This year we challenged the Hackaday community to develop Shitty Simple Supercon Add-Ons (SAO) that did more than just blink a few LEDs. The SAO standard includes I2C data and a pair of GPIO pins, but historically, they’ve very rarely been used. We knew the talented folks in this community would be able to raise the bar, but as they have a tendency to do, they’ve exceeded all of our expectations.

As we announced live during the closing ceremony at the 2024 Hackaday Supercon, the following four SAOs will be put into production and distributed to all the attendees at Hackaday Europe in Spring of 2025.

Best Overall: SAO Multimeter

For the “Best Overall” category, we only intended to compare it with the other entries in the contest. But in the end, we think there’s a strong case to be made that [Thomas Flummer] has created the greatest SAO of all time. So far, anyway.

This add-on is a fully functional digital multimeter, with functions for measuring voltage, resistance, and continuity. The design is a pure work of art, with its structure combining stacked PCBs and 3D printed parts. There’s even tiny banana plugs to connect up properly scaled probes. Incredible.

In the documentation [Thomas] mentions there are additional functions he didn’t have time to include in the firmware, such as modes to analyze the I2C and GPIO signals being received. Now that it’s been selected for production, we’re hoping he’ll have the time to get the code finished up before its European debut.

Fun: Etch sAo Sketch

This SAO recreates the iconic art toy in a (hopefully) non-trademarked way, with a 1.5″ inch 128 x 128 grayscale OLED display and a pair of trimpots capped with 3D printed knobs. Drawing is fun enough, but the nostalgia really kicks in when you give it a good shake — the onboard LIS3DH 3-axis accelerometer picks up the motion and wipes the display just like the real thing.

Created by [Andy Geppert], this SAO isn’t just a pretty face. Flipping it over shows an exceptionally clever technique for connecting the display board to the main PCB. Tiny metal balls (or “alignment spheres” if you want to get fancy) mate up with the mounting holes on the OLED board and center it, and a touch of solder locks it all in place.

Fine Art: Bendy SAO

While this wacky, waving, inflatable, arm-flailing SAO might look like the sort of thing that would be outside of a used car dealership, but creator [debraansell] managed to shrink it down so the point that it’s reasonable to plug into your badge. More or less.

There are several fascinating tricks at work here, from lighting the PCB from the back using side-firing LEDs to the integrated slip rings. If this one didn’t look so good, it would have been a strong contender for the “Least Manufacturable” Honorable Mention.

Functional: Vectrex SAO

Creating a replica of the Vectrex at SAO scale would have been an impressive enough accomplishment, but [Brett Walach] took this one all the way and made it playable.

The display is a 7 x 10 Charlieplexed LED matrix, while the “joystick” is implemented with a 1-button capacitive touch sensor. A PIC16F886 microcontroller runs the simplified version of Scramble, and there’s even a speaker for era-appropriate audio.

But that’s not all! This SAO was also designed to be hacked — so not only is all the hardware and software open source, but there’re various jumpers to fiddle with various settings and an I2C control protocol that lets you command the action from the badge.

Honorable Mentions

As usual, this contest had several Honorable Mentions categories — while we would have loved to put all of these SAOs into production, there’s only so much we can do before now and Spring.

[Jeremy Geppert]’s SAO LoRa Walkie Talkie was a judge favorite, for its simple good looks and the extra functionality that it brings to the table. [Scorch Works]’s SAO Infinity Mirror was absolutely beautiful to see in person, and makes a fantastic display when many of them get together. And [MakeItHackin]’s Skull of Fate SAO not only looked super when its eyes scan the room, but it could read your future as well!

Best Communication:

Using I2C to get SAOs to talk to the badge (or each other) was a big part of this contest, but we were also on the lookout for entries which helped facilitate badge-to-badge communications.

The Badge Tag NFC SAO from [Thomas Flummer] is a perfect example of both — it uses the NXP NTAG I2C Plus to provide 2K of read-write storage that can be accessed either internally through the I2C bus by the badge, or externally by an NFC device such as a smartphone. Modeled after a traditional conference name tag, this SAO was designed to make it easier for sharing your contact info with others during a busy con.

Infrared Communication SAO by [Alec Probst] brings infrared communications to the party, while looking like a classic TV remote. Though the original idea was to get this working in conjunction with the badge to act as a sort of TV-B-Gone, it ended up being used as part of a laser tag game during Supercon.

The GAT Nametag SC8 from [true] tackles communication on a more human level by providing a digital name tag for your badge. This compact board’s secret trick is the ability to make sure your name is legible no matter what its orientation thanks to a LIS2DW12 accelerometer that can detect the SAO’s orientation relative to the ground. RGB LEDs catch the viewer’s eye, but it’s the incredible firmware with seemingly endless options for text styling and tweaks that really set this build apart.

Light Show:

There’s little question that Featuring You! from [Nanik Adnani] is a perfect entry for this category. Nominally, it’s a little arrow you can write your name on and use a name tag. But power it up and you can dazzle anyone standing too close with its array of marching white LEDs. In a particularly nice touch, the circuit is implemented with only discreet components — no microcontroller.

The reDOT_RGB from [Alex] is a tiny 5×7 RGB LED matrix with a minuscule ATtiny816 MCU around the back to control the show. At just 8 x 11 mm, it’s hard to overstate just how tiny this SAO is.

While on the subject of tiny boards, the
Persistence of Vision POV Display is another entry not much larger than the SAO connector itself. Using a row of five tiny white LEDs and a ADXL345 accelerometer, [Michael Yim] is able to write text in mid-air thanks to the gullibility of the human eye.

Least Manufacturable:

Simple Add-Ons are essentially an art form, so it’s not surprising to find that they don’t often lend themselves to mass production. Several of the entries this yeah would be a real challenge to make in large numbers, but the one that really keeps us up at night is the ultra tiny smart SAO from [Alex].

This board is designed to fit inside the space between four header pins. Thanks, but no thanks.

Raising the Bar

Our hope this year was to elevate the Simple Add-On from a decorative piece of flair to something functional, and potentially, even useful. The results were incredible, and while we can only pick four winners this time around, every entry helped push the state-of-the-art forward in its own way. It’s hard to imagine how the SAO envelope can be pushed any further, but we can’t wait to find out.

The 2024 Hackaday Supercon is on in Pasadena, but if you couldn’t make it to sunny California this year, don’t worry. We’ve got a live streams of the main stage talks, and all of the second track talks are being recorded and will be put up on the YouTube channel after the con.

If you’re watching from home and want to join the conversation, today might be a good time to join the official Hackaday Discord server.

Even in the advanced world of 2024, robots are still better in science fiction than in reality. Star Trek gave us the erudite and refined Data, Rogue One gave us the fierce yet funny K-2SO, and Big Hero 6 gave us the caring charmer named Baymax. All these robots had smarts, capability, and agency. More than that, though—they were faithful(ish) companions to humans, fulfilling what that role entails.

The thing is, we’re not gonna get robots like that unless somebody builds them. [Angela Sheehan] is a artist and an educator, and a maker—and she’s trying to create exactly that. She came down to the 2023 Hackaday Supercon to tell us all about her efforts to create cuddly companion bots for real.

Beep Boop

You might remember Angela from her 2019 Supercon costume—she showed up dressed as a color-changing fairy. In fact, she has dabbled in all kinds of fields, which has given her a broad skillset applicable to creating companion bots. She’s done lots of costuming and cosplay over the years, she’s worked in product design, and she brands herself a bit of a fashion hacker. These skills might not be particularly relevant to building a high-speed industrial robot arm to perform 2000 welds an hour. However, they come in absolute clutch when you’re trying to build a robot that acts as a soft, cuddly companion. She notes that she was inspired to create her own companion bots by the work of others formerly showcased by Hackaday—you might remember work in this field from Alex Glow and Jorvon Moss.

Angela’s talk soon tackles the elephant in the room—from the drop, you’ve probably been wondering about the cute critter perched on her shoulder. The long-tailed creature is named Nova, and she’s remarkably friendly and soothing once you get to know her.

Development took some time, with Angela doing lots of research and development to create the Nova we see today. “I actually did a lot of the prototyping and field testing for this bot in the library makerspace that I work at,” she explains. “It was great to see people who don’t know the inside and out of technology interact with [Nova] and I could pinpoint the moment that she became alive to people.” The bot got quite a response, transcending the level of basic machine to something a little more. “People wanted to come in and visit her and pet her,” says Angela. “That was such a powerful moment… that happened as soon as I started putting a face on her.” Angela doesn’t just tell the tale—during the talk, she passes Nova to the audience so they can interact with her up close. She explains that this is something that she does regularly—and we get to see photos of the lovely interactions Nova has had with dozens of smiling, happy people.

The face, though, was perhaps most crucial—as is the case for any anthropomorphic character. She took inspiration from Toothless from How To Train Your Dragon, using a stuffed toy as reference. Initial attempts weren’t particularly satisfying though, so she learned 3D sculpting for a further attempt in clay. Feedback from Twitter helped her develop the face further into the Nova we see today. The eyes were sourced from an Etsy supplier specializing in doll eyes. Angela notes there’s some magic there—when backlit with LEDs, switching them on and off can create a really believable blink pattern that feels super realistic. “What are those elements that make it feel alive?” Angela muses. “There are just little pieces of the psychology of it that you can dial into and you can make something that feels very alive.”

The talk then covers the rest of the design that helps create the “illusion of life.” Angela explains using servos and a robot gripper mechanism to flap the wings, and dialing in the motion so it felt as authentic as possible. She also covers robustness, designing “cuddle-worthy” bodies, and the value of designing for modularity. There’s also a useful discussion about how to make these builds more accessible, including useful starting points like which microcontroller and code platforms are good to use.

Even better, we get a look into the companion bot community, and we learn about the emotional impact these robots can have. Sometimes that’s intentional, other times, it’s down to a happy accident. “There is an unintended effect with [Nova’s] servos, that it feels like a purr,” says Angela. “It’s very comforting right on your shoulder, and I was thinking maybe I should try and insulate it a little bit, but actually people love it.”

Fundamentally, companion bots are a bit like virtual reality. We’ve seen a ton of products make big promises over the years, but we’ve never seen a killer app. However, as [Angela] demonstrates, it’s very possible to create something very real and very lovable if you pay attention to the right things. Perhaps it’s the personal touch that makes DIY companion bots so seemingly lifelike in a way that Furby never was.

In any case, if you’ve ever wanted a robot companion of your very own, there’s no reason you can’t start building your own. With maker skills, enthusiasm, and the will to succeed, you can create a fun and cuddly robot critter that has that magical spark of life.

If you’re hear a rushing noise, don’t be alarmed — that’s just the rapidly approaching 2024 Hackaday Supercon. As hard as it is to believe, a whole year has gone by, and we’re now just a few days away from kicking off our annual hardware hacking extravaganza in Pasadena. Tickets just sold out over the weekend — thank you procrastinators!

For those of you who have tickets to join us this weekend, we’ve got a few last minute announcements and bits of information we wanted to get out to you. As a reminder, you can find the full schedule for all three days on the official Supercon site.

New Events Added!

For those who’ve attended a Supercon before, you know we like to cram as much content as we can into the weekend. But there’s always room for more, and this year we’ve managed to squeeze in a couple extra activities that we’re very excited about.

Halloween Hacker Happy Hour

It just so happens that Halloween is the night before Supercon officially kicks off, and that seemed like too good of an opportunity to pass up. So we’ll be throwing a pre-event party at the nearby KingsRow Gastropub where costumes and all manner of blinking LEDs are very much encouraged. Officially we’ll be hanging out from 7:00 to 10:00 PM, but don’t be surprised if you find yourself still talking to Hackaday folks at last call.

You don’t need tickets for this event, but we’d like to have a rough head count, so if you could RSVP through Eventbrite we’d appreciate it.

Tina’s Junk Challenge

We’ve always wanted to introduce some kind of swap meet aspect to Supercon, but the logistics have always been a challenge. This year though, we’re finally going to get the chance to test out the idea. Former DesignLab Resident Tina Belmont is in the process of moving out of the country and needs to find a new home for her electronic bric-a-brac.

Everything is free, so attendees are encouraged to take anything they think they can make use of. Naturally, an influx of interesting hardware could provide for some very unique badge hacking possibilities. If we can get enough people to graft these second-hand components onto their badges, we just might be able to turn it into a proper category come Sunday night.

A table where folks can offload their electronic bits and bobs has worked well at other hacker cons, so we’re eager to see how it goes at Supercon. If this is something you’d like to see more of, or would potentially like to participate in next year, let us know.

Krux’s Side Quests

Let’s be honest, most of us are already taking our marching orders from the computer in one way or another. So why not turn it into a fun interactive game?

The idea is simple: use the mysterious retrocomputer oracle, and it gives you a quest. Maybe you’ll have to find a hidden item, or solve a riddle. Krux has a run a variation of this game at Toor Con in the past, but the challenges spit out by the computer this time will be tailored to Supercon.

Windows Through Wires Exhibition

You may recall that we asked the Hackaday community if they had any unusual display technology they’d like to show off during Supercon as part of an exhibit.

Well, as you might have imagined, the response was incredible. From gorgeous vintage pieces to completely custom hardware, there’s going to be a wide array of fascinating hardware for attendees to study up-close.

While getting a chance to see various display technologies throughout the years would have our attention as it is, what’s really exciting is that many of the custom-built devices in the exhibit are either projects hosted on Hackaday.io or ones that we’ve covered at some point on the front page.

Considering how gorgeous some of them have looked in photographs, we’re eager to drool over them in the real world — and we bet you are to.

Workshop Technical Difficulties

Hopefully we’ve provided enough good news that we can slip in a bit of the bad. Unfortunately, we’ve had to cancel the “Hands on with an Electron Microscope” workshop that was to be hosted by Adam McCombs and Isabel Burgos. Everyone with tickets will of course be getting a refund, and you should be receiving an email to that effect shortly if you haven’t already.

While we’re just as disappointed by this news as you are, it’s one of those situations where there simply weren’t any good solutions. Long story short, the scanning electron microscope that was small enough to bring to Supercon is down, and there’s just not enough time to get it up and running at this point. An attempt was made to find another small-ish electron microscope on short notice but…well, that’s just as tricky to pull off as it sounds.

Send Us Your Lightning Talks!

To end this update on a high note, we want to remind everyone that this year we’ll once again be going Lighting Talks on Sunday morning. If you’ve never given a talk before, the shorter seven minute format is perfect for getting your feet wet. Or maybe you’ve got something you want to talk about that doesn’t take a whole hour to explain. Either way, the Lightning Talks are a great way to share what your passionate about with the Supercon audience.

If you’d like to give a Lightning Talk, simply fill out this form. You can upload slides if you’ve got them, but they aren’t strictly necessary.

The Vectrex was a unique console from the early 1980s. Developed by a company you’ve probably never heard of—Smith Engineering—it was put into production by General Consumer Electronics, and later sold by Milton Bradley. It was an outright commercial failure, but it’s remembered for its sharp vector display and oddball form factor.

The Vectrex was intended for tabletop use in a home environment. However, [Jeroen Domburg], also known as [Sprite_tm], decided to set about building a portable version. This wasn’t easy, but that just makes the development process a more interesting story. Thankfully for us, [Sprite_tm] was kind enough to tell the tale at the 2023 Hackaday Supercon.

Vectorlicious

[Sprite] starts by introducing the audience to the Vectrex, just to make sure everyone understands what was special about this thing. For comaprison’s sake, he lines it up against its contemporaries. Back in the early 1980s, the Atari 2600 and the Intellivision had incredibly low resolution video output with big ugly pixels. In contrast, the Vectrex could draw clean, sharp lines with its inbuilt vector-style display.

Basically, instead of coloring in individual pixels, the Vectrex instead drew lines from point to point on the screen. It was an entirely different way of doing graphics—fast, tidy, and effective—and it was popular in early video arcade games, too. Some Vectrex games even came with plastic overlays to create the impression of color on the screen. Unlike pixel displays, though, this technology didn’t really scale well to prettier, more lifelike graphics. Thus after the Vectrex, no other mainstream consoles adopted this technique.

From there, [Sprite_tm] walks the audience through the hardware of the Vectrex. The architecture is fairly simple, based around a 68A09 CPU, which is a Motorola CPU with some improvements over the earlier 6502. It’s paired with some ROM, RAM, and I/O glue logic, and it loads its games off cartridges. Then there’s the audio hardware, a digital-to-analog converter for video output, and all the subsequent analog electronics for driving the vector CRT display.

Unlike a modern console, what’s inside the box is no secret. Datasheets and full schematics are publicly available that lay out exactly how the whole thing works. This is hugely valuable for anyone looking to repair a Vectrex—or make a portable one. You don’t need to reverse engineer much, since it’s all laid out for you. Indeed, as [Sprite_tm] notes, a replica motherboard already exists that lets you play Vectrex games on an oscilloscope’s XY input.

Building the Portable

Some people have built small Vectrexes before, by going the emulator route with a Raspberry Pi and a small LCD display. [Sprite] wasn’t a fan of this route, as modern pixel LCDs make for jagged diagonal lines because they’re not proper vector displays like the original Vectrex CRT. Thus, to build a more authentic portable Vectrex, [Sprite_tm]’s build needed certain parts. On top of replicating the CPU and logic of the Vectrex, he needed to find a small CRT that operate as a proper vector display. Plus, he wanted to build something properly portable—”I wanna sit on the bus and then whip it out and play it,” he explains.

Obviously, finding a suitable CRT was the first big hurdle to clear. [Sprite_tm] mused over using a tube from a Sony Watchman handheld portable TV, but decided against it. He notes that these are fairly rare and valuable, and he didn’t want to destroy one for his project. But he still needed a small CRT in a practical form factor, and he found the perfect donor. In the 90s, LCDs were pretty crap and expensive, so apartment video intercoms relied on CRTs instead. Now, these systems are all largely defunct, and he notes you can find old examples of these answerphones for a few dollars online.

Of course, these answerphone CRTs weren’t designed for vector operation. However, [Sprite_tm] teaches us how you can convert one to draw straight lines on command instead of scanning like a TV. You can get legit vector operation just by squirting the right voltages into the deflection coils. Of course, getting it to work in practice is a lot harder than you might think, but perseverance got the job done in the end. Understanding the physics involved is useful, too, and [Sprite_tm] explains the theory with an apt comparison between coils and a pig.

From there, the talk explains how the rest of the hardware came together. [Sprite_tm] elected to stuff all the Vectrex magic into an FPGA, which felt cooler than software emulation but was more compact than using all-original chips on a replica mainboard. It lives on a custom PCB that also carries all the necessary electronics to drive the CRT in the desired vector mode.

The build also has a cartridge port for playing original Vectrex games. However, for ease of use, [Sprite] also fitted a RISC V CPU, some RAM, and a microSD card for loading ROMs for games that he doesn’t own in physical format. Everything was then wrapped up in a custom 3D-printed case that’s roughly twice as large as the Nintendo Game Boy Color in length and width—and about four times thicker.

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!

But you don’t need to bring your own SAOs. We thought that as long as we were providing six SAO ports, we’d provide you with a small starter collection: four of them, in fact. A fantastic capacitive touch wheel designed by [Todbot], a beautiful spiral petal matrix of LEDs designed by [Voja Antonic], a completely blank-slate protoboard petal, and an I2C-enabled microcontroller proto-petal.

Bringing it all together, of course, is the main badge, which sports a Raspberry Pi Pico W on the back-side, for WiFi and Bluetooth connectivity. This badge is intended to be a showcase of SAOs, and we thought that there have always been some under-explored corners of the spec. The most recent six-pin standard has power, ground, two GPIO pins, and an I2C pair. How often do we see SAOs that only use the power lines? This year, that changes!

Every GPIO pin on all six SAO slots is individually accessible, and the Pi Pico’s two hardware I2C peripheral busses are broken out on the left and right sides of the badge respectively. (Have an I2C enumeration conflict? Just move one of the offenders to the other side.) The idea here, combined with the wireless features and a trio of buttons on the front, is to give you a big sandbox to explore the possibilities of SAOs that go farther than just art.

Many Ways to Play

Straight out of the gate, the touch wheel and the LED petal matrix invite you to play with them, all the while fooling you into learning a little bit about interfacing I2C devices. You see, I2C devices have a unique address, and the rest of the functionality is handled by as if they were memory-mapped peripherals. What does this mean? If you want to ask the touch wheel where your finger is, you simply query its memory location 0. To set the LED colors, you write bytes to memory locations 15, 16, and 17 for red, green, and blue, respectively. Each spiral arm of the LED matrix petal is simply a byte in memory – write to it and the blinkies blink.

The take-home: I2C devices are fun and to play with. And when you start combining the functions of multiple SAOs, you can really start getting creative. But we’ve only scratched the surface. The I2C proto petal includes a CH32V003 chip, with its own dedicated I2C device hardware peripheral, so if you have essentially anything that you can solder to it, you can turn that into an I2C-enabled device to add to the party.

This is a multi-lingual party, though. The main badge, and all of the connection logic, runs on MicroPython. This makes it just a few lines of code to display your finger presses on the touchwheel over on the LED petal matrix, for instance, and we’ll have some demo code to ease you in. (And we’re frantically writing more!) But the I2C protoboard requires a little bit of C. If you’ve got a CH32V003 environment set up, by all means bring it – we love [CHLohr]’s CH32V003fun. We’re working on getting the badge board to program the CH32 in-situ, and we’re 99% sure we’ll have that ready by showtime. We’ll have demo code here to get you started as well. Will you program your first RISC-V chip at this year’s Supercon?

But say you don’t want anything to do with all this software? Just give me the solder! The blank-slate protoboard is for you. It breaks out the SAO lines, and gives you maximal room for creative hardware play. Heck, you could solder an LED, a resistor, and call it done. Or play around with the possibilities of the GPIOs. Low-code or no-code, the choice is yours.

Participate!

We know you’re all looking forward to getting your hands on the badge and the SAOs and getting creative. Here is the 2024 Supercon SAO Badge GitHub repository, for your perusal. All of the design files that we have are there in the hardware directory, but the code is not yet complete. If you want to design a 3D-printed case or add-on, you’ll find the vector files in PDF.

As usual [Voja] makes his circuit diagrams by hand, so you’ll find a beautifully annotated schematic that lets you know where each and every pin goes. If you’re not feeling the AA battery love, you’ll see that [Voja] has left you some pads to hook up an external power supply, for instance.

But the software is a work in progress, and in particular, we don’t know what I2C devices you’ll be bringing with you. We’re going to include as many MicroPython I2C device libraries as we can find, from OLED screens to magnetometers, and we’d like them to be on the default conference image. So if you’ve a device that you’d like us to support, either drop a link in the comments below or add the code in the libraries folder and submit a pull request! We’ll be flashing these at the absolute last minute, of course, but please get it in this weekend if you can.

Supercon!

Supercon 8’s badge is the unofficial world-record holder for the most SAO connectors on any official conference badge, but it also aspires to encourage you to play around with the functional aspects of our favorite mini-badge form factor. Heck, maybe you’ll learn a thing or two about I2C along the way? Push some GPIOs around? Or maybe you’ll just have a fun weekend with a soldering iron, some stellar talks, and some great company. Whatever it’s going to be, we can’t wait to see you all, and to see what you come up with!

If you have any questions about the badge, fire away in the comments here.

You do have your tickets already, right? See you soon!

Starting a hacker con is hardly what anyone would describe as easy — but arguably, the truly difficult part is keeping the momentum going into the second year and beyond. For the first year, you can get away with a few missed opportunities and glitches, but by the time you’ve got one event under your belt, you’ll have set the bar for what comes next. There’s pressure to grow, to make each year bigger and better than before. All the while, making sure you don’t go broke in the process. Putting on a single hacker con is an achievement in and of itself, but establishing a long-running hacker con is a feat that relatively few groups have managed to pull off.

With this in mind, the incredible success of the second annual JawnCon is all the more impressive. The Philadelphia-area event not only met the expectations of a sophomore effort, but exceeded them in pretty much every quantifiable way. From doubling attendance to providing a unique and immersive experience with their electronic badge, the team seized every opportunity to build upon the already strong foundation laid last year. If this was the make-or-break moment for the Northeast’s newest hacker con, the future looks very bright indeed.

But before setting our sights on next year, let’s take a look at some of the highlights from JawnCon 0x1. While you can watch all of this year’s talks on YouTube, the aspect of a hacker on that can’t easily be recorded is the quality time spent with like-minded individuals. Unfortunately, there’s no way to encompass everything that happened during a two-day con into a single article. Instead, this following will cover a few of the things that stood out to me personally.

If you’d like to experience the rest of JawnCon, you’ll just have to make the trip out to Philly for 2025.

Creating New Traditions

For returning attendees, certainly the most striking thing about this year’s event was simply how many people showed up. In the closing ceremonies, we learned that attendance had more than doubled since last year, and you could absolutely feel it. The rooms never felt cramped, but they certainly felt full. 

But the growth of this year’s event wasn’t limited to the ticket holders. The local chapter of The Open Organisation Of Lockpickers (TOOOL) was there, equipped with picks and transparent padlocks for anyone interested in an impromptu lesson in lockpicking. You could also try to get yourself out of a pair of handcuffs and other forms of restraints.

This year also featured a “Free Table” where attendees could leave interesting items for others. We’ve all got some piece of hardware that’s been gathering dust for just a bit too long. Maybe it was for some project that you’re no longer interested in, or you just don’t have the time to mess around with it. Instead of tossing it in the trash, a table like this is a great way to re-home some of those technical treasures.

The table was constantly being refreshed as more attendees showed up and added their contributions to the pile. There was only one rule: if your stuff was still there at the end of the con, you had to take it home. But as things started wrapping up on Saturday evening, there were just a few oddball antenna cables and a couple mystery PCBs left. It was especially gratifying to see how many reference books were picked up.

Another highlight this year was a informal competition inspired by the old IT adage that digital subscriber line (DSL)  broadband service could be run over a piece of wet string. With all the hardware necessary to establish a DSL connection on-site, attendees were invited to bring up various objects that would fill in for the telephone line. The medium that provided the fastest confirmed Internet connection would be crowned the winner.

Two pieces of spaghetti ended up taking the top spot, with a link speed of 10 Mbit. A section of carbon fiber tube — dubbed “hard-line coax” for the purposes of the competition — managed second place with around 6 Mbit. As you might expect, the failures in this competition were perhaps just as interesting as the successes. A line of “energy gel” was apparently not conductive enough, though some flickering of the indicator LEDs on the modem seemed to indicate it was close. While it came as no surprise that a line of hackers holding hands wasn’t a suitable link for the experiment, the audience did appreciate the irony that the hardware indicated it couldn’t progress past the handshaking stage of the connection.

Living History for Hackers

Attendees had already gotten a sneak peek at the JawnCon 0x1 badge a few weeks before the event, so the fact that they’d all be getting tiny modems to plug into their computers (and indeed, wear around their necks) wasn’t a complete surprise. But still, I don’t think anyone was fully prepared for what a unique experience it was really going to be.

For the younger players, there was an obvious learning curve. But the veterans in attendance were all too happy to explain the relevant AT commands and get them dialing away. Once you’d figured out how to connect up to the network and start exploring, it added a whole new dimension to the event.

Not only were there various puzzles and Capture the Flag (CTF) challenges that could be accessed through the modem, but it also acted as a gateway to games, chats, and other features that functioned within the con’s infrastructure.

For example, running a command within the modem’s onboard menu system would print the current talk taking place on the stage downstairs, and tell you who was up next.

It was actually a bit surreal. Walking around you’d come across a table of 20-somethings, all with look-alike Hayes modems plugged into their shiny new MacBooks or high-end gaming laptops. It’s hard to say how many of them came away from the event with a new respect for the old ways, but there’s no question they had learned a hell of a lot more about the early Internet than they would have from just watching a YouTube video about it.

While the badge was certainly the star of the show, there were also vintage serial terminals dotted around the chill-out area that you could interact with. By default they showed the talk schedule in a glorious shade of either amber or green, but hit a key and you’d be dumped into the terminal. Nominally, jumping on the terminals and executing various tasks was part of the CTF, but it was also a lot of fun to turn back the clock and sit down at a real serial terminal and interact with some *nix box hidden away elsewhere in the building.

Long Live the Jawn

Any event that manages to double its attendance from the previous year is clearly doing something right. But if you don’t know how to handle the growth, it can become a problem. Luckily, the JawnCon staff are on the case. It sounds like next year they may opt to use a larger space within the same building at Arcadia University. The University is a great fit for the event, so the fact that there’s room to grow is great news for everyone involved.

Of course, it takes more than simply securing a larger room every couple years to make sure an event like this stays on the right track. You also need intelligent and responsible folks at the wheel. Here again, JawnCon is well equipped for the future. The staff and volunteers that worked tirelessly behind the scenes to bring this con to life are some of the most passionate and welcoming individuals I’ve ever had the pleasure of meeting. They represent the very best qualities of hacker culture, and armed with a genuine desire to bring that sense of exploration and inclusion to the next generation, they’re the catalyst that will keep JawnCon growing and evolving over the coming years.
