Hackaday Europe 2025: Workshops And More Speakers

February 26, 2025 by Elliot Williams No comments

We’re proud to announce the last round of speakers, as well as the two workshops that we’ll be running at 2025 Hackaday Europe in Berlin on March 15th and 16th — and Friday night the 14th, if you’re already in town.

The last two years that we’ve done Hackaday Europe in Berlin have been awesome, and this year promises to keep up the tradition. We can’t wait to get our hands on the crazy selection of SAO badge addons that are going to be in each and every schwag bag.

Tickets for the event itself are going fast, but the workshop tickets that go on sale at 8:00 AM PST sell out even faster. And you need the one to enjoy the other, so get your tickets now!

February 18, 2025 by Elliot Williams 1 Comment

If you’ve been waiting for news from our upcoming Hackaday Europe event in March, wait no longer. We’re excited to announce the first slice of our wonderful speakers lineup! Get your tickets now,

Hackaday Europe is going down again in Berlin this year on March 15th and 16th at MotionLab. It’s Hackaday, but in real life, and it’s too much fun. The badge is off-the-scale cool, powered by the incredible creativity of our community who entered the Supercon SAO contest last fall, and we’re absolutely stoked to be tossing the four winning entries into your schwag bag in Europe.

If you already know you’ll be attending and would like to give a seven-minute Lightning Talk on Sunday, we’re also opening up the call for talks there. Tell us now what you’d like to talk about so we can all hear it on Sunday morning.

We’re looking forward to the talks and to seeing you all there! We’re getting the last few speakers ironed out, have a keynote talk to announce, and, of course, will open up workshop signups. So stay tuned! Continue reading “Hackaday Europe 2025: Speakers, Lightning Talks, And More!” →

Supercon 2024: Joshua Wise Hacks The Bambu X1 Carbon

January 29, 2025 by Elliot Williams 36 Comments

Bambu Labs have been in the news lately. Not because of the machines themselves, but because they are proposing a firmware change that many in our community find restricts their freedom to use their own devices.

What can be done? [Joshua Wise] gave a standout talk on the Design Lab stage at the 2024 Hackaday Superconference where he told the tale of his custom firmware for the Bambu X1 Carbon. He wasn’t alone here; the X1 Plus tale involves a community of hackers working on opening up the printer, but it’s also a tale that hasn’t ended yet. Bambu is striking back.

Hackaday Europe 2025 Tickets On Sale, And CFP Extended Until Friday

January 14, 2025 by Elliot Williams 6 Comments

We’re opening up shop for Hackaday Europe, so get your tickets now! We’ve managed to get the ticket price down a bit this year, so you can join in all the fun for $145. And if you’re reading this right now, snap up one of the $75 early bird tickets as fast as you can.

Hackaday Europe is going down again in Berlin this year, on March 15th and 16th at MotionLab. It’s going to be a day and a half of presentations, lightning talks, badge hacking, workshops, and more. This is where Hackaday hangs out in person, and it’s honestly just a great time – if your idea of a great time is trading favorite PCB design tricks, crafting crufty code, and generally trading tales of hardware derring-do.

In short, it’s the best of Hackaday, live and in person. Throughout the weekend, all the meals are catered, we’ve got live music at night, and the soldering irons will be warmed up for you. It’s going to be great!

If you’re in town on Friday the 14th, we’ll be meeting up in the evening to get together over some pre-event food and drink, sponsored by Crowd Supply. It’s a nice opportunity to break the ice, get to know the people you’re going to be spending the next 48 hours with, and just mingle without missing that great talk or wonderful workshop.

Clever PCBs Straighten Out The Supercon SAO Badge

January 13, 2025 by Tom Nardi No comments

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.

2025 Hackaday Europe CFP: We Want You!

December 10, 2024 by Elliot Williams 13 Comments

Hackaday’s Supercon is still warm in our hearts, and the snow is just now starting to fall, but we’re already looking forward to Spring. Or at least to Hackaday Europe, which will be taking place March 15th and 16th in Berlin, Germany.

Tickets aren’t on sale yet, but we know a way that you can get in for free.

Call for Participation

What makes Hackaday Europe special? Well, it’s you! We’re excited to announce that we’re opening up our call for talks right now, and we can’t wait to hear what you have to say. Speakers of course get in free, but the real reason that you want to present is whom you’re presenting to.

The Hackaday audience is interested, inquisitive, and friendly. If you have a tale of hardware, firmware, or software derring-do that would only really go over with a Hackaday crowd, this is your chance. We have slots open for shorter 20-minute talks as well as longer 40-minute ones, so whether you’ve got a quick hack or you want to take a deep dive, we’ve got you covered. We especially love to hear from new voices, so if you’ve never given a talk about your projects before, we’d really encourage you to apply!

Here is last year’s lineup, if you’re wondering what goes on, and if your talk would fit in.

The Badge Hacks Of Supercon

November 9, 2024 by Elliot Williams 4 Comments

We just got home from Supercon and well, it was super. It was great to see everyone, and meet a whole bunch of new folks to boot! The talks were great, and you can see a good half of them already on the Hackaday YouTube channel, so for that you didn’t even have to be there.

The badge hacks were, as with most years, out of this world. I’ll admit that my cheeks were sore from laughing so much after emceeing it this year, due in no small part to two hilarious AI projects, both of which were also righteous hacks in addition to full-on comedy routines. A group of six programmers got all of their hacks working together, and the I2C-to-MQTT bridge had badges blinking in sync even in the audience. You want blinkies? We had blinkies.

But the hack that warmed everyones’ hearts was “I figured it out” by [Connie]. Before this weekend, she had never coded MicroPython and didn’t know anything about I2C. But yet by Sunday afternoon, she made a sweet spiral animation on the LED wheel, and blinked the RGBs in the touchwheel.

What I love about the Hackaday audience is that, when the chips are down, someone doing something new for the first time is valued as much as some of the more showy work done by more experienced programmers. Hacking is also about learning and pushing out boundaries after all. The shouts for “I figured it out” were louder than any others in the graphics hacks category, it took home a prize, and I was smiling from ear to ear.

Hackaday can learn from this too. [Connie]’s hack definitely shows the need for another badge-hack category, first timers, because we absolutely should recognize first tries. There was also a strong petition / protest from people who had worked new hacks onto previous year’s badges – like [Andy] and [koppanyh]’s addition of bit-banged I2C to the Voja 4 badge from two years ago, and [Instant Arcade]’s Polar Pacman, which he named “Ineligible for this Competition” in protest. Touche.

We’re stoked to learn new things, see new hacks, and basically just catch up with everything folks did over the weekend. We can’t wait to see what you’re up to next year!
