IOIO Plotter

The design is a simple easel-mounted wall-style plotter. A marker is suspended by two strings, each is rolled on spool, which is driven by a stepper motor. The entire setup is controlled by an Android tablet through a IOIO board. The app in this repo (https://github.com/ytai/IOIOPlotter) allows converting photos from the camera or gallery into abstract vector drawings and immediately execute them on the plotter.
