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:

Silly Job Title: Buzz Boss.

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!

This is an old video I found while tidying up my files today. I recorded this back in September 2023, around about a year ago. Figured I might as well publish it on Elliot’s Extras.

In this video I unbox my Yum Cha M6013 Capacitance Meter and my Yum Cha MESR-100 ESR Meter. Then I attach some banana plugs to one of my Yum Cha Probe Tweezers.

Today I was organising my media files and I found this old video. I recorded this back in August 2023 but I never released it. I think back then I didn’t have this second channel and I decided this video wasn’t good enough for the main channel, so it just kind of got forgotten. But I thought it was fun so I have published it here for the record.

In this video I do a time lapse of me cleaning my resistors. While the time lapse is playing I include a narration in which I discuss things I had been reading at the time. There are two links for the show notes, being these:

This is an old video I released on Elliot’s Extras back in September 2023. It didn’t get a write up on the blog at the time, so just doing that now. In this video, which was the first ever video for Elliot’s Extras, my second channel, I organise some of my diodes from AliExpress. This is a really long and really boring video, a perfect fit for the first Elliot’s Extras video. :)
