PC And Console Gaming United Courtesy Of Origin

July 25, 2019 by Maya Posch 13 Comments

When folk at Origin PCs realized that their company was about to celebrate its 10th anniversary of making custom (gaming) PCs, they knew that they had to do something special. Since one thing they did when the company launched in 2009 was to integrate an XBox 360 into a gaming PC, they figured that they might as well refresh and one-up that project. Thus 2019’s Project ‘Big O’ was born.

Naturally still featuring a high-end gaming PC at its core, the show piece of the system is that they also added an XBox One X, Playstation 4 Pro and Nintendo Switch console into the same full-tower GENESIS chassis. For this they had to strip the first two consoles out of their enclosures and insert them into the case each along with their own (appropriately colored) watercooling loop. Unfortunately the optical drives got ditched, presumably because this made things look cleaner.

The Switch was not modded or even cracked open. Instead a Switch dock was installed in the front of the case, allowing one to dock the Switch in the front of the case, and still use it in a mobile fashion after undocking it. Meanwhile an Ethernet and HDMI switch simplify the interfaces to this gaming system a lot, requiring one to only plug in a single HDMI and Ethernet cable to plug in all capable platforms. The result is a pretty sleek-looking system, definitely an eye-catcher.

Since Origin will never, ever, sell the Big O to customers as it’s just a promotional item, it does tickle the imagination. Case-modding and combining multiple computers (often an ATX and mini-ITX) system into a single case is nothing new, but aspects such as having a dockable Switch feature, this clean aesthetic and overall functionality makes one wonder what an enterprising hobbyist could accomplish here.

Deducing Stepper Motor Wiring

July 25, 2019 by Al Williams 12 Comments

There are a lot of fun projects you can do with stepper motors salvaged from old printers or disk drives. However, it isn’t always clear how to connect to some strange motor with no markings or schematics. [Corvetteguy50] has a video showing his trick for working out the connections easily, and you can see it below.

The basic idea is simple. Using a special jig, he connects an LED across two random pins and spins the motor. If the LED lights, you’ve found a coil. You just don’t know which coil, yet. You can also short two wires and note when you feel resistance when you spin the shaft.

Neopixels Recreate Pinball Color Wheel That Never Was

July 25, 2019 by Dan Maloney 6 Comments

With what pinball aficionados pay for the machines they so lovingly restore, it’s hard to imagine that these devices were once built to a price point. They had to make money, and whatever it took to attract attention and separate the customer from their hard-earned coins was usually included in the design. But only up to a point.

Take the 1967 Williams classic, “Magic City.” As pinball collector [Mark Gibson] explains it, the original design called for a rotating color filter behind a fountain motif in the back-glass, to change the color of the waters in an attractive way. Due to its cost, Williams never implemented the color wheel, so rather than settle for a boring fountain, [Mark] built a virtual color wheel with Neopixels. He went through several prototypes before settling on a pattern with even light distribution and building a PCB. The software is more complex than it might seem; it turns out to require a little color theory to get the transitions to look good, and it also provides a chance for a little razzle-dazzle. He implemented a spiral effect in code, and added a few random white sparkles to the fountain. [Mark] has a few videos of the fountain in action, and it ended up looking quite nice.

We’ve featured [Mark]’s pinball builds before, including his atomic pinball clock, We even celebrated his wizardry in song at one point.

College Project Nets 360 Degree POV Display

July 25, 2019 by Lewin Day 14 Comments

Senior college projects are the culmination of years of theoretical learning finally put into practice. For many students they are their first experience of doing some proper, real world engineering. [Melangeaddict] chose to take on a persistence of vision display for his final project, and learned plenty along the way.

The display consists of a row of 48 RGB LEDs mounted on an arm capable of rotating a full 360 degrees, with a simple paper diffuser. This arm is spun up by a belt drive from an electric motor at significant rotational speed, so getting close to this machine is quite inadvisable. Thanks to quality bearings and a careful build, rotating resistance is minimal. An infrared LED is mounted on the frame, and the light picked up by a photodiode on the rotating arm, allowing the images to remain fixed in space without drifting over time. Images can be loaded to the display wirelessly over a Bluetooth interface, which was quite advanced for a DIY project in 2011.

We’re a fan of the 360 degree approach to POV displays, and with the right rotational speed and fast data rates, it would be possible to get some seriously high resolution out of the device. Just be careful not to stick your hands in the mechanism.

There’s a deep well to explore when it comes to POV displays, from three-dimensional builds to vibrating flexible setups. Video after the break.

Tiny Game System Is An Experiment In Minimalism

July 25, 2019 by Tom Nardi 22 Comments

Many people assumed the smartphone revolution would kill the dedicated handheld game system, and really, it’s not hard to see why. What’s the point of buying the latest Nintendo or Sony handheld when the phone you’re already carrying around with you is capable of high-definition 3D graphics and online connectivity? Software developers got the hint quickly, and as predicted, mobile gaming has absolutely exploded over the last few years.

But at the same time, we’ve noticed something of a return to the simplistic handheld systems of yore. Perhaps it’s little more than nostalgia, but small bare-bones systems like the one [Mislav Breka] has entered into the 2019 Hackaday Prize show that not everyone is satisfied with the direction modern gaming has gone in. His system is specifically designed as an experiment to build the most minimal gaming system possible.

In terms of the overall design, this ATMega328 powered system is similar to a scaled-down Arduboy. But while the visual similarities are obvious, the BOM that [Mislav] has provided seems to indicate a considerably more spartan device. Currently there doesn’t seem to be any provision for audio, nor is there a battery and the associated circuitry to charge it. As promised, there’s little here other than the bare essentials.

Unfortunately, the project is off to something of a rocky start. As [Mislav] explains in his writeup on Hackaday.io, there’s a mistake somewhere in either the board design or the component selection that’s keeping the device from accepting a firmware. He won’t have the equipment to debug the device until he returns to school, and is actively looking for volunteers who might be interested in helping him get the kinks worked out on the design.

CampZone 2019 Badge Is Begging To Become A Huge Billboard

What has 256 full-colour LEDs, everyone’s favorite Lithium battery form factor, wireless connectivity, and hangs around your neck? It’s the CampZone 2019 badge that turns all attendees into a really fun billboard — but can the attendees hack themselves into one massive display?

One of Europe’s larger events for the gaming community, CampZone is hosted in Netherlands and runs from July 26th to August 5th. It’s a typical large summer camp, and caters for those who intersect gaming and hacking with HackZone, a decent sized hacker camp within a camp. I’ve been fortunate enough to get my hands on a CampZone 2019 badge, dubbed the I-Pane, let’s take a look at what they managed to pack into this electronic conference badge.

One Week Left For Supercon Talk And Workshop Submissions

July 25, 2019 by Elliot Williams No comments

The Hackaday Superconference is the highest density of the coolest hackers anywhere. Other events may be bigger, but we’ll be so bold to say that none are better. If you love Hackaday, and we know you do, you should really come join us in November in Pasadena, CA.

Far and away the best way to participate in a conference is to participate in the conference. This is your chance to give a presentation or a workshop and share your hard-earned knowledge, your crazy hacks, or entertaining tales of hardware heroism with a crowd that gets it. And you get free admission if we pick your talk for the big show.

One of my favorite tales from Supercon was meeting Jennifer Wang at her (and my!) first Supercon. She was a longtime Hackaday reader, and was honestly a little bit awed to meeting all of the great people there in person. By the next Supercon, she was giving a presentation about her IMU-based machine learning Harry Potter wand and inspiring the rest of us with her love of the cool things you can do with sensors and code. It’s one of the most honest and informative talks on machine learning I’ve seen!
