Building interactive wall decor from junk phones
summary
Builds a literal collage called Cell Wall that runs multiple Android phones from a Raspberry Pi and Node.js to show split images, clocks and visualizers, claims ~€75 in parts, mounts phones with velcro and a USB hub, and uses adb (and appium‑adb) to manage devices over USB, adb reverse for HTTP and websockets for real time updates, and screen copy to mirror broken displays. Demos are flaky with some phones refusing to connect or needing rooting, but the system mostly works and integrates with Home Assistant webhooks.
