The Personal Firewall Vest

[Shadow]

Ok.. sometime by the end of this year I want to create a vest with lots of built in anti-personnel devices (I guess it was kinda inspired when I watched 'The Tuxedo' a few months ago.. hated the movie but the idea stuck).

What I'm thinking of is a dark, loose and baggy jacket. Inside the jacket are

[/b] (For creating a smokescreen, KNO3/Sucrose or mabye a Napthalene mix)

2x Concussion Grenades (For blasting debris/locked-doors etc. Probably MEKP soaked in sawdust or tissue paper or something. Not sure yet)

2x Incendiary Grenades (Thermite filled, with a KMnO4 ignitor)

2x Stun Grenades (For blinding and disoreintating people, see my post in explosives for more)

Small Single-use Flare Gun (If it fits while still remaining concealable)

Remote Detonator (Hidden on the left wrist for grenades)

Low-powered Shock Taser (On the right wrist for close-quarters combat)

Low-range Flamethrower (See pic below)

2x EMP Grenades WOULD be an awesome addition, but I lack the technical expertise to even make a decent non-portable one, so I think I'll just scrap this idea.

The grenades themselves are in small canisters roughly about 10cm in length and 3-4 in diameter. They contain an electric detonator and a rf board for remote detonation via the wrist transmitter.

Now, for the question - If I ripped the rf equipment from about 9 walkie talkies and hooked the speaker wire up to the detonator, would it work?

Example, I take the smoke grenade from my inside left pocket. I flip the 'Arm' switch and throw it about 20 meters away. At the same time I activate the 'on' button on my wrist, and thumb the 'det' switch. It broadcasts the walkie talkie signal which gets picked up by the grenades and current passes through the speaker/det wire.

Now, the main questions.

1) If I get nine walkie talkies of the same brand/make, would they all be on the same frequencies, and if not can I change it so they are?

2) How much of a danger is there about intereference?
Will the general background static of the walkie talkies cause enough current to set off the detonator? (I sure bloody hope not)

3) Can you see any problems in my design so far?


NOTE: I am not a terrorist, but I do enjoy fiddiling with dangerous devices that could be used as such. However, the devices that I use are all designed for entirely non-lethal purposes (I suppose the conc. grenades could be used to kill, but they are not designed to be or I would have includedfragmentation, etc)

Thanks, Shadow

Concussion grenades full of AP would be bad. Suicide bombers use AP in their bombs because it goes off so easy. A better idea would be to make your grenades entirely out of nitrocellulose. make a thick nitrocellulose putty and mold it into a shape, let it dry with a small hole in the center big enough to allow one gram of ddnp. a completely caseless, shrapnelless concussion grenade. I dont know much about frequencies on walki talkies, but i do know that most of them have public channels unless you somehow have your signals encoded so that would be a bad thing, youd hit your switch and then all of them go off at the same time... or someone else uses their walki talkie and you get turned into pink mist.

I have an idea thouhg... why not have a small flame thrower on there too? a wasp spray can full of an alcohol (alcohol would probably melt the plastic hose inside the can and possibly the nozzler too... maybe isopropyl wouldnt... Or possibly grain alcohol) pressurized with butane...

[Shadow]

Ah thanks, that flamethrower idea was brilliant, especially since I already have a low-range and extremely concealable flamethrower just made.

The flame is about that a a deoderant can, but FAR more concealable and lightweight


It uses a similar design to the helltorch found here, but with a built on seperate fuel ignitor.

However, it is not a 'real' flamethrower. It would have some practical uses, but in combat, none. It dosesn't even work on windy days. What you said about the alcohol shot out by pressurized butane intrigued me, but I have little idea how to biuld such a thing

What is a wasp spray can? How do I fill it with alcohol? How do I pressurize it with butane? (etc, etc)

As for the AP issue, yeah, I didn't really want to carry around something so very sensitive (although I was informed suicide bombers typically used a mix of RDX and TNT?) but I don't know how to make any other explosives from the very limited chems and apparatuses I have on hand (I live in Australia btw).

The walkie talkie frequency is a troublesome issue too. Perhaps I can shift the band into a low-used frequency, but when I asked on an electronics site everybody was too scared to contribute and the topic got closed ah well...



EDIT: From now on I will be referring to this as "Project Firestorm (I expect it will take me several months before I get a proper finish jacket am I happy with).
The final product I shall call a Firestorm Defence Jacket (or similar)

1) Yes they will be on the same frequency if it is FRS UHF radios, but i assume you would opt for the cheaper 27Mhz kids walkie talkies from places like Go-Lo for a few bucks.

They will also be the same, however due to the noise ratio i wouldn't trust it to trigger any kind of potentially harmfull explosive.

To do it properly, i would use a Sel-Call equiped UHF FM radio, however this would be out of your price range, especially when it's going to be destroyed.

I just wouldn't trust a walky talky connected to a device, even if it's off when you switch it on you get a mild "spike" which could potentially trigger it.

Is using a striking flint out of the question. Similar to emergency flares. They generally have a few seconds before they fully ignite and react after striking the flint.

If you could do this, a patch of flint on the jacket could be used to strike and start the detonation of the device.

Do it regardless, it would be cool to just light matches off the jacket anyway.

Damn. And yes, those do have practical uses...I know someone who removed a scorpion infestation with one of 'em...

NOTE: The above pic isn't mine, credits go to RatBastard, but I have constructed one quite similar to that.

Anyway, instead of the AP idea I'm toying with the notion of soaking MEKP in sawdust or tissue paper and using that? Should be a hell of a lot more safer.

I've also taken out the idea of a remote detonator. Too dangerous. Instead I will be using timed electronic dets.
