This is a note for Future John about how to report a recent coredump (with debugging symbols) on Debian:
DEBUGINFOD_URLS="https://debuginfod.debian.net" coredumpctl gdb
Then bt is a magical gdb command to run to give you the call stack of the thread which… failed?

In this video I do the tenth Maxitronix 20in1 Electronic Project Lab project: Speech Conductor.
In this project we learn a little about transistors, amplifiers, and astable multivibrators.
Note: while I was making this video I took a detour into making a cable, which didn’t work out. You can see the video about that over here: Extra Content #13: Failing to Attach Banana Plugs to Microphone Cables | In The Lab With Jay Jay.

In this video I try to attach some banana plugs to my microphone cables, but I do not succeed.
I tried to find some examples of how to do this properly on YouTube, but I didn’t find much: how to assemble banana plugs
I did find a video of a guy who essentially just explained all the problems I ran into: Banana Plugs & Binding Posts
And this one over here confiremed: How to fit a Banana Plug

In this video I take apart a broken kettle then put it back together, then magically it is fixed!
In this video I use my Yum Cha Mini Magnetic Precision Screwdriver Set for the first time. It takes me a little while to figure out how to clip the tips in. I needed the triangle bit for this job.

I have been on the lookout for some good protoboard for a while now, and today I found this: ElectroCookie Solderable Breadboard PCB Board for Electronics Projects Compatible for DIY Arduino Soldering Projects, Gold-Plated (9 Pack + 3 Mini, Multicolor Pack).
It is cheap and well laid out, which is a combination of properties I have had some trouble finding. For instance if you search for ‘protoboard’ over on AliExpress you don’t get any good results.
Anyway. I got myself two twelve packs. Average cost of AU$2.25 per board.
p.s. I went back and got these as well:
This ElectroCookie stuff is good value!

In this video I take a look at Electrical Engineering 101: Everything You Should Have Learned in School…but Probably Didn’t 3rd Edition written by Darren Ashby and published in 2011.
In the book the author mentioned that they used to write for chipcenter.com which appears to have since been taken over by EE Times. ChatGPT provided more information.
The author also mentioned Mathcad. I’m planning to check that out over here: https://www.mathcad.com/
And some terms which came up (ChatGPT explains further):
