Mechanical plotting device
When I gave a workshop at the School of Art and Design in Offenbach about building digital devices out of cardboard, the students asked me to build a machine as well. I always wanted to own a plotter – so I didn’t have to think too long about what exactly I’d build.
The cardboard plotter is made out of Finnish cardboard, which is very durable, but also easy to cut with a hobby knife. The axles and slide rails are made out of welding rod. Everything is connected with super glue, adhesive tape and tie wraps.
As an interface, I built two rotary dials and a switch. One of the dials moves the pen in y-position. The other dial moves the table under then pen in x-position. The switch lifts the pen or puts it on the paper. When I was done with building the plotter, I also compiled a little code book with coordinates for several drawings. They are written down as a list of numbers from 0 to 9, which makes it effectively a very simple digital storage medium for low resolution vector graphics.
You can find further hires images – also of the building process – in this album.
