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.

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!

(C3P0 add-on by [kuro_dk] and Cyclops by [Simenzhor] not included.)

The third and final round of the 2024 Supercon talks announcements brings us to the end, and the full schedule is now up on Hackaday.io.

With Supercon just a couple weeks away, we hope you have your tickets already! Stay tuned tomorrow for a badge reveal.

(Go get your tickets already. And if you’ve got ’em, see you soon!)

More than a couple folks have written us saying that their entries into the Supercon Add-On Contest got caught up in the Chinese fall holidays. Add to that our tendency to wait until the last minute, and there still more projects out there that we’d like to see. So we’re extending the deadline one more week, until October 22nd.

If you’re just tuning in now, well, you’ve got some catching up to do. Supercon Add-Ons are another step forward in the tradition of renaming the original SAO. One of our favorite resources on the subject comes from prolific SAO designer [Twinkle Twinkie], and you can even download PCB footprints over there on Hackaday.io.

Don’t know why you want to make an SAO?  Even if you’re not coming to Supercon this year? Well, our own [Tom Nardi] describes it as a low barrier to entry, full-stack hardware design and production tutorial. Plus, you’ll have something to trade with like-minded hardware nerds at the next con you attend.

We’ve already seen some killer artistic entries, but we want to see yours! We know the time’s tight, but you can still get in a last minute board run if you get started today. And those of you who are sitting at home waiting for boards to arrive, wipe that sweat from your brow. We’ll catch up with you next Tuesday!

It’s honestly amazing the range of fascinating talks we have lined up for this year’s Supercon. From art robots that burp and belch to gliders returning from near-space, from hardcore DSP to DIY PCBs, and sketching with machines, Hackaday’s Supercon is like nothing else out there.

And in case you’re already coming, you don’t have a talk slot reserved, but you’ve still got something that you want to say, please sign yourself up for a Lightning Talk! In the spirit of the Lightning, we’ll be taking submissions up to the absolute last minute, and we will fit in as many short talks as possible, but when it does fill up, we’ll be giving priority to those who got in first.

We’ve got one more speaker announce coming up, and of course our keynote speaker and the badge reveal. Supercon will sell out so get your tickets now before it’s too late. So without further ado, here is our next round of stellar speakers!

[If you read this far, you probably want tickets. Just sayin’.]

Supercon is the Ultimate Hardware Conference and you need to be there! We’ve got a stellar slate of speakers this year — way too many to feature in one post. So here’s your first taste, and a reminder that Supercon will sell out so get your tickets now before it’s too late.

In addition to the full-length talks, we’ve got a series of Lightning Talks, so if you want to share seven minutes’ of insight with everyone there, please register your Lightning Talk idea now.

But Supercon has a lot more than just talks! The badge heavily features Supercon Add-Ons, and we want to see the awesome SAOs you are working on. There will be prizes, and we’ll manufacture four of our favorite designs in small batches for the winners, and make a full run for Hackaday Europe in 2025. Want to know more about SAOs? They’re the ideal starter PCB project.

If you are a fan of interesting display technology, you definitely won’t want to miss Supplyframe’s DesignLab mini-museum of odd and interesting displays.

Of course, there will be workshops. We haven’t announced them yet, but swing by Hackaday on Tuesday the 24th at 8 AM PST for our Gigantic Workshop Reveal and Ticket Sale!

So stay tuned for that announcement, the full details on the badge, and of course the remaining speakers.

See you in November at Supercon!

[If you read this far, you probably want tickets. Just sayin’.]

Tickets for the 2024 Hackaday Supercon are on sale now! Go and get yours while they’re still hot. True-Believer Tickets are half-price at $148 (plus fees), and when that pile of 100 is gone, regular admission is $296 (plus fees).

Come join us on November 1st-3rd in sunny Pasadena, CA, for three days of talks, demos, badge hacking, workshops, and the sort of miscellaneous hardware shenanigans that make Hackaday Hackaday! If you’ve never been to a Supercon, now is the best time to check that off your bucket list. And if you’re a seven-time veteran, we’re stoked to see you again. Supercon is like a year’s worth of posts in one weekend. You don’t want to miss it.

Friday, November 1st, is our chill-out day. You can roll in as soon as the doors open in the morning, get your badge and some bagels, and get down to hacking. Or you can start socializing early. Or, as it almost always happens, both at once. We’ll have food and music and even a few workshops, but for the most part, Fridays are what you all make of them. And we love it that way.

Talks start up on Saturday on both stages, along with the soldering contest and an alley full of hackers. We’ll close out the evening with a special celebration, but more on that in a minute.

On Sunday, in addition to the usual slate of talks, we’ve set aside a big block of time for Lightning Talks. These are seven-minute quickies where you get to tell the bigger Hackaday community what you’re up to. A short talk like this forces you to condense the story down to its essence while giving tons of people their fifteen minutes of fame in half the time! If you’ve got a Lightning Talk that you’d like to present, let us know! We’ll try to fit in everyone we can.

Wrapping up Sunday evening, we’ll give you a chance to show off whatever badge hacks you’ve been working on over the weekend. We love the badge hacking demo because it allows us to see a wide (and wild) range of projects, all of which were put together in record time. Whether funny, flashy, or phenomenal, we want to see what you’ve been up to.

Supercon Add-Ons

It’s still way too early to let the badge cat out of the bag, but we’ll give you a clue. This year centers around the shitty Supercon Add-On. We want you to make your own fun badgelets to show off and share, so we’re offering three special prizes and much limited-edition schwag for honorable mentions.

Or, if you want to make it more interesting, the six-pin SAO standard has both I2C lines and a pair of GPIO pins, and we don’t see those taken advantage of nearly enough in the wild. If you’re already onto your second or third SAO design, why don’t you pay attention to the connectivity in this design?

Next week, we’ll release the full specs, rules, and regulations. Until then, start brainstorming up six-pin SAO designs. Again, we’re not saying that you’ll need to make use of the I2C pins, but we’re saying that we’ll be running some tutorial articles about SAO design in the very near future. Here’s [Arya]’s SAO design primer from two Supercons past if you want to get a head start.

Come Join Us!

If you are Hackaday, you really want to make it to Supercon if you can, and we want to see you there. You’re all a great crowd, and the small size and relaxed venue makes for about the highest signal-to-noise ratio around! We’ll be releasing the schedule as it firms up over the next couple weeks, and until then, you have a chance to get a discount ticket if you move quickly. Stay tuned, and act fast!
