SauceBot / Arduino Sopracciglio electronic badge with a post-event KiCad archive
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.
People
Official Open Sauce overview, schedule, and ticket pages establish the 2026 San Mateo technology and creator festival. This is an event-context credit, not a claim that the organizer owned the public badge source archives or controlled all badge distribution.
SourceThe repository root MIT license names Copyright 2026 Caleb Marting, and an independent attendee README refers to the badge designer as Caleb while linking the source archive. This credit is limited to named design/source-publisher evidence, not sole manufacture, fulfilment, or image authority.
SourceThe putnam README names Gerard Hudson as helping make the overnight custom firmware project. This is a narrow collaboration credit and not a claim of original badge design, manufacture, distribution, or media authority.
SourceThe named public GitHub account publishes a replacement firmware archive and first-person account of receiving an eyebrow module at Open Sauce 2026. This is a scoped custom-firmware and attendee-provenance credit, not an assertion of original badge design, manufacturing, organizer authority, or image rights.
SourceIt expands the compendium with a current California maker-festival badge whose public physical-build, firmware, and KiCad sources record an unusually direct post-event community-hacking outcome, while retaining clear boundaries around official organizer ownership, distribution, production, and image provenance.
The designer README calls the core an Arduino Sopracciglio T-piece compatible with Arduino MKR Zero, and lists a CMA-4544PF-W microphone, 6x6 mm tactile button, three 5 mm red LEDs, and BS-02-A1AJ010 battery holder. It documents optional two 6-pin SAO headers and one 2-pin battery-only header, while the source tree includes native KiCad PCB and schematic files. The record does not infer an exact delivered bill of materials, component substitutions, battery chemistry, electrical limits, test results, or safety validation for every event unit.
The public archive contains Bop It firmware and examples, and describes microphone, accelerometer, button, and left/right touch actions. The designer notes that attendees produced four new games, while a separate attendee repository preserves a replacement firmware project and describes the original as a Bop It-style game. This dossier records the published source context without reproducing programming, modification, or operating instructions or treating any checkout as a final deployed release.
Open Sauce's official pages place the July 17-19 technology and creator festival at San Mateo County Event Center. Caleb Marting's archive was published after the event and invites further projects for the next festival. An independent attendee record says a Saturday eyebrow-module handoff led to a three-hour overnight firmware project and Sunday demonstrations, corroborating a badge-hacking culture around the physical event artifact. The organizer's public pages do not directly link the source archive or state ticket eligibility, manufacturing count, or recipient outcome.
Lifecycle
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.
SourceThe 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.
SourceOfficial 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.
SourceThe 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.
SourceThe 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.
SourceThe 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.
SourceOperational history
No participant count, entitlement, price, purchase result, or universal issuance is inferred from a public source archive or a single attendee project's account.
The record preserves the documented design and component outline without calling it a fabrication recipe, safety assessment, universal compatibility result, or final production specification.
The catalogue reports the valuable source and community-hacking trail without calling any checkout a final, authenticated, supported, or universally deployed badge image.
The catalogue credits only named, source-supported roles without inferring sole authorship, production responsibility, distribution control, trademark authority, or image permission.
The record remains source-backed and image-free rather than copying repository photos, board graphics, event media, screenshots, logos, or generated/approximate imagery.
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.
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.
