I've previously thought about the mechanical device to control her powers, and, while it's a good idea, it isn't fesible for anything but a backup really. But to reiterate, SHE WAS NEVER HELPED OR TAUGHT, how is she to magically learn how to control it, it's like expectinga person who's lived in the wilderness and never had human contact to know how to read or do trigonomitry or something asinine like that. She's only observed that others can control their powers, but she's never been taught HOW!
