This video is part of the Old Book feature of my video blog.
In this video we take a quick look at Vest Pocket Guide To Electrical Testing And Troubleshooting by John E. Traister published in 1987 with 130 pages.
In the video I also wish everyone a happy new year, talk a little about upcoming Xin1 projects, and mention how expensive it will be to upgrade my scope to 350 MHz.
And if you’re interested the Wikipedia page for Logic Analyzer says that the first commercially available instrument to be called a “Logic Analyzer” was the HP 5000A Logic Analyzer, introduced in October 1973.

Today is just a quick video to demo my new camera setup made possible by my new studio workstation ‘verve‘.
In the video I demo the new mat/bench camera which supports various zoom levels. Then I demo the iPod touch camera for showing some of the bench equipment. Then I demo the HDMI system which supports two microscopes, the MSO5074 oscilloscope, and the AV switch which usually would show the Xbox among other things (but I couldn’t get the Xbox to work in this video, drats). Finally I demo the thermal cam.
Sorry for the dodgy audio in this video. I will try to make sure that doesn’t happen in future videos.

Today we teardown a homemade continuity tester which I put together for use before I had a multimeter, so that was in the early days of my new lab, circa August 2021.
While I was preparing the links for this blog post I discovered that the plastic case I used for the continuity tester was the HB5610 Black Hand-held Electronic Enclosure from Jaycar. I purchased one of these for AU$9.95 back in August 2021, which was around the time that I made this continuity tester.
I subsequently purchased a ten pack of similar plastic cases from AliExpress for AU$64.55 (inc shipping) in March 2022. I went to find the AliExpress listing so I could link you to it, but it’s an old listing and has been taken down. I did search for an equivalent product but didn’t find what I was looking for. The dimensions are roughly 70mm x 135mm x 24mm and there is a facility for 2x AA batteries built in.
What I say in the video about active vs passive piezoelectric buzzers is correct. The active buzzer will do the buzzing for you, all you need to do is supply some power. The passive buzzer will need an input signal in addition to power, so some sort of oscillator if you want to generate a tone.
I knocked up a schematic for this continuity tester, something like this:
I’m gonna try getting some PCBs made for this circuit from PCBWay, because I’m still trying to learn everything I can about that process!
