README

README.md

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.

Questions

How big is the Singletramtransv1 PCB?

It measures 56.6 × 57.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Singletramtransv1 use?

25 parts, built around the S9013. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Singletramtransv1 KiCad files?

From the orri93/electronics repository on GitHub, at the commit this page was made from: the board is circuits/singletramtransv1/singletramtransv1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Singletramtransv1 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
