10 DIY Projects for Tech Nerds

Don't hide your inner geek. Let your freak flag fly by making and then wearing jewelry salvaged from old electronics. Printed circuit boards (PCB) in particular are great for mixing and matching bits of components for unbeatably nerdy necklaces, bracelets, charms and more.

You can find PCB in all sorts of electronics. If you have an obsolete computer, for example, you can remove the motherboard, which is a mother lode of PCB for a major jewelry project.

After you find your PCB, you'll need to identify the parts you want to use and then cut them to size. This stuff is tough, so you need a saw (perhaps a hack saw) and a vise, miter box or other way to secure the PCB so it doesn't shift while you cut it. A dust mask, eye protection and gloves are NOT.

Once you've cut your pieces, you can drill holes for bracelet links or necklace fasteners, and then connect various pieces until your artistic muse is sated. File to remove sharp edges, and coat prickly parts (or just the whole piece) with clear epoxy to make your art more comfortable on the skin.
