ZePass: Digital Badges communicating
summary
Hardware badge runs a CircuitPython fork called ZOS driving a low‑res e‑ink display and uses Floyd–Steinberg dithering to convert images. Android control moves to a Kotlin KMP library powering Compose UI plus web/terminal clients; last year shows ~100 commits, ~100 contributors and 100+ badges given out. New add‑ons are a Wi‑Fi extension, keyboard and battery; badges open raw TCP, implement HTTP to a Ktor server and post to zbatch.api/zpath; Gemini and DALL·E generate profile text and images.
