In this video we take a look at my new Peak Electronic Design Atlas LCR45 LCR Meter.

If you’re interested I have other equipment from Peak Electronic Design.

Over on the EEVblog forum I ask What’s special about the frequency 14.9254 kHz? The answer seems to be that this is 1/67th of 1 MHz, which is probably as precise as the microcontroller they’re using can go.

You can learn more about my ALKOY Capacitor Discharge Pen.

There are accessories available for the LCR45. Stuff I am planning to get includes:

I would get the LX30 – Extension Cable for LCR40/45 but it doesn’t appear to be in stock.

There are cases available but I am not planning to get any of those:

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

I mostly published this ten hour long video just to exasperate Dave Jones. ;)

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!

If you would like to watch this video but don’t have ten hours to spare, you can find out how to increase the playback speed more than 2x on my YouTube hacks page.

The links to archive.org I mention in the video are these:

Also I found PDFs for Volumes 1 through 5 here:
