When cell towers fail and Wi-Fi dies, a neighborhood-wide SOS grid can still shout for help-if you've got LoRa. Neighborhood Panic-Button Mesh is the hands-on, budget-savvy guide to wiring an entire block's worth of emergency alerts for under $300. Hardware hacker Priya Desai walks you through every solder joint, firmware flash, and range test, turning a handful of low-power radio modules into a self-healing, mile-spanning safety net.
Inside you'll learn how to
Pick the exact LoRa boards, antennas, and batteries that squeeze maximum range out of pennies. Follow the step-by-step build-from breadboard mock-ups to waterproof enclosures-no EE degree needed. Deploy a mesh network that hops signals house-to-house until help hears you. Add one-tap ""panic buttons,"" SMS/email gateways, and solar trickle-chargers. Rally neighbors with workshop scripts, printable flyers, and training checklists.
Whether you're safeguarding an urban high-rise, a rural valley, or a festival in the middle of nowhere, this book turns you into the local comms hero-ready to punch through chaos when every second counts.
