Note: this video is nearly five hours long! If you’re interested but don’t have 5 spare hours (and who does??) you might like to listen at 2x speed or more. The standard YouTube interface only supports playback up to 2x speed but I have some notes about YouTube hacks you can use to set the playback at 3x speed… or more!

In this video I teardown “Radio Engineering” (3rd edition) by Frederick Terman published 1947.

Frederick Terman was a Doctor of Science which is what the Sc.D. after his name stands for. It’s like a Ph.D. He is remembered as a father of Silicon Valley.

In the book there is much talk of diodes, but of course that is in reference to the old thermionic diodes which were vacuum tubes. These days diodes are semiconductors made from something like silicon or germanium.

The book talks a lot about power amplifier classes. Today the same classes are still used, it’s just that anything other than class AB and class D are very uncommon.

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 ended up getting these cards printed at clickmedia.com.au to take with me on Wednesday to ElectroneX:

John's business card for In The Lab With Jay

I mentioned Iain McGilchrist, he’s a psychiatrist who dabbles in philosophy. I think he has a really excellent and interesting view of things. It’s hard to summarise his position but he is very interested in the difference in perceptive capabilities of the left and right hemispheres of the brain. He has a YouTube channel over here: @DrIainMcGilchrist and if you search for him you will find many a fascinating interview.

You told me to check out Succession (TV series).

I found the Four Corners video you mentioned, over here: Self-defence or genocide? Asking Israel’s powerful voices about Gaza | Four Corners.

I mentioned Eben Moglen, who has a website over here: moglen.law.columbia.edu. I find Eben inspirational. He’s always talking in grandiose eloquence about the importance of free software, if you search for him on YouTube you are bound to find something of interest.

I mentioned Annie Jacobsen, she’s a pretty interesting cat. She has written a number of books on conspiracy-theory-like topics. I recently read her book Nuclear War: A Scenario.

I have a note here that says “positive view on nihilism” but I forget what that was about. Something I wanted to tell you, now lost to time. But searching for ‘positive view on nihilism’ turns up a bunch of interesting results! (Oh. Wait. Found it! It’s a video I wanted you to see: Optimistic Nihilism.)

Oh, another note I don’t remember: “void of ‘huh'”. I assume we were being hilarious.

There is an urban myth that the first human projectile that made it into space was a manhole cover from nuclear testing facilities for Operation Plumbbob in 1957. I dunno if it’s true, but it’s a good story!

I am reading The Brain User’s Handbook: A Neuroscience-inspired Guide to Peace of Mind which has this awesome image I want to share:

Propagation of electricity

Thanks to Craig for referring me to Brian Haidet’s AlphaPhoenix channel.

I found the following four videos on the AlphaPhoenix channel explaining various aspects of the propagation of electricity, which goes some way to explaining how the high impedance headphone might work in my 10in1 2/10 project.

While watching the videos I discovered that Brian’s oscilloscope is a Siglent SDS1104X-E (100 MHz) Oscilloscope, a pretty nice looking bit of kit!

How to Stop Worrying and Learn to Love the Internet

Here’s a fun essay from Douglas Adams: How to Stop Worrying and Learn to Love the Internet. He says that attitudes toward technology go like this:

  1. everything that’s already in the world when you’re born is just normal;
  2. anything that gets invented between then and before you turn thirty is incredibly exciting and creative and with any luck you can make a career out of it;
  3. anything that gets invented after you’re thirty is against the natural order of things and the beginning of the end of civilisation as we know it until it’s been around for about ten years when it gradually turns out to be alright really.
