In this video I unbox an Ampcom Automatic Network Cable Tester from AliExpress. It was a bit confusing because the AliExpress page says this is an ANENG M469D. But actually it’s not. It’s an Ampcom Automatic Network Cable Tester, which is a similar bit of kit. In the video I test this equipment with both a normal patch cable and a crossover cable and it seems to work okay, so for five bucks I’m a happy customer.

Note: this video is nearly five hours long! If you’re interested but don’t have 5 spare hours (and who does??) you might like to listen at 2x speed or more. The standard YouTube interface only supports playback up to 2x speed but I have some notes about YouTube hacks you can use to set the playback at 3x speed… or more!
Frederick Terman was a Doctor of Science which is what the Sc.D. after his name stands for. It’s like a Ph.D. He is remembered as a father of Silicon Valley.
In the book there is much talk of diodes, but of course that is in reference to the old thermionic diodes which were vacuum tubes. These days diodes are semiconductors made from something like silicon or germanium.
The book talks a lot about power amplifier classes. Today the same classes are still used, it’s just that anything other than class AB and class D are very uncommon.

Then I started having this weird problem where sometimes when I loaded the blog home page I would see binary garbage rendered as text in my browser. I think the problem was either that the Content-Type header was being set incorrectly or that the data was being double gzipped.
I disabled HTTP (gzip) compression and now my page seems to be working correctly again. But I will need to keep an eye on it. If you have a problem accessing my blog, please let me know!
In this video I tell you about the SWAG (Stuff We All Get) I collected this year at ElectroneX.
I had the very good fortune to meet Dave Jones of EEVblog fame. He was nice enough to take a photo and mention my channel on X.
And as if things couldn’t get any better I then went on to meet Nicholas Vinen of Silicon Chip fame. For the record, the very first thing I ever said to Nicholas Vinen was: “is that a spectrum analyzer?” :P
As I suspected J.Burrows is a stationary brand. Must have stolen someone’s pen! Whoops! :P
You can read more about Pogo pins. I’ve never used them myself. Looking at them I’m not sure how you would mount them to a board. Lot’s of things to learn!
You can find more info about the probe tweezers I mention in the video over here: Yum Cha Probe Tweezers.

In this video I fix up one of my Torx T15 drill bits which was damaged by corrosion.
I mention about my broken Logitech C922. I have three of these. They are low resolution (1080p) cameras I use for doing low res video such as with the Welcome Cam, Wide Cam, and Lab Cam. (If you’re interested my good 4K cameras are Logitech BRIO which I use for doing high res video such as with the Bench Cam, Book Cam, and Booth Cam).
The BlueRigger active USB cable I mention is this one: BlueRigger USB 3.0 Extension Cable (32FT, Active, 5 Gbps, in-Wall CL3 Rated, Type A Male to Female Cord). An “active” cable is a powered cable which includes a signal amplifier so the cable can transmit a signal over a long distance, in this case 10 meters (32 feet). I’m not sure if this active cable somehow damaged my Logitech C922? It was working, then it stopped working, but I don’t know why. Maybe dodgy power supply, maybe dodgy cable, maybe dodgy camera, hard to say.
I mention that I’ve been working on the website for the channel. The main website is here: https://www.inthelabwithjayjay.com/ and there is a shortlink redirection service here: https://jjlab.net. You can find all my videos indexed on the site, along with RSS feeds, equipment lists, and other info.
I mention about the upcoming Jaycar / Silicon ChipMini Projects which will be coming up soon. If you’re interested in those don’t forget to subscribe!

And in order to set the <link rel=”canonical”> element I used the Yoast SEO plugin.
At one point I had a problem with garbled content in my browser. Looked like the browser was trying to display compressed content as text. But now I can’t reproduce, so hopefully whatever the issue was it is now fixed…
I added RSS capabilities for InTheLabWithJayJay.com. You can subscribe to the whole thing, or just one channel, or just one show, or just one feature… it was difficulty to create the UI to support that without overcomplicating things. I made the link on the RSS icon support different feed depending on which page you are on.
