Nextel serial charging for always-on GPS

nextelnextelnextel

Tim uses his Nextel phone as a GPS receiver for his laptop. This drains the battery on the phone much quicker than usual. He decided to jump power into the system so the phone would actually charge when it is plugged in. The power is tapped from the 5 volts coming from the USB to RS-232 adapter. A full schematic and list of phones that this should work on are available at the site.

    “The FBI has shut down the button hack site citing violations of the DMCA and fears that terrorists might use the hacks to “cross the streets of America at will.”

    Oh this is neat!
    Do you know if we can access the GPS on other phones? Namely kyocera or audiovox ones (virginmobile prepaid stuff -_-) it would be neat if I could use the phone as a GPS hehe though that does seem quite complex.

    Awdark, Buy me one and I’ll try. LOL.

    Probably there might be a way it depends how Kyocera or Audiovox programmed it in. Look around in your phone and see if there is an option to turn on NMEA output if there is then you probably can get a cable to send it to your computer, if not then its more complex than that and might require some software to be written.
