A few gadgets around the house make for excellent display and conversation pieces, but when an artifact from the wizarding world finds its way into a muggle household? Well, you frame it. Okay so i…

We’re going to go out on a limb here and declare this minuscule incandescent light flasher the smallest such circuit in the world. After all, when you need a microscope to see it work, you&#8…

The Hackaday Prize is more than just giving tens of thousands of dollars to hardware hackers. It's also about funding the next batch of Open Source hardware products. Alongside The Hackaday Prize -- t...

The ESP32 is the successor to the wildly popular ESP8266. There seems to be no end to what the chips can do. However, despite all the wireless communication capabilities, the module doesn’t h…

[Scott Swaaley] needed a bunch of timing pulleys for the clock he was building. He had already decided on the MXL profile, but he needed so many of these toothed pulleys in so many configurations (hex...

[Frank] was lucky enough to score a bucket wheel excavator LEGO set as a birthday present, and we won't lie - we're jealous. However, out of the box, the kit is somewhat limited; there is only one mot...

For all their capacity, shutting down a Raspberry Pi can be a bothersome routine depending on how you have it set up -- historically and abrupt cut to the power risks corrupting the SD card. [madlab5]...

If you want to convert one voltage to another, what do you do? Well, if you are talking DC voltages today, you’ll probably use a DC to DC converter. Really, these converters generate some sor…

Every time we look at the little short Z axis of our CNC mill, we think about converting a drill press to a mill. In theory, it seems like it ought to be easy, but we never quite get around to it. [Av...

You’ve probably heard of Arthur C. Clarke’s third law, suggesting that any sufficiently advanced technology is indistinguishable from magic. Taking this literally and in the best possib…

London is one of those cities with an identity problem when it comes to airports. There is no one London airport, instead a group of airports serve the city at various distances from it. London Gatwi...

[David Brown]’s entry for The Hackaday Prize is a design for a tool that normally exists only as an expensive piece of industrial equipment; out of the reach of normal experimenters, in other…

Anyone who’s made a PCB has encountered the conundrum of having to pay for space that you don’t use… for instance, designing a round PCB and seeing the corners go to waste. The solution? Smaller bo…

Camping and road trips are a heck of a lot of fun, despite lacking many of the creature comforts that come from a house and its amenities. We’re all for fire-cooked meals, but sometimes, you …

Getting paid to do what you enjoy is a special treat. A machinist and fabricator by trade -- hobbyist hacker by design -- [spdltd] was commissioned to build a mechanical art installation with a steamp...

Space is a mess, and the sad truth is, we made it that way. Most satellites that have been lofted into Earth orbit didn't have a plan for retiring them, and those dead hulks, along with the various bi...

We've loved [Daito Manabe]'s work for a while now. Don't know [Daito]? Read this recent interview with him and catch up. Is he a hacker's artist, or an artist's hacker?

My personal favorite hack of...

Whenever there's a new Windows virus out there wreaking global havoc, the Linux types get smug. "That'll never happen in our open operating system," they say. "There are many eyes looking over the sou...

As useful as computers are, most of them have all the design charm of a rubber doorstop. Oh, for the heady early days of computing, when vacuum tubes ruled, hardware was assembled by hand, and engi…

Every Friday, the Hackaday.io community gathers 'round the fireplace and discusses the challenges facing the world. This is the Hack Chat, and in previous incarnations, we've talked about custom silic...
