current
External LoRa antenna and case
LoRa depends on the supplied external antenna, and the repository includes an OpenSCAD case intended to hold battery, antenna, and LEDs.
BornHack 2024 Badge
historical
Firmware examples and case branch
The README links Badge.Team firmware, a flasher, Rust examples, workshop firmware, and a 3D printed case branch.
BornHack 2026 Badge
linked pre-event
Open hardware and Rust firmware repositories
The main Badge.Team page links Codeberg homes for Cyber Ægg hardware and firmware, with the hardware docs identifying KiCad files and the software summary pointing at Rust/Embassy firmware work.
Operational history
Issues & Camp Impact
The PCB antenna shape is not connected because the selected LoRa module variant uses an external u.FL/IPEX connector.
Users need the supplied external antenna and should avoid sticking it directly to the copper-heavy PCB because that can reduce RF performance.
BornHack 2026 Badge
note
The BornHack 2026 visual now uses an optimized WebP derived from the official `imgs/badge-front.png` Cyber Ægg front render in the MIT-licensed Ranzbak/bornhack2026-hardware Codeberg repository.
The public badge page, image archive, and API point at a licensed upstream repository render with source URL, MIT license basis, attribution, and processing notes while avoiding generated, placeholder, social, or uncleared imagery. The render is a pre-event prototype illustration, not a shipped-product photograph, and the record keeps that distinction explicit.
BornHack 2024 Badge
note
The BornHack 2024 visual now uses an optimized WebP derived from a transparent cutout derived from the CC BY-SA 4.0 `Pictures/bornhack_badge_2024_lightblue.jpg` photo in the official case branch.
The public badge page, image archive, and API point at a licensed physical badge-in-case photo derivative with source and attribution preserved.
BornHack 2018 Badge
note
No BornHack 2018 badge image is published because the current source trail has not been paired with a reusable original badge photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
The record remains source-backed and image-free rather than copying repository diagrams, documentation screenshots, event media, attendee photos, placeholders, or generated approximations.
BornHack 2019 Badge
note
No BornHack 2019 badge image is published because the current source trail has not been paired with a reusable original badge photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
The record remains source-backed and image-free rather than copying repository diagrams, documentation screenshots, event media, attendee photos, placeholders, or generated approximations.
BornHack 2020 Badge
note
No BornHack 2020 badge image is published because the current source trail has not been paired with a reusable original badge photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
The record remains source-backed and image-free rather than copying repository diagrams, documentation screenshots, event media, attendee photos, placeholders, or generated approximations.
BornHack 2026 Badge
note
BornHack 2026 starts on July 15, 2026, so the current Badge.Team docs are pre-event even though they now document Cyber Ægg hardware, software concepts, source links, and sponsors in detail.
The entry can describe planned public specs, but must be revisited after the badge ships and attendees document field behavior, production errata, app maturity, and distribution outcomes.
