Saw this on a Facebook group I'm in. Been wondering more about different alarms that can get ghetto rigged. Anyone have any thoughts on homemade alarms, possibly silent?

>>11232 on a side note,
you can make a shot gun booby trap that works on similar principals. you need to make a tube for the gasses to expand or else you wont have any power at all pic related. i figure even if you just wrap it with enough duct tape youll be able to get it to do what yo uwant but a 3 inch tube would probably be better

making a rattle can

A glowstick isn't much of a warning, I'd prefer a flare or railway detonator, something that'd wake me the fuck up and make a prowler shit their pants.

Agreed, the kind of trap in OPs post would be better suited for a road flare. Anyone attempted this?

The glow stick would be a good early warning system while people are on watch, maybe about 20 yards away. A area lights up whoever is awake on watch would be alerted.

It wont do much if youre alone or sleeping, you need like an air horn.

Its a tricky situation. You either have something so loud everyone hears it, or something that only you and you party notices.

Zombie/Raider wise, any loud noise will probably alert anything within a mile. Which you don't want to do. Maybe make some snares around the area. Not only do you get them tied up but you can have it so some cans jiggle when he pulls to free himself, its not super loud but enough that being 20yards out you'd hear it.

In the movie red dawn Patrick Swayze says only to shoot once when their party is hunting, if you shoot more than once someone can find the direction the shot came from. Any merit?

It's like using sonar. Every shot is another chance to locate.

Yeah, in an open area the shot will echo, but if you don't kill him in that fist hit, he will sure as hell scream. You also have to take in effect who he is with. IF you hit one and the other starts shooting off, or runs away.

Maybe a can full of marbles would work that seems like it would be loud enough to wake you. Maybe if the trip wire has them set to drop from trees. That alone would scare anyone to move back thinking something is going to drop on them.

Rig some stakes round the perimeter. Wind tripwire through and place bells on the ends near your house so only you hear them. You could rig certain bells up to certain sections of the perimeter for locating.

I have seen small motion detectors selling in packs of 4 or 5 for very little money
Would probably not be hard to replace the speaker with a 433mhz transmitter

And then you got yourself a wireless motion detecting alarm for less then 5$
(You need a com radio to hear it of course)

Why don't you just get good doors utilizing octolocks (The rounds ones) and bars on the bulletproof windows. This way you wouldn't need to know if there's anyone trying to break in because it's not going to happen unless they start blowing your house/bunker up. At which point you were fucked either way unless you're willing to personally defend your property.

THis.

Or, if you really want something electronic, silent and less reliable, you could buy an arduino/Rpi and a bunch of wire. Experiment with different trip mechanisms. Have wire leading your arduino, where an LED array can indicate which alarm was tripped.

I don't get superbunker types. They always have a glaring weakness in their need for fresh air which can have the simplest poison gas pumped in and suddenly your super safe bunker is a gas tank.

I mean unless you have this elaborate pumping system but the vents for that will be found unless it's compressed air replacing the poisoned filtered stuff and it will run out eventually.

I hate bunkers due to how vulnerable they are to basic siege tactics.

That's why the most important part of bunker construction is hiding your air in take/out take

Use a dead tree or big pile of rocks

Are you kidding me? I can take the time to crack it open once its insides no longer might come outside to kill me. Before I do anything trying to open it is like opening Pandora's box. After, it's just opening a really difficult to open box potentially filled with treasure and supplies.

Infrared vision can spot a hidden air intake if you don't do it well enough. A mysteriously warm tree is going to be obvious.

Do you even solar charger? It can be something you take your time with, as you're trying to outlast the bunker people anyway. You just position a sniper somewhere secluded guarding the bunker entrance (or two, three etc depending on the amount of entrances the bunker has) so the people don't come out once someone does and gets shot, they can't see whose shooting but they can't risk looking but think okay maybe they'll go away after some time so we can just hang out. But no, We're looking for air vents.

Again this is why I hate bunkers. The best defense is always a good offense. Having a bunker as a temporary base is one thing but I am not into the whole hoarder thing. Base of operations should be mobile or temporary.

Well the first mistake you did is assume that you know about your enemies plans and set up.
Have fun getting killed by the satellite spider hole sentry guards.
Have fun with the booby trapped air vents.
Oh, and the decoy ones too.

Cause my real one is ground mass cooled, not unlike a root celler.
I really don't think you understand proper bunker construction.

Yeah, things are really easy and simple when you dumb them down to the negative tenth degree...


Keep on straw manning, I'm sure you are just as good as you say you are and you are completely justified in underestimating everyone else.
Good job, keep it up.


Just will make the poor people defending their bunker have an easier time eliminating the threat of a piece of shit attacking their hidey-hole.



Poison gas attack?
Are you fucking kidding me?
Do you think this is some video game? Even if you are making a simple chlorine gas, that is a FUCK LOAD of wasted supplies just for a bunker that you don't know whats inside.

"Oh yeah you know, ill just take this bunker ain't no thing"
Stick to your action movies. The only thing that destroys a near perfect bunker is the people inside or a SCUD missile.

I guess now you're gonna say you got a JDAM.

Man you're so delusional. It doesn't waste tons of supplies to make a gas grenade. Plus I don't even need to use gas, just set everything around the vent on fire and suddenly you have smoke being funneled into your bunker instead of air.

>Well the first mistake you did is assume that you know about your enemies plans and set up.

I didn't assume I knew anything about their plans or setup. Just that if it's a sealed bunker it's gotta have at least one entrance/exit and probably an air vent or two somewhere and yeah, probably plenty of booby traps.

>Have fun getting killed by the satellite spider hole sentry guards.

lol you mean other potential entry points into the bunker? If I come across a bunker I'm going to watch it from far away, scan the area with an IR spotter and map the thing out. Then I'm going to set the forest on fire. When everything's burned down you've either evacuated or you're still in there but now everything's obvious.

>Have fun with the booby trapped air vents.

Dude I'm locating them with IR vision not by rummaging around in the leaves with my flesh puppet hands. If I see one I'm just going to assume there's some kind of trickery surrounding it and start burning stuff.

>I don't doubt they'll be booby trapped,
>Oh, and the decoy ones too.

Why would I even notice decoy vents? The real ones will be working and emitting a heat signature.

>Cause my real one is ground mass cooled, not unlike a root celler.
>I really don't think you understand proper bunker construction.

Carbon dioxide from breathing emits a heat signature and you need fresh air in a bunker. And I doubt you won't be running machinery with some sort of emissions.

>Yeah, things are really easy and simple when you dumb them down to the negative tenth degree...

You sound mad.

>Keep on straw manning, I'm sure you are just as good as you say you are and you are completely justified in underestimating everyone else.
Good job, keep it up.

Really mad.

>Just will make the poor people defending their bunker have an easier time eliminating the threat of a piece of shit attacking their hidey-hole.

Butthurt even. Did my casual talk of touching your hiney-hole upset you?

>Poison gas attack?

Yes.

>Are you fucking kidding me?

No.

>Do you think this is some video game? Even if you are making a simple chlorine gas, that is a FUCK LOAD of wasted supplies just for a bunker that you don't know whats inside.

Dude smoke from burnt debris pumped into an enclosed space is toxic. Making poisonous gas is as easy and as resource consuming as making a fart.

>"Oh yeah you know, ill just take this bunker ain't no thing"

It's not that difficult.

>Stick to your action movies. The only thing that destroys a near perfect bunker is the people inside or a SCUD missile.

lol this is the kind of uncreative linear thinking that separates the dead from the survivors. This wouldn't be some RTS videogame where certain constructs have specific weaknesses and strengths.

>I guess now you're gonna say you got a JDAM.

Nope and I don't need a fancy bunker busting missile, that will destroy the hordes of food and ammo inside. What a waste.

Uses fire on a structure designed to with stand fire.
Doesn't understand basic bunker construction and how satelite bunkers work. They are not connected to the bunker dipshit.

You seem to be idealizing these bunkers into easily destroyed buildings instead of actaully trying to get inside the head of a bunker builder.

As I said, keep it up. I'm sure it will work out well for you. You and your non existent IR cameras.

You have confirmed my accusations.

The fire isn't to destroy the bunker it's to destroy the surrounding natural cover so everything is really easy to see.

I'm not trolling you're just mad I am upsetting your bunker fantasies and it's hilarious.

youre entire scenario requires you to know where the bunker is and have a large group of people to siege it.

good luck convincing a bunch of people to wander around the woods looking for a camoflagued entrance. most people place these things in rather isolated areas so you'd need to bring in supplie trains to supply your people as you hunt for the bunker and destroying all the natural supplies to attempt to get in is counter intuitive the entrances are usually hidden and if you've ever played hide and seek in the woods a little camo goes a long way.

and its not like people who make these things arent prepping for nukes that release poison gasses and such so theyed have filters to remove things like smoke.

better off just raiding something not ment to stand up to a raid.
