That circuit is drawn rather obfuscated, but it does seem to make sense: Start by looking only at D1, D2, C1, and C2. Pretend D3, C3, and D6 don't exist. Although not drawn very well, this is ...
It's been a while since I did 1-wire, so I don't remember the current levels. R18 seems rather high for supporting the minimum required voltage at the maximum possible current. Let's say for sake...
Your controller is too fast compared to the plant (the thing being controlled), thereby causing instability. The most obvious culprit is the 50 kΩ resistor between the controller output and the FE...
Now that you've supplied a link to the product, I can provide a different take on this affair. Your "UPS" is an Amazon Basics model described at https://www.amazon.com/gp/product/B073Q3BSPG/?th=1....
I see that manassehkatz has already given you a good answer and plausible explanation for what you observed, so I'll fill in a few other points. Your battery is 5 years old, so is getting to the p...
Such a domed button is usually called a "membrane switch", at least here in the US. As you say, the small metal bubble makes contact with something underneath when pressed. Advantages of membrane...
You say the only thing that will be powered by the ±12 V supplies is a comparator. The first thing I would look at is whether you really need the comparator to run from that voltage range. Presum...
I want to know why the top-of-the-line CPUs and GPUs from Intel, NVIDIA, and AMD are all bragging about the fabrication process (7nm and 5nm) and trying to be consistently smaller. It's marketing ...
What you describe is already allowed in Papers. See electrical.codidact.com/help/papers. The papers by Circuit Fantasist are well on topic. Presenting a concept in an accessible way is OK. I ha...
I agree that the particular question was correctly closed. Questions about protocol stacks aren't necessarily off topic. However, this one was because nothing about it had anything to do with ele...
One of the aggrevations Elsewhere were all the vandal and retribution downvotes. They never took the problem seriously. Now it's happening here. Andy was the latest target, twice, recently. I'v...
What happens to the overall accuracy of a resistor if I implement it as multiple resistors in series or parallel? For example, can I get better than 2 kΩ 5% by putting two 1 kΩ 5% resistors in ser...
I think this could be on topic if done carefully. We don't want this to devolve into a popularity contest of everyone's favorite features. Answers also can't be about opinions of which features "...
I recommend using native HTML for lists, and most other formatting for that matter. HTML gets around the ambiguity of what is an item and what is text following the list. The list isn't over unti...
It's not clear what you are really asking, but here is something that might fit your requirements: First, R1 and R2 can be considered separate loads. The transistor therefore switches two loads. ...
I'll assume by "PMIC" you mean a dedicated switching power supply chip. Such a chip contains the PWM generator and receives output voltage feedback at a minimum. They may also include a driver fo...
A switching power supply already is inherently a filter. Current is coming thru an inductor, followed by a capacitor to ground. If you are asking what additional is usually done to filter out chan...
This site isn't appropriate for telling you what to choose. We can, however, give you information on microprocessors versus microcontrollers. Microprocessors and microcontrollers are intended to d...
It seems your question comes down to how to demodulate a SSB (single sideband) signal. Note that the single sideband is already the signal you want, just shifted by some fixed frequency. One way t...
There are various criteria that govern how well power is taken from a nearby changing magnetic field: Distance. The magnetic field diminishes rapidly with distance from the source. Shielding. Pick...
Any deviation from the example antenna could have significant and unintuitive consequences. Unless you have good antenna modeling software and good understanding of antenna physics (which you appa...
A voltage source is "heavily loaded" when something is drawing a large amount of current from it. "Large" in this context is relative to what the voltage source can deliver, or perhaps relative to...
Assuming nothing is broken or wired incorrectly, this is most likely the result of the opamp oscillating wildly. The average may still be about what it should be, so you might not notice with only...
It doesn't quite work that way. You are missing the fact that the current (which the magnetic field is proportional to) decays exponentially. You are also missing the resistance of the coil itsel...
RTOS A RTOS (Real Time Operating System) is much more than a bunch of interrupts. Most true dedicated microcontroller applications don't need any RTOS or any other kind of operating system. Genera...
