kicad-regrid: Script to quantize a KiCAD eeschema schematic back onto a standard grid
View kicad-regrid.py
#!/usr/bin/env python3
#
# Hacky script to quantize a KiCAD eeschema file back onto a standard grid
#
# Useful if someone somehow moved some components off grid and you want to clean it up.
#
# Usage is kicad-regrid.py <schematic file>
#
# Outputs <schematic file>-regrid.sch. I recommend NOT OPENING the regrid file directly in KiCAD as it assumes a new project
# with that name exists, and you'll probably get a bunch of errors. Just rename it over the original schematic

"Sub-Mate" homebrew Club Mate recipe
View sub_mate.txt
Translated from http://subsalzburg.blogsport.eu/2014/12/16/sub-mate-diy-cooking/
by desperate Club Mate enthusiasts from Australia
Sugar Syrup: 150g sugar, 1 pinch citric acid, 1 half teaspoon tamarind paste.
Mate: 5 full tablespoons Mate, 5x infused so a stronger brew results
Dissolve sugar syrup in Mate brew, add juice of one lemon
You can’t perform that action at this time.
