free plans: how to make a|
||A harmonograph is a pendulum-based drawing board that produces beautiful curvaceous drawings.
After you give the large hanging platform a gentle push,
gravity works its magic while a pen records the results.
Each swing is almost identical to its predecessor: the minute discrepancies
are responsible for the remarkably sinuous curves.
The version that we have detailed in the plan below allows you to make drawings on paper or on
an erasable whiteboard. You can set up the harmonograph in a garage or basement
it out of the way when not in use; it ends up taking virtually no space at all. We love to
enjoy the mesmerizing action, but it makes a great conservation piece at a party and kids absolutely
love it! It takes some patience to get everything working right, but it is definitely worth
the fine tuning that this project requires; as always,
we will walk you through all of the steps.
