Building A ROP/BZ outa pennies

The amount of copper/zinc is not really an issue, but the surface area in contact is to some degree. If you had a copper block the size of a building and a similar zinc block, the voltage (potential difference) between them is the same as 2 fragments of metal connected. current=voltage/resistance. your volatage is a fixed value and your resistance between 2 surfaces of the same area is fixed so current is the same. i.e. if your massive blocks of copper and zinc had copper and zinc pennies welded to them which were in contact with your sac then the current is the exact same as if there were just a copper and zinc penny alone. In a household battery with a single cell the potential difference is 1.5V if you connect a device to it which draws a certain current it does so because it is of a fixed resistance. If you have a tiny watch battery and a big lamp battery both at 1.5V they both will draw the same current, however the small battery will be wasted first. In our case the current involved is so tiny that the zinc degredation is extremely slow. If you smear your sac with conductive gel the zinc will degrade quicker and the current will increase but the voltage is still the same. Those small 9V batteries have 6 small cells linked up to give 6x1.5=9V. Has anybody tried to connect up a 9V battery to their sac? essentially it should be the same as a few copper and zinc rods in place.

Again current=voltage/resistance. Your sac has a huge resistance so the current drawn is tiny. If you have a material made into a rod its resistance is proportional to the cross section area. So a thick copper rod has low resistance and a narrow copper wire has relatively high resistance. just like a narrow pipe is more resistant to water flow. So if you have copper and zinc with a large surface area then it has a better connection to the highly resistant skin (I am not 100% on that, maybe the copper and zinc area effect is not really an issue as the skin resistance is so high compared to a copper wire as thin as a hair). Also why ems machines have large pads to even out the flow, anybody with an ems has probably gotten a shock when it is not fully in contact.

If you have not sanded off every scrap of copper from the penny then the zinc will not work properly.

I have seen some commercial zinger rings with tiny bit of copper and zinc, has anybody used these with success?

Hmm, so are you saying we can make a ROP out of Just pennies?
If it is Zinc galvanized in copper then it would, when put against your acidic balls generate volatage right?

Physics was a long time ago in my education, but I don't see how this works.

The way I see it, there are two ways you can up the current:

Increase the voltage If we increase the voltage, we increase the energy of the charges. Each charge will then flow faster, so the current will increase. {A fast moving river carries more water per hour than a slow one of the same size}. So current must be proportional to voltage.

Increase the number of charges flowing. The more charges that flow, the bigger the current will be.{A wide river carries more water per hour than an equally fast flowing but narrower one}. The way to increase the number of charges is to decrease the resistance. So the current must be proportional to 1/(resistance). We say its inversely proportional to the resistance.

Now I fully admit that I'm no expert in physics, but can someone explain to me how, given the definition of OHydromax's Law you can increase the current without affecting the other variables?

In this I assume:

Resistance does not change.
Voltage does not change.

So given that I = V / R and in this example V and R are constant, nothing has changed, theoretically. I.e. the current has not increased.

Good skin contact is an issue however, pennies could be hammered into a shape giving a convex curve on one side (the ball side) and a convex curve on the other.

This could then be attached to any type of rod you like, so that you can use your left over 3/8" tubing.


I had a quick look online, but didn't see anything on a relationship between mass and current.

Can anyone explain?

Thought I'd add:

I don't want a penny zinger. Swm's got it with the dirtiness of them, I wouldn't dare.

Apparently they are made from good metal though.

I don't want people thinking my above post is an attack of Supra or the ROP, but I would like someone who actually knows their stuff (like Supra's dad maybe) to put me straight.

All I've got is crap higher physics and google. :D

Cheers!

Yes E=I X R E is voltage I is amperage or current and r is resistance.OHydromaxs law the Current will drop with more resistance If you string pennies together there is resistance between each penny then the resistance of your skin=no current.If I remember by electrical training amperage is "the shit" you can get hit with three hundred volts but if the current is low your ok,put some current in there and you're electrocuted.the current in Supras ROP is what gives the benefits.

That makes sense. It is very difficult to make a really good electrical contact with metal.

I knew it was simple!

Yep I think it can be made from pennies. It is supposed to be pure metal. I am not sure if a new penny and sanded new penny will work though as the copper penny is in direct contact with zinc and it my be "neutralised". Ships use zinc as an expendable metal strapped to the metal hull, the zinc is the first thing to be attacked by corroision so it is a sacraficial metal. You can do a search for galvanic erosion for more on this.

I also want to say my previous post is not an attack of Supra or the ROP. I would take the ROP over a penny ROP anyday, more comfy and the pennies are very hard to sand down to TOTALLY remove any copper which I think is very important as I stated. Supra's ROP has a good contact area whereas pennies are hard to keep in contact especially if the ring starts to roll about.


"Now I fully admit that I'm no expert in physics, but can someone explain to me how, given the definition of OHydromax's Law you can increase the current without affecting the other variables? "
You can't! the voltage is fixed but the resistance is not. If you put conductive gel (used on EMS machines and available where they are sold) on your sac it makes you more conductive and therefore you have less resistance to current flowing. since resistance is lowered and I=V/R then the current flowing increases. I think better contact should help too but I am not certain. Also the closer the 2 metals are to each other the less the resistance (since it only has to pass through a small bit of skin) and more current will flow, however this means current is passing through only a small area so it may actually be less effective.

I tested out the 9V battery and got a uncomfortable zinging. this is probably because the terminals are so close together so lots of current flowed through the small bit of skin as I mentioned. If you connect a 9V battery to the ROP metals you should get a supercharged ROP. Also with good contact and more space between the terminals it shouldnt cause a sharp zinging effect. The zinc and copper should be connected to the correct +/- terminals on the battery and I am not sure which is which.

Could you not use an Acid to remove the Copper layer to expose the zinc?

Maybe but it may take a while, hydochloric is good for cleaning copper but don't know if it erodes it much. The best way would be by electrolisis using the copper to plate a nail with copper, that way all the copper should go from the coin and the zinc layer is pefectly intact. You need copper sulphate for this and a battery.
For the cost and effort involved you are better getting a zinc rod!

Hmm i take it you could sand it down, but this would probably take ages.

As far as I know todays pennies contain very little copper. They are mostly zinc and aluminum. That is unless your coin collection contains "wheaties". Wheat back pennies contained a lot more copper but they stopped making them back in the 1950's. Besides, exposure to aluminum is supposed to contribute to brain disorders like Alzheimers, thats why they stopped making cooking pots out of aluminum. You need to be careful about the sources and purity of the metals you use since like someone above said most metals today are alloys. Many of which can contains high amounts of lead and aluminum, two metals proven to have bad effects on the bodies bio-chemical reactions with extended exposure.

Ok! I think I have it! It's so easy!

Zinc X Voltage/Current + ball sack resistance{shaved ballsack, that is} - length of penis+ Copper X 50% / OHydromaxs + number of pennies - current = uhhHydromaxm....

Ok. I guess I don't have it.

BUY THE ROP!

Kong you funny MO Fo! Thats y I love you so much!

The one benefit I would see for using the pennies would be surface area contact, being that they're flat, as opposed to the rods, which are cylindrical.

The whole germ thing on pennies is not really an issue; nothing that a little alcohol wouldn't solve. Any germs are on the surface and would've live very long anyway. It's not like any germs actually get into the metal and stay there.

I also don't believe the mass of the two metals matter, although, I think we need someone who has expertise in this area to explain this fully.

The ROP is definitely a much more convenient solution.
