    I am looking for a way to switch a circuit on with the same power source as the original circuit or a separate power source. The issue that I am having is I can not find a way to keep power to that second circuit using a relay once the original circuit switches back over. my original project...

    Help in understanding the math behind the schematic.

    Ok. little background on myself. I am a high school graduate with no formal electronic education. I read books and tutorials etc online. I think I am above the curve when it comes to understanding electronics, but where I struggle at is the design of circuits. I think a lot of this comes from a...
