A week on solar energy

A week on #solar energy, 70% of our consumption is solar-generated. Battery (BYD HVS 7.7kW) is ordered but 6-8 months to deliver, which I am told is β€œthe new normal” Export of energy has been set to 0%, the inverter regulates production to match consumption.

SMB20 Geiger tube

SMB20 Geiger tube

Received a SMB20 Geiger tube to replace the J305 I had on my Geiger Computer project. Should work much better outdoors, the J305 goes crazy on sunlight. Works well after adjusting the CPM to uSv/hour constant, see more here https://cs.stanford.edu/people/nick/geiger/
