JawnCon 0x1 Modem Badge
Hayes SmartModem-inspired Wi-Fi modem badge
The JawnCon 0x1 modem badge was a wearable miniature Hayes SmartModem homage for the October 2024 Philadelphia-area hacker con. JawnCon's official write-up says it used RetroWiFiModem to simulate the AT command set and drive the LEDs, with a PCB carrying an ESP radio, level shifter, and vintage red LED front; Hackaday covered it as an ESP8266-powered Wi-Fi modem badge for early-Internet services.
