The ESP32-C6 WiFi Dojo, a pocket-sized WiFi practice range on the Nano ESP32-C6 v1.0. Three modes: WPA2/WPA3 practice AP, beacon flood with SSID cloning, and captive portal. Around $13 in parts, runs off any USB power bank.
An RTL-SDR running on a Pi4 decodes live POCSAG pager traffic and publishes it over MQTT. A $15 ESP32 touchscreen display subscribes and shows pages in a retro green-on-black UI. Full build guide including the CYD display config that took way too long to find.
A custom ESP32 build that subscribes to Meshtastic's encrypted MQTT topic, decrypts packets on the fly, and scrolls messages across a WS2812B 8x32 LED panel. Full build guide: parts, wiring, PlatformIO flashing from scratch, and MQTT setup.
