Wall plotter update #4: pulley size calculations, ready for fabrication

February 13th, 2012 – I’m at the point with my wall plotter project where the virtual and theoretical information has to meet up with physical components and design considerations. In particular, now that I have the required electronics to build a wall plotter, how do we design pulleys and other mechanical components to actually make the plotter a reality? […]

Wall plotter update #3: electronics assembled and tested on breadboard

February 7th, 2012 – Last week, the electronics for my wall plotter were acquired, and are ready to be assembled and tested. This week’s activities were obvious: go for it. This was simple enough that I actually spent a few hours writing up a length, in-depth article about how to assemble and test all the electronics, but then I […]

Wall plotter update #2: electronics acquired, installation space decided and ‘how-to’ in the works

February 4th, 2012 – This week, I received the electronics parts for the wall plotter from Pololu and began writing a complete ‘how-to’ article to help others create their own wall plotter using the approach I’m following. From left to right, the parts are: 1x – micro servo 2x – A4988 stepper motor drivers 2x – stepper motors In […]

Wall plotter update #1: new name, code and parts

January 23rd, 2012 – Renaming the project to “wall plotter” When I first started looking at creating a wall plotter drawing machine, I was strongly influenced by an Instructable’s article from Sandy Noble called Polargraph Drawing Machine wherein he outlines a selection of similar projects and discusses his contributions to the idea. By starting with this project as a […]

Building a polargraph: project motivation and initial thoughts

January 15th, 2012 – As part of an graduate-level independent study course I am taking through my university’s Art department, I will creating a polargraph drawing machine and installing it in a public hallway for public viewing. The polargraph will hopefully be a short but sweet project meant to expose undergraduates, faculty and passer-bys to the artistic applications of […]
