    Car Alarm + Smoke machine = ?

    Ok so once you've filled your car with lots of expensive equipment you start to worry about car security...
    I had an idea for the ultimate in car security and as with all good ideas - somebody has already done it

    http://www.alansmith.co.uk/alarmselect/vgs.htm

    The car alarm triggers a smoke machine which fills the interior of the car...

    Of course my idea on the cheap was fitting something to the car alarm which goes "If car alarm is off and somebody opens the car door then unleash fire extinguisher canister"...

    Hadn't thought round depressing the whole fire extinguisher thing but imagine your surprise if you're trying to steal the LCD and you get a face full of carbon monoxide gas...

    Cool

    fire extinguishers contain carbon dioxide..

    The problem with using one of these is that the gas comes out rapidly and imediately freezes this can cause harm to a person or to your vehicle potentially. If you can some how limit the discharge you should be alright.

    Carbon dioxide is poisonous in quantity.. if somehow it comes to pass that someone gets stuck in the car and the extinguisher discharges they could suffer great injury, or even death. Then you are accountable.


    I thought of making an alarm with a small compressed air canister with an electronic valve and a relay with the warning "caution, this car is being illegally removed. Cabin environment will be toxic in 30 seconds" at this point the criminal just hears the his of air being released if you set up nozzles or something you might get a misting effect.

    I think the smoke machine is brilliant!!

    I like the smoke screen idea,
    But I wonder if there is a smell or any other side effect to the car.

    That is a good idea. I believe the glycol fog is similar to the stuff used in fog machines for theatre and entertainment purposes. The only difference with those ones though is that they need 120vac, are much larger then that one, and take about 5 minutes to warm up.

    The glycol fog is very harmless though, as long as you arent asthmatic, you can breathe it in, and it wont hurt you.

    LOL,what about a tiny little bit of tear gas? maybe mix it with the regular fog. i dont quite know if it would be legal, but the police use it, so it cant be that bad.

    edit: well tear gas is illegal in canada, except for use by the police/military, so that idea is out, but something along those lines maybe.

    My brother runs a mobile DJ thing and I've seen his smoke machine - actually I took most of the skin off my hand with it at the end of one night. Those things really heat up.... I didn't realise that that was the same stuff that he used...

    I don't how much he paid for it but I know those things can be all hooked up to control software (the lighting systems and things all can be controlled from software - DMX or something it's called I think)...

    So smoke machine + some logic circuit = 325 + 17.5% tax...

    Not likely....

    Btw, if anyone is interested on the whole security front - there is a diy car immobilizer page here :
    http://www.autospeed.com/A_0059/page1.html

    Think it's basically a hidden reed switch and a magnet in your key fob which reconnects your car ignition.

    Obviously if you're car is older (like mine) then you'll worry less about cutting the ignition cable to do something like this...

    Yeah, the DJ type fog machines are the ones ive used. The only problem with them is they take time to warm up, about 5 minutes for new ones, but it gets longer as they get older.

    DMX is the interface, its very complex, its not a simple serial protocol i dont think. Its capable of controling 512 different devices (its used for lights, fog machines, etc) per cable.

    Fog machines run about 700-1000+watts
