Tokyo · Japan · 2015
AVTOKYO's official 2015 badge page says the conference made an electrical badge for attendees, with an AT-MEGA328P-PU, eight 5mm LEDs, two push buttons, 16 MHz crystal, resistors, capacitors, IC socket, coin-cell holder and battery, public KiCad PCB design, and public Arduino program.
Lifecycle
The official badge page links an Arduino sketch with TimerOne LED scanning, two interrupt-driven buttons, menu modes, POV output, and a not-binary game path.
The official parts list centers the badge on an AT-MEGA328P-PU, eight 5mm LEDs, two push buttons, 16 MHz crystal, passives, socket, and coin-cell power.
The official badge page links a public PCB design repository that preserves KiCad project files, schematic, board layout, Gerbers, BOM, and manufacturing PDFs.
Operational history
The record preserves the original assembly warnings and avoids silently normalizing the battery spelling beyond the source text.
The Japanese entry remains source-backed and image-free rather than copying Google Sites imagery or repository artifacts without complete image provenance.
