DEFCON 18 Badge
The DEFCON 18 Badge was created for the 2010 edition of DEFCON, the largest and oldest continuously running hacker and computer security convention in the world. It features active electronics mounted on an artistically designed, aluminum substrate printed circuit board. [ continue ]
DEFCON 17 Badge
The DEFCON 17 Badge was created for the 2009 edition of DEFCON, the largest and oldest continuously running hacker and computer security convention in the world. The badge uses active electronics, features an artistic circuit board, and provides an open design to allow attendees to experiment with and modify the badge to their liking. The goal of this year’s design was to be elegant and stark, yet powerful. The badge is based around a Freescale MC56F8006 16-bit digital signal controller, Knowles Acoustics SPM0408LE5H amplified MEMS microphone, and Kingbright RGB LED. Its three operating states are determined solely by the sound level received by the microphone: [ continue ]
Circuit Board Artwork
The Circuit Board Artwork pieces were created during a series of experiments in precision circuit board fabrication using a T-Tech Quick Circuit 5000 Prototyping System. The original drawings were processed and routed onto single- or double-sided copper clad 0.062 inch FR4 with milling bits ranging in width from 0.010-inch to 0.031-inch. Sizes of the pieces vary from 1 inch by 4 inches up to 5 1/2 by 7 1/2 inches. Rights to all artwork are controlled by their respective owners. [ continue ]
