Testing the PICkit 5 with the UCMOD-0, moving from Arduino to plain C with MPLAB, and disappearing down a couple of 8-bit microcontroller rabbit holes.

Revisiting two small Go command-line utilities I originally built for my own development workflow: db-concat for assembling parameterised SQL and text files, and repo-status for managing multiple local Git repositories.

How I’ve integrated LLMs into my software development workflow while keeping architecture, code review and engineering responsibility firmly in human hands.

Defining a standard auxiliary connector for UCMOD microcontroller modules, providing additional peripheral interfaces and microcontroller-specific GPIO.

Improving the Protoworks demos and tools, including an in-browser Gerber viewer and an electrical engineering calculation workbench.

Thinking through the next stage of the Protoworks building block board roadmap, including RS485 communications, isolated RS485, digital I/O expansion, low-side driver outputs, 48 V distribution, USB to serial, and future prototype board ideas.

Thinking through how to position Protoworks’ small-batch open hardware building block boards, who they are for, and why open hardware makes sense.

A practical look at using AI as a copy editor to improve clarity, readability, and workflow efficiency—without giving up control or relying on AI to do the thinking.

A practical walkthrough of building a simple compiler for a custom Digital Sequencer DSL, covering lexical analysis, syntax parsing, semantic validation, and bytecode generation for embedded systems.

Defining the core instruction set for a digital sequencer DSL, including SET command behaviour, execution model considerations, and mapping to a compiled bytecode representation.
