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
Do you have a picture of this with a multimeter?
