A while back I caught a Hack a Day¬†post of Sandy Noble’s polargraph¬†project. The artwork he produces with the machine is amazing. I found myself in the workshop a few months ago looking for a new project to work on and realized that I had enough spare parts laying around to take my own stab at creating one of the machines. The concept is pretty simple. A pen is suspended from two spools at the top of the machine and by turning the spools¬†appropriately the pen can be made to travel across a sheet of paper in any pattern you want. All you really need to complete this project is something to mount everything on, a couple of stepper motors, an arduino and motor drivers (I had gecko drivers laying around, but a motor shield will do), and some way to hold the pen. The code that you need for the project can be found on Sandy’s site.

Here’s a couple of videos of my completed machine at work on it’s first real drawing:

And here are a few pictures of the project and some of the completed works.
