okey, so my friends thinks hes really cool when he takes off the ignition wire on my moped.
(its a Derbi DRD Devil since you really wanted to know http://koti.mbnet.fi/isaksson/senda_r_black_devil.jpg
so i plan to make a anti system with very loud sound, he is a little oversensetiv to sound, he starts yelling that his ears hurt when i clap my hands.
so i when to the store and bought me a rape alarm, its rated 120db so i think he will begin to cry.
i specifically chose a type that you have to pull out a pin because i thought it was like the circuit was broken and the thing started to make sound, i was wrong, and its here i need help.
i need a circuit that turns on when a connection is broken, like the opposite of a transistor.
i don't have time to be fuddling with microcontrollers because the only microcontroller i have a programmer for is a Basic Stamp 2 beginner thing and its to big to put in my moped
if anyone know how i can do this please tell me.
