Raspberry Pi Compute Module 3 In A GameBoy Original

November 17, 2017 by Bryan Cockfield 5 Comments

[Kite] has been making custom PCBs for GameBoys for a long time. Long enough, in fact, that other people have used his work to build even more feature-rich GameBoy platforms. Unfortunately some of their work had stagnated, so [Kite] picked it up and completed a new project: a GameBoy that uses a Raspberry Pi running on his upgraded GameBoy PCB.

At its core the build uses a Raspberry Pi 3, but one that has been shrunk down to the shape of a memory module, known as the Compute Module 3. (We featured the original build by [inches] before, but [Kite] has taken it over since then.) The upgrade frees up precious space in the GameBoy case to fit the custom PCB that was originally built by [Kite], and also eliminates the need to cut up a Raspberry Pi and solder it to the old version of his PCB. The build is very clean, and runs RetroPie like a champ. It has some additional features as well, such as having an HDMI output.

For anyone looking for that retro GameBoy feel but who wants important upgrades like a backlit color screen, or the ability to play PSP games, this might be the build for you. The video below goes into details about how it all fits together. If you’re looking for more of a challenge in your GameBoy hacks, though, there’s an ongoing challenge to build the tiniest GameBoy possible as well.

Why Only Use One Controller When You Can Use ALL Of Them?

October 28, 2017 by James Hobson 8 Comments

After booting up his RetroPie system, [jfrmilner] had the distinct feeling that something was off. Realizing that the modern Xbox 360 controller didn’t fit right when reliving the games of his youth, he rounded up all his old controllers to make sure he always had the right gamepad for the game.

Wanting to keep the controllers unmodified — so they could still be used on the original systems — he had to do a bit of reverse-engineering and source some controller sockets before building his controller hub. Using shift-in registers, shift-out registers, and some multiplexers, he designed a large circuit selector — which acts as a shield for an Arduino Micro — so all the controllers remain connected. A potentiometer allows him to select the desired controller and a few arcade buttons which access RetroPie shortcuts really round out the hub. Check out the demo after the break!

DIY Nintendo Switch May Be Better Than Real Thing

October 20, 2017 by Tom Nardi 20 Comments

Nintendo’s latest Zelda-playing device, the Switch, is having no problems essentially printing money for the Japanese gaming juggernaut. Its novel design that bridges the gap between portable and home console by essentially being both at the same time has clearly struck a chord with the modern gamer, and even 8 months after its release, stores are still reporting issues getting enough of the machines to meet demand.

But for our money, we’d rather have the Raspberry Pi powered version that [Tim Lindquist] slaved over for his summer project. Every part of the finished device (which he refers to as the “NinTIMdo RP”) looks professional, from the incredible job he did designing and printing the case down to the small details like the 5 LED display on the top edge that displays volume and battery level. For those of you wondering, his version even allows you to connect it to a TV; mimicking the handheld to console conversion of the real thing.

[Tim] has posted a fascinating time-lapse video of building the NinTIMdo RP on YouTube that covers every step of the process. It starts with a look at the 3D model he created in Autodesk Inventor, and then goes right into the post-printing prep work where he cleans up the printed holes with a Dremel and installs brass threaded inserts for strength. The bulk of the video shows the insane amount of hardware he managed to pack inside the case, a true testament to how much thought was put into the design.

For the software side, the Raspberry Pi is running the ever popular RetroPie along with the very slick EmulationStation front-end. There’s also a Teensy microcontroller on board that handles the low-level functions such as controlling volume, updating the LED display, and mapping the physical buttons to a USB HID device the Raspberry Pi can understand.

The Teensy source code as well as the 3D models of the case have been put up on GitHub, but for a project like this that’s just the tip of the iceberg. [Tim] does mention that he’s currently working on creating a full build tutorial though; so if Santa doesn’t leave a Switch under the tree for you this year, maybe he can at least give you a roll of filament and enough electronics to build your own.

While this isn’t the first time a Raspberry Pi has dressed up as a Nintendo console, it may represent the first time somebody has tried to replicate a current-generation gaming device with one.

Vintage Portable TV Turned Retro Gaming System

May 11, 2017 by Rich Hawkes 14 Comments

When [FinnAndersen] found an old TV set by the side of the road, he did what any self-respecting DIY/gaming enthusiast would do: He took it apart and installed a Raspberry Pi 3 running RetroPie in it in order to play retro games on a retro TV!

[Finn] took the CRT out of the TV before realizing that it actually worked. It was already too late, so [Finn] ordered a 12″ LCD screen to put in its place. He liked the idea of the curved screen the CRT had, though, so he molded a piece of acrylic around the CRT and, after some cutting and grinding, had it fitting in the screen’s space.

[Finn] also liked the idea of the TV still being able to view a television signal, so he bought a TV tuner card. After a couple of mods to it, he could control the card with the TV’s original channel changer. He used an Arduino to read the status of the rotary encoders the original TV used. After some trial and error, [Finn] was able to read the channel positions and the Arduino would send a signal to the channel up and down buttons on the tuner card in order to change the channel.

Next up was audio. [Finn] found a nicer speaker than came with the TV, so he swapped them and added an amplifier. The original volume knob is still used to control the volume. A USB Hub is hidden in the side of the TV at the bottom, to allow controllers to connect and finally, a power supply converts the mains voltage to 12V DC which runs both the Raspberry Pi and the TV Tuner.

[FinnAndersen] has built a great RetroPie cabinet reusing a great looking vintage TV. It’s unfortunate that he removed the CRT before figuring out that he could use it, but the replacement looks pretty darn good! And the added advantage? It’s portable, sort of. At least, without the CRT inside, it’s much lighter than it was. Here‘s another retro console inside an old TV, and this article is about connecting a Raspberry Pi to every display you can get your hands on.

This Hacker Fit An Entire RetroPie In An Altoids Tin

April 23, 2017 by Brian Benchoff 29 Comments

A few months ago, [wermy] built the mintyPi, a Raspberry Pi-based gaming console that fits inside an Altoids tin. It’s amazing — there’s a composite LCD, an audio DAC, and a chopped up Nintendo controller all connected to a Raspberry Pi for vintage gaming goodness on the road. Now, there’s a new mintyPi. The mintyPi 2.0 vastly improves over the earlier generation of this groundbreaking mint-based gaming console with a better screen, better buttons, customized 3D printed bezels, and better audio. Truly, we live in a Golden Age.

Version two of mintyPi uses 3D printed parts and includes a real hinge to keep the display propped up when the Altoids tin is open. Instead of a DAC-based audio solution, [wermy] is using a USB sound card for clearer, crisper sound. This version also uses the new, wireless version of the Raspberry Pi Zero. The Raspberry Pi Zero W allows this Altoids tin to connect to the Internet or, alternatively, gives the user the ability to dump ROMs on this thing without having to connect it to a computer.

For the software, this retro Altoids video game machine is running RetroPie, a very popular way to get retro video games running under low-power Linux machines. Everything is in there, from the NES to Amstrad to the Sega Master system.

Right now, there aren’t a whole lot of details on how [wermy] created the mintyPi 2.0, but he promises a guide soon. Until then, we’ll just have to drool over the video embedded below.

Portable RetroPie Suitcase For Multiplayer On The Go!

March 5, 2017 by James Hobson 11 Comments

Portable gaming — and gaming in general — has come a long way since the days of the original Game Boy. With a mind towards portable multiplayer games, Redditor [dagcon] has assembled a RetroPie inside a suitcase — screen and all!

This portable console has almost everything you could need. Four controllers are nestled beside two speakers. Much of the power cabling is separated and contained by foam inserts. The screen fits snugly into the lid with a sheet of rubber foam to protect it during transport.

Tucked behind the monitor rests the brains of this suitcase console: a Raspberry Pi and the associated boards. [Dagcon] resorted to using a dedicated sound card for the speakers, diverting the output from the HDMI port. An LCD screen controller was also necessary as the screen had been re-purposed from its previous life as a laptop screen. [Dagcon] offers some tips on how to go about accomplishing this yourself and a helpful Instructables link.

IPad Tossed Out For RetroPie Arcade Cabinet Redux

March 2, 2017 by Donald Papp 11 Comments

The naming and remixing in this project can get a little confusing to those unfamiliar with the different elements involved, but what [John Gerrard] has done is take a stylish mini arcade cabinet intended as a fancy peripheral for an iPad and turned it into an iPad-free retro arcade gaming cabinet. He also designed his own power controller for graceful startup and shutdown.

The project started with a peripheral called the iCade (originally conceived as a fake product for April Fool’s) and [John] observed it had good remix potential for use as a mini retro gaming cabinet. It was a good starting point: inexpensively purchased off eBay with suitable arcade-style joystick and buttons, a nice layout, and plenty of hacking potential. With a small variety of hardware from familiar sources like eBay and Aliexpress, [John] rounded up most of what he needed.
