This is an easy way to get volts from pennies card board and vinegar

Step 1: What You Need

-Pennies (preferably before 1982) 
-cardboard
-Vinegar
-Sand paper
-Duct tape
- Wier

Step 2: Step 1

Put all your pennies on a sticky surface and sand them down
Sanding the pennies down will release the zinc under the copper coating 

Step 3: Step 2

Cut out cardboard disks and soak them in vingar

Step 4: Step 3

Next stack the pennies and cardboard disks in the order of : penny,cardboard, penny, cardboard

Step 5: Step 4

Now You can put wire on both ends and duct tape it all up 

Step 6: Finished

Now it should look like this and if you did it right it should give off close to 3-5 volts

    Nice simple idea you've got. But I think you'll need fully copper pennies (1981 and earlier) alternating with sanded zinc pennies (1984 and later to be positive, since a few rare ones were copper in '82 or '83). So to clarify, your opening statement about 1982 pennies should mention both kinds. Pennies 1981 and earlier are solid and are not zinc with copper plating. Hope this helps make your project better! :)

    How long does it last?

    Interesting. How do you connect it to something to be powered?

    sorry on the the late reply
    depending on the amount of volts it gives off you could probably power a small flash light or something else that is small
    to do it you will need to hook the 2 end wires to the spring and mettle plate the battery is supposed to be touching

    sorry but I had to make another one that wasn't as big as my first one
    This one was only 5 -7 circuts
