This video is part of the New Book Teardown feature of my video blog.

In this video I take a look at Learning the Art of Electronics: A Hands-On Lab Course by Thomas C. Hayes and Paul Horowitz published in 2016. The book has 1,140 pages and is a companion to The Art of Electronics 3rd Edition.

Some notes about things of interest we noticed in the book:

Xilinx was an American technology and semiconductor company, now owned by AMD
the Ebers–Moll model is useful for modelling Bipolar junction transistors
Hysteresis is the dependence of the state of a system on its history
Wien’s bridge is used for precision measurement of capacitance in terms of resistance and frequency
Wilson current mirror is a three-terminal circuit that accepts an input current at the input terminal and provides a “mirrored” current source or sink output at the output terminal
a Bessel filter is a type of analog linear filter named in reference to Friedrich Bessel who developed the mathematical theory
the video about the 6502 I watched recently is: The 6502 CPU Powered a Whole Generation!
the Cypress PSoC is a family of microcontroller integrated circuits by Cypress Semiconductor

In this video I create some cables so I can attach my circuits to my roof aerial. I also announce the old book and new book for the upcoming teardowns which will be released in the next few days.

While doing this video I learned over on the EEVblog Electronics Community Forum that the specific RF cable connectors we are using in this project are Belling-Lee connectors.

There is going to be a break in Maxitronix 20in1 videos for a few days while I wait for my new Logitech BRIO webcam to arrive. Once that is here recording in the booth will resume.

In this video I mention the Silicon Chip magazine and Beginner’s Guide to Reading Schematics. Also the various new book teardowns I refer to are:

I also refer to MPLAB X IDE and MPLAB PICkit 4 In-Circuit Debugger.

The technology I mention in the beginning of the video is this:

The new monitor I refer to in the video is this UPERFECT 4K Monitor 15.6″ Portable Gaming Monitor UHD PC Screen USB C Monitor.

The cables I use in this project are these:
