Put a message in a bottle and toss it in the ocean, and if you’re very lucky, years later you might get a response. Drop a floating Arduino-fied buoy into the ocean and if you’ve engine…

The Pine A64 was a 64-bit Quad-Core Single Board Computer that shipped to its backers to almost universally poor reviews. Now they’re back, this time with a laptop—a 11.6-inch model for $89, or a 1…

Machine learning and automated technologies are poised to disrupt employment in many industries -- looking at you autonomous vehicles -- and medicine is not immune to this encroachment. The Qualcomm T...

The first challenge of the 2017 Hackaday Prize closes on this coming Monday morning. You have about 72 hours hours to submit your entry.

The challenge, called Design Your Concept, is really about...

Few people would deny that farming is hard work. It always has been, and it probably always will be no matter how fancy the equipment gets. In 1932, farming was especially grueling. There was widespre...

Mechanical keyboards are the in thing right now and building your own is at least two extra levels of nerd cred. This project, entered in the Hackaday Prize, is a DIY keyboard unlike you've ever seen...

If you need a supply of low pressure air – let’s say enough pressure to ensure a constant supply but not enough to describe as “Compressed air” with a straight face – …

The HD44780 is one of the first chips we learned about as a kid, and chances are good you’ve used one in your project at some point, and almost certain that you’ve interacted with one i…

If you are a follower of the sci-fi horror film genre then it is likely that you will be familiar with the Alien series of movies. Images of Sigourney Weaver bearing a significant amount of firepower...

Flow requires a certain amount of focus, and when that concentration is broken by pesky colleagues, work can suffer, on top of time wasted attempting to re-engage with the task at hand. The Technical ...

[Otermrelik] wanted to experiment with the Teensy audio library and adapter. That, combined with his 3D printer, led to a very cool looking build of the teensypolysynth. The device looks like a lit…

The Internet of Things, as originally envisioned in papers dating to the early to mid-90s, is a magical concept. Wearable devices would report your location, health stats, and physiological informa…

WiFi and Bluetooth have their use cases, but both have certain demands on things like battery life and authentication that make them unsuitable for a lot of low-power use cases. They’re also …

Calculator hacks have been around for a while now and we have seen the most action around the Texas Instruments TI-83 and TI-84. When [johnkimdinh] found a way to add an ESP8266 to a scientific cal…

Some people find it hard to look at a huge, flat expanse of floor or ground and not see a canvas. From the outfield grass of a baseball park to some poor farmer’s wheat field, trampling, trim…

We’re not sure if this is art, anti-snooping guerilla warfare, or just a cheeky hack, but we do know that we like it! [Jasper van Loenen]’s Linger keeps the SSIDs that your cell phone (…

We love custom clocks here at Hackaday, and are always thrilled to see each inventive means of time-keeping. In a seldom-seen take on the familiar device, the [Bastel Brothers]’s LED Strip Cl…

It seems like everyone is building belt grinders these days. You might think [Jeremy Schmidt] is just hoping on the bandwagon, but you’d be wrong. He took a full two years to design the perfe…

If you have ever worked with simple logic gates, there is a good chance that at some point you will have built a ring oscillator from a chain of inverters. With the addition of a resistor and a cap…
