Scientific paper

A digitally synthesized classroom variable star has been constructed for lecture demonstrations to illustrate three types of variable stars, with real-life light curves for RR Lyrae, eclipsing binary, and multiperiodic stars. The artificial star has been used both as a classroom demonstration as well as in the laboratory, and students gain some experience in data acquisition. A simple classroom photometer is also described, with a large digital readout for classroom use. The data for the light curves is stored in an EPROM memory chip and may be changed to suit the instructor's preferences.
