    Yeah, I realised just after I wrote it, that for theft, it's better to miss out the computer bit and just have a standalone unit. I still like the software tracking for fun, though.

    what i would really lik is for my car to send me a text message or something when the alarm goes off....

    i know there are systems available which use a pager etc, but they have limited range (ie you have to be within a certain distance from the car)


    how would i go about doing that?

    I was thinking as I was going to permanently wire an old phone in the car it wouldn't be much trouble to do the following:

    Dial you phone number on the mobile to keep in the car

    Attach two wires to the 'call' keypad connections

    Attach the other ends to a relay, and put the relay in-line on the alarm out

    So in theory when the alarm went off it would dial the last called number (your mobile) , so if your alarm went off your phone would ring.

    It's simple but of course it doesn't require any extra hardware, dunno if it works though

    stevieg,

    Didnt know you have interest in tracking.

    Im too working one out :

    GPS to cell phone output somehow ???

    So far I can transmit the GPS's NMEA $GPRMC sentence through a burst of tone at 300 baudrate using a PIC MCU. The $GPRMC contains the basic info for navigation which is more than enough for locating the car. The PIC is also acting as a phone modem running at 300 buadrate...it is slow but I think its more than enough for tracking.

    Im still in progress of getting the whole thing to work on real phones.


    I think I will be keeping an old phone somewhere hidden to be on the safe side, I might also wire up a relay to the courtesy light of something wired into the call button, so when the car door is opened it will dial my personal mobile - to make sure I know it's gone missing!


    Thats my final goal, the PIC is to send a command to the phone via data cable and text a preprogrammed mobile number when the alarm has gone off or something. To do a live tracking you simply call the number of the tracking phone...this will then continue to send the location to the calling phone thats connected to the PC with a mapping softwares. Of course this tracking phone is hidden somewhere with a backup battery perhaps. It is even possible to control the car PC by texting the phone.

    Anyway until I get a good reliable transmission of the $GPRMC I wont be doing anything more...just a thought anyway

    But in the meantime if you have any more ideas or progress on what you do please let us know.

    TIA

    Yeah, I've been following it since it started, but not knowing much about these PIC modules (apart from following links on the thread!) I thought best leave alone!

    When you've got that working I'll probably make a copy of it, sounds an interesting project and more accurate (and just as reliable) as the cell-phone triangulation. I think a lot of people like us want the tracking but would rather build it ourselves than buy a 800 of the shelf item as long as we can trust it!

    I've also got GPRS working and written an application to upload the location every 20 seconds to a web site. However that's not a real solution as they could just rip out the carpc!!! I'll be releasing the source (web app/carpc app) when I've finished however it does require working GPRS on the CarPC

    Been interesting reading all of the discussions on trackers but they are already available.
    Built-in GSM dual band phone
    400000 position memory
    5 hour transmission battery.
    2 digital inputs (hook up to alarm or entry sensors)
    1 digital output
    GPS port
    serial port to connect to pc.
    You can ring it from a pc with a modem and the supplied software to find the current location, the journey history or to track it in real time.
    Ring it from the programmed mobile to set/reset the movement alarm. If the vehicle moves more than 50 metres it texts an alert to the mobile.
    Pretty much what everyone is looking at already.
    Ok, I'm selling them and they are 300 but it is available and it does work!

    Regards
    Doug

    Doug,

    300 seems like a reasonable price...Im sure the general public would love to get one.

    I dont mind getting one someday but the thing is alot of poeple in here like to make thier own things. For almost all car PC theres always a GPS installed. Almost everyone have a spare mobile phone collecting dust. If the PIC project is to suceed then the whole add on cost for the existing car PC should only be about 10 + the fun of it

    Anyway Ill love to do something with my old pay-as-you-go Nokia 3310 together with the GPS already in the car. All thats missing is the program for the PIC.

    How does the sms payment work with your tracker? is there a montly fee or they work as in pay-as-you-go basis?

    It's like this: http://www.action-replay.co.uk/Mobil...ts/Tracker.htm - it uses a pay as you go SIM card. I think I'm with Ricky327 on this as It's too much for fun making things (and watching it go wrong in the process )

    I'm constantly amazed at the ingenuity of the people here. Sadly I'm bereft of all motor-coordination or programming skills and have to rely on others. (They've even taken cut and paste off my PC in case I hurt myself ) The tracker is a case in point. What we've got works well particularly for the soldering iron phobic amongst us.
    My business philosophy is simple. If I have a need for something then others must have that need as well. If it isn't already being done to death then I'll try and find a solution and bring it to the market. Ok, so it doesn't work all the time (anyone want to buy 2000 hands free kits?) but I'm still in business so I must be doing something right.
    Finding a SIM that allows incoming data calls on PAYG is proving to be a challenge! We're currently using O2 with a minimum charge of 3 per month. Other than that there's no charge.
    BTW If you've already got a Haicom or Fortuna U2 GPS then you can use them with the tracker and save a bit of money.

    Regards and more power to your soldering irons.

    Doug
