Why It Mattered

It adds Israel and the Eastern Mediterranean to the worldwide compendium with a production-story-rich badge that connects badgelife, CircuitPython, mesh ambitions, audio experiments, SAO expansion, and public hardware/firmware archives.

Hardware

CircuitPython and the hardware repository document an nRF52840 Cortex-M4 module, 2.9-inch GDEW029T5 e-paper display, LIS2DH12 accelerometer, GD25Q16C flash, VS1003 MP3/WMA codec, three Cherry MX keyboard switches, four WS2812B NeoPixels, SAO v1.0 connector, battery-voltage monitoring, vibrator pinout, and KiCad PCB files.

Software & Apps

The badge has CircuitPython board support and an MIT-licensed firmware repository whose installation path copies badge code to the badge drive and installs libraries with CircUp. The production writeup describes the original ambition for Python programmability, mesh networking, attendee interaction, and audio streaming.

Lore

Hackaday's 2019 production writeup places ARAMCON as a private tech event in Israel and preserves the behind-the-scenes story: prototype mistakes, reversed connectors, part substitutions, a clothespin programming jig, and a final mesh-networking demo that turned the room's badge LEDs yellow.

manufacturing workaround documented

Clothespin programming jig

The build story and Hackaday article call out a clothespin-based programming jig as part of the practical production workaround trail.

Compatibility: ARAMCON 2019 Badge

Source

production story partially realized

Mesh and audio streaming ambition

The production story documents planned mesh networking and audio streaming, with final event success framed around a room-scale mesh LED demo rather than complete audio broadcast behavior.

Operational history

Issues & Camp Impact

audio feature caveat note

The badge was designed with an MP3/WMA codec and audio-streaming ambition, but the public production story says the shipped result worked while falling short of the full audio plan.

The record distinguishes hardware capability and project ambition from the exact final attendee experience.

Confidence: source-backed but nuanced
Status: documented
Timeframe: ARAMCON 2019 production and event demo
Source note: Hackaday article and Uri Shaked production writeup.

image provenance upgrade note

The ARAMCON 2019 visual uses the CC BY-SA 4.0 `docs/intro.jpg` documentation photo from the official badge-docs repository.

The Israeli entry now has a rights-cleared original documentation photo with source URL, license, attribution, and processing notes while avoiding generated or placeholder imagery.

Confidence: repository license and exact documentation photo
Status: licensed original replacement applied
Timeframe: current catalogue build
Source note: ARAMCON badge-docs repository image file, README license badge, LICENSE file, and badge.gallery image policy.
