Harmonograph

Harmonograph

Mathematics has always been a riveting subject both conceptually and practically, for the longest time. On my way to practising design, I discovered an outlet into art based off of mathematics. We are going to make a ‘Harmonograph’ based on physical computing using an Arduino.

A “harmonograph” is a drawing machine that makes geometric patterns that are related to the frequencies of activity on (at least) two actuators. These can be made using rotating platters where the relative speed and direction of the multiple rotating platters controls the figure being drawn. Even a simple harmonograph as described can create ellipses, spirals, figure eights and other Lissajous figures.

Proposal: Draw your mood

Imagine we have a twitter mood light, connected to a mechanical arm which draws. I want to make this amalgamation of Arduino projects which detects and ‘senses’ the world mood and represents it via a drawing. After much deliberation and research, I feel that the twitter algorithm has changed(even though I have found a few, wherein this is possible) and it is not possible to tap into its data.

Another possible iteration is to make a device which captures emotions using the press of a button and at the end of the day draws an image based on the prominent emotion of that day. Example: There are a few buttons installed at the PoD, people press(Happiness, Anger,Fear and more), at the end of the day the device captures the most dominant ‘mood’ and draws( I think I have to manually put in the image I want it to draw, though.) a painting relating to the most dominant emotion.

This can also be captured using the Vortolight method which uses a service like IFTTT to reflect colours based on what people tweet about. Essentially instead of changing colour, I would like to ‘move’ the drawing handle in a way which relates to a tweet.

Example: I am angry today #red. This makes the vortolight go red, in the same manner, the robot will draw a little something over a prompt by the tweet.

I looked at a few drawing robots and this seemed the most viable/accurate in terms of using a MECHANIX kit and servos(besides regular electronics) whereas the twitter part is mostly coding and web services(and a wifi module which should not be as expensive, however, the one used in some cases is).

Looking forward to starting with this after your feedback!
