Abstract
Maker and DIY projects and resources have exploded in popularity and accessibility. We describe the development of a Langmuir trough system and accessories by undergraduates. LabVIEW provided the base user interface while Arduino micro-controllers were used as the interface electronics. We present a cost effective way to build a modular and disposable Teflon trough. We demonstrate that Arduino and LabVIEW interface effectively. Using a home built 3D computer-controlled router we are able to build barriers and other necessary elements. Additionally, students have designed and assembled several accessories including an automatic cleaning and deposition system. These engineering systems have been incorporated into both curriculum and research in the Biophysics lab at Augsburg College. The development of this system introduces students otherwise pursuing physics and mechanical engineering careers to research questions and challenges at the cutting edge of biophysics and materials science.
