Hacker Con Badges

Open Sauce

Open Sauce 2026

The July 17-19, 2026 Open Sauce technology and creator festival in San Mateo. A post-event designer source archive documents a physical Arduino MKR Zero-compatible electronic badge and SAO ecosystem, while an independent attendee firmware archive corroborates badge hacking during the festival. Official Open Sauce pages establish the event, but do not directly publish the source archive or a distribution ledger.

Open Sauce 2026 Badge

Open Sauce 2026's SauceBot badge is documented by Caleb Marting's post-event public archive as an Arduino MKR Zero-compatible electronic badge with native KiCad sources, firmware, a microphone, button, red LEDs, battery holder, and optional Simple Add-On headers. The archive says at least two attendees hacked badges Saturday night and brought four new games on Sunday; an independent attendee firmware archive also describes receiving an eyebrow module and replacing the original Bop It-style firmware. Together the sources establish a real festival artifact and hands-on hacking trail, not a universal attendee allocation or organizer-owned source release.

badge expansion ecosystem

Simple Add-On community context

The designer README describes optional SAO headers and says add-ons could be found at Open Sauce, while the attendee archive reports several basic LED SAO modules handed out at the event. This does not prove universal availability, exact module count, connector compliance, power compatibility, safe attachment, or final event configuration.

documented badge platform

Arduino Sopracciglio and MKR Zero-compatible core

The designer README calls the badge's T-piece Arduino Sopracciglio and Arduino MKR Zero-compatible, while the independent attendee archive also describes a custom board based on Arduino MKR Zero. The record does not infer a chip-level bill of materials, exact board revision, supply behavior, or final population beyond the published statements.

event association

Open Sauce 2026 source-and-event trail

Official Open Sauce pages establish the July San Mateo festival. Caleb Marting's archive names the 2026 badge, and an independent attendee archive calls itself replacement firmware for the 2026 Open Sauce badge. This supports a strong physical-event association without saying the organizer owned either repository or issued the board as a universal credential.

firmware and community outcome

Original Bop It and four-game post-event hacking trail

The designer archive describes its Bop It firmware and says at least two people hacked badges Saturday night and showed four new games Sunday. The independent attendee README calls the original a Bop It-style game and documents a replacement project. The record preserves the outcome at a high level without reproducing game, programming, or modification instructions.

hardware source archive

Native KiCad source archive

The archive contains native KiCad PCB and schematic files plus footprint and asset directories. The catalogue links that research value without representing the current archive as a guaranteed exact production package, a ready-to-manufacture record, or a safety-validated build.

Open Sauce 2026 Badge designer README source detail

physical badge documentation

Documented input, LED, power, and header surface

The README lists microphone, tactile button, three red LEDs, battery holder, optional two 6-pin SAO headers, and a 2-pin battery-only header. It also describes microphone, accelerometer, button, and touch actions. This is a source-backed feature outline, not a complete production, power, electrical-safety, or compatibility specification.

Issues & Camp Impact

Open Sauce 2026 Badge note

distribution, purchase, and physical-handoff gap · post-event designer and attendee archives · physical badge use corroborated; recipient and purchase outcome unrecovered

The sources establish that physical badges and an eyebrow module were present during the festival, and the designer README has a future purchase-link note. They do not establish ticket eligibility, price, inventory, production quantity, registration handoff, recipient count, standard-versus-optional configurations, order history, shipment, completed sale, replacement, refund, or attendee-wide allocation.

No participant count, entitlement, price, purchase result, or universal issuance is inferred from a public source archive or a single attendee project's account.

Open Sauce 2026 Badge note

final hardware, power, and electrical-safety gap · README and KiCad archive review · component outline and source tree visible; production/safety record unrecovered

The archive identifies selected components, inputs, battery-holder footprint, headers, and native KiCad files, but reviewed sources do not establish a reconciled delivered BOM, component substitutions, battery chemistry/capacity, protection/charging behavior, electrical limits, current draw, thermal result, assembly quality, test plan, compliance result, final assembled configuration, or safe SAO/power compatibility.

The record preserves the documented design and component outline without calling it a fabrication recipe, safety assessment, universal compatibility result, or final production specification.

Open Sauce 2026 Badge note

firmware release and deployed-build gap · public source and independent attendee archive · source/context public; canonical deployed build unrecovered

The designer repository contains Bop It firmware and examples, and a separate attendee repository contains a replacement firmware project, but neither reviewed source tags a final production release, maps a versioned build to a particular event badge, defines a support owner, or publishes a complete recovery/update lifecycle. The attendee project is intentionally not treated as the organizer's or designer's canonical event firmware.

The catalogue reports the valuable source and community-hacking trail without calling any checkout a final, authenticated, supported, or universally deployed badge image.

Open Sauce 2026 Badge note

individual design, manufacturing, and fulfilment-role boundary · named designer and attendee collaboration sources · scoped named credits only

Caleb Marting is named by the root license and an attendee as the badge designer, and the attendee archive names putnam and Gerard Hudson for custom-firmware work. Reviewed sources do not allocate individual mechanical, electrical, firmware, artwork, fabrication, assembly, test, procurement, sales, handoff, support, or image-rights roles beyond those narrow facts.

The catalogue credits only named, source-supported roles without inferring sole authorship, production responsibility, distribution control, trademark authority, or image permission.

Open Sauce 2026 Badge note

missing rights-cleared image · local project policy and archive review · needs a rights-cleared, event-unit-specific original or upstream render

No Open Sauce 2026 Badge image is published because the repository's assembly photos, board graphics, and artwork candidates have not been paired with a selected factual event-unit identity, image-specific named attribution, unambiguous reuse basis, source URL, and local processing provenance together. The root MIT source license is recorded separately and is not assumed to resolve all image-specific facts.

The record remains source-backed and image-free rather than copying repository photos, board graphics, event media, screenshots, logos, or generated/approximate imagery.

Open Sauce 2026 Badge note

official organizer-to-source archive association boundary · official event and convergent public project sources · event and physical badge trail supported; organizer repository link unrecovered

Official Open Sauce pages establish the event but do not directly link the Caleb Marting or putnam repositories. Those public archives independently and specifically identify the 2026 Open Sauce badge, physical modules, and event hacking, but they do not demonstrate that Open Sauce controlled their publication, approved every current source change, or declared a standard attendee-credential policy.

The catalogue records a real event badge and public source trail without turning a convergent designer/attendee archive into an organizer-owned project or general credential claim.

Open Sauce 2026 Badge note

source-license, visual-asset, and branding scope boundary · repository root-license review · MIT software/documentation license recorded; separate scopes unresolved

The root repository contains an MIT license naming Caleb Marting for software and associated documentation, but reviewed sources do not separately allocate copyright or image attribution for every assembly photo, board graphic, logo/art layer, physical board, Open Sauce name/mark, or third-party component/library asset. The attendee replacement repository separately says it has no license.

The entry may link the respective source archives and license statements while keeping physical-artifact, media, branding, downstream reuse, and local-image rights scoped rather than inferred.
