Good man!
You're a good man Chris! This the last piece complete my small contribution to the Home Built MM brigade.
Just by looking, it shouldn't be too hard to figure out the capping on this. Something that would keep as much liquid water out as possibly, but still allow good air flow. I think it would be directional in nature. Wind blown rain from behind the unit would be an issue, but as long as you were moving or pointed into the wind it would keep the majority of the water out.
I'm also having some issues figuring out how to mount a 12V DC fan in the tube. Actually finding a fan small enough is more a challenge than mounting it.
Last, but not least is the configuration of the sensor array. Since I'm using a David Weather Monitor II, I only have the single temp sensor (Temp/Humidity will be aquired in the near future). Do you simply let the sensor fall free in the tube? Do you mount it with a spider mount (similar to telescope mirrors)?
Basically, the whole smash. I hate reinventing the wheel when there are so many that have already done it. Besides Chris, would anyone else care to share your diagrams/experiences?
