In this short article, we propose a simple, low cost and a novel optical method of calibrating DC motors and voltage sources by producing Lissajous-like Spirograph patterns. Merits and limitations of the method are discussed. This experiment can be introduced to a 10+ course or to an undergraduate course with a modest budget.
