Moveable Doorbell

This idea is intended to thwart uninvited visitors in their attempts to smoke you out by laying on your doorbell. They can't ring it if they can't find it!

What this consists of is 84 small recesses about 2 inches wide with flip-up covers, like outlet covers, around your door, arranged in 2 adjacent rows of 21 lining each side of the door, each with a number on the flip-up cover. The covers are spring-loaded, so as soon as you let go it snaps shut. The panel in the back of each recess is a small electromagnet strong enough to prevent unauthorized removal of the doorbell, and the 'doorbell' is a small mobile device which, when the button is pressed, sends a wireless signal to activate the real doorbell inside. It is inside a steel case and held to the panel by the electromagnet. When you want to move it, just turn off the electromagnets and put it inside whichever recess you want. The number of the recess that holds the doorbell is displayed on an LCD display next to the door, inside, so you don't forget where you put it. When you invite guests over, tell them which recess holds the doorbell. Then move it after they've left so they can only bug you later if you've invited them again or they're determined enough to go through every recess looking for it.
