Abstract A simple optical-lever amplifier constructed from components normally available in a university physics department is described. The design was based on one by Jones, but was modified so that it could be built by a final-year undergraduate. The amplifier was used to study the Brownian motion of a galvanometer. From this study, the value of Boltzmann's constant [formula omitted] was found to be [formula omitted], the accepted value being [formula omitted].
