We love IoT gadgets, but are occasionally concerned that they might allow access to the wrong kind of hacker. In this case, [Kevin] has created an IoT tree that allows anyone to control the pattern…

We love a good drone build here at Hackaday, but no matter how much care is taken, exposed propellers are always a risk: you don’t have to look far on the web to see videos to prove it. Conve…

A Raspberry Pi Zero (W) and Arduino are very different animals, the prior has processing power and connectivity while the latter has some analog to digital converters (ADCs) and nearly real-time re…

Sure there are the occasional functional Christmas tree ornaments; we had one that plugged into the lights and was supposed to sound like a bird gently trilling its song, but was in fact so eardrum…

You may remember that earlier this year Leap Motion revealed Project North Star, a kind of open-source reference design for an Augmented Reality (AR) headset. While it’s not destined to make …

Machine learning is starting to come online in all kinds of arenas lately, and the trend is likely to continue for the forseeable future. What was once only available for operators of supercomputer…

If you’ve been hanging out here at Hackaday for awhile, you’ve certainly seen projects that were based around the concept of putting a miniature computer inside the carcass of some othe…

When you think of microcontroller development, you probably picture either a breadboard with a chip or a USB-connected circuit board. But Tim Ansell pictured an ARM dev board that is almost complet…

The purpose of a Zen garden, those stylized landscapes created by painstakingly placing rocks and raking gravel into perfect patterns, is the doing of the thing. Making sure every line is perfectly…

Most people can tell you the various uses of the umbrella — it keeps the rain off, pokes sleeping train passengers awake, and can be used as an improvised defensive weapon when tension in the…

Can you turn 47 pounds (21 kg) of PLA filament into a gigantic working 3D-printed RC car? No, no you can’t — at least not if you eschew proper bearings in favor of printed bushings. Tha…

Rocketry is wild, and [Foaly] is sharing build and design details of the Cortex 2 mini rocket which is entirely 3D printed. Don’t let that fool you into thinking it is in any way a gimmick; t…

The House of Mouse has been at the forefront of entertainment technology from its very beginnings in an old orange grove in Anaheim. Disney Imagineers invented the first modern animatronics in the …

The only question we have about [mitxela]’s DIY vector graphics game console is: Why did he wait five years to tell the world about it? Judging by the projects we’ve seen before, from h…

Picture this: it’s late in the evening on a freezing cold, dark, and windy December night in southern England, and an airport worker at Gatwick — London’s second international air…

Mechanical keyboards use switches of a few different types. But even those types include myriad variations. How’s a hacker to know just exactly what equipment is out there? For example, if yo…

If you happened to tune into NASA TV on December 11th, you’d have been treated to a sight perhaps best described as “unprecedented”: Russian cosmonauts roughly cutting away the th…

Sometimes you get an epiphany for a project that will change the world. A simple device, on a custom circuit board with inexpensive parts that will disrupt the status quo and make you a billion dol…

If you’re anything like us, your success with the opposite sex at the bar wasn’t much to brag about. But imagine if you had only had this compact CNC polar plotter and could have whippe…
