We describe the construction of a near-infrared camera for the University of Wyoming's 0.6m telescope at Red Buttes Observatory. BIRCAM (Buttes InfraRed CAMera) was developed as a temporary instrument to test the electronic and cryo-mechanical components of a more ambitious near-infrared imaging spectrograph currently under development. Our goal is to use BIRCAM as a test bed for the design and development of cryogenic opto-mechanics and near-infrared data reduction techniques. BIRCAM makes use of a Hawaii-2 array sensitive from 0.8-2.4 microns. Specific design elements that are shown and discussed include: an Offner relay optical design, stepper motor control of a filter wheel and system integration and communication. One of the science projects envisioned for BIRCAM is a photometric survey of northern Galactic Cepheids. Preliminary results are presented.
