Country dossier
Worldwide badge coverage for Japan, grouped into seeded badges, event editions, add-ons, operational issues, resources, and evidence sources.
Seeded artifacts
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.
AVTOKYO 2019's hardware soldering village used a cocktail-glass-shaped blinky PCB badge designed around AVTOKYO's no drink, no hack motto, transparent non-masked PCB areas, RGB flashing LEDs, reverse-mounted LED experimentation, CR2032 coin-cell power, and beginner soldering participation.
CODE BLUE 2019's first hardware soldering village used a simple Halloween-themed blinky PCB badge, built around a custom PCB, RGB and 1206 LEDs, CR2032 coin-cell holder, CR2032 battery, transparent unmasked PCB smile, and normal or reverse LED soldering options.
Events
The Japanese AVTOKYO 2015 edition whose official badge page documents an electrical attendee badge, public PCB design, and public Arduino program.
The AVTOKYO 2019 edition at TK SHIBUYA, where the event programme listed Hackerware.io's hardware soldering village and Abhinav SP documented a cocktail-glass blinky PCB badge.
The Tokyo CODE BLUE 2019 edition held October 29-30, 2019, where the first CODE BLUE soldering village used a simple Halloween-themed blinky PCB badge.
Lifecycle
The AVTOKYO badge used a Pina Colada cocktail-glass shape with transparent non-masked PCB areas to celebrate the conference's no drink, no hack motto.
The CODE BLUE badge used a scary face with transparent unmasked PCB areas and visible tracks like veins, matching the blue/black conference color treatment.
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.
The badge became an electronic cocktail rendition after attendees soldered RGB flashing LEDs and coin-cell power onto the custom PCB.
The soldering village kept a silicon glue gun available to improve light diffusion, and the writeup says almost everyone opted to use it.
Attendees were encouraged to solder LEDs either normally or reverse-mounted; reverse mounting dispersed light better on both sides of the PCB.
AVTOKYO's event programme listed a Hackerware.io hardware soldering village where beginners could buy a kit at the booth and solder all parts onto the badge.
Operational history
The record preserves the original assembly warnings and avoids silently normalizing the battery spelling beyond the source text.
The dossier keeps the artifact as a beginner soldering-village blinky badge instead of inventing software behavior.
