Diy Projects For Anti-carjacking

[jimaroquai]

Problema natin ngayon eh how to secure our vehicles against carjacking right? Well I have some ideas which might help some of our tsikoteers who do not have enough budget to puchase those expensive alarm systems. Please take note na I will merely present the concept as it will be dangerous to show in this forum on how to do it step by step. On how you will do it? Use your imagination!!!!

DIY Project No. 1:

Marami sa mga car ngayun ang may automatic lock ng doors pag nakatakbo ng at least 25 km/h. You can take advantage of that by putting a relay with a resistor sa fuel pump at yung automatic lock naman ang magiging trigger para sa armature ng relay. Siyempre pag may carjacker off mo muna ang car para ma reset ang automatic lock. Pagandar nila at pag apak ng 25km/h ng speedometer ayun magsisimula ng magcountdown ang makina ng at least 20 seconds before maubos yung gas sa may fuel filter. That will give you approximately 50 meters of distance from the carjacker. Teka bakit may resistor? Hehehe! Cost of project: Php 300.00

DIY Project No. 2

Ano ba ang common sa mga manual at automatic pagdating sa transmission? Ano pa eh di yung reverse light switch! Same din ang concept gaya ng DIY Project No. 1, ang reverse light switch lang ang papalit as trigger dun sa armature ng relay . How to use? Simple, pag na flag down ka make sure to park in such a way na kailangan pa nilang i reverse ang sasakyan. Bakit kailangan uli ng resistor dito? Hehehe! Cost of project Php 300.00

DIY Project No. 3

Ano pa ba sa loob ng car ang hindi mo pinapansin? Ano pa eh di yung mga driver/passenger lights as well as yung interior light switch! Same concept din. The relay resistor (can be dispensed with). Pag dumating ang carjacker magbigay galang ka. Turn on the interior lights! Eh papaano kung pinatay ng carjacker ang light pagkakuha ng car? Yun nga ang silbi ng resistor eh. Bakit ko naman sinabi na pwedeng tanggalin yung resistor? Kasi pwede mo ring tanggalin yung bombilya para kunwari eh sira. Will it work kung nakadefault sa gitna yung interior light switch? Syempre! pagbukas mo pa lang ng pinto eh nagsisimula ng mag-countdown ang fuel reserve mo basta ba huwag mong kalimutan yung resistor. Php 300.00

DIY Project No. 4

Saan pa ba pwedeng i-tap? Hand break? Syempre coz meron siyang park light! Items relay and resistor. Php 300.00

DIY Project No. 5

How about power windows? Opo pwede dahil may power window lock siya. Php 300.00

DIY Project No. 6

Sa mga hindi mahilig magbusina katulad ko. Pwede ba ang busina? syempre naman! Eh papaano kung kailangan kong magbusina? Eh di maglagay ka ng separate switch para sa busina mo! Php 300.00

DIY Project No. 7

Teka puro electrical ang mga nasa itaas, wala na bang mechanical? Meron po. Question: pagnacarjack ka ano most likely ang mga gagalawin ng carjacker? manibela, pedals at stick? correct! Meron na tayo sa manibela at sa stick kaya sa pedals naman tayo. Siguro naman mas matagal gagamit ng preno ang carjacker kaysa sa clutch at accelerator di ba? So pag preno niya magsisimula nang magcountdown yun. Items: relay, resistor, separate switch. Bakit may separate switch? By-pass po yun. Php 350.00

DIY Project No. 8

Papaano kung hindi ako marunong ng electrical or mechanical? Siguro naman marunong kang magdasal noh

[leinahtan]

Pards, baka pede na lang pakabit sa yo. Magdadala na lang ako ng SanMig Light. How's that?

[key7wizard4]

paano ba maikakabit to?resistor is so cheap kung ito lng ang kylangan....

[ghosthunter]

Round 1 - How about a stun gun system wired to a couple of metal plates under the door handles... 100,000 volts powered from the car battery. That should be enough to shock the bejesus out of them.

Round 2 - So the carjackers don't want to open the door? Install a propane/LPG fueled flame thrower under the chassis below the door frames. Trigger using a foot switch and watch ten to fifteen foot flames shoot sideways from the car and fry the suckers.

[zero]

pwede kaya ang finger scan to start the engine?

[Bravoexo]

Gusto ko yung na feature sa Fifth gear.... bollards.

yup parang napanood ko na to sa tv... sa US ata merong ganyan...
sarap sunugin ng mga carjackers...

[vicoyski]

I'm pretty sure the carjackers know about these immobilizer techniques. That's the reason why most carjacks involve bringing along the owner for a ride and emptying their ATMs. At the end of the day, they'll drop the owner off, dead or alive, in some far flung area. By the time you can reach for a cellphone to immobilize the car remotely, they have, either already found and detached your immobilizer system, or have already begun chopping up your ride.

The best thing to do is just hunt down the carjackers! :fire:

Uy may bago na akong racket! Ehehe! It would be better siguro kung we will ask our electronics experts here in tsikot to make prototypes of my DIY Projects. I don't want to mess around other people's car kasi.

By the way, I am actually doing a DIY project myself pero combination ng mga nabanggit at may naka attach na cellphone din. Don't be afraid to try pare. You can actually test and retest your prototype without attaching it first sa iyong ride. I am not an expert sa electronics, puro common sense lang ang gamit ko. Technique? When you are going to buy a relay sa auto shop ask the seller kung saan pwede gamitin ito. Go to an electronics shop and buy a resistor. Ask again kung papaano mo linyahin iyon to get the desired results. Ask mo na rin if you are buying the right resistor. In the end, you are getting free consultations.

By the way, I don't drink na pare. Nag quit na ako years ago.

Sa Round 1. That is possible pero it will definitely drain your battery unless you put a separate battery.

Round 2. Possible din, pero hindi kaya abutin din ang gas tank mo?

[jimaroquai]

Pwede, but that will defeat the purpose of this thread because the scanner itself will cost you about Php 35,000, more or less.

[kinyo]

No, it won't drain the battery because such circuit will not require that much power, it has high-voltage but low current. The real obstacle is how to insulate the 100kV from the chassis ground. A 100kV can jump 3 inches of air.

However, the idea is cool. Using 1kV might be enough to give a painful shock and insulation would be manageable.

[beachbum]

mga pare, interested ako sa mga idea nyo. it's cool at mahilig din kasi ako sa mga ganito. tanong ko lang mawawala ba ang waranty ng car kapag nagkabit ako ng mga relays. TIA

[nugundam93]

nice idea ah. pero natawa din ako sa DIY #8.

[wildthing]

maganda ang most ng concept assuming pababain ka kaagad sa oto mo na kinarjack. as mentioned papaano kung isinama ka muna?!?

I am thinking na what if you control these fuel shut-off valves with a remote switch (just like the keyless entry remote) na hidden sa belt or pants mo (remember the old style pants na merun secret pocket?).

So you would "arm" your delay switch sa fuel shut off valve when you get off the vechicle...sisimple ka lang sa bulsa or sa belt mo when they left you off na.

OR

A remote switch na meron proximity sensor...so as long as the nearby ka the shut-off valve will be on. Pero pag napalayo ka na, mag-ooff na ito. Hindi ko lang alam kung meron nang ganitong electronic kits available.

[D4D]

Tama! Paano nga kung isinama ka muna at na-trigger na ang DIY mo??? Sabi nga ni Bitoy: "Yari ka!" Pero kahit hindi ka isinama, 50 meters lang? Ang mangyayari pala, pag-iwan sa iyo, dapat karipas ka talaga ng takbo in the opposite direction ala the Flash! At kung may back-up car o motorcycle na kasama, "Yari ka na naman!"

Nice ideas though kaya lang di ako marunong ng electrical/mechanical. Baka pwede pa-demo naman.

Actually meron na nito and nasa divisoria ako last weekend to look for one. It is a keychain with a tweeter. yung 1st part is nakaattach sa key chain while the 2nd part may be kept inside your pocket. kapag napalayo sa iyo ang mga keys mo eh tutunog siya.

ano ang idea dito? pagbaligtarin ang use nila. Use the 2nd part sa armature ng relay. Tanggalin yung tweeter at connect it to the armature ng relay. but you have to look for a low voltage armature which can react to at least 1.2v of power. yung 1st part naman ang ilagay mo sa secret pocket mo.

Voiding warranty:

Relays are not that destructive. Kung nagkamali ka, you will only fry P10 pesos worth of fuse which you could easily replace. Just dont work your way towards the ecu.

In case na isama ka:

Well, you could consider putting a second switch sa gitna ng second row seats where you could have access.

50 meters is not enough:

Gayahin ninyo ako, I always drive with my rubber shoes on. Para mabilis ang takbo ko kung sakali

[wildthing]

hindi lang naman siguro 50 meters yun bago mag-stall ang oto...dahil nag-run out ng fuel..... ok yun key chain tweeter na yan...
