My friend @dcz_ on IRC referred me to this one: Using an Inverting Regulator for Buck/Boost DC-to-DC Voltage Conversion.

Homework
This is a part of the homework feature of my blog, which is an ongoing conversation with my mate S.F.
Hey mate. Lovely to see you again, as always.
I ended up getting these cards printed at clickmedia.com.au to take with me on Wednesday to ElectroneX:
I mentioned Iain McGilchrist, he’s a psychiatrist who dabbles in philosophy. I think he has a really excellent and interesting view of things. It’s hard to summarise his position but he is very interested in the difference in perceptive capabilities of the left and right hemispheres of the brain. He has a YouTube channel over here: @DrIainMcGilchrist and if you search for him you will find many a fascinating interview.
You told me to check out Succession (TV series).
I found the Four Corners video you mentioned, over here: Self-defence or genocide? Asking Israel’s powerful voices about Gaza | Four Corners.
I mentioned Eben Moglen, who has a website over here: moglen.law.columbia.edu. I find Eben inspirational. He’s always talking in grandiose eloquence about the importance of free software, if you search for him on YouTube you are bound to find something of interest.
I mentioned Annie Jacobsen, she’s a pretty interesting cat. She has written a number of books on conspiracy-theory-like topics. I recently read her book Nuclear War: A Scenario.
I have a note here that says “positive view on nihilism” but I forget what that was about. Something I wanted to tell you, now lost to time. But searching for ‘positive view on nihilism’ turns up a bunch of interesting results! (Oh. Wait. Found it! It’s a video I wanted you to see: Optimistic Nihilism.)
Oh, another note I don’t remember: “void of ‘huh'”. I assume we were being hilarious.
There is an urban myth that the first human projectile that made it into space was a manhole cover from nuclear testing facilities for Operation Plumbbob in 1957. I dunno if it’s true, but it’s a good story!
Channel News #3: Announcing Mini Projects | 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 on this show’s homepage which is here.

Silly Job Title: Amp Alchemist
In this video I announce the new Mini Projects. These are a new feature of Silicon Chip magazine sponsored by Jaycar. Each month two or three Mini Projects get published in Silicon Chip, and we will be building those projects together on the channel each month!
If you’re interested in Silicon Chip magazine (it’s really good!) then I would certainly encourage you to subscribe.
In this video I misspoke and said this was the “May 2004” issue of the magazine, but of course it is the “May 2024” issue of the magazine! Unfortunately I missed that errata during editing and didn’t include a title clip correction.
I don’t understand what happened that caused that video corruption we saw earlier in the video. I suspect the workstation I was using to record the video had some other processing task which interfered with its recording speed or something? Hopefully this is not an ongoing problem. It’s not a problem I have seen before.
Update: ElectroneX has now been and gone and my write up about the day is over here: My day at ElectroneX with my friend. I got my photo with Dave Jones!

Corporate Culture in Internet Time
A fun article from back in the before-time just before the dotcom bubble burst: Corporate Culture in Internet Time.
Linux kernel coding style
Today I had a read of the Linux kernel coding style. Eight character indents and brace on new-line for functions and no braces for single line conditionals… yuck. :P
Common files and directories found on popular Linux systems
Over on https://digitalforensics.ch/linux/ there is a PDF you can download which lists common files and directories you might find in popular Linux systems.
New Book Teardown #4: Beginner’s Guide to Reading Schematics 4th Edition (2018) | In The Lab

Silly Job Title: Electron Enchanter
This video is part of the New Book Teardown feature of my video blog.
In this video I take a look at Beginner’s Guide to Reading Schematics, Fourth Edition by Stan Gibilisco published in 2018. The book has 209 pages.
Some things which came up during the video:
From the Wikipedia article on Bifilar coil: A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In electrical engineering, the word bifilar describes wire which is made of two filaments or strands. It is commonly used to denote special types of winding wire for transformers. Wire can be purchased in bifilar form, usually as different colored enameled wire bonded together. For three strands, the term trifilar coil is used.
From the Wikipedia article on Power dividers and directional couplers: Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit. An essential feature of directional couplers is that they only couple power flowing in one direction. Power entering the output port is coupled to the isolated port but not to the coupled port. A directional coupler designed to split power equally between two ports is called a hybrid coupler.
From the Wikipedia article on Waveguide: A waveguide is a structure that guides waves by restricting the transmission of energy to one direction. Common types of waveguides include acoustic waveguides which direct sound, optical waveguides which direct light, and radio-frequency waveguides which direct electromagnetic waves other than light like radio waves.
The list of parts suppliers from the back of the book (some have closed down):
- All-Electronics
- Design Notes
- Electronix Express
- Jemeco Electronics
- Mouser Electronics
- Radio Shack
- Ramsey Electronics
The books from the suggested additional reading:
- Electronics Explained: Fundamentals for Engineers, Technicians, and Makers
- Electricity & Electronics
- Electricity Demystified
- Electronics Demystified
- Ham and Shortwave Radio for the Electronics Hobbyist
- Teach Yourself Electricity and Electronics
- Complete Electronics Self-Teaching Guide with Projects
- Hacking Electronics: Learning Electronics with Arduino and Raspberry Pi
- Circuit Analysis For Dummies
- Practical Electronics for Inventors

Philosophiæ naturalis principia mathematica
Today I discovered Newton’s own annotated copy of his Philosophiæ naturalis principia mathematica.
Altronics catalog
Today my free copy of the Altronics catalog arrived. This is low-tech, but still the best way to keep up to date with the state of the art: just read the catalog from cover to cover!
