As you know the capacitive touch screen, unlike the resistive, needs to feel the electric charge of your finger. While in the resistance, which is formed by a membrane mobile, simply touch the screen with any object, the capacitive screen works only if you feel an electric charge, then the pen must be strictly conductive.
For the realization I used readily available materials. Of course you can wander with the imagination as rigualda the body of the pen, the important thing is that it is metal.
Material:
An old slat curtains. (the one that stretches with two holes at the ends)
A clip of a pen to throw.
A piece of foam anti-static. (This is the gift you can ask a store of electronic materials. In short, is the foam that protects the pins of the ICs from electrostatic charges.
