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.
Sold-out independent Puzzled Hackers LED meetup badge for DEF CON 34
Puzzled Hackers' own CTF checkout page calls this a limited-edition LED badge for DEF CON 34 and, in the August 4, 2026 source pass, lists $20 including tax, in-person pickup at the Linq 3535 / Circle Bar on Wednesday August 5 and Thursday August 6 from 7–10 PM PT, no shipping, and exhausted online allocations. A contemporaneous Puzzled Hackers Team announcement says the top 50 CTF participants received free-badge redemption on their accounts, remaining sales were capped to break even, further badges would move to random giveaways after the cap, and collection requires a meetup or arranged DEF CON handoff using an offline QR claim code. It also explicitly says the meetup is free and that an actual DEF CON badge is not required for the first Wednesday gathering. The sources support a real, independently distributed LED badge and a community CTF/meetup context, but not its physical construction, components, firmware, final quantity, free-claim count beyond the stated top 50, delivery, event authorization, DEF CON organizer affiliation, admission, or reusable-image rights.
