does anyone know how an 'active' stylus works? I know it involves magnets somehow-
I bought a hybrid tablet, and playing games on a touch screen is COOL. However, i want to make an ergonomic stylus; my hand cramps up too badly when i play for long periods. I had an idea to buy a wacom stylus and modifying it, and I'm trying to figure out more about how it works before I start. (lol) making stuff is cool; but i would prefer to not go into it blind.
