Example output

Everything here was produced by this toolkit and is committed so the README can show real output rather than describe it. Regenerate any of it with the commands below; nothing is hand-edited beyond downscaling for the repository.

Open Air Max (KiCad demo project)

openair-max-*.jpg are derived from the Open Air Max demo project by AirGradient, which ships with KiCad in /usr/share/kicad/demos/openair-max and is licensed CC BY-SA 4.0. These rendered images are adaptations of that work and are therefore also CC BY-SA 4.0 — unlike the rest of this repository, which is Apache-2.0.

File What it is
openair-max-layers.jpg the board contact sheet: 6 composite views, 4 copper layers, 3 renders
openair-max-3d.jpg the isometric 3D render
openair-max-schematic.jpg sheet 1 of 3 of the schematic
# inside the container, because the demos live in the image and /usr/share is read-only
docker run --rm -v "$PWD:/work" -w /work -e PYTHONPATH=/work/src \
  --entrypoint bash eda-toolkit:10.0.4 -c '
    cp -r /usr/share/kicad/demos/openair-max /tmp/proj
    python3 -m eda_toolkit.cli report /tmp/proj -o /work/build/openair-max \
      --dpi 150 --glb --title "Open Air Max (KiCad demo)"'

Revision diff

diff-schematic.jpg and diff-board.jpg are eda diff run over two revisions of the test fixture, with C2 moved on the sheet, R1 moved on the board and its value changed from 10k to 4k7. Red is what the old revision had and the new one does not; green is the other way round, so a part that moved is both. Both are the zoomed detail crop the command writes alongside the full page — on an A4 sheet the change is a few hundred pixels of two megapixels.

File What it is
diff-schematic.jpg C2 red where it was, green where it is now; R1’s value change marked
diff-board.jpg the same R1 move on the front copper
git worktree add /tmp/base <ref>
./bin/eda.sh diff /tmp/base/hardware hardware/ -o build/diff

Both come from this repository’s own fixture, so they are Apache-2.0 like the rest of it.

RC low-pass reference circuit

rc-lowpass-*.jpg come from tests/fixtures/spice/rc_lowpass.cir, which is part of this repository (Apache-2.0). Its corner frequency is 1/(2πRC) = 1000 Hz by construction, which is what the test-suite checks against.
