Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The guide points builders to Hardware Hacking Village equipment and personnel, and the event page says attendees could put their badge together there for the duration of the conference.
Badge context
Official PDF guide for the 555 timer, resistors, LED, capacitor, photoresistor, battery holder, wire, soldering steps, battery test, light-reactive blinking behavior, and lanyard/blank-board context.
Official source for March 4-6, 2016 Raleigh dates, Hilton North Raleigh / Midtown venue, admission price, badge-kit inclusion, Hardware Hacking Village context, Arduino-compatible donation hardware, and links to the schematic image and instruction manual.
Official linked partial schematic image used only as evidence; it is not republished because no reusable image license or explicit permission basis was recovered.
Source trail
Primary event source for the March 4-6, 2016 Raleigh edition, admission-included electronic kit badge, Hardware Hacking Village assembly support, Arduino-compatible donation hardware, and official badge-guide links.
Primary assembly source for the CarolinaCon 12 badge; the PDF title uses '2012' while the hosting page, URL, and context identify it as the CarolinaCon 12 / 2016 badge guide.
Official partial schematic evidence linked from the event page; cited for source traceability and not reused as a local image because no reusable media rights were found.
