The easiest way is to use my computers sound card and a WaveGen software to create interesting waves, and connect its outlet to a 40W (or so) amplifier
That's an interesting idea. If it could be amplified enough, which is the key.

The "muscle stimulant" "machine" I have is made by Bodi-Tek. It's a unit I picked up in HongKong in '95, but I have seen for sale in the USA recently by a mail oder company called Damak. As a techy-type, I've looked at it's output (unterminated) on an o'scope. It outputs spikes (positive or negative, depending on a switch on the leads) at a 1Khz rate, in a with a variable on-off time, but is always a duty cycle of 50%. The amplitude that I can begin to feel these pulses is over 100V Pk. The max it goes to is 370V Pk, which is cock-numbing (and kinda painful until things start going numb).
>how could it be, that those small Tens units have enough power like PES Electro sells?
My unit runs on 6VDC (4 x 1.5V batteries). I run it with an AC adapter (117V 60Hz 100mA 12 W Input, 6VDC 500mA (max) Output).
I've never disassembled it, but I've assumed it either has a large output amplifier, or a step-up transformer at it's output (or both).
>Since I'm located in Europe, I want to do my own cheap configuration instead of purchasing those expensive little toys from the US. Can anybody help me out, and give me a configuration that really works?
I've wanted to bump up the output for pain purposes, but haven't run it through another amplifier yet. But I have also tried...
A Commercial Unit that I picked up from a used Electronic Shop. It's a WaveTek 20 Mhz Pulse/Function Generator Model 145. It has a veriable frequency from under .01Hz to 20 Mhz. I get very painful results under 500Hz, and feel vey little about 4Khz. It's output attenuation (on front panel, not measured) is listed in db. It also has a DC Offset feature, which is what causes most of the hurt.
Straight DC hurts, with as little as 12 volts. If anyone doubts that, stick a 9-volt battery on your tongue and feel the tingle. Put a 12-volt (NOT a car one, it'll knock your brain for a loop) to your tongue, and you'll really wish you hadn't.
The 145, has outputs of DC, sine waves, square waves (+pk, -pk, pk-pk), triangular and pulses. Pulses feel best, but sine and triangular are close behind. This unit is way-overkill as it has many features that do not apply to sane cbt.
I have not recieved electric burns from the Bodi-tek unit, but I have with the 145. Electric Burns are *slow* to heal, and are prone to infection (due to the slow healling rate). I have always known when damage was occurring when I felt a sharp stinging sensation, rather than a varying pulse sensation.
I don't recomend anyone buying the US$50 acrylic cock rings, unless you have money to burn. It's vey easy to make very similar rings much less expensively, but this post has gotten way to long.
---------------------------
Try adding a manins transformer 240V --> 6V UK or 110V ---> 3V EU
reversed so the Volts are increased and the amps are dropped. UK price about £2 from Maplins Electronics or Tandy. When conected to a personel casstet player this works very well so should work from a PC sound card. The volume control also becomes an intensity control. If connected to a personal stereo you have a small mobile unit.
: Hi All,
: I've just got into self-electro stimulation/torture. I've read a lot of posts about how to build electro stimulation toys, electrodes, etc. The easiest way is to use my computers sound card and a WaveGen software to create interesting waves, and connect its outlet to a 40W (or so) amplifier. Well, as an electro techician, I tried this configuration, and I even built a signal generator, which creates various sounds as well. I connected to my amp, and I connected the loudspeaker outlet to my balls, cock, etc, with bare copper wires. I also used olive oil as lubrication as it was recommended in several posts.
: But, nothing happened. I could not feel anithing. not even a tickling at maximum power setting...(?) When I measured the volts when it was attached to my balls, it indicated only 5 volts or so.
: So, I'm totally embarassed. Maybe I screwed up something, or there is not enough power in my amplifier. (But if this is the case, how could it be, that those small Tens units have enough power like PES Electro sells?) Since I'm located in Europe, I want to do my own cheap configuration instead of purchasing those expensive little toys from the US.
------------------------ You have to download a program named WavGen (I do not have a URL). The program produces sine or square waves. Two waves can even be combined such as 300 cps (10%) and 5 cps (85%) waves. Square waves have a period of zero power which lets the muscles relax between peaks of stimulation. WavGen can produce a 1 second wave and then play it back repeatedly.
Some speakers have a headphone jack that you can plug into. Use a cable with a mini-jack on one end and two clips on the other (get at Radio Shack).
The real problem is that human skin is not a good conductor so you need to have two good electrodes to clip to. Two ways to improve the performance of an electrode are to increase conductivity (use olive oil, salt water, KY and salt, etc.) and to increase the contact surface (clipping directly to the skin gives a very small contact area). You might consider doing both; using KY and salt with a number of turns of copper wire around the cockhead and likewise with another piece of wire around the ballsack (which has the added advantage of snuggly trapping the balls).
I, of course, do not recommend this kind of activity.
: Pete,
: Would you explain in a little more detail, for those of us who aren't in the electro-tech know, how to use a soundcard to produce stimulating waves? Do you plug the power speaker into the card and then stripped wires from the outputs to the spots you want to stimulate? I've tried DC, and it's not variable enough and pretty unpleasant, and I'd like to try something that can move a little more gradually from stimulation to pain - never losing the pleasure part.
: Thanks, guys.
------------------------- If the semen is yours, there should be no problem with you consuming it. Not my bag though.
I've also never been able to get into the urethra sounding either. I know that a lot of people do it and don't seem to have complications. Not to bring you down, but there are some very painful ramifications if something does go wrong. There is a layer of connective tissue just below your skin that is continuous over your cock and scrotum. A urethral tear would not only be painful initially, but may direct urine out into this potential space instead of out your penis. I don't think that I need to explain your unhappiness as a full bladder empties into your scrotum. I've seen a picture, it aint pretty. If you are gung-ho about trying this for your women, I would try to find as much information about the proper technique to use, as you said that they are not very experienced.
There is a muscle called the trigonal muscle in your bladder that contracts to close the proximal end of the urethra during ejaculation. In some men this does not work correctly and they have what is called retroejaculation. Some or all of their semen will empty into their bladder instead of erupting in a manly spurt. If you could create enough back pressure by binding your penis to overpower this muscle and the semen would enter your bladder. I would imagine that this would be fairly painful. Where to bind probably depends on your desired effect. If you bind far out on your penis, I would bet that it would be more painful than toward the base as the pressure would be exerted along the length of your entire urethra. If you aim is the escape of a minimum of ejaculate, then toward the base would be best. Anywhere outside of the prostate should work and since that is inside your body, anywhere along the penis would be effective. That is, assuming that the pressure from your ejaculation would be enough to over come the contraction of that muscle.
Good luck and be safe
remember you may be the Lizard King, but your penis isn't your tail.

I have bound the end of my penis very tightly with thin string. I thought I would start bleeding it was bound so tight when I was fully aroused. To my delight the whole affair turned me on so much I came. As I was about to explode I kept wondering where the cum would go to. Would the uretha expand to accomadate it or would it be forced some where else. To my amazement the pressure was so great that it forced the fluid out the end of my cock anyway. Although the feeling was very intense there was no pain associated with this event. After the intense bursts were finished I removed the string to release the cum that remained.
