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?

3D-Printed Scanner Automates Deck Management For Trading Card Gamers

March 26, 2025 by Dan Maloney 12 Comments

Those who indulge in trading card games know that building the best deck is the key to victory. What exactly that entails is a mystery to us muggles, but keeping track of your cards is a vital part of the process, one that this DIY card scanner (original German; English translation) seeks to automate.

At its heart, [Fraens]’ card scanner is all about paper handling, which is always an engineering task fraught with peril. Cards like those for Magic: The Gathering and other TCGs are meant to be handled by human hands, and automating the task of flipping through them presents some challenges. [Fraens] uses a pair of motorized 3D-printed rollers with O-rings to form a conveyor belt that can pull one card at a time off the bottom of a deck. An adjustable retaining roller made from the most adorable linear bearing we’ve ever seen ensures that only one card at a time is pulled from the hopper onto an imaging platen. An adjustable mount holds a smartphone to take a picture of the card, which is fed into an app that extracts all the details and categorizes the cards in the deck.

Aside from the card handling mechanism, there are some pretty slick details to this build. The first is that [Fraens] noticed that the glossy finish on some cards interfered with scanning, leading him to add a diffused LED ringlight to the rig. If an image isn’t scannable, the light goes through a process of dimming and switching colors until a good scan is achieved. Also, to avoid the need to modify the existing TCG deck management app, [Fraens] added a microphone to the control side of the scanner that listens for the sounds the app makes when it scans cards. And if Magic isn’t your thing, the basic mechanism could easily be modified to scan everything from business cards to old family photos.

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.

The SNES Seems To Be Getting Faster Over Time

March 24, 2025 by Zoe Skyforest 24 Comments

Every Super Nintendo console should run at the same speed. They were all built in factories with the same components so they should all operate at the steady clip mandated by Nintendo all those years ago. Except, apparently, the SNES is speeding up as it gets older.

The matter was brought to the public’s attention by the [TASBot] team, a group within the speedrunning community. If anyone was going to notice vintage consoles suddenly running a hair faster, you could bet it would be the speedrunners. Soon enough, a call was put out to crowdsource some data. Submitters were asked to run a set piece of code to test the DSP sample rate on consoles when cold and warm, to get the best idea of what was going on.

As reported by Ars Technica, the group seems to have pinned down the problem to the SNES’s Audio Processing Unit. It’s supposed to run at 24.576 MHz, with a sample rate of 32,000 Hz. However, over the years, emulator developers and speedrunners had noticed that 32,040 Hz seemed to be a more realistic figure for what real consoles were actually running the DSP sample rate at. Developers found that building emulators to run the DSP at this rate was important to run commercial games as expected, suggesting the hardware might have always been a little faster than expected.

However, more recently, it seems that the average speed of the DSP sample rate has increased further. The average result collected by [TASBot] from modern consoles is 32,076 Hz. What’s more interesting is the range of submitted figures—from 31,976 Hz to 32,349 Hz. It seems that the DSP’s ceramic resonator—used instead of a quartz crystal—might degrade over time, causing the speedup. [TASBot] team members also tested temperature changes, but only found a 32 Hz variation from a frozen SNES to one at room temperature.

The fact that console components degrade over time isn’t exactly news; we’ve featured plenty of articles on leaky batteries and corroded traces. Still, for speedrunners, the idea that the hardware standard itself can shift over time? It’s like feeling quicksand under your feet. What even is reality anymore?

Build A Starship Bridge Simulator With EmptyEpsilon

March 23, 2025 by Maya Posch 30 Comments

Who hasn’t dreamed of serving on the bridge of a Star Trek starship? Although the EmptyEpsilon project isn’t adorned with the Universe-famous LCARS user interface, it does provide a comprehensive simulation scenario, in a multiplayer setting. Designed as a LAN or WAN multiplayer game hosted by the server that also serves as the main screen, four to six additional devices are required to handle the non-captain tasks. These include helm, weapons, engineering, science and relay, which includes comms.

Scenarios are created by the game master, not unlike a D&D game, with the site providing a reference and various examples of how to go about this.

The free and open source game’s binaries can be obtained directly from the site, but it’s also available on Steam. The game isn’t limited to just Trek either, but scenarios can be crafted to fit whatever franchise or creative impulse feels right for that LAN party.

Obviously building the whole thing into a realistic starship bridge is optional, but it certainly looks like more fun that way.

Building A Handheld Pong Game

March 21, 2025 by Zoe Skyforest 2 Comments

Pong was one of the first video games to really enter the public consciousness. While it hasn’t had the staying power of franchises like Zelda or Call of Duty, it nonetheless still resonates with gamers today. That includes [Arnov Sharma], who put together this neat handheld version using modern components.

An ESP32 development board serves as the brains of the operation. Capable of operating at many hundreds of megahertz, it has an excessive amount of power for an application as simple as this. Nonetheless, it’s cheap, and it gets the job done. It’s paired with an SSD1306 OLED screen of 124 x 32 resolution. That might not sound like much, but it’s plenty when you’re just drawing two paddles and a ball bouncing between them. Control is via a pair of SMD push buttons for a nice responsive feel.

What’s really neat, though, is the presentation. [Arnov] wrapped the electronics in a neat bean-shaped housing that vaguely apes game controllers of the 16-bit era. Indeed, [Arnov] explains that it was inspired by the Sega Genesis specifically. It looks great with the black PCBs integrated so nicely with the bright orange 3D printed components, and looks quite comfortable to use, too.

It might be a simple project, but it’s done rather well. Just by thinking about color choices and how to assemble the base components, [Arnov] was able to create an attractive and functional game that’s a lot more eye catching than some random boards thrown in an old project box. Indeed, we’ve featured stories on advanced FR4/PCB construction techniques before, too. Meanwhile, if you’re creating your own projects with similar techniques, don’t hesitate to let us know!

This M5Stack Game Is Surprisingly Addictive

March 19, 2025 by Jenny List 5 Comments

For those of us lucky enough to have been at Hackaday Europe in Berlin, there was a feast of hacks at our disposal. Among them was [Vladimir Divic]’s gradients game, software for an M5Stack module which was definitely a lot of fun to play. The idea of the game is simple enough, a procedurally generated contour map is displayed on the screen, and the player must navigate a red ball around and collect as many green ones as possible. It’s navigated using the M5Stack’s accelerometer, which is what makes for the engaging gameplay. In particular it takes a moment to discover that the ball can be given momentum, making it something more than a simple case of ball-rolling.

Underneath the hood it’s an Arduino .ino file for the M5Stack’s ESP32, and thus shouldn’t present a particular challenge to most readers. Meanwhile the M5Stack with its versatile range of peripherals has made it onto these pages several times over the years, not least as a LoRA gateway.
