At the request of netizen curelfox, this post talks about honeycomb coils. Honeycomb coils are rarely seen nowadays. Their appearance is roughly as shown in Figure (01).Figure (01) The insulated wir
The electric car's headlights are not on, but the horn is ringing. There is a 60V voltage at one of the two control circuits on the headlight circuit board, and the normal state of the circuit is 0V a
Now the project needs a DCDC step-down chip that can reduce 18V to 12V and output current up to 3A, and the peripheral circuit is required to be relatively simple. Now I use LM2576-12, but this chip g
I don't know if the description in the title is accurate. For example, there is a microphone. The normal output signal is 1V. When there is sound, it fluctuates up and down. In general, a resistor wil
