Badges
Japanese ATmega328P LED attendee badge
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.
Japanese cocktail-glass soldering-village PCB badge
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.
