Started the upgrade from CSS to SCSS (using hugo-extended).

Started migrating from Markdown to AsciiDoc (using AsciiDoctor support provided by Hugo).

Settled on a colour scheme and program (Affinity Designer) for drawing diagrams.

Purchased both Affinity Designer (for making diagrams) and Affinity Photo (for touching up photos), and both have been well worth their one-of purchase price (take that, Adobe and your subscription model).

Upgraded the main menu from hover style interface to an accordion style interface, making it more user friendly for people using touchscreen devices.

Upgraded the base layout of every page to use Bootstrap responsive columns, rather than my own custom CSS to achieve the same level of responsiveness.

Added info about the JST PH/SH W2B connectors used for Adafruit STEMMA/STEMMA QT and SparkFun Qwiic devices.

Added the new page How To Write Super Loops In Firmware.

Added more info about the data types available in C.

Added info on the SOD-923F component package.

Added a new page on the TO-218 component package.

Added more info on the TO-247 component package.

Updated the info on relay flyback diodes, including adding an example schematic.

Added 10-pin ARM SWD programming connector pinouts.

Added more info on the TO-3 component package.

Added info on the TO-39 "Balls Lens" component package.

Added info on the JTAG and SWD programming/debug interfaces.

Added info on RF attenuators, transient limiters and EMC software to the Electrical Compliance page.

Added info on the SWV debug protocol, semihosting and Segger RTT.

Added more variant info and package dimensions for the uSiP component package.

Added info on the SMA RF connector.

Added more info on digital potentiometers (DPOTS).

Migrated the I2C Communication Protocol page from Markdown to AsciiDoc.

Migrated and tidied up the Electrical Suppliers page.

Added equations and plots showing the effect op-amp slew rates have on square and sine waves.

Added info on barrier strips to the Connectors page.

Add info on CAN bit timing.

More info added on the TSSOP component package.

Added info on the PowerPAK SO-8 component package.

Merged the "Logic Gates" and "Metastability" child pages into the parent Digital Logic page.

Added a schematic symbol and internal diagram for the D-type flip-flop.

Added a new page on Visible Light Communication (VLC).

Added info on the XOR gate.

Added info on wettable flanks on the QFN component package.

Added a "How They Work" section to the Analogue Switches page, including a circuit diagram.

Added a new page with info on the SC-89 component package.

Added a model of the input offset voltage for op-amps, a schematic for external input offset voltage trimming, and info on input offset voltage drift with both temperature and time to the Op-Amps page.

Added new page called What Are Transfer Functions, Poles, And Zeroes?.

Add the tutorial: Creating A Scheduled Lambda Function Using AWS CDK.

Added a new page on SMD Crystal Packages.

Added info on the turnover temperature and oscillation mode of 32.768kHz crystals and the negative resistance test.

Added info on RTL and SR latches to the Logic Gates page.

Added info on summing amplifiers to the Op-Amps page.

Added info, schematics and simulation results for op-amp based level-shifters.

Condensed the four battery pages (lead-acid, zinc-air, coin cells, lithium thionyl chloride) into a single Batteries page.

Condensed the diode pages (TVS diodes, LEDs, Zener Diodes, General Purpose Diodes) into a single page.

Added info, schematics and equations for op-amp based ideal diodes and half-wave rectifiers.
