Hackaday Europe 2026: Fluid Kernels And Optimizing C++ For MCUs

Oftentimes, when we’re using a microcontroller, we’re whipping up some very specific code focused on executing a particular task. The device is set up to execute code that does exactly what we want with minimal overhead. However, sometimes, there are scenarios where it pays to go with a somewhat heavier setup, wherein the microcontroller runs an operating system for the benefits that offers.

Federico Terraneo came to Hackaday Europe to discuss this very topic. He talks about kernel architecture, real-time operating systems, and how to best use C++ in the world of microcontrollers.

Hackaday Europe 2026: Playstation 4 To Psychometer

There are many ways to detect stress in an individual. You can use self-reporting checklists, you could try and measure various vital signs like respiratory rate and pulse and infer things, or you could observe the levels of hormones like cortisol in the blood.

Or… you could pull some parts out of a Playstation 4, and get hacking. Edwin Hwu did precisely that, creating a device that can image the skin down to the nanometer and potentially even determine fine details about an individual’s health status. He came to Hackaday Europe 2026 to tell us all about it.

Hackaday Europe 2026: High Performance SDR On The Cheap

Radios were once big complicated appliances, full of warm valves and paper-wrapped capacitors, all humming and glowing to capture signals from the aether and spit them out of a speaker. Every component was chosen to build the radio to suit a particular purpose.

These days, we have altogether fancier technology that lets us build radios that can be reconfigured on the fly; software-defined radios, if you will. [Anders Nielsen] has been exploring how to build a high-performance SDR recently, and came to Hackaday Europe 2026 to tell us all about it.

Supercon 2024: An Immersive Motion Rehabilitation Device

When you’ve had some kind of injury, rehabilitation can be challenging. You often need to be careful about how you’re using the affected parts of your body, as well as pursue careful exercises for repair and restoration of function. It can be tedious and tiring work, for patients and treating practitioners alike.

Juan Diego Zambrano, Abdelrahman Farag, and Ivan Hernandez have been working on new technology to aid those going through this challenging process. Their talk at the 2024 Hackaday Supercon covers an innovative motion monitoring device intended to aid rehabilitation goals in a medical context.

Supercon 2024: Turning Talk Into Action

Most of us have some dream project or three that we’d love to make a reality. We bring it up all the time with friends, muse on it at work, and research it during our downtime. But that’s just talk—and it doesn’t actually get the project done!

At the 2024 Hackaday Supercon, Sarah Vollmer made it clear—her presentation is about turning talk into action. It’s about how to overcome all the hurdles that get in the way of achieving your grand project, so you can actually make it a reality. It might sound like a self-help book—and it kind of is—but it’s rooted in the experience of a bonafide maker who’s been there and done that a few times over.

Supercon 2024: Photonics/Optical Stack For Smart-Glasses

Smart glasses are a complicated technology to work with. The smart part is usually straightforward enough—microprocessors and software are perfectly well understood and easy to integrate into even very compact packages. It’s the glasses part that often proves challenging—figuring out the right optics to create a workable visual interface that sits mere millimeters from the eye.

Dev Kennedy is no stranger to this world. He came to the 2024 Hackaday Supercon to give a talk and educate us all on photonics, optical stacks, and the technology at play in the world of smart glasses.

Supercon Call For Proposals Extended: July 16th

Ever since the first Supercon, people have submitted talk proposals at the very last minute, and some even in the minutes after the last minute. We know how it is – we are fully licensed procrastineers ourselves. So with an eye toward tradition, we’re extending the Call for Speakers and the Call for Workshops one more week, until July 16th.

The Hackaday Superconference is really and truly our favorite event of the year. It’s small, but not too small. The ideas everyone brings with them, however, are big. It’s like the absolute best of Hackaday live and in person. If you’re looking for a place to give a technical talk, or just to regale us all with the trials and triumphs of hacking, you won’t find a more receptive audience anywhere. Plus, presenters get in free.

In other news, [Voja] has an alpha version of the badge finished, so all that’s left is 90% of the work disguised as 10%. Some people have asked for clues, and what we’ll say at this point is that “Simple Add Ons have underutilized I2C pins”.

Expect tickets to go on sale in the next weeks – early bird tickets sell out fast. Keep your eyes on Hackaday for the announcement post when it goes live. Or, you can skip straight to the front of the line by giving a talk. But you can’t give a talk if you don’t submit your proposal first. Get on it now, because we’re not going to extend the CFP twice!
