Remote lab, power supply.
This paper describes an installation of a remote laboratory exercise. The exercise focus on understanding how to set up a normal power supply, and discovering all the obstacles and pitfalls when selecting components and configuring a power supply. Rewiring and troubleshooting of breadboards is time consuming and use cognitive resources the students should use on understanding the aim of the experiment: how power supplies should be set up. The motivation for using remote lab is twofold. Firstly a desire to separate training in using breadboards, and the complex task of understanding the experiment, and secondly widening the time the laboratory experiment is accessible for the students. The components used in the installation are standard equipment, e.g. transformer, breadboard, and low-cost I/O-devices, for fast, easy and affordable assembly. The presented laboratory were set up and tested in the course of one week, and students who were invited to test the system, gave positive feedback.
