Mechanical vibrations appear across a diverse range of applications, but nevertheless are unified by a core set of principles and phenomena. In this article, we describe a reconfigurable laboratory kit that is designed to be used as part of a first undergraduate course in mechanical vibrations. The kit was designed to be low-cost and allow for a series of laboratory experiments to be performed remotely. Using a common set of core hardware and software, five laboratory experiments are detailed and can be performed to supplement many of the major topics traditionally encountered in a first vibrations course. This accessible platform will readily enable further technical improvements and expansions, as well as the development of additional instructional modules.
