I use a flat bed scanner - with a black cloth over the top to keep out
the light. By playing with the grey scale values you can usually
separate the tracks from the rest. The component side can be flipped
and overlaid. Beauty of the scanner is the size can be actual and
repeatable.

I've previously tried that but I could not get separation as not enough
contrast between laquer covered tracks and polyester.

Right. If it's any help I use an Epson GT 9500 in 24 bbs colour. Can't
really help with the software as it's RISC OS.

To e-mail, change noise into sound.

Is there a general guidance for human only layout to schematic conversion
anywhere out there? I tend to start with DC rails but then what. I imagine
the numbering sequence for Rs and Cs should give a broad area of where to
plonk them in the final schematic but a thin infinitely extendable rubber
matrix would be nice.

The other problems with using a scanner are possible scratching the document
glass and the solder points end up white rather than black.
