An Arcade Cabinet With Displays To Spare

January 31, 2020 by 15 Comments

We’ve all got a pretty good mental image of what an arcade cabinet looks like, so you probably don’t need to be reminded that traditionally they are single-screen affairs. But that idea dates back to when they were built around big and bulky CRT displays. Now that we have modern LCD, LED, and OLED panels, who says you have to follow the old rules?

That’s precisely the sort of out of the box thinking that lead [Al Linke] to build this unique multi-display arcade cabinet. The game itself is still played on a single screen, but several smaller sub-displays are dotted all around the cabinet to indicate various bits of ancillary information. Are they necessary? Hardly. But we can’t deny it’s a clever idea, and we wouldn’t be surprised if we start seeing something similar in other DIY cabinets.

The build started with a commercially available cabinet from Arcade1Up, which at this point are popular enough that some of the Big Box retailers have them in stock. All of the electronics except for the display were stripped out, and replaced with a Dell OptiPlex 9020 computer and high-quality joysticks and buttons. [Al] then installed his various displays all over the cabinet, including a gorgeous LED marquee that we’ve featured previously.

So what do all these little screens do? [Al] explains them in the video after the break, but the general idea is that they provide contextual information about the game you currently have loaded up. A two-color OLED display shows the name of the game and what it’s rated, while a seven segment LED display shows the year the game was released. The displays are located both by the controls and where you’d expect the coin slot to be, so whether you’re actively playing or across the room, you can see all the information.

We’re always amazed to see how builders find ways to make their own personal arcade cabinets stand out. While it’s an idea that at this point we’ve seen quite a lot of, no two projects have ever been quite the same.

A Custom Raspberry Pi 4 Arcade Cabinet

January 25, 2020 by 29 Comments

Over the years we’ve covered quite a few Raspberry Pi based arcade cabinets, and admittedly many of them have been fairly similar. After all, there’s only so much variation you can make before it stops looking like a traditional arcade machine. But even still, we never tire of seeing a well executed build like the one [Dawid Zittrich] recently shared with us.

These days you can order a kit that has pre-cut panels to build your cabinet with, but looking for a completely custom build, [Dawid] decided to first model his design in SketchUp and then cut out the panels himself with a jigsaw. This obviously is quite a bit more work, and assumes you’ve got sufficient woodworking tools, but we think the final result looks great. Not to mention the fact that it’s going to be a lot stronger than something made out of MDF.

He also created the side artwork himself, taking the logos and names from his favorite arcade and Amiga games and putting them on a retro-looking gradient pattern.  The marquee on the top has an acrylic front and is illuminated from behind with strips of LEDs. It’s mounted on a hinge so that it can be lifted up and a new piece of art slid in without taking apart the whole cabinet. While it might be a little more labor intensive to switch out than some of the electronic marquees we’ve seen, we do like that you still have the ability to change the artwork on a whim.

With the cabinet itself completed, [Dawid] turned his attention to the electronics. Inside you’ve got the aforementioned Raspberry Pi 4 (with a Noctua fan to keep it cool), an external hard drive, a HDMI to VGA converter with scanline generator to drive the 4:3 ratio Eizo Flex Scan S2100 monitor, and a rather beefy amplifier hanging off the Pi’s 3.5 mm analog audio output. All of which is easily accessible via a maintenance hatch built into the cabinet so [Dawid] doesn’t need to tear everything down when he wants to tweak something.

If you’d like to have that arcade cabinet feel but don’t have the space and equipment to put something like this together, you could always stick a Raspberry Pi into an iCade and call it a day.

Arcade Buttons Make A Great Multimedia Keyboard

December 22, 2019 by 4 Comments

[Giovanni Bernardo] has a very important job – managing the audio for several Christmas events. Desiring a simple and effective control interface, he designed a dedicated media keyboard to run the show.

The project began with an Arduino Leonardo, commonly used in projects that aim to create a USB Human Interface Device. [Giovanni] then installed the HID-Project library from [Nicohood]. This was used to enable the device to emulate media buttons typically found on keyboards, something the standard Arduino HID libraries were unable to do. It’s a useful tool, and one that can be implemented on even standard Arduino Unos when used in combination with the HoodLoader2 bootloader.

For ease of use and a little bit of cool factor, arcade buttons were used for the media functions. Simple to wire up, cheap, and with a great tactile feel, they’re a popular choice for fun human interface projects. It’s all wrapped up in a neat plastic box with Dymo labels outlining the functions. It’s a neat and tidy build that should make running the Christmas show a cinch!

Swapping The ROMs In Mini Arcade Cabinets

December 6, 2019 by 10 Comments

You’ve probably seen a few of these miniature arcade games online or in big box retailers: for $20 USD or so you get scaled-down version of a classic arcade cabinet, perfect for a desk toy or to throw up on a shelf as part of your gaming collection. Like any good Hackaday reader, you were probably curious about what makes them tick. Thanks to [wrongbaud], we don’t have to wonder anymore.

Over the course of several blog posts, [wrongbaud] walks readers through the hardware and software used in a few of these miniature games. For example, the Rampage cabinet is using a so-called “NES on a Chip” along with a SPI flash chip to hold the ROM, while Mortal Kombat is using a Genesis emulation solution and parallel flash. It wouldn’t be interesting if they didn’t throw you a few curves now and again, right?

But these are more than simple teardowns. Once [wrongbaud] gives an overview of the hardware, the next step is reading the respective flash storage and trying to make sense of the dumped data. These sort of games generally reuse the hardware among a number of titles, so by isolating where the game ROM is and replacing it, they can be made to play other games without hardware modification. Here, this capability is demonstrated by replacing the ROM data for Rampage with Yoshi’s Cookie. Naturally it’s one of those things that’s easier said than done, but it’s an interesting proof of concept.

The Mortal Kombat cabinet is a newer addition to the collection, so [wrongbaud] hasn’t progressed quite as far with that one. The parallel flash chip has been dumped with the help of an ESP32 and a MCP23017 I/O expander, and some Genesis ROM headers are identifiable in the data, but there’s still some sifting to be done before the firmware structure can be fully understood.

Even if you’re not in the market for a diminutive arcade experience, the information that [wrongbaud] has collected here is really phenomenal. From understanding protocols such as I2C and SPI to navigating firmware dumps with a hex editor, these posts are an invaluable resource for anyone looking to get started with reverse engineering.

Barcaderator Is Coin-Op Arcade Up Top And Kegerator Down Below

November 25, 2019 by 11 Comments

It’s a common sight in our community for a life-expired arcade cabinet to be repurposed as a MAME cabinet with an up-to-date screen and other internals. Many of us have had some fun pursuing high scores in a hackerspace somewhere, and even if they don’t have the screen burn and annoying need for cash of the originals they still deliver plenty of fun.

But if there’s one pleasure an adult can pursue that a kid in a 1980s arcade couldn’t, it’s a cool glass of beer. [Marcus Young] has brought together the two with his Barcaderator, a custom MAME cabinet with a beer tap on the side and a fridge for a keg in its base.

Beer tap built in!
Split cabinet detail

The MAME internals include a Lattepanda Alpha and an LED controller for those illuminated buttons. Where this build shines is in its custom cabinet, which instead of being an all-in-one unit takes the form of a base and top half that are detatchable. It appears to take its inspiration and build techniques from the world of flight cases. You can see the detail where the two halves come together in this image. The result should be of great interest to anyone who has struggled with moving an unwieldy traditional arcade cabinet.

This is we think the first beer/arcade combo to grace these pages. But we’ve had more than one arcade cabinet, and definitely quite a few kegs along the way.

Building A DIY Desktop-Sized Arcade Machine

June 29, 2019 by 10 Comments

Full-sized arcade cabinets are undeniably cool, but take up a lot of space and can be somewhat of a handful. [PleaseNoFisticuffs] desired something a little more fun-sized, and so built a desktop arcade machine that has some serious style.

It’s a build that’s remarkably accessible for even the inexperienced builder. Paper templates are used to cut out the plywood parts for the cabinet, and the electronic components are all off-the-shelf items. Assembly is readily achievable with high-school level woodworking and soldering skills. Like most similar builds, it relies on the Raspberry Pi running RetroPie, meaning you’ll never run out of games to play.

Where this project really shines, however, is the graphics. Cribbed from Mortal Kombat II and looking resplendent in purple, they’re key to making this cabinet a truly stunning piece. The attention to detail is excellent, too, with the marquee and screen getting acrylic overlays for that classic shine, as well as proper T-moulding being used to finish the edges.

We’d love to have something like this on our desk, though we’d likely get far less work done in such an event. For another take on an arcade build, check out this impressive Undertale pinball cabinet.

 

LEDSpicer Is An Open Source Light Controller For Your Arcade Machine

June 13, 2019 by 8 Comments

In this day and age of cheap and easy emulation, it’s more tempting than ever to undertake a home arcade cabinet build. If you want to show off, it’s got to have a light show to really pull the crowds in. To make that easier, [Patricio] put together a software package by the name of LEDSpicer.

The project came about when [Patricio] was working on his Linux-based MAME cabinet, and realised there were limited software options to control his Ultimarc LED board. As the existing solutions lacked features, it was time to get coding.

LEDSpicer runs on Linux only, and requires compilation, but that’s not a huge hurdle for the average MAME fanatic. It comes with a wide variety of animations, as well as tools for creating attract modes and managing LEDs during gameplay. There are even audio-reactive modes available for your gaming pleasure. It’s open source too, so it’s easy to tinker with if there’s something you’d like to add yourself.

It’s a great package that should help many arcade builders out there. LEDs can be used to great effect on a cabinet build; this marquee is a particularly good example. Video after the break.
