Historical Figures from God Created the Integers

I made some notes about God Created the Integers by Stephen Hawking which I have been reading recently. I’m in the process of creating a new book teardown for it. I needed to make some notes about how to pronounce various names. I didn’t do this until I was half-way through the book though. If I had have taken the time to do this activity sooner I would have embarrassed myself less. Anyway. Better late than never!

Subversion @ GitHub

I wanted to use Subversion to checkout one of my GitHub repo branches, because an svn checkout only downloads the files it needs, not a full copy of every file ever added. But I discovered that GitHub sunset Subversion integration earlier this year. Sad face. Still, I suppose the economics justify that decision. As a consequence of my research, which was a bit sketchy because there is still heaps of documentation out there referring to the GitHub features which no longer exist, I did happen to learn about:

Old Book Teardown #9: Basic Electronics – Volumes 1 through 6 (1955) | In The Lab With Jay Jay

In this video I take a good long hard look at the entirety of this book.

The book is Basic Electronics – Volumes 1 through 6 written by Van Valkenburgh, Nooger and Neville, Inc. and published in 1955.

The book is about the state of electronics at the time it was written. It was commissioned by the United States Navy, who used it to train their technicians. Later, it was released for civilian use.

In the book there is lots of material on vacuum tubes, which were state of the art at the time. The sixth volume adds material on transistors and frequency modulation, which were bleeding edge technology at the time.

I learned heaps from reading this book, particularly about the various types of vacuum tubes (also known as “valves” by the British): diode, triode, tetrode, pentode, and Klystron, among others.

Also I learned that the name “transistor” is a contraction of “transfer resistor”, I didn’t know that!

New Book Teardown #5: Electrical Engineering 101 3rd Edition (2011) | In The Lab With Jay Jay

This post is part of my video blog and you can find more information about this video over here.

In this video I take a look at Electrical Engineering 101: Everything You Should Have Learned in School…but Probably Didn’t 3rd Edition written by Darren Ashby and published in 2011.

In the book the author mentioned that they used to write for chipcenter.com which appears to have since been taken over by EE Times. ChatGPT provided more information.

The author also mentioned Mathcad. I’m planning to check that out over here: https://www.mathcad.com/

And some terms which came up (ChatGPT explains further):

Vcc
Voltage at the collector
Vee
Voltage at the emitter
Vdd
Voltage at the drain
Vss
Voltage at the source

Refactoring jjlab.net

I just spent two whole days refactoring and improving my jjlab.net website.

One thing I had to think very carefully about for my modeling was the class/instance distinction for various things, you can see my notes below.

So channels have shows, and shows have features.

A series has segments, and segments have a video.

A series is an instance of a show, and a segment is an instance of a feature.

Everything is easy when you know how!

ISP vs ICSP

ChatGPT 4:

When discussing programming and interfacing with microcontrollers, “ISP” and “ICSP” are two terms that often come up. Here’s a breakdown of what each means and how they compare:

ISP (In-System Programming)

  • Definition: ISP refers to the ability to program a microcontroller while it is placed within the actual system or circuit where it will operate. This method doesn’t require the microcontroller to be removed from its application circuit for programming. It’s a very convenient way to update firmware or make changes to the program running on the microcontroller without needing to disassemble the system.
  • Advantages: It enables easy updates and debugging since the microcontroller does not need to be removed. This can significantly speed up development cycles and make maintenance simpler.
  • Usage: Common in many microcontrollers, including AVR, ARM, and others. It typically requires a few specific pins to be accessible for the programming interface.

ICSP (In-Circuit Serial Programming)

  • Definition: ICSP is a form of ISP specifically using a serial interface to program the microcontrollers while they are installed in a circuit. It’s a subset of ISP with a focus on the serial communication aspect. This method is often associated with Microchip microcontrollers but is not exclusive to them.
  • Advantages: The serial nature of ICSP means it usually requires fewer pins and can sometimes support lower voltage programming, making it suitable for a wide range of devices and situations. It’s particularly useful for devices where space and pin count are at a premium.
  • Usage: Predominantly seen with Microchip’s PIC microcontrollers, though the concept applies broadly. Like ISP, it necessitates access to specific programming pins but often fewer than other methods.

Comparison

  • Scope: ISP is a broader term encompassing any in-system programming technique, including serial, parallel, or any other method. ICSP is specifically about serial programming.
  • Interface and Protocol: ICSP typically involves specific protocols and hardware interfaces tailored for serial communication. In contrast, ISP can use various protocols and interfaces depending on the microcontroller and the system’s requirements.
  • Microcontroller Support: While many microcontroller families support ISP, ICSP is more commonly associated with certain brands or families, like Microchip’s PIC series.

In summary, ICSP is a specific form of ISP. The choice between ISP and ICSP often comes down to the specific requirements of the project, including the microcontroller being used, the available pins for programming, and the preferred programming method. Both aim to provide flexibility and ease of use for developers and engineers when programming microcontrollers within their final application environment.

Old Book Teardown #5: Dictionary of Electronics 2nd Edition (1963) | In The Lab With Jay Jay

Silly Job Title: Spark Slinger

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

In this video I tear down the 2nd Edition of the Dictionary of Electronics by Harley Carter A.M.I.E.E. This book was published in Great Britain in 1963 (following the 1st Edition published in 1960). This book comprises 410 pages of definitions of electronics terms that were current in 1963.
