DerbyCon
The September 22-24, 2017 DerbyCon Legacy edition whose public conference metadata and first-hand maker writeup document a special electronic Legacy Black Badge award artifact.
Hyatt Regency Hotel, Louisville, Kentucky · United States · 2017
The DerbyCon 7.0 Legacy Black Badge was a special electronic black-badge award artifact made for DerbyCon 2017, using an Atmel XMEGA core, a large LED-heavy PCB, laser-cut acrylic, custom STL work, and first-hand published build notes.
Lifecycle
The project bill of materials names an Atmel ATxmega128A4U microcontroller as the badge's controller.
The project links a compiled `DerbyCon7BadgeFirmware.bin` file and describes custom C firmware upload as part of the build.
The build notes document custom PCB design plus laser-cut acrylic and 3D/2D files for the badge enclosure and presentation form.
The first-hand writeup describes DerbyCon's black badge as the event's lifetime-ticket equivalent and frames this build as the Legacy Black Badge artifact.
The Hackster materials list names 224 Adafruit 0805 LEDs, four 74HC595 shift registers, and sixteen 2N3904 transistors for the visual badge surface.
Operational history
The compendium records the artifact under DerbyCon while avoiding claims of general conference distribution or regular attendee-badge status.
The record remains image-free rather than copying Hackster project media, screenshots, OpenGraph images, generated art, or approximate badge artwork.
The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The record keeps controller, LED, fabrication, and firmware claims tied to the first-hand project page and avoids unsupported protocol, challenge, and source-release claims.
