@Circuitfantasist Yes, so I often make a note to my answers in forums, saying something like the following: (1) My answer might get out of date soon, so I would try my best to make it a "live" answer, in the sense that whenever I see there is something new that make my answer no longer applicable, I will an update. Usually I will go back to my old answers and see if new Rpi version updates, say Rpi4 still works in my old answer for Rpi3.

(2) Of I would update for my answers with old devices, say if I see PIC, Arduino answers cannot do thing by Rpi, STM23 etc, or 8 bit ADC MCP3008 should be considered by newbies for a new project using 10/12/16/24 bit ADC etc. Often I add a note saying，eg. "Thought I am explaining how to operate 8 bit MCP3008, I don't want to mislead newbies that mcp3008 is the best. Actually it is the worse, ... But usually the old school elites would become very angry and made my answers disappear ASAP.

@Circuitfantasist Yes, my Blogger posts are very organized. I tried to label them to make them easier to search and group. Another way is to set up a new blogger account, eg, AD5933 blog only for this device. This is why I originally in CD, asked the question, "How to plot the I-V curve?", and even give all the details I have researched, the hardware setup, why I failed etc, so a the SO say, laser sharp focus on the problem, ...

Ah, morning tea time. See you later. Cheers.

Ah I gorgot to give an example, a short answer in python: quora.com/Why-does-Python-not-have-a-switch-statement.

This is an example of the Q&A about Tunnel Diode in Quora. The author gives a short answer in Quora and links a long article in his Blog. This is what I am considering doing:

Short answer in EE SE Q&A, with a link to my blog's long answer, which I am update/edit as often as I wish.

An article on how to finish your blogger project: tunneldiode.blogspot.com/2020/12/…

Now I have found the two articles by Hackaday's Yapo best answer my question: "How to plot a tunnel diode's I-V curve, especially in the NDR region?". I would give 10/10 marks for Yapo, and -10 marks for ALL the fake, rubbish non answers in CD.

TL Fong, thanks for the valuable thoughts! I completely share them; I have been using some of them for a long time. But in SE EE I had problems quoting my materials because they qualified it as "self-promotion"...

Last night I wrote a short answer to your question where I explained the behavior of the tunnel diode in a fun way. I hope you like it. I will make a copy in my blog too. Cheers!

Here is the copy - circuitstories.blogspot.com/2020/12/…

@Circuitfantasist Ah, about self promotion, you remind me one thing related to Olimex: (1) fongheart.blogspot.com/2013/09/from-bulgaria-with-toy.html, (2) tunneldiode.blogspot.com/2020/12/olimex-ecgekgemg-modules.html. Question: I remember Olimex was established by some university academics in Bulgaria, but I forgot which University. Do you know which one?

Interesting... I have never heard about it... How could I have heard like me dealing with basic ideas from the 19th century and they with miracles from the 22nd:)?
