It’s always nice to see new developments in the world of electronic badges, and while there are events and badge teams pushing the technological envelope there’s still plenty of scope for innovation without too many exotic parts. This year’s DORS/CLUC open source conference in Croatia has just such a badge, with a large alphanumeric LED […]
Just a quickie for anyone who is in the neighborhood, today the annual Open Source Hardware Summit conference starts in Edinburg, Scotland. If you’re able to make it, it’s a microcosm of the open-source hardware world, and full of great talks and great hackers. If you’re not in Scotland, they have a livestream on YouTube […]
When you’re hunting for a signal with your oscilloscope, the stronger it is, the better. If it’s weak, you might struggle to tease it out from other interference, or even from the noise floor itself. You might wish that you were looking for something more obvious rather than the electromagnetic equivalent of a needle in […]
We’re tremendously excited to be able to announce that the Hackaday Supercon is on for 2025, and will be taking place October 31st through November 2nd in Pasadena, California. Supercon is about bringing the Hackaday community together to share our great ideas, big and small. So get to brainstorming, because we’d like to hear what […]
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, […]
We often think of analog computing as a relic of the past, room-sized monstrosities filled with vacuum tubes doing their best to calculate Monte Carlo simulations or orbital velocities. Analog isn’t as dead as it might seem though, and analog mix signal design engineer [Nanik Adnani] gave us a crash course on analog circuits at […]
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 […]
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 […]
When it comes to our machines, we generally have very prescribed and ordered ways of working with them. We know how to tune our CNC mill for the minimum chatter when its chewing through aluminium. We know how to get our FDM printer to lay perfect, neat layers to minimize the defects in our 3D […]
If you had to guess, what do you think it would take to build an ocean-going buoy that could not only survive on its own without human intervention for more than two years, but return useful data the whole time? You’d probably assume such a feat would require beefy hardware, riding inside an expensive and […]
