Expanding the capabilities of the ELVIS iLab using component switching

Abstract

iLabs are online laboratories that allow users to access, control, and perform real experiments remotely through the Internet. Users are able to access laboratory experiments whenever and wherever they want, bypassing the problem of acquiring expensive equipment and waiting in long queues to use the equipment. iLabs allow students to complement their theoretical calculations and results with real data, providing them with a better understanding of engineering concepts. The ELVIS iLab was developed using the National Instruments Educational Laboratory Virtual Instrumentation Suite, a low cost, all-in-one electronics workstation that can be software controlled. ELVIS iLab is currently in the second version and this thesis explains the modifications made to the first version to add an additional power supply and switching capabilities. These changes increase the quantity, flexibility, and variety of experiments that can be created and provides the possibility of more challenging assignments for students. It also facilitates easier sharing between courses and institutions.
