When Sony announced they planned to release their own classic/mini/plug-n-play system this year, many fans were filled with excitement at the chance to relive countless classic games from the 90s. However, once the actual list of titles were made public that excitement faded as reality set in. So many favorites like Crash Bandicoot and Spyro the Dragon were left off the final PlayStation Classic list, no doubt due to the complexity of licensing agreements. That will all soon change now that [YifanLu] cracked the PlayStation Classic live on a Twitch stream thus laying the ground work for swapping-in a “more curated” list of classic PlayStation games.
Over the course of three days, [YifanLu] documented the process in real-time of cracking the PlayStation Classic’s security armed with little more than a keyboard. The crux of the hack came from fellow hacker [madmonkey]’s revelation that the firmware update files were signed with a key that had been mistakenly left behind on the device by Sony. Or as [YifanLu] stated, “One key is, ‘Hey am I Sony?’…The other key is saying, ‘Hey I am Sony.’ They distributed the key that identifies [themselves] uniquely and this key doesn’t expire for another 50 years or so.”
Once inside [YifanLu] was able to sideload a prototype image of a Crash Bandicoot over USB. He simply overwrote the first title on the list, Battle Arena Toshinden, and could launch the freshly injected game from the PlayStation Classic menu screen. The video below is from Day 3 of the PlayStation Classic hacking series, so skip to timecode (03:44:45) to see the results in action. For a bit more nuance there are another 15 hours or so of video to catch-up on [YifanLu]’s Twitch page. Here’s to everyone getting their favorite onto the PlayStation Classic in the near future.
It seems crazy having to explain what a piece of technology was like to someone who is barely fifteen years your junior, but yet we have reached that point when it comes to CRTs. There may still be remnants of CRT televisions and monitors left out in the wild, however, the chances that a kid preparing to enter high school has encountered one is slim. While there may be no substitute for the real thing, there is this raw video from [Glenn] who shared his tour of the Sony Trinitron assembly line in the early 2000s.
Sony Electronics’ cathode ray tube manufacturing facility was located alongside headquarters in Rancho Bernado, CA. The facility was shuttered in 2006 when Sony transitioned wholly onto digital displays like the flat-panel LCD line of Bravia televisions. [Glenn]’s video shows that the manufacturing process was almost entirely automated from end to end. A point that was made even more clear with the distinct lack of human beings in the video.
The Trinitron line of televisions first appeared in 1968. At a time where most manufacturer’s were offering black and white picture tubes, Sony’s Trinitron line was in color. That name carried through until the end when it was retired alongside tube televisions themselves. Sony’s focus on technological innovation (and proprietary media formats) made them a giant in the world of consumer electronics for over forty years in the United States, but in the transition to a digital world saw them seeding market share to their competitors.
A quick word of warning as the video below was shot directly on Sony’s factory floor so the machinery is quite loud. Viewers may want to reduce the volume prior to pressing play.
In a complete surprise, Sony has moved to release the latest version of their robotic dog series, Aibo, in North America. The device is already out in Japan, where there are a number of owner’s clubs that would rival any dedicated kennel club. Thanks to the [Robot Start] team, we now have a glimpse of what goes into making the robotic equivalent of man’s best friend in their teardown of an Aibo ERS-1000.
According to Yoshihiro of Robot Start, Aibo looks to be using a proprietary battery reminiscent of the Handycam camcorders. Those three gold contacts are used for charging on the rug shaped power base that Aibo will periodically return to in order to take a”nap”. There are a couple of square OLED screens behind those puppy dog eyes. They are full-color OLEDs somewhere in the one-inch ballpark. Between the screens is a capacitive touch sensor that wraps around to the top of the head that are also pressure sensitive.
Laying out all the major parts out together certainly drives home the complexity of the latest Aibo. It’ll be interesting to see the progression of this device as all of them come equipped with 4G LTE and 802.11 b/g/n WiFi that connect to Sony’s servers for deep learning.
New behaviors are supposed to download automatically as long as the device is under the subscription plan. While Sony has no current plans to integrate with any voice-activated virtual assistant, we can still look forward to the possibility of some expanded functionality from the Hackaday community.
For the rest of the teardown photos make sure to head over to [Yoshihiro]’s write up on Robot Start. Also just in case anybody cared to see what happens when the first generation Aibo ERS-111 from 1999 meets the 2018 Aibo ERS-1000, you’ll find the answer in the video below:
Love it or hate it, you can’t deny that Java has a pretty impressive track record in terms of supported platforms. Available on everything from flip phones to DVD players, not to mention computers, Oracle once famously claimed that Java runs on three billion devices. An estimate that, in truth, is probably on the low side at this point. Especially when [Michael Kohn] keeps figuring out how to run it on increasingly esoteric devices.
[Michael] writes in to tell us that he’s added support for the PlayStation 2 console to Java Grinder, his software for taking Java code and turning it into a native binary for a variety of unexpected platforms. His previous conquests have included the TRS-80 and Atari 2600, so by comparison the PS2 is an almost tame addition to the list.
Let’s be honest, you probably don’t have any desire to run a Java program on Sony’s nearly two decade old game system. But that’s OK. The documentation [Michael] has written up is fascinating anyway, covering specifics of the PS2’s rather unique hardware and quirks he ran into when developing on an emulator and deploying on real hardware. Even if you’ll never put the findings to practical use, it’s absolutely worth a read.
In the video after the break you can see the demo [Michael] came up with booting on a real PS2 to prove the software works. To really put his mark on it, he mentions he wrote and performed the demo’s songs and even drew some of the artwork on paper and scanned it into his computer.
[LittleTern] — annoyed by repetitive advertisements — wanted the ability to mute their Satellite Box for the duration of every commercial break. Attempts to crack their Satellite Box’s IR protocol went nowhere, so they thought — why not simply mute the TV?
Briefly toying with the idea of a separate remote for the function, [LittleTern] discarded that option as quickly as one tends to lose an additional remote. Instead, they’re using the spare RGYB buttons on their Sony Bravia remote — cutting down on total remotes while still controlling the IR muting system. Each of the four coloured buttons normally don’t do much, so they’re set do different mute length timers — customized for the channel or time of day. The system that sends the code to the TV is an Arduino Pro Mini controlling an IR LED and receiver, with a status LED set to glow according to which button was pressed.
If you’re old enough to remember Cathode Ray Tube (CRT) Televisions, you probably remember that Sony sold the top products. Their Trinitron tubes always made the best TVs and Computer Monitors. [Alec Watson] dives into the history of the Sony Trinitron tube.
Sony Color TVs didn’t start with Trinitron — for several years, Sony sold Chromatron tubes. Chromatron tubes used individually charged wires placed just behind the phosphor screen. The tubes worked, but they were expensive and didn’t offer any advantage over common shadow mask tubes. It was clear the company had to innovate, and thanks to some creative engineering, the Trinitron was born.
All color TV’s shoot three electron guns at a phosphor screen. Typical color TVs use a shadow mask — a metal sheet with tiny holes cut out. The holes ensure that the electron guns hit only the red, green and blue dots of phosphor. Trinitrons use vertical bars of single phosphor color and a picket fence like aperture grille. The aperture grill blocks less of the electron beam than a shadow mask, which results in a much brighter image. Trinitrons also use a single electron gun, with three separate cathodes.
[Alec] is doing some amazing work describing early TV systems and retro consumer electronics over on his YouTube channel, Technology Connections. We’ve added him to our Must watch subscription list.
When it comes to microcontroller development boards, we have a plethora of choices at our disposal. Each has its strengths and weaknesses, be they associated with its support and community, its interface capabilities, or its choice of processor family. Most boards you’ll find in our communities come from niche manufacturers, or at least from manufacturers who started as such. Just occasionally though along comes one whose manufacturer you will have heard of, even whose manufacturer the Man in the Street will have heard of.
The board is due to be available sometime early next year, and while it looks as though it will be an interesting device we’d sound a note of caution to Sony. It is not good enough to have an amazing piece of hardware; the software and community support must be more than just make-believe. If they can crack that then they might just have a winner on their hands, if they fail to make any effort then they will inevitably follow Intel into the graveyard of also-ran boards.
Thanks [Chris] for the tip.
