The Little Lightgun That Could: Sinden Makes Good

June 22, 2022 by Tom Nardi 13 Comments

Back in 2018, we covered the work being done by [Andrew Sinden] to create a lightgun that could work on modern televisions. The project was looking for funding via Kickstarter, but due at least in part to skepticism about the technology involved, the campaign fell well short of its goal. It seemed, at the time, like the story would end there.

But we were recently pointed to a fascinating interview with [Andrew] that ran in The Guardian a couple months back that not only tells the rest of the story, but concludes with a happy ending — after years of hard work, the Sinden Lightgun is now available for purchase. It’s not exactly the turn-key product that some would like, as there’s a fair number of hoops one must jump through just to bag some eponymous waterfowl in Duck Hunt, but nothing that would scare off the average Hackaday reader.

Limited technical details about the 2018 prototype may have kept backers away.

The final version of the hardware ditches the realistic firearm aesthetic inherited from the Wii gun accessory it was designed to fit into, and now features a brightly-colored pistol enclosure that wouldn’t look out of place tethered to a Virtua Cop machine. It’s also gained an optional recoil solenoid for force feedback, though it tacks on another $60 to the already hefty $100 price tag for the base model.

We’re glad to see that [Andrew] recognized the importance of getting Linux support for the software side of things, as it enabled the development of a pre-configured Retropie image for the Raspberry Pi 4. Though you aren’t forced to emulate on the Pi, for those who would like to blast the occasional zombie on their desktop, Windows and x86 Linux are also supported.

Often times, when we cover a project here on Hackaday it’s a one-shot deal: somebody had a particular need or desire, built a gadget to fulfill it, and moved on. There’s nothing wrong with that, but there’s a certain feeling of pride when we see a project from this community develop into something more. While not every hacked together piece of hardware we feature has the potential to be the next Arduboy or Sinden Lightgun, we like to think that we’ve already covered the next big project-turned-product success story and just don’t know it yet.

Bartop Arcade Machine That Isn’t Afraid Of Change

September 3, 2021 by Matthew Carlson 24 Comments

Arcade machines have a distinct look and feel with large imposing cabinets and smaller bartop machines that try to keep the look and feel of a traditional upright arcade cabinet while taking up less space. An entirely new aesthetic has been given for this engineering marvel of a bartop arcade that [DIY Engineering] has made. Gone is the expansive angular box, and in its place are sleek and slender curves. The key piece that makes this build work is the curved monitor.

He started with a detailed design in Fusion360 that really focused on the tools and techniques that [DIY Engineering] knew would work. The backbone of the device was formed from wooden dowels around which 3d printed parts slid on. To the sides of the dowels, two pieces of acrylic are screwed on to act as an LED diffusor. To that acrylic, two pieces of CNC’d red oak are attached with two arcade buttons for pinball-style actuation. Over the top, cast acrylic was heated and then bent into the desired shape with the help of a two-part mold press. The screen slotted right in perfectly. Part of the display at the top was reserved for a marquee, and the look is extraordinary with the dark acrylic. Ten arcade buttons and an eight-way joystick offer an array of options for input.

Internally, a temperature-controlled fan and a Raspberry Pi are running the show. Controls are wired as GPIO and read by the Pi. So naturally, the games on the SD card tend to look best on a long vertical screen: vertical shooters and the like.

Arguably, the best thing about this project isn’t just the execution (which is fantastic) but the look behind the curtain at the process. So many potential problems were solved in the modeling stage, and fabrication went fairly smoothly as a result (or so we think youtube hides a multitude of sins). The results speak for themselves, and we think this is an enviable arcading machine. [DIY Engineering] has mentioned providing files in the future for you to build your own. If perhaps it seems a little intimidating, why not give a smaller 3D printable bartop a try?

3D Printed Pi Arcade Is An Emulation Horn Of Plenty

January 20, 2021 by Tom Nardi 19 Comments

Let’s be honest, building a home arcade cabinet isn’t exactly the challenge it once was. There’s plenty of kits out there that do all the hard work for you, and they even sell some pretty passable turn-key units at Walmart now. If you want to put a traditional arcade cabinet in your home, it’s not hard to get one.

Which is why this wild build by [Rafael Rubio] is so interesting. The entirely 3D printed enclosure looks like some kind of art piece from the 1970s, and is a perfect example of the kind of unconventional designs made possible by low-cost additive manufacturing. Building something like this out of wood or metal would be nightmare, especially for the novice; but with even a relatively meager desktop 3D printer you’re only a few clicks away from running off your own copy.

Removable side panels allow access to the electronics.

Inside the nautilus-like enclosure is a Raspberry Pi running Retropie, a 10″ LCD panel from Pimoroni, and a GeeekPi interface board that connects up to the 8-way joystick and arcade buttons. [Rafael] has included a Bill of Materials and an assembly overview that you can follow along with, though the cavernous internal dimensions of the enclosure certainly give you ample of room for improvisation if you’d rather blaze your own path.

Like the retro-futuristic computer terminals created by [Oriol Ferrer Mesià], this arcade machine completely reinvents a traditional design that most people take for granted. Is this layout actually better than the standard arcade cabinet? It’s not really our place to say. But it’s certainly a new and unconventional approach to “solved” problem, and that’s what we’re all about.

Toddler Arcade Cabinet Is A Stand-Up Job

October 6, 2020 by Kristina Panos 6 Comments

A few years ago, [Mark] built an arcade cabinet into a low table. But once his new gaming buddy [Grayson] came along and started crawling, it wasn’t practical to have a low, pointy table around. Trouble is, [Mark] had already given [Grayson] his first taste with a Thomas the Tank Engine game. Since the kid was hooked, [Mark] rebuilt the table arcade into a toddler-sized arcade cabinet that they can both use.

The brain — a Raspberry Pi running RetroPie — should be familiar to most of our readers. [Mark] found the perfect crappy old monitor when they were upgrading at his office, and found some nice speakers to give it good bass. We love the details like the chrome edging, and especially the kick bar/footrest along the bottom. It can be difficult to decide how to decorate a multi-arcade cabinet, so [Mark] went the sticker bomb route with 700 of them randomly distributed and safe from toddler wear and tear under five coats of clear wood varnish.

We think this looks great, especially since [Mark] doesn’t have a workshop and cut all that MDF by hand on a jigsaw in the kitchen. Check out the happy train engineer after the break.

Maybe once [Grayson] is old enough to break tablets, [Mark] can build a gaming tab-inet out of it. Just sayin’.

You’ve Never Seen This RetroPie Emulator Console: Watermelon

August 26, 2020 by Lewin Day 5 Comments

The Raspberry Pi is a hugely popular platform for emulating older consoles, with the RetroPie framework making it easy to get started in no time at all. Often, these single board computers get built into fun arcade boxes or replica console shells to add to the charm. That’s all been done, so instead, [Cedishappy] decided to go in his own direction – resulting in the wonderful Watermelon Gameboy.

What sounds like a trivial exercise of building a RetroPie rig in a unique enclosure actually comes with some engineering challenges. The basics are all pretty standard – GPIO pins interfacing buttons, a speaker and the screen, emulating a Gameboy Advance. But the mechanical implementation is more complex. The watermelon is first cut open, having its red flesh removed, leaving just the rind. Paper and cardboard templates are then used to make holes for the buttons and screen. Unfortunately, hot glue doesn’t work on watermelon, so instead, toothpicks were used to hold the screen and speaker in place. To protect the electronics from the moist melony environment inside, clear food wrap was applied to the Raspberry Pi and other components where needed.

[Cedishappy] goes above and beyond with the project video charmingly showing the reactions of bystanders to the contextually confusing game system. The combination of electronics with fruit and vegetables is an area we don’t see explored often enough; our own [Mike Szczys] built a magnificent LED Jack-o-Lantern that really looks the business.

Miniature Star Wars Arcade Lets You Blow Up The Death Star On The Go

August 12, 2020 by Tom Nardi 10 Comments

If you have fond childhood memories of afternoons spent at the local arcade, then you’ve had the occasional daydream about tracking down one of those old cabinets and putting it in the living room. But the size, cost, and rarity of these machines makes actually owning one impractical for most people.

While this fully functional 1/4th scale replica of the classic Star Wars arcade game created by [Jamie McShan] might not be a perfect replacement for the original, there’s no denying it would be easier to fit through your front door. Nearly every aspect of the iconic 1983 machine has been carefully recreated, right down to a working coin slot that accepts miniature quarters. Frankly, the build would have been impressive enough had he only put in half the detail work, but we certainly aren’t complaining that he went the extra mile.

[Jamie] leaned heavily on resin 3D printed parts for this build, and for good reason. It’s hard to imagine how he could have produced some of the tiny working parts for his cabinet using traditional manufacturing techniques. The game’s signature control yoke and the coin acceptor mechanism are really incredible feats of miniaturization, and a testament to what’s possible at the DIY level with relatively affordable tools.

The cabinet itself is cut from MDF, using plans appropriately scaled down from the real thing. Inside you’ll find a Raspberry Pi 3 Model A+ running RetroPie attached directly to the back of a 4.3 inch LCD with integrated amplified speakers. [Jamie] is using an Arduino to handle interfacing with the optical coin detector and controls, which communicates with the Pi over USB HID. He’s even added in a pair of 3,000 mAh LiPo battery packs and a dedicated charge controller so you can blow up the Death Star on the go.

Still don’t think you can fit one in your apartment? Not to worry, back in 2012 we actually saw somebody recreate this same cabinet in just 1/6th scale.

3D Print Your Way To A Bartop Arcade Cabinet

April 22, 2020 by Tom Nardi 3 Comments

Custom arcade machines have always been a fairly common project in the hacker and maker circles, but they’ve really taken off with the advent of the Raspberry Pi and turn-key controller kits. With all the internals neatly sorted, the only thing you need to figure out is the cabinet itself. Unfortunately, that’s often the trickiest part. Without proper woodworking tools, or ideally a CNC router, it can be tough going to build a decent looking cabinet out of the traditional MDF panels.

But if you’re willing to leave wood behind, [Gerrit Gazic] might have a solution for you. This bartop arcade, which he calls the simplyRetro D8, uses a fully 3D printed cabinet. He’s gone through the trouble of designing it so there are no visible screw holes, so it looks like the whole thing was hewn from a chunk of pure synthwave ore. He notes that this can make the assembly somewhat tricky in a few spots, but we think it’s a worthy compromise.

Given the squat profile of the simplyRetro, the internals are packed in a bit tighter than we’re accustomed to seeing in a arcade build. But there’s still more than enough room for the Raspberry Pi, eight inch touch screen HDMI panel, and all the controls. To keep things as neat as possible, [Gerrit] even added integrated zip tie mount points; a worthwhile CAD tip that’s certainly not limited to arcade cabinets.

[Gerrit] has included not only the STL files for this design, but also the Fusion 360 Archive should you want to make any modifications. There’s also a complete Bill of Materials, as well as detailed instructions on how to pull it all together. If you’ve ever wanted your own arcade machine but felt a bit overwhelmed about figuring out all the nuances on your own, the simplyRetro could be the project you’ve been waiting for.

Of course if you do have access to a CNC or laser cutter, then there are some designs you could produce quite a bit faster.
