SourceIt 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.
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.
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.
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
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.
SourceFour PCB-integrated resistive touch sensors control sample triggering, sequencer behavior, pitch shifting, and filtering through RP2040 ADC readings.
