so here is the idea, a project box with keypad for arming/disarming the alarm. a three axis accelerometer that senses its position at activation and sounds an audible alarm if movement is detected. It needs to be compact about the size of a deck of cards and dc powered. it only needs to know one code for arming. I know there are alarms that do the same basic thing (for bicycles and such) but isn’t it more fun to make your own. feel free to slam and bash the idea, I know it will happen anyway.
Should be a piece of cake:
