The rain gauge dismantled

I’ve now got the rain gauge down and taken it apart. Possibly I’ve posted photos before, but this is what the guts of it look like: After ungoo-ing the PCB, I’ve come up with a first approximation of the switching … Continue reading

A “Crown of Thorns” for my rain gauge

One of the problems with a rain gauge and I think something that had prevented it working properly last time was that it forms a nice little perch for birds who then, err, contrive to block up the holes that … Continue reading

My Stevenson screen has a 12V supply to it for powering the 1-wire hub that has all my weather sensors attached to it. At the moment the main 1-wire connection runs back to the PC in the observatory warm room, … Continue reading
