Do not proceed unless you KNOW what you're doing.

Seriously dude, extracting some tin is not worth your life or limbs. Learn how this stuff works before you seriously damage yourself.

I'm more concerned about that "Wall Wart" transformer overheating from prolonged excess load and starting a fire.

it does get hot pretty fast. any idea how i can keep it cool? i dont guess sitting a ziplock bag full of ice on top of it would be a too smart.

Place a resistor in series with the load to limit the current from the transformer.

A small light bulb (e.g. a 12 V panel lamp for a car) would be a better choice. However, I think there's a good chance that the wallwart has shorted (or an internal fuse blown, though it shouldn't get hot in that case) and that's why the setup isn't working any more.

To the OP, it would be a much better idea to do this with batteries (such as a couple of those 6V lantern batteries).

batteries wont last long enough. i got it working now.i had it hooked up backwards. i will try that light bulb thing. thanks for the help crew
