This thread http://www.mattersofsize.com/forum/showthread.php?s=&threadid=3101 explains the Blakoe ring.

The image below is my cheapy version of it.

I used a piece of copper tubing and a rolled up piece of zinc I had recoverd from a cheap carbon-zinc (not Alkaline) AA battery.

Repost of my earlier material:
I found a convenient source of zinc metal. Cheap carbon-zinc batteries. Not alkaline, they have steel casings. But the cheapest carbon-zinc cells have zinc casings.

You'll have to cut it apart and clean it up. Best to use a new cell, because otherwise the inside surface is pretty corroded and you'll probably want to sand all that stuff off.

I just opened up a AA cell which was not new but not dead either. I did have to clean the inner surface pretty well with sand paper.

The zinc case is pretty soft. It usually has a paper or cardboard outer layer. You can cut the zinc pretty easily. I cut mine apart with an Xacto knife. Once I got it rolled out in a sheet, I was able to sand it up, and then cut it to whatever size I needed with a plain old scissors.

In sheet form you can then shape it how you wish, but I rolled it around a screwdriver to make a tube like shape.

Remember though, use cheap carbon-zinc cells only. Alkaline have steel shells. NiCad or NiMH have (probably) nickel shells, etc.

So using the above zinc section (about 1" x 1/8") and a similar section of copper tubing, I threaded some cut up rubber bands through them, and put it around my unit. I also measured 0.7 volts.

Since I had the copper tubing as scrap, and a carbon-zinc cell already, and, of course some rubber bands, total cost to me was $0.00.

Cool. There is only one thing, the zinc you are using is not 99.95 pure zinc inhibitor rod. That is unsafe to use that kind of zinc. The design is cool, a little midevil, lol, but its cool, is it compfortable. I just would not use that zinc casue its not really safe for humans.

I know that you know what ure doing, but whats the point of the copper, if rubber is an insulator, how is it supposed to make electricity with the zinc?

hey, is there any way to do some mineral.lab test etc to see if somethings zinc. I have an Oakaido battery, very cheap battery, doesn't say it's alkaline, in fact doesn't say anything about what kind of battery it is. when cut open, there was one piece of , what seemed to be graphite, lead or the stuff used in pencils, along with a ton of other crud I scooped out.

how is the zinc unsafe?

The zinc that I am using is safe. The zinc that Bob is using is not 99.95 pure zinc rod.

It makes voltage becasue of the copper and the zinc connecting with the skin. The latex tubing has nothing to do with it.

The zinc in batteries starts out as better than 99.99% pure zinc. Battery manufacturers might add some fractional percentage of other metals to produce their proprietary zinc alloys. However because of enviromental restrictions, that won't include harmful metals such as lead, cadmium, or mercury. Some alloy metals might include copper and/or titanium.

Obviously none of these metals will inhibit the galvanic properties of the zinc (which would foul up the battery operation.)

The zinc content is still on the order of 99%.

Well your the engineer, I just would not want to put anything from a battery near my penis.

heh, I'm not a materials engineer, and the alloys are proprietary anyhow, so I'm not certain what is in them.

If anyone is afraid of using battery zinc for fear of it containing toxic metals, they should not use it.

Here's a little modification I made to the above device.

I decided to go for current flow in addition to voltage.

The diagram shows a 470,000 oHydromax resistor. I actually used a 560,000 oHydromax resistor. Measured voltage was 0.41 volts.

This means there is a current of about 0.7 microamps (or 700 nanoamps.)

100% zinc (if you could get it) would be useless. Zinc is a very crumbly metal and it would simply fall apart if not either ionically bonded to another metal as in galvanising or combined as in an alloy. boat anodes are about 98% and easily good enough and I reckon a cut down galvanised nail would work ok. KISS ... Keep It Simple Stupid!
