A standard linear regulator is not a good option as it burns off power to reduce voltage from 12V to 5V (but great for warming cold fingers).īeing of a basically lazy nature, I did try a few other options first, including a generic adjustable power supply from China. There is no power option other than using solar panels, which really struggle in these northerly latitudes during the darker depths of winter. I needed a super efficient 1 Amp power supply for my autonomous weather station that lives in the middle of a field on a small island in the middle of the Irish sea.
Sometimes buying a ready made power supply is just not good enough, especially if we want something special.
