A Defcon badge unlike anything you have ever seen

It's sleek, stylish, programmable, and made out of metal

More than a fanzy gizmo, the defcon badge is a powerful computing device, just waiting to be hacked. This is the fifth year that Grand has designed an electronic badge for the event. It's a labor of love that takes him months to complete. Grand says he wants to make something that's powerful and exciting to hack. Pictured here is a coveted black "Uber" badge, reserved for winners of the annual Defcon badge-hacking contest. Its owner gets free Defcon admission for life.
