Project Title: Polar Drawing Machine
Project Creator: David (https://create.arduino.cc/projecthub/ArduinoFT )
Short description: Most plotters use x and y coordinates, but this one uses polar coordinates. The drawing surface rotates while the pen moves along one axis.
Response: I think this is cool because it is taking a very different approach to something that already exists. Using polar coordinates would probably take up less material and space than using cartesian coordinates because the surface will always be in the same place only needing rotation and the pen only has to move one axis. I would want to maybe demonstrate on a rectangular surface because nobody uses circular paper, even if it may be more space efficient as a circle.
