Scratch-Built Bar Top MAME Cabinet

April 7, 2015 by Rich Bremer 6 Comments

Video game enthusiast [Mike] is all about the journey and not necessarily the destination. That is why he likes working on projects and documenting their progress with great detail. His bar top MAME machine is certainly no exception.

One of [Mike’s] goals was to see if he could keep the look and feel of a large arcade cabinet but scale it down so that it was portable. He started with drawing up a model in Sketchup. Once satisfied with the layout and making sure everything would fit, the side panels were cut out of pine boards and will only be clear-coated. The remaining panels are cut from MDF as they will be covered in a matching decorative vinyl wrap.

The control panel may look simple but a lot of thought went into it. Of course, there is a joystick but [Mike] chose to only use 4 game-play buttons. He did this to save space and estimates he’ll still be able to play 90% of the available MAME games. Those 4 buttons are illuminated and the MAME front end, Mala, was configured to light up only the functional buttons for the particular game being played. Front and center on the control board is a rotary encoder for playing games like Arkanoid or games requiring a steering wheel.

In the end this build came out pretty nice looking. His build log is a great reference to hit before starting your next arcade cabinet project.

Although [Mike] calls his MAME cabinet ‘mini’, it’s not the most mini we’ve seen here on Hackaday.

Push-Button Degaussing For An Arcade CRT

September 23, 2014 by Kristina Panos 21 Comments

[Ed] was tasked with adding push-button degaussing to an arcade cabinet’s CRT console. The display can be rotated to portrait mode for games that require it, but each time this is done, the magnetic fields get out of whack.

Fortunately, the schematics arrived with the display. [Ed] found that the degauss coil is connected in series with a PTC fuse in an odd arrangement that he didn’t agree with. He decided to use an SSR to switch the coil, and after making lots of transistor-based designs on paper, grabbed a nearby Arduino.

[Ed] took off the PTC and soldered in two wires to its pads for the SSR. He added a wire to the power supply decoupling cap to power the new deguassing circuit and connected the SSR to the Arduino as an open collector input. There was just enough space available to mount the relay to the frame’s base and the Arduino on the side. [Ed] wrote a short method to trigger the SSR and reconnected the PTC fuse. Now it degausses at power up as well as on demand.

Table-Top MAME Cabinet Dubbed “The Water Cooler”

Table-Top MAME Cabinet Dubbed "The Water Cooler"

[Greg] wanted to build a MAME cabinet. Not one of those monsters that take up a bunch of floor space, mind you: this one would be table-top size. He admits he could have made his game system out of new, currently available, off the shelf parts, but part of the design goal was to reuse old hardware that was kicking around. It was important to [Greg] to keep unnecessary waste out of the landfill.

An old PC motherboard was pulled out of an old desktop. It’s not fast enough for use as an everyday computer but it will be totally sufficient for a MAME machine. The project’s screen is an old 13 inch Gateway CRT computer monitor. Notice that it is turned 90 degrees so that it is taller than it is wide. This screen orientation lends itself better to certain types of games. The monitor’s plastic casing was removed before some measurements were taken. SketchUp was used to plan a basic idea of the cabinet.

The controls consist of a joystick and 4 buttons. During past projects, [Greg] has had experience with the least-expensive arcade controls available on eBay. Well, you get what you pay for. This time around he ponied up the extra cash for some high quality controls and is satisfied with the purchase. These buttons were wired straight into a PS/2 keyboard so the computer does not know the difference between the keyboard keys or recently added controls… another great re-use of old obsolete hardware.

The cabinet is made from MDF, glued and screwed together. The limited wood working tools available wasn’t a show stopper for this dedicated builder. For example, the square hole for the joystick was made by removing most of the material with a spade drill bit before using a chisel to clean up the edges. Doing it this way was a little tedious, but you have to do what you have to do sometimes. Once the entire cabinet was finished, several coats of paint were added in a yellow and blue water-theme. Black rubber molding finishes off the edges of the cabinet nicely.

PirateCade Is An Impressive Feat Of Woodworking And Design

Retro Arcade Machine Keeps the Classics

A six month journey of blood sweat and tears is finally over for [David Carver] and what he is left with is nothing short of beautiful. He calls it the PirateCade. We call it the perfect arcade cabinet.

This project is actually [David’s] very first Raspberry Pi project – at least it was, until his Pi crapped out on him. After running into too many problems with it and SD card corruptions, [David] decided against the RetroPie project platform and decided to upgrade to a full-blown PC, using an AtomicFE front-end and the Ultimark Ipac.

The entire cabinet is hand made out of solid wood; he didn’t have access to any fancy CNC routers or laser cutters. We gotta hand it to him, he’s quite the cabinet maker for an electronics guy. Continue reading “PirateCade Is An Impressive Feat Of Woodworking And Design” →

Broken Laptop Lives Again In Skull ‘n Wrenches Arcade Cabinet

July 2, 2014 by Kristina Panos 8 Comments

We’re pretty fond of home-built arcade cabinets, especially when those cabinets feature a giant HaD logo on the front. We teased you with a picture of two predators playing it at Maker Faire Kansas City, and we thought you might like to see what makes it tick.

[Dustin and Nick] have dubbed this the Dustin and Nick Arcade [DNA]. They built the cabinet from the ground up out of 5/8″ MDF, primed it, and painted it with exterior paint to ward off moisture damage. At the heart of this build is the bottom half of a laptop that suffered from a broken screen. The plexiglass overlay lets players view the guts of the thing, which we think is a nice touch that literally exemplifies Open Design.

So, what happens when you drop your proverbial coin? [Dustin and Nick] used an C# NES/SNES emulator that runs from the command line using a WPF interface. [Nick]’s software selects the appropriate emulator for the approximately 700 available games. You’ll find [Nick]’s code and a ton of build pics at [Dustin]’s site. No wonder they won a Maker of Merit ribbon!

Don’t have the space to build a full-scale cabinet? You could make a mini Ms. Pac-Man cabinet, but then you’d only have Ms. Pac-Man to play with. And we’re pretty sure she’s spoken for.

Mini Ms. Pacman

June 2, 2014 by Brian Benchoff 5 Comments

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.

Pictures over on [Jason]’s G+ page, along with a vertical video that G+ displays properly. Thanks, Google.

Neo Geo Arcade Gets Second Life With A Raspberry Pi

April 14, 2014 by Adam Fabio 9 Comments

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]!
