The purpose of cartography is to reveal informations which can not be experienced, either because of a scaling relation, either due to the immateriality of a concept. By being miniaturized, the electronics becomes increasingly inaccessible, leaving the user without the possibility to understand the operation of his device, and highlighting the difficulties related to electronic waste. I choose the mapping as a means of democratization of electronics, trying to simplify the codes of representation for the components. These maps are not only representing circuits, since the use of conductive inks and add of components allows to make working paper electronics devices. Electronic mapping is a research project undertaken over a year, which is at the origin of the following projects: Circuit to link, anatomical board speaker, electronic modules and white paper box.
