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.
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

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
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.
