Hello, i want to build own car alarm system. I have seen some scheme
based on Microchip, but i'm interesting a more theoretical knowledge
about this and your tips and tricks.

Thnx and sorry for my bad english

1) It must be reliable. If it has the capability to stop you using your
car, it must work every time. So keep it simple, and build it to last
forever.
2) Much of the benefit of a car alarm is lost if the system is a well
known arrangement. A hidden switch might be enough! I'd welcome other
people's experiences on this particular idea, though. A flashing light
is a useful way to stop the non-professional opportunist.
3) You didn't say whether you wanted to prevent entry or just
immobilise the car.

If we all drove Jugos, the need for car alarms would be eliminated. :-)
