An idea to stop bomb blasts

These recent blasts in Delhi have created a storm inside my brain. I’ve been thinking if this can ever be stopped. I believe we can.

Ash thinks we could come up with a electronic jammer that would stop the triggering of the bomb. That’s a fantastic idea.

I’ve another idea. I think if we could develop a tiny device that would detect any explosive material in its circumference. We’d then plant these devices all over the public places. So anyone dumping the bomb, would get caught.

I believe this idea will work. What do you think?

    Great ideas, but I think first we as a country should adopt some really good personal, computer security practices. Like having a password for our Wifi networks. Why should these idiots get access to our Wifi networks to learn how to build these bombs first and then send us emails warning us. Let them use their own networks to do this.

    I have done a post on how we can fight back by setting up a secure Wifi network to start with. We are all as shocked as you are. My sympathies with the families of those suffering.

    Abid,

    You know, its hard to trust people these days. Of course, personal security practices would be great. I’ll go through your post soon.

    Its a good idea but will not work. Most of these bombs were made from ammonium nitrate. Now your device might detect it. But it will not detect ammonia. Its just an example

    moreover where all will you put it? and in what radius can the device detect?

    Are our engineers sleeping? I believe its very much possible to make a device that will detect ammonium nitrate, RDX and whatever that’s regularly used to manufacture bombs.

    These devices can be planted everywhere – at public places.

    Do you know the detergent you use can burn like a fire cracker? What all preventive measures will you take?

    Kill the terrorists in public view. So that no other person even thinks about bombing us, forget daring.

    You can detect inorganic nitrates using existing explosive detection kits. However, they cost around $200 and cover a very small area. We’d need to find a more cost effective way to detect them.

    We could try using laser spectrometry and fit it to cameras. Akin to infrared lens where you only see

    … heat intensity, “Tunable diode laser absorption spectroscopy” can detect the decay products of Ammonium Nitrate. 🙂

    “Tunable diode laser absorption spectroscopy”

    LOL, does it work? If yes then is some one from RAW, Interpol, FBI or whatever except ISI is reading this? Please save our world from bombs or kill those who dare to make one

    @ Mayur
    TDLAS is usually used for gas detection and whatnot. It has only been recently applied for bomb detection. The usual TDLAS equipment set up is quite elaborate, requiring a pressurized gas chamber to feed the sample gas in, and the laser will need to penetrate through the gas. The receiver on the other end will detect the changes of signal intensity.. and you can pretty much measure a variety of parameters. Obviously you can’t lug all the optics and equipment in the field, but there are now handheld portable versions of the TDLAS which is pretty suitable for “field” operations. The US Army Research lab as done reports on it, but the implementation is still preliminary.

    We don’t need to have a fully functional TDLAS, just one that can adequately detect the decay products of the nitrate explosive. We can fabricate our own using the optical components easily available in the telecom industry, and hook it up to the computer. The main analysis (FT, etc) will be performed in the comp. MATLAB should be sufficient. Have a couple of low powered (read: safe for the eyes) lasers pointing all over. Hook up a CCD camera, and overlay the image with the laser data. The result? The operator can “see” which object on the screen has potential explosives in it. You can also make the laser/camera/computer system remote and send data “wirelessly” to the Police HQ. This is MUCH safer than shooting x-rays into the public, haha.

    There are still some issues, such as potential interference and how to efficiently get the lasers to reflect back from the background topography.. but should be an okay challenge for crazy engineers 😉

    Maybe we should shift the discussion back to the forums :p

    hello……..its sagar here from karnataka persuing my b.e degree in mech branch n m in last year now…….i was finding some preventive ideas for d bomb blast for my project as it is a major burdon today….n gone through u r page…its fantastic idea to sence d components of the bomb any how…..sir i hv an another idea..just instead of thinking of sensing d organic components we can defuse it or detect it by thinking about timer which is d common component in most of d bombs used recently…so this is another way i think…..coz those rascals cant plant it without timer…reply

    we can make a active mechanical device which ill b free to move in all directions……we can fit this into buses n
    trains inside at d top……add any explosives or any other components (bomb components)detective device n a laser battery…..(why laser battery?) as soon d kit ill detect d bomb the mechanical link will turn in that
    direction activating d laser battery with a buzzer so than not only the bomb but also d approximate position can b detected where it is planted……its difficuilt but not impossible i think……working on this…..if any related ideas pls reply

    its good idea
    iam searching for same
    the devices that can find these expoled item
    can reduce the rescue factor
    and leave safe life

    Since lead stops futher radiation and emmission of explosive substances,i suggest that the equipments for building the bomb dectator should be made of lead,and public places should be monitor carefully, although lead is aswel harmful to human health.. But the people involve in this have nothing to gain,they do not have common sense…
