More than one hundred years ago, Henri Becquerel discovered that uranium emitted penetrating rays similar to those used by Wilhelm Röntgen to take the first X-ray image (of his wife’s hand), …

Mathematics, as it is taught in schools, sometimes falls short in its mission to educate the pupils. This is the view of [Joan Horvath] and [Rich Cameron], particularly with respect to the teaching o...

SCSI devices were found in hundreds of different models of computers from the 80s, from SUN boxes to cute little Macs. These hard drives and CDROMs are slowly dying, and with that goes an entire ge…

The Teensy is a powerful ARM-based development board with loads of features that can do fun stuff with USB as well. Like many dev boards, it uses a less powerful processor as an interface. Teensy d…

Is it too much to ask for a home to have a little 'smart' built-in? If you've ever woken up (or come home) to your dwelling being flooded, you'll know how terrible it feels, how long it can take to re...

[Avian] has been using STM32 ARM processors to sample RF for a variety of applications. At first, he was receiving relatively wide TV signals. Recently, though, he’s started dealing with very…

Oscilloscopes have come a long way. Today's scope is more likely to look like a tablet than an old tube-based instrument. Still, there's something about looking into a glowing green tube, especially i...

Watching Tony Stark wave his hands to manipulate projected constructs is an ever-approaching reality — at least in terms of gesture-tracking. Lift — a prototype built by a team from UC …

Betteridge’s Law of Headlines states, “Any headline that ends in a question mark can be answered by the word no.” This law remains unassailable. However, recent claims have called…

What's the worst thing that could happen if you strapped a chainsaw motor to a tricycle? Turns out the worst that happened to [ThisDustin] and his friends is that it turned out hilariously awesome.

A few weeks ago we published an article on the newly released Keysight 1000X, an oscilloscope that marks Keysight’s late but welcome entry into the hacker-centric entry-level market. Understa…

For those that suffer them, seizures are a dangerous thing. Outside the neurological effects, there is always the possibility of injury from the surrounding environment as well – consider the…

[bd594] likes to make strange objects. This time it's a robotic glockenspiel and hacked HDD's. [bd594] is no stranger to Hackaday either, as we have featured many of his past projects before inclu...

Inspiration can strike from the strangest places. Unearthing a forgotten Melexis MLX90614 thermopile from his  'inbox,' [Saulius Lukse] used it to build a panoramic thermal camera.

[Lukse] made us...

Craft stores are often the source of odd inspiration. In the stained glass section, we've seen the copper foil, and even used it to prototype some RF circuits on the tops of shoeboxes. However, we cou...

Have you ever wondered how you could look at a chip and map out its schematic? [Robert Baruch] wants to show you how he does it and he does in a new video (see below).  The video assumes you know h…

For those who love to hike, no excuse is needed to hit the woods. Other folks, though, need a little coaxing to get into the great outdoors, which is where geocaching comes in: hide something in the w...

QNX has a long checkered history as an embedded operating system. QNX was always famous for being a real time operating system with a microkernel architecture. That is, kernel functions run as a se…

Starting up a new hackerspace from the ground up is a daunting task. Before you even think about the fun stuff like tools and a space, you've got a ton of social engineering to do. Finding like-minde...

Surface mount diodes are simple enough -- all you need to do is make sure you have the anode and cathode in the right order when you place them on the pad when you solder them. These SMD diodes come i...

Learn the ins and outs of multi-core microcontrollers as Chip Gracey leads this week's Hack Chat on Friday 5/5 at noon PDT. Chip founded Parallax and has now been working for more than a decade on...
