August 2021 Updates

Updates This Month

• 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.

• 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.
