Mobile Phone Alarm for a motorbike, car or anything you want

I got fed up with normal alarms making a lot of noise, and no one taking any notice of them any more.

Also not knowing if anyone had messed with my bike because I was to far away to hear the alarm.

So I decided to make this alarm using an old mobile phone and a simple timer circuit.

The basic principle is if the motorbike is moved it will trigger a timer circuit,
which will send a 3 second pulse to a mobile phone, which will phone me to let me know that something has moved my bike.

This project is not just for a motorbike, It could also be altered you warn you about anything you want.
ie house, shed, car.

Step 1: Items needed

1 old phone with speed dial.
1 mobile phone car charger.
1 555 timer chip
2 relays 12 volt
some tilt vibration switches.
some resistors and capacitors
some wire
a small plug and socket. (a phono plugs is ideal)
Some electrical tools and a little electronics knowledge.

what are the volts of 13k resistor and 220uf? pls give thanks

[silverwindro]

Hi, i`m having a noob question, how do you enable or disable the alarm?
If i put it in a car, how do i disable it when i open the door?

[wakojako]

TBH I don't think this would work very well in a car - If your car is moving, it's gone. An opportunistic thief might try to push a bike away in neutral, unlike in a car.

[ninja_joey]

This is awesome! I have an alarm in my bike already but it doesn't even chirp from like 100 feet away,despite it's claim if 1/4 mile,or something like that,range.

Some of this stuff seems a little hard for me since I am beginning to understand schematics and know how to wire it all up,but I'm sure my electronics instructor and robotics club mates can lend me a hand...

I too would like to do this instructable and wire it to me already existing alarm for its siren.It has a nice screech to it.

Any further help would be nice.

[salikkuraishy]

thats really nice idea :) bt i would want help !!! i am living in India and there lot of thieves !!! bt wot dey do is they steal bloody petrol nd i really want to catch a person red handed !!!! so any idea connecting this with petrol pipe ??? i even had petrol lock bt they tampered it :/ nd i cant get any evidence my bike is yamaha FZ16 please help me out and thanks :)

[arifpulikoor]

pls, add this projects complete diagrum

[saleelsayeed]

hi
pls suggest any optical sensors that can sense any attempt of theft

[shazaad mohamed]

hi
can you please give full report of ur project and i need clear circuit diagram of this

[nfarrow]

Would be cool to use this same technology without a cell phone, maybe use a walkie talkie since they can transmit now over 6 miles.

[zerdent]

man you guys stole my idea lol,, all i was gonna do is use an old i mean really old with quick dialing capabilities and use couple transistors, a mercury switch to turn on and dial your phone number (your new one) and to alert you when they try to straightened and move your bike,,,, simple but effective

[simon72post]

Hi dev6862 the easiest way to add a phone would probably conect a timer circuit to the siren. so when the siren goes off it will trigger the phone the only dificalty you will have is if the alarm beeps when you arm or disarm it. it will trigger the phone unless. you make a time delay.

[malkandi]

Can you please make me a devise which should connect to a alarm in my room and when ever my vehicle is moved away by a certain distance the radio connection gets disconnected and the alarm starts. My car was stolen just a few months back. Thank you

[nissans]

If the bike is put in a truck, as so many are, the alarm should be silent and device hidden.
the phone should notify you so you can log in to track it via the gps function,
alert police for rapid recovery before device is discovered or bike is striped and dumped.

[bumsugger]

Hi there,
I did originally see and like this Instructable some time ago and I noticed that you stated that you had a "future plan" to update the alarm by including a facility whereby you would be able to call the call the bike and trigger the alarm by remote control,for instance if you were in sight of the bike but were some way off,and it was suffering someone interference of some sort.Did you ever get to round to incorporating this feature?

[tokymaru]

how would go about using the phone with/instead of the siren from the original alarm, using the original sensors?

[jimmytvf]

i've thinking for a while of making a "mobile alarm" with an arduino, but this is way easier. consider the possibility of adding a switch to disconnect the alarm system when you're on the road. my idea is, instead of calling you, call directly to the police and also trigger one of those voice memos saying something line "this is a call from a motorbike. is being stolen right now, please backtrack the mobile signal to get to it. please don't hang up to track the signal. thanks" and will catch the thieves on the run.

[tokymaru]

good idea, but more often than not (at least with cars) the alarm is set off by it moving alot; ie something hitting it, or it being broken into to steal something, not necessarily it being stolen. alot of times, especially if its a sensitive sensor, the police don't really need to be contacted unless a report needs to be filed.

[amrit0003]

i had made this project before you,but i implemented it in security system ,and used microcontrollers

[ardvark]

love the project I had a similar idea a few years ago but never got round to working out how to do it why not make use of the mobile phones camera and gps sim card location that way you would have a state of the art alarm and the evidence you need to parse on to the authoritarians.

[DoubleTrouble]

Good project, I'm not sure if anyone mentioned this, but couldn't you just wire the phone into the battery to keep it charged. Maybe with a trickle charger or a timed charger as not to drain the battery?

[carlo$]

Brilliant!

[Cosmic Cat]

This is a great instructable! I have one observation though. The old phone that you use to dial your primary phone has to be currently activated right? In other words, it has to be in service or it won't be able to dial out and make calls. I didn't think you could use any old phone without it being active. Could you clear this up? Thanks

[jsgraham]

@Cosmic Cat... You would definitely have to have the phone in the circuit active. Basic cell phones are a dime a dozen nowadays. In my experience, most of the "basic" cell phones released in the past couple of years, can be activated on a prepaid plan through local "mom & pop" resellers. "Basic" as in just simple texting and calling options. I had an old AllTel phone that I activated through a reseller on a simple prepaid plan. Tracfones, Net-10 or other prepaid phone will fit the bill. If you're only going to be using it for this purpose, the cheapest plan possible should do the trick.

@ simon72post... This a great instructable. I've been looking for an affordable alarm for my bike. Thanks for putting this together.

[srilyk]

Also, a lot of pay-as-you-go plans have no expiration date on the minutes, and they only charge on the days you use (at least at&t go phones).

[Kasm279]

If you use a tracfone, make sure you look up stuff on the battery life first! My Motorola-but-not-Motorola w376g gets two days ON IDLE....

[paul0vi]

thanks it is truly incredible, the best idea ever,
I salute you with respect

=////=======> ~ Say, Remember those old McDonald's Pedometers.?

[Emberblade]

i like your  ideas, however, it might be more prudent just to make the audible alarm go off as the tilt switches activate.

also, i know my bike has a lock on the forks to keep it steered in one direction, which have been fairly helpful in the past....

another thing, if you were to put a switch on the leads to the battery, after the alarm systems of  course, then you could make the immoblizer to kill the power to everything except for the alarm.

Great Instructable!  cheers ,   E

[eschneck]

Just a word of advice - the fork locks are worthless. My 4 day old Suzuki GSR-R 750 was stolen because I left it locked with just fork locks. All it takes is 1 or 2 people to lift the front end (or the entire bike) and it's gone. Live and learn! :)

[WolfTohsaka]

Hello Emberblade,

You're lucky to have the park position sufficient to prevent steal from your region of the globe !

here motorcycle theft is more like :
- check if motorcycle is valuable
- check if it is attached to a pole/smth
- cut the rim if attached by rim (motorcycle rims are more fragile than SRA/FFMC rated anti-theft devices)
- lift the motorcycle
- drop into truck
- sell motorcycle
- GOTO 10

well, you get the drift.

So, in that case, audible alarm as you say can be useful. And for the immobilizer, never cut the battery. on recent bikes like mine, you will cut everything electronic and the bike will put itself to default and you will lose the setup (daily km, hour, ...)

the best thing on carb bikes is to cut spark ignitor. because if you only cut starter device, you can still push the bike in 2nd gear.
on injected bikes, just cut the crankshaft position sensor. it will make the bike shut down properly / prevent it from starting.

Eschneck,
If the fork locks are not you thing, a rear disc brake lock could prevent theft, then of course, the old standby for city living, chaining you bike to a pole.

WolfTohsaka,
That's true about the electronics bit, losing you settings and all, I never considered that, my bike is from the 80s, a kz 650, so I don't have any computers on it. And yes, I agree that cutting off the spark ignitor or the crank sensor would be the best idea for people with a computerized bike. Where I am, bikes are stolen fairly often, in fact once I saw my friends bike up for auction on eBay only a week or so after it was stolen from him! Crazy world we live in, but that's the beauty of this instructable! Now i can have a contingency plan for when someone tries to ride off on my bike. Hopefully, I won't need to use this, as my current system of chaining it to a nearby pole works brilliantly, but if I had to park it somewhere I wasn't familiar, I would feel good with this added protection

Best

[WolfTohsaka]

Emberblade,

Actually, crank sensor is betten than spark ignitor, because the ECU shuts down properly, whereas spark cut, it still puts gasoline.

On a 650KZ, it is the only solution, only thing electronic being the blinkers :p

Chaining to a pole is one of the best solutions IMHO.

I do use a disk lock device with embeeded alarm, and a U-type lock when travelling to protect my bike (V-Strom). alarm disk locks can be found on ebay for something like 20 bucks.

I use it not to prevent theft, but more to prevent bike-fiddling,

[Emberblade]

so basically you wired the leads for the phone system right into the immobilizer from the other instructable?

[frikkie]

Hey.For step7 were you call the bike and let it cut out or make an alarm.If the phone usualy rings then you gonna get power that like let the phones backlight come on.If you can tap some power from there to trigger a transistor and maybe in turn a cut out circuit.I know with the car alarms when you cut out ignition or fuel then engine starts to loose speed and cuts out.

[davidpaul23]

in this case if i use the vibrating switch ,as soon a i strat my vehicle then again my phone will be keep on ringing is it ,so wat can i do if is this is in case 1> and another basic is if any unknown takes my vechile this is ok but i want my kit stop ringing when the owner of the vehicle take, so please give some suggestion regarding this factor

[frikkie]

If I may..The trick is in the way you connect the circuit to the power supply. I would for example add one more relay that connects the timer to the positive supply when the bike is switched off.How do you do that? Simple you have to take a relay which have a normal closed and normal open positions.Now when the relay has 12v on its coil the contact is closed.The circuit connected to the normal closed,doesnt get any 12v.When the igniton is off..the relay's coil falls back to the normal closed position arming the alarm.

[dev6862]

from where i can get tilt & vibrating switches????

[simon72post]

I got mine from maplins in the uk

[davidpaul23]

hi, can you please give me a clear view of the circuit above please...

[simon72post]

If you want more infomation on the timer circuit have a look here.
