content: Hi, guys, I'm trying to create a device that is super small with the dimensions of 1x2 inches, which can shock (hurt) a person but not kill them. Do you guys happen to know a minimum estimation of voltage, current, microcolumns, and pulses that are necessary enough to shock (hurt) a person but not kill them?My initial guess is that voltage of 200v-250v and mili-amps of 3mA with the dimensions and pulses 100 per second can do the magic with the form factor im looking for 1x2 inches. But again I'm super new to building EE projects, so I would be really happy to hear different suggestions. PS: It would be really helpful if you can share some sources or links so I can understand further!

content: In other words you are attempting to create a weapon that will likely get you in prison for causing bodily harm if you use it and depending on the laws of your country you could land in trouble even for merely possessing it.FYI, even 3mA at 200V can kill already, depending on the health of the person, where it is applied, whether they smash their head against concrete when they fall, etc. Also you don't know whether the person doesn't have a heart problem, pacemaker, whether their skin is dry or wet (sweaty, for ex). Feeling lucky, punk? Playing Russian roulette with someone's health/life for your entertainment?There is no safe voltage/current that "can shock (hurt) a person but not kill them". Taser (the company) has well documented cases of people dying after being hit with one of their devices (not counting the cases where the victim smashed their head against a curb when hit and similar) and they have been sued many times over it too. There is a reason why their gadgets are described as "less-than-lethal" and not as "safe" - they could still kill even though in most cases they don't.Don't expect much help with such stupid and dangerous project here. Also, don't repost the same thing over and over, do you think you will get different answers than in your other thread already?

When I was 7 years old one of those radio shack 200-1 project kits had a shocker circuit in it. Device must be intrinsically safe, so frequency and impedance must be appropriate to limit current (i.e. nothing mains powered, i.e. nothing powered by anything more than a tiny battery, no capacitors, etc..)Generally the idea is to take a tiny high impedance transformer and drive it with a square wave from a battery.Always keep one hand in your pocket. Good practice.

content: here we go. look that kid is thrilled hes about to shock the heck out of his sister, and Dad approves heartily"If the batteries are fresh enough you may be able to feel the high voltage pulses by touching both probes at the same time! Happy zapping!"Brought to you by Radio Shack 1982Also remember to check out fly swatter zappers for an easy source of high voltage generation that will DEFINITELY hurt

Granted 30mA is the cut out current of an RCD to save your life, but things are rather more complicated than that as it's 30mA for a set amount of time with more exposure to lower currents also being lethal. It's really, really not a gadjet that one just makes unless one has a lot of money and some really good lawyers.Just get yourself a pizo thing out of a lighter and be happy with that!
