Added info on ICs which have different part numbers for different I2C addresses.

Added a /pcb-design/castellation/photo of a castellated daughter board inside a Logitech G810 mechanical keyboard.

Created a new page on current sources and sinks, including a Zener/BJT current source and constant-current diode (JFET current source).

Added JFET schematic symbols. Added JFET info on transconductance and dynamic resistance.

Created a new page on Wheatstone bridges.

Condensed all the temperature sensor sub-pages into the temperature sensor page.

Added a page on termination (electrical termination of transmission lines), including schematic examples of series termination.

Added more info on the SOIC component package, including the SOT-162-1 NXP synonym.

Added info on the SOD-123EP component package, a variant of the SOD-123.

Added info on monitoring loop time to the page on firmware superloops.

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.
