This section serves as a record of engineering work and technical study across a range of hardware and software disciplines. The material is organized through several categories—projects, embedded applications, laboratory studies, analog and digital electronics, mixed systems, components, and modeling and simulation—each representing a different aspect of practical development activity.
While my primary working repository for notes and research resides in Obsidian, this section presents a curated selection of that work in a more structured and public format. Its purpose is to document technologies, experiments, and design efforts that bear upon ongoing development interests. It therefore functions as a technical record of projects, observations, and analysis related to electronic systems and embedded development. Taken together, the entries form a developing archive of engineering practice—preserving designs, studies, and technical exploration across multiple areas of hardware and software development.
While experimenting with a 128x32 OLED as a voltage meter, it becomes apparent that the display and its associated Arduino SBC provide a pretty good way to set them together on a printed circuit board ...
