    I love to tinker, so this thought came to my mind last weekend
    while I was camping. Why not install an igniter(like a gas grill) in
    my Coleman stove? Since I'm a geek, I don't want to just settle for
    the piezo push-button type. I want the electronic push-button type
    like the more expensive gas grills have. I'm pretty sure they run on
    one or two AAA cells. I'd settle for a 9V if that would make the
    circuit any easier. Could anyone point me in the right direction for
    making such a circuit? I've done some searching on the web, but I'm
    not finding much. Thanks.
     
  2. Go to Big Lots and purchase a plug in air ionizer for a car. This
    device plugs into a cigarette lighter and costs exactly $1.00.
    Carelessly disassemble it and you will find a nice little circuit board
    that generate approximately 1600V dc with a 12V input. You will find a
    gold colored rectangular surface that acts as the ground side and two
    little gold posts spaced about 1/4 inch away from the afore mentioned
    ground plate. Somehow attach a wire to the ground plate or in place of
    it, your choice. Ground this wire to the burner. Connect another
    conductor in place of the gold colored posts and mount it somehow so
    that it is approx. 1/8 inch from the burner. I recommend using
    something that wont burn up when the stove is in use. Now when power is
    applied to the module nice sparks will result. Some experimentation is
    in order of course. The module will withstand at least 15V, maybe you
    can get away with 2 9V batteries in series and not let the smoke out.
    YMMV and good luck.

    I saw one of these when trudging around with the wife and just had to
    see how (actually if) it worked. It's quite impressive for only a buck.
    There is a transistor, a transformer, several diodes and caps (voltage
    multiplier) all mounted on a circuit board with liberal amounts of some
    kind of silicone to prevent arcing. Not bad for a buck. BTW, the stock
    module makes a real pretty purple glow when powered at 15V. ;-)
    Careful, as it will shock the piss out of you, but then you already knew
    that...right?

    you could use a coil from a car and a spark plug. That will surely ignite
    your stove

    Thanks! I think I'll be stopping by Big Lots after work. Now I just have
    to figure out how to mount the second half of the ignitor.

    Yes, I know to be careful. A disassembled camera flash module taught me
    that lesson when I was about 10. :)
