The next great advancement in homebrew electronics is an easy way to turn copper clad board into functional circuit boards. This has been done since the 60s with etch resist pens, sheets of etch re…

[Dave] just couldn’t take the ambient noise from his Lulzbot Mini anymore, so he built a fancy fan controller for it. He measured some points on the printer’s Rambo controller board to …

If you recall, there was a recent standoff between Apple and the U. S. Government regarding unlocking an iPhone. Senators Richard Burr and Dianne Feinstein have a “discussion draft” of …

A while back I wrote a piece titled, "It’s Time the Software People and Mechanical People Sat Down and Had a Talk". It was mostly a reaction to what I believe to be a growing problem in the hacker...

One of my favorite conversation from Saturday's Hackaday | Belgrade conference was about border crossing. This guy was saying the border station coming into Serbia needed a separate lane with the Skul...

It’s funny how creation and understanding interact. Sometimes the urge to create something comes from a new-found deep understanding of a concept, and sometimes the act of creation leads to t…

CMOS imaging chips have been steadily improving, their cost and performance being driven by the highly competitive smartphone industry. As CMOS sensors get better and cheaper, they get more interes…

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…
