Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The second badge is documented around a VoCore/RT5350F module running OpenWRT with Wi-Fi, two Ethernet ports, USB host/storage goals, and heatsink work.
Badge context
Primary Hackaday.io project source for the dual-badge concept, PSoC4/ESP8266/WS2812B blinky badge, VoCore/OpenWRT RT5350F network badge, and production timeline.
Conference archive source for the May 23-24, 2015 Sheraton Gateway LAX, Los Angeles LayerOne event context.
Hackaday coverage from the LayerOne 2015 Hardware Hacking Village corroborating that there were two badges and that each came with different hacking paths.
Technical source for PSoC routines, UDP-driven RGB output, CR123A battery behavior, level shifting, reverse-polarity protection, ESP8266 caveats, OpenWRT/VoCore setup, USB storage, LuCI, sysupgrade, and telnet/SSH paths.
Official HHV page identifying the 2015 Electronic Badge and linking CharlieX's Hackaday.io build details for both badges.
Project log documenting kits, speaker and staff badges, LED badge assembly, TM-220A pick-and-place work, chainable LED boards, and late production workflow.
