Notes
Original 2160x2160 RGBA upstream raster render downloaded from the public Ekoparty_Badge_2025 repository and published as an optimized WebP delivery asset from the upstream PNG without synthetic or placeholder content. The repository top-level LICENSE is GPL-3.0; this is an official repository render rather than a documentary field photo. The published badge.gallery delivery file is an optimized WebP generated from the rights-cleared local derivative/source with metadata stripped, WebP quality 82, and a maximum side cap of 1600 pixels when the source is larger; upstream source URL, license, and attribution remain unchanged.

Why It Mattered

It shows the South American badge scene maturing into open, expressive, conference-specific hardware with public firmware and hardware material rather than only scarce attendee swag.

Hardware

The official badge page identifies the badge as artistic, sonic, and customizable. The public repository documents an RP2040, PCM5100 I2S DAC, TPA6138 headphone amplifier, TPA2028 speaker amplifier, rechargeable USB-C battery, 10 NeoPixels, and four resistive touch sensors integrated into the PCB.

Software & Apps

The repository documents Arduino/RP2040 build paths, AMY audio library usage, UF2 flashing, default Dr. Dre sample firmware, an extra synth-drum firmware, raw-to-header sample conversion, custom sample banks, sequencer behavior, sample playback, synth behavior, and effects.

Lore

Ekoparty states 2025 is the third consecutive year with an electronic badge. The official badge page names the creative and technical team and points attendees to a day-one badge reveal session.

Lifecycle

Add-ons & Upgrades

firmware workflow source-backed

Custom sample workflow

The repository documents RAW mono 22050 Hz sample export, Python raw-to-header conversion, AMY sample-bank configuration, UF2 flashing, and alternate synth-drum firmware.

Operational history

Issues & Camp Impact

image provenance upgrade note

The Ekoparty 2025 visual uses the repository's GPL-3.0 `2D_PCB1_2025-10-20.png` upstream raster render.

The South American entry now has a rights-cleared official upstream render with source URL, license, attribution, and processing notes while avoiding generated or placeholder imagery.
