Hardware R&D × AI Automation × Independent Product Experiments
This is my personal engineering lab: a record of projects I have built, tools you can use, and the choices and validation behind each solution.
Turning lessons from RF circuits and system architecture into reusable engineering methods.
02Connecting data, workflows, and agents to reduce repetitive work and validate ideas faster.
03Building usable prototypes from real needs, then improving them through hands-on feedback.
Compares RefDes coordinates in old and new OrCAD HTML reports to find moved, added, and removed test points, with Target List filtering and a DXF board-outline overlay.
Best for：Hardware and test engineers who need to verify PCB test points across revisions.
All user files are parsed in the browser and are not uploaded to a server.
Compares test-point coordinates in old and new OrCAD reports during a hardware revision and labels them Unchanged, Moved, Added, or Removed. Supports a DXF board-outline overlay, allowlist filtering, and mil↔mm coordinate alignment. All processing stays in the browser so CAD data is not uploaded.
Outcome：Combined old-versus-new test-point differences, target-list filtering, and a board-outline overlay in one browser tool.
Notes are being prepared.

I am turning this site into a personal engineering lab and refining how I publish completed engineering projects, PCB tools, and original notes.
I welcome conversations about hardware R&D, test workflows, AI automation, and engineering tools—as well as tool feedback and collaboration ideas.
