Simple electric shock device? (58)

If it were that simple then everyone would be doing it. . Firstly your MP3 player won't push out enough energy for you to feel anything. It is possible to use computer driven amplifiers together with cobbled together transformers to generate the higher voltages needed (the term is 'stereo stimming' and the circuit is a 'phaser'), but it is far from safe, as your PC is connected to the mains and the results are highly variable. It's not something I would recommend to a beginner. Secondly the ABox and its more powerful brother the Series 2 uses quite sophisticated processing methods to manipulate the sound input to a produce a level and a set of frequencies you can feel - the human bodies response to audio stimulus is highly variable hence the more specialised audio files available on the site.

Hope this helps but if you want to know more, please drop me a line.

No, but it's sounds great. Be interesting to try it out with my CD collection. The Orb at one end of the scale, with Motorhead on the other? Then again for my last sub putting up with my taste in music was torture enough!

First the warnings. Electricity Kills. The heart is most sensitive to 50Hz AC, i.e our domestic mains. Just one of the many unfortunate coincidences in life. A current as little 40 milliamps can cause the heart to go into fibillation. This is because the heart is controlled by tiny electrical impulses, and if we come along and introduce our jolt, we overpower the 'controls' and the heart muscles go into an uncontrolled spasm like a fit, which results in no blood been pumped out. Seriously Bad news. You'll all of heard of defibillators, this is where a machine delivers a controlled pulse that stops the spasm allowing either the heart to start beating normally instantanously, or to allow external CPR to start it. A strong thump to the chest can also defibillate. Also the 40mA (average) level is why RCDs are designed to work at 30mA. Quite seriously, even if you never intend shocking your partner, learn basic CPR with your local St John Ambulance or Red Cross. You never know when you might need it. If someone drops in front of you with a 'heart attack' if you start CPR within a minute they have a 90% chance of survival, 3 minutes and it's down to 70%. Wait over 4 minutes and it's less than 20% with poor long term prospects in real life, this been not in perfect hospital conditions. What does 40milliamps mean? (don't complain all who do know - too many don't, so let them learn) In pratical terms 40mA is about the current that a small PP3 battery put on your tongue can provide, i.e a very small amount. Your kettle uses from 8000 to 13000ma. Even putting your finger on the other end of a normal light bulb which the other terminal is connected to the mains still can give you 200mA so never think of using a bulb as a 'dropper resistance' This is what about 60 years ago people used to do to run lower voltage devices off the mains. When 'applied' to the human body, 40mA equates to a voltage of just 40 volts applied between one hand and the other. Electricity likes to flow through low resistance paths. the blood containing iron amongst other things making it a good conductor of electricity so as soon as current enters the body if it can flow into the blood i.e a vein or artery it can pass easily to the heart, with the other hand as the outlet, you can see how a shock from hand to hand passes straight though the heart. BUT the same happens with a hand to foot connection. the current still goes through the heart on the way to the foot. Thats why you only need to put one hand in the toaster to shock your heart. From this you can see why you must ensure that electrodes are used in pairs and close to each other so the current flows in preference between the penis or pussy or whatever instead of through the heart. Also current of as little as 20 mA applied to a muscle like the arm muscle can cause you to grip something so powerfully not even charles atlas could break your grip. Bad news if its a live cut lawnmower cable. Next topic. Long term use of the old fashioned shockers and converted door bells etc etc is bad for the skin and tissue because these devices give only a chopped DC and not a true AC shock. What happens is that when current flows in the same direction, even when it switches on and off, through any system of electrode and tissue, you damage and possible get permnament scarring from what is actually electrolysis, remember the experiments at school making gas from electrodes in salt water? so always use a true alternating current source. In a similar vein. choice of electrodes. NEVER use lead or aluminum as a cheap electrode, even with AC you still get some migration of the metal into your tissue and lead and aluminum cause long term brain damage. use the best quality copper or stainless steel you can get. Thats why the E stim range are so expensive, the metal used is top quality with little dangerous impurities. Using a good quality conductive gel is important as it reduces damage from prolonged use and provides a more consistent sensation. I used to use aluminum foil as a teenager, thats why I can't write short replies :P. Problems. your skin varies in conductivity from as much as 20,000ohms when you start with dry skin to as little as 600ohms when sweaty and under duress of shock. Thats why it can feel good one minute and painfull another as the resistance changes changing the current flow. As a rule of thumb, if you stop feeling any sensation, it could be that you have maxed out, the current is till flowing but you can't feel it. Like any sensation you become accustomed to shock, better to change site or rest every minute for a while to maintain sensivity for the same current flow. Long term problems. too much current will eventually burn your nerve endings meaning you need more current to feel the same shock. Possiblity of incontinence i.e peeing yourself if you shock to much around the uretha. there is also a possiblity, but I'm still researching this, of cancer been triggered by long term use, I'm still here after nearly 30 years but who knows...we do know that electricity applied directly to DNA can cause damage to the sequences just as radiation does.

Audio:- I experimented with this sometime ago. Using an audio power amp, I tried general music but found that usually it was rubbish because of the mis of frequencies. So I used a signal generator, sinewave. any frequency from 1Hz upto about 500Hz works. The lower end giving a lovely vibrator like, internal feeling and above 50Hz a more tingly feeling. higher than 500Hz and you become less sensitive to shock. BUT the risk of skin damage remains. As music goes upto 20000Hz you can see most of it is wasted. It's a question of experimenting, the TENS type units more or less provide the same range of frequency and level control but more safely and conviently but for a small cost. Unless you understand about designing electronic circuits I'd stick with TENS. if all our cocks fall off in 10 years time we can mount a class action against the manufacturers Um lastly, I think. Using camera flash circuits, nice idea but no. The actual voltage is very high albeit very short duration. More chance of heart problems for less thrill. Very high voltages can spread across the body like spunk across your belly. less controllable. I'd be interested in what safety tests have been done on the dog control collars. as human appliances are often tested on animals, are dog appliances tested on humans? roll up ofr volunteers Thats al folks, I've finished (for the time)

(My background is as an ex electrical engineer, when I had to learn about electric shock, its affect on the body and CPR and as a one time ambulance driver)

Because,

1. putting instructions for making electric shock devices up online, especially in the context of BDSM (where the strong implication is that they'll be used on people!) is probably illegal.

2. if you knew enough electronics to make one, then you'd understand when and where it is safe to use one.

3. it's pretty easy to find out. google is your friend.

A couple of pointers: * Most electric fly swats are worthless.

* Not all electric fly swats are the same - read: some are pretty dangerous as they pump in more energy than is allowed by the regulations. How do they get away with this? They have the triple-grill system: triple-grill = dangerous.

* The one fly zapper which is relatively safe, and fun, is the Executioner.

* Nobody uses cattle prods with all the batteries in.

* Oh, and you know those electric-shock pens and other games, have you ever wondered how they work...

Just thought I'd highlight this for a bit more clarity:

********** DON'T DO THIS. ***********

Certainly mucking about with off camera strobes can, and has, killed. The capacitors in it can burn clean through a finger, let alone cause fibrilation.

I don' know if it's the same for little disposable jobbies, but with that much potential power, I wouldn't think it worth the chance.

- Scurrilous

If you don't put all the batteries in a cattle prod - it doesnt work at all.

The general level of so called knowledge here is more stunning and yet at the same time scarily worrying.
