Make a cool circuit necklace!

I made my necklace with a perfectly round piece of circuit board I found in a parking lot. It had a hole already punched through it, but you can drill a hole too.

You need:
Clear nail polish
Circuit Board
Leather cord
Barrel Clasp

Scissors

Step 1 Clean and Coat the Circuit Board

I first put some hand sanitizer on my circuit because I found it outside. Then take the nail polish and coat both sides. Allow to dry and coat again, until any rough parts are smooth and it is shiny.
