There is a rule of thumb to follow when looking at product announcements at the fringes of the motor industry that probably has something in common with crowdfunding campaigns. If the photographs o…

There's no shortage of Arduino-based clocks around. [Mr_fid's] clock, though, gets a second look because it is very unique looking. Then it gets a third look because it would be very difficult to read...

FPGAs (like Xilinx’s Spartan series) are great building blocks. They often remind us of the 100-in-1 electronic kits we used to get as kids. Lots of components you can mix and match to make n…

[GregO29] had a 10" GoTo telescope but at 70lbs, it wasn't really portable. And so he did what any self-respecting CNC enthusiast would do, he put his CNC skills to work to make an 8" Newtonian reflec...

[Aguilera Dario] likes his Casio fx-82ES calculator. However, it was missing a few functions, including complex numbers. A Casio fx-991ES has more functions but, of course, costs more. A quick Goog…

As a Hackaday writer, you can never predict where the comments of your posts will go. Some posts seem to be ignored, while others have a good steady stream of useful feedback. But sometimes the com…

[F4HDK] calls his new computer A2Z because he built everything from scratch (literally, from A to Z). Well, strictly speaking, he did start with an FPGA, but you have to have some foundation. The c…

If you watch enough mainstream TV and movies, you might think that hacking into someone's account requires a huge monitor, special software, and intricate hand gestures. The reality is way more boring...

The 1 kB Challenge deadline has come and gone. The judges have done their work, and we’re ready to announce the winners. Before you jump down to find out who won, I’d like to take a mom…

Secret keys are quite literally the key to security in software development. If a malicious actor gains access to the keys securing your data, you're toast. The problem is, to use keys, you've got t...

When you want to play around with a new technology, do you jump straight to production machinery? Nope. Nothing beats a simplified model as proof of concept. And the only thing better than a good p…

The best thing about owning a 3D printer or CNC router may not just be what you can additively or subtractively create with it. With a little imagination you can turn your machine into a 3D scanner, a...

We are always surprised how much useful hacking gear is in the typical craft store. You just have to think outside the box. Need a hot air gun? Think embossing tool. A soldering iron? Check the sta…

The Raspberry Pi single board computer has been an astounding success since its launch nearly five years ago, to the extent that as of last autumn it had sold ten million units with no sign of sale…

There’s a lot of reasons you might want to emulate the keyboard on your Commodore 64. The ravages of time and dust may have put the original keyboard out of order, or perhaps you need to type…

Right now, I’m at Shmoocon, and it’s living up to all expectations. That’s a tall order — last year, the breakout talk was from [Travis Goodspeed] on his efforts to reverse …

Some time back, we posted about [Gavin]'s laser-cut/3D printed Dymaxion Globe -- if you haven't read about it yet, you should check it out. [noniq] loved the idea, and like a true hacker, built and s...

If you remember old computer magazines (or browse them today), you'll see that back in the late 1970s and early 1980s, you weren't always sure what you were going to do with a computer. Games were a s...

Just before the dawn of the PC era, IBM typewriters reached their technical zenith with the Wheelwriter line. A daisy-wheel printer with interchangeable print heads, memory features, and the beginn…
