As for issues with the cups going missing, now that's another story
I have read stories of Fine Offset anemometers lasting months or many years, clearly dependant on the ambient weather conditions, and how the bearing is affected. I guess you fall into the latter time bracket? Out of curiosity, can you remember what the highest windspeed gust you measured was with the Weatherduino system? Here in the UK we've had a particularly wet spring and numerous heavy snowfalls (for us) over the last winter. Guess I'm just taking extra (maybe unnecessary) precautions on the weatherproofing front.
Yes, I saw your post of the broken anemometer cups recently. Quite disturbing really.
I'll also be posting some details of a diy anemometer build from scratch with which some of my near real time windspeed measurements were done.
