EMF 2026 Spaceagon Badge

Released Tildagon frontboard revision with reusable base and new input surface

Spaceagon is the released 2026 update to EMF's reusable Tildagon badge platform. The official completed-event, order, assembly, and API pages document a complete kit or a 2024 upgrade path, the new Spaceagon frontboard, and a distinct input surface while retaining the Tildagon base and hexpansion ecosystem.

Why It Mattered

It turns the Tildagon's two-year reusability promise into a documented second event edition: an owner could retain the main board, battery, screen, and existing hexpansions while changing the event-specific frontboard instead of discarding a complete badge.

Hardware

Official documentation identifies an ESP32-S3 platform with 2 MB PSRAM and 8 MB flash, USB-C, WiFi, BLE, a round screen, six hexpansion connectors, LEDs, power management, motion sensing, and an IMU. The 2026 Spaceagon frontboard adds six A-F buttons, a five-way joystick, a twelve-sensor clock-form touch strip, two side proximity sensors, and compass access. Complete kits contained a Spaceagon frontboard, backboard, screen, and battery; the upgrade kit contained frontboard, midboard, nubbin, and FPC cable.

Software & Apps

Spaceagon runs the MicroPython-based Tildagon software and exposes its A-F buttons, joystick, touch sensors, proximity sensors, and frontboard identifier through published APIs. The assembly guide requires a firmware update before fitting the new frontboard; otherwise its buttons do not work, though the joystick remains usable to complete the update. The reviewed sources do not establish a separately versioned 2026 firmware release, reproducible build, or a complete 2026 hardware archive.

Lore

EMF framed Spaceagon as a deliberately small, field-upgradable change: the new top protects formerly fragile LEDs, buttons, and screen in a two-board sandwich while preserving existing app and hexpansion compatibility. EMF also released its first official hexpansion, the optional Keebdexpansion keyboard, for ticket holders. Public blog imagery remains a labelled prototype with temporary artwork, so no image is reused here.

Lifecycle

Add-ons & Upgrades

official assembly verification app officially documented

Spaceagon Test app

The assembly guide points owners to the Spaceagon Test app through the badge app store, using code 21230442 to verify the completed 2026 badge.

Compatibility: Assembled EMF 2026 Spaceagon running the required updated badge firmware.

official keyboard hexpansion officially documented; post-event listing sold out

Keebdexpansion keyboard

EMF's first official hexpansion is a full-layout, RGB-backlit keyboard that helps with text input and automatically installs its driver when plugged in.

Compatibility: Tildagon or Spaceagon hexpansion interface; availability was limited to EMF 2026 camp ticket holders through the official shop.

official reusable-platform upgrade officially documented; post-event listing sold out

Spaceagon frontboard upgrade kit

EMF offered a frontboard, midboard, nubbin, and FPC cable kit for a 2024 Tildagon owner, preserving the prior main board, battery, screen, and hexpansions while changing the event-specific frontboard.

Compatibility: 2024 Tildagon base with the Spaceagon upgrade kit; firmware update required before fitting the new frontboard.

Operational history

Issues & Camp Impact

firmware-update and physical-assembly caveat moderate

The official guide says firmware must be updated before installing the 2026 frontboard; otherwise the new buttons do not work, although the joystick can still be used to update. It also instructs owners to disconnect the battery by its connector rather than its wires and to use isopropyl alcohol to release the battery's glue dots.

Spaceagon is a maintainable upgrade path, but it is not a plug-and-forget accessory: a prospective owner needs to account for firmware state, frontboard disassembly, display and battery connectors, and the guide's physical handling steps.

Confidence: official assembly guide
Status: documented owner workflow
Timeframe: Spaceagon assembly and update
Source note: Spaceagon Assembly (2026) documentation.

2026 hardware archive and release-scope gap note

The reviewed official sources publish feature, assembly, API, app, and model-link material, but this pass did not recover a complete, separately versioned 2026 package of final frontboard PCB layout, schematic, BOM, Gerbers, manufacturing files, firmware build/release instructions, and explicit license terms. The public base-platform software repository is therefore tracked as context rather than promoted to a complete Spaceagon release archive.

Readers can use the documented upgrade and programming surface without assuming full hardware reproducibility, a specific final firmware version, redistribution rights, or that any public moving branch precisely matches every 2026 shipped kit.

Confidence: official source review
Status: public operational documentation; complete release archive not recovered
Timeframe: post-event source pass
Source note: Official Spaceagon announcement, order listing, assembly/API documentation, and linked public base-platform software repository.

completed-event allocation and fulfillment boundary note

EMF confirms that the July 2026 event is complete, and the official listing says all badges and components required on-site pickup and now displays the products as sold out. Neither source establishes production quantity, order count, individual collection, no-show handling, delivery, replacement, repair support, or a universal attendee allocation.

The catalogue records a completed event and a documented acquisition route without turning a sold-out post-event listing into a claim that every offered kit was manufactured, collected, or issued to all attendees.

Confidence: official completed-event and badge-listing sources
Status: event complete; individual pickup records unavailable
Timeframe: post-event source pass
Source note: Electromagnetic Field 2026 home page and official badge order listing.

missing rights-cleared image note

No Spaceagon image is published because the official announcement labels its photographed Spaceagon as a prototype with temporary artwork, while the reviewed official event, order, documentation, and model-link sources do not provide one final artifact image or official raster with a reusable license or explicit permission basis, attribution, source URL, and processing record.

The completed United Kingdom record remains source-backed and image-free rather than copying prototype artwork, documentation photos, cloud-model previews, attendee media, screenshots, placeholders, or generated approximations.

Confidence: local project policy and primary official sources
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy plus the official Spaceagon announcement, badge listing, and documentation.
