Playstacean Evolves The PSOne Into The Crab It Was Always Meant To Be

April 3, 2025 by Navarre Bartz 6 Comments

Odd hardware designs crop up in art and renders far more frequently than in the flesh, but console modder [GingerOfOz] felt the need to bring [Anh Dang]’s image of the inevitable carcinization of our gaming consoles to life.

Starting with the image as inspiration, [GingerOfOz] got to work in CAD, creating an entirely new shell for the battered PSOne he adopted for the project. The final product is slightly less curvy than the picture, but some artistic license was necessary to go from the page to the real world.

The enclosure itself looks straightforward, if a bit tedious, but the articulating crab controller is a work of art itself. He could’ve made the arms static or non-functional, but they’re a fully-functional PlayStation controller that can move around just like on your favorite crustacean at the beach, minus the pinching. We love this whimsical take on the console mod which is a breath of salty air to the continuous race to get increasingly complex consoles into handheld form, although there’s certainly nothing wrong with that!

If you’re looking for some other console mods, how about this Apple M1 inside a Wii or getting your old Ouya up-and-running again?

Handheld Console Plays Original Pong With Modern E-Waste

March 24, 2025 by Donald Papp 8 Comments

[Simon] wrote in to let us know about DingPong, his handheld portable Pong console. There’s a bit more to it than meets the eye, however. Consider for a moment that back in the 1970s playing Pong required a considerable amount of equipment, not least of which was dedicated electronics and a CRT monitor. What was huge (in more than one way) in the 70s has been shrunk down to handheld, and implemented almost entirely on modern e-waste in the process.

The 1970s would be blown away by a handheld version of Pong, made almost entirely from salvaged components.

DingPong is housed in an old video doorbell unit (hence the name) and the screen is a Sony Video Watchman, a portable TV from 1982 with an amazing 4-inch CRT whose guts [Simon] embeds into the enclosure. Nearly everything in the build is either salvaged, or scrounged from the junk bin. Components are in close-enough values, and power comes from nameless lithium-ion batteries that are past their prime but still good enough to provide about an hour of runtime. The paddle controllers? Two pots (again, of not-quite-the-right values) sticking out the sides of the unit, one for each player.

At the heart of DingPong one will not find any flavor of Arduino, Raspberry Pi, or ESP32. Rather, it’s built around an AY-3-8500 “Ball & paddle” (aka ‘Pong’) integrated circuit from 1977, which means DingPong plays the real thing!

We have seen Pong played on a Sony Watchman before, and we’ve also seen a vintage Pong console brought back to life, but we’re pretty sure this is the first time we’ve seen a Sony Watchman running Pong off a chip straight from the 70s. Watch it in action in the video (in German), embedded below.

Homebrew Retro Console Runs On PIC32

January 13, 2025 by Lewin Day 9 Comments

[Chad Burrow] decided to take on a noble task—building a “retro” style computer and video game console. Only, this one is built using somewhat modern hardware—relying on the grunt of the PIC32MZ2048EFH144 to get the job done. Meet the Acolyte Hand PIC’d 32.

It’s name might be a mouthful, but that chip can pull off some great feats! With a clock speed of 200 MHz, it’s not short on processing power, though RAM and flash storage are somewhat limited at just 512 KB and 2MB respectively. [Chad] was able to leverage those constraints to get a VGA output working at a resolutions up to 800 x 600, with up to 65,000 colors—though 256 colors is more practical due to memory concerns. The Acolyte Hand also rocks two 8-bit audio channels. It has a pair of Genesis-compatible controller ports as well as PS/2 and USB for keyboards and mice, along with more modern Xbox 360 controllers.

[Chad] cooked up some software to put it through its paces, too. It’s got a Tetris clone on board, and can also run Game Boy games at full speed via the Peanut-GB emulator. That provides for a pretty rich game library, though [Chad] notes he plans to develop more native video games for his system to demo at his local college. Design files are on Github for the curious.

This project is a great example of just how powerful modern microcontrollers have become. Once upon a time, just driving a simple black-and-white graphical LCD might have taken some real effort, but today, there are pixels and clock cycles to spare in projects like these. Truly a wonderous world we live in!

The Phantom PSP: Crafting The Handheld Sony Never Sold

November 2, 2024 by Heidi Ulrich 7 Comments

In the world of retro gaming, some legends never die – especially the ‘phantom’ PSP, Sony’s mythical handheld that never saw the light of day. While that elusive device remains a dream, hacker and gaming wizard [Kyle Brinkerhoff] built his own – and Macho Nacho made a video about it. His creation, which also goes by the name ‘Playstation Zero’, isn’t just another handheld emulator; it’s a powerful, custom-built system that revives the classics and plays them on a portable device that feels like the future.

Driven by a hunger for the ultimate gaming experience, [Kyle] set out to blend modern tech with retro gaming magic. He started with the Raspberry Pi, loading it up with emulation software for all the iconic systems—from NES and SNES to the Sega Genesis and Game Boy. But [Kyle] didn’t just slap on an off-the-shelf emulator; he dived into the code himself, optimizing and tweaking for lightning-fast responsiveness, so each game plays like it’s running on the original hardware. That’s hacking in true form: pushing the limits of software and hardware until they work exactly the way you want them to. Best of all: he published it all open source for others to use.

In the spirit of the Geneboy—a handheld Sega Genesis built by [Downing] and featured on Hackaday back in 2012—[Kyle]’s device pairs handheld emulation with the consoles all nineties kids wanted for Christmas. To capture the tactile thrill of vintage gaming, [Kyle] went a step further by designing and 3D-printing a custom controller layout that mimics the feel of the original systems. If watching someone neatly soldering a pcb sounds relaxing to you, don’t skip the middle part of his video. Although this little beast is packed with all bells and whistles you’d expect to see on a Raspberry Pi, it does lack one serious thing: battery life. But, [Kyle] is open about that, and hopes to improve on that in a future version.

If you want to see the full build, check out the video below. Or, immediately dive into [Kyle]’s Github, order the cute Takara shell, and get started!

Supercon 2023: Building A Portable Vectrex, The Right Way

October 24, 2024 by Lewin Day 16 Comments

The Vectrex was a unique console from the early 1980s. Developed by a company you’ve probably never heard of—Smith Engineering—it was put into production by General Consumer Electronics, and later sold by Milton Bradley. It was an outright commercial failure, but it’s remembered for its sharp vector display and oddball form factor.

The Vectrex was intended for tabletop use in a home environment. However, [Jeroen Domburg], also known as [Sprite_tm], decided to set about building a portable version. This wasn’t easy, but that just makes the development process a more interesting story. Thankfully for us, [Sprite_tm] was kind enough to tell the tale at the 2023 Hackaday Supercon.

Ryobi Battery Pack Gives Up Its Secrets Before Giving Up The Ghost

August 14, 2024 by Dan Maloney 44 Comments

Remember when dead batteries were something you’d just toss in the trash? Those days are long gone, thankfully, and rechargeable battery packs have put powerful cordless tools in the palms of our hands. But when those battery packs go bad, replacing them becomes an expensive proposition. And that’s a great excuse to pop a pack open and see what’s happening inside.

The battery pack in question found its way to [Don]’s bench by blinking some error codes and refusing to charge. Popping it open, he found a surprisingly packed PCB on top of the lithium cells, presumably the battery management system judging by the part numbers on some of the chips. There are a lot of test points along with some tempting headers, including one that gave up some serial data when the battery’s test button was pressed. The data isn’t encrypted, but it is somewhat cryptic, and didn’t give [Don] much help. Moving on to the test points, [Don] was able to measure the voltage of each battery in the series string. He also identified test pads that disable individual cells, at least judging by the serial output, which could be diagnostically interesting. [Don]’s reverse engineering work is now focused on the charge controller chip, which he’s looking at through its I2C port. He seems to have done quite a bit of work capturing output and trying to square it with the chip’s datasheet, but he’s having trouble decoding it.

This would be a great place for the Hackaday community to pitch in so he can perhaps get this battery unbricked. We have to admit feeling a wee bit responsible for this, since [Don] reports that it was our article on reverse engineering a cheap security camera that inspired him to dig into this, so we’d love to get him some help.

Building A Keychain Wii Looks Possible

July 26, 2024 by Lewin Day 10 Comments

The original Nintendo Wii was not a big console, per se, but you could never hope to fit one in your pocket. Or…could you? As it turns out, console modders [Wesk] and [Yveltal] reckon they have found a way to make a functional Wii at the keychain scale!

The concept is called the Kawaii, and as you might expect, some sacrifices are necessary to get it down to pocketable size of 60 x 60 x 16 mm. It’s all based around the “Omega Trim,” an established technique in the modding community to cut a standard Wii motherboard down to size. Controllers are hooked up via a dock connection that also provides video out. There’s no Bluetooth, so Wiimote use is out of the question. You can still play some Wii games with GameCube Controllers by using GC2Wiimote, though. The Wii hardware is under-volted to allow for passive cooling, too, with an aluminum enclosure used to shed heat. Custom PCBs are used to handle power and breakouts, which will be open sourced in due time.

The forum post featured an expression of interest for those eager to order aluminium enclosures to pursue their own Kawaii build. Slots quickly filled up and the EOI was soon closed.

As of now, the Kawaii is still mostly conceptual, with images being very compelling renders. However, it relies on established Wii modding techniques, so there shouldn’t be any shocking surprises in the next stage of development. Expect to see finished Kawaii builds in gorgeous machined aluminum housings before long.

We’ve seen some other great Wii portables over the years. The console remains cheap on the used market and was built in great numbers. Thus, it remains the perfect platform for those eager to get their feet wet in the console modding community!
