A: Should I connect signal reference and chassis ground in a battery powered application? It's not totally clear from just the verbal description, but it seems the real question is when/if signal and chassis ground should be connected. If the circuit is not intended to be truly isolated, then signal and chassis ground need to be connected at some point. The trick is to think about all... (more) |

Show a diagram. I got lost in some of the hand waving. (more) |

A: Substituting multiple lower voltage resistors for a high voltage resistor Yes, this is safe, but you do have to consider the layout carefully. You have to make sure that nothing conductive gets between the pads of each resistor. For this high voltage safety purpose, you can't consider the solder mask as a reliable insulator. If a trace goes between the pads of a resis... (more) |

A: Is it possible to use two zener diodes in series back to back to replace a diac? It's not clear what you are really trying to do, but if you're trying to replace the left circuit with the right one, that's a bad idea: The left circuit switches to appear to pass partial voltage. That means it doesn't dissipate much power. Power into something is the voltage across it time... (more) |

@Andy: You should be a mod here anyway (even though this has nothing to do with this particular question). You are one of the original core group that proposed this site. I don't know how to make it happen. Perhaps the admins don't realize you were one of the original core. (more) |

I just checked, and there seems to be nothing in the mod tools to look at voting patterns at all. It would be nice if each of us could see recent rep changes, like there was on SE. I asked for that at https://meta.codidact.com/questions/276332, but was largely ignored, or it got used to malign rep ... (more) |

I added the short description for the Papers category to the end of my question. This may change if there is consensus to do so, but we have to start somewhere. (more) |

@mana: Collaboration on a paper makes sense, but we would need some new features from the system for that to work. We would need the concept of multiple authors, and a way to have drafts that only the authors can see until the paper is published. We don't want all the noise of multiple people event... (more) |

Nobody is going to get punished for writing a bad paper, unless it's clearly spam or the like. Well intentioned but bad papers will merely get downvoted to oblivion. If the author feels that is punishment, he can always just delete the paper and it never happened. That said, papers will be held to... (more) |

A: What is the added value - still unclear This site grew out of frustration with how SE was managing their sites, seemed to value clicks over quality, and lost appreciation for those providing the content that the clicks came to get. This site is not run by a for-profit corporation. There is no danger that investors will get restless and... (more) |

A: How do I calculate and manipulate the inductance and capacitance of outputs to a connector on a PCB? It's not completely clear, but it seems you are asking about a circuit in a class 1 div 2 location that will drive another circuit in a class 1 div 1 location. The point of the IS barrier is to present a Thevenin source. In other words, the two important criteria are the open circuit voltage and ... (more) |
