Interlude #16: False Start for Learning the Art of Electronics | In The Lab With Jay Jay

Silly Job Title: Lightning Tamer.
This project’s homepage is here: John’s wiki § Learning the Art of Electronics.
This video is me making a false start on the Learning the Art of Electronics series which I am just about to embark on. What happened was after I got a bit more than two hours into recording the video for the first lab exercise I realized that it was taking too long with my approach. I didn’t want to make another twelve hour video! I was planning to go through the literature in painstaking detail and cover everything, but it turned out there was way too much material for that approach to be feasible.
What I am planning to do instead for the actual first video (due out next Tuesday) is do all the reading by myself in advance and then offer a brief summary and some recommended reading. I’m going to try to make the bulk of the video the actual practical experiment/circuit and leave the reading out.
But since I recorded the video for this “false start” I figured there’d be no harm in posting it by itself. Most of this video is the Appendix O material from The Art of Electronics 3ed which is a brief introduction to oscilloscopes.
In this video we mention CMOS technology, particularly MOSFETs.
We mention the Josephson effect which can cause a current to flow across superconductors in the absence of an applied voltage.
The SI size prefixes are documented on my wiki.
In this video we learn about voltage and current.
We take a close look at Appendix O in AoE which introduces the oscilloscope and mentions delay lines.
We mention quantization, Planck units, and Zeno’s paradox.
I show you can illustration from Getting Started in Electronics.
If you’re planning to follow along with the series the pre-reading for the first video coming out on Tuesday is: E&M ch. 1, 2; PoEC ch. 1; AoE app. A, ch. 1; LtAoE ch. 1N, 1L.

Phil’s Lab
Today I discovered Phil’s Lab YouTube channel and Phil’s Lab – Example Hardware Designs. That was after I found him on his instructor page on FEDEVEL: Philip Salmony. Phil’s courses were recommended by @rehsd which is how I learned of him.

In this video we introduce a new feature of the show. In these segments we will be working through Learning the Art of Electronics.
We will be doing a total of 27 videos for this feature. 25 labs, this introduction, and a conclusion. Videos will come out on the first Tuesday of every month (hopefully!).
We did a new book teardown for this book last year: New Book Teardown #3: Learning The Art of Electronics: A Hands-On Lab Course (2016) | In The Lab. You can see in the comments a number of people encouraged me to make videos for this book, so that’s what we’re doing now.
Also a shout out to my mate over on Learning as a hobby for encouraging me to undertake this project.

Homework
This is a part of the homework feature of my blog, which is an ongoing conversation with my mate S.F.
Hey mate. Lovely to see you again, as always.
I have a note here about Milo but I’m not sure why.
There is a rumor that the story of Snow White and the Seven Dwarfs is about cocaine addiction, particularly that the Seven Dwarfs represent the various stages. But Snopes says this theory is bunk.
Two authors Strunk & White wrote a book called The Elements of Style which is a style guide for formal grammar used in American English writing. Famously they said “let every word tell”.
The phone you gave me I named ‘skadi’ after the Norse goddess Skaði.
According to John Cleese in his hilarious letter Something of a Retraction: Cleese letter to the U.S., French fries aren’t French, they’re Belgian.
I heard a rumour that DeepSeek says there are three r’s in “strawberry” but I can’t find a corroborating source.
Penny Arcade is great. I mentioned this one: Dirty One.
In Laws and Sausages the structure of the United States of America is explained in a comic format.
In Death of a Salesman there is a famous quote “A salesman is got to dream. It comes with the territory.”
Tribal not racist.
I think all you need for subjective experience is one or more sensors. Both consciousness and self-awareness are different to that. Although they probably do entail subjective experience too.
I should have a promotions policy on my website. Thanks for the suggestion. I will look into this.
There is a famous RFC: Key words for use in RFCs to Indicate Requirement Levels. This, for instance, defines what the word “should” should mean.
The seven check marks are elements of white privilege, given as:
- male
- white
- heterosexual
- at least one highly educated or wealthy parent
- at least one parent born in the Netherlands
- a VWO diploma (preparatory scientific education)
- and a diploma from the University
In Outliers the author Malcolm Gladwell comes to the conclusion that success is mostly luck. In the same book Gladwell says that to attain mastery the a subject needs to be actively studied for 10,000 hours.
In Magic Words and How to Use Them the author explains how you can use uncompromising positivity to craft the life you want. Seemed to work for me, if you’re positive about people they seem to magically be positive back.
The Old New Thing is a blog from Raymond Chen, a long time programmer from Microsoft who had a lot to do with Windows.
I mentioned that Alan Kay worked for both Atari and Apple.
The famous quote “Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.” is from Andrew S. Tanenbaum.

Why You Will Marry the Wrong Person from Alain de Botton.
Before you speak let your words pass through three gates:
- is it true?
- is it necessary?
- is it kind?
