2025 Hackaday Europe CFP: We Want You!

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

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!

2023 Hackaday Supercon: One Year Of Progress For Project Boondock Echo

Do you remember the fourth-place winner in the 2022 Hackaday Prize? If it’s slipped your mind, that’s okay—it was Boondock Echo. It was a radio project that aimed to make it easy to record and playback conversations from two-way radio communications. The project was entered via Hackaday.io, the judges dug it, and it was one of the top projects of that year’s competition.

The project was the brainchild of Mark Hughes and Kaushlesh Chandel. At the 2023 Hackaday Supercon, Mark and Kaushlesh (KC) came back to tell us all about the project, and how far it had come one year after its success in the 2022 Hackaday Prize.

Supercon 2023: Restoring The Apollo Guidance Computer

Humans first visited the Moon in 1969.  The last time we went was 1972, over 50 years ago. Back then, astronauts in the Apollo program made their journeys in spacecraft that relied on remarkably basic electronics that are totally unsophisticated compared to what you might find in an expensive blender or fridge these days. Core among them was the Apollo Guidance Computer, charged with keeping the craft on target as it travelled to its destination and back again.

Marc Verdiell, also known as CuriousMarc, is a bit of a dab hand at restoring old vintage electronics. Thus, when it came time to restore one of these rare and storied guidance computers, he was ready and willing to take on the task. Even better, he came to the 2023 Hackaday Supercon to tell us how it all went down!

A CO2 Traffic Light On An SAO

[David Bryant] clearly has an awareness of the impact of an excess concentration of CO2 in the local environment and has designed an SAO board to add a CO2 traffic light indicator to one of the spare slots on the official Hackaday Supercon 2024 badge.

The part used is the Sensirion SCD40 ‘true’ CO2 sensor, sitting atop an Adafruit rider board. [David] got a leg up on development by creating a simple SAO breakout board, which could have either the male and female connectors fitted, as required. Next, he successfully guessed that the badge would be based around the RP2040 running MicroPython and hooked up an Adafruit Feather RP2040 board to get started on some software to drive the thing. This made hooking up to the official badge an easy job. Since the SAO has only two GPIOs, [David] needed to decode these to drive the three LEDs. There are a few ways to avoid this, but he wanted to relive his earlier EE college years and do it the direct way using a pair of 74HC00 quad NAND gate chips.

We’ve seen a few CO2 monitors over the years. This sleek little unit is based around the Seeeduino XIAO module and uses an LED ring as an indicator. Proper CO2 monitors can be a little pricey, and there are fakes out there. Finally, CO2 is not the only household pollutant; check out this project.

Supercon 2024: Badge Add-On Winners

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.

Supercon 2024: Streaming Live

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.
