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.

The Nixie Tube Multimeter That Almost Made A Comeback

November 1, 2024 by Heidi Ulrich 3 Comments

In a world of digital monotony, the Avo DA14 digital multimeter, with its vintage nixie tube charm, is a refreshing gem. Recently refurbished by [Thomas Scherrer], this multimeter video review is a blend of nostalgia and tech savvy. The DA14 not only has style, but substance — delivering resistance, current, and voltage measurements that make you wonder why more multimeters didn’t stick with this stylish glow.

As [Thomas] starts by powering up the DA14, we were instantly captivated as the Nixie tubes illuminate in their retro orange. With each twist of the dial, he demonstrates just how intuitive the multimeter is to operate, walking us viewers through each function while giving some extra love to its calibration process—a neat front-panel potentiometer that requires just a touch of finesse to get perfect readings.

But, as with all good tinkering tales, things go downhill when issues with analog inputs and the display pop up. A teardown reveals a beautifully complex inner assembly of transformers, rectifiers, and circuit boards, giving the DA14 its impressive yet fragile structure. When the critical defective display chip is found, hopes for a full repair dim. His story ends without a revival, but if you want to see a similar attempt that did get resurrected – albeit without those nixie digits – take a look at this LCD transplant we covered previously.

Geochron: Another Time, Another Timeless Tale

October 26, 2024 by Heidi Ulrich 10 Comments

The Geochron World Time Indicator is a clock that doubles as a live map of where the sun is shining on the Earth. Back in its day, it was a cult piece that some have dubbed the “Rolex on the wall.” Wired’s recent coverage of the clock reminded us of just how cool it is on the inside. And to dig in, we like [Attoparsec]’s restoration project on his own mid-1980s Geochron, lovingly fixing up a clock he picked up online.

[Attoparsec]’s recent restoration shares insights into the clock’s fascinating mechanics. Using a synchronous motor, transparent slides, and a lighted platen, the Geochron works like a glorified slide projector, displaying the analemma—a figure-eight pattern that tracks the sun’s position over the year.

But if you’re looking for a digital version, way back in 2011 we showcased [Justin]’s LED hack of FlorinC’s “Wise Clock”, which ingeniously emulated the Geochron’s day-night pattern using RGB LEDs, swapping out the faceplate for a world map printed on vellum. That’s probably a much more reasonable way to go these days. Why haven’t we seen more remakes of these?

Atari’s Pac-Man Flop: How A Classic Went Off-Course

October 25, 2024 by Heidi Ulrich 35 Comments

For fans of retro games, Pac-Man is nothing short of iconic—a game so loved it’s been ported to nearly every console imaginable. But the Atari 2600 version, released in 1982, left players scratching their heads – as laid out in a video by [Almost Something]. Atari had licensed Pac-Man to ride the wave of its arcade success, but the home version, programmed solely by [Todd Fry], missed the mark, turning an arcade icon into a surprising lesson in over-ambitious marketing.

Despite the hype, [Fry] faced an almost impossible task: translating Pac-Man’s detailed graphics and complex gameplay to the Atari’s limited 4 K cartridge with only 128 bytes of RAM. Atari’s strict limitations on black backgrounds and its choice to cut costs by sticking with a 4 K cartridge left the game barely recognizable. The famous pellet-chomping maze became simpler, colors were changed, and the iconic ghosts—reduced to single colors—flickered constantly. And then, Atari went all in, producing twelve million copies, betting on the success of universal appeal. In a twist, Pac-Man did sell in record numbers (over seven million copies) but still fell short of Atari’s expectations, leaving millions of unsold cartridges eventually dumped in a New Mexico landfill.

This debacle even kind of marked Atari’s 1983 decline. Still, Pac-Man survived the hiccup, evolving and outlasting its flawed adaptation on the 2600. If you’re interested in learning more about the ins and outs of game ports, check out the fantastic talk [Bob Hickman] gave during Supercon 2023.

Clockwork Derby: Digital Robo Rally, Steampunk Style

October 16, 2024 by Heidi Ulrich 7 Comments

Inspired by the classic game Robo Rally, [Ytec3D]’s Clockwork Derby takes tabletop gaming to the next level by combining steampunk aesthetics with automation. We recently had the chance to see it live at Hackfest, together with [Ytec3D]’s animatronic tentacle, and we can say that his new take on playful robotics offers a unique experience for game enthusiasts. The 300×420 mm board uses magnets, motors, and card readers to handle up to eight players, creating a smooth, automated version of Robo Rally where players can focus on strategy while the board handles movement.

In Clockwork Derby, game pieces are moved by a magnetic system controlled by the board, which rotates and shifts pieces in real-time. Each player uses a card reader to program moves, with up to five cards per round. The board scans these cards via barcode scanners, so you don’t have to worry about tracking your moves or adjusting game pieces manually. [Ytec3D]’s game rules have been optimized for the automated setup, allowing for smoother gameplay and an emphasis on strategic choices.

The project is a standout for hackers and tinkerers who appreciate blending physical mechanics with digital precision. It’s a great example of how classic games can be modernized with a bit of ingenuity and tech. For those interested in DIY gaming projects or automation, Clockwork Derby is definitely worth exploring. To dive deeper into the build details and see more of the project, visit [Ytec3D]’s project page for an in-person look at this inventive tabletop game!
