A new page on Probabilities. Added info on it about how to generate random numbers that follow a specific distribution.

Updated the Resistors page from Markdown to AsciiDoc format.

Added a red horizontal bottom boarder to all h2 headings in the main content of each page.

Added parasitic models of resistors to the Resistors page.

Consolidated all the info on non-isolated switch-mode power supplies (e.g. buck converters, boost converters, buck-boost, SEPIC, Ćuk) into a single page. And then added more info, as well as updating the basic schematics of the various topologies to match this site’s style.

Added info on MQTT clients suitable for embedded devices.

Expanded the TOC to contain heading levels 2 to 4 (beforehand it was only showing level 2).

Added the ability to define multiple authors per page, and added an author block to all content pages. Followed a really useful tutorial at https://moonbooth.com/hugo/authors/.

Added a safe operating area (SOA) graph to the BJT page, and added information on secondary breakdown.

Added info and schematics on adding protection diodes to linear regulators.

Added info on low-dropout linear regulators.

Updated the Ethernet page with info on serial-to-ethernet ICs.

New AWS IoT page.

New Isolated Switch Mode Power Supplies page, with info on flyback converters including basic schematics and feedback using optoisolators.

Added info on how to design foldback current limiting with a linear regulator.

A new page on Gas Discharge Tubes (GDTs), with schematic symbols, designators and examples.

Added a new example of a noisy waveform to the Electrical Noise page.

Added a new page (in notes format) on Spark Gaps.

Added info on transient surge waveform specification, including a graph illustration the concept behind 8/20us and similar specifications:

Moved Zener diode info into it’s own page.

Cleaned up many of the schematic symbols on this site for a consistent look and feel:

Added a diagram showing the protection diodes common to most digital CMOS pins.

Combined the "Passing A C++ Member Function To A C Callback" page into the "C++ Callbacks" page. Updated the page with much more info, including worked examples which use https://replit.com/@gbmhunter for hosting, compiling and running small snippets of C++ code.

Updated the Electrical Noise page with info on the various "Colours of Noise" including graphs (in both the time and frequency domains) of white, pink, red, and blue noise.

Added info on Hakko soldering tweezers to the Soldering Irons And Stations page.

Starting testing the Asciidoc format and comparing it against the Markdown format.

Added schematics, equations, worked examples, and bode plots on Capacitance Multiplier circuits.

Removed the "Test And Measurement" section of the site. Moved the only page underneath it (the "Current Probes" page) to under "Tools" instead.

Added a new page on AC/DC Electronic Loads.

Added a new page on Line Impedance Stabilization Networks (LISNs).

The main structure of this sites HTML was updated to use Bootstrap containers and columns to create a responsive layout. At the same time, the main menu was updated from a hover-based tree view to a expandable tree view which should be more friendly towards users with touch screen devices. The Table of Contents for pages is now also added at a fixed location in a right-hand column for large screen devices.
