Give your e-ink Raspberry Pi a new life. Ink Cartridge turns a tiny e-ink device — powered by a Raspberry Pi Zero 2 W — into a pocket-sized console you actually want to pick up. Browse an open, community-built library of "cartridges," load them on in a single tap, and play or glance at them right from your phone over Bluetooth. No cables. No web UI. No account. PLUG IN A CARTRIDGE • Browse a curated, open-source catalog of cartridges — games, puzzles, and glanceable tools • Install, update, and switch them with one tap • Launch and play them straight from your phone over Bluetooth • Push live data — like local weather — to the e-ink screen automatically • Change what your device does in seconds KEEP AN EYE ON YOUR DEVICE • Live status at a glance: battery, uptime, mode, and what's on screen • Home-screen widget and local notifications for status changes • Quick controls for a device you own BUILT FOR THE OPEN-SOURCE COMMUNITY Ink Cartridge is made for makers and tinkerers. A cartridge is just a small Python file plus a manifest and a UI described in plain JSON — the app renders the controls for you, so there's no app to rebuild and nothing to compile. Write your own, share it through the open catalog, and anyone can install it from their phone. • Open, hackable cartridge format • A community catalog anyone can contribute to • Your API keys stay encrypted on your phone • Simple, transparent permissions ONE APP, A GROWING ECOSYSTEM We're starting with the Raspberry Pi Zero 2 W e-ink build — with room to support many more small e-ink gadgets over time. One companion, an ever-growing shelf of cartridges. Ink Cartridge is a companion and launcher for a device you own, talking to it locally over Bluetooth. It does not capture or decrypt any network traffic. Grab your e-ink gadget, plug in a cartridge, and make it yours.
