Once these components were milled, we capped off the oscillating system with the two capacitance sensors and attached the brass mass to the foam with the epoxy-based super glue. Once together, the capacitance sensors can be attached to each end of the housing shown in Fig. \ref{613341}. At the time of writing, this is as far as the project has gotten. The next step is to calibrate the instrument, which I will describe in the section below.
