Supercon 2025 Badge Gets Vintage Star Trek Makeover

There are still a few days before the doors open on this year’s Hackaday Supercon in Pasadena, but for the most dedicated attendees, the badge hacking has already begun…even if they don’t have a badge yet.

By referencing the design files we’ve published for this year’s Communicator badge, [Thomas Flummer] was able to produce this gorgeous 3D printed case that should be immediately recognizable to fans of the original Star Trek TV series.

Metal hinge pin? Brass inserts? Scotty would be proud.

Although the layout of this year’s badge is about as far from the slim outline of the iconic flip-up Trek communicator as you can get, [Thomas] managed to perfectly capture its overall style. By using the “Fuzzy Skin” setting in the slicer, he was even able to replicate the leather-like texture seen on the original prop.

Between that and the “chrome” trim, the finished product really nails everything Jadzia Dax loved about classic 23rd century designs. It’s not hard to imagine this could be some companion device to the original communicator that we just never got to see on screen.

While there’s no denying that the print quality on the antenna lid is exceptional, we’d really like to see that part replaced with an actual piece of brass mesh at some point. Luckily, [Thomas] has connected it to the body of the communicator with a removable metal hinge pin, so it should be easy enough to swap it out.

Considering the incredible panel of Star Trek artists that have been assembled for the Supercon 2025 keynote, we imagine this won’t be the last bit of Trek-themed hacking that we see this weekend — which is fine by us.

Announcing The 2025 Hackaday Superconference Communicator Badge

It’s the moment you hard-core hardware nerds have been waiting for: the reveal of the 2025 Hackaday Supercon Communicator Badge. And this year, we’ve outdone ourselves, but that’s thanks to help from stellar collaboration with folks from the community, and help from sponsors. This badge is bigger than the sum of its parts, and we’ve planned for it to be useful for you to hack on in the afterlife. Indeed, as always, you are going to be the final collaborator, so we can’t wait to see what you’ll do with it.

We’re going out – wide out – on a limb and trying to create a dense mesh network of badges talking to each other at Supercon. It’s going to be like a badge-hosted collection of chat rooms, as connected as we can make them without talking over each other.

You look up a topic, say Retro Computing or SAO trading, punch in the channel number on the numpad, and your badge starts listening to everything going on around that topic. But they also listen to everything else, and repeat anything they hear on to their neighbors. Like IRC, but LoRa.

Plenty Of LEDs And Useful Too: The 2025 DORS/CLUC Badge

It’s always nice to see new developments in the world of electronic badges, and while there are events and badge teams pushing the technological envelope there’s still plenty of scope for innovation without too many exotic parts. This year’s DORS/CLUC open source conference in Croatia has just such a badge, with a large alphanumeric LED display as well as USB and an NFC reader. During the conference it displayed the user’s name and could be used in an NFC-based game, but it’s also designed to be used as a general purpose notification device afterwards.

The write-up is familiar to anyone who has been involved with badge production, a tale of long soldering sessions as missing components had to be added later, and of last minute firmware flashing. The heart of the machine is an STM32L073, with an IS31FL3731 LED matrix driver chip and an ST25R3916 for the NFC. All the files can be found in a GitLab repo, and there’s a video below the break showing it all in action.

Track Your Circuits: A Locomotive PCB Badge

This fun PCB from [Nick Brown] features a miniature railroad implemented with 0805-sized LEDs. With an eye towards designing his own fun interactive PCB badge, the Light-Rail began its journey. He thoroughly documented his process, from shunting various late-night ideas together to tracking down discrepancies between the documentation of a part and the received part.

Clever PCBs Straighten Out The Supercon SAO Badge

When we decided that Simple Add-Ons (SAOs) would be the focus of Supercon 2024, it was clear the badge would need to feature more than just one or two of the requisite connectors. We finally settled on six ports, but figuring out the geometry of getting all those ports on the badge in such a way that the SAOs wouldn’t hit each other was a bit tricky. In early concept drawings the badge was just a big rectangle with the ports along the top, but it was too ugly.

In the end we went with a somewhat organic design — an electronic “flower” with the radially arranged SAOs forming the petals, but this meant that that none of the SAOs were in the traditional vertical orientation. Luckily, [Adrian Studer] designed a couple of PCBs that not only resolve this issue, but add a seventh SAO port for good measure.

In the project repository you’ll find two PCB designs. The first, “SAO Up” is essentially a little arm that turns the SAO port 90 degrees. This doesn’t exactly get them vertical, in fact, whether or not the new orientation is actually an improvement for the top two SAOs is perhaps debatable. But it definitely helps on the lower SAOs, which are essentially upside down in their original configuration.

The real star of the show is “SAO Bridge”, a wavy board that connects across the two midline SAO ports on the Supercon badge and turns it into a set of three (nearly) horizontal connectors across the front. The center port is particularly helpful in that it gives you a place to put unusually wide SAOs.

As a reminder the Supercon SAO badge, and the winners of the 2024 SAO Contest, will be making the trip across the pond for Hackaday Europe in just a few months. That means you’ve still got plenty of time to have a few of these CERN-OHL-P licensed boards made up.

The 2024 Hackaday Supercon SAO Badge Reveal

We’ve been hinting at it for a few months now, running a series of articles on SAOs, then a Supercon Add-On Challenge. We even let on that the badge would have space for multiple SAOs this year, but would you believe six?

Way back in 2017ish, Hackaday’s own [Brian Benchoff] and the [AND!XOR] crew thought it would be funny and useful to create a “standard” for adding small custom PCB art-badges onto bigger conference badges. The idea was to keep it quick and dirty, uncomplicated and hacky, and the “Shitty” Add On was born. The badge community took to this like wildfire. While the community has moved on from the fecal humor, whether you call these little badgelets “SAOs”, “Simple Add-Ons”, or even “Supercon-8 Add Ons”, there’s something here for everyone. So if you’ve already got some SAOs in a drawer, bring them to this year’s Supercon and show them off!

The JawnCon 0x1 Badge Dials Up A Simpler Time

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.
