Hey folks - Question. I'm working on a secret door disguised as a bookcase and I'm looking for some help from a curious and knowledgeable electrical engineer about a clever way to make the lock open. The desired effect is for the opener to touch two brass busts on the bookshelf simultaneously and the deadbolt will unlock and the bookshelf/door will open. I'm wondering if these two concepts can be combined: 1. A stick that shows that the human body is a conductor (right word?). http://www.stevespanglerscience.com/lab/experiments/human-circuit 2. A new type of deadbolt that (if you have the bluetooth fob) opens by touching the deadbolt rose. https://www.amazon.com/Kwikset-925-...8&qid=1385874945&sr=8-2&keywords=kwikset+kevo Is it possible to combine them or will the power required to work the lock shock/kill the person who acts to complete the circuit? My plan was to cut the wire that connects the deadbolt rose to the main servo and then run that to both busts and then run another wire from either bust directly to the deadbolt rose to simulate the touching. Then, when somebody touches both busts, the circuit will be complete and the lock will open? Is this a good or bad idea? Is there a simpler method? Don't say use a key. ;) Thanks!
