Independent ATtiny814 five-NeoPixel minibadge holder offered for DEF CON 34
Cabinet of Distinctm1nd's live Krampus Minibadge Holder listing is a $45 offer that displayed sold out in this August 4, 2026 source pass and limits DEF CON pickup to August 6-8 pickup attendees. The maker describes five NeoPixel LEDs, an ATtiny 814, microcontroller development-pin access, USB-or-battery power, and custom or pre-programmed themes; it says minibadge headers and the optional battery holder require soldering and shown minibadges are not included. The public `distinctm1nd/krampus_minibadge_holder` repository corroborates an ATtiny814 holder described as holding six minibadges, a five-LED firmware layout, button-selected theme code, and KiCad/BOM material. Its hardware archive includes a `saintcon_2025` filename, so the tree is an implementation and lineage source—not proof of completed SAINTCON distribution, final 2026 production parity, fulfillment, official DEF CON issuance, a complete source-license grant, or reusable-image rights.
People
The public Krampus source repository is published under the distinctm1nd GitHub account. This records visible repository-publisher context only, not sole authorship, final 2026 production responsibility, SAINTCON distribution, DEF CON issuance, or media-rights authority.
SourceThe live product page is published by Cabinet of Distinctm1nd. This records a public storefront-publisher role only, not sole hardware/art/firmware authorship, manufacture, DEF CON organizer status, completed fulfillment, or image-reuse authority.
SourceKrampus is a separately evidenced electronic minibadge holder, not merely a second name in a marketplace catalogue. Its maker listing and public source tree form a concrete DEF CON 34 pre-event trail while the record preserves key distinctions: repository-held technical files do not settle the final pickup build, the store's holder presentation does not guarantee minibadge compatibility, and maker use of open-source language does not replace an explicit license review.
The maker's product page identifies five NeoPixel LEDs, an ATtiny 814, microcontroller development-pin access, USB-or-battery power, and optional battery-holder/minibadge-header soldering. The public repository README says Krampus holds six minibadges and identifies a small development connector plus a three-pin Sneaky Connector for programming. Its hardware directory contains KiCad PCB, project, and schematic files, a parts-list workbook, and `krampus_minibadge_holder_saintcon_2025.zip`. The sources do not establish final 2026 board population, the exact ATtiny package/clock/fuses, NeoPixel model/color/current, USB implementation, battery chemistry/voltage/holder/protection, regulator, current draw/runtime, development/programming connector pinout or safe use, minibadge-header pinout/standard, exact six-slot configuration, materials/dimensions, assembly/test procedure, safety guidance, compliance, or compatibility with any particular minibadge.
The public `krampus_firmware_v1.ino` source uses AVR headers, defines a five-element eye/tongue LED array, a button input, ten named LED modes, a 200 ms update interval, and button-driven mode cycling. It emits per-pixel color data and toggles pins labelled for minibadge clock control. That evidences a source-level programmable-light implementation, but it does not establish the final shipped firmware, toolchain/programmer settings, board/fuse configuration, release/tag mapping, flashing or recovery path, whether every listed unit carries this revision, accessibility/performance behavior, security review, warranty/support, or an explicit LICENSE/COPYING grant.
The maker's store frames Krampus as a minibadge holder and warns that it does not come with the shown minibadges. Its pickup terms explicitly name DEFCON on August 6-8, 2026, while the public DEF CON 34 Badgelife response separately lists Krampus Minibadge Holder as a new $45 badge with the maker site and repository. This records an independent current marketplace association rather than organizer issuance, event admission, universal access, a completed handoff, verified creator/franchise-rights clearance, or a reusable-media permission.
Lifecycle
The repository README calls Krampus a holder for six minibadges, while the store says the board is assembled except for minibadge headers and an optional battery holder, and excludes shown minibadges. Those statements do not establish the exact slot layout, header/pinout, MiniBadge standard, power/clock/data behavior, soldering skill or safety requirements, attachment force, mechanical fit, contents of every unit, or compatibility with a particular minibadge.
SourceThe maker describes five NeoPixel LEDs, an ATtiny 814, development-pin access, USB-or-battery power, and custom or pre-programmed themes. The public firmware defines a five-element LED array plus color/mode code. The sources do not establish LED model/current, exact final color order, controller package/fuses, development-pin or USB/power implementation, power budget, battery type, safety, or final production parity.
SourceThe official product page showed $45 and sold out in this August 4, 2026 pass, and says buyers should select DC pickup only when planning DEFCON pickup on August 6-8. These statements do not establish inventory history, payment, manufacture, drop location/time, email notice, completed pickup, shipment, refund, replacement, or support outcome.
SourceThe public firmware declares ten LED modes, button-driven cycling, per-pixel color output, and pins labelled for minibadge clock control. This documents a possible firmware interaction surface without claiming that all current units expose the same button, pins, timing, modes, firmware revision, programming path, accessibility behavior, or support.
SourceOperational history
The record preserves a valuable public source trail without treating an archive filename as proof of a prior conference handout or claiming that the current listed unit is new, unchanged, or technically identical to the archived design.
The catalogue links a public implementation trail without converting marketing language into a legal reuse grant, reproducible build, supported reflashing path, final firmware release, or warranty.
The dossier records source-described creative framing without asserting ownership, franchise/religious or cultural affiliation, sponsorship, endorsement, authorship, or media-reuse authority.
The catalogue records a source-backed independent event association without portraying the holder as official conference hardware, an admission credential, a universal attendee benefit, or confirmed organizer distribution.
Readers can identify a real electronic holder without treating it as universally interchangeable, electrically safe, mechanically compatible, or ready to use with every minibadge.
The current record remains source-backed and image-free rather than copying Shopify product photos, repository images, KiCad previews, screenshots, social media, placeholders, or generated approximations.
The catalogue preserves an observed marketplace state and intended pickup path without presenting it as a completed limited run or delivery report.
