To represent the various topics of our research we defined a hypothetical electronic device, and the workflow will be illustrated by describing and analysing all the steps that is necessary to cover in order to to bring such object from a breadboard overloaded with wires and components to a more stable and reliable prototype. Following a research through design approach, we will provide up date guidelines regarding how to design every aspect of an electronic music interface using exclusively open source software. This article aims to analyse and experiment a variety of open source Computer Aided Design (CAD) applications with the goal of further spread the use of open source CAD software among media artists, designers,and researchers in the field of STEAM (Science, Technology, Engineering, Art, Mathematics) applications. Although these applications have reached a good level of maturity, their use in the artistic field is still not so widespread, due to an initial barrier probably caused by a lack of accessible documentation and best practices. This task could benefit from the high performance tools offered by state of the art Open source Computer Aided Design (CAD). The practice of designing and building instruments, interfaces and hardware in general, became a crucial part of contemporary audio and media arts productions.
