[sdiy] [OT?] Schematic capture from hand-drawn circuit diagrams

[Kylee Kennedy]

I looked into this last year. The best you can do is import the schematic
to a CAD app and trace over it. The main issue is even though we can see
the symbols for passives and parts and interpret it correctly with our
eyes. Not all schematics use the same style/size/shape symbols. So you’ll
need machine learning on top of OCR. I think this would be an awesome
thesis project or something for the more computer vision savvy on here.

Want I want is a app that you can use your camera phone pointed at a
schematic and it will create augmented reality and show the signal flow and
voltage directions, etc.

Instead we get stupid AR face jewelry and morphs. lame
