  • How to Make a Three-Pendulum Rotary Harmonograph - Karl Sims
    A harmonograph is a mechanical device that uses swinging pendulums to draw pictures, believed to be originally invented in 1844 by Scottish mathematician Hugh Blackburn This 3-pendulum rotary type of harmonograph gives a wide variety of pleasant results, and is fairly easy to build once you've settled on a design and have acquired the
  • Harmonograph | UCSC Physics Demonstration Room
    A harmonograph is a simple mechanical machine consisting of multiple pendulums and is used to demonstrate the effects of coupled oscillators by tracing out geometric patterns Our harmonograph consists of two pendulums and traces Lissajous Figures when set in motion
  • Harmonograph - Paul Bourke
    The two pendulum harmonograph draws attractive patterns that arise from drawing the relative path traversed by two swinging masses as their motion is slowly damped The resulting figures are called harmonograms or sometimes a Lissajous curve
  • WorldTree Software - Intro to Harmonographs
