Homemade Alarm System

[sysco90campos]

Is the siren power supply AC or DC?

[cyberelectronics]

@sysco90campos DC

[sysco90campos]

Ey im trying to do the same project what is the circuit connecting to ,i know is the cell phone, alarm siren, keypad am I missing anything else? Please get back at me, I really appreciated

[cyberelectronics]

@sysco90campos Pls read the description for details

[matthew3558]

did any one see the alarm that said HIV lol

[alistairism]

how did you make the phone call the other

[cyberelectronics]

@alistairism Hi.

Two wires connected to the phone PCB (Speed Dial button) then using an optoisolator u can make a "short circuit" for initiate a call.

[alistairism]

@cyberelectronics thanks

[nomanbashir496]

plz send me the details of this project to my mail address.

here it is

@nomanbashir496 Please read again the updated video description.

Very Good. I like your project. I am admirerd you. although i am very interested in microcontroller and arlam circuit, i have ever finished a project for microelectronic circuit.

I am in VietNam. May be. Because of material deprivation, I have never had a project as your project.

Can you help me for your projesct? I am very looking forward to your helping.

my email: josdoaitran@gmail.com.

(because Iam Vietnamese. Therefore I use Enghlish not good. Hope you understand!!!!

[cyberelectronics]

@josdoaitran Thanks. Mail sent :)

[carlo23lee]

hi can you help me how to do that im doing a project realy similar to you can i you send me the circuit diagram if posible all the info thnx that would be a great help 4 me...

[Mr94transam]

Hey great project. I am in college and as my final project, I have chosen to build a security system. If you could, please send me the schematics for this. I think my Instructor would like to see how this one is made. Any help would be great. My email is mufflers_28@yahoo.com.

[79wirenut]

sweet like the key pad. I did the same thin with 2 cell phones. I'm using the same siren & I recoreded the siren so when the alarm phone calls my phone sounds like the alarm.check it out !!! let me know what you think.

[kopaszss]

Nagyon jó! A lézerek útját meg lehet hosszabbítani tükrökkel?

[cyberelectronics]

@kopaszss  Kösz. Persze.

[PS2djX]

song name please ?! so cool !!

[cyberelectronics]

@PS2djX Shockshadow - Sunrise. Thx.

[Tabby266]

Awesome setup. All i really have to say...

[TheFirealarmfan]

@Tabby266 What! Why do you have to stalk every channel.

[Tabby266]

@TheFirealarmfan I dont.

[Tabby266]

@peanut9357 Put an armored cage on it then.

[xboxdisc]

What did you use to interface the phone?

[cyberelectronics]

@xboxdisc Optoisolator and 2 wires connected to a speed dial button in the phone

[cyberelectronics]

@peanut9357 This is a demo project only

[mlst1206]

@peanut9357 its for experimentation only.

[cyberelectronics]

@peanut9357 what about mobile phone jammer :)

[anglianchannel]

I have built several of these using a different technique and sold them to customers no problem

[nwpamundsen]

too much time on your hands

[malabares14]

BAD ASS!!!! BAD ASS!!!!

[maxey83112]

dude this is a bad ass set up u should get a patent on it good job can u tell me the basics of electronics to get me started on some projects like these?

[cyberelectronics]

Google can help you a lot.

[chiter200]

SMART

[VMFA115Starloric]

Gee, that's inconspicuous

[wowlaxis]

lol that whould scare the shit out off me xD

[brokenarrow2222]

love it. seem to complicated.

[flamedrag18]

damn, awesome set up, you should try to market these, you ever know?

[cyberelectronics]

Thanks.

You cannot sell legally any products like this, without certifications.

As you can see I make only DIY projects and I have only a single unit (the prototype) and I didn't want to sell it :)

[jlaudio10w07]

great set up... ive done a few w/  an omron dc supply, A/B minisight, a carlo gavazzi multi timer, and a banner laser...

[auburntaco]

Could you possibly post a video showing how to use a prepaid phone on a standard alarm system to relieve the need for a land-line? I have a Honeywell alarm that's monitored by Monitronics. The monitoring is $33 a month and the phone line is $25 a month. I'd rather buy a prepaid phone once and save that $25 a month.

[cyberelectronics]

If you have an alarm system monitored by a company:

- ask the company about the GSM module (but I think such companies doesn't offer GSM connections, because the GSM signal can be disturbed easily; the land-line connection is much safer).

- you can't connect a simple prepaid cell phone to a monitored system (the company will not allow this).

[auburntaco]

Do you know how I could use a prepaid phone with my existing alarm system so I don't have to have the land-line phone?

[cyberelectronics]

1. You can buy a special GSM module for your alarm system.

2. Or use a cell phone with speed dial function, connect 2 wires to one of the programmed speed dial button.

Connect the wires to the contacts (Normal Open) of a small relay.

The relay coil can be connected directly to the alarm siren (12VDC), but don't forget to connect a protection diode (ex.1N4148) in anti-parallel with the coil.

Or you can use a optoisolator, with current limiting resistor on the LED side (like in this project)

[pianoexpert11]

how do you make it .you did not show us .comment back please

[cyberelectronics]

Hello

In my youtube profile, you can find a link to the website.

[AnonymousJuan]

Pretty cool. I wish there were kits like that that I could just buy.

[aliencurv]

Hey nice work! i thought of sing a pre-paid cell phone also but i wasn't sure if they had a serial port. I guess i'll have to look into it now! :)

Thanx!

[cyberelectronics]

You don't need a serial port. You need only 2 wires, connected to a speed dial button, on the phone keyboard.

[aliencurv]

A yes! you are a smarty pants!

I was thinking of sending SMS... that's why the serial would be a beauty . But i also like the idea of just receiving a phone call from it . Let's go with that ! thanx

[elmeister4evayoknow]

I always see your experiments and constructions, is "poetry on movement", you're the one, you're the best man, kudos!!!

[MJElectronics]

this video is full of information , thanks

[vnbong609]

did you use a prepaid cell phone for the dialing phone? I'm thinking about buying a prepaid phone for mine so I don't have to pay for a land line. So you have to program the phone's speed dial and just have it 'dial' the button for that particular number?

[cyberelectronics]

Yes, I use a prepaid cell phone.

Exactly.

[cyberelectronics]

Yes, this is a simple car alarm siren.

[Athonymus]

man u rock it´s realy awsome^^

[Athonymus]

man u rock it´s realy awsome^^

[morto360]

hehe.... thats smart! nice work man!!!

[morto360]

nice project! you should make more sensors so u can controll stuff like, break or open a window or door. how do you control the mobile phone??

[cyberelectronics]

Thanks

Using only 2 wires (optically isolated), from a Speed Dial button, on mobile phone.
