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

Posted on March 16, 2021 by james

All the glazing is now done on the new greenhouse; vents and the door are fitted and only a few small jobs remain. The most important issue for the moment is probably that the door can flap about (yes, that … Continue reading →
