The development in numerical technologies modifies and shapes interests of today's students but it also makes possible the emergence of new pedagogical tools as remote laboratories. The instrumentation of technological systems and distant interfaces offers new possibility for a distant learner and it takes more into account the student's interest in internet, web communication and gaming. The remote laboratory platform, designed with this objective, is running and evolving since 2009. In this paper, we present the evolution from a proprietary solution to an open source solution. So, informatics and electronics developments are needed. Based on these objectives, a novel approach using Python as unique programming language is used. A generic PCB (Printed Circuit Board) approach has been designed to answer robustness and adaptive needs. These developments will help to reduce the cost of the remote laboratory and give more flexibility to use it on wide applied sciences practical works.
