Last month, the team of Red de Acción Comunitaria was invited to San Juan de Pasto, Colombia, to develop the 2nd Design Makerthon, focused on two main components. The first one, directed towards experts in electronics, used the Reacción-Mínimo, a low-cost, programmable and customizable version of the original Reacción Kit (link to reaccion.net) designed specifically to teach participants about the basic protocols of communications needed for communities in case of natural disasters in vulnerable regions. The second component was directed to designers and consisted in the uses of digital fabrication tools in order to analyze environmental variables and to design community-based monitoring solutions in short time. Both teams participated simultaneously in the design process and generated feedback for the creation of more complex solutions.
