openBrushograph painting tools for brushes, inks & improvised machines.
openBrushograph grows out of the Brushograph experiments in "brushology" – playful ways of painting with a mechatronic brush. It brings together low-cost CNC mechanics, open source software, brush heads, inks and hacked-together controllers. Here you will find firmware extensions, software tools, workshop files and documentation for openBrushograph machines and related experiments.
