure, and will have a port near the
humidity, temperature, and baro sensors, which are all along one edge.
It'll either be narrow slits, or a larger port covered with a metal mesh.
It'll need to be kept out of direct sunlight and should be in a
semi-protected location. A pagoda would be nice, but it was going to be
too expensive to manufacture. Even using an existing pagoda would
require making a custom enclosure to fit it, which would be a few
thousand bucks for tooling. Maybe I'll do that in the future if I sell
enough of these things.
The files went off to the board house this morning... I should have
something to show in a couple of weeks.
