A: ATX Computer Power Supply Spark in Non-computer Application Do you supply the PSON# signal before or after the main power comes on, or before connecting the load? Looking at the datasheets, the correct sequence is VAC power on, then PSON# signal to ground, then DC rails come on. Your load should be connected before PSON signal is taken to ground, because thi... (more) |

A: micro-RF connector crimping options I've not seen them sold separately through distributors like Mouser and such, and have not seen any hand tools for these. I found this document and this video - it looks like the machines are semi-automatic and you need to inquire with the manufacturer directly regarding availability and price. (more) |

A: Using arc trace routing instead of 45 degree trace routing Olin has a great answer, I just wanted to add some of my personal experience. I only started laying out PCBs three years ago, and I use KiCad. KiCad got curved traces support in test version 5.99 over two years ago, and I immediately started using that build because I was fixated on the aesthetics of... (more) |

A: Testing instrumentation amplifier with differential signal One of the reasons to follow the advice of your instructor is that page 17 of the datasheet identifies the need for ground return paths for input bias currents. Your initial setup may or may not work depending on the specific function generator and its output settings, because there is no current flo... (more) |

A: Pick & place file generated by Altium does not match the actual component rotations/positions Does your produced CPL file correspond to the Altium layout, or to what Eurocircuits Assembly Visualizer is showing? Open the CPL file in Excel and check. If the Altium output is wrong, I'd say check your output settings when you are producing the CPL file. If Eurocircuits Visualizer is wrong, check... (more) |

A: Siglent1104 oscilloscope channels lagging Olin's response covered everything I would do in your situation as well. If the problem doesn't follow the probes and doesn't go away, I wonder if due to only two A to D inside the scope, this is the switching delay from primary to secondary channels? (more) |

A: How can we grow this community? I am a little late to the discussion, but I think I can provide yet another perspective. I found my way to this community via searching advice on improving my schematic clarity and found Olin's $tack answer. The quality of the answer led me to opening their profile, where I found the link here a... (more) |

Thank you for the great write-up. The new diagrams you have added after Olin Lathrop's comment are much more clear and well drawn. (more) |

Tombstoning can still occur with a filled via, as it has to do with one SMD pad having a higher thermal mass due to the presence of the via. (more) |

A: Motor Controller - What might be the purpose of these resistors? I have watched multiple teardowns of this module, it is, as you have guessed, a capacitor discharge resistor network. The smoothing capacitor in this module is 550+0.68+0.68 uF 430VDC rating. Peak dissipated power is going to be 40W, less than 1W/resistor. (more) |

A: What is this metal panel under power lines? It is a passive microwave/radio repeater. They were used as an economic way of getting around line of sight obstacles. I came across the information on these researching a way of passively linking an above-ground radio network with another one underground (we went with passive yagi-coax-yagi). My gen... (more) |

| Question | — |
Battery voltage: to boost or to connect in series. Background. I have a legacy battery system that is comprised of twenty-four 12V Li-ion battery modules (self-protected), enclosed in a shell with the charging connection provided as a common ground and 24 individual non-isolated charger connections. The 24 Li-ion modules are connected in paralle... (more) |
