I've been looking around the interwebs for the past few days looking for a cheap and easy way to make a capacitive stylus for my Droid 2. Most of the ones I've seen require either conductive foam or anti-static packaging. I had some anti-static packaging laying around and decided to try it. Barely worked at all. And I don't have any conductive foam. So my search continued, until I read that you can use the negative terminal on a AAA battery. That got me thinking. Why can't I make a bioelectrically-powered stylus with only the things I have on my desk?
Things you will need:
*0.7mm plastic mechanical pencil (I used a BIC, remove the lead)
*one small metal paper clip (cannot be plastic coated)
*one silver thumbtack (the brass ones will probably work too, but I only had silver ones)
*needle nose pliers
Step 1: Step One: The Bending
Unfold your paper clip all the way. Using your needle nose pliers, wrap one end around the very tip of the pliers once or twice, until it holds the shape. Then bend the rest of the paper clip back perpendicular to the loop you just made. Insert your thumbtack into the small loop.
