I was watching How To TEST OP AMPS Using A Multimeter vs Op-Amp Tester Project Single Dual and I learned about this Operational Amplifier OP AMP Tester For Single Dual OPAMP TL071 TL072 TL081 TL082 Single/Dual Op Amp Test Board.
I have to cool it on the spending for a little while, but I’ve made a note of this on my shopping list.

In this video I unbox my new UNI-T UTi260B thermal imager with macro lens and compare it with my Noyafa NF-521 thermal imager.
I made a few mistakes with the production of this video, sorry about that. I made a mess of the side branding, I will have that fixed in future. And I managed to get my toes on camera. The height of professionalism!
In this video I refer to my lab equipment documentation. Particularly I mention the Jackcat Mini Cutter electric scissors.
Note: in the video I’m not sure what “ROI” means, but it turns out it means “region of interest”. The region of interest is a box in the middle of the display, and some settings apply to this area.

Let’s go shopping!
I swear, ChatGPT knows everything. Today it told me I could run the following in the developer tools console to speed up YouTube video playback beyond the “maximum” of 2x up to 3x (or more!).

Gonna work through this playlist today: Learn to solder by Branchus Creations.
Found some good videos with various approaches to repairing traces on a printed circuit board:
Found this video about how to desolder: Desoldering Made Easy – Amazing Trick || Soldering Tutorial. He was using 340°C iron temperatures.
Watching Pure Electronics Repair. Learn Methodical Fault Finding Techniques / Methods To Fix Almost Anything I learned that a thyristor—which is also known as a Silicon Controlled Rectifier (SCR)—is a type of TRIAC.
The name “silicon controlled rectifier” is General Electric’s trade name for a type of thyristor.
I have various workspaces in my lab, and I call one of them my “booth”. It’s called the booth because I use it when I need to take photos of things which I’m selling on eBay, usually Xbox consoles or games.
Anyway the booth is also setup with two video cameras, one for a view of the booth bench and the other for a view of my face while I am working in the booth. There’s a retractable drawer bolted under the booth bench too which is full of breadboard jumper wires, so this is the place where I do some of my electronics projects, particularly my Maxitronix X in 1 projects. It’s also a convenient workspace when I’m breadboarding something, as I have ready access to my component drawers above.
Today I’ve installed a number pad in the booth so that I can control my cameras in OBS Studio while I’m working at that bench:
The computer I’m using to do the recording for In The Lab With Jay Jay is called ‘wonder‘ and it only has six USB ports. I currently have ten USB cameras, and I’m getting more, so I don’t have as many USB ports as I can use. Also ‘wonder’ only has 2TB capacity (non-RAID) for storing the videos I record, which will probably get used up fairly quickly.
So I have been planning an upgrade for ‘wonder’ known as ‘victory‘. My new studio workstation ‘victory’ will have 52TB of RAID storage for video data, 2TB of SSD RAID storage for video recording, 12x USB ports on the back panel, and 4x USB ports on the front panel.
Along with this new studio workstation I intend to get a new camera, a Canon Rebel SL3.
Now all I need to do is save up a cool eight grand!
Today while watching EEVblog 1559 – PCB Design: Trace Current Rating I learned about the Saturn PCB Design Toolkit.
