Just a quick reply.

(1) I visited circuitfantasiastories.blogspot.com. I only saw an empty web page. Perhaps you forgot to click the "publish" button at the very top right corner.

(2) About Bob Duhamel's white board and marker. Well, if you browse MIT's very recent youtube lectures, they are using black board and white chalk. But everybody thinks it is OK. Perhaps I should not say you technology is outdated. It is only the symbols and current flow and voltage potential/polarity which is unconventional or out of date.

(3) I noticed you already have your domain name "circuit-fantasia.com". Then you can open 100 "accounts" or blogger sites such as "mystories.circuit-fantasia.com". But if are not using their brand name "blogspot.com", they might charge you a fee. Cheers.

TL Fong, I have created 5 empty (for now) "blogs"... I want to create more (e.g., wikibooksstories........) but it does not allow me anymore...

What is not OK with my way of graphical presentation? The only different things are the meaningful letters "D" and "T" that I use to designate diodes and transistors instead the meaningless "Q"...

… My circuit diagrams are conceptual; their role is to show the basic idea behind the circuit... not how to implement a specific solution. Voltage bars and current loops are my specific tools visualizing the invisible electrical quantities voltage and current. Should I explain all this to you? I think I should if you were Olin...

Well, I would suggest you to test the waters by messing around just one blogger site first. Often free site won't let you be overambitious to start with too many things at the beginning. I checked my record and found that I open a couple of sites some time in 2008, and then stopped when I heard Google discontinued there services such as Google+, Google hangout etc.

These couple of years I just wandered in a couple of sites such as All About Circuits, Rpi.org.forum, and only recently Rpi SE, EE SE, Robotics SE etc. It is only a couple of days ago I reopened my google blogger site, but found they changed their user interface a lot, so I need sometime to catch up. I also joined other Chinese forums on and off these years, but too lazy to do maintenance, ...

circuit-fantasia.com is the domain of my site that I create in 2002. I pay $ 50 each year for Seanic's hosting and domain. But I don't see the connection between it and this blog. Do you mean it?

(domain name)

tlfong01

@Circuitfantasist As I said, then you can have something like mystories.circuit-fantasia.com, "negative-resistance.circuit-fantasis.com, etc, if you are still paying USD50 a year.

@Circuitfantasist I understand you saying that "My circuit diagrams are conceptual", but there is big problem, you strange notation are chasing away the readers. Now it is the Tik Tok Generation, nobody would bear with you more than 15 seconds to first listen to you the introduction to your strange notation.

Perhaps you can upload an introduction to your strange notation as a Blogger blog and I will comment there to suggest how to pull you chased away audience back, perhaps using Circuit-Lab schematic drawing, with colour coded arrows, to denote current flow and voltage polarity/drops. Ah, I missed my tea. See you later.

I still can't understand what is my "strange notation". What you are talking about? Voltage bars (the "red lines" as Olin contemptuously said in his only comment below my articles) and current loops? If so, yes... it is strange since it is something original. Every new idea is strange for the conventionally thinking (or simply "non-thinking") people... I do not want to use "arrows"; I want to use exactly bars and loops...

@Circuitfantasist Yes, I agree that you CAN use innovative bars and loops. But I think you SHOULD, at least for now, use traditional representation if you don't wish to chase away your audience. As I said earlier in CD, I have no problem understanding you strange notation, it all boils down to physics, and then mathematics, and then philosophy. I rembember I mention Emma Noether in the beginning of this chat.

I have cut the pictures uploaded here, and I am going to move them to tunnediode.blogspot.com. I suggest we carry on our discussion there.

@Circuitfantasist I have post something to begin our discussion on circuit analysis and synthesis: tunneldiode.blogspot.com/2020/12/emma-nother.html You might also like to post something at you circuit story in you blogger site.

Ah lunch time. See you later.

I am googling more tools to design the tunnel diode oscillator. I have little idea what inductors and resistance to use to oscillate the tunnel diode. I am reading an I2C impedance converter datasheet to get some idea:
https://tunneldiode.blogspot.com/2020/12/ad5933-1-msps-12-bit-impedance-converter.html. I am thinking that the tunnel diode with external inductance is sort of RL impedance. Sot this converter chip might be useful in the oscillator design or measurement. I dont quite understand the DFT operation. So experimenting with the real DSP chip might help understanding better.

I am temporarily stopping because I need to get organized ...

No problem. As I said, take you time. It is a long project. I might take as least two weeks to sort out the PCA8951 ADC DC sweep sig gen, and Rpi CM4 setup. I learnt the tortoise and rabbit race story. My grandmother always tells me "If you want to go too fast, you won't arrive". As I told you, I started my couple of Blogger sites in 2008 .

And on and off, I messed around with perhaps 10 more other blog sites. So you might might need perhaps at least a couple of weeks to catch up. Have a nice weekend. Cheers.

OK, I wrote an introductory post to the blog...
