Las Vegas Convention Center, Las Vegas, Nevada / Hacker Warehouse Vendor Booth · United States · 2025
The Tipsy Badge was an independent DEF CON 33 electronic badge by seeess, sold at the Hacker Warehouse vendor booth, with public CC BY-NC 4.0 repository documentation, firmware, a badge photo, 2xAAA power, RP2040 control, TFT display, buttons, LEDs, SAO port, custom photo storage, and galvanic vestibular stimulation modes.
Lifecycle
The hardware list includes one 1.69bis SAO port plus conductive pads, 3.5 mm lead, elastic band, lube, custom lanyard, spare batteries, and battery clip.
The README describes a Stroop-effect color game where positive or negative shock reinforcement can be configured before play.
The README says the badge was sold at the Hacker Warehouse vendor booth during DEF CON 33 and that half of profits went to the Tor project.
The repository guide documents Earle Philhower RP2040 board-manager setup, required Adafruit libraries, 2 MB sketch/filesystem partitioning, upload, and copying data files after first boot.
The README and firmware document a Raspberry Pi Pico / RP2040-class badge with two AAA batteries, TFT display, buttons, LEDs, DAC drive, current/voltage monitoring, and electrode output hardware.
The badge splits flash into code and filesystem partitions and exposes a USB mass-storage volume where users copy 128x160 TGA images into `blingpic/` for display on the badge.
The badge manual documents calibration plus steering and wobble modes that affect perceived left/right balance through conductive electrode pads.
Operational history
The catalogue treats the Tipsy Badge as an independent DEF CON 33 badgelife release while keeping the official DEF CON 33 badge record separate.
The record has a real source image, attribution, license basis, retained local source original, and optimized WebP delivery file rather than generated, placeholder, social-media, or screenshot imagery.
The catalogue can publish the selected image as a credited noncommercial reference asset, but downstream reuse should preserve the noncommercial restriction and attribution.
The catalogue records the device as an event artifact and badgelife experiment, not as a safe consumer medical or therapeutic device.
User-facing wording preserves the practical safety boundary around operating surviving badges or reproductions.
