[aprssig] 36v inverter

[Scott Miller]

Here's the wind sensor assembly (minus the rain gauge):

I've got the first batch of prototype boards for the station coming in 
on Thursday.  It's a flange mount ABS box with temperature, barometric 
pressure, and (optional) humidity sensors.  It'll connect directly to a 
radio (the processor is the same as the OpenTracker+ RT), it'll output 
Peet Bros format (and maybe some others) for connection to a PC or 
external TNC, and it's got a second serial output so you can daisy chain 
an indoor and outdoor unit.

I gave up trying to make it a through hole kit.  The baro sensor 
selection in particular was limited, and it was going to require too 
many components.  Going all SMT cut the cost considerably and left 
enough space for ferrite chips on all off-board connections and 
transient voltage suppressors on the wind and rain sensors.
