When featuring cool hacks repurposing one thing for something else, we prefer to focus on what we could get our hands on and replicate for ourselves. Not this one, though, as nobody else has the mi…

Those who were around for the pre-floppy days of computer mass storage were likely to have made the mistake of slipping a cassette tape containing data into a stereo tape deck. Instead of hearing t…

We live in a world where anyone can build a CT machine. Yes, anyone. It’s made of laser-cut plywood and it looks like a Stargate. Anyone can build an MRI machine. Of course, these machines ar…

Ah, crap. We lost a good one, people. [Samm Sheperd] passed away last month. We’ve seen his stuff before, from a plane with a squirrel cage fan, to completely owning a bunch of engineering st…

It is good advice to change batteries in your fire alarms at least once a year. Even our low-power LCD calculators need new batteries from time to time. But at the University of Oxford, they have a…

It’s been a long, long time since we heard from Opportunity, the remarkable Mars rover that has shattered all expectations on endurance and productivity but has been silent since a planet-wid…

Running a server completely off solar power seems like it would be a relatively easy thing to do: throw up a couple of panels, tack on a charge controller and a beefy battery, and away you go. But …

After exploring a few random online shops one day, [David] (thanks for sending this in, by the way) ran across a very interesting chip. It’s a dual-core, RISC-V chip running at 400MHz. There&…

Soon, perhaps even by the time you read this, the rules for flying remote-controlled aircraft in the United States will be very different. The Federal Aviation Authority (FAA) is pushing hard to re…

As far as game consoles go, the Nintendo Wii was relatively small. Probably owing at least somewhat to the fact that it wasn’t a whole lot more than a slightly improved GameCube in a new case…

Come one, come all, this is the megapost about the Hackaday Superconference. Join us in Pasadena on November 2-4 for the hardware conference you cannot miss. Get your ticket quickly as they will se…

Many of us have experienced the pain that is a Raspberry Pi with a corrupted SD card. I suspect the erase-on-write nature of flash memory is responsible for much of the problem. Regardless of the c…

The last challenge of The Hackaday Prize has just ended. Over the past few months, we’ve gotten a sneak peek at over a thousand amazing projects, from Open Hardware to Human Computer Interfac…

Hackers love 3D printers. In fact, they might love them a little too much. We hope know we aren’t be the only ones who couldn’t turn down a good deal on an overseas printer (or two). Bu…

[The LED Artist] often found a need for a relatively high voltage (100 to 200 Volt) but low current DC power supply, and it turns out that a small HV generator that uses a single AA cell only took …

We were contacted by [morbo] to let us know about a project on the AdaCore blog that concerns programming a PicoRV32 RISC-V softcore with Ada. The softcore itself runs on a Lattice ICE40LP8K-based …

There’s something about art. Cavemen drew on walls. People keep programming drawing robots. One we’ve seen recently is [Andy’s] Drawbot that uses WiFi and WebSockets to draw on ju…

Microsoft is bringing ROS to Window 10. ROS stands for Robot Operating System, a software framework and large collection of libraries for developing robots which we recently wrote an introductory a…

We love the fall here at Hackaday. The nights are cooler, the leaves are changing, and our tip line starts lighting up with some of the craziest things we’ve ever seen. Something about terrif…

Google is pulling the plug on their social network, Google+. Users still have the better part of a year to say their goodbyes, but if the fledgling social network was a ghost town before, news of i…
