The mobile phone's vibra is an underutilised resource.
By the simple addition of a port on the side of a phone, and a small abrasive cone instead of the eccentric weight, the phone can operate as a pencil sharpener.

It would be a pain to wait around until someone called to sharpen your pencil. |
|
| |
Also, wouldn't the pencil-sharpening noise kind of defeat the purpose of the vibrator? |

No waiting--just call your own number. |

//pain to wait//
Leave the pencil in the phone, and it's always sharp. |

Im not gonna bone this, I think its a cool idea. |

How do you plan to get enough torque from that tiny motor? If you gear it down, you need space for gears not to mention the sharpener and shavings drawer. |

//not to mention the sharpener and shavings drawer//
Well, obviously, the shavings are burned internally, powering a small steam turbine/generator, which tops up the phone's battery.
There is no need for much torque if an abrasive is used instead of a blade. |

If only the shavings could be used to recharge it. |
