La Villa Hacker
The August 8-10, 2025 Spanish-language hacker-village edition whose official site provides event context and whose Electronic Cats repository documents the La Villa Hacker 2025 badge.
Las Vegas, Nevada / DEF CON 33 · United States · 2025
Electronic Cats' public La Villa Hacker 2025 Badge repository documents a village badge with OLED display, nRF24L01 radio, two-AAA power, Shitty Addon connector, KiCad hardware files, firmware sources, and a released VillaHacker.hex binary.
Lifecycle
The top-level README lists NRF24L01 as part of the badge technology stack.
The README lists a Shitty Addon connector, making the badge compatible with the wider SAO-style add-on ecosystem.
The README lists an OLED display as the badge's attendee-facing display surface.
The v1.0.0 release publishes VillaHacker.hex for badge reprogramming, while the README says badges come with pre-installed firmware.
The README lists a two-AAA battery holder as the badge power hardware.
Operational history
The badge record keeps those statements source-specific and avoids claiming a single verified final controller until the project publishes a reconciled BOM or final schematic note.
The catalogue treats the artifact as a source-backed La Villa Hacker 2025 badge without implying every village attendee received one.
The repository is used as evidence for badge facts, but no repository image or media asset is promoted into the public image archive.
The record remains source-backed and image-free rather than copying site media, repository screenshots, renders, social-media photos, or generated replacements.
