@#52987 The joke is that a grown man (woman?) is throwing tantrums because you and Olin did not support his critique, immediately taking stabs at whoever he can identify. We literally just discussed the potential downfalls of public downvotes. This guy knows I have disagreed with him in the past and ... (more) |

A: Why are there more N type than P type MOSFETs? One reason could be that N type MOSFET can switch loads that are in Drain, meaning that whatever the load voltage, you can turn it on/off directly with any microcontroller, provided that the MOSFET is 5V or 3.3V logic level. You could invert it and do the same with P-Channel, but N-Channel just feels... (more) |

@#36396 I mean alright convince the staff to make it and let's see. I think it will result in hard feelings and lots of aggression, but hey, I guess we won't know without trying. I can just imagine someone writing 'Yea, I don't know, I just kinda disagree with this approach'. And then what? How long ... (more) |

And imagine, you write another of your 'Well it is obvious to anyone' + 'Learn to read' type of posts, I will slam you or Andy every time when you berate a new user.

"Downvotes aren't for when you think it might be wrong. They are for when you're reasonably sure something is wrong, and are prepared to defend your point." -> Or when you think the answer is condescending or disagree with how it is written or if 1/2 of the answer is s***ting on the OP for missing a ...

There is no 'coming back' if they haven't even arrived in the first place. Front end design of the site is completely fine, I would even argue it is cleaner than SE. The only point I agree with is the collapsed comment threads, those are annoying. However, changing layout/colors/whatever won't bring ... (more) |

@#36396 Also note how you answered his last question, no upvote, no downvote, no comment at all. Is it clear to him now?

@#36396 Closing questions is hardly the issue here. The problem is the recipe for answering questions half of the time:
Explain to the user why his/her question is unclear/stupid/obvious, then answer anyway, then some borderline rude comments on how to improve next time.
Notice how you provide... (more) |

You haven't provided any reason we should care about impedance discontinuities by themselves. -> If you could provide a reason, it would be in favor of the curved one, and if you could provide a reason why it does not matter, it would then be in favor of square one, since it is easier to make/simulat...

@Lundin If you have some valid arguments why the antenna is not properly designed please do tell. Otherwise such question can be asked literally in response to any other design question. 'Why is this done like X?' - 'Well, what makes you think X is good?'. This does not help. (more) |

Why are antenna PCB traces square instead of rounded?

For example, ESP32: Image alt text More examples can be found online. If the important thing is ... (more) |

A: Design considerations for a synchronous DC/DC converter At some point the MOSFET approach will lose to diode if current is sufficiently high: Image alt text The drain-source resistance will cause the forward voltage drop to go up linearly. So picking a MOSFET with a small Rds would be one idea to reduce conduction losses. Checking the gate threshold... (more) |

Why is the resistance of water so high and still so dangerous? Image alt textMeasuring the resistance of water from my tap I got 500kOhm. Adding considerable amount of salt brought it down to 20kOhm: The question I have is why water is such a danger for short circuits if the resistance is so high? Is there an issue with the measurement technique, or are ... (more) |

Is there a particular type of lead-free solder that does not degrade soldering tips? I have had my soldering iron tips degrading at ridiculous rates. Granted, they are not very expensive, but sometimes it takes less than 8 hours of soldering for them to degrade to the point where they are no longer usable. I use a soft sponge for cleaning, don't leave the iron on for prolonged times ... (more) |

There is a saying: When everyone around you stinks, maybe it is you who has .... your pants.

A: Why isn't voltage of electric chair higher?

After applying the voltage, within 4ms the subject becomes unconscious faster than the nervous system can regi... (more) |

Why isn't voltage of electric chair higher? I recall vividly a story told by my grandfather who worked with high voltage power lines.

Cleaning flux out of USB connectors after soldering When soldering Micro-USB or USB-C connectors by hand, flux is applied generously. This sometimes results in flux getting inside the connector housing, making it sticky and creating high physical resistance when inserting and removing the cable. I have attempted using q-tips and small brushes with alc... (more) |
