Vibe-coded PCB Camera Lucida utility for PCB tracing. It is available from the http://www.marian-scientific.org/ homepage. It automatically requests the webcam feed and allows the user to upload their mask for tracing. It includes all the basic image transforms at the bottom of the page. It seems to work well. Note that the camera needs to face directly down onto the trace plane, and the user will need to ensure the overlay is scaled properly before starting to trace (maybe put the corner points down and ensure those are spaced appropriately). For the sample trace shown below on graph paper, some of the ink bled between the fine-spaced pads, even with an Ultra Fine Point Sharpie. However, this ink bleeding doesn't happen on a copper surface.
