I just wanted this on record to show how insanely good ChatGPT4 is:
I am way behind on my videos for In The Lab With Jay Jay, but it’s not for lack of trying! I’ve recorded the video for project 9 of the Maxitronix 20in1 something like five times now, but I still can’t release it because the circuit will not work as advertised. It’s suppose to be a demo of a monostable multivibrator, which is also known as a one-shot multivibrator, but the circuit isn’t working the way that a monostable multivibrator is supposed to work. I’m still in the process of debugging it. I think the problem is a problem with instructions and not my implementation (the instructions are fairly low quality and unreliable in my experience so far), but I haven’t arrived at the bottom of this one yet. I will continue to try and solve this conundrum tomorrow.
Well, shit kinda got out of hand, and now I have three 4k monitors on my desk.
I didn’t intend for this to happen. What happened was I thought that one of the monitors that I use for my computers on the bench and in the booth was broken. So I hastily ordered a replacement. Then it turned out that that monitor wasn’t broken — the power cord had fallen out — but by the time I had discovered that eBay was telling me it was too late to cancel my order.
So for a lousy AU$250 I now have a third monitor attached to my primary workstation. Since I have pretty much no need or use for a third monitor what I have done is create a desktop background image for it with a bunch of reference material.

In this video I do the eighth Maxitronix 20in1 Electronic Project Lab project: Shot In The Dark II.
This article will tell you all about anodes and cathodes of capacitors: 19.3: Electrochemical Cells
The Veritasium video about the number 37 which I mention is this one: Why is this number everywhere?
This is great: The 6502 Instruction Set Database. It’s a database with details of opcodes for the 6502 processor. You can see the SQL and TSV.
I have this wonderful old book The SCSI Bus and IDE Interface: Protocols, Applications and Programming (2nd Edition). It was published in 1997 but is still available for purchase through Amazon.
The book comes with a floppy disk (that’s right: a floppy disk!). I had to buy a USB floppy disk drive to read it. I have made the content from the disk available in a tarball, here: scsi.tgz.
If you just want to read the files, those are here:

Silly Job Title: Master Planner
This video is part of the New Book Teardown feature of my video blog.
In this video I take a look at Learning the Art of Electronics: A Hands-On Lab Course by Thomas C. Hayes and Paul Horowitz published in 2016. The book has 1,140 pages and is a companion to The Art of Electronics 3rd Edition.
Some notes about things of interest we noticed in the book:
Today I stumbled upon some vintage Dave Jones which made me happy: EEVblog #63 – Microchip PIC vs Atmel AVR. :)
I am reading Make: AVR Programming: Learning to Write Software for Hardware and I found this excellent video: Programming AVR Microcontrollers in C – O’Reilly Webcast available from here: Beyond the Arduino: Programming AVR Microcontrollers in C.
The author’s github page is still operational: https://github.com/hexagon5un/AVR-Programming
Their website littlehacks.org is offline but still available via archive.org: https://web.archive.org/web/20160307235812/http://littlehacks.org/
Also there’s this really cool collection of projects over here: Cornell University ECE 4760 Designing with Microcontrollers Final Projects.
