[aprssig] Low-cost weather station

[Scott Miller]

I think without the humidity and pressure sensors it'll be competitive 
with the AAG 1-wire station - and with the sensors, cheaper than the AAG 
station with the equivalent sensors added.

It should leave me with several cubic meters of space left over in the 
container, so I'll be looking at other stuff I can get at the same time. 
  Lots of cables, for starters - those are expensive to ship in small 
quantities.
