Gah!

I am way behind on my videos for In The Lab With Jay Jay, but it’s not for lack of trying! I’ve recorded the video for project 9 of the Maxitronix 20in1 something like five times now, but I still can’t release it because the circuit will not work as advertised. It’s suppose to be a demo of a monostable multivibrator, which is also known as a one-shot multivibrator, but the circuit isn’t working the way that a monostable multivibrator is supposed to work. I’m still in the process of debugging it. I think the problem is a problem with instructions and not my implementation (the instructions are fairly low quality and unreliable in my experience so far), but I haven’t arrived at the bottom of this one yet. I will continue to try and solve this conundrum tomorrow.

Thank God

From CVE-2024-3094 XZ Backdoor: All you need to know:

Fortunately, the malicious code was discovered quickly by the OSS community and managed to infect only two of the most recent versions of the package, 5.6.0 and 5.6.1, which were released within the past month.

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:

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:
