Abstract
We describe an undergraduate project to build a Duffing oscillator. Although the ultimate goal was to demonstrate chaos, the overriding consideration was cost, as this was during COVID-19, and budgets were frozen. Previous designs used expensive parts that were out of the question in terms of cost. An inexpensive design whose centerpiece is a video tracking system is presented, along with some comments about aspects of the theory concerning the bi-stable case.
