Stun Gun Schematic
I am looking for a stun gun schematic (non lethal and would leave no burns). <p>I've found a few online but I'm not sure about the reliabiltiy of the source. I'm guessing it's just a couple voltage doublers with probes. Any suggestions would be very helpful.

Re: Phone PA system
Ok, forget the addressing scheme for the moment, how would I make the other phones ring with an 80 VAC generator? I read somewhere that the 80 VAC must be applied only when the phone is on hook, if it is applied while off hook, phones will be damaged. Thanks

Re: telephone busy light is not right.....
Ok, I'm kinda a newbie.. I looked at that schematic. What is the symbol below R1, with the label 15V. Is that a power source? What should I do with the grounds? Thanks

Phone PA system
I'm looking for an in house pa system circuit that should use existing phone wiring. What I want to do is be able to switch from normal phone operation to pa mode and when I pick up a phone have all others ring, or be able to select which phone I want to ring. Thanks for any suggestions.
