The bragging rights of owning a vintage arcade machine are awesome, but the practicality of it – restoring what is likely a very abused machine, and the sheer physical space one requires – doesn’t appeal to a lot of people. [Jason] has a much better solution to anyone who wants a vintage arcade machine, but doesn’t want the buyer’s remorse that comes with the phrase, “now where do we put it?” It’s a miniaturized Ms. Pacman, mostly scale in every detail.
The cabinet is constructed out of 1/8″ plywood, decorated with printed out graphics properly scaled down from the full-size machine. Inside is a BeagleBone Black with a 4.3″ touchscreen, USB speakers, and a battery-backed power supply.
The control system is rather interesting. Although [Jason] is using an analog joystick, the resistive touch screen monopolizes the ADC on the BeagleBone. The solution to this problem would be to write a driver, or if you’re [Jason], crack the joystick open and scratch away the resistive contact until you have a digital joystick. A nice solution, considering Ms. Pacman doesn’t use an analog joystick anyway.

An old Neo Geo Arcade, a Raspberry Pi, and some time were all [Matthew] needed to build this Pi Powered Arcade Emulator Cabinet.
Neo Geo was originally marketed by SNK as a very expensive home video console system. Much like the Nintendo Play Choice 10, SNK also marketed an arcade system, the MVS. The Neo Geo MVS allowed arcade operators to run up to six titles in a single cabinet. The MVS also allowed players to save games on memory cards.
[Matthew’s] cabinet had seen better days. Most of the electronics were gone, the CRT monitor was dead, and the power supply was blown. Aside from a bit of wear, the cabinet frame was solid and the controls were in good shape. He decided it would be a good candidate for an emulator conversion.
We’ve seen some pretty awesome arcade conversions in the past, such as this Halloween rendition of Splatterhouse. For his conversion, [Matthew] stuck to the electronics, leaving most of the old arcade patina intact. The CRT did fire up after some components were replaced. [Matthew] ran into some refresh rate issues with the Raspberry Pi, so he opted to swap it out with a modern LCD monitor. Controls were wired up with the help of an I-PAC board.
[Matthew] had to write a driver to handle the I-PAC, but he says it was a good learning experience. Aside from the LCD screen, the result looks like it could be found in the back of an old bowling alley, or a smokey bar next to Golden Tee. Nice work, [Matthew]!
[Dave] tipped us about the latest project he just finished: a posable, desktop NES clone arcade machine. This idea came to be when its creator gathered a few bits and pieces he had lying around: an NES Retro Entertainment System (Retrobit RES, found for less than $25) and an arcade stick with its buttons. [Dave] then bought a 7″ car DVD screen (less than $40) and started a first standard arcade-looking design with OpenSCAD. As the first draft was relatively boring, he let it mature for a bit until he got another idea, shown in the picture above.
The final result is made of 3D printed PLA and varnished luaun plywood which gives the console a VCS style retro look. Many hours were required to 3D print the different parts using a Makerbot Replicator 2. [Dave] disassembled his Retrobit RES to layout its parts inside the case and also replaced the original voltage regulator with a 7805 on a big heatsink. This may be one of the best ‘nintendo’ hacks we have received over the years, but there have been others that also take cartridges.
There are plenty of Raspberry Pi arcade builds out there, but rarely do we come across something as sleek as [Jochen Zurborg’s] RasPi Arcade Stick. The build combines everything you’d expect from other RasPi arcade projects, but manages to pack everything into the form factor of a portable stick modeled on the Neo Geo 4’s button layout. It may not be as small as the tiny MAME cabinet from last year, but it definitely delivers a more authentic arcade experience.
[Jochen] had previously developed an add-on PCB for the Pi called the PiJamma, which simplifies connections from the RasPi’s GPIOs by providing a JAMMA interface for the controller(s). The Pi and the PiJamma sit inside a custom-made acrylic enclosure and hook up to the buttons and joystick above. Rather than try to fit the Pi directly against a side panel for access to the various outputs, [Jochen] rerouted the USB, HDMI, and headphone jacks and arranged them into a tidy row on the back side of the box. The top piece of the enclosure consists of a sheet of aluminum wrapped in custom artwork, with an additional sheet of acrylic on top for protection. [Jochen] also modified each of the arcade buttons to include LEDs that illuminate the buttons’ acrylic holder, and the case itself appears to have been cut into slats on each side to provide better ventilation.

[Kris]’ house/office has a huge store window, and instead of covering it up with newspapers, decided to do something cool. He’s had projections and other art pieces on display for his neighbors, but his new storefront arcade game very likely beats all of those.
Every video game needs a display, and this one is no slouch. The display is a 16*90 matrix of WS2812 LEDs with inset into a laser cut grid and put behind a layer of plexiglass. With this grid, the display has a great raster effect that’s great for the pixeley aesthetic [Kris] was going for. In front of the window is an MDF and steel arcade box powered by an Arduino Due.
The game is driven by the Adafruit neopixel library, with a few modifications to support alpha blending. There’s no external memory for this game – everything is running on a second Arduino Due inside the window.
It’s a great looking game, and if you’re ever in [Kris]’ area – behind the zoo in Antwerp – you’re free to walk up and give this game a spin.
Video demo below.

A few decades ago, Japanese manufacturers of arcade games realized they should make a connector for all their boards that provides the power, controller, video, and audio I/O. This became the JAMMA standard and it make arcade owner’s lives awesome. Because you can buy arcade boards off the Internet, arcade enthusiasts figured out they could build their own console with an ATX power supply, AV connectors, and a few controllers. These ‘superguns’ as they’re called are big devices with wires all over the place. [Charlie] wanted to condense the size of his supergun and ended up creating a single PCB solution.
The JAMMA compatable boards require a few power connections; +5 V, +12 V, and -5 V. Of all the boards [Charlie] has collected so far, he realized only one used the negative supply. This, along with a big 12V laptop power supply, means the only power connection for this mini supergun is a single barrel connector.
For the controls and A/V, DSub and SCART connectors are commonplace. Laying these parts out in Eagle resulted in a single-sided board that is easily fabbed by etching with a toner transfer at home.
There are a few problems with the build, as [Charlie] admits. Some of the pins on the JAMMA connector aren’t on the board. These are only ground pins on the pinout, and so far everything works okay. It’s still a great project, though, that turns old arcade boards into a playable device with a minimal amount of hardware.
It’s already pretty cool that [Clay] co-owns an Arcade, but he’s really impressed us with his custom-made Splatterhouse cabinet built to get his patrons in the Halloween spirit! A Namco brawler title from 1988, Splatterhouse came in an unadorned and otherwise forgettable cabinet. [Clay] salvaged an old Williams Defender, coating the sides with a cocktail of drywall compound, sand, and paint to achieve a stone texture. He then carved up some pink insulation foam into a tattered “wooden” frame and used it as a monitor bezel. For accents, he fashioned strips of latex to resemble torn flesh and placed them among the boards. The control panel is yet another work of art: [Clay] 3D printed a life-size human femur for the game’s joystick, and converted the buttons to look like eyeballs.
[Clay] decided to go beyond the stunning cosmetics, though, and tapped into the game’s CPU with a custom daughterboard that detects different in-game events and state changes such as player health. An ATMega165 uses four PWM outputs connected to a number of LEDs inside the cabinet and around the monitor bezel to react to the different events. If a player takes damage, red lights flash around the monitor. Inserting a coin or dying in the game causes a different set of LEDs behind the marquee to go nuts.
Check out his detailed project page for more information and see a video overview below. If building a full-scale arcade machine is out of your budget, you can always make a tiny one.
