Comment Post #280463 I do see what you mean. And the train line seems to be "only" 25kV. Since 700kV is 28 times more, I also think that the story could be true.

Answer A: Why isn't voltage of electric chair higher?
After some research I found some reasoning behind the voltage range: 1500V is sufficient to destroy the somatic nervous system, which is responsible for consciousness and feeling of pain. After applying the voltage, within 4ms the subject becomes unconscious faster than the nervous system can regi...

Comment Post #280450 @Andy aka I think usually witnesses are required. I was thinking that perhaps some regulation forbids being near/in the same room with certain exposed conductors that are high voltage or such. Perhaps some other aspects as well

Comment Post #280456 The effect is not immediate, it takes up to a minute, hence the question. And if you have to start the answer with 'I don't know', consider not posting anything

Question Why isn't voltage of electric chair higher?
I recall vividly a story told by my grandfather who worked with high voltage power lines. A worker drove heavy machinery into 700kV line and then jumped out of the truck, instantly combusting upon touching the ground. I recently read about executions by electric chair, and got curious as to what v...

Comment Post #279967 @Olin Maybe you need a website just for yourself? It seems that almost nothing is to your satisfaction.

Comment Post #279804 +Lundin. Just because something is not covered by site policy does not mean it is off-topic. That is something you came up with.

Question 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...

Comment Post #278854 The guy who closed it clearly said he would migrate it to a more suitable section once we had it on codidact. So in his mind lack of detail certainly was not the problem. Quote: "when we get a site that covers computer hardware from user's or IT's perspective, this question would fit there very well....

Question Why are posts that users clearly approve of being closed?
One of the most annoying things about stackexchange has always been the borderline fanatic post closing or duplicate marking. Another question in meta was posed some time ago about the added value of this site. Olin pointed out that "This site grew out of frustration with how SE was managing their si...

Comment Post #278821 You have a wonderfully informative post, and it is just shut down. And it does not disappear, it is just shut for people to add more information. Currently we have people that are very experienced here and can add great value, and yet the decision is made to close this. For what? This is just purely ...

Comment Post #278821 @Nick Alexeev Really? This is a great question, falls within EMI field. This question closing fetish should stay on ee.stackexchange.

Comment Post #278602 @manas Right, you came looking for information, read something you found not to your liking and decided not to read on. You won't finish many books that way. The answer is honest and probably accurate in real life. There is a man from US that I don't agree with in general, but he had a good quote: "F...

Comment Post #278420 What would you suggest as a step up from ATMega328p? I have seen STM32 being in the spotlight, but it seems like a huge jump.

Question How to define Vsat for MOSFET as a switch?
I was looking at this design: Image alt text It uses MC34063 as switching controller. I wanted to adapt this circuit, and I was busy trying to pick R1 value. The datasheet has following formulas:Image alt text The issue I have is with calculating ton/toff, since Vsat is defined as saturation vol...

Question Design considerations when using a wireless charging battery pack
I want to include a wirelessly charged battery pack into my design. However, I am worried that the wireless charging could damage my main logic board. What considerations, apart from not having loops in main board, have to be taken into account when making design? Are there any specific pitfalls to a...

Comment Post #276408 The diode is in fact a schottky with a 500ns recovery time. Both capacitors are rated 50V, both X7R. I replaced input and output capacitors with the same rating 10uF capacitors. The noise is still present, but after touching each component with tweezers, I felt most vibrations from C1 (output). I wil...

Comment Post #276403 The EN_25V is just a name for me to remember what it does, it actually has only 5V on there. But I see that it can be confusing. I am loading numitron tube segments, which each takes 0.5mA at 25V. Regarding the inductor, I chose another one because the recommended one was out of stock. I will try wit...

Question Humming noise from a boost converter's inductor
My step-up converter makes audible noise both with and without a load.I am almost certain it is the inductor, because when I hold my finger on it I can feel vibration and it gets quieter. Unfortunately, I do not own an oscilloscope and cannot inspect what is going wrong. Here is the schematic: Image ...
