How about a Doberman? A friend of mine finds no need to even lock his van
when his Doberman is in it. It won't even let me into the van without him
there even though it knows that I'm ok. Nobody gets into the van unless
they have either a bullet or a tranquilizer dart.

Yup. I did this after I posted this post:

http://home.maine.rr.com/randylinscott/jan20.htm

You know, I worked in Andover MA 27 years ago, in a building shared with
Raytheon. A lot of cars there, and there was a rash of burglaries in the
parking lot.

A guy I worked with who was really smart came up with a circuit very, very
similar to this one. I installed it in my '80 Corolla, took an end
connector from one of the units I was working on, put a key switch in it,
and a plastic cap and mounted it in the fender well. It worked quite well.


That's why I had asked about a 555 CKT.

Ah, yes. The trunk monkey!!!

Too high maintenance, though. Can they be litter box trained?

You couldn't handle a "30 ft" anaconda.
Plus it would pee in your car,and STINK it up.

I had an alarm in my 94 Integra,and Jun 29,at 3:40AM,it went off,I
immediately looked out my window,and they were already rolling my car
away.I jumped into my shorts,grabbed my gun bag and ran out,and the car was
already out the gate and well down the road,alarm blaring.(a gated
community!) All this in less than a minute.

It had a starter disable,that's why they pushstarted it.
I had a fuel cutoff relay I was going to install with a hidden magnetic
switch,but didn't have a chance to do it. The car was 'recovered' 3 days
later,two counties way,stripped and burned,a total loss.

Hondas are really easy to steal,up until they began using immobilizer keys
and coding the ECU to the keys.

you need to immobilize the car so they can't drive it off;meaning a fuel
cutoff or removal of a critical part like the ECU,and the alarm is just to
tell you they have gotten INTO the car and may be removing your stereo,air
bags,seats,or other parts. Then you need a GUN to safely 'detain' them
until police arrive,which can be a long wait.In some states it's legal to
shoot the thieves,especially if they move towards you.
