Notes and links from Sat 11 July

Status: Before the heatwave I ordered a cheap solar powered extractor fan. Today, as the heatwave enters its final stages, the fan arrived. (No problem with the delay - it’s hot out there!) But there’ll be another one along in a few weeks I’m sure, so it’s not wasted. As is often the case I misread the measurements and thought I was getting as 12" fan but of course it’s 12cm, which is fine but quite limited in the amount of air it pushes through. It’s not going to work as a people-cooling fan in the dome, but it should fit nicely in the shed where it can pull out the warm air and make it nicer for the rabbits. Looking forward to fitting that once the heatwave fully passes. While it only generates 12v it’s also the first modern solar panel I’ve gotten to play around with, which is quite exciting in anticipation of the plug-in revolution to come. I’ll doubtless be trying to wire it to all manner of low-voltage gizmos over the summer. Interesting how it seems to need sunshine on the…
