Hybrid teaching (face-to-face and distance learning) enables students to better prepare and complete their courses. In science, technology, engineering and mathematics, it is important that practical training be an integral part of the curriculum. Laborem project developed at the technological university institute in Bayonne, France, enables undergraduate students to carry out part of their lab experiments in electronics remotely. Started in 2011, Laborem platform was based on proprietary solutions. Since 2017, the platform has migrated to open source software (PyScada) and open source interface box (Laborem Box), which was developed in order to enable the connection of several circuit boards to be studied. These boards, called plugs, are easily interchangeable and enable teachers to quickly adapt the proposed circuits to their course. The software also provides a simple front panel to adapt the human machine interface that is available for students. Laborem Box consists of a 3D printable box, a power supply board, a set of plugs, and a motherboard that enables students to study the selected plug. In addition, a single board computer is embedded and a hard disk can be used if necessary. This paper is intended to describe the hardware and software design of Laborem platform, and to serve as a guide to explain how to duplicate and deploy this system, primarily dedicated to undergraduate students for learning basic electronics.
