Root Access SAO (DEF CON 34)

Pre-event ATtiny1616 cedar interactive Simple Add-On for DEF CON 34

MakeItHackin's live Uberflux listing describes Root Access as a home-milled Tennessee-cedar add-on built for the DEF CON 34 badge and says it also works with a standard six-pin SAO header. Its August 4, 2026 marketplace snapshot lists $50 and a seller state of 15 sold from a listed total of 100, with BSides Las Vegas and Linq Circle Bar drop labels. The maker's public RootAccess guide independently identifies an ATtiny1616, ten addressable RGB pixels, eleven discrete LEDs, fifty built-in animations, a physical button, I2C address 0x50, and non-volatile USERROW state. It documents standalone operation and host-controlled lighting over I2C, plus separate GPIO 1 and GPIO 2 circuits that can be used as LED outputs or button inputs. This is a source-backed pre-event independent SAO record, not proof of final manufacture, actual drop handoff, every listed compatibility claim, safe electrical integration, DEF CON organizer affiliation, conference admission, or reusable-image rights.

Authors & Credits

source-named maker and operating-guide publisher

MakeItHackin

The product listing identifies MakeItHackin as the maker and the public RootAccess repository is under the MakeItHackin account. This records a narrow public maker/publisher role without inferring individual engineering authorship, manufacturing responsibility, DEF CON organizational status, or image-reuse authority.

Why It Mattered

Root Access is unusually well documented for a current BadgeLife-style SAO: the maker publishes both a high-level product description and an operational interface guide. That lets the catalogue distinguish confirmed standalone behavior, documented host control, and a deliberate GPIO experimentation surface from an inferred generic blinky. It also retains the necessary limits: a public protocol is not a license, an individual host experiment is not a universal compatibility result, and attractive maker photos do not establish reusable image provenance.

Hardware

The maker's guide identifies an ATtiny1616, ten individually addressable RGB pixels, eleven discrete LEDs of which four are PWM-capable, one physical button, I2C at address 0x50, and a standard six-pin SAO header. The product page adds home-milled Tennessee cedar, labelled breakout pads on both sides of the header, and independently selectable circuitry for GPIO 1 and GPIO 2. It says a GPIO line can be switched between button input and LED output modes, with a high/low polarity choice for the input path. No reviewed source supplies a schematic, BOM, board revision, component part numbers beyond the MCU, power/current budget, wood treatment or flammability information, electrical protection, SAO pinout validation, dimensions, production test record, compatibility matrix, compliance evidence, or final manufacturing report.

Software & Apps

The public guide says a tap cycles its fifty built-in animations, a roughly 700 ms hold turns outputs off, and a roughly three-second hold stores a boot-time favorite in USERROW. It documents I2C mode selection, all-off control, raw discrete-LED and RGB-pixel writes, and a two-byte status read; malformed raw writes are described as rejected without partial state changes. The repository currently exposes only a README and images, not firmware source, a binary release, build toolchain, flash procedure, code license, hardware-design license, test suite, update/recovery policy, or supported-host library. The catalogue therefore records a public operating guide, not an open firmware release or guaranteed integration recipe.

Lore

The marketplace calls the board Root Access and frames it as hand-paired local cedar and a PCB, with grain and colour varying by unit. It labels the project for DEF CON 34 but currently lists drops at BSides Las Vegas 2026 and two Linq Circle Bar nights rather than a confirmed official DEF CON distribution point. Those source labels establish independent Hacker Summer Camp and BadgeLife context, not a DEF CON-issued credential, host-badge inclusion, organizer authorization, venue approval, attendee entitlement, completed pickup, or a final production quantity.

Lifecycle

Add-ons & Upgrades

maker-described host GPIO interaction public product and guide description

Independent GPIO input/output circuitry

The maker says GPIO 1 and GPIO 2 each have separate hardware, switches, LEDs, and button-input options, independent of the animation engine and I2C controls. It says a host can drive an LED path or receive button input, with selectable logical polarity. No schematic, safe-voltage/current envelope, host-pin map, test matrix, or compatibility guarantee is published.

Home-milled cedar and header-breakout claim

The listing says the cedar was grown on a creator farm in Tennessee, milled at home, and paired with the PCB by hand; it also says the header pins break out to labelled solder pads on both sides. The source does not give wood treatment, dimensions, mechanical durability, fire-safety, sourcing chain, production count, assembly instructions, or final quality-control information.

I2C host-control and status interface

The guide identifies I2C address 0x50 and documents built-in-mode selection, all-off control, raw discrete and RGB LED writes, plus a two-byte status response. It says malformed raw writes are rejected without partial state changes. This is a published operating interface, not a warranty of host compatibility, electrical safety, bus arbitration, command support by a particular badge, or a software library.

ATtiny1616 standalone animation and USERROW surface

The guide identifies an ATtiny1616, ten addressable RGB pixels, eleven discrete LEDs, fifty animations, a button, and non-volatile USERROW storage for a favorite and last-played animation. It describes tap and hold behavior, but does not supply firmware source, a binary release, electronics test data, a battery/runtime profile, or final-unit verification.

Issues & Camp Impact

GPIO host behavior, interoperability, and safety boundary note

The maker describes separate GPIO LED-output and button-input options, but does not publish a current/voltage envelope, signal-timing specification, host pin mapping, a DC34 host result, contention protection analysis, switch-state guidance, or tests with other SAO devices. The source's general standard-SAO compatibility claim does not close those gaps.

Readers can identify the intended experimentation surface without assuming every host, GPIO mode, cable, orientation, or shared bus configuration is safe or interoperable.

I2C guide, firmware, source, and licensing gap note

The README documents behavior and control traffic, but the reviewed repository root contains only that README and an images directory. No firmware source, release binary, build toolchain, flash procedure, schematic, hardware-design archive, test suite, dependency list, code license, documentation license, or update/recovery policy was identified.

The catalogue links the documented interface without presenting it as an open-source firmware release, reproducible hardware design, or supported integration package.

The maker says Root Access was built for the DEF CON 34 badge and lists related summer-camp drops, but it does not say the item is issued by DEF CON, included with registration, grants admission, replaces a Human badge, has organizer endorsement, or has confirmed venue authorization.

The catalogue classifies Root Access as an independent pre-event Simple Add-On associated with DEF CON 34, not an official credential, organizer-issued badge, or access item.

No Root Access SAO image is published because the reviewed marketplace page and repository images do not pair a selected factual badge image with a reusable license or explicit permission basis, attribution, source URL, and processing notes.

The record remains source-backed and image-free rather than copying listing photographs, repository images, screenshots, social media, placeholders, or generated approximations.

The catalogue preserves a dated seller snapshot without converting it into a completed DEF CON or Hacker Summer Camp distribution report.
