The Little Green Box of BOOM!





Introduction: The Little Green Box of BOOM!

A Detonator / Rocket launcher project I did a lil bit ago, I did not document it well building it, But thought id share some photos of it.

(a lil more info)
it works with eather Nichrome Wire (The smaller the Gauge the better, u can get it on E-bay) or The model rocket ignitors u can buy from your local hobby shop, I think I will put up an ignitor Instructable at some point.

(im thinking of makeing a few of these to sell if anyone would be interested? cost would probly be in the hundred somethings [for parts, time and labor] )

    there Stereo jacks so in music terms there is a left ear channel and a right ear channel.

    The basic setup is wire one channel directly to your power Source we will say to the Negative.

    Then wire the second channel from the Positive terminal to a Momentary On Switch Then to the Second Channel on the jack.

    Now when you push the button it completes the circuit (if you alligator clips are ether touching or clamped onto a rocket ignitor or NiCrome wire at the end of your lead wire's that is)

    Fairly quick and simple and works well!

    can you please add a schematic of the electronic circuit, I am thinking of doing something similar and this would be very helpful
    thank you

    it`s been some time and also some time sins u posted this, i don`t think i have the schematic anymore sorry :o/

    it`s just a thin peace of plywood i sanded and painted, using one inch wide masking tape to space the lines and mask the yellow, (use white paint as a base coat then fallow with the yellow to make the yellow pop better, then fallow with your black) uncle keeps his netbook in an ammo can...

    Hmmm I built something similar to this recently for a rocket launch pad, only difference is that I used a larger ammo box and put 4 gel cell 12v volts in(2 pair running parallel). All I have to say is don't try going through an airport with one of these TSA gets pissed, even when you have a paper from NAR explaining that it is completely legal and safe.

    you might not have as much of a problem if they weren't gel cells because for all they know it could be napalm or some other form of explosive.

    Tell em To be precise it is a composition of styrene, benzene, and gasoline although the Geneva convention has deemed that it is not environmentally friendly.

    Based on your description, and some of the captions, I'm guessing you would use this for model rocket ignitors, etc? Either way, it looks really cool. It gives me an idea for putting a computer inside an ammo can. Could be great for LAN parties... Good job. Thanks for sharing the pics!

    it will work with rocket ignitors but u can also use Nichrome wire to make your own ignitors,9volts will make it glow cherry red. and the comp in an ammo box is an awesome idea I have seen it done it makes it nice an portable!

    I wouldn't take that computer into an airport or government facility though, you would probably be tackled by MPs and taken into custody!!! ;-)

    I haven't messed with model rockets for a long time, but this would definitely be cooler than the normal switch contraption that Estes kits used to come with. Not to mention the "Oohs" and "Ahhhs" you could get if you used THIS to light off your DIY fireworks show instead of a zippo/propane torch/punk stick/etc. Classy!

    i will try to bring a detonators in an airport when i am gonna go back to saudi arabia, let's see all THOSE ooh's and aah's xD
