The Best Pi Emulation Console You Can Build

By far the most popular use for a Raspberry Pi is an emulation console. For an educational device, that’s fine – someone needs to teach kids how to plug a USB cable into a device and follow RetroPi tutorials on the Internet. These emulation consoles usually have one significant drawback: they’re ugly, with wires spilling everywhere. Instead of downloading a 3D printed Pi enclosure shaped like a Super Nintendo, [depthperfection] designed his own. It looks great, and doesn’t have a donglepocalypse hanging out the back.

The biggest factor in building an enclosure for a Pi Zero is how to add a few USB ports. There’s only one USB port on the Pi Zero, although if you’re exceptionally skilled, you can solder a hub onto the test points on the bottom of the board. This stackable USB hub solves the problem with the help of pogo pins for the power and USB pair. It’s only $17 USD, too.

With the USB and power sorted, [depthperfection] set out to design an enclosure. This was modeled in Fusion360, with proper vent holes, screw bosses, and cutouts for all the ports. It’s designed to be 3D printable, and with a little ABS smoothing, this enclosure looks great.

For software, [depthperfection] turned to Recallbox, a retrogaming platform that also doubles as a media player. It’s simpler than a RetroPi installation, but for playing Super Mario 3, you don’t really need many configuration options. This is a great project that just works and looks good doing it. The world — and the Raspberry Pi community — needs more projects like this, and we’re glad [depthperfection] sent this one in.

Observercade, Portable MAME System Of The Future.

[GarageMonkeySan] wrote in to tell us about his latest project. It’s a MAME arcade emulator, but not just any MAME arcade emulator, it is housed in a briefcase. And if that was not interesting enough, it was built in the style of the TV Show “Fringe”, specifically like the Observer briefcases. He calls it the Observercade.

The hard-shelled Samsonite briefcase was taken apart to assess the best way to move forward. A Sintra frame was added to the top half of the briefcase and would hold a scavenged laptop LCD screen. A monitor faceplate was then made from 1/16″ polystyrene sheet to fill the gap around the screen.

The bottom half of the case holds the remaining electronics, which consists of a Raspberry Pi Model B (running RetroPie), power supply, speakers and LCD driver board. They are all mounted to the bottom of the control surface which also supports the controller joystick and buttons. Notice that the buttons are labeled in Observer symbols. These symbols are as accurate as possible roughly translating to ‘credit’, ‘player’… etc. This is a wonderfully done project that shows [GarageMonkeySan] pays extreme attention to detail.

If the Observercade rings a bell, you may be remembering the project that gave [GarageMonkeySan] his inspirations: the Briefcade.

Remember those ‘cocktail’ arcade cabinets? The Ikea Lack table has existed for years, so why not make one into an arcade table? Raspberry Pi with RetroPie as the brains,  and an ancient 4:3 monitor as the display.

Old Unixes! Running on PDPs, Novas, and IBMs! Thanks to Simh, you can emulate these old machines. [Matt] put up a guide to getting Simh running on a Pi that includes running Unix V5 on an emulated PDP-11.

Ever wanted to run your own telecom? The folks at Toorcamp did just that, 50 lines, 10,000 feet of 1-pair, and 1,500 feet of 2-pair. There’s a facebook album of all the pics.

Remember last week when Sparkfun said they shipped 2000 Microviews without a bootloader? Make interviewed [Marcus Schappi], the guy behind the MicroView. There’s also a tutorial on how to fix the issue.

Barbie needs an exorcism.

Remember the [Lord Vetinari] clock from way back when? It’s a clock that ticks 86400 times a day, but the interval between each second is just slightly random and enough to drive people insane. Here’s a kit on Tindie that makes it pretty easy to build a Ventinari clock, or a variety of other clocks that are sufficiently weird. There’s also a martian clock that’s 39 minutes and 36 seconds longer than normal, perfect for the folks at JPL.

The Raspi GameBoy For The Rest Of Us

We’ve seen quite a few casemods that stuff a Raspberry Pi into a Game Boy with all the required to turn it into a very cool portable Pi and retro gaming device. Most of these builds use a modified 20-year-old Game Boy for the enclosure, and if you have an attachment to your old green screened friend, you might not want to cut it up for a Pi project. [Noe] over at Adafruit has a solution – a 3D printed Game Boy enclosure that turns a Pi and TFT screen into a barely pocketable Raspberry Pi, with all the buttons and batteries required for taking an installation of RetroPi on the road.

The PiGRRL, as this build is called, uses the Adafruit touchscreen TFT kit for the Pi, effectively turning the Pi into a very tiny tablet. This allows for normal desktop interaction with the Pi, and it’s also small enough to fit in the smallest of enclosures.

The 3D printed enclosure is the star of the show here, allowing complete access to most of the Pi’s ports, while allowing enough space in the rest of the enclosure for a largish battery, charging circuit, and buttons taken from an SNES controller.

The end result is a very usable portable Pi that just happens to be in the perfect form factor for loading up a few ROMs and playing some classic video games. Video below.

The Game Boy Pocket Raspi Mod Puts All Others To Shame

There are hundreds – perhaps thousands – of builds out there on the Internet that put a Raspberry Pi in an enclosure with buttons meant solely for running emulators for old games. This one is unlike any other. Yes, it’s still basically a RetroPi emulator, but this Game Boy Pocket casemod goes beyond any remotely comparable build.

The Game Boy Pocket is incredibly small, but after sanding down the bosses on the inside of the case, gluing the battery door shut, and installing a bit of plastic over the cartridge slot, [WarriorRocker] was able to fit a Raspi inside. The buttons use the same PCB as the stock Game Boy, connected to a Teensy 2.0 board that simulates a USB keyboard.

With the two largest components taken care of, [Warrior] turned his attention to the sound, video and power. The display is a 2.5″ composite LCD that actually fits quite nicely behind the screen bezel. Audio is taken care of by a $3 audio amplifier, a new, smaller speaker, and a side-mounted pot stolen from the original Game Boy guts. There’s no chance on running this with the same 2xAAA cells the original Game Boy Pocket had, so [Warrior] somehow found space for a 2600mAh Li-Poly battery, a step-up regulator, and a charge circuit.

The result is a full-color RetroPi build capable of running for three hours before needing a recharge. All the classic Game Boy games are loaded onto the SD card along with select titles for other systems. The result is one of the best portabalized Raspi builds we’ve ever seen. Video below.
