Introduction: Arduino Mini Pen Plotter

I am now explore the possibility of my Lazer cutter.

From now, 100mW lazer can be used to cut paper, vinyl adhesive sheets...

but I found that the same structure can also be used as pen plotter.

Just take off the lazer diode and insert a pen.

Remark :

In this video, the outcome is not very good because I did not screw the pen tightly. (It is made of plastic and I don't want to broken it)
