Google’s New OS Will Run on Your Raspberry Pi

Posted on by

According to reports from Android Police and ZDNet, you may soon have a new operating system from Google to run on your Raspberry Pi. Details are still extremely sparse, the only description on the GitHub page is “Pink + Purple == Fuchsia (a new Operating System)”. But, here’s what we do know:

The new OS, called Fuchsia, will be based on Magenta, which is in turn built on LittleKernel. That means that, surprisingly, Google will not be using a Linux kernel for the new OS but something more like an embedded RTOS. Although Google is targeting embedded systems, the possibility …read more

Nuka-Cola PC Case Really Glows

Posted on by

It’s hard to imagine a video game series with more potential for cool prop projects than Fallout. The Fallout series has a beautiful and unique art style that is chock full of potential for real-world builds. Pip-Boys, Fat Mans, and power armor projects abound. But, most of these projects are purely aesthetic: something to stick on a shelf and show off to your fellow geeks.

[themitch22] wanted something he could actually use, and what does a geek use more than their computer? Thus, he set out to create a Fallout-themed PC case, and a Nuka-Cola vending machine was the perfect …read more

Hedberg is a Bionic Hand Made From a Single Keurig

Posted on by

Developing into a modern hacker and tinkerer requires a lot of things: electronics study, programming knowledge, and patience (among many other things). But, the most important quality a hacker can have is curiosity. The desire to see how things work is what drives most budding hackers towards the dismantling of family appliances and electronic gadgets.

Many end up scavenging parts from the things around the house for their first projects. But, with money and more ambitious builds comes the need to purchase parts off the shelf. There is, however, something to be said for the ingenuity that comes with building …read more

Building a Satellite-Tracking System With Cold War Tech

Posted on by

The things Hackaday readers come up with and post over on Hackaday.io never cease to amaze us. If you’ve never checked it out, be careful — you can easily spend hours (or weeks) of your life just skimming through the projects that have been logged there. Many of the builds use modern development tools like Arduino and Raspberry Pi, but every so often we come across a project that takes a more difficult road.

That’s the case with [Keplermatik’s] Cold War-era satellite-tracking project, also aptly named Keplermatik. This a build that’s still in progress, which just means you’ve got the …read more

Building a Full-Spectrum Digital Camera on the Cheap

Posted on by

The sensor on your digital camera picks up a lot more than just the light that’s visible to the human eye. Camera manufacturers go out of their way to reduce this to just the visible spectrum in order to produce photos that look right to us. But, what if you want your camera to take photos of the full light spectrum? This is particularly useful for astrophotography, where infrared light dramatically adds to the effect.

Generally, accomplishing this is just a matter of removing the internal IR-blocking filter from your camera. However, most of us are a little squeamish about …read more

Creo Arm Might be the SCARA You’re Looking For

Posted on by

A SCARA (Selective Compliance Assembly Robot Arm) is a type of articulated robot arm first developed in the early ’80s for use in industrial assembly and production applications. All robotics designs have their strengths and their weaknesses, and the SCARA layout was designed to be rigid in the Z axis, while allowing for flexibility in the X and Y axes. This design lends itself well to tasks where quick and flexible horizontal movement is needed, but vertical strength and rigidity is also necessary.

This is in contrast to other designs, such as fully articulated arms (which need to rotate to …read more

An Apple II Joystick Fix For Enjoyable Gameplay

Posted on by

We all remember the video games of our youth fondly, and many of us want to relive those memories and play those games again. When we get this urge, we usually turn first to emulators and ROMs. But, old console and computer games relied heavily on the system’s hardware to control the actual gameplay. Most retro consoles, like the SNES for example, rely on the hardware clock speed to control gameplay speed. This is why you’ll often experience games played on emulators as if someone is holding down the fast forward button.

The solution, of course, is to play the …read more

You May Have a Nixie Tube Clock, but Can Yours Levitate?

Posted on by

nixie tubes, electromagnets, levitation, and microcontrollers, this project has “Hackaday” written all over it!

Time Flies: Levitating Nixie Clock comes from [Tony Adams], and uses a lot of technology we’ve seen before, but in a new and interesting way. A nixie tube clock is nothing new, but using electromagnets to levitate it above a base certainly paired with inductive coupling to transmit power using no wires make this floating nixie build a real treat.

In order to achieve this feat, [Tony] used coils to wireless transmit power from the base to the floating platform that the tubes are mounted to. …read more

Taking the Converted PC PSU Bench Supply a Step Further

Posted on by

A quality bench power supply is essential for electronics work. Nobody wants to go through the trouble of digging through their electronics bin just to find a wall wart with the right output. And, even if you were so inclined, it would be folly to assume that its output would actually be clean.

You could, of course, purchase a purpose-built bench power supply. But, this is Hackaday, and I’m sure many of you would rather build one yourself from an inexpensive PC power supply. Normally, you’d do this by separating out the different voltage lines into useful groups, such as …read more

Vending Coins for Your Vending Machine

Posted on by

Anyone who has worked in an office with a vending machine knows this problem well: someone wants a snack or a drink from the vending machine, but doesn’t have any small change. So, they proceed to walk around the office trying to find someone to make some change for them. It’s a hassle, and a surprisingly common one. Sure, a lot of vending machines now accept credit cards, but they’re still in the minority.

This was the problem facing Beligum-based automation company November Five. As automation and IoT specialists, their first thought was to hack the vending machine itself. But, …read more
