Since I haven't found a nice instructable on electroplating, I am now making one.
Warning! This is my first instructable!
What you will need:
1-1.5 v power source (old batteries preferred)
some kind of battery holder with alligator clips
small, non-conductive, disposable container (plastic or glass, the small yogurt containers are great)
a weak acid (vinegar: acetic acid, or lemon/lime juice: citric acid)
two or more pennies
quarters, nickles and dimes (almost any hardware you want platted)
time (at least 1.5 hours...I think, 3 is better)
plastic wrap (Saran Wrap)
here is all the stuff I used, the 3000 sq ft platic wrap gets a picture of its own.
Step 1: Fill your container with the acid
Remove the quarter and fill the acid past the line. If you don't have enough acid, you can add water and dilute it, but do not go past 50% acid (since vinegar and juice is already diluted). I had only half the lime juice I need so I just added more water until the surface was past the fill line.
