And come up with a Cheap-Ass alarm.

On the Mazda, I don't want to go to the trouble or expense of installing
a real alarm, but I want something.

Honking the horn and flashing the flashers would be good enough. I want
the horn to 'beep', so a flasher unit and a relay or two would be good.

There's two ways to set the thing up:

Put something like a key switch under the fender, turn on when leaving,
turn off when using the car.

Or, a little more sophisticaed: put a switch inside the car. Now, this
would mean triggering the 'alarm' when getting into the car, something I
don't want to do at 1 AM when I'm leaving on my 'paper route'. So, some
kind of delay would be good. I was thinking a capacitor between the hot
line and the 1st relay, so the cap charges and when it reaches charged
it triggers the relay and starts the flasher.



All I've read so far are questions about how the car owner would switch
an unidentified alarm system off and on. Since you are not buying an
off-the-shelf alarm what kind of alarm system are you proposing. And
more importantly how will the alarm be triggered by a potential
intruder.



But, I need a hint what size cap to use, and how to wire it into the
relay so that it charges before setting off the horn, maybe 20 seconds
is good.

Of course, we could get REAL sophisticated and use the ol' venerable 555
timer, but that's more involved than I want to make it.

Any ideas?



Why not just have a scr trigger from the interior light? The scr will
switch the horn relay to ground. Door opens, light switch fires SCR, horn
blows until someone turns off the hidden (under dashboard or seat) switch,

Because this would blow the horn when *I* open the door. I leave at 1AM.
But I don't want a delay. A key switch with a cover outside would solve
this.

which breaks the circuit to SCR. You could use a capacitor to give you a
few seconds to leave or enter the car.
After thinking about it, you may have to use a transistor to invert the
signal from the door switch. You could set up your delay with the
capacitor, resistor, to wait 10 or so seconds before firing the
transistor, which would then set the scr. Back in the 70's when the price
of gas was rocketing, people stealing gas from your car at night became a
common occurance. I thought about attaching a small magnetic reed switch
to the gas cap cover that would do the same thing. Just never got around
to doing it. One guy I know wired a 120 volt hot wire to the frame of his
car. I wouldnt recommend doing this though, it could kill someone and give
you a manslaughter charge.
(I know, it shouldnt be against the law to kill a thief, but it is.)

I like the way your friend thinks. Who cares if the theif gets fried?

Guess they must have shorted the battery somehow, officer!

All I want is something that will blow the horn, and maybe flash the
lights.

In it's simplest form, a switch mounted somewhere outside the car that
turns the system 'on' by providing a ground path for a relay. When someone
opens a door, the relay closes, current is passed to a flasher (like for
your turn signals) and then to the horn and headlight relays. Very simple.

Also, this is instantaneous. As soon as they open the door, the horn
starts. There is an 'always on' current source (courtesy lights) that do
not turn off when the dome light is turned off, so I intend to use this
for the 'trigger'.


looks to me like you have it all figured out. So why are you asking us this?

You know you could give away your secret device.
For instance, from this conversation thus far, if I were a crook, I
would know to look under the fender of your car for a keyswitch. Then
take a sharp chisel and hammer and shear the switch off, then cut the
wires to the switch, then get on with business as usual.
Sometimes the best intrusion device is to catch the crook offguard.
I kinda like the string tied to the toe suggestion. Ive heard it works
for napping while fishing too.

Basically, wanted to see if it was feasible. (If anyone would say, "I
wouldn't do that if I were you...").

I was an elec. tech for 19 years, and a geek for the past 15. I know my
way around a ckt or two...

As far as giving away a 'secret', if these guys even know what Usenet is,
I'd be surprised.

Either that, or they'd post a message like, "This is a great site!"

One of the reasons I left. (I used to live in RI).

Biggest complaint: Idiotic handgun policies for law abiding citizens.

Biggest hassle: High taxes and auto insurance rates

Biggest disappointment: Them thar' politicos keep on makin' the same
mistakes and the dumb public keep on electin' 'em!

Oh, and don't forget the copious amount of salt/chemicals used to de-ice
the roads and eat away on our cars. Which brings us to COLD winters
that are far too long.

Other than that, it's beautiful country...
