• 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.

• 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 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.

• 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.
