Super Mario 64 As Experienced By Mario

July 16, 2020 by Bryan Cockfield 4 Comments

Microsoft’s Kinect, a motion-sensing peripherial originally for the Xbox 360, is almost exactly a decade old now. And in that decade it has expanded from its limited existence tied to a console to a widely-used tool for effective and detailed motion sensing, without breaking the bank. While it’s seen use well outside of video games, it’s still being used to reimagine some classic games. In this project, Reddit user [SuperLouis64] has used it to control Mario with his own body.

While the build still involves some use of a hand controller, most of Mario’s movements are controlled by making analogous movements on a small trampoline, including the famed triple jump. The kinect is able to sense all of these movements and translate them into the game using software that [SuperLouis64] built as well. The trickiest movement seems to be Mario’s spin movement, which appears to have taken some practice to get right.

We appreciate the build quality on this one, and [SuperLouis64]’s excitement in playing the game with his creation. It truly looks like a blast to play, and he even mentions in the Reddit thread that he’s gotten a lot of productive excercise with his various VR and augumented reality games in the past few months. Of course if this is too much physical activity, you could always switch to using your car as the unique game controller instead.

Jerry Lawson And The Fairchild Channel F; Father Of The Video Game Cartridge

July 14, 2020 by Jenny List 14 Comments

The video game console is now a home entertainment hub that pulls in all forms of entertainment via an internet connection, but probably for most readers it was first experienced as an offline device that hooked up to the TV and for which new game software had to be bought as cartridges or for later models, discs. Stepping back through the history of gaming is an unbroken line to the 1970s, but which manufacturer had the first machine whose games could be purchased separately from the console? The answer is not that which first comes to mind, and the story behind its creation doesn’t contain the names you are familiar with today.

The Fairchild Channel F never managed to beat its rival, the Atari 2600, in the hearts of American youngsters so its creator Jerry Lawson isn’t a well-known figure mentioned in the same breath as Atari’s Nolan Bushnell or Apple’s two Steves, but without this now-forgotten console the history of gaming would have been considerably different.

(Re)Making A ColecoVision

July 12, 2020 by Al Williams 13 Comments

[Leaded Solder] found some ColecoVision game cartridges at a flea market, and like most of us would, thought, “I’ll build a ColecoVision console from scratch to play them!” Well, maybe most of us would think of that, but not actually do it. He did and you can read about the results in great detail since he wrote up two posts, one covering the design and one covering the construction.

The ColecoVision was a game console that famously could be expanded into a nice — for its day — personal computer. It even had a daisy wheel printer in that configuration. However, in either configuration, the game console was the brains of the operation. According to [Leaded Solder] the price of a unit in working order is high even though over 2 million were made because of several design problems that make them less likely to survive the decades. Rather than repair and modify an original unit, it was cheaper and much more educational to build new.

Robotic Cornhole Board Does The Electric Slide

July 9, 2020 by Kristina Panos 9 Comments

There’s a reason why bowling lanes have bumpers and golf games have mulligans. Whether you’re learning a new game or sport, or have known for years how to play but still stink at it, everyone can use some help chasing that win. You’ve heard of the can’t-miss dart board and no-brick basketball goal. Well, here comes the robot-assisted game for the rest of us: cornhole.

The game itself deceptively simple-looking — just underhand throw a square wrist rest into a hole near the top of a slightly angled box. You even get a point for landing anywhere on the box! Three points if you make it in the cornhole. In practice, the game not that easy, though, especially if you’ve been drinking (and drinking is encouraged). But hey, it’s safer than horseshoes or lawn darts.

[Michael Rechtin] loves the game but isn’t all that great at it, so he built a robotic version that tracks the incoming bag and moves the hole to help catch it. A web cam mounted just behind the hole takes a ton of pictures and analyzes the frames for changes.

The web cam sends the bag positions it sees along with its predictions to an Arduino, which decides how it will move a pair of motors in response. Down in the cornhole there’s a pair of drawer sliders that act as the lid’s x/y gantry.

We love how low-tech this is compared to some of the other ways it could be done, even though it occasionally messes up. That’s okay — it makes the game more interesting that way. We think you should get 2 points if it lands halfway in the hole. Aim past the break to check out the build video.

Seems like there’s a robotic-assisted piece of sporting equipment for everything these days. If cornhole ain’t your thing, how’d you like to take a couple strokes off your golf game?

New (mis)Use For Lithophanes: Miniature Diorama Backgrounds

July 6, 2020 by Donald Papp 3 Comments

What’s better than a well-lit photo of a 3D-printed miniature? A photo of the miniature in a mini diorama, of course. [OrionDeHunter] shows off a clever technique that has something in common with old-timey photo stages and painted backgrounds, and (mis)uses 3D-printed lithophanes to pull it off. What [OrionDeHunter] does is use a curved and painted lithophane as a stand-in for a background, and the results look great!

Lithophanes are intended to be illuminated from behind to show an image, with thin areas showing as lighter and thicker areas darker, but when it comes to high contrast patterned images like brick walls, the same things that make a good lithophane just happen to also make a pretty good 3D model in the normal sense. No 3D scanning or photogrammetry required.

Here is the basic process: instead of creating a 3D model of a brick wall from scratch, [OrionDeHunter] simply converted an image of a brick wall (or stairs) into a curved lithophane with an online tool. The STL model of the lithophane is then 3D printed, painted, and used as a swappable background. When macro shots of the miniatures are taken, the curved background looks just right and allows for some controlled lighting. It’s a neat trick, and well applied in this project. Some sample images demonstrating how it works are just under the break.

A painted lithophane makes a convincing brick wall

Other images like these stairs can work, too.

Lithophanes were originally made using marble or thin porcelain, but a modern spin has been put on the technique with 3D printing. Enterprising hackers have even discovered ways to add color, too.

Finding A Secret Message From A Gaming Legend

July 4, 2020 by Tom Nardi 6 Comments

Satoru Iwata is perhaps best remembered for leading Nintendo through the development of the DS and Wii, two wildly successful systems which undeniably helped bring gaming to a wider and more mainstream audience. But decades before becoming the company’s President in 2002, he got his start in the industry as a developer working on many early console and computer games. [Robin Harbron] recently decided to dig into one of the Iwata’s earliest projects, Star Battle for the VIC-20.

Finding the message was easy, if you knew were to look.

It’s been known for some time that Iwata, then just 22 years old, had hidden his name and a message in the game’s source code. But [Robin] wondered if there was more to the story. Looking at the text in memory, he noticed the lines were actually null-terminated. Realizing the message was likely intended to get printed on the screen at one point during the game’s development, he started hunting for a way to trigger the nearly 40 year old Easter Egg.

As it turns out, it’s hidden behind a single flag in the code. Just change it from 0 to 1, and the game will display Iwata’s long-hidden credit screen. That proved the message was originally intended to be visible to players, but it still didn’t explain how they were supposed to trigger it during normal game play.

That’s where things really get interesting. As [Robin] gives us a guided tour through Star Battle’s inner workings, he explains that Iwata originally intended the player to hit a special combination of keys to tick over the Easter Egg’s enable flag. All of the code is still there in the commercial release of the game, but it’s been disabled. As Iwata’s life was tragically cut short in 2015 due to complications from cancer, we’ll perhaps never know the reason he commented out the code in question before the game was released. But at least we can now finally see this hidden message from one of gaming’s true luminaries.

Last time we heard from [Robin], he’d uncovered a secret C64 program hidden on a vinyl record. With his track record so far, we can’t wait to see what he digs into next. Continue reading “Finding A Secret Message From A Gaming Legend” →

Mini “Gaming PC” Nails The Look, Streams The Games

June 29, 2020 by Tom Nardi 19 Comments

To have a proper gaming “rig”, you need more than a powerful GPU and heaps of RAM. You’ve also got to install a clear side-panel so lesser mortals can ogle your wiring, and plenty of multicolored LEDs to make sure it’s never actually dark when you’re up playing at 2 AM. Or at least, that’s what the Internet has led us to believe.

The latest project from [Michael Pick] certainly isn’t doing anything to dispel that stereotype. In fact, it’s absolutely reveling in it. The goal was to recreate the look of a high-end custom gaming PC on a much smaller scale, with a Raspberry Pi standing in for the “motherboard”. Assuming you’re OK with streaming them from a more powerful machine on the network, this diminutive system is even capable of playing modern titles.

But really, the case is the star of the show here. Starting with a 3D printed frame, [Michael] really went all in on the details. We especially liked the little touches such as the fiber optics used to bring the Pi’s status and power LEDs out to the top of the case, and the tiny and totally unnecessary power button. There’s even a fake graphics card inside, with its own functional fan.

Even if you’re not interested in constructing custom enclosures for your Raspberry Pi, there are plenty of tips and tricks in the video after the break that are more than worthy of filing away for future use. For example, [Michael] shows how he fixed the fairly significant warping on his 3D printed case with a liberal application of Bondo and a straight-edge to compare it to.

This isn’t the first time we’ve seen a Raspberry Pi masquerade as a high-end computer, but it’s surely the most effort we’ve ever seen put into the gag.
