Make Your Own Play Station (The Space Is Important)

The early history of the Sony Playstation lies in a stillborn collaboration between Nintendo and Sony to produce an SNES with a CD-ROM drive. So the story goes, Nintendo’s Philips deal angered Sony, who decided to make their own console line, and the rest is history. A very small number of prototypes were made, badged as “Play Station,” and should you find one that escaped today, you’re sitting on a fortune. [James] doesn’t have one, but he did have half a Playstation and an SNES shell, so he could make an ungodly child of the two consoles that you can see in the video below the break.

Those Playstation CD-ROM drives were notorious for melting back in the day, so it’s no surprise they’re still for sale today. Thus, he was able to bring the Sony back to life. What follows is an episode of console cutting worthy of a slasher horror movie, as instead of a bit of fine Dremmeling, he brings out an angle grinder and slices away with abandon. We don’t like the Nintendo switch carrying mains voltage, but we’re fine with the PlayStation expansion connector going away. The Nintendo eject button needs a hack to operate the Playstation door open button when pressed. It’s cool to see the board has a mod chip. We used to fit those as a sideline in a previous life.

A Classic Shortwave Radio Restored

Before the Internet, if you wanted to hear news from around the world, you probably bought a shortwave receiver. In the golden age of world band radio, there was a great deal of high-quality programming on the shortwave bands and a large variety of consumer radios with shortwave bands. For example, the Sony CRF-160 that [M Caldeira] is restoring dates from the late 1960s or early 1970s and would have been a cool radio in its day. It retailed for about $250 in 1972, which sounds reasonable, but — don’t forget — in 1972 that would have been a 10% downpayment on a new car or enough to buy a Big Mac every day for a year with change left over.

As you can see in the video below, the radio seemed to work well right out of the gate, but the radio needed some rust removal and other sprucing up. However, it is an excellent teardown, with some tips about general restoration.

A Wigglegram Lens With Variable Aperture

Wigglegrams are those weird animated pictures you’ve seen that seem to generate a 3D-like effect. [scealux] had built lenses to take such pictures before, but wanted to take things to the next level. Enter the Wigglegram Lens, version 2.

In building a new lens for the Open Sauce ’23 event, [scealux] wanted to get variable aperture working, while also improving focus speed. The lens was also intended for use with a Sony A7R3. Unlike his previous effort, this lens would only work on the full-frame Sony FE mount cameras.

The lens uses a bevy of 3D printed parts, along with plastic lenses salvaged from old disposable cameras. When assembled, it takes three photos simultaneously on one single frame. They can then be reassembled into a Wigglegram by post-processing on a computer. The results are grainy and rough, but yet somehow compelling.

If you want to see [scealux]’s original build for Sony E-mount cameras, we covered it here. Video after the break.

Closing In On A PC Enabled PSVR2

When the PlayStation VR2 headset was released, people wondered whether it would be possible to get the headset to work as a PC VR headset. That would mean being able to plug it into a PC and have it work as a VR headset, instead of it only working on a PS5 as Sony intended.

Enthusiasts were initially skeptical and at times despondent about the prospects, but developer [iVRy]’s efforts recently had a breakthrough. A PC-compatible VR2 is looking more likely to happen.

So far [iVRy] is claiming they have 6 DOF SLAM (Simultaneous Localisation and Mapping), Prox sensor, and stereo camera data.

Most of the juicy bits are paywalled behind [iVRy]’s Patreon.  We’re hoping the jailbreak process will eventually be open-sourced.

The PS VR2 headset is quite unlike a PC VR headset in a number of ways, and it has not been historically easy to work with Sony’s products from a reverse-engineering perspective, whether it’s an attempt to improve the user experience of an annoying headset, or an attempt to understand the not-even-remotely-sanely-designed protocols behind the Sony Memory Stick. Getting the PS VR2 headset to work in a way it wasn’t intended was expected to be an uphill battle.

It’s not a finished job, but judging by the progress regularly shared on [iVRy]’s Twitter account, it might only be a matter of time.

Hackaday Links: June 11, 2023

As Tom Nardi mentioned in this week’s podcast, the Northeast US is pretty apocalyptically socked in with smoke from wildfires in Canada. It’s what we here in Idaho call “August,” so we have plenty of sympathy for what they’re going through out there. People are turning to technology to ease their breathing burden, with reports that Tesla drivers are activating the “Bioweapon Defense Mode” of their car’s HVAC system. We had no idea this mode existed, honestly, and it sounds pretty cool — the cabin air system apparently shuts off outside air intake and runs the fan at full speed to keep the cabin under positive pressure, forcing particulates — or, you know, anthrax — to stay outside. We understand there’s a HEPA filter in the mix too, which probably does a nice job of cleaning up the air in the cabin. It’s a clever idea, and hats off to Tesla for including this mode, although perhaps the name is a little silly. Here’s hoping it’s not one of those subscription services that can get turned off at a moment’s notice, though.

Watch Sony Engineers Tear Down Sony’s VR Hardware

Teardowns are great because they let us peek not only at a product’s components, but also gain insight into the design decisions and implementations of hardware. For teardowns, we’re used to waiting until enthusiasts and enterprising hackers create them, so it came as a bit of a surprise to see Sony themselves share detailed teardowns of the new PlayStation VR2 hardware. (If you prefer the direct video links, Engineer [Takamasa Araki] shows off the headset, and [Takeshi Igarashi] does the same for the controllers.)

The “adaptive trigger” module responsible for the unique feedback.

One particularly intriguing detail is the custom tool [Araki] uses to hold the headset at various stages of the disassembly, which is visible in the picture above. It looks 3D-printed and carefully designed, and while we’re not sure what it’s made from, it does have a strong resemblance to certain high-temperature SLA resins. Those cure into hard, glassy, off-yellow translucent prints like what we see here.

As for the controller, we get a good look at a deeply interesting assembly Sony calls their “adaptive trigger”. What’s so clever about it? Not only can it cause the user to feel a variable amount of resistance when pulling the trigger, it can even actively push back against one’s finger, and the way it works is simple and effective. It is pretty much the same as what is in the PS5 controller, so to find out all about how it works, check out our PS5 controller teardown coverage.

The headset and controller teardown videos are embedded just below. Did anything in them catch your interest? Know of any other companies doing their own teardowns? Let us know in the comments!

Hackaday Links: January 8, 2023

Something odd is afoot in the mountains around Salt Lake City, Utah, at least according to local media reports of remote radio installations that have been popping up for at least the past year. The installations consist of a large-ish solar panel, a weatherproof box full of batteries — and presumably other electronics, including radios — and a mast bearing at least one antenna. Local officials aren’t quite sure who these remote setups belong to or what they’re intended to do, but the installations obviously represent a huge investment in resources.

The one featured in the story was located near the summit of Twin Peaks, which is about 11,000 feet (3,300 meters) in elevation, which with that much gear was probably a hell of a hike. Plus, the owner took great pains to make sure the site would withstand the weather, with antenna mast guy wires that must have required lugging a pretty big drill up with them. There aren’t any photos of the radios in the enclosure, but one photo shows a 900-MHz LORA antenna, while another shows what appears to be a panel antenna, perhaps pointing toward another site. So maybe a LORA mesh network? Some comments in the Twitter thread show most people are convinced this is a Helium crypto mining rig, but the Helium Explorer doesn’t show any hotspots listed in that area. Either way, the owners are out of luck, since their gear is being removed if it’s on public land.
