Tildagon
ongoing
Breadboard Tester
naomi's Breadboard Tester is scoped to breadboard hexpansions and toggles eGPIO and GPIO pins, making hardware bring-up and pin probing part of the app-store lifecycle.
Tildagon
community example
Goosespansion
Skyler Mansfield's Goosespansion is a named PCB hexpansion with published files, showing how the Tildagon gallery tracks both creator attribution and reusable fabrication data.
Tildagon
community example
Ducks hexpansion
Tiff's Ducks hexpansion records the purely expressive side of the ecosystem: camp-lore ornamentation using the same connector format as active electronics.
Tildagon
community example
Petals

Tildagon
ongoing
Forced hexpansion detection and recovery
Official docs preserve post-event recovery behavior: firmware v1.6.0+ can force hexpansion detection with button chords, and failed updates may require better WiFi or flashing.
Tildagon
community example

Tildagon
current EMF 2026 lifecycle
Hat Village
pikesley's Hat Village app is listed as the official app of Hat Village at EMF 2026, showing that Tildagon app distribution is already carrying future village-specific software.
Operational history
Issues & Camp Impact
Tildagon
moderate
The hardware overview warns that eGPIO does not work in firmware v1.6.0, a concrete compatibility caveat for hexpansion or GPIO-dependent work.
Hardware add-ons and examples may depend on firmware version, so the badge needs lifecycle tracking rather than one-time hardware notes.
Tildagon
note
The MD Updater app-store entry describes a real Megadrive-interface firmware updater but currently lists a placeholder source repository URL.
The compendium keeps the app and author record while flagging that source-code provenance is weaker than other Tildagon app entries.
Tildagon
note
Tildagon is not a fixed one-camp artifact: EMF says the badge is intended to return across events, while the live app directory and hexpansion docs continue to accumulate apps, add-ons, and recovery notes.
badge.gallery needs to treat Tildagon as a lifecycle record with recurring app, firmware, and hexpansion updates instead of a static EMF 2024 page.
Tildagon
note
Official docs document replacement paths for multiple fragile or field-repairable components, including display-related parts, LEDs, and battery connectors.
The maintenance record matters because reusable camp badges only stay useful if spare-part and repair workflows survive after the event.
