In this work we present the experience of the course "Build your own supercomputer with Raspberry Pi", offered as a non-mandatory workshop with the purpose of bringing High Performance Computing (HPC) closer to bachelor students of Universitat Jaume I (UJI, Spain). The intention of the course is twofold; on the one hand, we target towards increasing the knowledge of Computer Science and Engineering students about the labor performed by the HPC community; on the other hand, we aim to create a personalized experience for each student by fulfilling their curiosity about the topics presented and discussed in the class. In order to evaluate the impact and learning, we analyze two surveys filled out by the students respectively before and after the course, where HPC interest and knowledge are exposed.
