Scripts to convert KiCad files for JLCPCB assembly service
View convert_bom.py
# This converts a BOM file in CSV format, produced by KiCad Pcbnew,
# by selecting File / Fabrication Outputs / BOM File
# into the format expected by the JLCPCB manufacture service.
# At least in KiCad 5.1.4 the CSV output seems a bit broken in terms of column names,
# which is reflected in this code. If it changes in later KiCad versions, this script
# needs to change, too.
# Use this by running the command line: python convert_bom.py inputfile.csv outputfile.csv
# It will overwrite your output file without asking so be careful.

"""Make a sliced histogram plot in the style of Joy Division's album cover.
- `data`, a 1D numpy array containing values.
- `ax`, the matplotlib Axes to draw onto.
- `N`, the number of histogram slices.
- `resolution`, the number of bins. Defaults to `N`.
- `white`, boolean. Sets black-on-white colour scheme instead default.
