I hate thieves - Requesting help building car alarm

[caphair]

So my gf's car along with another one in the same parking lot were broken into last night. They mangled her dash removing the radio.

It's gotten my blood boiling and I know most thieves can disarm modern alarm systems these days. I was thinking of making something that'd cause panic and make them bail before being able to steal anything.

One of my ideas is installing a set of super bright lights tucked behind the top part of the backseat where it meets the back window panel. Rig it to the some light switch that activates when the door is open and have the lights strobe incredibly fast and bright. Maybe even activate an annoying sounding horn. It could be turned on and off in the trunk and easily switched on when need be.

Any ideas on circuits and such to accomplish this? Thinking using separate power source as well

forget that.
start with a $75 chinese 2way pager alarm - because ultimatly only *you* give a shit.

then put the loudest sounder you can lay your hands on under the dash to make it painfull to get in the car.

finally, if you can get any electrically fired smoke or teargass cartridges that wont stain or soak into the upholstery - consider that too.

I like that. What's the $75 2way pager you mention?

I've made one before but it was for pranking my truck, not actual security.

And tap in an electrically fired smoke cartridge to it?

Re: I hate thieves - Requesting help building car alarm

only if you test one first in an enclosed area you dont give a fuck about.
you dont want it to stain or leave residue behind - that would trash the car interior.
and you need to see if it gets hot - some gas generators get hot enough to start a fire.

Re: I hate thieves - Requesting help building car alarm

Where do I find these gas generators? Only see fuses for them on eBay

Re: I hate thieves - Requesting help building car alarm

I wonder if strobe lights would be sufficient to scare off thieves, AKA fake Camera
Or perhaps a real camera that could take photos of the intruder...

Re: I hate thieves - Requesting help building car alarm

I imagine a super fast bright strobing light would cause panic for someone like a thief expecting a nice quiet dark area to "work" in.

It may cause them to think pictures are being taken or just startle them enough to want to exit the situation. Let's not forget the "slow motion" effect strobe lights create. Try stealing a radio now lol

Something like this: https://www.ebay.com/itm/291804493561

Connected to the door ajar switch so once open it closes the circuit and sets them off. I'd want to add a timer circuit that latches so if the door is closed they continue flashing for a set amount of time

Re: I hate thieves - Requesting help building car alarm

you cant scare off theives - they dont scare.
they expect an alarm to go off and work on the principle of speed - rip out your stuff & run as fast as possible.
your aim is to disorientate them so they cant work in the car.

or if your russian, you can kill them by fitting stun-guns into the headrests - something i saw on another forum!!!

Re: I hate thieves - Requesting help building car alarm

Lol. They expect an alarm with noise and outside flashing lights but not inside the vehicle. I'm curious how they'd react to that

[stj]

Re: I hate thieves - Requesting help building car alarm

lights wouldnt effect them, they could probably strip the parts out wih a blindfold on - a siren causes pain and a headache though.

besides, how many would you fit? if it's just one or 2 they could put a hand over it.

Sounds like kids or crackheads to me. Pros don't mangle the dash.
Piss them off and they are likely to vandalise the car.
Get a face off stereo, so there is nothing to steal or build a stealth stereo.

[stj]

Re: I hate thieves - Requesting help building car alarm

or replace the lighter socket with a bit of iron gas pipe with a 12guage cartridge in it and a solenoid on the back!!!

anyway, pro's dont take stereo's - they take the whole car.
they know that for example, the ECU is worth more than the radio

kids screwdriver the stereo out of the dash and then rip out or cut the loom.

Connect a pager to an electronically fired blasting cap and stick that in some C4.
Then just make sure you car insurance covers explosions

Ha! That gives me an idea of having some capacitors hooked up backwards and once the door open power is applied causing them to explode. Add some flashing lights, I think anyone would peace out of that situation lol

Re: I hate thieves - Requesting help building car alarm

Btw according to her neighbor they took some of his ID's and gift cards. What would they do with ID's?

[stj]

Re: I hate thieves - Requesting help building car alarm

if they are smart, they could go rent a car to strip,
otherwise they could sell them to a pro who could get credit with them.

hey - maybe they could use them in a gunshop to get that inline check done!!!
