Biohacking Village DC33 Distiller BHV Badge

Compute Module 5 medical-AI badge

Biohacking Village's DEF CON 33 Distiller BHV badge was a CM5-based medical-AI badge built with SolaSec and PamirAI, combining local voice/chat interaction, e-ink UI, physical buttons, colored LEDs, battery power, and public BHV software branches.

Why It Mattered

It pushes village badges into portable edge-AI hardware: a full Raspberry Pi Compute Module 5 class board running local medical-assistant workflows rather than a simple microcontroller puzzle, while still fitting Biohacking Village's bio/CTF/event-art tradition.

Hardware

Public sources document a Raspberry Pi Compute Module 5 core on a custom PCB, an RP2040/Pico board-manager layer, e-ink display drivers, physical buttons, colored LEDs, built-in microphone, SD-card slot, Raspberry Pi GPIO headers, battery setup, USB-C Power Delivery charging requiring 9V/3A, and a 3D-printed enclosure. This pass did not recover a final public schematic, PCB release, bill of materials, or production count.

Software & Apps

The public trail describes a local medical-assistant chatbot with voice interaction, onboard LLM behavior, Distiller CM5 SDK and Distiller CM5 Python BHV branches under Apache-2.0 licensing, hardware/audio/camera/e-ink/SAM LED modules, Parakeet ASR/VAD, Piper TTS, optional Whisper, a conversational interface, LLM integration, MCP server support, local GGUF model switching, WiFi setup, debug mode, and SSH access.

Lore

The badge was built as a Biohacking Village, SolaSec, and PamirAI collaboration. Raspberry Pi's post-event article says PamirAI supplied the baseboard and software stack while SolaSec handled physical design, 3D-printed enclosures, and final assembly; the same article frames the badge as a private edge-AI medical chatbot and notes Biohacking Village's broader bio-based, technically challenging, CTF-oriented badge tradition.

Issues & Camp Impact

hardware-source caveat note

Public sources document the CM5 platform, custom PCB functions, enclosure, software branches, and user operation, but this pass did not recover a final public schematic, PCB/Gerber release, full bill of materials, or production count.

The catalogue keeps hardware claims to verified public documentation and avoids inventing component identifiers or manufacturing details.

medical guidance caveat warning

Public sources describe a medical chatbot that could listen and provide feedback or treatment ideas, but this catalogue has not validated clinical safety, model quality, or regulatory suitability.

The badge is recorded as an event artifact and AI interaction surface, not as a trusted medical device or medical-advice system.

missing rights-cleared image note

No Biohacking Village DC33 badge image is published because the official Wix page, PamirAI documentation, and Raspberry Pi article images have not been paired with explicit reusable image rights, attribution, and processing notes for catalogue publication.

The record remains source-backed and image-free rather than copying page media, documentation screenshots, article photos, social posts, or generated imagery.
