A lot of embedded systems are running Linux on platforms like Raspberry Pi. Since Linux is fully functional from a command line and fully network-capable, it is possible to run servers that you&#82…

Hackaday.io just welcomed the 200,000th registered user! We are the world's largest repository of open hardware projects and Hackaday.io is proving its worth as the world's most vibrant technology c...

Wherever you may live in the world, who do you wish to smile upon you and deliver good fortune? You may be surprised to discover that for a significant number of Brits this role is taken by someone…

There's a wide world to explore when it comes to papercraft, but we reserve special praise for fully functional builds. [Aliaksei Zholner's] working papercraft organ is a stunning example of what ca...

You say you need some graphene so you can invent the Next Big Thing, but you can’t be bothered with processes that yield a few measly milligrams of the precious stuff. Luckily for you there&#…

Did you forget about Valentine's Day? Do you need a quick project to get ready for Valentine's Day? [Becky Stern] has you covered. She's whipped up a neat Internet-enabled Valentine project which sho...

The 80's were a golden age of Sci-Fi cartoons. We had Transformers, Voltron, and of course, Thundercats. The story of feline humanoids on third earth has stuck with a few hackers, including [Juan Garc...

Knives are tools that rely heavily on material quality to do their job right. A knife made of cheap steel won't hold an edge well, and blunt knives are more likely to cause injury, or at the least, be...

We’ve seen our fair share of Altoids mint tin projects and it seems the tin… can always house another interesting project. This time [MWAGNER] managed to make his long time idea of havi…

Yes, the pun was ripped off the article that got our attention . It was just too good not to share. A team of researchers in Japan created an artificial honeybee, a small drone that is meant to cros...

This Friday, we're talking RF. Join us for a discussion on designing RF products with Hackaday's very own Jenny List. It's all happening in the Hack Chat on hackaday.io.

When Jenny isn't busy writi...

In the years since the launch of the original Raspberry Pi we have seen the little British ARM-based board become one of the more popular single board computers in the hobbyist, maker, and hacker c…

[Max K] has been testing the battery life of his self-designed watch under real-world conditions. Six months later, the nominally 3 V, 160 mAh CR2025 cell is reading 2.85 V, so the end is near, but…

Whenever I end up with a new vehicle I ultimately end up sticking in a new GPS/Receiver combination for better sound quality and a better GPS. I am quite at home tearing into a dashboard as I was l…

Researchers from VUSec found a way to break ASLR via an MMU sidechannel attack that even works in JavaScript. Does this matter? Yes, it matters. A lot. The discovery of this security flaw along with...

Way back in the before years when there were still interesting concepts for reality TV, Nate Seidle blew up a power supply in his dorm room. Instead of finding replacement parts, Nate decided to star...

We’ve seen a lot of interest in LSM (LASER Scanning Microscopes) lately. [Stoppi71] uses an Arduino, a CD drive, and–of all things–two speakers in his build. The speakers are used…

We don’t think [VK4FFAB] did himself a favor by calling his seven-part LTSpice tutorial LTSpice for Radio Amateurs. Sure, the posts do focus on radio frequency analysis, but these days lots o…

There used to be a time, before running shoes had blinking LEDs and required placing on an inductive charger overnight, when we weren’t worried about whether or not we could dump the firmware…

Here's a slick-looking VGA demo written in assembly by [Yianni Kostaris]; it's VGA output from an otherwise stock ATmega2560 at 16MHz with no external chips involved. If you're getting some Super Ma...
