Abstract. Despite the critical role electronics plays in instrument design and data collection and processing, the teaching of electronics in analytical chemistry has diminished. More commonly, current instructional methods focus on a systems approach to instrumentation that stresses design layout using preconfigured modular electronic components. This article describes the construction of a low-cost AM radio that places a greater emphasis on the design and construction of electronic circuits. The project uses active learning strategies so that students must problem-solve, think creatively, and learn to work in a team environment as they design electronic circuits to achieve the project goal. The activity serves as a platform for more sophisticated student DIY semester-long projects such as Raman spectrometers, NMR probes, and cyclic voltammeters among many other instruments.
