With Sony and Microsoft still a month away from the public release of their next-generation game consoles, you’d expect technical details of their respective systems to still be under a veil of secrecy. But both companies look to be taking things a bit differently this generation, as it becomes increasingly clear that modern consumers are interested in what makes their devices tick. Today, Sony really threw down the gauntlet by beating the tech media to the punch and posting their own in-depth teardown on the new PlayStation 5.
Unsurprisingly, the video after the break is almost entirely in Japanese. But even if you don’t know the language, there’s plenty of interesting details to be had. For one thing, the heatsink and fan that cools the PS5’s AMD CPU and GPU are collectively so massive that they appear to take up most of the console’s internal volume.
In fact, the heatsink itself is so large that the motherboard is actually mounted to it instead of the other way around. So if you want to take out the board, you have to unbolt it from the heatsink and remove it first. In the process you’ll expose the unique liquid metal thermal compound that Sony apparently developed specifically for this application. Good luck to you if any dust gets in that expensive-looking goop.
It’s also interesting to note that, unlike the previous two generations of Sony consoles, the PS5 has no discrete hard drive. Instead, onboard flash with a custom controller is used to provide 825 GB of storage for software. Hopefully Sony has put the requisite amount of R&D into their wear leveling, as a shot flash chip will mean a whole new motherboard. That said, gamers with extensive collections will be happy to see there appears to be an expansion bay where you can install your own M.2 drive.
Sony’s video game division is gearing up for their upcoming PlayStation 5, pushing its predecessor PlayStation 4 off the spotlit pedestal. One effect of this change is Sony ever so slightly relaxing secrecy surrounding the PS4, allowing [Nikkei Asian Review] inside a PlayStation 4 final assembly line.
This article was written to support Sony and PlayStation branding for a general audience, thus technical details are few and far in between. This shouldn’t be a huge surprise given how details of mass production can be a competitive advantage and usually kept as trade secrets by people who knew to keep their mouths shut. Even so, we get a few interesting details accompanied by many quality pictures. Giving us a glimpse into an area that was formerly off-limits to many Sony employees never mind external cameras.
The quoted engineers are proud of their success coaxing robots to assemble soft and flexible objects, and rightly so. Generally speaking robots have a hard time handling non-rigid objects, but this team has found ways to let their robots handle the trickier parts of PS4 assembly. Pick up wiring bundles and flat ribbon cables, then plug them into circuit board connectors with appropriate force. Today’s automated process is the result of a lot of engineers continually evolving and refining the system. The assembly machines are covered with signs of those minds at work. From sharpie markers designating positive and negative travel directions for an axis, to reminders written on Post-It notes, to assembly jig parts showing the distinct layer lines of 3D printing.
We love seeing the result of all that hard work, but lament the many interesting stories still untold. We would have loved a video showing the robots in action. For that, the record holder is still Valve who provided an awesome look at the assembly of the Steam Controller that included a timelapse of the assembly line itself being assembled. If you missed that the first time, around, go watch it right now!
At least we know how to start with the foundations: everything we see on this PS4 assembly line is bolted to an aluminum extrusion big or small. These building blocks are useful whether we are building a personal project or a video console final assembly line, so we’ve looked into how they are made and how to combine them with 3D printing for ultimate versatility.
While there’s still a market for older analog devices such as vinyl records, clocks, and vacuum-tube-powered radio transmitters, a large fraction of these things have become largely digital over the years. There is a certain feel to older devices though which some prefer over their newer, digital counterparts. This is true of the camera world as well, where some still take pictures on film and develop in darkrooms, but if this is too much of a hassle, yet you still appreciate older analog cameras, then this Leica film camera converted to digital might just attract your focus.
This modification comes in two varieties for users with slightly different preferences. One uses a Sony NEX-5 sensor which clips onto the camera and preserves almost all of the inner workings, and the aesthetic, of the original. This sensor isn’t full-frame though, so if that’s a requirement the second option is one with an A7 sensor which requires extensive camera modification (but still preserves the original rangefinder, an almost $700 part even today). Each one has taken care of all of the new digital workings without a screen, with the original film advance, shutters, and other HIDs of their time modified for the new digital world.
The finish of these cameras is exceptional, with every detail considered. The plans aren’t open source, but we have a hard time taking issue with that for the artistry this particular build. This is a modification done to a lot of cameras, but seldom with so much attention paid to the “feel” of the original camera.
Line scan cameras are advanced devices used for process inspection tasks in industrial applications. Used to monitor the quality of silicon wafers and other high-accuracy tasks, they’re often outfitted with top-quality optics that are highly specialised. [Peter] was able to get his hands on a lens for a line-scan camera, and decided to put it to work on some macro photography instead.
Judging by the specs found online, this is a fairly serious piece of kit. It easily competes with top-shelf commercial optics, which is what piqued [Peter]’s interest in the part. Being such a specialised piece of hardware, you can’t just cruise over to eBay for an off-the-shelf adapter. Instead, a long chain of parts were used to affix this lens to a Sony AIII DSLR, converting from threaded fittings to a Nikon mount and then finally to Sony NEX mount.
Further work involved fitting an aperture into the chain to get the lens as close as possible to telecentric. This improves the lens’s performance for certain tasks, and makes focus stacking macro shots more readily achievable – something we’ve seen [Peter] tinker with before.
You never know what you might find when sorting through surplus industrial gear, could could score some high-performance hardware if you know where to look. It’s always great to see a cheap find become a useful instrument in the hacker toolbox!
The quality of a photograph is a subjective measure depending upon a multitude of factors of which the calibre of the camera is only one. Yet a high quality camera remains an object of desire for many photographers as it says something about you and not just about the photos you take. [Neutral Gray] didn’t have a Leica handheld camera, but did have a Sony. What’s a hacker to do, save up to buy the more expensive brand? Instead he chose to remodel the Sony into a very passable imitation.

The Sony A7R is hardly a cheap camera in the first place, well into the four-figure range, so it’s a brave person who embarks on its conversion to match the Leica’s flat-top aesthetic. The Sony was first completely dismantled and it was found that the electronic viewfinder could be removed without compromising the camera. In a bold move, its alloy housing was ground away, and replaced with a polished plate bearing a fake Leica branding.
Extensive remodelling of the hand grip with a custom carbon fibre part followed, with significantly intricate work to achieve an exceptionally high quality result. Careful choice of paint finish results in a camera that a non-expert would have difficulty knowing was anything but a genuine Leica, given that it is fitted with a retro-styled lens system.
We’re not so sure we’d like to brace Leica’s lawyers on this side of the world, but we can’t help admiring this camera. If you’re after a digital Leica though, you can of course have a go at the real thing.
With another summer of heatwaves leaving its mark on our planet, finding a way to stay cool during the day isn’t an easy task. From the morning and afternoon commute in public transport, to busy crowds outside during lunch hour, there are many times when you cannot just find a place inside an airconditioned room to deal with the heat. Exactly for this purpose Sony has successfully completed a kickstarter (in Japanese) on its corporate ‘First Flight’ crowdfunding platform for the Reon Pocket.
Many people probably aren’t aware of Sony’s crowdfunding platform, but it’s a way to gauge the interest from the public for more ‘out there’ products, which do not fit Sony’s usual business model. In this case the Reon Pocket is a Peltier-based device which is placed against the back of one’s neck, from where it can either lower or increase the body’s temperature, reportedly by -13 ℃ and +8.3 ℃ respectively.
Covered in more detail by Engadget and its Japanese sister site, the reported 24 hour battery life refers to the Bluetooth link that connects the device with one’s smartphone, whereas the battery lasts under two hours with the peltier element active. This is probably not too shocking to anyone who knows how a peltier element functions, and how much electricity they consume.
Still, the basic concept seems sound, and there are functioning prototypes. While a 2-hour battery life isn’t amazingly long, it can be just the thing one needs to keep one’s cool during that 15 minute walk to the office in a three-piece suit, without needing a shower afterwards. The device isn’t expensive either, with a projected ¥12,760 (about $117) supplied. Naturally the device will only be on sale in Japan.
Forty years ago this month, a product was launched in Japan that would have such a huge impact on the consumer electronics market that we are still using its descendants today. The story goes that one of the Sony founders would listen to music while traveling for the business, and found the company’s existing products cumbersome and awkward so asked his engineers to design something more convenient.
The resulting prototype became the Sony MDL-3L2, a set of miniaturised hi-fi headphones with distinctive foam earpads and a sliding metal headband that in total weighed an astoundingly svelte 45 g. It was paired with a cassette player called a “Walkman” derived from the company’s existing recorder that had been intended for journalists, and went on to sell in the millions. The market for headphones would never be the same again, and if you have a set of lightweight cans in your possession then this was their revolutionary progenitor.
But Hang On, What’s So Special About Headphones?
You probably won’t have heard the Walkman’s 40th anniversary described in those terms in the various reports covering the event, because of course the social impact of the portable music player rather than its headphones is what people remember. The joy of making a mix tape, of listening to The Human League on the bus, and of the adult disapproval of anything involving Kids Having Fun. Previously, music had been a static affair involving bulky record players, but now it could be taken anywhere. The other youth audio icon of that era, the boombox, simply couldn’t match the Walkman, and everybody wanted one. Continue reading “Forget The Walkman: It’s The Headphones”→
