Arduino 3D-Scanner

The heart of the system is an Arduino Nano, measuring the distance with an infrared sensor (GP2Y0A41SK).
I read the data over the serial connection in SciLab and transform the polar distance measurements into 3D-coordinates, which are then drawn in the graph.
I drive it by two stepper motors of the type 28BYJ-48.
To provide sufficient power, I followed a nice tutorial to get higher speed and torque:

The used stepper motor drivers are DRV8825 by Pololu.
