How to draw with electricity. DIY pen.

If you have electronic skills and a good soldering iron, then you can create a pen that draws electric discharge. The layout is quite simple and will require several readily available parts to create. The principle of drawing is based on burning paper placed between two electrodes, one of which is the pen itself, and the second is a copper plate under the sheet.

To get a line, you should not lean the pen close to the surface for a long time, otherwise the paper will burn through.
