    Trip might be on to something.

    However, why not use a fusion brain?

    Agreed - Trip makes sense.

    The Audrino has a bigger market.
    And it's cheaper.
    (And security is not an issue - ie, OpenSource.)


    PS - I was also thinking degree of difficulty - ie, PIC vs uPC - which Trip confirmed below (2nd reply down).

    My question was since the BT printer is powered on, would it be possible for a passing thug to pick up the BT device (printer) on his phone, gamble with a few passcodes and open the doors of my very locked and very secure truck?

    Going one step further, I also saw these door poppers for door-handle-less entry...

    I dont think security would be an issue because on every Bluetooth device I have ever used you have to make it visible the first time you connect.

    Fusion brain in conjunction with the bluetooth? very difficult. Also the fusion brain requires a PC to do the logic bits. With the audrino you can program it with logic and it consumes very little power. However, it's a bit of a challenge getting bluetooth working with it and that's beyond my skill set (I'm a software hacker, not a hardware guy).

    If you are talking about using the fusion brain/audrino to start the car, that's a different story... I use my scantool and nobdy to start my car remotely over the CAN bus on my car. My original plan was to use this low powered computer + fusion brain connected to relays connected to my remote keyfob. I found the CAN bus method to be much simpler :P.

    I thought I would post the details of this project just in case any one is interested.

    Build a Keyless Unlocker
    Time: 2 Hours
    Cost: $65.02
    Difficulty:Relatively Easy
    1. Open the printer. Slide the battery cover plate off and remove the battery. Snap the plastic bezel off the front of the printer, and remove the two screws that hold the cover plate in place. Remove the narrow ribbon cable.
    2. Route two wires into the printer via the paper exit slot. Solder one to the “TP14” solder connection point on the circuit board, and the other to any ground point on the board.
    3. Reassemble the printer. Slide the two wires through the paper exit slot. Solder the other ends of those two wires to each one of the coil prongs on the relay. Solder two different wires to the remaining switch prongs of the relay.
    4. Open the key fob and locate the button that unlocks the doors. Solder one relay wire to each pole of the switch. Reassemble the fob. Connect the printer’s power supply to an inverter, and plug it into your lighter.
    5. Turn on the printer. Enter passcode 6000 to pair your phone with the printer. Send a photo via Bluetooth, and the relay will trigger the key fob to unlock your car’s doors.

    i believe that justchat's point was that the send-a-picture-from-your-phone-to-a-wireless-printer-to-trigger-a-remote-to-open-the-doors is a lot like a rube goldberg device-- ie: a highly complicated way of doing very simple tasks--the specific image he posted deals with getting toohpaste onto the toothbrush...

    i solve the problem with by using a coat hanger, calling someone with a spare set of keys, or calling the police.. none of these are usually as fast, but they are much cheaper..

    Yes, Justchat is paraphrasing what has been said before.

    But it is even more basic than that.

    Forget using the printer - don't you think there is something else wrong?

    I am certain it comes from an April edition of something else was published on an Australian Forum.

    The Aussies used to power things like solar powered torches (without batteries or caps) and cig plug dc-dc converters for charging your OWN flattery when caught outback (ie - no other batteries or vehicles around), but people got the joke. (That was before it became the "clever country".)
    Mind you, many did try soaking a certain Electronics Australia (April 197x) page trying to activate it's in-printed circuitry.
