I was watching Computers running very slow, long boot time, unresponsive in windows. Let’s fix it. and Richard said that if your CMOS battery reads less than 3V then you should replace it.

JST PHD Connector Crimping
I found a good video that shows how to crimp a JST PHD connector: JST Connector Crimping. When crimping these JST connectors I use my ENGINEER PA-09 crimping tool. I use a 1.4mm crimp for the wire and a 1.9mm crimp for the insulation.

In this video I recap an old OGXbox. I also redo the thermal paste. I use my Pro’sKit SS-331 desoldering pump in anger for the first time. I spend an inordinate amount of time trying to figure out my new tools. In the end the Xbox is still broken!
I sold this Xbox on eBay but it was returned to me during the warranty period (one month) as it was faulty.
In this video I mention a trick you can do in your browser when you’re watching videos on YouTube. Ordinarily the YouTube user interface only allows you to set playback speed to 2x, but if you want to set it at 3x or higher you can do so by pressing F12 to bring up developer tools, then open the Console, and enter this code:
document.querySelector("video").playbackRate = 3.0;
Change the number to change the playback speed.
In this video I mention that it was in a video from Bruce from Branchus Creations that I got the recommendation to try a beveled soldering iron tip. Having given it a bit of a go and not really having great luck with it I am going back to a small chisel bit instead.
I comment in the video about how you don’t need to replace the clock capacitor on a v1.6 board, but Harcroft on the ConsoleMods.org original-xbox Discord forum reminded me that sometimes you do need to replace this capacitor.
The capacitors I use for this recapping are Chong 6.3V 3300μF Low ESR caps. Of course the board didn’t work after recapping so it’s possible these are dodgy caps.
I’m pretty sure I did damage the tip on my desoldering pump by putting the temperature all the way up to 480°C. Maybe don’t do that yourself. I believe anything over 380°C can damage iron tips (basically they melt!).

Op amp tester
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.
Unboxing #3: Unboxing of UNI-T UTi260B Thermal Imager with Macro Lens | In The Lab With Jay Jay

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.

Speeding up YouTube video playback
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!).

Repairing broken traces on a PCB
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.
Thyristor (Silicon Controlled Rectifier)
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.
