Anyone familiar with basic electronics can wire this system up in about 2 hours.

Just wondering, what would you pay for a system like this, if anything?

more details please.

How does the phone integrate, what kind of software is required, what does the cable do, where does that big box go....?

I think he just put his phone there for a size reference. But if it would call or txt you when some one was screwing with your bike that would be real cool

The phone is just for size comparison.

The unit will fit in 1/5th the size of the case it is now in... I just had the black project box handy. It could be made to go behind the fly screen, under the plastic airbox, or under the seat.

No software is required, it uses simple circuits, no digital ICs... keeps the unit low power since a bunch of resistors and caps are the only thing eating eneregy...even the alarm is piezo.

Cable is just hooked up for vibration trigger. So if someone grabs the leathers or helmet it will trigger. The idea is when you go to the mall you run the cable through the jacket arm and helmet so everything is locked down to the bike. Could very easily put a pulsing current on the cable to trigger if it was cut...

I fantasize about hooking up a shocker circuit to imbolize intruders...if it wasn't for the liability can of worms.


Does not page phone now...I have a module I can add take snapshots based on digital image algorithm or body heat detection...will store images in unit or email them to your phone using a wi-fi connection. The camera eye can pan and tilt remotely with phone browser. Everything is configured and accessible through standard browser. This unit is running embedded linux with apache server software. Unit runs off 12v. This type of controller part ranges from $200-400.

Also, I am not ready to sell units. This is just a working proto-type.

I wanted an alarm that could protect anything:car, buell, bike, trailer, boat, house, hotel room, farm land... It could also have covert operations applications.

The unit as shown in picture is a DIY-radio-shack project...about $50 in parts.

If there is interest I will post info to make your own.

It would probably be more cost effective to re-purpose a car alarm if paging is needed.

Radar microwave sensor with adj. coverage, warning beeps if bubble is broken.

What about this? How does it work?

Pretty slick stuff, you should market it when you get all the options worked out, and are happy with your results.
Nice Job!

The radar/microwaves are emitted and use the doppler effect to determine if something is moving near the unit. When everything is still the unit sends out a wave at a freq. and it comes back as the same freq. If something is moving the freq. will be higher or lower if the object is moving to or from the unit.

The sensativity adj. is is the allowable window of frequency that corresponds to to movement. The distance is how far the unit throws the waves (amplitude).

This basically what bats do. This is better than IR (body heat) detection because it goes through glass and steel better than IR detection can do.

A two zone radar unit can be found on ebay for about $15. I went to my local car audio place and paid the impatience tax, I had to dish out $70 for a single zone unit.

For the cost of a value meal you can build one of these alarm circuits that will give you the foundation. Everything else is like slapping on chrome parts:

I've been testing the unit for a few days. So far so good.

I usually make adjustments to my projects that seem to stabilize after about 1-2 months.

I'll be using this for various applications, like protecting my mountain bike or surfboards while I grab a bite to eat.

Build it for a reasonable price, I would buy it.

I just brought something similar from Aerostich, but it doesn't have a perimeter sensor, something I really wanted.

Actually I would like a version that was big and loud, sized like a cinder block. I would love to chain the bike to it and if someone got too close it would chirp + flash a light.

I'm interested (under flyscreen model)

What's battery life?
Possibility of building in a battery cell (like a cell phone battery), and having a plug hidden somewhere to plug into a recharger when in the garage?

Shoot me a PM if you want to build me one, and how much I would owe you for "compensation".

I have that setup at home. I made it with x-10 components. For protection while at home it hard to beat. (I built my custom alarm so I can get the same effect to protect my grear while on the road/vacation):

I started with a setup like this:

-12v strobe ($12):http://www.smarthome.com/72701b.html

x10 relay ($4)
http://cgi.ebay.com/X-10-PRO-PSC01-Powerflash-Modu le-PF284-BRAND-NEW-X10_W0QQitemZ250068534257QQihZ0 15QQcategoryZ50583QQssPageNameZWDVWQQrdZ1QQcmdZVie wItem

-x10 heat detection($27):
http://cgi.ebay.com/X10-Hot-Body-Detector-Home-Aut omation-Kit-X-10_W0QQitemZ330066646412QQihZ014QQca tegoryZ50584QQrdZ1QQcmdZViewItem

Today my system is much more elaborate. I have prox. senors that set off warning chirps along with instant on vibration triggers (siren and strobe). I almost gave the paper boy a heart attack. If the basic setup does not give you the features your after let me know cause I probably already have it in my setup and can and can give you the info.

I would not be able to use x10 parts. I have no access to 110v.
Infrared heat sensors would not work for me either as I park in a garage with daily traffic. Every time someone would move a car it would trigger.

The only two ways to solve this would be either battery powered microwave system, or a crude electronic eye system.

I have used microwave sensors on previous car alarms, they worked well, except when rain, or foliage was present.

I just want something to protect my tiny corner of the garage...

Thanks for the offer. I'm still in the proto-typing and research stage. I have a friend who does electronics as a hobby. When he gets back in town I'll have a chat with him.

I think he would be interested in building unit for you at almost at cost of parts.

With regards with the cell phone, I'm thinking about making run off of any cell phone battery.

Then you would rotate your phone battery with your alarm batter every time you ride.

This means if you kill you phone battery you always have the alarm as a backup.

I'm still trying to kill the battery in my test unit...I'm thinking it will take weeks or months to drain the charge.

Fl - alright, keep me posted.

Good idea with the cell phone battery backup, but I wasn't implying I needed a backup.

My "idea" was to have a built in battery of some sort, that had the capability of being recharged. That way you could have a female plug tassle (or just a female plug tapped through the cast flyscreen supports) or something hidden on the front somewhere so you wouldn't have to worry about removing the flyscreen to recharge/swap batteries, just "plug-n-play".

Install Alarm
Let charge for "x" hours.
Unplug and ride, when done just plug in to re-establish charge.

Again, this is just off of the top of my head and I haven't put any real thought into it.

I know what you mean. I live in a community with people walking by my bike all the time.

Radar/microwave detection with adjustable proximity bubble is the only way to go in this environment.

Also, if you don't have a prox. sensor, criminals will look into your car and decide what they want. They will break the glass, trip the alarm, and grab your GPS/radar/packages in about 45 seconds.

With the prox sensors they don't get the time they need to window shop for your goodies.

Fl, talk to your electronic buddy to see if he would like someone to fund his hobby for a while.

A custom alarm is something I really could use.

That sounds like an interesting project.

I wouldn't mind having a proximity alarm for my bike. A strobe light to go with the
audible alarm would be a good addition too.
