Official Teardown Gives Unexpected Look Into PS5

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.

Between this and the recent PS4 assembly line tour, it’s refreshing to see a company like Sony be a bit more transparent. After years of adversarial treatment from the tech giants, we’d almost forgotten that the customer is supposed to be king. Continue reading “Official Teardown Gives Unexpected Look Into PS5”

Hacking A Netgear Router

Have you ever wanted to watch someone reverse engineer a piece of hardware and pick up some tips? You can’t be there while [Jeremy] tears open a Netgear N300 router, but you can see his process step by step in some presentation charts, and you’ll get a few ideas for the next time you want to do something like this.

The first part of the presentation might be a little basic for most Hackaday readers, but presumably, the intended audience might not know much about soldering or multimeters. But we enjoyed the methodology used to work out the UART pins on the board. We would have read the baud rate with the scope, which [Jeremy] does, but he also mentions a script to work it out and create a minicom profile that looked interesting.

Teardown: BlackBerry Smart Card Reader

Years before Steve Jobs showed off the first iPhone, the BlackBerry was already the must-have accessory for mobile professionals. Back then, nobody was worried about watching movies or playing the latest games on their mobile devices, they just wanted a secure and fast way to send and receive email on the go. For that, the BlackBerry was king.

Fast forward to today, and the company is just a shell of what it once was. They don’t even bother making their own hardware anymore. Over the last several years they’ve opted to partner with a series of increasingly obscure manufacturers to produce a handful of lackluster Android phones so they still have something to sell to their dwindling userbase. Anyone excited about the new 5G BlackBerry being built by Texas start-up OnwardMobility? Did you even know it was in the works before now?

A DoD Common Access Card

But this article isn’t about BlackBerry phones. It’s about something that’s evenĀ more irrelevant to consumers: the BlackBerry Smart Card Reader. Technically, this little device isn’t dependent on the phones of the same name, but it makes sense that Research In Motion (which eventually just renamed itself to BlackBerry Limited) would market the gadget under the brand of their most popular product. Though as you might expect, software was available to allow it to work with the BlackBerry phone that you almost certainly owned if you needed a dedicated smart card reader.

For those who might not be aware, a smart card in this context is a two-factor authentication token contained in an ID card. These are used extensively by organizations such as the Department of Defense, where they’re known as Common Access Cards, that require you to insert your ID card into a reader before you can log into a secure computer system. This sleek device was marketed as a portable reader that could connect to computers over USB or Bluetooth. Worn around your neck with the included lanyard, the battery-powered reader allowed the card itself to remain on the user’s body while still being readable by nearby devices.

Civilians will recognize the basic technology from modern “Chip and PIN” debit and credit cards, but we’ve never had to stick one of those into our laptop just to log in. To be sure, the BlackBerry Smart Card Reader was never intended for the average home computer user, it was sold to companies and organizations that had tight security requirements; which just so happened to be the same places that would likely already be using BlackBerry mobile devices.

Of course, times and technology change. These devices once cost $200 apiece and were purchased in vast quantities for distribution to trusted personnel, but are now all but worthless. Even in new and unopened condition, they can be had for as little as $10 USD on eBay. For that price, it’s certainly worth taking a peek inside. Perhaps the hacker community can even find new applications for these once cutting-edge devices.

Cheap Current Probe Gets Good Review

A current probe isn’t a very common fixture on most workbenches because they are pretty expensive. [VoltLog] looks at a fairly inexpensive current probe from Micsig. He seemed impressed with the workmanship and it looks similar to more expensive offerings. There are two models with different bandwidth numbers (800 kHz and 2 MHz). It can measure current on a 10A and 100A scale.

According to [VoltLog] comparable probes from other vendors are more expensive and have lower bandwidth. He also liked that the device powers from USB since most newer scopes will have a USB port available.

Teardown: Mini GPS Jammer

If you spend enough time trolling eBay for interesting electronic devices to take apart, you’re bound to start seeing suggestions for some questionable gadgets. Which is how I recently became aware of these tiny GPS jammers that plug directly into an automotive 12 V outlet. Shipped to your door for under $10 USD, it seemed like a perfect device to rip open in the name of science.

Now, you might be wondering what legitimate uses such a device might have. Well, as far as I’m aware, there aren’t any. The only reason you’d want to jam GPS signals in and around a vehicle is if you’re trying to get away with something you shouldn’t be doing. Maybe you’re out driving a tracked company car and want to enjoy a quick two hour nap in a parking lot, or perhaps you’re looking to disable the integrated GPS on the car you just stole long enough for you to take it to the chop shop. You know, as one does.

But we won’t dwell on the potentially nefarious reasons that this device exists. Hackers have never been too choosy about the devices they investigate and experiment with, and there’s no reason we should start now. Instead, let’s take this piece of gray-area hardware for a test drive and see what makes it tick.

An Old Calculator Lives Again

There was a time when any electronics student would have a slide rule hanging off their belt. By the 1970s, the slide rule changed over to an electronic calculator which was a pricy item. Today you can buy calculators at the dollar store. [JohnAudioTech] pulled out an old Radio Shack vacuum fluorescent display (VFD) calculator and found it didn’t work. Obviously, that means it is time to open it up.

It is fun to see one of these old devices opened up again. Consumer electronics with big through-hole ICs! Troubleshooting the device wound up being anti-climatic, as a broken wire to the battery compartment explained the whole thing.

As a teardown, though, this is a fun video. Not only are all the parts through-hole, but the PCB is clearly a manual layout with serpentine traces flowing across the board like some sort of art piece. Continue reading “An Old Calculator Lives Again”

Gaze Inside The Valve Index VR Headset In Detailed Teardown

Valve’s unique multilayer lenses are far thinner than one might expect.

Want to see what exactly is inside the $500 (headset only price) Valve Index VR headset that was released last summer? Take a look at this teardown by [Ilja Zegars]. Not only does [Ilja] pull the device apart, but he identifies each IC and takes care to point out some of the more unique hardware aspects like the fancy diffuser on the displays, and the unique multilayered lenses (which are much thinner than one might expect.)

[Ilja] is no stranger to headset hardware design, and in addition to all the eye candy of high-res photographs, provides some insightful commentary to help make sense of them. The “tracking webs” pulled from the headset are an interesting bit, each is a long run of flexible PCB that connects four tracking sensors for each side of the head-mounted display back to the main PCB. These sensors are basically IR photodiodes, and detect the regular laser sweeps emitted by the base stations of Valve’s lighthouse tracking technology. [Ilja] also gives us a good look at the rod and spring mechanisms seen above that adjust distance between the two screens.

Want more? [Ilja] also has a gallery of high-resolution images available for those you who fancy a closer look. Also, if you missed it, we covered an examination of the Index’s optical design as part of everything you probably didn’t know about field of view in head-mounted displays.
