Stuart 514551c9f2 CMMS fork: AI bridge reads the project from IndexedDB, not the globals 
Console showed buildProjectView reporting "4 photos" but NO
buildProjectImages line at all - it was hitting the silent
`!bomImages.length` early return. The studio.js bomData/bomImages
globals get transiently emptied while a project loads / auto-stitches,
and the get-buffer handler's `await` between buildProjectView and
buildProjectImages is enough of a yield to catch that window.

- buildProjectView + buildProjectImages + applyProjectPatch now call
  db.getComponents/getImages/getNets(currentBomId) directly instead of
  reading bomData/bomImages/bomList.
- buildProjectImages traces on entry ("start (board: ...)") and after
  the DB read ("N image record(s)") so an empty result is never silent.

PCB ReTrace

Digitize, document, reverse engineer, and generate schematics for printed circuit boards entirely in your browser.

Launch PCB ReTrace | Examples Gallery

🔍 Overview

PCB ReTrace is a local-first web application designed for electronics engineers, repair technicians, and hardware hackers. It helps you move from a physical PCB to a digital representation using only photographs.

It runs 100% client-side using HTML5, Vanilla JS, and WebAssembly. No data is ever uploaded to a server.

✨ Key Features

  • BOM Management: Map components on board photos to a digital Bill of Materials.
  • Visual Inspection: View multiple board layers (Top/Bottom) simultaneously.
  • Computer Vision Stitching: Automatically align close-up macro shots with wide-angle reference photos using OpenCV.
  • X-Ray View: Manually stitch Top and Bottom images to trace vias and through-holes across layers.
  • Netlist Tracing: Click-to-trace connectivity and export to KiCad compatible netlists (.net) and SPICE netlists (.cir).
  • Schematic Generation (Schema ReTrace): Generate and route schematic diagrams from traced nets.
    • Interactive Editing: Drag components, rotate them, and replace symbols.
    • KiCad Libraries: Import .kicad_sym libraries or ZIP archives to assign standard symbols to components.
    • KiCad Schematic Export: Export a generated schematic diagram to a KiCad compatible format (.kicad_sch).
  • Integrated Tools:
    • Resistor Color Code Decoder (3-6 bands)
    • Inductor Color Code Decoder
    • Air-core Coil Calculator
  • Privacy First: All data is stored in your browser's IndexedDB.

🚀 Getting Started

Online

Simply visit the GitHub Pages deployment.

Offline / Local Development

Since the project uses no build tools, you can run it directly from the source:

  1. Clone this repository: 
    git clone https://github.com/dev-lab/pcb-retrace.git
  2. Navigate to the docs folder (where the source code lives): 
    cd pcb-retrace/docs
  3. Open index.html in your browser.
    • Note: Some features (like Camera access) require a secure context (HTTPS) or localhost. For best results, use a simple local server like Python's http.server.

🔗 Sharing & Deep Links

You can easily share a reverse-engineered device setup by hosting an exported ZIP file on a public server (like GitHub Pages) and creating a deep link.

Append ?import={URL} to the studio address: https://pcb.etaras.com/studio.html?import=https://example.com/my-device.zip

(Note: The hosting server must support CORS by sending the Access-Control-Allow-Origin: * header).

📂 Project Structure

This project follows a "Build-Free" architecture. All source code is located in the /docs folder to support GitHub Pages directly.

  • docs/studio.html: The main application entry point.
  • docs/schema.html: Standalone schematic generation and netlist visualization.
  • docs/guide.html: PCB ReTrace User Guide.
  • docs/resistor.html: Resistor Color Code Decoder.
  • docs/inductor.html: Inductor Color Code Decoder.
  • docs/coil.html: Air-core Coil Calculator.
