Seasides 2026 Roulette Badge

Maker-documented ATtiny85 Hardware Village CTF badge soldered in Goa

The official Seasides and HW101 pages establish a Goa Hardware Hacking Village where people soldered take-home badges and worked on a hidden hardware/firmware challenge. A public project-owner archive calls a concrete board the Seasides 2026 Roulette Badge, says that more than 300 participants assembled it live, and publishes its C firmware, schematic, and Gerbers. The archive makes this a source-backed maker-documented instance of the village badge, but the official event pages do not independently name the Roulette design or confirm that every village or conference badge used that exact final configuration.

Why It Mattered

This replaces a purely generic village-badge description with a preserved, maker-documented ATtiny85 build and CTF surface without turning a project-owner account into unsupported organizer issuance, universal attendee allocation, or complete production proof.

Hardware

The commit-pinned maker README identifies an ATtiny85 running from its internal 8 MHz oscillator, a 74HC595 shift register, and eight LEDs. It documents ATtiny85 PB3/PB4/PB0 links for the shift-register data and clocks, PB2/PB1 as a software-UART/output-and-input-button surface, and labeled VCC/GND connections. The repository also exposes a schematic PDF and Gerber archive. Its VCC labels allow +5 V or +3.3 V, but the reviewed material does not establish the final event-unit power source, current draw, battery, protection, complete BOM, board revision, test results, or electrical-safety/compliance evidence.

Software & Apps

The maker README identifies public `badge.c` firmware for an eight-stage embedded CTF, a 1,200-baud software-UART challenge interface, EEPROM-backed progression, encoding puzzles, and animation modes. It provides AVR-toolchain and programmer workflows, but this catalogue does not treat the repository as proof that every physical event unit shipped that firmware revision, that every challenge remained available, or that the code/design/media have a public reuse license.

Lore

Seasides' official 2026 site links the Hardware Hacking Village as a conference security village, and HW101 frames it around soldering, hardware talks, CTF activity, and badge-challenge prizes. Rahul Thareja (`c1ph3r-fsocitey`) identifies himself as the Roulette badge's designer and builder. The contemporary official wording about enough badges for attendees and the later maker statement about 300-plus live assemblies are retained as separate source claims rather than merged into a confirmed recipient ledger or organizer-issued credential claim.

Add-ons & Upgrades

Hidden hardware and firmware challenge

The official source describes a hidden hardware/firmware challenge using reverse-engineering skills, with prizes for successful solvers. It does not independently identify the exact Roulette board, its eight-stage maker CTF, or a shared challenge implementation.

Conference-attendee soldering badge

The HW101 page says the village would have enough badges for everyone attending the conference and that participants could take home a custom badge after soldering it.

Eight-stage CTF and UART progression

The README describes an eight-stage embedded CTF, 1,200-baud software UART, EEPROM-backed progression, encoding challenges, and animation unlocks. It does not prove current availability, rules, solution handling, participant scope, service operation, safety review, or firmware parity across all physical event units.

ATtiny85 and eight-LED hardware baseline

The README identifies an ATtiny85 at an internal 8 MHz oscillator, a 74HC595 shift register, and eight LEDs, with data/clock/control pin mapping and VCC/GND labels. The source does not establish the final event-unit supply, battery, current budget, BOM, board revision, tests, safety evaluation, or compliance.

post-event source archive maker documentation published

Maker-declared Roulette source archive

Rahul Thareja's public, commit-pinned project calls the design the Seasides 2026 Roulette Badge, says more than 300 people assembled it live, and provides a C firmware, schematic, and Gerber trail. That is strong maker documentation of a real physical artifact, but the official event sources do not independently name the design or confirm the claimed count and unit parity.

Operational history

Issues & Camp Impact

distribution, participant-count, and recipient-scope caveat note

HW101 said there would be enough badges for everyone attending, while the maker README says more than 300 participants assembled the Roulette design live. Neither source supplies a final production count, serial/recipient ledger, independent attendee pickup report, relationship between the two quantities, excluded cohorts, leftovers, replacements, or evidence that all attendees received the same design/revision.

The record preserves both distribution-related statements without converting them into a confirmed universal issuance count or individual fulfillment history.

Confidence: separate official and maker statements
Status: planned availability and maker-reported live assembly; final ledger unrecovered
Timeframe: Seasides 2026
Source note: HW101 Hardware Hacking Village page and Rahul Thareja's commit-pinned Roulette Badge README.

maker-to-event provenance, final configuration, and source-license boundary note

Official pages establish a generic soldering badge and hidden challenge at the Hardware Hacking Village. Rahul Thareja's archive calls its design the Seasides 2026 Roulette Badge and provides technical source material, but the official event publishers do not independently name that board, authorize the claim, identify its final revision, or confirm it was the only or universal village badge. The repository's root exposes no license, so source code, design files, art, and photos are not treated as reusable.

The catalogue can identify a real maker-documented hardware artifact without representing it as an organizer-issued credential, a fully verified all-attendee unit, a specific final manufacturing configuration, or an open/reusable media release.

Confidence: official generic village evidence plus maker documentation
Status: individual artifact documented; official identity and reuse license absent
Timeframe: Seasides 2026 post-event source pass
Source note: HW101 Hardware Hacking Village page and Rahul Thareja's commit-pinned Roulette Badge README/source archive.

missing rights-cleared image note

No Seasides 2026 Roulette Badge image is published because neither the official village/conference pages nor the maker repository pair a specific badge photo or render with an explicit reusable license or permission basis, attribution, and processing provenance. The repository's root has no stated license.

The record stays image-free rather than copying official page imagery, repository photos, screenshots, social media, or generated badge art.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy; Seasides/HW101 pages; and the c1ph3r-fsocitey source archive.
