Building a car engine can be a labor of love. Making everything perfect in terms of both performance and appearance is part engineering and part artistry. Setting your creation apart from the crowd is...

You have to be careful with CNC; it's a slippery slope. You start off one day just trying out a 3D printer, and it's not six months before you're elbow deep in a discarded Xerox looking for stepper mo...

"So just like every other great story in history, ours is going to start at the lathe." Truer words were never spoken, and thus begins the saga of turning a bar of chrome-moly steel into a shop-built ...

There's no piece of technology that has been more useful, more influential on the next generation of sysadmins and engineers, and more polarizing than the Raspberry Pi. For $35 (or just $5), you get a...

If necessity is the mother of invention, then inconvenience is its frustrating co-conspirator. Faced with a finicky dryer that would shut down mid-cycle with a barely audible beep if its load was unev...

[Ben Katz] is building a running robot from hobby level brushless motors, all on his blog under the tag, “HobbyKing Cheetah.” One of the features of fancy modern industrial motor and co…

BB-8 is the much loved new droid introduced in the 2016 movie Star Wars: The Force Awakens, though in my case from the very first trailer released in 2014 I liked it for the interesting engineering…

Kids love Minecraft, and a clever educator can leverage that love to teach some very practical skills. The summer class offered by the Children's Museum in Bozeman Montana would have blown my mind i...

Last fall, I grabbed a robot arm from Robot Geeks when they were on sale at Thanksgiving. The arm uses servos to rotate the base and move the joints and gripper. These work well enough but I found …

The robots we've sent to explore other worlds in our stead are impressive feats of engineering. But stuck at the bottom of our gravity well as we are, they are fantastically expensive ventures that ar...

[dmitry] writes in to let us know about a new project that combines lasers with fans and turns the resulting modulation of the light beams into an autonomous soundscape. The piece is ca...

Superhydrophobic coating finds a new application in art through [Arthur Carabott] in the form of a bizarre fountain.

A Master's student in the Global Innovation Design course at the London Royal Co...

The Internet of Things has been presented as the future of consumer electronics for the better part of a decade now. Billions have been invested, despite no one actually knowing what the Internet of T...

[acidbourbon] had some cool parts on hand, and a musician friend in need of a radio-controlled, touch-sensitive MIDI (and analog) controller. This being Hackaday, you can guess what happened next.

McDonald’s is serious about their fries. When they were forced by shifting public opinion (drunkenly swaggering around as it always does) to switch from their beef tallow and cottonseed oil m…

[Rafael] made a sweet little retro watch that’s a fantastic introduction to hardware DIY. If you’ve programmed an Arduino before, but you’ve never had a board made, and you are up…

One of the most ingenious developments in test and measuring tools over the last few years is the Mooshimeter. That's a wireless, two-channel multimeter that can measure voltage and current simultaneo...

I start each day checking out the new and updated projects over on Hackaday.io. Each day one can find all manner of projects - from satellites to machine vision to rockets. One type of project which i...

[Daiju Ishikawa] wrote us to announce that the world championship Hebocon is taking place this August in Tokyo, and the registration has just opened. When you get a mail in the tip line that reads "Fr...

Numbers are wonderful things when applied to technical specifications. Take [Bobricius]' handheld Arduino-based game console. With an 8x8 LED matrix for a display it's not going to win any prizes, but...
