OpenWall is an open-source project that has been created through the development of different vertical plotter systems, presented as part of various installations over the past two years. These “vertical plotters” are able to cover large surfaces using a minimal amount of components to present a variety of graphical outputs.


Starting from the experience we gained on previous models, we reflected on what was the best way to create the simplest of devices.


Based on a laser-cut chassis made from mdf or plexiglass, the design of the OpenWall has sought to minimize the number of components needed and simplify as much as possible its assembly and use, making reproduction of the device easy.


The two on-board motors stabilize the plotter and make its installation fast and simple, requiring no external components.


OpenWall uses theProcessing / Arduino platform, making it easy to reprogram to work with a variety of applications.
