In this video I take a look at God Created the Integers edited by Stephen Hawking and published in 2005.

Hawking’s other book which I mention in this video is On The Shoulders Of Giants.

I am sorry that my pronunciation of European names is kind of terrible. While working through the book I made some notes on my wiki about pronouncing various names: God Created the Integers.

At 12 hours (the YouTube maximum video length) this is my longest video so far! If you do watch the whole thing through to the end, you are my type of person, so please do let me know! :)

Silly Job Title: Switch Sleuth

Happy New Year!

In this video, my first video for 2025, I construct a 4-digit digital clock I recently purchased from AliExpress: TJ-56-428 4-Digit Digital DIY Clock Kits with Acrylic Shell, DIY Alarm Clock Soldering Practice Kit for Learning Electronics.

I thought it might be nice to kick off the new year with an actual electronics project, as that is what this channel is supposed to be mostly about!

I translated the instructions from Chinese to English, and those are here: TJ-56-428. These include instructions for use of the complete and fully assembled clock.

This was a great chance to try out my new METCAL PS-900 Soldering Station and I am pleased to report that I am very happy with my new soldering iron! It is a pleasure to use.

The heart of this circuit is the STC15W404AS which is a microcontroller! It has been pre-programmed with the clock functionality, there was no software or source code that shipped with the kit.

Update: my mate @sadata777 pointed out that there was a protective coating on the acrylic and I remove that in this video: https://youtu.be/y9btakLOCHc

Update: my mate Joe pointed out that I had the case on back-to-front which you can see me fix here: https://youtu.be/IyJ3IHgRfiw

Magnetism Detector | Project 12/20 | Maxitronix 20in1 | Learning Electronics In The Lab With Jay Jay

This post is part of my video blog and you can find more information about this video over here.

You can support this channel on Patreon: patreon.com/JohnElliotV

In this video I do the 12th project from the Maxitronix 20in1 (the Sensor Robot 20): Magnetism Detector.

In this project we control a BJT transistor with a magnetic reed switch.

We use the thermal camera to observe heat in the transistors and LEDs during operation.

This is a plain DC circuit with no signals so there was no call for measuring anything with the oscilloscope.

I got myself a little confused about normally open and normally closed circuits during the video, but I think I was clear enough about that in the end.

In this video I unbox my new Kingston FURY Beast White 128GB (4x32GB) 5600MT/s CL40 DDR5 XMP DIMM | Overclocking | Plug N Play | Intel XMP 3.0 | Kit of 4 | KF556C40BWK4-128.

This is the replacement RAM I ordered after the Corsair RAM debacle (wherein they sold me scrap metal, not RAM, really, you wouldn’t dream of it!)

You can read about Kingston FURY Beast DDR5 Memory and find the KF556C40BWK4-128 specs (PDF). There is also warranty information and memory installation instructions.

You can learn more about memory timings, particularly CAS Latency.

Today I managed to double the RAM in ‘charisma‘ from 64GB to 128GB and also double the RAM in ‘treat‘ from 16GB to 32GB. A productive day!

Unboxing #18: CORSAIR HS55 Surround Sound Gaming USB Headset w/ Microphone | In The Lab With Jay Jay

This post is part of my video blog and you can find more information about this video over here.

You can support this channel on Patreon: patreon.com/JohnElliotV

In this video I unbox and install my new CORSAIR HS55 Surround Sound Gaming USB Headset with Microphone made by CORSAIR and sold by Amazon.

If you’re interested in buying a headset yourself you might like to know that CORSAIR has other models. I am very happy with my new HS55 headphones. They sound great and they feel great too.

In the video I install the iCUE software from CORSAIR and the NVIDIA App from NVIDIA.

The NVIDIA App is used to install the drivers for my RTX 4060 graphics card in my gaming rig ‘treat‘. NVIDIA maintains a list of games supported by the NVIDIA App.

We also install the NVIDIA Broadcast software following this setup guide.

I had some trouble I think with the compatibility of the NVIDIA Broadcast software and the iCUE software. If I had my time again I wouldn’t have bothered with the NVIDIA Broadcast software, I don’t intend to use its features (it can filter out background noise on your microphone, but I don’t care about that). The only reason I installed the NVIDIA Broadcast software at all is that the iCUE software seemed to suggest that it integrated with it, but if it does it didn’t work for me. After I reinstalled the iCUE software it seemed to work properly again, so not really sure what happened there, but I think it all worked out in the end. Also I seemed to have some trouble when using VNC to connect to my gaming rig that didn’t happen when I used it directly (via the ATEN CS1922 2-Port DisplayPort KVM on my desk).

There were some YouTube videos from CORSAIR which played during the iCUE installation:

While reading about the NVIDIA driver options I learned about WHQL Testing:

The Windows Hardware Certification program (formerly Windows Hardware Quality Labs Testing, WHQL Testing, or Windows Logo Testing) is Microsoft’s testing process which involves running a series of tests on third-party device drivers, and then submitting the log files from these tests to Microsoft for review. The procedure may also include Microsoft running their own tests on a wide range of equipment, such as different hardware and different Microsoft Windows editions.

There is some more info from Microsoft about the program over here: WHQL test signature program.
