As I said, I have been browsing a couple of forums to compare and contrast their management and award schemes. I am on the CD's mailing list on meta things: In case you have not read already, this CD　article is worth reading: "Codidact's New No Badge System" meta.codidact.com/articles/278234

I found that I have forgotten many basic semiconductor physics and technology terms when I studies the subject. So I think I am not yet "able" (in CD's terminology), or have the prerequisite knowledge to understand the discussions there, not to mention asking question. So I will stall the Q&A part, and go back to do my real word experiments. This reminds that in our deleted CD discussion, I mention the MIT's way is learning by doing, and Edision's quote on failures.

BTW I am showing my way of reading, learning, thinking, experimenting in my blog tunneldiode.blogspot.com, to show the newbies how I am learning to be a hobbyist engineer.

Hi TL Fong! I comp

Heavy snow is falling here. I'm in the car looking at what you've written.

I completely share your opinion on the negative votes. I even thought to warn readers to interpret them in the opposite sense - the more they are, the higher reputation I have ...

I would like to ask you about the blog as another tool for saying what you know... As far as I can see, it's like a diary that shows your thoughts chronologically ...

... and your development and progress ...

I like this because I like to illustrate circuit ideas through my thinking as a concrete example ... I do it by "building" and "reinventing" scenarios...
