The Nintendo PlayStation: Finally Working

May 6, 2017 by 19 Comments

The Nintendo PlayStation is not a misnomer. Before the PS1, Sony teamed up with Nintendo to produce a video game console that used CD-ROMs as a distribution platform. These plans fell through, Sony went on to design the PS1, Nintendo the N64, but a few prototype ‘Nintendo PlayStations’ made it out into the wild. One of these unbelievably rare consoles was shipped to a company that eventually went into bankruptcy. The console was found when the contents of an office building were put up for auction, and last year, [Ben Heck] tore it apart.

It’s taken a year, but now this Nintendo PlayStation is finally working. This console now plays audio CDs and games written by homebrewers. The hardware lives, and a console once forgotten lives once more.

The last time [Ben Heck] took a look at the Nintendo PlayStation, the CD-ROM portion of the console was non-functional. The Super Nintendo was still functional, but for this prototype, the CD-ROM was completely self-contained and required a ‘boot cartridge’ of sorts to access anything on a CD. Somehow or another — [Ben] thinks it was a wonky cable or a dead cap — The CD-ROM came to life. Yes, jiggling a cable was the extent of the repair, after spending an inordinate amount of time reverse engineering the console.

With the CD-ROM working, [Ben] got audio playing and tried out of the few homebrew games for this PlayStation prototype. Super Boss Gaiden didn’t quite work because this game was designed to load in chunks. Another game written for this console, Magic Floor, was small enough to fit in the entirety of the CD-ROM’s buffer and loaded correctly. That doesn’t mean the game worked; there are some slight differences between the Nintendo PlayStation emulator and the actual hardware that now exists. [Ben] emailed the author of Magic Floor, and now, after a quarter-century, the Nintendo PlayStation works.

What’s next for the Nintendo PlayStation? Well, now the emulator for this system can correctly reflect the actual hardware, and hopefully the homebrewers can figure out how to write a game for this system.

Reverse Engineering The Sony PocketStation

October 5, 2016 by 15 Comments

[Robson Couto] never actually owned a PlayStation in his youth, but that doesn’t mean he can’t have a later in life renaissance. In particular a Japan-only accessory called the PocketStation caught his interest.

The item in question resided in the PlayStation’s memory card slot. It’s purpose was to add additional functionality to games and hopefully sell itself. Like the PokeWalker, Kinect, etc. It’s an age old tactic but the PocketStation had some interesting stuff going on (translated).

The biggest was its processor. Despite having a pathetic 32×32 mono screen, it hosted the same processor as the GameBoy Advance. Having acquired a card from an internet auction house [Robson] wanted to load up some of the ROMs for this device and see what it was like.

It took quite a bit of work. Luckily there is a ton of documentation floating around the internet thanks to the emulation scene and it wasn’t long before he convinced a microcontroller to pretend to be the memory card slot. Now anyone with some skill and a small piece of gaming history can play around with the rare ROM dump for the PocketStation.

Vibrating gaming chair

Gaming Chair Gives Full Body Feeling To Collisions

May 21, 2016 by 18 Comments

A PS-3 controller has an unbalanced motor inside that vibrates your hand whenever you crash a car into a wall or drive it off a cliff and hit the rocks below but [Rulof Maker] wanted that same feeling all over his body. So he added a serious unbalanced motor to his favorite gaming chair to make his whole body vibrate instead.

To do that he opened up the controller and found the wires going to the unbalanced motor. There he added a small relay, to be activated whenever the motor was energized. Wires from that relay go to a female connector mounted in the side of the controller, keeping the controller small and lightweight.

Next he needed to attach a much bigger unbalanced motor to the underside of his favorite gaming chair. For the unbalanced mass he poured concrete powder and molten lead into a tin can mold and attached the result to the motor’s shaft. Using a piece of wood he attached the motor to the chair’s underside.

All that was left was to power the motor and turn it on when needed. For that he wired up a bigger relay, with the relay’s coil wired to a male connector to plug into the PS-3 controller. Now when the PS-3 wants to vibrate, that relay is energized. All that was left was to wire the relay’s normally open switch, the motor and a power cord in series, plug it into the wall socket, and he was ready to shake.

Hackaday Links: January 10, 2016

January 10, 2016 by 11 Comments

Everybody loves cheap stuff, and we hate telling everyone about coupon codes. That said, TI has a new LaunchPad development board they’re promoting. It’s based on the MSP432, the ARM extension of their MSP430 line. The MSP432 is an ARM Cortex M4F, low power, and planned for production later this year.

Here’s your daily CES garbage post. Through a collaboration between Sony and Nissan, a car has become a video game controller controller. A controller plugs into the ODB II port, reads throttle, brake, and steering wheel positions (and buttons on the dash/steering wheel, I guess), and translates that into controller input for a PlayStation 4. What games do they play with a car? You would think Gran Turismo, Rocket League, or other games with cars in them. Nope. Football.

Dangerous Prototypes is a legal Chinese company! [Ian] didn’t say anything about the process about becoming a legal Chinese company because he wrote a blog post, not a book. Shenzhen Dangerous Prototypes Electronics Technology Limited allows them to have an office in the Shenzhen electronics market, hire local and foreign hackers, host Hacker Camp Shenzhen, and allow people to apply for ‘Authorized Authority’ visa letters for the people who need them. Great news for a great company.

The Forge hackerspace in Greensboro, NC is growing. In just over a year they have 160 members and they’ve already outgrown their 3,400 square foot space. Now they’re moving to a larger space that’s twice the size and they’re looking for donations.

People have been taking old iPad screens and turning them into HDMI displays for years now. [Dave] got his mitts on a panel from a Macbook Pro 17″, and turned it into a monitor. It required a $50 LVDS adapter, but the end result is great – a 1920×1200 panel that looks pretty good.

PS4 NES

Add Extra Storage To Your PS4 With Retro Flair

February 5, 2015 by 14 Comments

[Frank] came up with a clever way to extend the storage of his PS4. He’s managed to store his digital PS4 games inside of storage devices in the shape of classic NES cartridges. It’s a relatively simple hack on the technical side of things, but the result is a fun and interesting way to store your digital games.

He started out by designing his own 3D model of the NES cartridge. He then printed the cartridge on his Ultimaker 3D printer. The final print is a very good quality replica of the old style cartridge. The trick of this build is that each cartridge actually contains a 2.5″ hard drive. [Frank] can store each game on a separate drive, placing each one in a separate cartridge. He then prints his own 80’s style labels for these current generation games. You would have a hard time noticing that these games are not classic NES games at first glance.

Storing the game in cartridge form is one thing, but reading them into the PS4 is another. The trick is to use a SATA connector attached to the PS4’s motherboard. [Frank’s] project page makes it sound like he was able to plug the SATA cable in without opening the PS4, by attaching the connector to a Popsicle stick and then using that to reach in and plug the connector in place. The other end of the SATA cable goes into a custom 3D printed housing that fits the fake NES cartridges. This housing is attached to the side of the PS4 using machine screws.

Now [Frank] can just slide the cartridge of his choice into the slot and the PS4 instantly reads it. In an age where we try to cram more and more bits into smaller and smaller places, this may not be the most practical build. But sometimes hacking isn’t about being practical. Sometimes it’s simply about having fun. This project is a perfect example. Continue reading “Add Extra Storage To Your PS4 With Retro Flair” →

PS3 Controller

Get Better At Mortal Kombat By Hacking Your PS3 Controller

January 24, 2015 by 12 Comments

Fighting games like Mortal Kombat provide you with a variety of different available moves. These include kicks, punches, grabs, etc. They also normally include various combination moves you can perform. These combo moves require you to press the proper buttons in the correct order and also require you to time the presses correctly. [Egzola] realized that he could just hack his controller to simulate the button presses for him. This bypasses the learning curve and allows him to perform more complicated combinations with just the press of a single button.

[Egzola] started by taking apart his Playstation 3 controller. There were two PCB’s inside connected by a ribbon cable. Luckily, each individual pad for this cable was labeled with the corresponding controller button. This made it extremely simple to hack the controller. [Egzola] soldered his own wires to each of these pads. Each wire is a different color. The wires then go to two different connectors to make them easier to hook up to a bread board.

Each wire is then broken out on the breadboard. The signal from each button is run through a 4n25 optoisolator. From there the signal makes its way back to various Arduino pins. The 4n25 chips keeps the controller circuit isolated from the Arduino’s electrical circuit. The Arduino also has two push buttons connected to it. These buttons are mounted to the PS3 controller.

Now when [Egzola] presses one of the buttons, the Arduino senses the button press and simulates pressing the various controller buttons in a pre-programmed order. The result is a devastating combination move that would normally require practice and repetition to remember. You might say that [Egzola] could have spent his time just learning the moves, but that wasn’t really the point was it? Check out the video below for a demonstration.

College Researcher Makes Supercomputer From 420 PS3s

December 28, 2014 by 64 Comments

Noting that funding for science has run dry for many researchers, [Gaurav] has built a supercomputer from 200 Playstation 3 consoles housed and chilled inside an old refrigerated shipping trailer. His mission at UMass Dartmouth from the National Science Foundation is simulating black hole collisions with an eye on learning something about gravitational waves.

Dr. [Gaurav Khanna] is no stranger to using PS3 supercomputers to do meaningful science. Seven years ago he proposed a 16-PS3 supercomputer running Linux and managed to convince Sony to donate four consoles. The university kicked in funding for another 8 and [Gaurav] ponied up for the last four out of his own pocket. He dubbed it the “PS3 Gravity Grid” and received international attention for the cluster. For equivalent performance, it cost him only 10% the price of a real supercomputer. This led to published papers on both hacked supercomputers and gravity waves. But that rig is looking a little old today. Enter the Air Force.

Dr. [Khanna] was not the only one using PS3s to crunch data – back in 2010 the US Air Force built the “Condor Cluster” of 1,760 PS3s to perform radar imaging of entire cities and do neuromorphic AI research. With their hardware now expired, the Air Force donated 200 of the PS3s to [Gaurav] for his new build. Now that he has wired them up, the Air Force is donating another 220 for a not-snicker-proofed total of 420.

For those sceptical that the now 8-year-old hardware is still cost-effective, even with free consoles it is marginal. RAM is an issue and modern graphics cards are each equivalent to 20 PS3s. Ever the popular target these days, Sony has the PS4 OS locked down from the get go – thanks Sony. The next cluster planned will be with PCs and graphics cards. For now, [Gaurav] has plenty of calculations that need crunching and a queue of colleagues have formed behind him.
