In this video I clean my 1% and 2% tolerance resistors (my 5% tolerance resistors were cleaned previously). That’s 37 component trays worth, being 37 different types from 1Ω to 1MΩ. During the video I print new labels for the component drawers with my label maker and I use my iPhone to double check the colour coding.

Unfortunately I missed a little bit of footage near the end of the installation because my camera locked up.

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.

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!

I mentioned Iain McGilchrist, he’s a psychiatrist who dabbles in philosophy. I think he has a really excellent and interesting view of things. It’s hard to summarise his position but he is very interested in the difference in perceptive capabilities of the left and right hemispheres of the brain. He has a YouTube channel over here: @DrIainMcGilchrist and if you search for him you will find many a fascinating interview.
I mentioned Eben Moglen, who has a website over here: moglen.law.columbia.edu. I find Eben inspirational. He’s always talking in grandiose eloquence about the importance of free software, if you search for him on YouTube you are bound to find something of interest.
I have a note here that says “positive view on nihilism” but I forget what that was about. Something I wanted to tell you, now lost to time. But searching for ‘positive view on nihilism’ turns up a bunch of interesting results! (Oh. Wait. Found it! It’s a video I wanted you to see: Optimistic Nihilism.)
Oh, another note I don’t remember: “void of ‘huh'”. I assume we were being hilarious.
There is an urban myth that the first human projectile that made it into space was a manhole cover from nuclear testing facilities for Operation Plumbbob in 1957. I dunno if it’s true, but it’s a good story!
In this video I announce the new Mini Projects. These are a new feature of Silicon Chip magazine sponsored by Jaycar. Each month two or three Mini Projects get published in Silicon Chip, and we will be building those projects together on the channel each month!
If you’re interested in Silicon Chip magazine (it’s really good!) then I would certainly encourage you to subscribe.
In this video I misspoke and said this was the “May 2004” issue of the magazine, but of course it is the “May 2024” issue of the magazine! Unfortunately I missed that errata during editing and didn’t include a title clip correction.
I don’t understand what happened that caused that video corruption we saw earlier in the video. I suspect the workstation I was using to record the video had some other processing task which interfered with its recording speed or something? Hopefully this is not an ongoing problem. It’s not a problem I have seen before.
Update: ElectroneX has now been and gone and my write up about the day is over here: My day at ElectroneX with my friend. I got my photo with Dave Jones!
