For a little while it was possible to spend Bitcoin twice. Think of it like a coin on a string, you put it into the vending machine to get a delicious snack, but if you pull the string quickly enou…

In a surprising move, ARM has made two Cortex-M cores available for FPGA development at no cost. In the over three decades since [Sophie Wilson] created the first ARM processor design for the Acorn…

Level-up your hardware chops at the Hackaday Superconference. We’re delighted to share more of the amazing speakers who are headed to Pasadena in just a few weeks. Scroll down for eight incre…

They adorn the ends of Cat5 network patch cables and the flat satin cables that come with all-in-one printers that we generally either toss in the scrap bin or throw away altogether. The blocky rec…

Building your own robot is something everyone should do, and [Ahmed] has already built a few robots designed to be driven around indoors. An indoor robot is easy, though: you have flat surfaces to …

Conventional 3D printing and other additive manufacturing methods are highly effective at producing parts of irregular geometries that are difficult or impossible to create with other methods. Howe…

When home consoles go mobile, whether in the form of modded original hardware or emulation, they usually take a pretty standard shape. A screen in the middle, with buttons either on the sides or be…

Ever since Google’s Deep Dream results were made public several years ago, there has been major interest in the application of AI and neural network technologies to artistic endeavors. [Helen…

If you are a lover of all-things remote-conteolled, it’s likely that you know a thing or two about controllers. You’ll have one or two of the things, both the familiar two-joystick type…

If you’ve spent an afternoon at the sticks of a remote-controlled aircraft, you’re probably well aware of the great limiter for such exploits: battery life. In the days when most RC air…

Fair warning that [Freerk Wieringa]’s videos documenting his giant non-electric robot build are long. We’ve only watched the first two episodes and the latest installment so far, all of…

A high school friend once related the story about how his father, a chemist for an environmental waste concern, disposed of a problematic quantity of metallic sodium by dumping it into one of the m…

Mars ain’t the kind of place to raise a kid. In fact, it’s cold as hell. There’s no one there to raise them if you did, or is there? Is there life on Mars? That’s the questi…

The drum beat of the Hackaday Superconference grows louder. Are you ready for it? We’re spending the week revealing the talks and on our third day we’re barely half-way through. Check o…

We like the ICE40 FPGA from Lattice for two reasons: there are cheap development boards like the Icestick available for it and there are open source tools. We’ve based several tutorials on th…

Well this is unusual. Behold the Magic Flute of Rat Mind Control, and as a project it is all about altering the response to the instrument, rather than being about hacking the musical instrument it…

If you want to plug a USB cable into your next project, you’ve got a problem. USB is not UART, and UART is what every microcontroller serial port wants. To add USB to your microcontroller pro…

Some electronics gear is built for the roughest conditions. With rugged steel cases, weatherproof gaskets, and cables passing through sealed glands, these machines are built to take the worst that …

For all those who have complained about Rubik’s Cube solving robots in the past by dismissing purpose-built rigs that hold the cube in a non-anthropomorphic manner: checkmate. The video below…

It used to be that Web browsing was simple. You asked a server for some text, which was duly sent, and then formatted by your browser. Now a web page is as likely to be a full-blown application tha…

One of the biggest advantages of using the ESP8266 in your projects is how easy it is to get WiFi up and running. Just plug in the WiFi library, put the SSID and encryption key in your source code,…
