Tiny Arcade, Based On Arduino

November 21, 2015 by 16 Comments

Who can resist video games when they’re packed up in tiny, tiny little arcade machines? [Ken]’s hoping that you cannot, because he’s making a cute, miniature Arduino-based arcade game platform on Kickstarter. (Obligatory Kickstarter promo video below the break.)

The arcades are based on [Ken]’s TinyCircuits Arduino platform — a surprisingly broad range of Arduino modules that click together using small snap connectors in place of pin headers. The system is cool enough in its own right, and it appears to be entirely open source. Housing these bits in a cute arcade box and providing working game code to go along with it invites hacking.

There’s something about tiny video cabinets. We’ve seen people cram a Game Boy Advance into a tiny arcade cabinet and re-house commercial video game keyfobs into arcade boxes. Of course, there’s the Rasbperry Pi. From [Sprite_TM]’s cute little MAME cabinet to this exquisite build with commercially 3D-printed parts, it’s a tremendously appealing project.

But now, if you’re too lazy to build your own from scratch, and you’ve got $60 burning a hole in your pocket, you can get your own tiny arcade — and tiny Arduino kit — for mere money. A lot of people have already gone that route as they passed the $25k funding goal early yesterday. Congrats [Ken]!

Arcades: Don’t Call It A Comeback

October 6, 2015 by 14 Comments

nothing2Video arcades may be a thing of the past, but they’re still alive, well and were ready to play at this year’s World Maker Faire. The offerings weren’t old favorites, all were brand new games many being shown for the first time like the long-awaited VEC9. The Hall of Science building was filled with cabinets and no quarters were necessary, all were free-play.

Death By Audio Arcade was there in force with games like Particle Mace and Powerboat Italia ’88. Our personal favorite was Nothing Good Can Come of This. [Michael P. Consoli] devised a simple game: Two players in an empty room. A bullet drops from a hole in the ceiling, followed by a gun shortly thereafter. What happens next is up to the players. The simple graphics and gameplay give this title its charm. [Michael] was showing off a new stand-up cabinet for the game this year. He built the entire thing himself, working until the wee hours before load-in at Maker Faire.

[Batsly Adams], [Todd Bailey], and [Mike Dooley] teamed up to create what may be the first new vector arcade in decades. VEC9 has been teased for over 2 years. They’ve finally wrapped this game up and showed it off at the faire. VEC9 started with an old
Asteroids vector monitor found by [Batsly].

A Tiny Arcade Machine With Tinier Buttons

November 4, 2014 by 15 Comments

Building a MAME machine around a Raspberry Pi has been the standard build for years now, and tiny versions of full-sized arcade machines have gone from curiosity to commonplace. [diygizmo] just built one of these tiny arcades, but the fit and finish of this one puts it above all others. There’s a real, miniature joystick in there, along with 3D printed adapters for tact switches to make this one look like a lilliputian version of a full size standup MAME cabinet.

The entire enclosure is 3D printed, and most of the electronics are exactly what you would expect: A Raspberry Pi, 2.5″ LCD, and a battery-powered speaker takes up most of the BOM. Where this build gets interesting is the buttons and joystick: after what we’re sure was a crazy amount of googling, [diygizmo] found something that looks like a normal arcade joystick, only smaller. Unable to find a suitable replacement for arcade buttons, [diygizmo] just printed their own, tucked a tact switch behind the plastic, and wired everything up.

Add in some decals, paint, and the same techniques used to create plastic model miniatures, and you have a perfect representation of a miniature arcade machine.

Mini Ms. Pacman

MsThe 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.

Mini Supergun PCB

November 25, 2013 by 18 Comments

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 (link dead, try the Internet Archive version).

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.

Galaga Mini-Cabinet Using A Nintendo DS

We’re not showing you the finished version of this tiny Galaga arcade cabinet because it doesn’t really testify to the awesome that was packet into this hack. In regards to the features the build is just nuts!. The user controls were customized to look like the real thing, and the attention to detail would make craftsmen from the gilded age of dollhouses proud.

Update: [eLRIC] left a link to an even better forum thread build log as a comment. Among other thing it fully details the joystick modifications.

The machine is driven by a Nintendo DS, which donates its upper screen as the cabinet display. In the image to the right you can see that the lower display is still accessible through an opening in the back of the cabinet. The joystick is a small multi-directional switch which was altered by adding the red ball. It was also housed in a custom metal bracket that includes a washer to limit the movement of the stick. Also shown on the right are the lights for the marquee as well as the two coin-slots.

Check out the video after the break to see the game play. Despite its size it still seems really playable, but if you need something larger you could model your own build off of this project.
