I think the bullet list in the current on-topic page is clearer and easier to understand. Admittedly, there are some "confrontal" bullets, but that's OK in my point of view. Sure, there are always...
My biggest concern is that it will get too random and low quality. The worst that can happen is something similar to SO's failed "Documentation project" a couple of years ago, where users were to w...
Hi, I built a constant current load following the circuit from https://www.instructables.com/id/DIY-Constant-current-load/ But my op amp gets destroyed after a few minutes. The transistor or the op...
Personally I wouldn't want another category (what you seem to mean by "section"). I also don't think this should be a code review site. However, asking for validation and advice on small and spec...
I think your grandfathers story is, shall we say, apocryphal. You should know that electrocution kills by stopping the heart (or causing fibrillation), and the heart must be kept from beating long...
What is your best suggestion for building a follower that would ideally satisfy the following spec: frequency: from 100 Hz (or lower) to 1 GHz input signal impedance: 1 Mohm input signal ampli...
What is causing this [ABC-news video via Twitter] spectacular power-line phenomenon? [image: still from ABC News]
Can we make a n-bit subtractor using full subtractors or if we want do subtract one binary from another we must use full adders and use the complement of the 2nd number to do the subtraction? I ha...
I have designed a graph of the current in a photoresistor related to the brightness of light which hits the photoresistor. Our professor told us that it is more correct to draw the Current/Brigh...
Please, have a look at this thesis, from P. 12 to the end. The bottom line is that the Buttler-Volmer equation, which is in fact equation (13) derived in P. 12 to 16 (called by the author the elec...
Problem pH electrode buffer offset appears when solution is grounded. Detail I have a pH electrode in some conductive solution (~1000uS). The output (measurement electrode) is buffered by an el...
I have been watching this video and at 3:28 it says that a induction is inherently self-starting.Does this happen because of the energy stored and released in the windings of the statorFrom 3:41 u...
In my effort to clean-up and organize tags on EE.CD I arrived at a point where there are a lot of old tags with wrong capitalization. How should I request the staff to change them? Should I post ...
For my test bench I need an inductor (aka "reactor") that meets the requirements below. I have tried to purchase it outright as a made-up item, or the parts to make it (core and windings), but have...
I have an opto-coupler circuit where is very slow turn off. I can't figure out what is the cause of this problem. It's for UART isolation, with speed 9600 baud. Datasheet: EL357NC Do I have som...
I have a bed for which the headrest can be adjusted. There are 2 separate power inputs for each side like in the picture: In addition, there is a set of 9V batteries on each side, presumably for...
I got my hands on a Tesla Model 3 aftermarket module (Display/Cluster) The IC's are labled with the brand 'PocketLink' Id like to know more about what these parts are. Chip1: PocketLink B2 003...
I always had trouble understanding the terms "digital" and "analog"; Wikipedia and various Q&A sessions didn't contain explanations I found clear. I understood that these terms aren't well defi...
I think your measurement instrument is fine. What is not is your understanding of resistance: there is nothing like this "resistance of water". In your case, the measured resistance depends on the...
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...
Currently there are $\boxed{\color{red}{\text{three}}}$ downvotes so maybe someone can explain why this has happened. Anyway, on to my downvoted answer: - You have "mentioned" the threat (the ESD ...
Let's take a look at the state of affairs for the past few weeks on this forum. For the past two weeks, some users has been posting a lot of questions, a lot of them self-answered. This is not a p...
You are asking about feedback in this circuit, and how R3 fits into that: First, note that the circuit is an emitter follower, and has a voltage gain less than 1. Second, R3 bypasses the transi...
The term "Discrete" uses to describe a signal with two modes. Wrong. Discrete means it can only take some values , not all values. I suspect by 'modes' you mean # of possible outputs. If we h...
