Cell Phone External Timer

  1. Feb 26, 2008 #1
    I am doing a project for school and I am urgently trying to figure this stuff out:

    1. A way to turn off then power on my cell phone every 24 hours with some type of external timer.

    2. I would also like to implement if at all possible some type of external on/off switch besides the traditional key on the keypad. So if I place the phone in a box I can run wires to the outside of the box so I can turn the phone off and on without having to open the box.

    The phone needs to be plugged into a powersource constantly. The mini USB port is being used for the wall charger so I'm guessing it needs to take place where the battery contacts the board. I included a diagram for my idea, and a picture of the phones circuit board and circled where the battery contact was removed. I also included a link to a 24 hour circuit timer I was looking at using. I'm sort of a newbie at this stuff and was wondering if I'm heading in the right direction. Any input, advice, or suggestions from you experienced guys would help alot. Thanks.
