any ideas for uses for a spare cell phone (Samsung BlackJack)? Answered

i have one lying around and I'm a DIY newbie so I though it might be a cool thing to use for my very first crack at doing something


Open it up to get at the motor, disconnect the motor and replace it with a pair of wires which you feed out of the case.

Set the phone to "vibrate", then whenever you call the phone, you can trigger whatever you have connected the wires to (maybe via a transistor or relay).
