Greetings:
I want to make a stylus for a capacitive touchscreen which has a rolling ball at the end - like a ballpoint pen. I would like to make it myself in order to get the right size, rather than try and modify existing styluses on the market.
I would really appreciate any pointers as to how to do this. Couple of points to note:
(a) The ball has to stimulate the touchscreen (of course).
(b) The surface of the ball has to grip the touchscreen, otherwise it won't roll.
A solid metal ball won't do because of (b). I tried an old style mouse ball which is fine for (b) but fails (a).
Preferable would be a solution where the ball is able to stimulate the touchscreen by itself, rather than say depending on some kind of conducting link with the case or user's hand.
Thanks in advance for any ideas.
