IC231 in the circuit is a common op amp, used as a comparator, IC231+ is used to monitor 12V1, IC231- is used to monitor 12VOUT, and a transistor is controlled by the comparator. When 12V1>12VOUT, Q23...
High-frequency transformer air gapThere are two ways to open the air gap: "grinding" and "padding". I use the padding method here. I pad one side first and measure it. The inductance is much smaller, ...
Washing hands can release static electricity from the body, right? So it stands to reason that urinating should also release static electricity, right? Shouldn't static electricity flow out of the bod...
