What 'Essentials' Electronics Topic would you like to Learn More About?

sorry for the Spelling,  Yes I meant Schmitt Trigger,

What I meant was that there are numerous Such Circuits in Analog , Power and Digital Domain which are standards that can be found in electronics. In fact Many of the Hardware equipments implements them in pretty standard way.

An Essentials article with the following,

Their Circuits, Basics and Implementation strategies, i.e. where are they applicable, how to use them, benefits, standard IC to perform the tasks, etc, would be an Awesome Tutorial.

The problem with your suggestion is that whilst it would be useful the "Essentials " format is for a very short article followed by a multiple choice questions. The best source I can think of to answer your purpose is the "Art of Electronics" 3rd edition by Horowitz and Hill. (About 1200 pages and not free).

You could do an essentials on, for example, Schmitt triggers - for starters there is a Wiki article :

I'd be tempted to ask for an Embedded USB essentials, but would it be too broad a topic?

Keith Armstrong's EMC for Printed Circuit Boards has some pretty good guidelines, and is available online.

Coming from the chemistry side of batteries it is interesting to learn more about the control systems for them; however, I have one major criticism to the article.

"The space between the electrodes is filled with liquid electrolyte, which have dissolved compounds that can conduct electricity." 

This is not correct. Your electrolyte should no be conducting electricity. It conducts ions not electrons. If your electrolyte conducted electricity the battery would short circuit and lead to thermal runaway.  It is true that as an ion that passes from electrolyte to the electrode the ion will accept an electron, but it comes from the load/power source depending if it is discharging/charging, respectfully.

The point of a battery is to utilize the electrochemical reaction by diverting the pathways of the electron transfer and its coupled ion transfer.  Electrons move from electrode to electrode through the Load or Power Source (corresponding to a discharge or charge) while ions move from electrode to electrode through the electrolyte barrier between the electrodes.

Again, It was an interesting priming article to Battery Management.

Great intro. Glad you picked a single line to walk thru it instead of looking at many lines and confusing the message.

like to have courses on how to sensor errors and how to fix them

- MCU such as ESP8266, ESP32, STM32 ...

what do I do? 1 - 3 have been very product oriented. I propose a deep dive into processor theory. From the start to the forgotten. Including the good, the bad,  and the ugly. In other words, what are they and how they work?

Today all we know is well this is the thing (like an Arduino). There are a few of us that want to know whats in the thing, and how does it work. (no not the physics). My minors were comp/sci and electrical engineering. My employment with Interdata / Perkin Elmer previously gave me great insights into both 16bit and 32bit architectures (both built out of AMD bit slices). Later in life, while I was working at Hughes Aircraft in LA. I worked with satellites that used custom cpu set built from 2901x, and also gave the "Mick & Brick" (how to build a desktop IBM 360) Class, at TRW. 

BTW: The banner pic from BYTE Mag is the aftermath of a cat and his hand-built (wired) computer. The funny thing was that while hanging off the table, it still worked.
