Do It Yourself Laser Home Security

Were you ever amazed at the laser alarms we have seen in many action films? Have you ever wished you could have one for your home? Would a laser security system in your home help you sleep better and leave you at ease when you are away? Now you can make one by yourself thanks to Kipkay.

The Do It Yourself video below provides step by step directions how to make your own laser home security system. It tells you exactly what materials are needed and how to put it all together.

Unfortunately, this DIY project is not as simple as one may hope, since it deserves some soldering, electronics, and actual work. In addition, because it is made as a home security device, it should not be just put together with haste but done correctly.

While it may not be as intricate as the ones we see in the movies, it is pretty impressive and effective.

If you do decide to take on the task of making this project come to life, we would love to hear how it went for you.

Have Fun!

    dear tai siach,
    I like your project on laser base home security.

    Would you please tell me, list of components requried for the
    reciver circuit so whehnlaser beam get distract siren will get on.
    or wher i will get this circuit.

    dear tal siach,
    i like your project of laser home security. can you sujjest how can i make pcb cicrcuit so whenever this laser beam distract.
    siren will get on.

    would you please give list of spares to make this part of circuit

    Can the laser detector be customized to detect a foreign object in a pile of sheets (i.e. tissue paper)? Thank you very much..

    I think this is a great project.
    The Photocell should conduct when light hits it causing the base voltage to be reduced. But the schematic shows the source voltage going directly to the base rather than through the POT wiper and one output through the Photocell to grnd and the other output going to the base.

    FYI for the person concerned with the siren voltage, most are designed to run on a voltage range from 6-14v (Radioshack 273-079).

    To the guy who mentioned the 555 timer, it would be great, but after reading some of the posts, most should just try getting noise out of the siren.

    For the guy that said “buy a shot gun and know how to f*cking use it”, you would need to be home in order to use it on the burglar…some people really don’t think about there answers.
    And burglars normally do run when there hear a sound in an empty house, especially if its a This circuit is flawed…

    The siren, a 12V siren will not run on a 9V battery correctly, even with a transistor of that spec in place.
    Burglaries take place mostly at night, the burglar would only cut the power if you lived in a wealthy area and a wealthy household, in that case there would have the tools to do this successfully and would have properly bin planned.

    Don’t use this system as a proper alarm in many cases unless you live in a high crime rate area or live in an area not so wealthy, it is mainly for a bit of fun for the average person.
    And for £20 its really not a bad buy.

    Food for thought here… any burglar that has broke in before probably knows the police response times in his area, usually 5 to 15 minutes, (I forgot where I got this statistic but it may be off…) in that time he/she(?) could have all the families valuables and be driving away in a family minivan. In the event of a break in you cant count on the police, the swat team, brinks home security, or the ice cream man. Simple advice, buy a f*cking shotgun and know how to use it.

      I agree! I heard somewhere….When a crime is being commited you only have seconds to respond and the police are only minutes away! That is even scarier then someone trying to break in! Learn the gun laws in your state and train so you do not over react. I will always be afraid if someone tries to break my door down at 1am.

    hey guys … very, very cool project for the home… but how about camping in the rough and wanting to be warned of bears in the area . a portable unit set-up for batteries would be cool.. let me know know ,,,,,please .

    a 555 timer is needed in addition to the circuit, so that the alarm once triggered runs continiously till the time u wanna

  11. matthew.

    i dont know what i need to make it i need a list and i need to know what holes it goes in like a picture from above and how to solder them like do you touch the wires to the other wires to make the connection i dont know how to build it
