Independent ATtiny814 24-NeoPixel minibadge holder offered for DEF CON 34
Cabinet of Distinctm1nd's live Beelzebub Minibadge Holder listing is a $45 offer that displayed sold out in this August 4, 2026 source pass and says DEF CON pickup is only for August 6-8 pickup attendees. The maker describes 24 NeoPixel LEDs, an ATtiny 814, USB-or-battery power, custom or pre-programmed themes, and an assembled board whose minibadge headers and optional battery holder still require soldering; it also says shown minibadges are not included. The public `distinctm1nd/beelzebub_minibadge_holder` repository corroborates a holder for five minibadges, a 24-LED source layout, button-selected theme code, and KiCad/BOM material. Its hardware archive includes a filename with `saintcon_2025`, so it is a useful implementation and lineage source, not proof of a completed SAINTCON distribution, an unchanged final 2026 build, final fulfillment, official DEF CON issuance, a complete source-license grant, or reusable-image rights.
People
The public Beelzebub 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.
SourceBeelzebub is a documented current minibadge-holder artifact rather than an inferred accessory: its own storefront states the intended DEF CON pickup context and partial-assembly terms, while the public tree exposes both an electronic lighting implementation and fabrication material. The dossier keeps its source lineage, holder capacity, power, programming, fulfillment, and licensing limits explicit instead of converting a live store and public source tree into a finished, universally compatible, or officially issued badge claim.
The maker's product page calls Beelzebub a horror-themed minibadge holder with 24 NeoPixel LEDs, an ATtiny 814, USB-or-battery power, and optional battery-holder/minibadge-header soldering. The public repository README says it holds five minibadges and identifies a three-pin Sneaky Connector for programming. Its hardware folder contains KiCad PCB, project, and schematic files, a BOM workbook, and a `beelzebub_expansion_board_saintcon_2025_v2.zip` archive. The sources do not establish that these files exactly match a sold or pickup unit, the final ATtiny package/clock/fuses, NeoPixel model/color order/current, USB implementation, battery chemistry/voltage/holder/protection, regulator, power budget/runtime, minibadge-header pinout or electrical/mechanical standard, exact five-slot configuration, board materials/dimensions, assembly/test procedure, safety guidance, compliance, or compatibility with any particular minibadge.
The public `beelzebub_firmware_v1.ino` source uses AVR headers and defines four eye LEDs plus twenty wing LEDs, a button input, ten named LED modes, a 200 ms update interval, and button-driven mode cycling. It includes routines that emit per-pixel color data and toggles pins labelled for minibadge clock control. That supports a source-level programmable-light behavior, but it does not establish the final factory firmware, a supported programmer/toolchain configuration, exact board/fuse settings, release/tag mapping, flashing or recovery instructions, whether every sold unit has that source loaded, performance/accessibility characteristics, security review, warranty/support, or an explicit LICENSE/COPYING grant.
The maker frames Beelzebub as a horror-themed display for minibadges and says the pictured minibadges are not included. Its product page specifically directs buyers to choose DEF CON pickup only when they plan to collect at DEFCON on August 6-8, 2026; the public DEF CON 34 Badgelife response separately lists Beelzebub Minibadge Holder as a new $45 badge with the maker site and repository. Those sources document an independent pre-event acquisition association, not a DEF CON organizer product, admission item, universal attendee benefit, completed pickup, artwork/character-rights clearance, or authorization to reuse its storefront/repository media.
Lifecycle
The repository README calls Beelzebub a holder for five 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 twenty-four NeoPixel LEDs, an ATtiny 814, USB-or-battery power, and custom or pre-programmed themes. The public firmware defines four eye and twenty wing LED arrays plus color/mode code. The sources do not establish LED model/current, exact final color order, controller package/fuses, 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.
