The United States Department of Defense just launched the world's first government-funded bug bounty program named HackThePentagon. Following the example of Facebook, Google, and other big US compani...

If you ever read any old magazines, you might be surprised at how inexpensive things used to be. A U.S. postage stamp was six cents, a gallon of gas was $0.34, and the same amount of milk was $1.07…

There’s a reason that the bog-standard serial port will never die. It’s just so robust and simple. When you need a console that will absolutely work with minimal software and hardware, …

[Jeremy Cook] has been playing around with strandbeests for a while, but never had one that walked until he put a motor on it and made it R/C controlled.

These remote controlled strandbeests can't...

Not since the cold fusion confusion of 1989 has the pop science media industry had a story like the EmDrive. The EmDrive is a propellantless thruster – a device that turns RF energy into forc…

If you’ve got an old calculator, Commodore 64, or any other device that used a tape recorder to store and retrieve data, you’ve probably also got a bunch of cassettes lying around, righ…

Researchers at Nanyang Technical University and the University of California at Berkley wanted to answer the question: how do you make a small drone that can fly all day? The problem is that a drone ...

Designing parts to fit perfectly together is hard. Whether it's the coarseness of our fabrication tools or the procedures of the vendor who makes our parts, parts are rarely the exact dimension that w...

Not too long ago we announced the Hackaday Meetups. We were hoping at least a few dozen people would be excited to host a meetup in their town. What we got was hundreds of people and we couldn't be ha...

Arduino is the perfect introduction to microcontrollers and electronics. The recent trend of powerful, cheap, ARM-based single board Linux computers is the perfect introduction to computer science, pr...

We posted about a 3D printer fire a while back. An attendee of the Midwest RepRap Fest had left his printer alone only to find its immolated remains on his return. In the spirit of open source, nat…

In the open hardware world, we like to share 3D design files so that our friends and (global) neighbors can use and improve them. But we've all printed things from time to time that we'd like to keep ...

[Anthony Garofalo] has made a fancier plasma speaker. Not content with a simple spark, he uses a plasma vortex. To make the vortex, the spark gap is swapped out for an electrode placed in the centr…

[Stephen B.] kickstarted a MicroPython board. When he got it, he was pleasantly surprised to find that it worked great. His jaded soul balmed with a good experience, he found himself armed with a t…

If you do a lot of one-off parts on your CNC machine you’ll know setup is the worst part of the process. Usually you’re using scrap material, you have to figure out how you’re goi…

From watching a heart valve in operation to meeting your baby before she’s born, ultrasound is one of the most valuable and least invasive imaging tools of modern medicine. You pay for the va…

Bela is a cape for the BeagleBone Black that’s aimed at artists and musicians. Actually, the cape is much less than half of the story — the rest is in some clever software and a real-ti…

Everyone needs a cute robotic buddy, right? [Matthew Hallberg] created WireBeings, an open source 3D printed robotic platform. Looking like a cross between Wall-E and Danbo, WireBeings is designed a...

Ask a hundred people why they like to escape to the forest and you’ll probably get a hundred reasons, but chances are good that more than a few will say they seek the peace and quiet of the w…

The first of the BBC Micro Bits are slowly making their ways into hacker circulation, as is to be expected for any inexpensive educational gadget (see: Raspberry Pi). [Martin] was able to get his hand...
