I have a tens unit also that runs off a 9 volt, its stronger than similar ones I've tried out before, and yes when you bump it up to the high setting you Definetly feel it, its very strong. Yet tens units are sold all over and considered safe. I'd bring mine all over the place, parties, work, etc. I've probably shocked 500+ people with it over the past 10 years or so that I've had it. Quite a few people (including me) have put it on their chest, on maximum setting. And believe it or not, I've got many many women to put it on their chest as well *wink*.

I've never had a single bad experience. So if tens units are made safely, then I should be able to make a safe version of whatever I make.

I think people must be over-estimating what I'm trying to make. I'm not trying to make some super powered, way stronger than anything else, shock device. No. I'm basically just trying to make a simple device like a shock lighter. The only difference is rather than put in in a lighter, I'll put them into all sorts of other random objects. As far as the power output I'd like it to be just a little stronger than a regular shock lighter, but less than or equal to the shock strength of a tens unit.

And yes i do want it to be safe, but obviously with the number of tens units on the market, the power output by them is safe, so I'm trying to make a safe, and similar device also.

 

A Chinese guy sold millions of "tens" units on TV claiming they build muscles. He was charged by the government with fraud!
His tens unit zapped the person so their muscles twitched. A muscle that is simply twitched does nothing and does not get stronger. A muscle needs to work hard to get stronger.

I don't know if his zappers killed anybody.

Aren't you even concerned about the reactions of the people you zap? Some people react quickly, reflexively, and violently when shocked. First ones a freebie, if you're quick enough, but I don't have much of a sense of humor for such things. Really hate getting shocked.

 

Good point. If I was shocked that way, I just might deck the b*****d.

Well, I've never had a bad experience. Ever since I first discovered the shock lighter about 8 years ago, I used to always keep one in my pocket everywhere (as well as backups in the car since they break easily when people instinctively drop them). People ask me if I have a lighter all the time, and I'd be ready with it. I've shocked hundreds of people with them (not to mention all the other shock devices), and nobody has ever threatened a punch. Honestly I make more friends than enemies. Usually as soon as someone gets shocked they want me to come along and, shock all their friends. It ends up livening things up.

 

Hi Carl,

here is a circuit which operates at a stable frequency of 25.6KHz generated by a crystal oscillator of 3.2768MHz.

The voltage output is adjustable in a wide range.

Electric shocks are always dangerous. If somebody gets shocked using a heart beat electronic device the cables of which might catch on fire.

You might try building that circuit. Overvoltage protection is given by using 30V zener diodes across the power transistors to eliminate excessive output voltage caused by possible oscillations. (depending on PCB routing)

Additionally the output current is limited to ~27mA at 30V with the output pins shorted.

Try the circuit on yourself before you use it on others. Since the frequency is relatively high you might not feel a shock but suffer from high frequency burns.

I do not take any responibility for harmful applications.

To audioguru: Muscle stimulators were never intended to build up muscles. They have been designed to do what they are supposed to do - stimulating muscles. They are used for patients suffering from e.g. a traffic accident having had an arm or a leg bandaged for a long time period.

I know what a tens unit is for.
But the TV ads for the muscle twitchers showed fat people sitting on their couch getting zapped then showed them later with strong toned muscles.
A bunch of lies. Millions of the useless things were sold.

Hi audioguru,

I suppose "tens" is another expression for "LIMS" (Low Impact Muscle Stimulator) as I prefer to call the device.

I also wonder why such advertising (containing misleading information) is allowed to broadcast in Canada, which is impossible in Germany because the promised and advertised features of any technical device must be proved before advertisement on TV.

In case a product doesn't do what it is supposed to do the advertiser is well advised to commit suicide before a judge of law gets on him.

The German term for that is "Verbraucherschutz".

Regards

Hans
