Space: the final frontier. These are the voyages of DCZia. Its continuing mission: to explore strange new ideas, to seek out new friends and knowledge, to boldly make, hack, and explore everything we can!

Originating around DEF CON 22, DCZia is a group organized around the concepts of teaching, learning, and creating badges / other electronic hardware. Most of us have loose ties to New Mexico, but now we live all over the US. DCZia welcomes both newcomers and experts alike. Proud holders of the DC DarkNet DEF CON 25 Black Badge!
