Slide Your Switch Into A Gamecube Controller

May 2, 2020 by 7 Comments

The Gamecube was certainly a divisive design when it was released back in 2001, but the fact that people are still happily hacking away at its controller nearly 20 years later proves that Nintendo must have gotten something right. The latest project from Nintendo wizard [Bill Paxton] turns the unique Gamecube controller into an even more unique mobile dock for the Switch.

To build this “Gamecube Grip”, [Bill] literally cut an original controller and its PCB in half so they could be relocated on either end of the 3D printed central frame. Internally, the controller PCB is wired up to a GC+ board, which is an open hardware project that uses a PIC18F25K22 microcontroller to bring enhanced features to the classic peripheral such as adjustable stick dead zones and rumble intensity. From there, it’s connected to the switch with a GBros adapter from 8bitdo.

The grip also includes an Anker PowerCore 20,100 mAh battery that should keep the system going for hours, and some components liberated from a third party Switch dock. Everything has been finished off with the attention to detail that we’ve come to expect from [Bill] and his projects, including the seemingly flawless glossy paint job that’s something of hallmark for his custom gaming creations.

Putting An Arcade Cabinet Inside Of An NES Controller

May 1, 2020 by 23 Comments

The arcade game shoehorned into an original Nintendo Entertainment System controller from [Taylor Burley] is certainly made slightly easier by its starting with one of those miniature cabinets that are all the rage now, but since he’s still achieved the feat of an entire arcade game in a controller we still stand by the assessment in our title.

In fact, he’s put not one but four arcade games into the controller. The board that [Taylor] liberated from the miniature game system can actually be switched between the onboard games by shorting out different pads on the PCB. Normally this would be done during manufacture with a zero-ohm resistor, but in this case, he’s wired the pads out to a strip of membrane keypad liberated from an LED remote control. By holding a different button while powering on the system, the user can select which of the games they want to boot into.

The original buttons and directional pad have been preserved, and in the video after the break, [Taylor] shows how he wires them into the arcade PCB. The Start and Select buttons had to go since that’s where the tiny color LCD goes now, but they wouldn’t have been used in any of these games anyway. With the addition of a small battery pack and charge controller, this build is a clever way to take several classic arcade titles with you on the go.

With the growing popularity of these tiny arcade cabinets, we’ve seen a number of hackers tearing into them. The work that [wrongbaud] has done in modifying them to run other ROMs is not to be missed if you’re looking at building a project using one of these little bundles of nostalgia.

Nintendo Switch Built Completely From Replacement Parts

April 15, 2020 by 20 Comments

It seems that everybody around us is playing Animal Crossing New Horizons, and we’re not alone in this. But a new Nintendo Switch can’t be had for love nor money, and second hand ones have fallen victim to price gouging. It seems if you’re not playing the game, you’re out of luck, or are you?

What’s to be done? [Sarbaaz37] found the hardware hacker’s solution to that question: Build a Nintendo Switch entirely from spare parts, of course! It took a month to source the parts and it’s not a project for the fainthearted, but it provides us with a look at all the parts they pack into the handheld. All told, there’s about 22 part numbers in the bill of materials.

Anyone who has peeked inside a laptop recently will be familiar with the arrangement of this type of device. An array of extremely snug-fitting and fragile electronics laid out like a TV dinner has to be carefully assembled in a specific order and this is no different. Along the way [Sarbaaz37] has some pro tips, like cleaning off the stock thermal compound and using a higher quality. The eventual result is a working Switch, which for $200 is not a bad deal, though they do note that the pandemic has since led to a price rise in Nintendo parts as well as consoles.

This is, we think, the first home-made Switch we’ve seen, but it’s not the first desirable piece of consumer electronics made from grey market parts we’ve seen. Who could forget the Shenzhen electronics markets adventure of sourcing all the parts that go into an iPhone?

Thanks [Roel] for the tip.

Trimmed PCB Makes The Ultimate Portable N64

March 27, 2020 by 2 Comments

One of the most impressive innovations we’ve seen in the world of custom handhelds is the use of “trimmed” PCBs. These are motherboards of popular video game consoles such as the Nintendo Wii and Sega Dreamcast that have literally been cut down to a smaller size. As you can imagine, finding the precise shape that can be cut out before the system stops functioning requires extensive research and testing. But if you can pull it off, some truly incredible builds are possible.

Take for example this absolutely incredible clamshell N64 built by [GMan]. After cutting the motherboard down to palm-sized dimensions, he’s been able to create a handheld system that’s only a bit larger than the console’s original cartridges.

Incidentally those original cartridges are still supported, and fit into a slot in the rear of the system Game Boy style. It’s still a bit too chunky for tossing in your pocket, but we doubt you could build a portable N64 any smaller without resorting to emulation.

In the video after the break, [Gman] explains that the real breakthrough for trimmed N64s came when it was found that the system’s Peripheral Interface (PIF) chip could be successfully relocated. As this chip was on the outer edge of the PCB, being able to move it meant the board could get cut down smaller than ever before.

But there’s more than just a hacked N64 motherboard living inside the 3D printed enclosure. [Gman] also designed a custom PCB that’s handling USB-C power delivery, charging the handheld’s 4250 mAh battery, and providing digital audio over I2S. It’s a fantastically professional setup, and you’d be forgiven for thinking the board was part of the original console.

Considering how well designed and built this N64 SP is, it probably will come as no surprise to find this isn’t the first time [Gman] has put something like this together. He used many of the same tricks to build his equally impressive portable Dreamcast last year.

A NES Motherboard For The Open Source Generation

March 22, 2020 by 36 Comments

As the original hardware from the golden era of 8-bit computer gaming becomes a bit long in the tooth, keeping it alive has become something of a concern for enthusiasts. There have been a succession of remanufactured parts for many of the major platforms of the day, and now thanks to [Redherring32] it’s the turn of the NES console.

The OpenTendo is a completely open-source replacement for an original front-loading Nintendo Entertainment System motherboard, using both original or after-market Nintendo CPU and PPU chips, and other still readily available components. It doesn’t incorporate Nintendo’s CIC lockout chip — Drew Littrell wrote a great article on how that security feature worked — but if you really need the authenticity there is also the NullCIC project that can simulate that component.

It’s an interesting exercise in reverse engineering as well as a chance to look at the NES at the chip level. Also for Nintendo-heads, it provides all the component footprints and schematic items in KiCAD format. Will many be built? Given that the NES was the best-selling console of its time there should be no shortage of originals to be found, but that in no way invalidates the effort put into this project. There will be NES consoles somewhere running for decades to come because of work such as this, simply remember that you don’t need to blow in the slot to make it work!

There Really Was A Sewing Machine Controlled By A Game Boy

March 11, 2020 by 12 Comments

These days, high-quality displays and powerful microcontrollers are cheap and plentiful. That wasn’t the case a couple of decades ago, and so engineers sometimes had to get creative. The result of this is products like the Jaguar nu.yell sewing machine, as covered by [Kelsey Lewin].

The later nuotto model was capable of more advanced embroidery patterns. A Mario character cartridge was sold, while a later Kirby edition was scrapped before release.

The Japanese market product eschewed the typical mechanical controls of the era, to instead interface with a Nintendo Game Boy. The sewing machine would hook up to the handheld console via the Link Port, while the user ran a special cartridge containing the control software. This would allow the user to select different stitch types, or embroider letters. Very much a product of its time, the nu yell mimics the then-cutting edge industrial design of the first-generation Apple iMac. The technology was later licensed to Singer, who brought it to the US under the name IZEK. Sales were poor, and the later Jaguar nuotto didn’t get a similar rebranding stateside.

Back in the late 90s, the Game Boy was likely an attractive package to engineers. Packing a Z80 processor, buttons, and a screen, it could act as a simple human interface in lieu of designing one from the ground up.  Aprilia even used them to diagnose motorbike ECUs, and we’ve seen Game Boy parts used in medical hardware from the era, too. Video after the break.

Ultra-Rare Nintendo Play Station Prototype Hits Auction Block

February 13, 2020 by 26 Comments

If you are interested in such things, you can buy a 1990s Sony Play Station via Heritage Auctions. We’re sure this will have caught your interest, after all it’s not every day you get the chance to catch such a machine. But before you call us out for seemingly reporting the news of an unremarkable sale featuring the runaway success story of 1990s gaming, take a look at the first sentence again. This is not a PlayStation, the ubiquitous grey console of the 1990s, but a Play Station, said as two words rather than one. This ill-fated collaboration between Sony and Nintendo was intended to be an SNES with a CD-ROM drive, but the project faltered and all that remained was the almost mythical tale of a few prototype consoles.

So far there has only been one of these devices that has surfaced, and this is the machine in the auction. So what seemed as though it might be a mundane console turns out to be one of the rarest machines ever created, a true Holy Grail of console collecting.

This machine has a known provenance, and has appeared on these pages before. In 2016 Ben Heck did a teardown to reveal the combination of Sony CD drive and SNES motherboard, and by 2017 he had it working with some homebrew games. There was no official software produced for this console, so it seems the lucky purchaser may have only homebrew games with which to try their console.

At the time of writing the auction is standing at $57,600, and we’d expect this to increase significantly. So you may not have the chance to own the Play Station, but with such a rare machine it’s always worth noting its appearances. It’s also worth remembering that there was more than one of them produced, in fact when your scribe was working in the same industry in the 1990s a senior colleague talked about having been shown one during dealings with Nintendo UK a few years earlier. The machine on sale today may be the only one we know to have survived, but it’s a fair possibility that there are others still gathering dust in long-forgotten archive boxes or collections of gaming hardware junk. Keep an eye out, you might just find your own rarest console ever produced!
