The JawnCon 0x1 Badge Dials Up A Simpler Time

September 16, 2024 by 10 Comments

For hackers of a certain age, the warbling of an analog modem remains something of a siren song. Even if you haven’t heard it in decades, the shrill tones and crunchy static are like a time machine that brings back memories of a bygone era. Alien to modern ears, in the 1980s and 90s, it was the harbinger of unlimited possibilities. An audible reminder that you were about to cross the threshold into cyberspace.

If you can still faintly hear those strangely comforting screeches in the back of your mind, the JawnCon 0x1 badge is for you. With a row of authentic vintage red LEDs and an impeccably designed 3D-printed enclosure, the badge is essentially a scaled-down replica of the Hayes SmartModem. But it doesn’t just look the part — powered by the ESP8266 and the open source RetroWiFiModem project, the badge will allow attendees to connect their modern computers to services from the early Internet via era-appropriate AT commands while they’re at the con.

Retrocomputers are fun, but ultimately limited in capability compared to modern hardware. One popular pursuit to rectify this is the connection of early home computers to the Internet. To that end, [que] built the Retromodem for the Commodore 64.

The build starts with a case from an Intel 14.4 modem. A little fast for the Commodore 64 era, but anachronism is charming when done tastefully. Inside is an Arduino with an ethernet module to handle the heavy lifting of carrying packets to the outside world.  [que] took the time to wire up status LEDs for the proper vintage look, which really adds something to the project. They switch on and off to indicate the various settings on the modem – it’s great to see in the video below the break the “HS” LED light up when the baud rate is changed to a higher speed.

The project implements most of the Hayes command set, so you can interface with it over a serial terminal just like it’s 1983. [que] doesn’t go into too many details of how it’s all put together, but for the experienced code warrior it’s a project that could be whipped up in a weekend or two. For a more modern take, perhaps you’d like to hook your C64 up over Wifi instead?
