poor's man CNC hot wire cutter - Updated!

This time I built a computer controlled device that will allow you to cut out shapes from styrofoam boards with great precision.

The scanners I found them on the trash (officially I will deny that I pick stuff from the trash), the hanger I got it from my cleaning service and the hot wire was 3 euros.
