A while back, we saw [Euphy]‘s polar pen plotter project. The mechanics of the build are very simple – just a pair of motors attached to a pen by a beaded cord. Even though the build is very simple, it’s possible to create awesome works of art albeit very slowly.
Since we featured [Euphy]‘s polar pen plotter, a lot of improvements have been made. Now the Polargraph has an SD card slot for computer-less printing, a touch screen for manual control of the plotter, and a few new drawing styles that improve on the previous version a lot.
Right now the improved version of the Polargraph is set up in the front of a graffiti art supply shop in Edinburgh where it spends its time slowly drawing a window dressing. [Euphy] put up a few videos of what the Polargraph is capable of doing, very impressive and we hope he gets a few more PCBs in soon.
