November / December 2021 wrap-up

Let there be chairs and light – Spark Solar Trailer

Trailer update – New 12v solar charge controller feeding two 105Ah batteries, 3000w pure-sine inverter, tested with 7A power saw (dimmed light). Prompted discussion about how to partition power for more sensitive electronics. Have free 2nd 1500w modified-sine inverter that should be temporary solution (want pure sine for everything). Also added a remote switch at trailer doorway to turn inverter on/off.

11 attended virtual First Tuesday in December, talked about details of solar power charging system, Portland robotics meeting, brewing tips, etc.

Sold 4 surplus PCs via NORVAC consignment (to general fund).
