    joc_06,

    That link is wicked, the guy is even using the same phone as my test phone. Just read quickly through it...cant wait to see the details about the SMS tracking on 3310.

    Manymanymany thanks for the link

    Ricky - no probs at all - i just read a thread there where u said u were making a shutdown controller pic based. Im interested in this and i was wondering did u ever host the details? Call it a trade??

    No I didnt get around to do it...kinda lost interest really.

    I have finished the circuit diagram as well as the PCB design for it...I have also built it.

    The code seems to be working well but it still need some cleaning up and and need more comments.

    I can still carry on with it as soon as I have more time.

    LOL...I only write in ASM cause I hate C or BASIC.


    Ill start digging up and send you what I have. In fact it was harder to code it than the tracker im doing right now.

    By next week Ill mail it...just a bit busy these days.

    Infact I do have the diagram as well as the PCB in PDF formats.

    Ignore the version number

    I may still to adjust some components value here and there. As I said I havent really fully tested it so there maybe some bugs.

    The source code I can post it next time...but I still wanna clean it up before doing so. Its not exactly easy to understand a poorly commented ASM code. Im probably the only person who can undertstand my own code...since its been while I may have forgoten it...but Ill check it.


    Well hope that helps anyway.


    EDIT :

    Opps I did change the BC547 to a BD139 or something the base resistor is also lowered. Cant remember the exact mods, but this just allow it to drive a relay with lower coil resistance.

    [QUOTE=gadget]I did a few s and didn't find any solution yet, but here is one project I have been thinking about and need help with:

    Vehicle tracking:

    Circuit cellar had a good article on doing this as a standalone system, tracking via gps over cell phone.

    Wireless Vehicle Tracking Part 1 - Feb 2004
    http://www.circuitcellar.com/magazine/163toc.htm

    Wireless Vehicle Tracking Part 2 - Mar 2004
    http://www.circuitcellar.com/magazine/164toc.htm

    Programmed in Forth, my favorite! Find the souce code here.
    http://www.dtweed.com/circuitcellar/caj00163.htm

    Its actually a very well thought out solution I've seen and it handles most of the problems that the solutions posted here don't even address.

    For example, you are nowhere near a PC, how do you decode the data coming in at your ear? Drive home and jump on your PC? Oh forgot, someone stole your car. All you have is a cellphone. Bu the time you get to a PC, several hours could have passed and your car is in Mexico.

    This guy uses voice to read out the gps data, you can call up at any time and find out where your car is. Also, this guy was tracking rental power generators, whenever it was moving when it wasn't supposed to be, it called up a number and started telling you the location, heading and speed.

    Seems like an interesting concept but I cant see the diagram unless I pay.


    This guy uses voice to read out the gps data, you can call up at any time and find out where your car is

    Does it say the name of the road where the tracker is? or does it just say the location in longitude/latitude as ripped from the GPS data? because its pointless if it cant say the exact location in roads or area atleast. Theres probably not much difference in texting the location in long/lat except for the delayed transmision when texting...what can one do if he was given a location in long/lat? its almost meaningless unless theres a software that show exactly where it is on the map...again a PC is needed or a reference map.

    For example, you are nowhere near a PC, how do you decode the data coming in at your ear?

    But a stream of GPS data is only used for live tracking. Its like what do you do with a long/lat being said to you over the phone once every seconds?

    What I had in mind is where the tracking device have a built in map in a CF card. A 128Mb is enough to hold the UK map including all sort of POIs...striping the POIs should bring it down to less than 100Mb or so. I dont know how the data is stored and can be abit too much for the PIC to process all that...thats a bit tricky to implement but it is possible.

    Thanks for the link PHC, but if you have something more in details please let us know

    Well, I re-read the article and the basic principle is you get real-time Lat & Long with heading and speed via voice so you can write it down and you give that to the police, look it up on a map or call a friend who has a computer if you don't have one yourself. It is better than texting in that you can call into the system whenever you want and via your touchtones, change system settings and such.

    Thumbs up Yiou Guys are trying too hard

    This technology exists I have a Benefon made in Finland and it has all the features you require,, external power,,, external ariel (so you can hide it and most important of all you can pole it (send a request for data and it will send back position, speed & direction... this isn't an advert you have to find someone that sells these they are a bit old early 2000 - 2003 (old for cell phones) but wicked tough and smart.... they were originally designed for rescue workers so they do the stuff.....
    Good luck
