Posted on November 18, 2021 by james

The rain gauge dismantled

Posted on November 18, 2021 by james

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 →

My rain gauge died again :(

Posted on November 18, 2021 by james

A short while ago my AAG 1-wire rain gauge stopped telling me that rain had fallen at all. The 1-wire device still shows up in Linux and is readable, but the 1-wire counters never change. I’ve checked by dribbling water … Continue reading →

So it’s not summer any more then?

Posted on June 17, 2020 by james

Restoring an AAG rain gauge #2

Posted on January 29, 2020 by james

I’m pleased to say that the rain gauge is now in place and all connected up. It appears to be counting properly (unlike it did when I had it on the desk for testing), but I’ll keep an eye on … Continue reading →
