    Dear all, i'm a student of final year electronics engineering. we 2 girls are working on our project. first we dint have any idea regarding wat to work on! so finally we thot of having a system to control a car via a mobile phone. the idea behind this is dat a chip will b installed inside da car, with the alarm system of the car and programmed in a way that it will be operated by a mobile phone.
    say the remote control of a car gets stollen, the remote control works upto 1km or so only, but this device can work upto the area the network covers. the chip or sim installed inside the car has a number alloted to it. a command say LOCK send to that number will lock the car no matter where it is, similarly unlock will unlock the car etc.
    this is just an idea! need some help on how to accomplish this. any other idea is greatly welcomed as well!!
    i read a post on communication between cell phone and 8051 i think that can be of some help.

    I seen a project in Elektor electronics magazine ages ago. It was used to toggle a couple of relays i think, which you could use. You put an old mobile phone with pay as go simcard with the circuit (it has to have auto answer). You hack the headset to feed the earpiece into a DTMF decoder and feed the microphone into a speech chip. Then you can call the phone from anywhere.
    Thats all i can remember cos it was ages ago but you might be able to get a back issue.

    Mick.

    You may want to download the Google tool bar...



    Hmm, a Cellular security system, huh? That is actually a pretty good idea... How do you plan on interfacing the phone to the "chip"? Won't special software have to be written for the phone, plus the chip?

    A friend of mine did something similar for his final year project. He connected the system (in your case the car) to an old mobile which he somehow disfigured. When he calls the mobile attached to the system (read car), he amplifies the received signal somehow, does some signal processing and uses the modified signal to activate a relay. I'm afraid that's the much I can provide.

    Really??

    Your spelling doesn't really support you claims. It also makes reading your posts a tedious task.

    In this era of terrorist activity, I would hesitate to get involved in this project.

    Don't you mean "what WE can do"? You stated earlier that you were in a group... didn't you?




    That is a little harsh, don't you think, Russlk?

    Heres the link to the elektor article:

    Remote control by mobile phone


    You have to pay £1.00 to download the article.


    It explains it well enough to understand whats going on. You will maybe have to adapt some parts slightly.

    I'll try and dig out the magazine aswell because i never got around to building it!

    "That is a little harsh, don't you think, Russlk?"

    I think this is a jokster who wants to see how far he can go with this.

    Russlk, you're a little paranoid. Anything can be considered terrorist activity, what makes this so special?

    If someone asking for help getting a 555 timer working, would you help them?

    This is daft. If this was for a bomb detonator, then the maker would simply wire the ringer output to the ignition, not bother with expencive electronics to decode text messages!
