In the first video I learned about AppCAD Design Assistant which is a free tool which boasts a broad bunch of features (and, particularly, it can help you design an antenna on your PCB):
S-Parameter Analysis and Plotting
Active Circuit Bias Design
Cascade Noise and IP3 Analysis
Transmission Line Analysis
Signals and Systems
Complex Math Engineering Calculator
I haven’t used AppCAD yet, but I will check it out soon.
There’s a little rebranding in progress. I’m changing my YouTube handle for the main channel from @JohnElliotV to @InTheLabWithJayJay. If you find any dead links please do let me know. <3
Man. I would really like to own a scope which could measure signals at 1GHz or more. Like this RIGOL DS70504 which can do 5GHz. The only problem is the price tag: AU$52,928.99. :(
This video is part of the Old Book feature of my video blog.
In this video we take a quick look at Vest Pocket Guide To Electrical Testing And Troubleshooting by John E. Traister published in 1987 with 130 pages.
In the video I also wish everyone a happy new year, talk a little about upcoming Xin1 projects, and mention how expensive it will be to upgrade my scope to 350 MHz.
And if you’re interested the Wikipedia page for Logic Analyzer says that the first commercially available instrument to be called a “Logic Analyzer” was the HP 5000A Logic Analyzer, introduced in October 1973.

I had a problem where I needed to delete a device driver that had been installed so that I could install a replacement. I found How to Remove Old and Useless Drivers in Windows and the process was roughly:
Win + X: Windows PowerShell (Admin)
SET DEVMGR_SHOW_NONPRESENT_DEVICES=1
Win + X: Device Manager
View -> Show hidden devices
You can then look for the old driver and remove it.
I went hunting in the BIOS for ‘verve‘ which has a ASUS PRIME B550M-A motherboard and I found I needed to change two settings.
The first setting was Advanced -> CPU Configuration -> SVM Mode = Enabled. This enables AMD-V and allows the CPU to function in a hypervisor.
The second setting was Advanced -> Onboard Devices Configuration -> USB power delivery in Soft Off state (SS) = Disabled. This fixes the problem with the power button not working as discussed here: Earth leakage hack.
Man, back on Windows for my new studio computer ‘verve‘. Needed to figure out how to edit C:\Windows\System32\drivers\etc\hosts and that was certainly more difficult than it needed to be.
In the end I used “Method 3” over here to add an “Open in Notepad (Admin)” item to my shell context menu:
