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.
Lifecycle
The official write-up identifies the Hayes SmartModem as the badge's visual and command-set inspiration for the late-1980s/early-1990s event theme.
The case was printed in three PLA pieces, used integrated PCB slots and snap clips, and avoided screws or extra assembly hardware.
JawnCon describes settling on pulsed infrared laser marking for the front labels, with about 45 seconds per badge and explicit open-air laser PPE warnings.
JawnCon says the badge used RetroWiFiModem to simulate Hayes-style AT commands and control the LEDs.
The official write-up says the badge shells were printed on one Prusa MK4 over about a month and a half with full-plate front/back batches.
Operational history
The catalogue preserves both source trails and avoids asserting a single microcontroller family until a JawnCon-specific schematic, BOM, or firmware fork is recovered.
The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The record stays anchored to the official write-up and upstream firmware repository without inventing exact board files, pin maps, or firmware modifications.
