	laptop DC power switchover unit for mains or solar PV plus 12V LVD low voltage disconnect plus optoisolator sensors and USB digital input board constructed on stripboard and in transparent plastic boxes closeup 1 DHD.jpg (Mechanoids) All my own design and construction! The LVD circuit using a MAX8212 voltage sensor and a P-channel high-side power MOSFET is the first time I've actually used a FET this beefy.
