AVTOKYO 2019 Cocktail Blinky Badge

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.

Why It Mattered

It extends the Japanese AVTOKYO lineage from the 2015 AVR attendee badge into the late-2010s soldering-village badge culture shared with CODE BLUE, while preserving the local AVTOKYO party-and-security identity in the badge artwork itself.

Hardware

The Hackster project covers two custom PCB badge designs across CODE BLUE and AVTOKYO, using custom PCBs, 5mm RGB LEDs, 1206 SMD LEDs, CR2032 coin-cell holders, CR2032 batteries, and soldering-iron assembly. The AVTOKYO 2019 badge was shaped like a Pina Colada cocktail glass, used transparent no-soldermask PCB regions, and became an electronic cocktail rendition when soldered with RGB flashing LEDs.

Software & Apps

No programmable firmware, serial interface, MCU behavior, or source repository is documented for the AVTOKYO 2019 badge in the recovered public sources. The verified behavior is a soldered LED blinky badge powered by a coin cell.

Lore

The official AVTOKYO 2019 event page listed a Hackerware.io hardware soldering village that invited beginners to solder all parts onto a badge, become soldering ninjas, and also get CODE BLUE 2019 badge repair support. Abhinav SP's writeup says many AVTOKYO cocktail badges ended up on Christmas trees.

Operational history

Issues & Camp Impact

firmware absence caveat note

The recovered sources describe a soldered RGB blinky badge, transparent PCB design, and coin-cell power, but do not document a programmable MCU, firmware, serial shell, repository, or CTF behavior for the AVTOKYO 2019 badge.

The dossier keeps the artifact as a beginner soldering-village blinky badge instead of inventing software behavior.

Confidence: source-backed but intentionally narrow
Status: documented
Timeframe: 2019 badge archive pass
Source note: Hackster.io blinky-badge writeup and AVTOKYO 2019 event page.

missing rights-cleared image note

No local AVTOKYO 2019 badge photo has been added because the recovered Hackster article images and AVTOKYO event images have not been paired with explicit reuse rights, attribution, and processing notes for catalogue publication.

The AVTOKYO 2019 entry remains source-backed and image-free rather than copying project or event photos without complete image provenance.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy, AVTOKYO 2019 event pages, and Hackster.io blinky-badge writeup.
