How to make a Harmonograph - DIY JIG

A harmonograph is a device that uses swinging pendulums to draw pictures. In this video I will show you how to build a special harmonograph called Goold's twin elliptical pendulum. With this harmonograph it is possible to draw images that are impossible with a normal harmonograph.

Many thanks to Prof. Dr. Edmund Weitz for his great support.
If you are interested in mathematics, you should definitely take a look at his YT channel (Deutschsprachig)

The following links lead to Amazon. If you buy something there, I get a small part of the commission, but for you this doesn't change the price. This also applies if you buy something completely different but have accessed Amazon via one of these links. If you would like to support me, just have a look at one of these tools and buy a nice book afterwards.
