Video: 2D Window Drawing Machine


Alexander Weber has created this drawing machine for his office in Hamburg, Germany. The machine paints his entire window from a pattern read from an SVG file. Weber programmed the device himself, and you can read more at his build blog.
I used Processing for implementing the host software. Processing was the first choice because it is primarily targeted for graphics programming and plays well with Arduino. Any other software that could talk to the serial port would work here as well.

The host software falls into two parts. The first part is for reading an SVG file and sending it to the machine. It starts with loading the first SVG file from a directory if there is one. Then you could still scale, mirror and move the shape on your canvas. If everything fits, the drawing is sent to the Kritzler, one instruction after another.
