Notes
Original 1920x1080 TIB AV-Portal poster frame from the CCC Camp 2019 card10 assembly video, DOI 10.5446/43215, cropped to the visible card10 PCB on the assembly table, conservatively polygon-masked, scaled to the site badge canvas, and preserved as a transparent source cutout before WebP delivery conversion. This is a documentary video frame, not a studio packshot; the source frame is slightly soft but preserves the actual physical card10 hardware. The published badge.gallery delivery file is an optimized WebP generated from the rights-cleared local derivative/source with metadata stripped, WebP quality 82, and a maximum side cap of 1600 pixels when the source is larger; upstream source URL, license, and attribution remain unchanged.

Attribution Gap

No public individual author, designer, firmware, or team credits have been seeded for this badge yet. Add named credits only when a primary badge-team page, repository, talk, or other source identifies the people or team behind the work.

Why It Mattered

card10 pushed the camp badge toward everyday wearable form factors and app repository workflows.

Hardware

card10 includes ECG, Bluetooth Low Energy, optical pulse sensor, IMU with magnetometer, and environmental sensing, per public docs.

Software & Apps

Uses Hatchery as its app repository, with firmware updates and app installation documented through the card10 project.

Lore

The name references kardía, the Greek root for heart, matching the badge's biological signal theme.

Issues & Camp Impact

not-a-watch caveat note

Hackaday cautioned that card10 should not be mistaken for a watch, noting that timekeeping was effectively an afterthought and that setting the clock depended on the companion app because there was no battery-backed RTC.

The page separates card10's wearable form factor from ordinary smartwatch expectations and keeps the focus on sensors, BLE, and hackability.
