Xerox PARC chip shatters on command
Xerox PARC developed a chip that can shatter on command, demonstrating advanced materials technology. The chip's ability to break easily could have applications in security and safety systems. (techxplore.com)
Wes Bos documents turning cheap Wi‑Fi photo frames into a usable family dashboard, arguing that these devices - essentially low‑end Android tablets - should be free from vendor lock‑in and repurposed once purchased. After reviving a $500 Skylight calendar with dead Wi‑Fi, the same method is applied to a $50 Amazon frame to show the approach is repeatable and affordable. The central claim is practical: rather than pay subscription services or be stuck with crippled hardware, owners can root and reflash these frames to run custom software that better serves a household.
The write‑up and accompanying video detail the hands‑on steps and concrete fixes: force recovery/debug mode, connect over ADB, root the device, remove stock apps, and use USB OTG host mode plus an inexpensive USB Wi‑Fi dongle to restore networking on units with failed radios. A modern Chrome WebView is installed to host a web dashboard, swap memory is tuned, and the motion sensor is wired to dim the screen when unused. The final dashboard is backed by an agent that parses school emails into calendar events, reminders and spelling‑word lookups. All code and instructions are published on GitHub (wesbos/photo-frame-dashboard), making the hack reproducible for others.
