Super loud security alarm

This instructable addresses personal security. Yes, there are $20 PIR (Passive Infra-Red) motion detector alarms out there you can get at Walmart or Radioshack, but why not make one that can
1) Communicate verbally and...
2) Be loud enough so that IF it happens to go off, EVERYONE around will know, and (hopefully) call for help.
We all know that many of those battery-powered, $20 alarms that come with double-sided tape that you can mount aren't very loud, and if you DO happen to have one that is REALLY loud, it is your professional, built-in multi $K wired security system. Well, this one uses a microcontroller, which means you can wire the sound output to an amplifier, be it homebrew (DIY) or one from the store.

Here's a video of it in action:

Step 1 Find the stuff

Here's all that's used:

• Parallax BASIC Stamp IIe microcontroller
• Parallax 'Board of Education' carrier board
• RGB LED (I used THIS ONE)
• 220 ohm resistor
• Some solid core wire
• Parallax PIR sensor (you can buy it online, or get it @ radioshack)
• Emic TTS module (from Parallax's online store; I was going to use this for another project, but that one was too big and expensive, and I never got around to it)
• Male header pins (I used THESE)
• Power supply
• Sparkfun connector wires (or any other wires that have crimped, plastic-housed, female connectors on both ends). I used THESE.

Great instructable. It is sad that we live in a world where burglar alarms are necessary but it is important to keep yourself safe.

Do you think you could set up a way to add more than one PIR to the circuit or would that require a different circuit all together.

Ohh yes of course; this uses a microcontroller with 15 I/O pins! You could probably have 10 more if you wanted.

Nice job. I built something similar with the same type sensor. Mine is connected to my computer that sends a message to my cell phone.

Hey I just had someone break in to my car bashed my window in. How do you make that device you just mentioned. I want to be able to be in control. So when someone breaks in again it will beep my phone and I will be out to my car faster than lighting. How do I make that device!?!

id hook up an electric fence generator to the car door and frame so when someone touches it ZAAPP and that can be de-activated with the key chain remote

I hooked the output of the sensor to the button on a remote. I have a ir receiver hooked to the serial port on my PC. I use winlirc and eventghost. The computer is on all the time to record TV programs. I arm and disarm it with a separate remote.

Just get one of those energiser alarm/flashlight things and tie it to a tripwire.

[pyro man]

dude ur like everywhere

[Thelonelysandwitch]

im everywhere but nowhere. if I am where you are then im hidden or somewhere else.

[pyro man]

iv also seen youas capn tac and one other thing but i forogt where it was

[Thelonelysandwitch]

when was I capn tac

This is cool. Nice job! I've been looking for a good design like this. 5 stars.

Cool! Great Instructable! Thanks Joe

Thanks! Doesn't look like other people have seen it yet...lol
