electronics

A personal collection of electronics projects, experiments, and reusable design assets.

This repository includes circuit designs (mostly KiCad), component libraries, simulation files, prototypes, firmware/code, and supporting documentation. It is organized as a working archive where each project can include one or more of the following:

• Hardware design files (schematics and PCB layouts)
• Build/manufacturing outputs (for example gerbers)
• Notes, references, and datasheets
• Source code or firmware when the project includes programmable parts

Folder Structure

Top-level folders are grouped by purpose. Common locations include:

• circuits/: Main project folders for KiCad designs (schematics/PCBs).
• doc/: Documentation, references, datasheets, books, project notes, and how-to material.
• src/: Source code and firmware-related project code when applicable.
• 3d/: 3D models (for example STEP files) used for PCB/mechanical integration.
• symbols/: KiCad symbol libraries.
• footprints/: KiCad footprint libraries.
• gerber/: Generated manufacturing outputs for selected projects.
• spices/: SPICE/LTspice simulation files.
• prototype/: Early-stage prototypes and exploratory files.
• projects/: Additional project work that may not fit the main circuits/ layout.
• media/: Images and other media assets.
• pcb/: Standalone PCB-related utilities or adapter boards.
• tools/: Tooling and utility resources.
• repares/: Repair-related project material.
• tmp/: Temporary files.

Project Organization Notes

Project contents are not always in a single folder. Depending on the project stage and history:

• KiCad circuit files are often located under circuits/<project-name>/.
• Documentation can be stored separately under doc/.
• Code or firmware is sometimes placed under src/.

This split keeps hardware design, documentation, and software concerns organized while still allowing each project to evolve over time.
