Oxford is a city world-famous for its university, and is a must-see stop on the itinerary of many a tourist to the United Kingdom. It features mediaeval architecture, unspoilt meadows, two idylic r…

One of the promises of 3D printing is that you can mass produce objects at home, printing out multiple copies of whatever you want. Unfortunately, the reality is a bit different: once you have prin…

Summer is here, and it’s time for the question on everyone’s mind: how are they going to get the fuselage of a 747 from the California desert to Burning Man? You can’t put it on a…

Earlier this year, [Dan Maloney] went inside mechanical calculators. Being the practical sort, [Dan] jumped right into the Pascaline invented by Blaise Pascal. It couldn’t multiply or divide.…

An ergometer is a fancy fitness word for a rowing machine, a device which can be used to work out the muscles used in rowing. It’s an excellent cardio workout that can also build upper body s…

While many of the Arduino platforms are great tools for gaining easy access to microcontrollers, there are a few downsides. Price and availability may be the highest on the list, and for those reas…

If you’re looking to get started in designing a few PCBs, you could use one of the many software packages that allow you to create a PCB quickly, easily, and with a minimum amount of fuss. Yo…

Like many people, [Mike] has a list of things he wants to do in life. One of them is “fire a gun with a switch,” and with a little help from some hacker friends, he knocked this item of…

Just when it seems like we’ve juiced all the creative potential out of our 3D printers, a bold new feature lands on the table. Enter Velocity Painting, a concept brought to life by [Mark Whea…

If you follow the desktop 3D printer market, it probably won’t surprise you to hear that nearly every 3D printer on display at the inaugural East Coast RepRap Festival (ERRF) was made in Chin…

Assuming you have a child and it’s no longer womb-bound, there’s a fairly high chance they’ve already had some experience with the glowing beauty that is the LCD display; babies o…

Congratulations and thank you go to Theodore Yapo for authoring the first paper to complete the peer review process for the Hackaday Journal. You can read the standalone paper here; it will be incl…

When we need actuators for a project, a servo from the remote-control hobby world is a popular solution. Though as the number of servos go up, keeping their wires neat and managing their control si…

We are smack-dab in the middle of our Energy Harvesting Challenge, and [wasimashu] might have this one in the palm of his hand. Imagine a compact flashlight that doesn’t need batteries or bul…

As we all know, sometimes the projects we plan simply never materialize. You have an idea, maybe even buy some of the parts you need, and then…nothing. Maybe you changed your mind, or maybe t…

While quadcopters seem to attract all the attention of the moment, spare some love for the rotary-wing aircraft that started it all: the helicopter. Quads may abstract away most of the aerodynamic …

If you just came down in the last shower, you’re probably used to living in a world where LEDs are cheap, awesome, and practically everywhere. Spare a thought for those of us who lived before…

We’ve seen the supercomputer cluster work of [Nick Smith] from the UK before, but his latest build is quite lovely. This time around, he put together a 96-core supercomputer using the NanoPi …

There seems to be a universal truth on the Internet: if you open up a service to the world, eventually somebody will come in and try to mess it up. If you have a comment section, trolls will come i…

Readers with long memories will remember the days when mice and other similar pointing devices relied upon a hard rubber ball in contact with your desk or other surface, that transmitted any motion…
