I enjoy electronics, however I am not sure I would love the flow of electrons through my privates. I don't like being shocked, but I also realize that there is a space between sensation and shock. I am also a total perv so the idea of estim does have some odd appeal to me.
The other day I was pondering this. Have you ever tested a single cell such as an AAA, AA, C, or D with your tongue? If you don't know the old trick, it works like this. Lick the tip of your index finger and hold the cell with your other fingers so the positive terminal is facing you. Now touch the positive terminal to your tongue, and touch your wet finger to the negative terminal. You should feel a very slight tingling sensation on the tip of tour tongue if the battery is alive.
This is hardly a shock. This is hardly a tingle, but.. Is it enough to give you a little erotic sensation on your naughty bits? I built a little device to find out, and truthfully I am not sure. The good news is that it is fun to experiment and you probably have what you need to build one kicking around the house.
Here is what you will need to build a tingler of your own.
A wooden clothespin, the kind with the spring in the center.
Two shiny metal thumb tacks. The nice bright sliver ones.
Three short pieces of insulated hookup wire. If you use wire with a solid conductor you can coil it around a nail and give it scary "electric chair" look, but any insulated hook up wire will work.
Two regular 1.5V "AAA" cells.
Tape. Black tape is good, but pretty much any sticky tape will work.
A small piece of cardboard, about 1" square
Something to strip wire and cut tape and cardboard with.
Optional: A drill with a really small bit
Construction starts as follows:
Dissect the clothespin but pay attention as we will be putting it back together!
Cut 2 pieces of wire about 2" long and strip about 1/2" of the insulation from one end and about 1/4" from the other.
Wrap the end of the wire striped back 1/2" around the shaft of each of the thumbtacks. You will have two thumbtacks with a wire attached to each one.
locate the inside facing end of both of the wooden half's of the clothespin.
About 1/4" from then end that would clamp on the cloths, and centered on the wooden piece, stick a tack in, with the wire hanging off. The idea is that these tacks will touch when the clothespin is re-assembled. This is where the drill may help to drill pilot holes for the tacks.
Put the clothespin back together. The tacks should now touch when the spring has the pin closed.
Now for some taping.
Take one of your AAA cells and tape it to the outside of the clothespin so the + side is pointing at the top where the tack is. The tack is on the other side of the wood.
Take the other of your AAA cells and tape that so the - side is facing the top of the other wooden piece.
Cut a third piece of wire about 3" long and strip about 1/4" of wire from each end.
With a small piece of tape, tape the wire that is near the + end of the one battery to the + end of the battery next to it.
With a small piece of tape, tape the wire that is near the - end of the other battery to the - end of that battery.
Take your little piece of cardboard and put it between the thumb tacks so the tacks do not touch.
Now with the last piece of wire, run that between the + terminal of the one battery and the - terminal of the other battery down by the handle of the clothespin. hold these in place with small pieces of tape.
Now, run some tape around the entire cell on each side to firmly hold the wires in place. Do this on each cell.
Congratulations! Your tingler is done!
To use it, wet down the erotic area you wish to tingle (licking your finger and spreading it around is fine), and than clamp the tingler on your favorite erotic body part. The sensation should be right on the edge of what you can perceive. I was pretty sure I felt a little more of a tingle than just the coolness of the thumb tack heads. Not much mind you, but a very slight tingle.
When you are done having fun with the tingler be sure to put the little piece of cardboard back in place between the tack heads to keep it from shorting the battery out.
WARNING: If you short the battery out, the battery and the wires may get hot. You will also kill your battery.
WARNING: This uses uninterrupted DC which can be dangerous. With the 3V we are using here there is virtually no chance of your hurting yourself, but do not add more batteries. If you want a more serous sensation use a device that uses pulses.
If you build one of these let me know what you think. See if you can get a partner to do some testing with and do a blind test and see if the little tingle is the the electricity or just the sensation of the tack heads. I think it was the electricity but I could see what was going on so my head may be fooling with me.
